In the electronic apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the electronic device of the present invention may be disposed in a detection device of the newly added service host, and the electronic device calls a detection program of the newly added service host stored in the memory 1005 through the processor 1001 and executes the detection method of the newly added service host provided in the embodiment of the present invention.
An embodiment of the present invention provides a method for detecting a newly added service host, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of a method for detecting a newly added service host according to the present invention.
In this embodiment, the method for detecting the newly added service host includes the following steps:
step S10: when a host detection instruction is received, a target service system is determined according to the host detection instruction, and a target service host is selected from the target service system.
It should be noted that, the execution main body in this embodiment may be the detection device of the newly added service host, and the detection device of the newly added service host may be an electronic device such as a personal computer, a server, and the like, or may also be other devices that can achieve the same or similar functions.
It should be noted that the newly added service host detection device may be a disaster recovery backup server, or may be an independent server that is connected to the disaster recovery backup server and the target service system through a network. The host detection instruction may be an instruction sent by the other device to the host detection device of the newly added service. The host detection instruction may include a service system identifier, and determining the target system according to the host detection instruction may be to search corresponding service system information in a system information table according to the service system identifier included in the host detection instruction to determine the target service system. The service system information may include information including the number of service host clusters, the number of service hosts in each cluster, network segments used by each service host cluster, and the like in the service system.
In actual use, the selecting of the target service host in the target service system may be to search backup host information of each service host of the target service system according to the service system information, determine a network Identifier (ID) corresponding to each service host in the target service system according to the backup host information, determine all used network segments of the target service system according to the network ID, and then randomly select one service host in each network segment as the target service host. The network ID is used to indicate which network the service host belongs to, and computers with the same network ID can directly perform two-layer network communication without being connected through a router, that is, data link layers in an Open System Interconnection Reference Model (OSI) seven-layer network protocol stack, and the computers with different network IDs must be connected through a router; computers with the same network ID form a network called a local network (network segment).
As shown in fig. 3, fig. 3 is a schematic diagram of service host distribution of a target service system, where the target service system includes 5 reported service hosts, such as A, B, C, D, E, etc., the IP addresses used by the reported service hosts are 172.16.2.4, 172.16.2.5, 192.168.4.5, 192.168.4.6, 222.166.7.9, the target service system includes three sub-routers, the IP addresses are 172.16.2.1, 192.168.4.1, 222.166.7.1, the three sub-routers are connected to a main router, the target service system has an unpredicted new server, i.e., a new service host, and the IP address of the new service host is 192.168.4.9, and then the network ID of each reported service host can be obtained, and then the obtained network ID is deduplicated to determine that there are three network segments 172.16.2.0/24, 192.168.4.0/24, and 222.166.7.0/24 used in the target service system, at this time, one service host can be randomly extracted in each network segment as the target service host, for example: target service hosts are 3 service hosts such as A, C, E.
Step S20: and sending a host scanning instruction to the target service host to enable the target service host to perform host scanning according to the host scanning instruction and feed back network segment host information when the host scanning is finished.
It should be noted that the network segment host information may include an IP address and a service host identifier corresponding to the IP address. The target service host can obtain the network segment where the target service host locates when receiving the host scanning instruction, obtain all the IP addresses (Internet Protocol addresses) in the network segment where the target service host locates, determine whether each IP Address has a corresponding network segment host identity, and finally generate and feed back network segment host information according to the IP addresses of all the inquired network segment host identities and the corresponding network segment host identities. The network segment host identifier may be a mac Address (Media Access Control Address) of the service host, and determining whether each IP Address has a corresponding network segment host identifier may be scanning through an arp (Address Resolution protocol) protocol to determine whether each IP Address has a corresponding mac Address.
It can be understood that, in the use process of each network segment, some special IP addresses in the network segment are not set with service hosts, and such special IP addresses can be filtered out without host scanning, for example: for segment 192.168.4.0/24, the range of IP addresses is typically 192.168.4.0-192.168.4.255, wherein 192.168.4.0 is typically unused IP and can be filtered, 192.168.4.255 typically broadcasts the used IP address and typically does not set a service host, and therefore, can also be filtered.
In practical use, the newly added service host detection device may periodically send a host scanning instruction to the target service host at a preset time interval, where the preset time interval may be preset by a user, for example: and setting the preset time interval to be 5 minutes, and sending a host scanning instruction to the target service host every 5 minutes by the newly added service host detection equipment.
In practical use, the scanning of one IP address may be used as a complete host scanning process, network segment host information is generated and fed back after a single IP address is scanned, or the scanning of all IP addresses may be used as a complete host scanning process, and network segment host information is generated and fed back uniformly after the scanning is finished, which is not limited in this embodiment.
Further, if the target service host needs to acquire its own network segment when receiving the host scanning instruction, which may slow down the host scanning process, in order to overcome the above-mentioned defect and increase the host scanning speed, step S20 in this embodiment may include:
acquiring a service network segment corresponding to the target service host; generating a host scanning instruction according to the service network segment; and sending the host scanning instruction to the target service host to enable the target service host to perform host scanning according to the host scanning instruction, acquiring network segment host identifiers corresponding to all network segment IP addresses in the service network segment, and generating network segment host information and feeding back the network segment host information according to the network segment host identifiers and the service network segment when the host scanning is finished.
It should be noted that the service network segment may be a network segment where a service host is located. The newly added service host detects that information such as IP addresses of all the service hosts are obtained when the target service host is selected, and counts network IDs of all the service hosts, so that the service network segment of each target service host can be directly determined.
Further, since the target service host may have a provisioned host in the same network segment when performing host scanning, the generated network segment host information also includes information such as an IP address and a mac address of the provisioned service host, so that the provisioned host information of the provisioned service host can be found when searching for the corresponding provisioned host information in the provisioned host information table according to the network segment host information, which wastes computing resources, and in order to overcome the above-mentioned defects, the step of generating a host scanning instruction according to the service network segment may include:
acquiring information of a backup host corresponding to the service network segment; and generating a host scanning instruction according to the service network segment and the information of the backup host.
Correspondingly, the step of sending the host scanning instruction to the target service host to enable the target service host to perform host scanning according to the host scanning instruction, obtain segment host identifiers corresponding to each segment IP address in the service segment, and generate segment host information and feed back the segment host information according to the segment host identifiers and the service segment when the host scanning is completed may include:
sending the host scanning instruction to the target service host to enable the target service host to perform host scanning according to the host scanning instruction, acquiring network segment host identifiers corresponding to all network segment IP addresses in the service network segment, generating network segment host information according to the network segment host identifiers and the service network segment when the host scanning is completed, performing data filtering on the network segment host information according to the backup host information, and feeding back the network segment host information when the data filtering is completed.
It should be noted that the information of the provisioning host may include information such as a name of the service host, an IP address of the service host, and a network segment host identifier of the service host.
It can be understood that all the preparation host information in the service network segment corresponding to the target service host is added to the host scanning instruction, and then the target service host can analyze the host scanning instruction when receiving the host scanning instruction, so as to obtain the service network segment and the preparation host information corresponding to the service network segment, and when the host scanning is completed, the generated network segment host information can be subjected to data filtering according to the preparation host information corresponding to the service network segment, and the information corresponding to all the prepared service hosts included in the network segment host information is removed, so that the network segment host information does not include the information of the prepared service hosts, thereby saving computing resources.
Step S30: and searching corresponding backup host information in the backup host information table according to the received network segment host information.
It should be noted that the segment host information may simultaneously include a plurality of IP addresses and service host identifiers corresponding to the IP addresses, and at this time, the received segment host information may be split into a plurality of segment host information, so that each segment host information only includes one IP address and a service host identifier corresponding to the IP address. And then, respectively searching corresponding backup host information in a backup host information table according to the split multiple network segment host information.
It should be noted that, when the segment host information is received, it may be determined whether the segment host information includes information such as an IP address and a corresponding mac address, and step S30 is executed only when the segment host information includes the information, so that it may be avoided that a null value is used for searching, and a situation that a query error is reported or a large amount of data is queried occurs.
Further, since the service hosts may be down in practical use, the service hosts of the same IP address may be the service hosts to be replaced after the previous service host is down, the service host identity of the service host is different from the previous service host, but the IP address is the same, but the service host is not reported, or due to the service regulation, the service host stealing occurs, for example, the service host originally used in the A service host cluster is stolen for use in the B service host cluster, the service host IP address changes, but the service host identity does not change, the service host should be provisioned again, therefore, in order to overcome the above-mentioned defect, step S30 in this embodiment may include:
determining a network segment IP address and a network segment host identity corresponding to the network segment IP address according to the network segment host information; and searching backup host information corresponding to the network segment host information in a backup host information table according to the network segment IP address and the network segment host identifier.
It should be noted that the network segment IP address may be an IP address corresponding to a service host corresponding to the network segment host information in the service network segment.
It can be understood that the backup host information corresponding to the segment host information is searched in the backup host information table by simultaneously using the segment IP address and the segment host identifier, so that the missing detection phenomenon caused by the conditions of different segment host identifiers with the same IP address or different IP addresses and segment host identifiers and the like can be avoided.
Step S40: and when the backup host information corresponding to the network segment host information is not found, judging that the service host corresponding to the network segment host information is a newly added service host.
It can be understood that, if the backup host information corresponding to the segment host information is not found, it is stated that the service host corresponding to the segment host information is not backed up, and therefore, it can be determined that the service host corresponding to the segment host information is the new service host, that is, the new service host exists in the target service system.
Further, in order to facilitate the user to determine which service host is the new service host, after step S40, the method may further include:
generating a new host report according to the network segment host information; and storing the new host report to a preset storage space, and displaying the new host report to a user.
It can be understood that the network segment host information may include information such as the network segment IP address and the network segment host identifier of the service host, and a new host report is generated according to the network segment host information and displayed to the user, so that the user can quickly specify the network segment IP address and the network segment host identifier of the newly added service host, and the user can quickly locate the newly added service host, so as to perform data disaster recovery backup on the newly added service host. The new host report is stored in the preset storage space, so that the user can conveniently remind or search by himself when the user timely knows the new host report.
In the embodiment, when a host detection instruction is received, a target service system is determined according to the host detection instruction, and a target service host is selected from the target service system; sending a host scanning instruction to a target service host to enable the target service host to perform host scanning according to the host scanning instruction and feeding back network segment host information when the host scanning is finished; searching corresponding backup host information in a backup host information table according to the received network segment host information; and when the backup host information corresponding to the network segment host information is not found, judging the service host corresponding to the network segment host information as a newly added service host. Because the service hosts in the same network segment can directly carry out two-layer network communication, host scanning is carried out through the target service host, and whether a new service host exists in the network segment where the target service host is located can be quickly determined according to the host scanning result.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for detecting a newly added service host according to a second embodiment of the present invention.
Based on the first embodiment, after step S10, the method for detecting a new service host in this embodiment further includes:
step S20': and sending a network detection instruction to the target service host to enable the target service host to carry out network connection detection according to the network detection instruction, and feeding back information of the connection host when the network detection is finished.
It should be noted that, since the service hosts with different network IDs cannot directly perform two-layer network communication, scanning by the arp protocol is also impossible. If a new service host is added in a newly used network segment, namely, the new service host is added in the case of an independent network, the arp protocol cannot be used for scanning to determine whether a new service host exists. The newly added service hosts generally have more or less contact with the existing servers, and do not exist in isolation, so that the newly added server can be found by scanning network connection, and at this time, the selection of the target service host in the target service system in step S10 may be to use each already reported service host in the target service system as the target service host.
For example: as shown in fig. 5, fig. 5 is a service host distribution diagram of a target service system when a new service host is added to an independent network, where A, B, C, D four reported hosts exist in the target service system, IP addresses are 172.16.2.4, 172.16.2.5, 192.168.4.5, and 192.168.4.6, the target service system includes three sub-routers, the IP addresses are 172.16.2.1, 192.168.4.1, and 222.166.7.1, the three sub-routers are connected to a main router, and an IP address of a newly added service host is 222.166.7.9, where the newly added service host is added to a network segment 222.166.7.0/24 that is newly put into use, and no service host that has been reported exists in the network segment.
It should be noted that, when receiving the network detection instruction, the target service host queries the service host that has undergone network connection with the target service host, extracts the IP address of the service host to generate connection host information, and feeds the connection host information back to the newly added service host detection device. The target service host checks whether the service host connected to the target service host via the network is queried through a command such as netstat, or through a record called by a system function, which is not limited in this embodiment.
In actual use, the newly added service host detection device may periodically send a network detection instruction to each target service host at a preset time interval, where the preset time interval may be preset by a user, for example: and setting the preset time interval to be 5 minutes, and sending a network detection instruction to each target service host every 5 minutes by the newly added service host detection equipment.
Step S30': and searching corresponding information of the preparation host in the information table of the preparation host according to the received information of the connection host.
It should be noted that, the searching for the corresponding provisioning host information in the provisioning host information table according to the received connection host information may be that, when the received connection host information is received, the IP address of the service host performing network connection with the target service host is determined according to the connection host information, and then the corresponding provisioning host information is searched in the provisioning host information table according to the IP address.
Step S40': and when the backup host information corresponding to the connection host information is not found, judging that the service host corresponding to the connection host information is a newly added service host.
It should be noted that, if the provisioning host information corresponding to the connection host information is not found, it is determined that the service host corresponding to the connection host information is not provisioned, and therefore, it can be determined that the service host corresponding to the connection host information is the new service host.
It is to be understood that, in order to facilitate the user to determine which service host is the new service host, the new host report may also be generated according to the information of the connected hosts after step S40', and the new host report may be stored and presented to the user.
Further, since part of the service system is used externally, not only internally, and therefore, the user host may be an external user host rather than a system host, where the user host is connected to the target service host through a network, and at this time, if it is determined whether the service host corresponding to the connection host information is a new service host only according to whether the provisioning host information corresponding to the connection host information can be found, a large number of false alarms may exist, and in order to overcome the above defect, before step S40 of this embodiment, the method may further include:
and acquiring a preset service system network segment corresponding to the target service system.
Accordingly, step S40 of this embodiment may include:
when the backup host information corresponding to the connection host information is not found, determining the IP address of the connection host according to the connection host information; and when the IP address of the connecting host belongs to the preset service system network segment, judging that the service host corresponding to the connecting host information is a new service host.
It should be noted that the IP address of the connection host may be an IP address of a host that is network-connected to the target service host and corresponds to the connection host information. The preset service system network segment can be preset by a user, the preset service system network segment can be a plurality of network segments used by the service system, if the IP address of a certain host belongs to any one of the preset service system network segments, the IP address can be judged to belong to the preset service system network segment, that is, the host is the service host in the service system.
It can be understood that if the provisioning host information corresponding to the connection host information is not found, it may be said that the host has not been provisioned, if the connection host IP address belongs to the preset service system network segment, it may be said that the host corresponding to the connection host information is a service host, if one host has not been provisioned and it may be determined that the host is a service host, it may be determined that the host is a new service host, and therefore, it may be determined that the service host corresponding to the connection host information is a new service host.
In this embodiment, a network detection instruction is sent to the target service host, so that the target service host performs network connection detection according to the network detection instruction, and feeds back connection host information when network detection is completed; searching corresponding information of the preparation host in the information table of the preparation host according to the received information of the connection host; and when the backup host information corresponding to the connection host information is not found, judging that the service host corresponding to the connection host information is a newly added service host. Because the newly added service host in the independent network generally has more or less contact with the existing service host and does not exist in isolation, the network connection detection is carried out through the target service host, and the newly added service host in the independent network can be quickly found according to the network connection detection result.
In addition, an embodiment of the present invention further provides a storage medium, where the storage medium stores a new service host detection program, and the new service host detection program, when executed by a processor, implements the steps of the new service host detection method described above.
