All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
At present, management of a large number of hosts is generally realized at a management end through a broadcasting mode of the management end and the host end or a means of manually adding host information by technicians, but the efficiency of adding the host information is lower. Based on the above technical problems, the present embodiment provides a method for adding host information, which can improve efficiency of adding a host, and referring to fig. 1, fig. 1 is a flow chart of the method for adding host information, which is provided in the embodiment of the present application, and is applied to a host management end, and specifically includes:
s101, sending a collection message to all hosts through a multicast tunnel;
the multicast tunnel is in the form of an IP-based multicast transmission mode, and IP-based multicast refers to that an IP message is forwarded to a specific group of receivers after being sent from a data source. Compared with the traditional unicast technology, the method can effectively save network bandwidth and reduce network load, and is often used in network services such as online live broadcast, network television, real-time data transmission, multimedia conference and the like.
In this embodiment, a multicast group is created, where the multicast group includes a host management end and all hosts, where the host management end is used as a sender of data and sends the data to a specific group of receivers, i.e. all hosts, where the receivers share an IP address (a class D address specific to the multicast group).
Of course, in this embodiment, sending the collection message to all hosts through the multicast tunnel may specifically include: and sending the collected message to the switch through the multicast tunnel, and then sending the collected message to all hosts by the switch. In the Incloude Sphere and Incloud oil product series, the networking form of the servers is shown in fig. 2, and fig. 2 is a schematic diagram of message transmission provided in the embodiment of the present application, and a group of servers and a management server are connected through a switch.
The embodiment does not limit the collected message, and the user can set the collected message in a user-defined manner, so long as the purpose of the embodiment can be achieved. The collecting the message may include: the second operation code, the management end configuration information, the host management end name, the management ssh key and the management end check value. Wherein, the second operation code may be 0x0001, defined as the management end collecting server host information; management end configuration information including IP of management end, software configuration information, etc.; the host management end name and the management ssh key are convenient for the management end and the server host end to avoid secret access; and the check value adopts the crc check to the transmission content (operation code, configuration information, host name and the like) so as to check whether the transmission content is correct or not at the host end.
S102, obtaining a response message which corresponds to the collection message and is fed back by the host;
after receiving the collection message, the host generates a corresponding response message, and then sends the response message to the host management end. The response message includes the host information, and of course, may also include other information, which may be set by the user in a user-defined manner, so long as the purpose of the embodiment can be achieved.
S103, obtaining host information according to the response message, and adding the host information into the cluster information.
And obtaining host information according to the response message, and then adding the host information into the cluster information, thereby completing the addition of the host into the production environment. The method and the system realize quick addition of each installed host to the production environment in the large-scale deployed environment. The cluster information comprises host information corresponding to a plurality of hosts. The host information comprises a MAC address, a host name, a host ssh key, a host model, a RAID card model, a firmware version, a PCI address, a network card model and state, a CPU model and a memory.
Further, when the response message includes the host information and the first operation code, in order to improve efficiency, obtaining the host information according to the response message includes: reading a first operation code from the response message, and judging whether the first operation code is a first preset operation code or not; if the first operation code is a first preset operation code, the host information is read from the response message.
In this embodiment, the first preset operation code may be 0x0002, specifically, the host returns the current host information to the host management end. Only when the first operation code is a first preset operation code, reading host information from the response message; if the first operation code is not the first preset operation code, there may be a loss of the response message or a modification of the response message, and the operation is ended or an alarm response is sent. Therefore, the first operation code is set in the response message, so that the host management end can obtain the host information more efficiently and safely.
Further, when the response message further includes a check value, in order to ensure that the data is not modified, if the first operation code is a first preset operation code, reading the host information includes: if the first operation code is a first preset operation code, reading other information except the first operation code from the response message; the other information comprises a check value and current host information, a target check value is obtained according to the current host information, and whether the check value is consistent with the target check value or not is judged; and if the check value is consistent with the target check value, determining the current host information as the host information.
If the first operation code is a first preset operation code, reading a check value and current host information; and performing crc calculation according to the current host information to obtain a target check value, comparing the target check value with the check value, if the two are consistent, determining that the current host information is not modified, if the two are inconsistent, determining that the current host information is modified, stopping any operation at the moment, or sending out alarm information. Therefore, the embodiment ensures the safety of the data by checking.
Further, the method further comprises the following steps: and reading the host ssh key from the response message, and storing the host ssh key. The host ssh key is a secret key which is accessed by the host management end and the host in a secret-free mode. And ensuring the secret-free access between the host and the host management terminal.
Based on the above technical solution, the embodiment adopts the multicast tunnel mode to send the collecting message to all the hosts, and adds the host information corresponding to the host to the cluster information after receiving the response message fed back by the host, thereby realizing the automatic discovery of the host and improving the efficiency of the host discovery.
Referring to fig. 3, fig. 3 is a flowchart of another method for adding host information, applied to a host, according to an embodiment of the present application, including:
s201, acquiring a collection message sent by a host management end through a multicast tunnel;
further, the method further comprises the following steps:
and reading the management ssh key from the collection message, and storing the management ssh key.
And the ssh key is managed, so that the management end and the server host end are convenient to access without secret. The management ssh key is a secret key which is accessed by a host management end and a host in a secret-free manner. And ensuring the secret-free access between the host and the host management terminal.
Further, in order to ensure the safety of the information and improve the efficiency, generating a response message according to the collected message by using the host information includes: reading a second operation code in the collected message, and judging whether the second operation code is a second preset operation code or not; if the second operation code is a second preset operation code, reading other management information except the second operation code from the collection message; other management information comprises a management end check value and current management information; acquiring a current management end check value according to the current management information, and judging whether the management end check value is consistent with the current management end check value or not; if the check value of the management end is consistent with the check value of the current management end, acquiring host information; and generating a response message according to the host information.
Wherein, the collecting message includes, but is not limited to: the second operation code, management end configuration information (current management information), host management end name and management ssh key, and management end check value. Whether the second operation code is consistent with the second preset operation code or not is judged to determine whether subsequent information can be read, if so, a management end check value and current management information are obtained, then the management end check value is checked, and only if the check is passed, the fact that the information is not tampered can be proved, and the safety of the information is ensured. Therefore, according to the method and the device, on one hand, whether the subsequent information can be read or not is judged through the second operation code, so that the efficiency is improved, and on the other hand, the information safety is guaranteed through verification.
Further, the sending the response message to the host management end includes: transmitting a response message to a host management end according to a preset time interval; correspondingly, the method further comprises the following steps: if the second operation code is not the second preset operation code, judging whether the second operation code is a third preset operation code or not; if the operation code is the third preset operation code, stopping sending the response message.
In this embodiment, a response message is sent to the host management end at each preset time interval, and when the second operation code of the received collection message is the third preset operation code, the host is characterized as having completed adding, and at this time, the message sent by the host is closed, and the host is considered as having been taken over by the host management end.
S202, generating a response message by utilizing host information according to the collected message;
s203, the response message is sent to the host management end, so that the host management end obtains host information according to the response message, and the host information is added to the cluster information.
