As shown in fig. 1, the implementation scenario 100 includes: client 110, load balancer 120, and server 130, server 131, server 132, and server 133.
The client 110 may be a terminal device. For example, the client 110 may be a mobile phone, a tablet computer, a laptop portable computer, or a desktop computer. That is, the client 110 may select a specific type of the client 110 according to actual needs, and the embodiment of the present application is not limited thereto. The client 110 is provided with communication capabilities and may run a browser or other application capable of loading and displaying web pages. For example, the application program may be a conference management application, a social application, an office application, or the like.
In this embodiment of the present application, when the load balancer 120 receives an access request sent by a client 110 and carrying an IP address of the client 110, the load balancer 120 determines whether the IP address of the client 110 meets a preset access condition, if so, the load balancer 120 obtains operator information of a region and a network operator where the client 110 is located according to the IP address, and when the operator information of the region and the network operator where the client 110 is located do not meet a preset IP address transfer condition, the load balancer 120 determines a target server (that is, the server 130, the server 131, the server 132, and the server 133, and the number of servers may be set according to actual requirements) corresponding to the region and the network operator information where the client 110 is located according to the obtained parameter information of a plurality of servers (that is, the server 130, the server 132, and the server 133) according to actual requirements, Server 131, server 132, or server 133). The load balancer 120 obtains a target IP address of the target server (i.e. may be the server 130, the server 131, the server 132, or the server 133), and the load balancer 120 sends the target IP address of the target server (i.e. may be the server 130, the server 131, the server 132, or the server 133) to the client 110, so that the client 110 accesses the target server according to the received target IP address.
Fig. 1 is a schematic flowchart of a cluster scheduling method provided in an embodiment of the present application, where the method is applied to a load balancer, and specifically includes the following steps:
s101, receiving an access request which is sent by a client and carries an IP address of the client.
The embodiment of the application provides a multi-level and bidirectional-connection cluster scheduling scheme, which comprises the following three parts: 1. the dangerous IP addresses are shielded, and the load balancer can shield specific client access according to the IP addresses or IP sections by configuring a blacklist, so that the cluster is prevented from being attacked by external traffic; 2. according to the region where the client is located and the operator information of a network operator, a specific back-end server (for example, an overseas server arranged in an overseas machine room) is assigned to the client; 3. and dynamically scheduling, namely reporting parameter information of the server to the load balancer at regular time by a back-end server (namely an entity server), wherein the parameter information comprises indexes such as CPU (Central processing Unit) occupancy rate, memory occupancy rate, idle network bandwidth and the like, and the back-end server with the minimum load can be selected by the load balancer to perform scheduling according to a custom algorithm in the operation process.
S102, when the IP address of the client meets the preset access condition, acquiring the operator information of the area where the client is located and the network operator according to the IP address.
In the following, whether the IP address of the client meets the preset access condition is determined through the following two ways, and those skilled in the art should know that whether the IP address of the client meets the preset access condition may also be determined through other ways.
In a first way,
Matching the IP address of the client with an IP address database, wherein a plurality of preset IP addresses and preset IP segment address sets which are forbidden to access are stored in the IP address database;
when the IP address of the client is not matched with any preset IP address which is forbidden to be accessed in the IP address database and the preset IP section address set, determining that the IP address of the client meets a preset access condition;
and when the IP address of the client is matched with the preset IP address which is forbidden to be accessed and the preset IP segment address set in the IP address database, determining that the IP address of the client does not meet the preset access condition, and forbidding the processing of the access request of the client.
According to the embodiment of the application, the IP address blacklist, namely the multiple access-prohibited preset IP addresses and the preset IP section address set, is stored in the cache of the load balancer through the active defense mechanism, the active defense mechanism is configured by an operator, when the operator monitors that a client side has certain malicious behaviors, the operator can add a single IP address or a certain IP section into the blacklist, the IP address or the IP section in the blacklist is shielded when the client side accesses the front-end load balancer and cannot acquire a rear-end server, so that the server cluster is prevented from being attacked by external traffic, and high availability of the cluster is guaranteed.
The second way,
Acquiring the access frequency of the IP address of the client in unit time;
when the access frequency does not exceed a preset access frequency threshold, determining that the IP address of the client meets a preset access condition;
and when the access frequency exceeds a preset access frequency threshold, determining that the IP address of the client does not meet a preset access condition, and prohibiting processing of the access request of the client.
For example, the access frequency threshold is set to 30, the unit time is set to a single day, and when the access frequency of an IP address of a certain client in the single day is 35, the access frequency of the client exceeds the access frequency threshold, it is determined that the client does not satisfy the preset access condition, and the processing of the access request of the client is prohibited; if the access frequency of the IP address of a certain client in a single day is 20, the access frequency of the client does not exceed the access frequency threshold, and the preset access condition is met.
In the embodiment of the application, through the passive defense mechanism, a single IP address or a single-day access frequency of a certain IP segment is monitored and limited by a program, and in this type of monitoring mode, 1 counter is stored in a load balancer cache, so that when the single-day access count of the certain IP address or the certain IP segment reaches an access frequency threshold, the front-end load balancer shields the IP address or the IP segment and limits the IP address or the IP segment from accessing a back-end server again.
According to the cluster scheduling method and the cluster scheduling system, by combining two different defense modes, namely an active defense mechanism and a passive defense mechanism, a barrier can be arranged in a load balancer at the forefront end, a rear-end server is protected from flow attack, dangerous clients are shielded by an operator through a configuration mode through the active defense mechanism, the clients with too high access times are automatically subjected to frequency limitation through a program through the passive defense mechanism, cluster health can be guaranteed, and high availability of a cluster is guaranteed.
S103, when the region where the client is located and the operator information of the network operator do not accord with the preset IP address transfer condition, determining a target server corresponding to the region where the client is located and the network operator information according to the acquired parameter information of the plurality of servers.
Optionally, it is determined whether the operator information of the area where the client is located and the network operator meets a preset IP address transfer condition in the following manner:
matching the operator information of the area where the client is located and the network operator with an IP address transfer database, wherein the IP address transfer database stores a plurality of preset areas, the operator information of preset network operators and preset IP addresses of preset servers corresponding to the operator information of the preset areas and the preset network operators, and the preset servers comprise overseas servers;
when the operator information of the network operator and the preset region of the preset IP address to be transferred in the IP address transfer database are not matched with the operator information of the preset network operator and the preset region of the preset IP address to be transferred, determining that the operator information of the network operator and the region where the client is located do not accord with the preset IP address transfer condition;
when the operator information of the network operator and the area where the client is located are matched with the operator information of the preset network operator and the preset area of the preset IP address to be transferred in any one of the IP address transfer databases, determining that the operator information of the network operator and the area where the client is located accord with the preset IP address transfer condition;
acquiring a preset IP address of the overseas server corresponding to the region where the client is located and the operator information of the network operator;
and sending the preset IP address of the overseas server to the client so that the client accesses the overseas server according to the received preset IP address.
Optionally, because there are many overseas users of some clusters, when a cluster is deployed, because the speed of accessing an in-ground server by an overseas user is low, a part of servers often need to be deployed in an overseas machine room, and a client initiating access to the cluster from a certain region or an operator network is specified to be able to obtain an optimal server. The embodiment of the application specifies that a client initiating access to a cluster from a certain area or an operator network can acquire an optimal server, and the implementation principle is as follows:
an IP address forwarding list, i.e. the above-mentioned IP address forwarding database, is configured in the load scheduler, and for example, the IP address forwarding list is defined as: region/operator- [ IP address of server ], for example: taiwan- [49.0.0.1,49.0.0.2] or china mobile hong kong- [49.0.0.3,49.0.0.4 ]. When a client of a user needs to access a back-end server, the client carries an IP address of the client to access a load balancer, the load balancer acquires the IP address of the client, acquires the information of an area where the client is located and an operator of a network operator, checks whether the area where the client of the user is located or the operator is in a transfer list, if so, assigns a specific overseas server to the user, otherwise, enters a dynamic scheduling step, determines a target server corresponding to the information of the area where the client is located and the network operator, optimizes the network access of the specific area and the network operator, can configure a request initiated from the specific area or the specific operator, and when a certain area or the operator is slow to access some back-end servers in cluster operation, an operator can configure the transfer list to assign the back-end servers, the user experience is improved.
Optionally, the parameter information of the server includes one or more of the following: CPU occupancy, memory occupancy, and free network bandwidth.
After the cluster is started, operator information of a machine room where each server is located is stored in the load balancer; when the cluster runs, the server regularly reports the current state to the load balancer according to a fixed time interval (for example, set to 5 seconds), that is, parameter information of the server is sent, including but not limited to CPU occupancy, memory occupancy, idle network bandwidth, and the like. The load balancer receives and stores the parameter information reported by all the servers in the memory, and sorts the servers according to a certain scheduling algorithm, for example, according to the priority of the lowest CPU occupancy rate.
When a client of a user needs to access a back-end server, the client carries an IP address of the client to access the load balancer, and after the load balancer acquires the IP address of the client, the load balancer returns a server which is the same as an operator and is ranked the most front to the user according to the acquired operator information of a network operator where the client is located, so that the dynamic scheduling of the cluster can be realized.
In the embodiment of the application, the load balancer schedules the back-end server, and the back-end server reports the state to the load balancer, so that the client can be ensured to acquire the optimal server information, the servers with high load and the servers with abnormal states can be eliminated by the load balancer, and the servers with high load and the servers with abnormal states can not receive the access requests of the user; after the load of the server is reduced or recovered from the abnormal state, the parameter information of the server can be continuously reported to the load balancer to continuously provide service, so that the dynamic scheduling of the cluster can be ensured, and the fault-tolerant capability is strong.
S104, acquiring the target IP address of the target server.
S105, sending the target IP address of the target server to the client, so that the client accesses the target server according to the received target IP address.
According to the embodiment of the application, the rear-end server can be dynamically scheduled according to the cluster load through a multi-level cluster scheduling scheme, a defense mechanism is established, access of dangerous IP addresses can be shielded, high availability of clusters is guaranteed, network access of specific regions and network operators is optimized, and user experience is improved.
Fig. 2 is a schematic flowchart of another cluster scheduling method provided in the embodiment of the present application, where the method is applied to a load balancer, and specifically includes the following steps:
s201, receiving an access request which is sent by a client and carries an IP address of the client.
S202, when the IP address of the client meets the preset access condition, acquiring the operator information of the area and the network operator where the client is located according to the IP address.
S203, when the region where the client is located and the operator information of the network operator do not accord with the preset IP address transfer condition, the server is subjected to priority sequencing through a corresponding scheduling algorithm according to the parameter information of the server.
For example, the CPU occupancy rate of each server is obtained, and the server with the lowest CPU occupancy rate is selected as the server with the highest priority; for another example, the memory occupancy rate of each server is obtained, and the server with the lowest memory occupancy rate is selected as the server with the highest priority.
S204, according to the sequencing order, the server with the highest priority is screened out from the servers.
S205, taking the server with the highest priority as the target server.
S206, acquiring the target IP address of the target server.
S207, sending the target IP address of the target server to the client, so that the client accesses the target server according to the received target IP address.
According to the embodiment of the application, the servers are subjected to priority ranking according to the parameter information of the servers, and the server with the high priority is selected as the target server, so that the service processing speed can be increased, and the stable operation of the system can be guaranteed.
