Description
Technical Field
The invention relates to the technical field of computers, in particular to a method, a device, a medium and equipment for avoiding network service dual-computer hot standby brain cracking.
Background
A high availability Cluster, in english, high Availability Cluster, HA Cluster for short, is simply a group of computers that as a whole provide a set of network resources to the user. These individual computer systems are the nodes of the cluster. A high availability cluster (HA cluster) refers to a cluster of hosts that operate as a single system and support (computers) continuous normal operation.
The high availability clusters are presented in order to make the overall service of the clusters as available as possible, thereby reducing the loss caused by computer hardware and software error-prone. If a node fails, its standby node will take care of its duties within a few seconds. Thus, the cluster is never down for the user. The main role of highly available cluster software (e.g. keepalive) is to automate the fault checking and service switching.
A high availability cluster with only two nodes is also called a dual hot standby, i.e. two servers are used to back up each other. When one server fails, the other server can bear the service task, so that the system can be automatically ensured to continuously provide service to the outside without manual intervention. Dual hot standby is one of the highly available clusters.
As shown in fig. 1, service cluster a and service cluster B are dual hot standby, and a and B negotiate a master-standby state through a jumper connection. The data traffic of the service is sent to the service cluster a in the master state.
User access process:
the user requests access to the service of ip address 10.0.0.1, and the server with 10.0.0.1 ip returns the information accessed by the user.
The procedure for the next heartbeat is described here:
the system comprises a server A and a server B, wherein the server A and the server B select the state A as a main state (through priority judgment) through the interactive information of the cardiac jumper. Then the A server with the main state announces the ip address of 10.0.0.1 to the front-end switch, and after the flow passes through the front-end switch, the switch sends the flow to the server A.
The main state server A periodically issues heartbeat messages through heartbeat lines, informs the outside of the current self priority, and the machine B in the standby state keeps the current state when monitoring that the priority of the heartbeat messages sent by the server A is greater than or equal to the priority of the heartbeat messages sent by the server A. When the machine A in the main state goes wrong, service cannot be provided (if a program dies), the priority of the machine B is regulated to send out a heartbeat message, or the heartbeat message cannot be issued (the machine is hung up, or a local network port is not connected), the standby state machine receives the heartbeat message with lower priority than the machine B, or the standby state machine does not receive the heartbeat message for a certain time, actively sends the heartbeat message including the priority of B, after the heartbeat message with higher priority than the machine B is not received in fixed time, the machine B announces the machine B is in the main state, then announces the IP of 10.0.0.1 to a switch at the front end, and a message of a user accessing the IP is sent to the server B through the switch.
As shown in fig. 2, the cause of the brain fracture of the network service dual hot standby is shown, and in a High Availability (HA) system, when the "cardiac jumper" connecting 2 nodes is disconnected, the HA system, which is an integral and coordinated action, is split into 2 independent individuals. The other side fails because of losing contact with each other. The HA software on the two nodes is similar to "split brain" and HAs serious consequences, namely, the 2-side "service" is all up, the service ip is issued to the outside, one ip session flow of the user accessing the service may be respectively issued to the two nodes, and the stateful session causes failure.
At present, the cerebral infarction solving mode
Countermeasures against "split brain" of the HA system are currently agreed on:
1) Redundant heartbeat lines are added, for example: double line (heart beat line is HA) to reduce occurrence probability of split brain; as shown in fig. 3, by adding redundant heartbeat lines, the problem of brain cracking existing in the network service dual-computer hot standby is solved; however, as shown in fig. 3, the problem of brain fracture cannot be solved, but the risk of brain fracture is reduced, and additional network card equipment is also required.
2) An arbitration mechanism is set. For example, a reference IP (such as gateway IP) is set, when the cardiac jumper is completely disconnected, each of the 2 nodes pings the reference IP, and if not, a breakpoint is indicated to be at the home terminal. The network link of the local terminal which is not only the heartbeat but also the external service is broken, and even if the application service is started (or continued) is not used, the competition is actively abandoned, so that one end of the reference IP can be pinged to start the service. More insurance, a party that does not refer to IP simply reboots itself to completely free up shared resources that might otherwise be occupied. As shown in fig. 4, an arbitration mechanism is set to solve the problem of network dual-machine hot standby brain-splitting, as shown in fig. 4, a heart jumper of a server B is broken, and the server B also pings off a third-party gateway, so that the server a is in a main state. The method for solving the problem of network double-machine hot-standby brain cracking by setting a blanking mechanism has the following defects: additional network ports are needed, and the cost is high; in addition, the flow of third party arbitration is added, and the scheme becomes complex. Therefore, in long-term research and development, the inventor has conducted a great deal of research on how to avoid the network service dual-computer hot standby split, and put forward a method for avoiding the network service dual-computer hot standby split to solve one of the above technical problems.

Example 1
Fig. 5 is a schematic diagram of a data channel and a cardiac jumper set in a method for avoiding network service dual-standby brain burst according to an embodiment of the present invention.
As shown in fig. 5, the method provided by the present invention allows the traffic flowing on the jumper to flow on the original data link.
The first jumper of the first server cluster is arranged on a first data link of the first server cluster; the second jumper wire of the second server cluster is arranged on a second data link of the second server cluster; therefore, no extra physical resource related to the heartbeat line is needed, no third party is introduced for arbitration, logic simplicity can be kept, and the possibility of external service while cerebral rupture is completely avoided.
As shown in fig. 6, according to a specific embodiment of the present disclosure, in a first aspect, the present disclosure provides a method for avoiding a network service dual hot standby brain burst, which specifically includes the following method steps:
s602: the first jumper of the first server cluster is arranged on a first data link of the first server cluster; and a second jumper of the second server cluster is arranged on a second data link of the second server cluster.
In the step, the flow running on the heartbeat line runs on the original data link, so that additional physical resources related to the heartbeat line are not needed, and a third party is not needed to be introduced for arbitration, the logic is kept simple, and the possibility of external service while cerebral rupture is completely avoided.
S604: and receiving a first vrrp heartbeat message sent by the first server cluster and a second vrrp heartbeat message sent by the second server cluster.
In this step, vrrp (virtual router redundancy protocol, virtual routing redundancy protocol) is a routing protocol proposed by IETF to solve the problem of single point failure of a static gateway configured in a local area network, and the standard of the RFC2338 protocol has been proposed in 1998. VRRP is widely used in edge networks, and its design goal is to support IP data traffic failover without confusion in certain situations, allow hosts to use single routers, and maintain connectivity between routers in the event of failure of the actual first-hop router.
S606: and analyzing the first vrrp heartbeat message and the second vrrp heartbeat message according to a preset rule, and selecting a server cluster serving as a main state from the first server cluster and the second server cluster so as to facilitate the server cluster in the main state to advertise the network service ip.
In this step, according to a preset rule, the first vrrp heartbeat message and the second vrrp heartbeat message are analyzed, so that the server cluster serving as the main state can be precisely selected from the first server cluster and the second server cluster.
The method provided by the invention can accurately determine the server cluster in the main state from the first server cluster and the second server cluster, and announce the network service ip through the determined server cluster in the main state.
As shown in fig. 7, a flowchart of a method for electing a server cluster as a master state from a first server cluster and a second server cluster and advertising an ip address in a specific application according to an embodiment of the present invention is shown.
From the flowchart shown in fig. 7, it can be known that: after receiving the message, the server distinguishes the flow requested by the user from the flow of the heartbeat message.
Under different application scenarios, the destination ip of the heartbeat message is ip with a fixed value.
In a specific application scene, the destination ip of the heartbeat message is the ip of the vrrp protocol with a fixed value; for example, the destination ip address anchor address of the vrrp protocol is 224.0.0.18.
The server A and the server B elect a main state server by sending a vrrp heartbeat message with the destination ip of 224.0.0.18, and then announce ip 10.0.0.1 to the outside.
In this specific application scenario, the server a may be a first server cluster or a second server cluster; server B may be a first server cluster or a second server cluster.
In addition, the method provided by the invention can also switch the server cluster in the main state, and the first server cluster is the main server cluster within the time set by a certain timer; and the second server cluster is the main server cluster in the time set by another timer.
Optionally, a first jumper in the first server cluster is disposed on a first data link of the first server cluster; and after the second heartbeat line of the second server cluster is disposed on the second data link of the second server cluster, the method further includes:

Optionally, a first jumper in the first server cluster is disposed on a first data link of the first server cluster; and after the second heartbeat line of the second server cluster is disposed on the second data link of the second server cluster, the method further includes:
receiving a second message of the second server cluster, analyzing the received second message, judging whether the second message is an ip message, judging whether the second message is a heartbeat message according to a destination ip corresponding to the second message after judging that the second message is the ip message, and if the destination ip corresponding to the second message is a preset fixed value, judging that the second message is a second heartbeat message of the second server cluster; otherwise, if the destination ip corresponding to the second message is not the preset fixed value, the second message is the ip message requested by the user.
Optionally, electing a server cluster from the first server cluster and the second server cluster as the master state includes:
judging whether the priority of the first heartbeat message of the first server cluster is greater than or equal to the priority of the first heartbeat message, if the priority of the first heartbeat message of the first server cluster is smaller than the priority of the first heartbeat message, further judging whether the first server cluster is in a main state, and if the first server cluster is in the main state, determining to elect the first server cluster from the first server cluster and the second server cluster as the server cluster in the main state.
Optionally, after electing the first server cluster as the server cluster of the master state, the method further comprises:
and periodically sending a first heartbeat message of the first server cluster.
Optionally, after electing the first server cluster as the server cluster of the master state, the method further comprises:

Optionally, electing a server cluster from the first server cluster and the second server cluster as the master state further includes:
judging whether the priority of the first heartbeat message of the first server cluster is greater than or equal to the priority of the first heartbeat message, if the priority of the first heartbeat message of the first server cluster is greater than the priority of the first heartbeat message, further judging whether the first server cluster is in a main state, and if the first server cluster is in the main state, modifying the main state of the first server cluster into an alternative state; otherwise, if the first server cluster is judged not to be in the master state, the timer is canceled.
Referring to fig. 8, another method flowchart for avoiding network service dual hot standby brain cracking is shown according to an embodiment of the present invention.
As shown in fig. 8, when the server B is disconnected from the line of the switch, the heartbeat line is disconnected, and the data line is also disconnected. The heartbeat line is disconnected, and the servers A and B can not negotiate and can all become a main state, but because the line of the server B is disconnected, the server B can not announce the IP to the outside, and the flow of the exchanger can only be transferred to the server A. The user's traffic will not be sent to both devices and no interruption will occur.
