Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. 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.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The hot standby service cluster is network service equipment with a plurality of complete servers built therein, wherein each server can independently complete data storage and simultaneously operate; in the process of storing data from an external port, each server is independent in parallel; in the process of outputting data to an external network, the data is realized only through one of the servers, and when the server which is realizing the external output is in system error downtime, the port is rapidly switched, so that the service continuity is realized. In order to realize the availability of the system, the priority of the external port is set for each server in the server cluster, when the main service with high priority is down, the standby server with low priority enables the external port, and this leads to that the transfer of the data port is always from the main server to the standby server under normal conditions, so that in the case that the standby server is already operated, if the standby server is down, the standby server has no server with lower authority can be transferred, and therefore, the authority of the external port must be transferred back to the main server in time in the period that both the standby server and the main server are normally operated.
Fig. 1 is a schematic diagram of a method for transferring authority of a hot standby service cluster, which is provided in an embodiment of the present application, and is applied to a main server, where the hot standby service cluster includes a main server and a standby server that operate simultaneously; the main server and the standby server respectively comprise at least one monitor, and the number of monitors of the main server is smaller than that of the standby server;
the method may comprise the steps of:
step 101, acquiring a starting signal generated by the main server during restarting through a monitor of the main server.
In some embodiments of the present application, since the restart of the primary server may be caused by a fault or maintenance, etc., the monitor of the primary server may be utilized to timely know the operation state of the primary server.
For example, the monitor of the main server may include a generator of a start signal, which may be a hardware circuit or a software program, and its function is to generate a specific start signal, such as a digital code or a character string, according to a preset rule or condition when the main server is restarted, where the start signal may include information of identification information, restart time, restart reason, etc. of the main server, and send the start signal to the monitor of the main server, so that the monitor of the main server may determine the operation state of the main server according to the start signal and make corresponding feedback.
Step 102, responding to the starting signal, and sending a request signal to a monitor of the standby server through a monitor of the main server; the request signal is used for the standby server to feed back a response signal.
In some embodiments of the present application, in order to implement rights transfer for a hot standby service cluster, a monitor of a primary server needs to communicate with a monitor of a standby server to obtain feedback information of the standby server. Therefore, the monitor of the main server may send a request signal to the monitor of the standby server after receiving the start signal, and ask the monitor of the standby server to return a response signal to indicate the operation state and willingness of the standby server.
For example, a transmitter of a request signal may be disposed in the monitor of the main server, where the transmitter may be a hardware circuit or a software program, and its function is to generate a specific request signal, for example, a digital code or a character string, according to a preset rule or condition after the monitor of the main server receives the start signal, where the request signal may include information of identification information, a request type, a request time, etc. of the main server, and send the request signal to the monitor of the standby server through a network or other communication modes, so that the monitor of the standby server may determine the request content of the main server according to the request signal and make corresponding feedback.
Step 103, receiving response signals fed back by the monitor of the standby server according to the request signals, and counting the number of the received response signals; the response signals are in one-to-one correspondence with monitors of the standby server.
In some embodiments of the present application, in order to implement rights transfer for a hot standby service cluster, the monitor of the primary server needs to count feedback situations of the monitors of the standby servers. Therefore, after the monitor of the main server sends the request signal, the monitor of the standby server can receive the response signal returned by the monitor of the standby server and record the number of the received response signals to judge whether the target value is reached or not, so that the external port of the hot standby service cluster is determined to be the output port of the main server.
The monitor of the primary server comprises, for example, a receiver of the response signal and a counter, which may be a hardware circuit or a software program, the function of which is to receive the response signal returned by the monitor of the standby server after the monitor of the primary server has sent the request signal and store it in a buffer, while the value of the counter is incremented by one, indicating that a response signal has been received. When the number of received response signals is equal to or greater than the target value, the monitor of the primary server may determine that the monitor of the backup server has agreed to switch the external port to the output port of the primary server, and perform a corresponding operation.
Step 104, determining the external port of the hot standby service cluster as the output port of the main server under the condition that the counted number of the response signals is larger than a target value; the target value is half of the total number of monitors in the hot standby service cluster.
In some embodiments of the present application, in order to implement rights transfer of the hot standby service cluster, the monitor of the primary server needs to determine that the external port of the hot standby service cluster is the output port of the primary server. Therefore, the monitor of the main server can modify the network configuration of the hot standby service cluster under the condition that the number of the counted response signals is larger than the target value, and switch the external port from the output port of the standby server to the output port of the main server, so that the main server recovers the capability of providing service to the outside; meanwhile, as the number of monitors of the main server is smaller than that of the standby servers, the response signals obtained by the main server are larger than half of the total number of monitors in the hot standby service cluster, so that the main server authority can be ensured to be obtained.
The monitor of the main server includes a network configurator, which may be a hardware circuit or a software program, and functions to send an instruction to the load balancer or the reverse proxy of the hot standby service cluster through a network or other communication modes, where the number of response signals counted by the monitor of the main server is greater than a target value, to switch the external port from the output port of the standby server to the output port of the main server, so that the main server becomes a working machine of the hot standby service cluster, and the standby server becomes a backup machine of the hot standby service cluster.
In summary, in the embodiment of the present application, a monitor of a main server acquires a start signal generated when the main server is restarted, and sends a request signal to a monitor of a standby server, so that the standby server can timely feed back a response signal; and receiving and counting the number of the response signals through a monitor of the main server to judge whether the target value is reached or not, thereby determining that the external port of the hot standby service cluster is an output port of the main server. Therefore, according to the method, after the main server is stopped and restarted, the permission transfer of the hot standby service cluster can be realized, the problem that the main server cannot be called after the standby server is stopped, and network service cannot be continuously used is avoided, the reliability and stability of the hot standby service cluster are improved, and the time and cost of fault recovery are reduced.
As shown in fig. 2, corresponding to steps 101 to 104, the embodiment of the present application further provides a rights transferring method of a hot standby service cluster, which is used for a standby server, where the hot standby service cluster includes a main server and a standby server that operate simultaneously; the main server and the standby server respectively comprise at least one monitor, and the number of monitors of the main server is smaller than that of the standby server;
The method may comprise the steps of:
step 201, obtaining a request signal sent by a monitor of a main server through the monitor of the standby server; the request signal is generated by a monitor of the main server according to the acquired starting signal generated by the main server during restarting.
In some embodiments of the present application, in order to implement rights transfer for a hot standby service cluster, a monitor of a standby server needs to acquire a request signal sent by a monitor of a primary server. Therefore, the monitor of the standby server may monitor the output of the monitor of the main server through a network or other communication means, so as to capture the request signal sent by the monitor of the main server in time.
For example, the monitor of the standby server may include a receiver of the request signal, where the receiver may be a hardware circuit or a software program, and its function is to connect, through a network or other communication means, to an output port of the monitor of the main server after the monitor of the standby server is started, so as to receive the request signal sent by the monitor of the main server. When the monitor of the standby server receives the request signal, the request type and the request time of the monitor of the main server can be judged according to the content of the request signal, and corresponding feedback is made.
Step 202, responding to the request signal, and sending a response signal to the monitor of the main server through the monitor of the standby server; the answer signal is used for being received by the monitor of the main server and counting the number, so that the external port of the hot standby server cluster is determined to be the output port of the main server under the condition that the number of the answer signal is larger than a target value; the target value is half of the total number of monitors in the hot standby service cluster.
In some embodiments of the present application, in order to implement rights transfer for a hot standby service cluster, the monitor of the standby server needs to send a reply signal to the monitor of the primary server. Therefore, after receiving the request signal sent by the monitor of the main server, the monitor of the standby server can generate a specific response signal according to the running state and wish of the monitor of the main server, and send the response signal to the monitor of the main server through a network or other communication modes, so that the monitor of the main server can receive and count the number of the response signals to judge whether the number reaches the target value or not, thereby determining that the external port of the standby service cluster is the output port of the main server.
For example, the monitor of the standby server may include a transmitter of a response signal, where the transmitter may be a hardware circuit or a software program, and its function is to generate a specific response signal, such as a digital code or a character string, according to a preset rule or condition after the monitor of the standby server receives the request signal, where the response signal may include information of identification information, response type, response time, etc. of the standby server, and send the response signal to the monitor of the main server through a network or other communication modes, so that the monitor of the main server may determine a feedback condition of the monitor of the standby server according to the response signal, and perform a corresponding operation.
Corresponding to the process of transferring rights on the side of the main server, the monitor on the side of the standby server can be designed to be identical to the operating mechanism of the monitor on the side of the main server, and the mechanism does not affect the process of transferring rights, because: the number of monitors on the main server side is different from that of monitors on the standby server side, and the number of monitors on the main server side is smaller than that of monitors on the standby server side, and the design mechanism can ensure that response signals acquired by the monitors on the main server side always exceed half of the total monitors in the standby cluster, so that the condition of server output port permission transfer caused by restarting of the standby server in the running state of the main server is not generated.
FIG. 3 is a schematic diagram of another authority transfer method of a hot standby service cluster according to an embodiment of the present application, where the hot standby service cluster is applied to a primary server, and includes a primary server and a standby server that operate simultaneously; the main server and the standby server respectively comprise at least one monitor, and the number of monitors of the main server is smaller than that of the standby server;
step 301, acquiring a starting signal generated by the main server during restarting through a monitor of the main server.
The method shown in this step is already described in step 101, and will not be described here again.
Step 302, responding to the starting signal, and sending a request signal to a monitor of the standby server through a monitor of the main server; the request signal is used for the standby server to feed back a response signal.
The method shown in this step is already described in step 102, and will not be described here again.
Optionally, the step 302 includes the following sub-steps:
sub-step 3021, determining a network address of a monitor of the standby server.
In some embodiments of the present application, in order to enable rights transfer for a hot standby service cluster, the monitor of the primary server needs to know the network address of the monitor of the standby server in order to send a request signal thereto. Thus, the monitor of the primary server may send a query signal to the monitor of the backup server at startup or periodically via a network or other communication means, asking it to return information about its own network address, e.g., physical address, port number, etc.
The monitor of the main server includes a transmitter of a query signal and a receiver of a network address, which may be a hardware circuit or a software program, and functions to generate a specific query signal, such as a digital code or a character string, according to a preset rule or condition when the monitor of the main server is started, where the query signal may include information of identification information, query type, query time, etc. of the main server, and send the query signal to the monitor of the standby server through a network or other communication modes, so that the monitor of the standby server may determine the query content of the monitor of the main server according to the query signal and make corresponding feedback. When the monitor of the primary server receives the network address returned by the monitor of the backup server, it can be stored in a buffer for use when needed.
Sub-step 3022, sending a request signal to each of said monitors of the standby server, respectively, based on said network address.
In some embodiments of the present application, in order to implement rights transfer for a hot standby service cluster, the monitor of the primary server needs to send a request signal to each monitor of the standby server separately. Therefore, after determining the network address of the monitor of the standby server, the monitor of the main server may generate a corresponding number of request signals according to the number of network addresses, and send each request signal to the monitor of the corresponding standby server through a network or other communication modes, so that each monitor of the standby server may determine the request content of the monitor of the main server according to the received request signals, and make corresponding feedback.
For example, the monitor of the main server may include a generator of a request signal and a distributor of the request signal, where the generator and the distributor may be a hardware circuit or a software program, and the function of the generator and the distributor is to generate a corresponding number of request signals, such as a digital code or a character string, according to the number of network addresses after the monitor of the main server determines the network addresses of the monitors of the standby server, where each request signal may include identification information of the main server, a request type, a request time, and other information, and send each request signal to the corresponding monitor of the standby server through a network or other communication modes, so that each monitor of the standby server may determine the request content of the monitor of the main server according to the received request signal and make corresponding feedback.
Step 303, receiving response signals fed back by the monitor of the standby server according to the request signals, and counting the number of the received response signals; the response signals are in one-to-one correspondence with monitors of the standby server.
The method shown in this step is already described in step 103, and will not be described here again.
Step 304, obtaining backup data from the backup database.
In some embodiments of the present application, to enable rights transfer for a hot standby service cluster, a monitor of a primary server needs to obtain standby data from a standby database. Thus, the monitor of the primary server may send a data acquisition signal to the standby database via a network or other communication means requesting it to return all of the standby data, i.e., all of the data stored in the standby database, before the update of the data in the primary database is completed.
The monitor of the main server includes a transmitter of a data acquisition signal and a receiver of backup data, which may be a hardware circuit or a software program, and functions to generate a specific data acquisition signal, such as a digital code or a character string, before the monitor of the main server completes updating the data in the main database, where the data acquisition signal may include information such as identification information, data acquisition type, data acquisition time, etc. of the main server, and send the data acquisition signal to the backup database through a network or other communication modes, so that the backup database may determine the data acquisition content of the monitor of the main server according to the data acquisition signal, and make corresponding feedback. When the monitor of the primary server receives all the backup data returned by the backup database, it may be stored in a buffer for subsequent processing.
