If so, then switching device according to preset rules, can safeguard that the priority of its corresponding redis is constant or incites somebody to action
The priority of its corresponding redis is raised, so that the priority of its corresponding redis is more than other redis in redis systems
Priority.
If it is not, then switching device according to preset rules, can safeguard that the priority of its corresponding redis is constant or incites somebody to action
The priority of its corresponding redis is reduced so that the priority of its corresponding redis less than in redis systems main redis it is excellent
First level.
If the priority of the corresponding redis of S203, switching device is more than the priority of other redis in redis systems,
The mapping relations of the IP address of the virtual ip address redis corresponding with switching device of redis systems are set, so that business network element
The corresponding redis of switching device is accessed by the virtual ip address of redis systems.
After priority update of the switching device to its corresponding redis, switching device obtains other in redis systems
The priority of redis, optionally, the switching device can switching device corresponding with other redis communicated, to obtain other
The priority of redis.
Switching device judge the priority of its corresponding redis whether more than in redis systems other redis it is preferential
Level, if so, then in redis systems, the highest priority of the corresponding redis of the switching device illustrates that the redis is redis systems
Main redis in system.
Switching device judges
It is no with mapping relations.Wherein, when between the IP address of the virtual ip address of redis systems redis corresponding with switching device
During with mapping relations, then business network element can access the corresponding redis of switching device according to virtual ip address.
If having mapping relations between the IP address of the virtual ip address of redis systems redis corresponding with switching device,
Then switching device need not perform other operations.
If not having mapping to close between the IP address of the virtual ip address of redis systems redis corresponding with switching device
It is that then switching device will arrange the mapping pass of the IP address of the virtual ip address redis corresponding with switching device of redis systems
System.Optionally, switching device can set up the virtual ip address of the corresponding redis of switching device, and switching device is corresponding
The virtual ip address of redis is defined as the virtual ip address of redis systems.
If the priority of the corresponding redis of S204, switching device less than or equal in redis systems other redis it is excellent
First level, then it is determined that the IP address of the virtual ip address of redis systems redis corresponding with switching device has mapping relations
When, cancel mapping relations.
Whether switching device judges the priority of its corresponding redis less than or equal to other redis in redis systems
During priority, illustrate that the corresponding redis of switching device is not the main redis of redis systems.Switching device is determined whether
Whether there are mapping relations between the IP address of the virtual ip address of redis systems redis corresponding with switching device.
If judge not have between the IP address of the virtual ip address of redis systems redis corresponding with switching device reflecting
Relation is penetrated, then switching device need not perform other operations.
If judging that there is between the IP address of the virtual ip address of redis systems redis corresponding with switching device mapping
Relation, then switching device cancel the mapping relations, to avoid business network element redis corresponding to switching device from conducting interviews.Can
Choosing, switching device can delete the redis, and redis systems virtual ip address identical IP address.
The master-slave switching method of redis provided in an embodiment of the present invention, it is corresponding by each redis in redis systems
Switching device is safeguarded to the IP address of redis, when a redis is the main redis in redis systems, this redis pair
The switching device answered arranges the corresponding relation of the redis and the virtual ip address of redis systems, so that business network element can basis
The virtual ip address of redis systems, conducts interviews to the main redis of the redis systems.In above process, when entering to redis
After row master-slave swap, only the IP address of redis in redis systems need to be updated, without the need for each service network
Unit sends a notification message, and the IP address of the main redis of redis systems is modified by business network element, simplifies to redis
The process of master-slave swap is carried out, and then improves the efficiency that middle switching is carried out to redis.
In the embodiment shown in Figure 2, optionally, mark of the following feasible implementation according to main redis can be passed through
Know, update the priority (S202 in embodiment illustrated in fig. 2) of the corresponding redis of switching device, specifically, refer to Fig. 3 institutes
The embodiment shown.
The schematic flow sheet of the renewal redis priority approach that Fig. 3 is provided for the present invention.Refer to Fig. 3, the method can be with
Including：
S301, the mark for judging main redis redis corresponding with switching device identify whether it is consistent；
If so, then perform S302.If it is not, then performing S303.
When switching device judges that the mark of the mark of main redis redis corresponding with switching device is consistent, switching device
Determine its corresponding redis be redis systems main redis, then need the priority for safeguarding its corresponding redis it is constant, or
The priority of its corresponding redis is raised by person, so that the priority of its corresponding redis is more than other in redis systems
The priority of redis.
When switching device judges that the mark of the mark of main redis redis corresponding with switching device is inconsistent, switching dress
Put and determine that its corresponding redis is redis systems from redis, then need the priority for safeguarding its corresponding redis it is constant,
Or the priority of its corresponding redis is reduced, so that the priority of its corresponding redis is less than or equal to redis systems
The priority of middle main redis.
S302, by the priority update of switching device corresponding redis for the corresponding redis of switching device initial priority
Level and priority delta sum, initial priority and the priority delta sum of the corresponding redis of switching device are more than redis systems
The priority of other redis in system.
In the embodiment shown in fig. 3, each redis one initial priority of correspondence in redis systems, this is initial
Priority can be that operation personnel is arranged for each redis in deployment redis systems.Optionally, in operation personnel portion
During administration's redis systems, operation personnel can configure the main redis in redis systems and from redis, and arrange the first of main redis
Beginning priority is higher than the initial priority from redis.For example, it is assumed that operation personnel is when redis systems are disposed, redis systems
Include 3 redis, be designated as redis1-redis3 respectively, it is further assumed that operation personnel by redis1 arrange based on redis, will
Redis2 and redis3 are set to from redis, then the initial priority of redis1 can be set to 100 by operation personnel, will
The initial priority of redis2 and redis3 is set to 90.
Certainly, when operation personnel disposes redis systems, operation personnel can be with the initial priority according to main redis
With from redis initial priority arrange priority delta, wherein, priority delta more than main redis initial priority with
From the difference of the initial priority of redis.For example, it is assumed that the initial priority of main redis is 100, from the initial priority of redis
For 90, then priority delta is more than 10 (100-90), and for example, priority delta can be 20,30,50 etc..
When switching device judges that the mark of the mark of main redis redis corresponding with switching device is consistent, switching device
Obtain the initial priority and priority delta of its corresponding redis, and by the priority of switching device corresponding redis more
The new initial priority for the corresponding redis of switching device and priority delta sum.So, the switching device is corresponding
Priority of the priority of redis more than other redis in redis systems.
S303, by the priority update of switching device corresponding redis for the corresponding redis of switching device initial priority
Level.
When switching device judges that the mark of the mark of main redis redis corresponding with switching device is inconsistent, switching dress
Put by the priority update of its corresponding redis for the corresponding redis of switching device initial priority.
In above process, by arranging initial priority and priority delta for each redis in redis systems,
And the priority of each redis in redis systems is safeguarded using said method, so, in each switching device
During safeguarding to the priority of its corresponding redis, it is ensured that in redis systems, the priority of main redis is most
Height, and then can ensure that accurate master-slave swap is carried out to redis.
On the basis of above-mentioned any one embodiment, optionally, in actual application, in order to ensure switching device
Superperformance, it may be necessary to the operation such as periodically carry out upgrading to switching device, safeguard.Being updated to switching device,
When safeguarding, need to suspend switching device, suspended to switching device input from operation personnel when usual and notified.As switching device is needed
The IP address of redis is managed, when switching device is suspended, then the IP address of redis cannot be managed, be made
The IP address for obtaining the redis cannot be corresponding with the virtual ip address of redis systems, causes the redis then cannot be by business network element
Access, however, now, if the redis is the main redis of redis systems, access of the business network element to redis systems fails.
In order to avoid the generation of the problems referred to above, after switching device receives time-out notice, switching device is according to master
The mark of redis, judge the corresponding redis of switching device whether based on redis, if so, then suspend switching device corresponding
Redis, so that redis systems switch main redis.Certainly, after in order to avoid being suspended in switching device, the switching device pair
Redis based on the monitored module settings of redis answered, after switching device receives time-out notice, switching device can be straight
Connect and suspend the corresponding redis of the switching device.Optionally, after switching device receives time-out notice, can call
Stopmasterredis.sh scripts, so that redis is suspended by stopmasterredis.sh scripts.
On the basis of above-mentioned any one embodiment, optionally, in the running of redis, redis because of
Many reasons operation suspension, for example, it may be possible to due to the temporary load too high of redis, and cause redis operation suspensions.In reality
In the application process of border, in order to ensure operation that redis can be good, it is corresponding that switching device can periodically obtain which
The state of redis, optionally, the state of redis includes running status and halted state.If switching device judges the shape of redis
When state is halted state, then switching device can call default script, with corresponding by default script startup switching device
The state of redis.Optionally, the default script can be startredis.sh scripts.Call in switching device
After startredis.sh scripts, the startredis.sh scripts can control redis and start in preset duration, and this is preset
Duration can be 1 minute.
Below, by instantiation, the technical scheme shown in said method embodiment is described in detail.
Exemplary, it is assumed that redis systems include 3 redis, are designated as redis1-redis3 respectively, 3 redis
Correspondence switching device is designated as switching device 1- switching device 3 respectively.Assume again that the main redis of acquiescence that user is arranged is redis1,
It is and the initialization priority of redis1 that user is arranged is respectively 90 for the initialization priority of 100, redis2 and redis3, excellent
First level increment is 50.
When initial, monitoring module according to the setting of user by redis1 arrange based on redis, by redis2 and redis3
It is set to from redis.
Switching device 1 determines that the main redis of redis systems is redis1, then switching dress by interacting with monitoring module
It is 100+50=150 that 1 is put by the priority update of redis1.
Switching device 2 is determined that the main redis of redis systems is not redis2, is then switched by being interacted with monitoring module
The priority update of redis2 is 90 by device 2.
Switching device 3 is determined that the main redis of redis systems is not redis3, is then switched by being interacted with monitoring module
The priority update of redis3 is 90 by device 3.
Switching device 1- switching device 3 determines the highest priority of redis1 by interaction, switching device 1, then switching dress
Put 1 and virtual IP address is set for redis1, and the virtual IP address of redis1 is set to the virtual IP address of redis systems.Assume redis systems
Virtual IP address be IP0, then switching device 1 virtual IP address of redis1 is set to into IP0.
Virtual IP address (IP0) as redis systems are provided with business network element, then business network element can be right according to IP0
Redis1 conducts interviews.
In the running of redis systems, it is assumed that due to breaking down and operation suspension, then monitoring module will for redis1
Redis based on redis2 switchings, now, redis3 is still from redis.
Switching device 1 judges the state of redis1 for halted state, then switching device calls startredis.sh scripts,
And pass through startredis.sh script startup redis1.After redis1 is activated, switching device 1 judges redis systems
Main redis is not redis1, then switching device by the priority update of redis1 for redis1 initial priority 100.
By interacting with monitoring module, switching device 2 determines that the main redis of redis systems is redis2, then switching dress
It is 90+50=140 that 2 are put by the priority update of redis2.
Switching device 3 is determined that the main redis of redis systems is not redis3, is then switched by being interacted with monitoring module
The priority update of redis3 is 90 by device 3.
Switching device 1- switching device 3 determines the highest priority of redis2 by interaction, switching device 2, then switching dress
Put 2 and virtual IP address is set for redis1, and the virtual IP address of redis2 is arranged into IP0.Meanwhile, switching device 1 judges that redis1 also sets
Virtual IP address (IP0) is equipped with, then switching device 1 can delete the virtual IP address of redis1.Certainly, after redis1 is suspended
Setting in redis1 may recover initial setting up, so that the virtual IP address in redis1 is deleted.
Virtual IP address (IP0) as redis systems are provided with business network element, then business network element can be right according to IP0
Redis2 conducts interviews.
In above process, when in redis systems, main redis changes, without the need for sending logical to each business network element
Know message, the IP address of the main redis of the redis systems stored to which without each business network element is updated, only need each
Individual switching device is safeguarded that to the IP address of its corresponding redis simplify carries out the mistake of master-slave swap to redis
Journey, and then improve the efficiency that master-slave swap is carried out to redis.
