In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of implementation flow chart of the control method of server master-slave redundancy in the present invention, the party
Method the following steps are included:
Step S101: mutually redundant node is configured by first node and second node, and configuration information is stored
In first node and second node.
Each node described herein is the node of total frame in server, that is, is arranged in a casing, each
Node shares an I O board.Since each node shares an I O board, in order to avoid the conflict of control, there is usually one masters
Control working node, i.e. master, remaining node be from control working node, i.e. slave, and slave can be one, can also be with
It is multiple.Master control working node and it is each from control working node can provide service with independent operating for user.
Mutually redundant node is configured by first node and second node, that is, first node and second node has been determined
Between binding relationship, when first node be master control working node master when, second node be corresponding master control backup node
Master-backup, when first node is from control working node slave, second node is corresponding from control backup node
slave-backup。
Configuration information describes the binding relationship of first node and second node, by configuration information be stored in first node with
And in second node, also allowing for first node and second node can know, be which of server node and oneself
Body binding, that is, be mutually backups.And using which node as the second node for corresponding to first node, it usually can be by the people that works
Member is preset.
It include a master control working node in server in a kind of specific embodiment of the invention, a master control is standby
Part node, one from control working node and one from control backup node.
It include two altogether in tetra- road server of Er Shuan in view of double four roads server has extensive and mature application
Node: maste and slave, i.e., one is master control working node, and one is from control working node, and two nodes are simultaneously use
Family provides service.It therefore will in tetra- road server of this programme application Shuan, just be respectively double four for the ease of the application of this programme
Maste and slave in the server of road configure corresponding backup node, and therefore, the server one in this kind of embodiment is used
There are 4 nodes, sees Fig. 2, a master control working node master and a master control backup node master-backup each other
Backup, one is mutually backups with one from control backup node slave-backup from control working node slave.
Step S102: during first node works normally, preset target data is stored in first segment in real time
In point and second node.
First node can be maste or any one slave, might as well be said so that first node is master as an example
It is bright.When master is worked normally, preset target data can be stored in master and master- in real time by master
In backup.In view of nodes break down is chance event, therefore, in order to guarantee the safety of data, the application using
The mode backed up in realtime.
Target data usually can be preset critical data, such as in specific embodiment, and target data is default road
Data in diameter.And preset path usually can be set and be adjusted by user or staff.Certainly, have in part
In body embodiment, second node has the configuration on hardware identical with first node, then can set target data to
Total data in the node of work at present, such as target data are the total data in master, then in master-backup
Also these data can be backed up.Such set-up mode, most of data usually in node are more important
Data or user in the higher occasion of the security requirement of data to applying.
Step S103: when judging first node working condition exception, second node is risen into working node.
It is in off working state when second node is master-backup slave-backup.When judging
When first node working condition exception, such as judge that master working condition is abnormal, then master-backup is risen into work
Make node, i.e., master-backup rises to master at this time.After master-backup rises to master, just substitution is former
First master works, and since target data is stored in master-backup by master before this in real time, makes
Master-backup rises to master and substitutes after original master worked, customer service will not be interrupted.
Judging first node, whether working condition is abnormal, can be and mutually sends the heart between first node and second node
Signal is jumped to be judged, further, it is also possible to auxiliary judgment is carried out by other nodes except first node and second node,
Communication abnormality between first node and second node is avoided, can not but determine the feelings of first node or second node failure
Condition.For example, can be led to a preset slave when communication abnormality between master and master-backup
Letter, can be normally normal node with the slave node communicated.
Step S104: after first node restores normal operating conditions, first node is fallen to according to configuration information
Inoperative node, and the target data in second node is backed up in first node.
After first node restores normal operating conditions, it is in working condition since second node has risen, instead of
The work of first node, in order to avoid the conflict of control, first node falls to inoperative node at this time.Such as previous example
In, refering to Fig. 3, after master working condition exception, master-backup rises to master and substitutes original master,
After original master restores normal operating conditions at this time, master-backup is just fallen to, due to first node and the second section
It is stored with configuration information in point, according to configuration information, second node can back up target data in first node, certainly,
Second node described herein can back up target data in first node, refer to that former second node can be standby by target data
In former first node, namely at this time, former second node rises to new first node to part, and new first node is standby by target data
Part is in new second node.Also, the backup of target data described herein refers to that former master falls to master-
After backup, from obtaining the target data for having storage in two nodes before this in current new maste in batches, and
Hereafter in operational process, new target data is constantly obtained from new master.
Using method provided by the embodiment of the present invention, comprising: configure first node and second node to standby each other
The node of part, and configuration information is stored in first node and second node；During first node works normally,
Preset target data is stored in first node and second node in real time；When judging that first node working condition is abnormal
When, second node is risen into working node；After first node restores normal operating conditions, according to configuration information by first
Node falls to inoperative node, and the target data in second node is backed up in first node；Wherein, work as first node
When for master control working node, second node is corresponding master control backup node, when first node is from control working node, second
Node is corresponding from control backup node.
It is stored with configuration information in first node and second node, so that first node and second node can be with
Know which node is mutually backups with itself.During first node works normally, in real time by preset number of targets
According to being stored in first node and second node, also avoid due to the extremely caused loss of data of first node.When sentencing
When disconnected first node working condition exception out, second node is risen into working node, restores to work normally shape in first node
After state, first node is fallen to by inoperative node according to configuration information, and the target data backup in second node is existed
In first node.Due to former second node instead of former first node as working node so that business will not interrupt.Therefore,
The scheme of the application efficiently avoids the extremely caused service disconnection of server node and loss of data.
In a kind of specific embodiment of the invention, in step s 103 judge that first node working condition is abnormal
Later, further includes: record current time.
In this kind of embodiment, it can recorde down the time for judging first node working condition exception, be also advantageous for

In a kind of specific embodiment of the invention, the target data in second node being backed up in step S104
After in first node, further includes:
When the duration for judging that first node works normally is higher than preset duration threshold value, first node is risen to
Working node, and second node is fallen into inoperative node.
In view of the effect of second node is to carry out data backup to first node, and rise to first node substitution original
The work of first node, if according to the related hardware of standard configuration second node identical with first node, it naturally can be real
The scheme of existing the application, but more resource may be needed.In this embodiment, it can use lower hardware resource to set
Second node is set, this is allowed for after first node working condition exception, it will usually power on restarting, restore normal again
Work, therefore, in this kind of embodiment, when the duration for judging first node normal work is higher than preset duration threshold value
When, illustrate that former first node has returned normal condition, former first node is just risen into working node, and itself is declined
For inoperative node.In such embodiment, second node only needs of short duration substitution first node to provide service, remaining when
The only first node backup that carries out target data, hardware resource needed for advantageously reducing second node, i.e. second node
Hardware resource configuration is configured lower than the hardware resource of first node.
