Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The embodiment of the invention discloses a kind of multiserver switching method, shown in Figure 1, this method includes：
Step S11：When detecting former master server inactivation from server group, then from each from server phase in server group
Mutually send timestamp.
Specifically, in normal operation, from server group can receive that former master server sends in fortune signal, work as original
Master server is inactivated, and fails in first threshold to receive that former master server sends in fortune signal from server group, just can be obtained
Know former master server inactivation, former master server sends in fortune signal for example, failing to receive in 10 seconds from server group, just
Former master server inactivation is learnt, or receives the information of former master server inactivation, former master server inactivation is learnt.
Wherein, when detecting former master server inactivation from server group, then from each from server in server group
Timestamp can be sent to each from server, the time described in timestamp can learn that master server loses to be each from server
Time living, or each time that timestamp is sent from server, delay setting can also be carried out, do not limited herein.
It is understood that there is different degrees of delay due to being communicated between each server, so respectively being obtained from server
Difference can be had by knowing the time of former master server inactivation, meanwhile, each from server after former master server inactivation is learnt, response
Time influences the transmission time as different from the current running status of server, it is possible to during using receiving
Between and send the time as the time in timestamp, in actual applications, in order to avoid standby master server determination excessively with
Machine, therefore can be set carrying out different delays to the time in timestamp from server, made with playing certain sequence
With.
For example, have 3 from server, respectively first from server, second from server and the 3rd from server,
One learns that the time of former master server is 8 from server:30, it is 8 to send the timestamp time:33, second learns original from server
The time of master server is 8:31, it is 8 to send the timestamp time:32, the 3rd learns that the time of former master server is from server
8:33, it is 8 to send the timestamp time:35；When being punctual using the time of learning, first from server, second from server and the 3rd
It is respectively 8 from the time in the timestamp of server:30、8:31 and 8:33；When being punctual to send the time, first from service
Device, second are respectively 8 from the time in the timestamp of server from server and the 3rd:33、8:32 and 8:35；When there is delay to be
Regularly, user carries out delay setting to second from server in advance, and 2 points are delayed from the time in the timestamp of server to second
Clock, second is punctual from server using the time of learning, the time of timestamp is 8:33, using send the time be it is punctual, timestamp
Time is 8:34.
Step S12：Each timestamp received from server by utilizing judge described in the timestamp that itself sends when
Between judge itself whether relative importance value highest, if it is, being used as standby master server.
Specifically, each will receive other timestamps sent from server from server, and utilize each time
Time in the timestamp that is sent with itself of time recorded in stamp is contrasted, for example, in judging the timestamp of itself transmission
Whether the time of record is earliest, if it is, can be as standby master server, and switch over, perform standby main clothes
The function of business device.For example, have 3 from server, respectively first from server, second from server and the 3rd from service
Device, first is respectively 8 from the time in the timestamp of server from server and the 3rd from server, second:30、8:31 and 8:
33, then first from the time earliest relative importance value highest of server, therefore first is used as standby master server from server.
It can be seen that, in the embodiment of the present invention in the case where former master server is inactivated, timestamp is mutually respectively sent from server,
Each timestamp received from server by utilizing judges that the time described in the timestamp itself sent judges whether itself is excellent
Highest is first spent, if it is, as standby master server, so that ensure that after former master server inactivation can be smoothly by from clothes
Business device is continued to run with instead of its function, provides the user reliable data, services.
It should be noted that the temporal meaning of each timestamp sent from server can be different, for example, first from clothes
The time being engaged in the timestamp of device can be the first learning the time from server, and second from the time in the timestamp of server
It can be the second time that timestamp is sent from server, have no effect on and filtered out from from server group as standby main service
Device from server.
In actual applications, time in multiple timestamps from server occurring unavoidably the same situation, therefore, working as
Multiple timestamps from server transmission are the same, then can be selected using static allocation set in advance order as standby
Master server from server.
Specifically, when multiple timestamps from server transmission are the same, from respective from server judgement in server group
Static allocation order, relative importance value highest is changed into standby master server from server；Static allocation order can be pre- by user
First set, specify and the order of former master server is each switched to from server, for example, there are 10 from server group from clothes
Business device, it is 1 to 10 to the tenth from the numbering of server from server to specify first, sets and is cut according to the order of numbering from small to large
Change, e.g., when former master server inactivation, then numbering is 1 first to be changed into standby master server from server priority degree highest；From clothes
In business device group from server after former master server inactivation is learnt, the static allocation order of itself is just inquired about, when from server
Confirm then to switch to standby master server from server as relative importance value highest certainly.
Further, when former master server recovers normal, to make former master server resume work, it is necessary to make standby main clothes
Business, which is thought highly of, newly to be switched to from server, continues original work by former master server, therefore, when standby master server detects original
Master server recovers normal, then the data during former master server is inactivated are sent to former master server, and standby master server
It is changed into from one in server group from server.
Specifically, the data during standby master server is run all are sent to former master server, i.e. by the main clothes of original
Data before business device recovers normally are all sent to former master server, so that former master server can continue to processing data, no
The loss and interruption of data occurs, it is ensured that the stability of operation, after data are transferred, standby master server recovers before it
Operation identity, be changed into, from server, working on.
It should be noted that have from server send timestamp delay may it is larger, or inactivated can not in time by
Timestamp is sent to other from server, so as to cause the time for being delayed switching server, therefore, each presetting from server
Time inscribed receipts timestamp, sends timestamp, not to rear continued access more than that will not continue after waiting after preset time from server
The timestamp received is judged, for example, each since server timing, preset time confirming after former master server inactivation
For 5 minutes, the time described in the timestamp and own timestamp that receive in 5 minutes is contrasted from server, and
Timestamp more than 5 minutes will be contrasted no longer, and do not wait more than the time sends timestamp from server, can be effective
Improve switching efficiency.
The embodiment of the present invention further correspondingly discloses a kind of multiserver switching system, and shown in Figure 2, the system includes：
Sending module 11, for when detect former master server inactivation from server group, then from server group it is each from
Server mutually sends timestamp；
Judge module 12, the timestamp for each being received from server by utilizing judge itself whether relative importance value highest,
If it is, being used as standby master server.
It can be seen that, in the embodiment of the present invention in the case where former master server is inactivated, timestamp is mutually respectively sent from server,
Each timestamp received from server by utilizing judges that the time described in the timestamp itself sent judges whether itself is excellent
Highest is first spent, if it is, as standby master server, so that ensure that after former master server inactivation can be smoothly by from clothes
Business device is continued to run with instead of its function, provides the user reliable data, services.
Specifically, above-mentioned sending module 11, can include detection unit；Wherein,
