Description
Technical field
The present invention relates to Internet technical field, method and be that more particularly to a kind of server service updates
System.
Background technology
In cloud computing era, it is linked in computing cluster with how allowing service fast transparent, how allows shared joining
Confidence is ceased quickly by all machine discoveries in cluster, it is even more important that how to build so a set of high can
With, safely, be easy to dispose and response quickly service cluster, had become as in the urgent need to address asking
Topic.Such issues that ETCD is for solving provides effective scheme.ETCD is applied under distributed environment
Key/value storage service, is the key assignments storage system of a High Availabitity, is mainly used in configuration sharing kimonos
Business finds.Using the characteristic of ETCD, application program can share information, configuration or service in the cluster
It was found that, ETCD can replicate these data in each node of cluster and ensure that these data are correct all the time.
Container cluster management system Kubernetes, PaaS platform Cloud of the increasing income Foundry of Google and
The Fleet of CoreOS has been widely used ETCD.
ETCD has the following advantages：
ˇ is simple：You just easily can be used with curl based on the API of HTTP+JSON；
ˇ safety：Optional SSL authenticated client mechanism；
ˇ is quick：Each example is per second to support 1,000 write operations；
ˇ is credible：The uniformity of distributed system architecture is adequately achieved using Raft algorithm.
In a distributed system, how between management node state is always a difficult problem.ETCD is special
Service discovery and registration for cluster environment and design, it provides the failure of data TTL, data and changes prison
Depending on functions such as, many-valued, catalogue monitoring, distributed lock atomic operations, in that context it may be convenient to track and manage cluster
The state of node.
But, said method cannot effective process background server delay machine, interrupt service the occurrence of.
In distributed system architecture, large number of server due to processing the interaction of the computing data of flood tide,
Occur system crash, the situation of machine of delaying, and the interruption of server service will result in cannot configuration sharing or
Service discovery, affects the operation of whole distributed system.For this reason, it may be necessary to solve sub-service in the middle part of distributed system
Business device interrupts the generation of service scenario, being capable of rapid recovery system after interrupting occurring.
Content of the invention
The present invention provides the method and system that a kind of server service updates, the operation conditions to background server
Monitored, be capable of the running status of effective monitoring server, the rapid interruption service scenario for finding server,
And take the recovery measure to restart rapidly service, it is to avoid the function of distributed type assemblies server systems and service
Interrupt, the stable operation for keeping distributed server system is provided and is effectively ensured.
Technical scheme provides a kind of method that server service updates, and comprises the following steps：
A, background server are to ETCD server registration；
B, ETCD server arranges the ttl value for background server；
C, background server send ttl value to ETCD server update；
D, ETCD server monitors the ttl value sent by background server；
If ttl value is listened to, step C is executed；
If ttl value is not heard within the time of ttl value, execute E step；
E, restart background server, and return step A.
Further, after step A, ETCD server arranges ttl value for the background server of new registration.
Further, ETCD server arranges different ttl values for different background servers.
Further, background server sends ttl value according to certain frequency to ETCD server update.
Further, frequency time was spaced less than the time defined in ttl value.
Further, ETCD server is provided with management of monitor mechanism, judges that background server sends TTL
Whether value is successful.
Further, the management of monitor mechanism is：ETCD server does not hear backstage clothes for continuous 3 times
The ttl value that business device sends, then judge that the background server corresponding to the ttl value interrupts service.
The system that technical scheme additionally provides a kind of server service renewal, including：Background service
Device, ETCD server, wherein,
Background server is used for ETCD server registration, and periodically sends TTL signal；
ETCD server is used for receiving the registration of background server, is that background server arranges ttl value, with
And background server is restarted in order.
Further, ETCD server arranges ttl value for the background server of new registration；
ETCD server is that different background servers arrange different ttl values.
Further, have no progeny in the TTL signal of background server, ETCD server command restarts backstage
Server；
Background server is restarted backward ETCD server and is registered.
Technical solution of the present invention is designed with special working mechanism to monitor and manage the work of group's server
State, in the case that background server goes wrong, can find rapidly to interrupt the server of service, and
Take measures to recover the service of restarting rapidly, it is to avoid the interruption of the function of distributed cluster system and service, right
Provide in the stable operation for keeping distributed cluster system and effectively ensure.
Other features and advantages of the present invention will be illustrated in the following description, also, partly from explanation
Become apparent in book, or understood by implementing the present invention.The purpose of the present invention and other advantages can
Realize and obtain by specifically noted structure in the specification that is write, claims and accompanying drawing

When registering set ttl value is all adopted during service is provided.
Step 103, background server send ttl value to ETCD server update.
Background server sends ttl value according to certain frequency to ETCD server update；
Frequency time was spaced less than the time defined in ttl value.
Step 104, ETCD server monitor the ttl value sent by background server；
ETCD server is provided with management of monitor mechanism, judges that background server sends whether ttl value becomes
Work(；
The management of monitor mechanism is：ETCD server does not hear background server transmission for continuous 3 times
Ttl value, then judge that the background server corresponding to the ttl value interrupts service；
If ttl value is listened to, 103 steps are executed；
If ttl value is not heard within the time of ttl value, execute 105 steps.
Step 105, restart background server, and return 101 steps.
In order to realize the flow process of above-mentioned server service renewal, the present embodiment additionally provides a kind of server service
