Fig. 1 is the FB(flow block) of the service lock method of one embodiment of the present invention；With reference to Fig. 1, methods described includes
Following steps：
S1：Every server of cloud platform goes to connect zookeeper services, and attempts in zookeeper services
One temporary object znode of middle establishment（Such as/dns/service_A/IN/A/managed）, the value of the znode is correspondence clothes
The ip addresses of business device；
In this step, different services has different znode, and the name of service is exactly the domain name for accessing, and identical takes
Business, this znode is identical, and only one of which can be created successfully, equivalent to lock, due to being required to start service, so
Only one server can successfully create the znode of this service, and this process is robbed in a distributed system equivalent to server
The process of lock.
S2：Start on the server for successfully create znode and service service is externally provided, and successfully create described
The value of znode domain name corresponding with the service service sets up mapping（When computer outside cloud platform accesses the domain name,
The value of znode is then directly resolved to, and because the value of znode is the ip addresses of corresponding server, so can directly access into
Work(creates the server of znode, because oneself registration when this domain name is service startup, service extinction time together disappears, so
The correctness of parsing domain name is ensure that, not there is a problem of synchronous dns servers）；
S3：When the service service cuts off（The problems such as server fail, can cause service service to cut off）
Afterwards, znode corresponding with the service service withers away（The function that zookeeper temporary objects are realized, does not have equivalent to lock
Have, without having to worry about unblock problem）, return to step S1 continues realization and robs lock flow process, continue to start service on other servers
service。
