Lose, described caching server will empty the IP address of the master server of its storage previous, master server loses lease lock to be had
Authority that is to say, that master server lease lock lose effect, not in the data, services function having, caching server enter
The step of described the reception server registration request, redefines the process of master server.
Lease is locked and is sent after master server by described caching server, and caching server will receive from described master server
Renewed treaty request, judge whether described master server meets renewed treaty condition, this judgement can also be realized by following embodiments,
Including：
By relatively more described renew a contract the request reception time whether with the renewed treaty time set in advance when setting up lease mechanism
Match, if so, then renew a contract successfully, if it is not, then renewing a contract unsuccessfully.Implementation procedure after this step judged result and above-mentioned judgement knot
The implementation procedure of fruit is identical, is not repeating again.
It is understood that the described renewed treaty time set in advance can be, obtain described lease data after set when
Between be worth.For example：Set the renewed treaty time as the N second, this N second is less than lease and locks the time limit, will receive every N second caching server
The renewed treaty request sending from the master server holding lease lock.
For the described master server after avoiding acquisition to authorize because failure and other reasons cause server providing services function limitation,
The application in described step 102, that is,：The registration request of the reception server, chooses the server meeting registration condition as main clothes
Business device, and, to described master server, the described master server of mandate provides data, services to send lease data in described lease mechanism
Also include：
Re-register request time according to set in advance in described lease mechanism, receive from except described master server
Server in addition re-register request.
Re-registering described in judgement and ask whether to meet to re-register success conditions, if meeting, judging described lease machine
System, with the presence or absence of the described master server authorizing, if so, then returns and re-registers failure, if it is not, then execute described selection meeting
Re-register the step as master server for the server of success conditions；If being unsatisfactory for, returning and re-registering failure.
Ask whether to meet to re-register in request condition step re-registering described in above-mentioned judgement, specific implementation
Can be, by re-registering described in comparison whether the reception time of request presets renewed treaty time and described rent between described
About between the lock time limit, for example：Preset the renewed treaty time for 5 seconds, the lease lock time limit is 10 seconds, if caching server receives
The request time that re-registers be between the 6-9 second, then meet and re-register request condition, caching server judges described rent afterwards
Whether there is, about in mechanism, the master server authorizing, if it is present return re-registering failure, caching server waits next
What secondary server sent re-registers request；If it does not, choose meeting the server re-registering request condition as master
Server；If what caching server received re-registers the scope that request time exceeds the 6-9 second, return and re-register mistake
Lose, enter next round and re-register request.
