Redis/Distributed File Storage System/database storage session solves session inconsistency in the Server Load balancer cluster, redissession Let's talk about the similarities and differences between sessions and cookies. Session and cookie are not only stored on the server, but also stored on the client. Although the session is stored on the server side, it also needs to match with the client. Imagine tha

Redis sentinel cluster construction and Jedis test graphic tutorial [2], redisjedis In Redis, the establishment of sentinel clusters and the Jedis test graphic tutorial [1] have already written the setup and testing of sentinel clusters in Redis. This chapter mainly describes the sentinel Jedis test in

;Configuration of 11.slaveBasically no difference from master, there are a few points to note1. Configuration port needs to use non 6379 if the previous use of the 6379 specific port can be set by itself2. If master uses a password in slave configuration, it is also set to Masterauth bt88883. Set the master's information in the From-Port 6380slaveof IP 63794. If it is Ubuntu please pay special attention to the issue of permissions, if the permissions are not possible, here can view the log if th

The cancellation of things uses the Reset () function. The code is as follows: >>> Import Redis >>> r = Redis. Redis () >>> r.set (' Xie ') true >>> r.set (' Man, ' true >>> pipe = R.pipeline () >>> pipe.multi () >>> pipe.set (' Xie ',) >>> pipe.set (' Man ', >>> pipe.reset () >>> # Reset, transactions are canceled, Pipe.set (' Xie ', 18) and Pipe.set (' Man
