. Now that the system has a new master server and an slave server, the client can continue to use this system to process read and write requests. Because one server is offlineThe performance of the re-launch system may not be comparable to that of the original system, but this recovery operation can avoid the overall system downtime.. Although the method described above can bring the system back online, it is too troublesome to manually execute these operations. For this reas

Implementation of Redis multi-host database and redis Database 1. Copy In Redis, You can execute the SLAVEOF command or set the slaveof option to let one server copy another server. We call the copied server as the master server ), the server that copies the master server is called the slave server ). Assume that there are two Redis servers at 127.0.0.1: 6379 and 127.0.0.1: 12345 respectively. If we send

server that can add multiple redis servers to a server pool and forward the client-sent command requests to each server in the pool for processing, each server in the pool contains some data and processes some command requests. twemproxy allows you to specify the hash function, distribution function, and hash label by setting configuration options, in this way, different database keys are distributed to different servers. twemproxy allows you to set configuration options to enable twemproxy to
