Redis learning and practice 2 --- Redis master/slave Replication

1. Introduce the masterslave data replication method of Redis, which can be one master, one slave, or one master, multiple slaves. Redis is in the non-blocking mode on the master, that is, when the slave executes data synchronization, master is OK

I. Introduction Redis master/slave Data Replication mode can be one master, one slave, or one master and multiple slave, Redis is in non-blocking mode on the master, that is, when slave executes data synchronization, master is OK

, That is, in ,,.
Service, while

Start slave:

./Redis-server redis-slave.conf

3. Configure an instance:

I have two machines, one linux machine A (ip: 172.16.205.186) and the other windows machine B (ip: 192.168.30.86 ). Server A is configured with A master with port 6379 and Server Load balancer with port 6380. Server B is configured with slave2 and Server Load balancer with ports 6380 and 6381 respectively.

The configuration of A's Linux machine is as follows:

[Root @ DEV etc] # lsredis. conf redis-slave1.conf [root @ DEV etc] # cat redis. confdaemonize yespidfile/usr/local/redis/var/redis. pidport 6379 timeout 300 loglevel debuglogfile/usr/local/redis/var/redis. logdatabases 16 save 900 1 save 300 10 save 60 10000 rdbcompression yesdbfilename dump. rdbdir/usr/local/redis/var/appendonly noappendfsync always [root @ DEV etc] # cat redis-slave1.confdaemonize yespidfile redis-slave.pidport 6380 timeout 300 loglevel verboselogfile stdoutdatabases 16 save 900 1 save 300 10 save 60 10000 rdbcompression yesdbfilename dump-slave.rdbdir/usr/local/redis/var/slaveof 127.0.0.1 6379 appendonly noappendfsync everysec

B's Windows server configuration is as follows:

Slave2:

Daemonize yespidfile redis-slave2.pidport 6380 timeout 300 loglevel verboselogfile stdout2databases 16 save 900 1 save 300 10 save 60 10000 rdbcompression yesdbfilename dump-slave2.rdbdir./slaveof 172.16.205.186 6379 appendonly no

Slave3:

Daemonize yespidfile redis-slave3.pidport 6381 timeout 300 loglevel verboselogfile stdout3databases 16 save 900 1 save 300 10 save 60 10000 rdbcompression yesdbfilename dump-slave3.rdbdir./slaveof 172.16.205.186 6379 appendonly no

In this way, a linux master, a server Load balancer instance, and a windows Server Load balancer instance are implemented. Of course, a server Load balancer instance can also be used as the master of another Server Load balancer instance. "To the corresponding slave information.
