Master-slave replication configuration experiment of Redis

Environment Introduction:
OS: Oracle linux 5.6
Redis: redis-2.6.8
Master rac1 192.168.2.101
Slave rac2 192.168.2.102

:
Http://redis.googlecode.com/files/redis-2.6.8.tar.gz

Install and configure redis master-slave Replication
1. master node configuration
[Root @ rac1 opt] tar zxvf redis-2.6.8.tar.gz
[Root @ rac1 opt] redis-2.6.8 cd
[Root @ rac1 redis-2.6.8] # make
[Root @ rac1 redis-2.6.8] # cp src/redis-server/usr/local/bin/
[Root @ maid redis-2.6.8] # cp redis. conf/etc/redis_master.conf
[Root @ maid redis-2.6.8] # cat/etc/redis_master.conf
# If port 0 is specified Redis will not listen on a TCP socket.
Port 6379 # This port is default for redis and can be left unchanged

-- Copy software to slave Node
[Root @ rac1 opt] # scp-r redis-2.6.8 rac2:/opt

2. Slave node configuration
[Root @ rac2 redis-2.6.8] # cp src/redis-server/usr/local/bin/
[Root @ rac2 redis-2.6.8] # cp redis. conf/etc/redis_slave.conf
# If port 0 is specified Redis will not listen on a TCP socket.
Port 6389 # modify the port to the custom port of the slave Node
# Slaveof <masterip> <masterport>
Slaveof 192.168.2.101 6379 # this step is the most critical step. Add the IP address or host and port number of the master.

3. Start the redis Service
-- Start the master node
[Root @ rac1 ~] # Redis-server/etc/redis_master.conf> redis_master.log 2> & 1 & # & enables command execution in the background without affecting screen usage.
