Redis master-slave configuration and master-slave switching

Environment Description:

Main redis:192.168.10.1 6379
From redis:192.168.10.2 6380

First, master-slave configuration

1. Change Aemonize No in the master-slave redis configuration file redis.conf to Yes

2. Modify port 6379 from Redis config file redis.conf to 6380, add slaveof 192.168.10.1 6379

3. Start-up and subordinate service

Master Redis:

[[email protected] redis-2.8.3] # src/redis-server/soft/redis-2.8.3-master/redis-2.8.3/redis.conf

From Redis:

[[email protected] redis-2.8.3] # src/redis-server/soft/redis-2.8.3-slave/redis-2.8.3/redis.conf

4. Test Data synchronization

Master Redis:

[[email protected] redis-2.8.3] # src/redis-cli-p 6379127.0.0.1:6379> set name Abcok127.0.0.1:6379> get name"  ABC"127.0.0.1:6379>

From Redis:

[[email protected] redis-2.8.3] # src/redis-cli-p 6380127.0.0.1:6380> get name"ABC" 127.0.0.1:6380>

5, the default is read and write separation

In from Redis:

[[email protected] redis-2.8.3] # src/redis-cli-p 6380127.0.0.1:6380> set name 123(Error) READONLY you can ' t write against a read only SLA ve.

Second, master-slave switching

1. Stop Master Redis

[[email protected] redis-2.8.3] # src/redis-cli-n 6379 shutdown [[email protected] redis-2.8.3] # src/redis-cli-p 6379 Could not connect to Redis at 127.0.0.1:6379: Connection refusednot connected>

2. Set the master Redis from Redis

[[email protected] redis-2.8.3] # src/redis-cli-p 6380 slaveof NO One Ok

3. Test whether or not the Redis switch from the master Redis

[[email protected] redis-2.8.3] # src/redis-cli-p 6380127.0.0.1:6380> set name 123OK127.0.0.1:6380> get name"  123"127.0.0.1:6380>

4, the original master Redis back to normal, to re-switch back

1) Save the current master Redis data

[[email protected] redis-2.8.3] # src/redis-cli-p 6380127.0.0.1:6380> get name"ABC"127.0.0.1:6380 > Set name 123OK127.0.0.1:6380> get name"123"127.0.0.1:6380 > saveok127.0.0.1:6380> get name"123"127.0.0.1:6380 >  

2) Overwrite the Dump.rdb file copy of the current master Redis root directory with the original master Redis root directory

3) Start the original master Redis

[[email protected] redis-2.8.3] # src/redis-server/soft/redis-2.8.3-master/redis-2.8.3/redis.conf

4) switch in the current master Redis

[[email protected] redis-2.8.3] # src/redis-cli-p 6380 slaveof 192.168.10.1 6379 Ok
