Redis database Master-slave replication configuration

Note: Make sure that Redis is installed before you make the following configuration. This tutorial requires two Redis servers: one when the primary database (master), one when from the database (slave).

1, configure the master-slave structure

For Redis master-slave configuration, only the configuration files from the node need to be modified.

• Primary Database 192.168.20.111:6379
• From the database 192.168.20.112:6379

1.1. Log in to Redis from the database, open the configuration file:

Add a bit of content:

Note: Make sure that port 6379 of the primary database is open.
Open 6379 Port command:

#/sbin/iptables-i input-p TCP--dport 6379-j ACCEPT

2. Start Database 2.1 and start the primary database:

#./redis6379 Start

2.2, start from the database:

#./redis6379 Start

2.3. Use REDIS-CLI to connect to the master database and enter a password to log in:

[Email protected] bin]#. /src/redis-cli-p 6379127.0.0.1:6379> Auth 123456OK

2.4. View the main database info property:

127.0.0.1:6379> Info

There is an item in the property # Replication

2.5. Use REDIS-CLI to connect from the database and enter the password:

[Email protected] etc]#. /src/redis-cli-p 6379127.0.0.1:6379> Auth 123456OK

2.6. View the From Database Info property:

127.0.0.1:6379> Info

There is an item in the property # Replication

3, test 3.1, enter a data in the main database

127.0.0.1:6379> Set num 13

3.2, go to query input data from the database

127.0.0.1:6379> Get num

Sync succeeded!
