Modify the redis configuration file. Modify the port to 6380 instead of the default 6379. Then modify the slaveof field and set the master to 127.0.0.7 6379.

After startup:

If the client is connected to the slave, the slave is shown as follows:

[1704] 29 Aug 10:05:52-2 clients connected (0 slaves), 689700 bytes in use

[1704] 29 Aug 10:05:57-db 0: 15 keys (0 volatile) in 16 slots ht.

[1704] 29 Aug 10:06:02-2 clients connected (0 slaves), 689700 bytes in use

If you connect to the master, the result is as follows:

[7304] 29 Aug 10:06:53-accepted 127.0.0.1: 65311

[7304] 29 Aug 10:06:57-db 0: 15 keys (0 volatile) in 16 slots ht.

[7304] 29 Aug 10:07:02-db 0: 15 keys (0 volatile) in 16 slots ht.

2 Replication Test

Store a value in the master, as shown below:

redis 127.0.0.1:6379> SET company  aluOKredis 127.0.0.1:6379> GET company alu(error) ERR wrong number of arguments for ‘get‘ commandredis 127.0.0.1:6379> GET company"alu"redis 127.0.0.1:6379>

Connected to the slave query, which has been automatically copied. As follows:

redis 127.0.0.1:6380> GET  company"alu"redis 127.0.0.1:6380> SET  company  asbOKredis 127.0.0.1:6380>

Slave can be read and written by default. Generally, it should be read-only by default. This can be modified in the configuration file!

Read/write splitting is similar to the read/write splitting mechanism provided by MySQL cluster.
