Redis replication faq

Set key on the 1.master side, no key is received on the slave side

Contents of slave log:

Redis Error condition on socket for SYNC: Broken pipe

Solution: add bind 0.0.0.0 to the masterside to restart redis.

2. Password authentication

In the configuration file

Requirepass master (password)

When operating: redis-cli-p 6379

127.0.0.1 purl 6379 > set h helloworld

(error) NOAUTH Authentication required.

127.0.0.1 purl 6379 > auth master

OK

127.0.0.1 purl 6379 > set h helloworld

OK

127.0.0.1 set number 6379 > 888

(error) NOAUTH Authentication required.

In this way, you have to enter the password for each operation:

Can be set at startup: redis-cli-a master (password)-p 6379

Slave side: profile settings masterauth master

Redis-cli-p 6380

127.0.0.1 6380 > get h

"helloworld"

On the slave side, write appears (error) READONLY You can't write against a read only slave.

Role:slave

Master_host:masterip

Master_port:masterport

Master_link_status:up proves that it is connected to the host.
