启动 docker
docker compose up -d查看主从状态
master
docker exec -it redis-master redis-cli -a 123456 -c info replicationslave
docker exec -it redis-slave redis-cli -a 123456 -p 6390 -c info replication结果
master
# Replication
role:master
connected_slaves:2
slave0:ip=192.168.142.156,port=6390,state=online,offset=84,lag=1
slave1:ip=192.168.142.155,port=6391,state=online,offset=84,lag=1
slave
# Replication
role:slave
master_host:192.168.142.157

插入数据测试
master
root@master:~# docker exec -it redis-master redis-cli -a 123456 -c set HQ 123

OK
slave
root@slave:~# docker exec -it redis-slave redis-cli -a 123456 -p 6390 -c get HQ
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
"123"
总而言之最总要的一步就是 slaveof <主服务IP> <主服务端口>
