#redis单机命令行主从配置步骤（一般是采用配置文件修改设置主从） #1.下载redis.conf文件，并复制几份修改对应配置 wget https://raw.githubusercontent.com/antirez/redis/4.0/redis.conf #2.配置项修改 #主机配置项修改 bind 127.0.0.1 -> bind 0.0.0.0 protected-mode no dbfilename dump.rdb logfile "6379.log" #从机配置项修改 bind 127.0.0.1 -> bind 0.0.0.0 dbfilename dump_slave1.rdb logfile "redis_slave1.log" pidfile /var/run/redis_slave1.pid #3.docker以配置文件形式启动redis #启动master docker run -p 6379:6379 --name myredis79 -v /config/redis.conf:/etc/redis/redis.conf -v /local/docker/data:/data -d redis redis-server /etc/redis/redis.conf #启动slave1 docker run -p 6666:6379 --name myredis-slave1 -v /config/redis-slave1.conf:/etc/redis/redis.conf -v /local/docker/data:/data -d redis redis-server /etc/redis/redis.conf #启动slave2 docker run -p 6667:6379 --name myredis-slave2 -v /config/redis-slave2.conf:/etc/redis/redis.conf -v /local/docker/data:/data -d redis redis-server /etc/redis/redis.conf #启动slave3，如果需要通过master的容器名设置主从需要先用--link连通slave/master的网络或者使用自定义网络启动容器 docker run -p 6668:6379 --name myredis-slave3 -v /config/redis-slave3.conf:/etc/redis/redis.conf -v /local/docker/data:/data -d --link myredis79 redis redis-server /etc/redis/redis.conf #进入从机 gkl@ghost:~$ docker exec -it myredis-slave1 /bin/bash #连接redis客户端 root@6943a4e4d5c8:/data# redis-cli #slaveof master 内网ip port 或者通过容器名绑定slaveof myredis79 6379 127.0.0.1:6379> slaveof 172.17.0.3 6379 OK #从机信息查看 127.0.0.1:6379> info replication # Replication role:slave master_host:172.17.0.3 master_port:6379 master_link_status:up master_last_io_seconds_ago:5 master_sync_in_progress:0 slave_read_repl_offset:5530 slave_repl_offset:5530 slave_priority:100 slave_read_only:1 replica_announced:1 connected_slaves:0 master_failover_state:no-failover master_replid:dd549906cf602b2b00fc7ce0a20656a464d05068 master_replid2:0000000000000000000000000000000000000000 master_repl_offset:5530 second_repl_offset:-1 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:5517 repl_backlog_histlen:14 #主机信息 127.0.0.1:6379> info replication # Replication role:master connected_slaves:3 slave0:ip=172.17.0.8,port=6379,state=online,offset=43322,lag=0 slave1:ip=172.17.0.4,port=6379,state=online,offset=43322,lag=0 slave2:ip=172.17.0.5,port=6379,state=online,offset=43322,lag=0 master_failover_state:no-failover master_replid:7ad03562a7a4e69f3e830a343659f21319ef5823 master_replid2:0000000000000000000000000000000000000000 master_repl_offset:43322 second_repl_offset:-1 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:31721 repl_backlog_histlen:11602
