（1）# bind 127.0.0.1 -::1 注释掉，不注释只能本机访问 （2）port 7001 根据文件后缀端口修改，如果docker网络采用桥接方式，此处也可以都使用默认的6379端口，每个docker容器的网络都是独立的 （3）daemonize no ，此处必须设置成no，不然docker容器一启动就停掉。设置成yes，redis进程就以守护进程运行，docker容器检测到没有前台进程，所以容器直接停掉 （4）pidfile "/var/run/redis_7001.pid" 根据端口号修改 （5）logfile "/data/redis7001.log" 此处将log文件存放的路径设置到容器的/data路口，刚开始设置了一个其他路径，容器启动的时候提示权限不够 （6）dbfilename "dump7001.rdb" rdb数据文件的名称，按照端口号修改 （7）dir "/data" 数据文件存放的路径 （8）requirepass "123456" redis的密码，根据实际情况进行设置 （9）appendonly yes 是否开启aof持久化配置，根据实际情况配置 （10）appendfilename "appendonly7001.aof" aof文件的名称 （11）appendfsync everysec aof持久化策略 ，always 、no （12）cluster-enabled yes 开启集群模式，设置成yes （13）cluster-config-file /data/nodes-7001.conf 集群配置文件存放位置 （14）cluster-node-timeout 15000 节点通信超时时间

冒号前面表示宿主机的路径，冒号后面表示容器的路径，/data是容器默认的工作路径。 --network=host docker的网络模式，此处选用host模式 --name redis-7001 docker容器的名字 redis:6.2 docker镜像的名字 redis-server /usr/local/etc/redis/redis7003.conf 以指定的配置文件启动redis
