Redis容器化部署教程
一、准备工作
(1)安装Docker环境
文章推荐:Docker安装部署教程
(2)获取Redis镜像
[root@10-27-0-224 ~]# docker pull redis:5.0.0 [root@10-27-0-224 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE redis 5.0.0 1babb1dde7e1 2 years ago 94.9MB
(3)创建Redis数据持久化卷
[root@10-27-0-224 ~]# docker volume create redis [root@10-27-0-224 ~]# docker volume ls DRIVER VOLUME NAME local redis [root@10-27-0-224 ~]# docker volume inspect redis [ { "CreatedAt": "2021-10-08T21:31:27-05:00", "Driver": "local", "Labels": {}, "Mountpoint": "/var/lib/docker/volumes/redis/_data", "Name": "redis", "Options": {}, "Scope": "local" } ]

二、运行Redis容器
(1)启动容器
[root@10-27-0-224 ~]# docker run --name my-redis -p 6379:6379 --restart=always --mount source=redis,destination=/var/lib/redis -v /etc/localtime:/etc/localtime -d redis:5.0.0 redis-server --appendonly yes [root@10-27-0-224 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a4685fcbaefb redis:5.0.0 "docker-entrypoint.s…" 9 seconds ago Up 8 seconds 0.0.0.0:6379->6379/tcp redis
(2)参数解读
--name my-redis # 启动后容器名为 my-redis
-p 6379:6379 # 将容器的 6379 端口映射到主机的 6379 端口
--mount source=redis,destination=/var/lib/redis # 将主机 redis卷 挂载到容器的/var/lib/redis
redis-server --appendonly yes # 在容器执行redis-server启动命令,并打开redis持久化配置
(3)连接redis实例
[root@ansible ~]# redis-cli -h 107.155.48.73 -p 6379 # 默认没有密码,可以直接连接 107.155.48.73:6379> config set requirepass ucloud.cn # 给Redis设置密码 OK 107.155.48.73:6379> info # 未验证 NOAUTH Authentication required.
