本文介绍在linux下使用docker安装mysql和redis。
原文地址：代码汇个人博客 http://www.codehui.net/info/59.html
测试环境：centos7.6,docker 18.09.1
首先要确保docker环境已经安装成功
[root@localhost ~]# docker --version
Docker version 18.09.2, build 6247962
Docker 安装 Mysql
- 安装镜像
直接跳过docker search mysql这一步，我们直接安装官方mysql5.5的镜像
[root@localhost ~]# docker pull mysql:5.5
安装完成查看本地镜像,标签名为5.5
[root@localhost ~]# docker images mysql
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql 5.5 50ba61f07d0c 7 days ago 205MB
- 运行容器
[root@localhost ~]# docker run -p 3306:3306 -d --name mymysql -v /docker/mysql/data:/usr/share/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.5
979542f0c201ed229a548a260cd3bf0d8fbafb99ecb3e75e74cdc302358575f6
-p 3306:3306：将容器的 3306 端口映射到主机的 3306 端口。
-v /docker/mysql/data:/usr/share/mysql：将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。
-e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。
- 查看容器运行情况
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
979542f0c201 mysql:5.5 "docker-entrypoint.sh" 2 minutes ago Up 2 minutes 0.0.0.0:3306->3306/tcp mymysql
- 使用mysql
[root@localhost ~]# docker exec -it mymysql bash
root@979542f0c201:/# mysql -u root -p
Enter password:

Docker 安装 Redis
- 安装镜像
这里安装redis3.2的官方镜像版本
[root@localhost ~]# docker pull redis:3.2
安装完成查看本地镜像,标签名为3.2
[root@localhost ~]# docker images redis
REPOSITORY TAG IMAGE ID CREATED SIZE
redis 3.2 87856cc39862 4 months ago 76MB
- 运行容器
[root@localhost ~]# docker run -p 6379:6379 -d --name myredis -v /docker/redis/data:/data redis:3.2 redis-server --appendonly yes
84631392a9fab37c08976673c75a701687bfe6a3443209db92a19bab8e107b6b
-p 6379:6379 将容器的6379端口映射到主机的6379端口
-v /docker/redis/data:/data: 将主机中当前目录下的data挂载到容器的/data
redis-server --appendonly yes: 在容器执行redis-server启动命令，并打开redis持久化配置
- 查看容器运行情况
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
84631392a9fa redis:3.2 "docker-entrypoint.s猞" 16 seconds ago Up 13 seconds 0.0.0.0:6379->6379/tcp myredis
979542f0c201 mysql:5.5 "docker-entrypoint.s猞" 14 minutes ago Up 14 minutes 0.0.0.0:3306->3306/tcp mymysql
- 使用redis
[root@localhost ~]# docker exec -it myredis redis-cli
127.0.0.1:6379> ping
