使用docker安装mysql和redis

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

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
