Docker 安装 MySQL

方法一、docker pull mysql

查找Docker Hub上的mysql镜像

runoob@runoob:/mysql$ docker search mysqlNAME                     DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDmysql                    MySQL is a widely used, open-source relati...   2529      [OK]       mysql/mysql-server       Optimized MySQL Server Docker images.

 这里我们拉取官方的镜像,标签为5.6

runoob@runoob:~/mysql$ docker pull mysql:5.6 # 用网易镜像加速 docker pull hub.c.163.com/library/mysql:5.7

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为mysql,标签为5.6的镜像。

runoob@runoob:~/mysql$ docker images |grep mysqlmysql               5.6                 2c0964ec182a        3 weeks ago         329 MB

方法二、通过 Dockerfile构建

创建Dockerfile

首先，创建目录mysql,用于存放后面的相关东西。

runoob@runoob:~$ mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf

data目录将映射为mysql容器配置的数据文件存放路径

logs目录将映射为mysql容器的日志目录

conf目录里的配置文件将映射为mysql容器的配置文件

进入创建的mysql目录，创建Dockerfile

通过Dockerfile创建一个镜像，替换成你自己的名字

runoob@runoob:~/mysql$ docker build -t mysql .

创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像

runoob@runoob:~/mysql$ docker images |grep mysqlmysql               5.6                 2c0964ec182a        3 weeks ago         329 MB

使用mysql镜像

运行容器

runoob@runoob:~/mysql$ docker run -p 3307:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.621cb89213c93d805c5bacf1028a0da7b5c5852761ba81327e6b99bb3ea89930erunoob@runoob:~/mysql$

命令说明：

• -p 3307:3306：将容器的 3307 端口映射到主机的 3306 端口。

• -v -v $PWD/conf:/etc/mysql/conf.d：将主机当前目录下的 conf/my.cnf 挂载到容器的 /etc/mysql/my.cnf。

• -v $PWD/logs:/logs：将主机当前目录下的 logs 目录挂载到容器的 /logs。

• -v $PWD/data:/var/lib/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。

查看容器启动情况

runoob@runoob:~/mysql$ docker ps CONTAINER ID    IMAGE         COMMAND                  ...  PORTS                    NAMES21cb89213c93    mysql:5.6    "docker-entrypoint.sh"    ...  0.0.0.0:3306->3306/tcp   mymysql

测试是否成功

查看所有IP

docker inspect --format='{
    {.Name}} - {
    {range .NetworkSettings.Networks}}{
    {.IPAddress}}{
    {end}}' $(docker ps -aq)

查询单个IP，可以不加{

{.Name}} 参数也可以加

docker inspect --format='{
    {range .NetworkSettings.Networks}}{
    {.IPAddress}}{
    {end}}' mymysql

登录测试

mysql -h 172.18.0.2 -p3307 -uroot -p
