获取镜像

docker可以使用下面的命令获取镜像:

docker pull mysql:5.7

查找镜像

可以使用下面的命令获取当前下载的所有镜像:

docker images

个人获取到的镜像内容如下:

[zxd@localhost seata]$ docker images
REPOSITORY                          TAG       IMAGE ID       CREATED         SIZE

hello-world                         latest    feb5d9fea6a5   15 months ago   13.3kB

本地创建mysql的映射目录

在正式的启动Mysql镜像之前进行映射目录的配置。

mkdir -p /opt/mysql/data /opt/mysql/logs /opt/mysql/conf

/root/mysql/conf中创建 *.cnf 文件(叫什么都行)。这里以个人创建的mysql.conf为例:

touch mysql.conf

创建容器,将数据,日志,配置文件映射到本机,注意这里的root密码为root:

docker run -p 13306:3306 --name mysql -v /opt/mysql/conf:/etc/mysql/conf.d -v /opt/mysql/logs:/logs -v /opt/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7

运行之后,我们执行docker ps查看当前运行的mysql镜像:

[zxd@localhost conf]$ docker ps
CONTAINER ID   IMAGE                   COMMAND                  CREATED              STATUS              PORTS                                                                                                               NAMES
e95a0bc7b4a4   mysql:5.7               "docker-entrypoint.s…"   About a minute ago   Up About a minute   33060/tcp, 0.0.0.0:13306->3306/tcp, :::13306->3306/tcp                                                              mysql

相关运行参数如下:

-d: 后台运行容器
-p 将容器的端口映射到本机的端口
-v 将主机目录挂载到容器的目录
-e 设置参数

运行之后我们执行下面的命令查看:

[zxd@localhost conf]$ mysql -uroot -proot -P 13306

最后查看/opt/mysql/data目录是否有数据文件:

[zxd@localhost conf]$ sudo ls /opt/mysql/data
auto.cnf    client-cert.pem  ibdata1      ibtmp1      performance_schema  server-cert.pem
ca-key.pem  client-key.pem   ib_logfile0  mysql       private_key.pem      server-key.pem
ca.pem        ib_buffer_pool   ib_logfile1  mysql.sock  public_key.pem      sys

运行容器

docker run -p 13306:3306 --name mysql57 --restart=always -v /opt/mysql/conf:/etc/mysql/conf.d -v /opt/mysql/logs:/logs -v /opt/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7
