    服务器:centos7.4
    mysql:5.7
    1.下载mysql镜像

    [root@localhost ~]# docker pull mysql
    Using default tag: latest
    Trying to pull repository docker.io/library/mysql ...
    latest: Pulling from docker.io/library/mysql
    
    85b1f47fba49: Pull complete
    5671503d4f93: Pull complete
    3b43b3b913cb: Pull complete
    4fbb803665d0: Pull complete
    05808866e6f9: Pull complete
    1d8c65d48cfa: Pull complete
    e189e187b2b5: Pull complete
    02d3e6011ee8: Pull complete
    d43b32d5ce04: Pull complete
    2a809168ab45: Pull complete
    Digest: sha256:1a2f9361228e9b10b4c77a651b460828514845dc7ac51735b919c2c4aec864b7
    

    2.镜像下载完成后,查看是否下载成功

    [root@localhost ~]# docker images
    REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
    docker.io/jenkins   latest              3f08dc4f3f5d        3 weeks ago         808.9 MB
    docker.io/mysql     latest              5709795eeffa        3 weeks ago         408.2 MB
    

    可以看到repository一栏确实有mysql这个镜像

    3.创建并启动一个mysql容器

    [root@localhost ~]# docker run -d --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=Aa123456! mysql
    265c55de36095f1938f1aa27dcc2887fc4d1c929e51a932daf5061085632ef76
    

    说明:
    -d:以后台运行容器
    --name:指定容器得名称
    -p:将容器得端口映射到宿主机得端口
    -e:指定运行参数,现在指定得是root得密码
    mysql:镜像得名称

    4.查看容器运行状态

    [root@localhost ~]# docker ps
    CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                                              NAMES
    265c55de3609        mysql               "docker-entrypoint.sh"   About a minute ago   Up About a minute   0.0.0.0:3306->3306/tcp                             mysql
    3cfe03dd6e31        jenkins             "/bin/tini -- /usr/lo"   2 days ago           Up 2 days           0.0.0.0:50000->50000/tcp, 0.0.0.0:8081->8080/tcp   jenkins
    

    5.验证

    随便找个mysql客户端,输入刚刚创建得mysql信息,然后点击save,之后可以成功进入mysql就算安装成功了 2.png

    6.创建数据持久化得mysql容器,首先先建立一个数据挂载目录,然后进入目录

    [root@localhost home]# mkdir mysql
    [root@localhost home]# cd mysql/
    

    7.创建容器,并且运行

    [root@localhost mysql]# docker run -p 3306:3306 --name mysql -v $PWD/conf:/etc/mysql -v $PWD/logs:/logs -v $PWD/data:/mysql_data -e MYSQL_ROOT_PASSWORD=Aa123456! -d mysql
    158ee4e9bed0220925ed1402a17b504c482f3e5b1ffc62494de0c3b47fb8fa74
    

    8.查看容器状态

    [root@localhost mysql]# docker ps
    CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                                              NAMES
    158ee4e9bed0        mysql               "docker-entrypoint.sh"   About a minute ago   Up About a minute   0.0.0.0:3306->3306/tcp                             mysql
    3cfe03dd6e31        jenkins             "/bin/tini -- /usr/lo"   3 days ago           Up 3 days           0.0.0.0:50000->50000/tcp, 0.0.0.0:8081->8080/tcp   jenkins
    

    9.验证

    虽然看起来并没有什么差别,但是这样做已经将数据持久化,不会随着容器消失而丢失数据
