Docker - MySQL-5.7.19 (CentOS 7.3)

參考於：https://hub.docker.com/r/mysql/mysql-server/

1.獲取MySql鏡像

[root@hanzo hanzo]# docker search mysql
NAME     DESCRIPTION    STARS     OFFICIAL   AUTOMATED
mysql    MySQL is a widely used, open-source relati...   4976      [OK] 
......
[root@hanzo hanzo]# docker pull mysql
......
[root@hanzo hanzo]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               latest              b4e78b89bcf3        43 hours ago        412MB
......

2.啓動實例

sudo docker run -d \
    -p 3306:3306 \
    --name mysql \
    -v $PWD/Dockers/mysql/conf:/etc/mysql/conf.d \
    -e MYSQL_ROOT_PASSWORD=guiwang \
    mysql:latest

普通用戶啓動：

[hanzo@hanzo ~]$ sudo docker run -d \
>     -p 3306:3306 \
>     --name mysql \
>     -v $PWD/Dockers/mysql/conf:/etc/mysql/conf.d \
>     -e MYSQL_ROOT_PASSWORD=guiwang \
>     mysql:latest
d1fefcac7ca160635e90eadee054b9069f8ab8d778e5190e8fd4a6c70fd7cd4f
[hanzo@hanzo ~]$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
d1fefcac7ca1        mysql:latest        "docker-entrypoint..."   8 minutes ago       Up 8 minutes        0.0.0.0:3306->3306/tcp   mysql

• -p 3306:3306：将容器的3306端口映射到主机的3306端口
• -v $PWD/Dockers/mysql/conf:/etc/mysql/conf.d：将主机当前目录下的/Dockers/mysql/conf目錄挂载到容器的/etc/mysql/conf.d目錄。根據需求定義目錄，在所定義的目錄下內置一個後綴名爲cnf的文件，然後在執行上述命令。
• -e MYSQL_ROOT_PASSWORD=guiwang：初始化root用户的密码

3.連接MySql

• 通過容器的MySql命令行工具連接

[root@hanzo hanzo]# docker exec -it mysql mysql -uroot -p
Enter password:

[root@hanzo hanzo]# docker exec -it mysql bash
root@d1fefcac7ca1:/# mysql -uroot -p
