  2. 从远端下载
    docker pull mysql
    [root@iZbp17pvndv49r9ozf5hbcZ ~]# docker pull mysql

Status: Downloaded newer image for mysql:latest
docker.io/library/mysql:latest
  3. 查看镜像
    docker images
    [root@iZbp17pvndv49r9ozf5hbcZ ~]# docker images
REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
mysql                latest              c8ee894bd2bd        2 weeks ago         456MB
  4. 然后先创建一个临时的mysql，进入容器中
    docker run --rm --name mysqlTemp -it -v /usr/local/mysql/:/var/lib/mysql  -e MYSQL_ROOT_PASSWORD=123456 mysql /bin/bash

– rm 退出后就删除该容器
-v /usr/local/mysql/:/var/lib/mysql 装主机目录/usr/local/mysql/映射Docker中的/var/lib/mysql目录
-it 交互模式
/bin/bash 进入 bash 命令模式
5. 查看 my.cnf文件。
cat /etc/mysql/my.cnf

#
# The MySQL  Server configuration file.
#

# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Custom config should go here
!includedir /etc/mysql/conf.d/

如果是完整的my.cnf文件，直接复制出去，如果不是，则需要把includedir目录一起复到主机
6. 拷贝配置文件

  • 把Docker中的/etc/mysql/my.cnf文件拷贝到Docker的/var/lib/mysql目录，及主机的/usr/local/mysql/目录中
    cp /etc/mysql/my.cnf /var/lib/mysql
  • 把Docker中includedir目录复制出去
    cp -R /etc/mysql/conf.d/ /var/lib/mysql/conf.d
  1. 退出bash，Docker中临时用的mysqlTemp会被删除
    然后可以查看/usr/local/mysql/目录下有mysql所有的配置文件
    [root@iZbp17pvndv49r9ozf5hbcZ ~]# ls /usr/local/mysql/
conf.d  my.cnf
  2. 这里就可以修改配置了。
    改完之后，创建正式的mysql容器
    docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123455 -v /usr/local/mysql/data:/var/lib/mysql -v /usr/local/mysql/my.cnf:/etc/mysql/my.cnf -v /usr/local/mysql/conf.d:/etc/mysql/conf.d -d mysql
    如果my.cnf 是完整的配置，这里不需要映射conf.d和mysql.conf.d这二个目录
    docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123455 -v /usr/local/mysql/data:/var/lib/mysql -v /usr/local/mysql/my.cnf:/etc/mysql/my.cnf  -d mysql
  • –name 容器名称
  • -p 端口映射
  • -v 配置文件映射：将 宿主机上修改的自定义配置文件，映射到 容器中
  • -e MYSQL_ROOT_PASSWORD 设置root密码
  • -d 守护进程模式运行
