- 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
- 查看 my.cnf文件。
cat /etc/mysql/my.cnf

[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
secure-file-priv= NULL

!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
- 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
- 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
- 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
