3.运行MySQL容器

#开通端口
firewall-cmd --zone=public --add-port=3308/tcp --permanent
firewall-cmd --reload

#创建容器
docker run -d -p 3308:3306 --privileged=true  -v /docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root123 --name mysql mysql:5.7.30 --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci

4.参数说明:

run　      run 是运行一个容器
-d　       表示后台运行
-p　　     表示服务器端口和容器内部端口映射关联
--privileged=true　                      设值MySQL 的root用户权限, 否则外部不能使用root用户登陆
-v /docker/mysql/conf/my.cnf:/etc/my.cnf 将服务器中的my.cnf配置映射到docker中的/docker/mysql/conf/my.cnf配置
-v /docker/mysql/data:/var/lib/mysql　　 同上,映射数据库的数据目录, 避免以后docker删除重新运行MySQL容器时数据丢失
-e MYSQL_ROOT_PASSWORD=123456　　　      设置MySQL数据库root用户的密码
--name mysql　　　　                     设值容器名称为mysql
mysql:5.7.30　　                         表示从docker镜像mysql:5.7中启动一个容器
--character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci  设值数据库默认编码

5.新建容器内MySQL的用户并登录

#先进入容器
docker exec -it mysql bash

#执行MySQL命令, 输入root密码, 连接MySQL
mysql -uroot -proot123

#查看版本和端口
