docker mysql应用安装

 docker run -p 3306:3306 --name mysql -v /app/mysql/log:/var/log/mysql -v /app/mysql/data:/var/lib/mysql -v /app/mysql/conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7

#8.x版本,引入了 secure-file-priv 机制，磁盘挂载将没有权限读写data数据，所以需要将权限透传， 或者chmod -R 777 /app/mysql/data

# --privileged 特权容器，容器内使用真正的root用户 
docker run -p 3306:3306 --name mysql8 -v /app/mysql/conf:/etc/mysql/conf.d -v /app/mysql/log:/var/log/mysql -v /app/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 --privileged -d mysql

docker cp mysql:/etc/mysql/mysql.conf.d/mysqld.cnf /root/mysqld.cnf
