docker pull mysql

docker run     -p 3306:3306     -e MYSQL_ROOT_PASSWORD=123456     -v /home/data/mysql/data:/var/lib/mysql:rw     -v /home/data/mysql/log:/var/log/mysql:rw     -v /home/data/mysql/config/my.cnf:/etc/mysql/my.cnf:rw     -v /etc/localtime:/etc/localtime:ro     --name mysql8     --restart=always     -d mysql

mysql/data 是数据库文件存放的地方。必须要挂载到容器外，否则容器重启一切数据消失。
mysql/log 是数据库主生的log。建议挂载到容器外。
mysql/config/my.cnf 是数据库的配置文件，在下面会放出来。
/etc/localtime:/etc/localtime:ro 是让容器的时钟与宿主机时钟同步，避免时区的问题，ro是read only的意思，就是只读。
