[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/

4.创建容器 并启动 mysql

docker run -ti -p 3306:3306 --name mysql -v /home/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /home/mysql/logs:/logs -v /home/mysql/data/mysql:/var/lib/mysql -d mysql:8.0.1 /bin/bash mysqld
