一、下载镜像
docker pull mysql8.0二、创建文件夹
mkdir -p /app/mysql/conf
mkdir -p /app/mysql/logs
mkdir -p /app/mysql/data
三、定义配置文件
在conf文件夹里创建my.cnf文件，并添加如下配置；
/app/mysql/conf/my.cnf
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
[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
lower_case_table_names=1
# Custom config should go here
!includedir /etc/mysql/conf.d/四、启动容器实例
docker run -p 3306:3306 --name mysql8 --restart=always -v /app/mysql/conf/my.cnf:/etc/mysql/my.cnf:rw -v /app/mysql/logs:/var/log/mysql -v /app/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -e TZ=Asia/Shanghai -d mysql:8.0
