事前准备

1. 关闭selinux

setenforce 0
vim /etc/sysconfig/selinux 
SELINUX=disabled

# 若不关闭，使用docker启动mysql5.7镜像容器时启动不起来，查看日志会有如下错误显示：
ERROR: mysqld failed while attempting to check config
command was: "mysqld --verbose --help"
mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 13 - Permission denied)
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!

command was: "mysqld --verbose --help"
mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 13 - Permission denied)
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!

1. 安装并启动docker

yum install epel-release
yum -y install docker
systemctl start docker.service

1. 创建目录

mkdir -p /datavol/mysql-200/{mysql,conf}

把该文件放到主库所在配置文件路径下：/datavol/mysql-200/conf

配置my.cnf

[client]
port = 3306
default-character-set = utf8mb4

[mysql]
port = 3306
default-character-set = utf8mb4

[mysqld]

安装启动主库

[root@localhost ~]# docker run -d -p 4200:3306 --name=mysql-200 -v /datavol/mysql-200/conf:/etc/mysql/conf.d -v /datavol/mysql-200:/datavol/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7
