Centos7.5 生产环境搭建MySQL 5.7主从

一. 先有外网的机器，下载MySQL 5.7官网软件包
官网下载链接：
为了方便，我这里将安装MySQL5.7需要的官方软件包下载链接地址就直接贴上来
使用官方RPM包安装，需要安装5个包，分别是下面的5个链接，都是官方链接

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-common-5.7.23-1.el7.x86_64.rpm
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-libs-5.7.23-1.el7.x86_64.rpm
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-client-5.7.23-1.el7.x86_64.rpm
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-server-5.7.23-1.el7.x86_64.rpm
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-devel-5.7.23-1.el7.x86_64.rpm

二. 安装
使用FTP软件，将软件包上传至内网2台数据库服务器77/78的/tmp目录下
安装rpm前，先要将MariaDB数据库和libs卸载掉

    # yum remove mariadb mariadb-server mariadb-devel mariadb-libs

安装MySQL

   #  rpm -ivh mysql-community-libs-5.7.23-1.el7.x86_64.rpm 
   #  rpm -ivh mysql-community-common-5.7.23-1.el7.x86_64.rpm 
   #  rpm -ivh mysql-community-libs-5.7.23-1.el7.x86_64.rpm 
   #  rpm -ivh mysql-community-client-5.7.23-1.el7.x86_64.rpm 
   #  rpm -ivh mysql-community-server-5.7.23-1.el7.x86_64.rpm 
   #  rpm -ivh mysql-community-devel-5.7.23-1.el7.x86_64.rpm

三. 定制配置数据库
四. 配置主从
五. 验证
