准备工作
创建用户
useradd mysql
删除老版本
rpm -qa |grep mysql
rep -e mysql包
重命名默认的mysql配置文件
mv /etc/my.cnf /etc/my.cnf.old
下载mysql
wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.35.tar.gz
安装依赖
yum -y install make gcc-c++ cmake bison-devel ncurses-devel
安装配置
解压
tar -xf mysql-5.6.35.tar.gz
cd mysql-5.6.35
编译安装

配置启动
cd /home/heron/mysql-3306/
mkdir logs etc tmp var
初始化
vim /home/heron/mysql-3306/etc/my.cnf
