MYSQL自动安装脚本

cat mysql_auto_install.sh

#!/bin/bash
#Part1:整个流程分3步
#1.mysql官网下载二进制版本的mysql5.7.21安装包(mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz)和mysql_auto_install.sh脚本放至/root目录
#2.执行下文所述的mysql_auto_install.sh脚本
#3.输入您设置的密码登录数据库
###### 二进制自动安装数据库脚本root默认密码:MANAGER, 将脚本和安装包放在/root目录即可.###############
######数据库目录/usr/local/mysql############
######数据目录/data/mysql############
######慢日志目录/data/slowlog############
######端口号默认3306其余参数按需自行修改############
