MYSQL自动安装脚本的方法

[root@alimysql06 ~]# ./mysql_auto_install.sh

########### A tool to auto-compile & install MySQL on Redhat/CentOS 6 or 7 Linux ################

################检查本机安装mysql的基本条件########################

Checking user :

user is root, this is ok!

checking os version

os is linux,this is ok!

mysql datadir /data/mysql is exist! ,this is fail!

[root@alimysql06 ~]# 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############
