Shell脚本——源码编译安装MysSQL

编译安装MySQL

1、软件包

MySQL安装包

将安装包拖至/opt目录下，编辑一个脚本文件，将以下内容复制进去，然后source或者.
执行脚本，等脚本执行完成，即可使用mysql -u root -p点击回车即可进入。

 

2、MySQL一键部署脚本(使用source或者.执行脚本！)

#!/bin/bash

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all && yum makecache
yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake

read -p "您的服务器核心数:" N
yum -y install expect

#安装MySQL环境依赖包
yum -y install ncurses ncurses-devel bison cmake

#创建运行用户
