mysql脚本安装

#!/bin/bash
tar -zxf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
#将二进制包移动到/usr/local/mysql
mv mysql-5.7.22-linux-glibc2.12-x86_64 /usr/local/mysql
#创建data目录
mkdir /usr/local/mysql/data
#创建用户和组并赋予文件夹权限
groupadd -r mysql
useradd -r -g mysql -M -s /bin/false mysql
chown -R mysql:mysql /usr/local/mysql
#删除centos7中自带的mariadb-libs
rpm -e mariadb-libs --nodeps
#设置my.cnf配置文件

随便vim一个以sh为后缀得文件
比如 mysql.sh
写入上面得内容
上传mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz提取码：f0um
最后执行一下mysql.sh脚本
