2、上传安装包和安装脚本

mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz  安装包

mysql_install5.7.sh  安装脚本

注:俩个文件同时放在一个目录下

[root@localhost]# vim mysql_install5.7.sh  #添加安装脚本

#!/bin/bash
# -*- codeing = utf-8 -*-
# @Time : 2021/11/7 22:11
# @Author : xiaoguaishou
# @File : mysql_install5.7.sh
# @Software : PyCharm

#1.设置mysql安装目录
mysql_install=/home
#2.设置mysql端口
mysql_port=20001
#3.设置mysql版本号
mysql_version=mysql-5.7.36-linux-glibc2.12-x86_64

#清理系统环境
rpm -e `rpm -qa |grep mariadb` --nodeps
rm -rf /var/lib/mysql
rm -rf /etc/my.cnf.d/
rm -rf /etc/my.cnf
rm -rf /etc/init.d/mysql

#前面初始化mysql为空密码
#1、新建远程访问用户:
mysql -e "grant all on *.* to deploy@'%' identified by 'VqxSINILWT7i!9Db';"
#2、权限查看:
#mysql> FLUSH PRIVILEGES;
mysql -e "flush privileges;"
#设置root登陆密码
mysql -e "SET PASSWORD = PASSWORD('tzIrmrMrRsCqFg&V');"
#3、输出密码:
echo '
root密码:tzIrmrMrRsCqFg&V
deploy密码:VqxSINILWT7i!9Db
'
firewall-cmd --zone=public --add-port=$mysql_port/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-port

3、使用方式

[root@localhost]# chmod +x mysql_install5.7.sh  #授权

[root@localhost]# ./mysql_install5.7.sh  #执行安装

等待安装完成..........哈哈,安装mysql就是这么简答
