参考 https://blog.youkuaiyun.com/qq_35995514/article/details/134350572?spm=1001.2014.3001.5501
源文章是centos 的 教程，这里为了大家的方便，再原作者基础上做了修改，记录了ubuntu的22.04的我的配置，加了一个删除原有mysql 的脚本

一、安装下载

下载地址：

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.44-el7-x86_64.tar.gz

脚本和tar包结构

my.cnf 配置文件

[root@windp-aio opt]# cat config/my.cnf 
[mysql]
socket=/var/lib/mysql/mysql.sock
# set mysql client default chararter
default-character-set=utf8

[mysqld]
socket=/var/lib/mysql/mysql.sock
# set mysql server port  
port = 3306
# set mysql install base dir
basedir=/usr/local/mysql
# set the data store dir
datadir=/usr/local/mysql/data
# set the number of allow max connnection
max_connections=200
# set server charactre default encoding
character-set-server=utf8
# the storage engine
default-storage-engine=INNODB
lower_case_table_names=1
max_allowed_packet=16M
explicit_defaults_for_timestamp=true
[mysql.server]
user=mysql
basedir=/usr/local/mysql

二、执行安装

install_mysql.sh 安装脚本

#! /bin/bash
#
