前言：阿里云服务版本号： uname -a

1.安装jdk11

2.安装mysql 8.0

2.1yum安装mysql8.0

2.2 更新yum源

2.3 开 始安装MySQL，中间有几次要确认输y

2.4 安装完成登录mysql

2.5 修改密码

2.6 测试正常的话就可以使用navicat登录了，但是在阿里云上不行，我们要建策略对3306端口开发才行

## 2.安装mysql 8.0 ##

### 2.1yum安装mysql8.0 ###

wget https://dev.mysql.com/get/mysql80-community-release-el6-3.noarch.rpm

sudo yum localinstall mysql80-community-release-el6-3.noarch.rpm

### 2.2 更新yum源 ###

yum clean all

yum makecache

### 2.3 开 始安装MySQL，中间有几次要确认输y ###

sudo yum install mysql-community-server

这时候可能会报错

### 2.5 修改密码 ###

ALTER USER 'root'@'%' IDENTIFIED BY 'Aggsgs@1234' PASSWORD EXPIRE NEVER;
    
    ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'Aggsgs@1234';
    
    flush privileges;

### 2.6 测试正常的话就可以使用navicat登录了，但是在阿里云上不行，我们要建策略对3306端口开发才行 ###

打开阿里云控制台 参考 [https://www.cnblogs.com/XiaoGao128/p/12520937.html][https_www.cnblogs.com_XiaoGao128_p_12520937.html]

配置安全组：

这样就可以远程连上mysql了
