阿里云服务器安装mysql

1wget http://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm

2yum localinstall mysql80-community-release-el7-1.noarch.rpm

3yum install mysql-community-server

4sudo grep 'temporary password' /var/log/mysqld.log

5sudo grep 'temporary password' /var/log/mysqld.log

6sudo service mysqld start

##查看默认密码
shell> sudo grep 'temporary password' /var/log/mysqld.log
##使用默认密码登陆
shell> mysql -uroot -p
#MySQL8.0修改密码需要有大小写字母、数字、特殊字符组合
mysql> alter user 'test'@'%' identified with mysql_native_password by 'MyNewPass4!';

然后阿里云开发端口ok
