阿里云linux系统centos7，快速安装mysql8.0

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

2.sudo rpm -Uvh mysql80-community-release-el7-1.noarch.rpm

3.sudo yum install mysql-community-server

4.systemctl start mysqld.service   #启动 

   systemctl status mysqld.service #查看状态

   systemctl enable mysqld.service #开机启动mysql

5.cat /var/log/mysqld.log   #查看初始密码

注：冒号点号都是密码内容

6.mysql -uroot -pxxxxxx  #登录 xxxxxx为初始密码

7.ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxx'; #修改初始密码

注：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

即密码不符合要求 set global validate_password.policy=0; #更换密码校验策略即可  mysql8.0 _policy 换成.policy
