安裝mysql8.0

添加mysql源

rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
yum --enablerepo=mysql80-community install mysql-community-server。
systemctl start mysqld
systemctl status mysqld
grep "A temporary password" /var/log/mysqld.log  //mysql臨時生成的密碼
mysql -u root -p
	輸入密碼即可登陸
mysql> set global validate_password.policy=0;
mysql> set global validate_password.length=1;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';    //設置登錄密碼
mysql> create user 'php'@'192.168.88.130' identified by 'vfds5325@$346%$#Q';     //創建php用戶,密碼複雜一點，否則鏈接失敗
mysql> GRANT ALL ON *.* TO 'php'@'192.168.88.130';     //允許php登陸
mysql> flush privileges;
