查看root临时生成的密码

grep ‘temporary password’ /var/log/mysqld.log （这个有用！）

grep ‘password’ /var/log/mysqld.log |head -n 1

//临时密码登录不上去

SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘Gu6020586!@#’);

// mysql登录root

mysql -uroot -p

、、更改密码 需要大小写字母数字加特殊符号

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘密码’;

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘Gu6020586!@#’;

//新增一个远程登录账户

GRANT ALL PRIVILEGES ON *.* TO ‘yangxin’@’%’ IDENTIFIED BY ‘Yangxin0917!’ WITH GRANT OPTION;
