centos7忘记mysql的密码

方法一. 找回安装是的初始密码：

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

方法二. 使用操作系统账号和密码，进行修改密码

mysql -uroot -p

输入你的centos的密码

ALTER user 'root'@'localhost' IDENTIFIED BY '新密码';

注：如果显示 ERROR 1819 (HY000): Your password does not satisfy the current policy requirements，说明你的密码不符合安全要求，

FLUSH PRIVILEGES;
quit;

方法三. 强制进行修改密码

systemctl stop mysqld
systemctl set-environment MYSQLD_OPTS="--skip-grant-tables"
systemctl start mysqld
mysql -u root

进入 mysql

ALTER user 'root'@'localhost' IDENTIFIED BY '新密码';

注：如果显示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements，说明你的密码不符合安全要求，

FLUSH PRIVILEGES;
quit;

systemctl stop mysqld
systemctl set-environment MYSQLD_OPTS=""
systemctl start mysqld
