linux [1045] Access denied for user 'root'@'localhost' (using password: YES)

打开网站的时候报错：

[1045] Access denied for user 'root'@'localhost' (using password: YES)

解决方案：

systemctl stop mariadb.service #中止MariaDB

[root@localhost ~]# mysql
mysql>use mysql
mysql>update user set password=password("123456") where user="root";
mysql>flush privileges;

mysql>quit;

而后启动：systemctl start mariadb
