1.安装完MySQL设置root密码报错如下
[root@vm172-31-0-6 data]# mysqladmin -uroot password "linux@123" mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)'
2.停止MySQL服务
[root@vm172-31-0-6 ~]# systemctl stop mysqld.service
3 安全模式启动
[root@vm172-31-0-6 mysql]# mysqld_safe --skip-grant-tables & [1] 20777 [root@vm172-31-0-6 mysql]# 190315 01:43:28 mysqld_safe Logging to '/var/log/mysqld.log'. 190315 01:43:28 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
