问题描述

问 题

安装mysql

# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server

启动mysql
service mysqld restart
设置密码

[root@YFPUNzLr ~]# mysql -uroot
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

可我没设置密码啊，网上找了几个方式都没用。

解决方案

网上找到的有效答案：
密码在/var/log/mysqld.log这个文件里
可以用grep 'temporary password' /var/log/mysqld.log来查询，也可以自己在文件里找。

[root@YFPUNzLr ~]# grep 'temporary password' /var/log/mysqld.log

[root@YFPUNzLr ~]# mysql -uroot -p
