在linux系统中安装mysql服务器详细步骤并解决ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using passw
1. 提示 /tmp/mysql.sock 丢失
service mysql start
提示 /tmp/mysql.sock 丢失，则重启服务器，会自动建立 /tmp/mysql.sock 文件
2. 提示 ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
# mysql -uroot -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
使用网上介绍的方法修改root用户的密码：
# mysqladmin -uroot -p password 'newpassword'
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: YES)'
现在终于被我找到了解决方法，如下（请先测试方法三，谢谢！）：
方法一：
# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
# /etc/init.d/mysql restart
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
mysql>
