linux mysql

mysql安装与配置
http://www.centoscn.com/mysql/2014/1211/4290.html
如果期间报错

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

那么

#1.停止mysql数据库
/etc/init.d/mysqld stop 
#2.执行如下命令(屏蔽权限)
mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
#3.使用root登录mysql数据库(mysql数据库是自带的)
mysql -u root mysql 
#4.更新root密码
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
#5.刷新权限 
mysql> FLUSH PRIVILEGES; 
#6.退出mysql
mysql> quit 
#7.重启mysql
/etc/init.d/mysqld restart 
#8.使用root用户重新登录mysql
mysql -uroot -p 
Enter password: <输入新设的密码newpassword>
