mysql下新建root权限用户
瞎折腾，把mysql的root权限弄没了。。。
现象如下：
mysql> select host,user,password from mysql.user; ERROR 1142 (42000): SELECT command denied to user 'root'@'localhost' for table 'user' mysql> grant all privileges on *.* to 'root'@'%' identified by "root" with grant option; ERROR 1045 (28000): Access denied for user 'root'@'' (using password: YES) mysql> show grants for root; ERROR 1141 (42000): There is no such grant defined for user 'root' on host '%' mysql> select * from mysql.user\G ERROR 1142 (42000): SELECT command denied to user 'root'@'localhost' for table 'user' mysql> SELECT USER(); +----------------+ | USER() | +----------------+ | root@localhost | +----------------+ 1 row in set (0.02 sec) mysql> ^CCtrl-C -- exit!
解决：创建带有root权限的用户，先跳过授权表dengl
root@clone1:/usr/local/mysql/bin 01:00:54>
sudo kill -9 `ps -ef|grep mysql|grep -v grep|awk '{print $2}'`
[1]+ 已杀死 /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
root@clone1:/usr/local/mysql/bin 01:01:38>
root@clone1:/usr/local/mysql/bin 01:01:38>
root@clone1:/usr/local/mysql/bin 01:01:38>
root@clone1:/usr/local/mysql/bin 01:01:39>

看见没？权限全是N。。。我们先把这条记录干掉，然后插入一条：
mysql> delete from mysql.user where user='root';
Query OK, 1 row affected (0.00 sec)
mysql> use mysql
Database changed
