The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

skip-grant-tables下

GRANT ALL PRIVILEGES ON *.* TO helei IDENTIFIED BY 'MANAGER' WITH GRANT OPTION;

執行這句時候錯誤：
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

mysql> GRANT ALL PRIVILEGES ON *.* TO helei IDENTIFIED BY 'MANAGER' WITH GRANT OPTION;

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

這個時候咱們只須要

flush privileges

一下，在添加用戶就OK了，

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO helei IDENTIFIED BY 'MANAGER' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

這個時候咱們成功搞定了，再登陸就能夠了。

若是報錯以下信息：

Error: Cannot retrieve repository metadata (repomd.xml) for repository: InstallMedia. Please verify its path and try again
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

咱們只要到/etc/yum.repo.s下面把packetxxxx.repo和redhat.repo兩個文件刪除掉，再啓動就能夠了，
