mysql 配置文件目录:/etc/my.cnf
root 密码为空的时候配置文件中下面这句:
|
GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY ‘123‘ WITH GRANT OPTION;
执行这句时候错误:
|
这个时候我们只需要
|
一下,在添加用户就OK了,
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY ‘123‘ WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
这个时候我们成功搞定了,再登录就可以了。
如果报错如下信息:
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
我们只要到/etc/yum.repo.s下面把packetxxxx.repo和redhat.repo两个文件删除掉,再启动就可以了,
