# service httpd24 restart问题来了，到浏览器输入192.168.1.9
其它的就不显示了。

好吧，数据库每打开
# service mysqld start #设置过开机启动，不知道为什么没有用
再到浏览器刷新还是没有用
进入mysql
# mysql mysql> use mysql Database changed mysql> SELECT host,user,password FROM user; +-------------+-------------+-------------------------------------------+ | host | user | password | +-------------+-------------+-------------------------------------------+ | localhost | root | *DF216F57F1F2066124E1AA5491D995C3CB57E4C2 | | 127.0.0.1 | root | | | ::1 | root | | | localhost | | | +-------------+-------------+-------------------------------------------+
怎么会没有root用户，www.crwolf.com主机，第一次就创建了，可能不小心给删了，好吧，再重新创建
mysql> create user ‘root‘@‘www.crwolf.com‘ identified by ‘welcome‘; ERROR 1396 (HY000): Operation CREATE USER failed for ‘root‘@‘www.crwolf.com‘
你妹，这又是怎么回事，网上找了好久，说是bug了，解决方法：把要创建的用户删除一次，再创建，别忘记flush
mysql> drop user ‘root‘@‘www.crwolf.com‘; #都没有这个，还要再删除，挺郁闷的 Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> create user ‘root‘@‘www.crwolf.com‘ identified by ‘welcome‘; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> SELECT host,user,password FROM user; +----------------+-------------+-------------------------------------------+ | host | user | password | +----------------+-------------+-------------------------------------------+ | localhost | root | *DF216F57F1F2066124E1AA5491D995C3CB57E4C2 | | 127.0.0.1 | root | | | www.crwolf.com | root | *DF216F57F1F2066124E1AA5491D995C3CB57E4C2 | | ::1 | root | | | localhost | | | +----------------+-------------+-------------------------------------------+
这次有用户了吧，再刷新页面，怎么还是刚刚的页面，再看日志
# less error_log

登陆数据库的用户没有数据库的权限(这个只是我的，可能还有别的原因)，到mysql授权。不解处：root还没有权限？
mysql> use mysql Database changed mysql> grant select on table1.test to root ; Query OK, 0 rows affected (0.00 sec)
再去刷新页面，终于好了。
