# 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。

查看日志

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;
+----------------+-------------+-------------------------------------------+

| 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

[Wed Apr 08 10:14:37.502684 2015] [:error] [pid 5510] [client 192.168.1.9:60334] PHP Warning:  mysql_fetch_array() expects parameter 1 to be resource, boolean given in /web/htdocs/index.php on line 24

[Wed Apr 08 10:18:46.821670 2015] [:error] [pid 5512] [client 192.168.1.9:60351] PHP Warning:  mysql_fetch_array() expects parameter 1 to be resource, boolean given in /web/htdocs/index.php on line 24

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。
