問題來了，到瀏覽器輸入192.168.1.9

其它的就不顯示了。

查看日志

#?less?error_log

好吧，數據庫每打開

#?service?mysqld?start????????#設置過開機啟動，不知道為什么沒有用

再到瀏覽器刷新還是沒有用

進入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???|?????????????|???????????????????????????????????????????| +-------------+-------------+-------------------------------------------+

怎么會沒有root用戶，www.crwolf.com主機，第一次就創建了，可能不小心給刪了，好吧，再重新創建

mysql>?create?user?'root'@'www.crwolf.com'?identified?by?'welcome'; ERROR?1396?(HY000):?Operation?CREATE?USER?failed?for?'root'@'www.crwolf.com'

你妹，這又是怎么回事，網上找了好久，說是bug了，解決方法：把要創建的用戶刪除一次，再創建，別忘記flush

mysql>?drop?user?'root'@'www.crwolf.com';????#都沒有這個，還要再刪除，挺郁悶的 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??????|?????????????|???????????????????????????????????????????| +----------------+-------------+-------------------------------------------+

這次有用戶了吧，再刷新頁面，怎么還是剛剛的頁面，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

登陸數據庫的用戶沒有數據庫的權限(這個只是我的，可能還有別的原因)，到mysql授權。不解處：root還沒有權限？

mysql>?use?mysql? Database?changed mysql>?grant?select?on?table1.test?to?root??; Query?OK,?0?rows?affected?(0.00?sec)

再去刷新頁面，終于好了。
