PHP页面空白 无法加载mysql的解决办法
睡梦中被网站监测(点击进入这里有很多提供免费网站监测的网站,我使用的是国外的,每分钟监测一次,实时提醒,避免网站长时间挂掉。)短信给吵醒了,网站无法正常打开了,无奈起床。
所有网站提示Service Unavailable,看日志发现有加载7i24防盗链文件错误的日志,先不查原因,卸载了先说,卸载后静态页面正常,但是php页面不行,全是空白页面,重启iis、mysql都无果,写个php简单页面测试php发现正常,看来是无法连上mysql,上网搜索解决方法,搜到以下几种方法:
1. extension_dir = 和PHP实际的ext目录不一致。
2. 没有把PHP目录和ext目录添加到环境变量中。
3. extension=php_mysql.dll等前的;注释没去掉。
4. Zend安装目录和php.ini中Zend指定的目录不一致。
5、把libmySQL.dll复制一个到:c:\windows\system32下..然后重启IIS
看的眼花缭乱吧,我一一都试过了,还是不行。然后重启服务器,不行。重装php mysql还是不行,到此有点崩溃了。不过不能崩溃,还得继续查,查到一篇文章里提到 phpinfo() 里 Loaded Configuration File C:\WINDOWS\php.ini ,那篇文章提到是php.ini的问题,但是我这不会是php.ini,因为我已经之前的恢复过了。不过我打开phpinfo()页面(),看到 Loaded Configuration File (none) ,显然根本就没有加载到php.ini,这时候我想到了权限,赶快给其添加了users读取权限(不行的话可以再加上guests),重启iis,ok了。
所以除了上面5条,可以再加个第6条:
6.检查php.ini权限,给其users(guests)读取、读取和运行权限。
环境:win2003 、iis
