系统linux+php5.3
tp3.1.2
按照TP的手册说修改 httpd.conf 的 mod_rewrite.so 模块分号
然后还有 AllowOverride None 将None改为 All （这个地方在httpd.conf里面有5处，我都修改成了All，不知道是否是正确的，还是只是需要修改一处就可以了？）
URL_MODEL设置为2 这个在配置文件里面也设置成了2，然后在写一个 ..htaccess 放在网站的根目录,内容如下
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
然后重新启动httpd，结果提示 500 Internal Server Error ，开始我以为是我apache的问题，最后我看其他的网站又正常(这台linux有多个网站)，最后把 .htaccess删除以后打开网站又恢复正常，如果在放.htaccess又出现问题，那就可以说明.htaccess有问题了，是不是这个里面的内容有问题呢，还是需要php.ini在设置其他的呢
回复讨论(解决方案)
<IfModule mod_rewrite.c>RewriteEngine on#如果目录存在就直接访问目录不进行RewriteRuleRewriteCond %{REQUEST_FILENAME} !-d#如果文件存在，就直接访问文件，不进行下面的RewriteRule.(不是文件或文件不存在就执行重写)RewriteCond %{REQUEST_FILENAME} !-f#所有找不着实际路径的文件，统一交给index.php处理RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]</IfModule> TP 自己就带有 .htaccess

我按照这个BLOG的地址设置了，也就是大概意思是 httpd.conf里面要单独设置，比如一个网站
<VirtualHost *:80> LoadModule rewrite_module modules/mod_rewrite.so //我写在这里了， ServerAdmin webmaster@dt.e.com DocumentRoot /web/xx.com ServerName xx.com ErrorLog logs/errun-error_log CustomLog logs/acrun-access_log common</VirtualHost>
单独一个网站就需要单独开启一个模块吗，不能全局配置吗，我按照这样的修改以后在重新启动httpd.启动是可以，但是报了一个错误
然后问题依旧～
只要全局有一个就行了
我这修改以后网站根目录没有放.htaccess文件，这样提示，根目录放了也是提示400 Bad Request
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"><html><head><title>400 Bad Request</title></head><body><h1 id="Bad-nbsp-Request">Bad Request</h1><p>Your browser sent a request that this server could not understand.<br /></p></body></html>
首页是500，我刚才是直接访问的模块 显示400,
然后在后面加 xx.com/index.php 访问也不行了
只要全局有一个就行了
我找到原因了，是默认创建.htaccess的时候权限问题，因为我是root登录的，所以创建这个文件的权限是ROOT，我有把它设置成
777的权限，但还是一样，刚才我试着修改成此网站的用户组和用户，然后刷新就可以了。
