WordPress Permalink更改，無法訪問頁面

Question

在我的WordPress 3.5.2站點的前端，我有三個按鈕：主頁，博客和示例頁面。當我的永久鏈接設置被設置爲Default，我可以訪問這三個頁面：

Home: http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com/ 

Blog: http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com/?page_id=13 

Sample Page: 
http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com/?page_id=2 

然而，當我改變了我的永久鏈接設置到Post name，並刷新瀏覽器，我無法訪問博客頁面和示例頁面。我收到以下錯誤：

Blog: http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com/blog 
Not Found 
The requested URL /blog/ was not found on this server. 

Sample Page: 
http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com/sample-page/ 
Not Found 
The requested URL /sample-page/ was not found on this server. 

在WordPress中的Settings -> Permalink Settings，我也得到這個消息：

If your .htaccess file were writable, we could do this automatically, but it isn’t so these are the mod_rewrite rules you should have in your .htaccess file. Click in the field and press CTRL + a to select all.

當我檢查我的權限.htaccess文件，我得到了644，所以我它改爲666和消息消失（我改回644）

[ec2-user@ip-xx-xxx-xxx-xx html]$ ls -l .htaccess 
-rw-r--r-- 1 root root 258 Jul 25 21:49 .htaccess 
[ec2-user@ip-xx-xxx-xxx-xx html]$ sudo chmod 666 .htaccess 

我仍然可以訪問我的家庭p將固定鏈接設置更改爲Post name後的年齡。我不知道這有什麼與我的問題，但我對我的亞馬遜EC2微實例子目錄（XXX）安裝在我的WordPress網站，我改變了WP的常規設置如下：

WordPress Address (URL): http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com/xxx 

Site Address (URL): http://ec2-xx-xxx-x-xxx.compute-1.amazonaws.com 

Answer 1

我發現這可以通過搜索「permalinks htaccess amazon ec2」，它可能有所幫助：http://guiem.info/permalinks-on-wordpress-amazon-ec2/

Answer 2

在Wordpress安裝的根目錄下創建一個.htaccess文件。如果你想的WordPress來自動執行

# BEGIN WordPress 

<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteBase/
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule . /index.php [L] 
</IfModule> 

# END WordPress 

，然後使用chmod更改文件權限爲777 - 然後添加以下。
