我在AWS EC2同一个实例下挂了2个wordpress，第一个一切正常，第二个除了主页，访问其他页面都提示“The requested URL was not found on this server”。原来是站点2缺少.htaccess文件。
我在AWS EC2同一个实例下挂了2个wordpress，第一个一切正常，第二个除了主页，访问其他页面都提示“The requested URL was not found on this server”。最开始以为是文件权限的原因，还花了不少时间，较为系统了解了下文件的操作权限（详情见博文《将AWS EC2中网页服务器目录/var/www/的权限设到最优》），仔细设置好文件(夹)权限后，并且再次检查apache2/sites-available/下的配置文件，还是不行。
最后在StackOverflow提问（问题在这里），今天得到回答，提示我检查.htaccess文件。一检查，才发现站点2压根就没有.htaccess文件，于是在站点2目录下创建之，内容如下：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
现在一切正常了。关于.htaccess，摘抄维基百科词条.htaccess部分内容如下：
A .htaccess (hypertext access) file is a directory-level configuration file supported by several web servers, that allows for decentralized management of web server configuration. They are placed inside the web tree, and are able to override a subset of the server’s global configuration for the directory that they are in, and all sub-directories.[1]
The original purpose of .htaccess—reflected in its name—was to allow per-directory access control by, for example, requiring a password to access the content. More commonly, however, the .htaccess files override many other configuration settings such as content type,character set, CGI handlers, etc.

您好，我还是出现这个问题，请问要怎么更新htaccess?
添加之后，在访问直接“您访问的网页出错了”【代码上传到主机里之后】
没有错误代码？
咋打不开页面
我这边没问题，你再试试？
