我是新手。我使用的是Ubuntu 14.04.2，我在目录/var/www/example.com/.htaccess中创建了一个.htaccess文件。但是我的脚本hello.php不工作，而是返回error 500 internal server error。
第一步:
1. enabling mod-rewrite using
sudo a2enmod rewrite
2. change config
sudo nano /etc/apache2/sites-available/000-default.conf
<Directory "/var/www">
AllowOverride All
</Directory>
3. restart apache2
sudo service apache2 restart
4. create .htaccess in sub folder
sudo nano /var/www/example.com/.htaccess
我想要。htaccess隐藏。php如"www.example.com/aaa.php"到"www.example.com/aaa/"
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
## hide .php extension
# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}'s([^.]+)'.php [NC]
RewriteRule ^ %1 [R,L,NC]
## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [L]
您可能想要尝试一些事情。首先，您没有在重定向中包含尾斜杠。其次，针对%{REQUEST_FILENAME}变量的-f检查将不起作用，因为它是模糊的，并且将处理路径信息。所以尝试:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
## hide .php extension
# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}'s([^.]+)'.php [NC]
RewriteRule ^ %1/ [R,L,NC]
## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^(.*?)/?$ $1.php [L]
