<!DOCTYPE digest SYSTEM "../../../../dtd/article.dtd"> <article title="Converting rewrite rules" link="/en/docs/http/converting_rewrite_rules.html" lang="en"> <section title="A redirect to a main site"> <para> People who during their shared hosting life used to configure <i>everything</i> using <i>only</i> Apache’s .htaccess files, translate usually the following rules: <programlisting> RewriteCond %{HTTP_HOST} nginx.org RewriteRule (.*) http://www.nginx.org$1 </programlisting> in something like this: <programlisting> server { listen 80; server_name www.nginx.org nginx.org; if ($http_host = nginx.org) { rewrite (.*) http://www.nginx.org$1; } ... } </programlisting> </para> <para> This is a wrong, cumbersome, and ineffective way. The right way is to define a separate server for <url>nginx.org</url>: <programlisting> server { listen 80; server_name nginx.org; rewrite ^ http://www.nginx.org$request_uri?; } server { listen 80; server_name www.nginx.org; ... } </programlisting> </para> </section> <section> <para> Another example, instead of backward logic: all that is not <url>nginx.com</url> and is not <url>www.nginx.com</url>: <programlisting> RewriteCond %{HTTP_HOST} !nginx.com RewriteCond %{HTTP_HOST} !www.nginx.com RewriteRule (.*) http://www.nginx.com$1 </programlisting> you should define just <url>nginx.com</url>, <url>www.nginx.com</url>, and anything else: <programlisting> server { listen 80; server_name nginx.com www.nginx.com; ... } server { listen 80 default_server; server_name _; rewrite ^ http://nginx.com$request_uri?; } </programlisting> </para> </section> <section name="converting_mongrel_rules" title="Converting Mongrel rules"> <para> Typical Mongrel rules: <programlisting> DocumentRoot /var/www/myapp.com/current/public RewriteCond %{DOCUMENT_ROOT}/system/maintenance.html -f RewriteCond %{SCRIPT_FILENAME} !maintenance.html RewriteRule ^.*$ %{DOCUMENT_ROOT}/system/maintenance.html [L] RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^(.*)$ $1 [QSA,L] RewriteCond %{REQUEST_FILENAME}/index.html -f RewriteRule ^(.*)$ $1/index.html [QSA,L] RewriteCond %{REQUEST_FILENAME}.html -f RewriteRule ^(.*)$ $1/index.html [QSA,L] RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L] </programlisting> should be converted to <programlisting> location / { root /var/www/myapp.com/current/public; try_files /system/maintenance.html $uri $uri/index.html $uri.html @mongrel; } location @mongrel { proxy_pass http://mongrel; } </programlisting> </para> </section> </article>
