Une partie de la documentation a t traduite du russe vers langlais. Ses sources sont disponibles sous une licence de type BSD. Nginx est un systme asynchrone en par opposition aux serveurs synchrones o chaque requte est traite par un processus ddi. Au lieu dexploiter une architecture parallle et un multiplexage temporel des tches par le systme dexploitation, Nginx utilise les changements dtat pour grer plusieurs connexions en mme temps  le traitement de chaque requte est dcoup en de nombreuses mini tches et permet ainsi de raliser un multiplexage efficace entre les connexions. Afin de tirer parti des ordinateurs multiprocesseurs, plusieurs processus peuvent tre dmarrs. Ce choix darchitecture se traduit par des performances trs leves, mais galement par une charge et une consommation de mmoire particulirement faibles comparativement aux serveurs HTTP classiques, tels quApache.

Chaque module peut agir comme un filtre sur le contenu en entre, en sortie ou intermdiaire proxy par le biais de nombreuses callbacks. Ainsi, titre dexemple, un contenu dynamique peut tre compress la vole par le module  gzip  avant envoi. Ces modules sont lis au serveur lors de la compilation. Nginx ne supporte pas les bibliothques dynamiques partages. Tengine, le fork de nginx de Taobao a ajout cette fonctionnalit, qui na pas t reporte sur nginx5. Le noyau sappuie sur des structures de donnes minimales, mais optimales, visant rduire le nombre dappels systme, en particulier pour tout ce qui a trait lallocation de mmoire. Diffrents mcanismes de signalisation peuvent tre utiliss afin dexploiter au mieux le systme dexploitation par exemple  epoll sous Linux et kqueue sous BSD. Larchitecture asynchrone soulage lordonnanceur du systme dexploitation et favorise lutilisation des caches ou dudes processeurs. Un processus matre contrle le ou les processus serveurs, de cette faon il est possible de changer la configuration ou de mettre jour le fichier excutable du serveur sans avoir arrter le service HTTP. Nginx fonctionne sous les systmes dexploitation GNULinux, BSD, Mac OS X et Solaris  partir de la version avance 0. Nginx est galement disponible pour Microsoft Windows. Outre le fait dtre un serveur HTTP, Nginx peut tre configur pour tre un proxy inverse en anglais  reverse proxy Web et un serveur proxy de messagerie lectronique IMAP POP3. Lutilisation la plus frquente de Nginx est de le configurer comme un serveur Web classique pour servir des fichiers statiques et comme un proxy pour les requtes dynamiques typiquement achemines en utilisant une interface Fast.

Im not going to get into a lot of details about how to install and configure either http server from scratch. This article is primarily going to be food for thought for those who may want or need to configure nginx along side an existing apache httpd configuration. If you would rather ditch Apache all together, consider reading Martin Fjordvalds Nginx Primer 2 From Apache to Nginx. Side by Side. In some cases you may need to run both Apache httpd and Nginx on port 8. Such a situation can be a server running CpanelWhm and as such doesnt support nginx, so you wouldnt want to mess with the apache configuration at all. To do this you have to make sure Apache and Nginx are bound to their own IP adddress, In the event of WHMCpanel based webserver, you can Release an IP to be used for Nginx in WHM. At this time I am not aware of a method of reserving an IP, and automatically forcing Apache to listen on a specific set of IPs in a control panel such as Direct. Admin or Plesk. But the link above will show you how with WHMCpanel. Normally Apache will be listening on all interfaces, and such you may see a line like this in your httpd. Instead youll need to tell apache to listen on a specific IP you can have multiple Listen lines for multiple IPsWhen you change Apache to listen on specific interfaces some Virtual. Host may fail to load if they are listening on specific IPs themselves. The address option in lt Virtual. Host addr port addr port only applies when the main server is listening on all interfaces or an alias of such. If you do not have an IP Listed in your lt Virtual. Host tag, then you do not need to worry bout this. Otherwise make sure to remove the addr port from the Virtual. Host tag. Make sure to update the Name. Virtual. Host directive in Apache for name based virtual hosts. Once you have apache configured to listen on a specific set of IPs you can do the same with nginx. Now that both servers are bound to specific IPs, both can then be started up on port 8. From there you would simply point the IP of the domain to the server you wish to use. In the case of WHMCpanel you can either manually configure the DNS entry for the domain going to nginx in WHM, or you can use your own DNS such as with your registrar to point the domain to the specific IP. Using the latter may break your mailftp etc configurations if the DNS entries are not duplicated correctly. Though normally if you are setting up Nginx side by side with apache, youll have your domain configurations separate from the rest of the system. The above paragraph only applies if the domain you are using has already been added by cpanelwhm and you wish to have it served by nginx exclusively. Scroll down for PHP considerationsApache behind Nginx. If you are using a control panel based hosting such as cpanelwhm, this method is not advised. Most of the servers configuration is handled automatically in those cases, and making manual changes will likely lead to problems plus you wont get support from the control panel makers or your hosting provider in most cases. Using Nginx as the primary frontend webserver can increase performance regardless if you choose to keep Apache running on the system. One of Nginxs greatest advantage is how well it serves static content. It does so much more efficiently than Apache, and with very little cost to memory or processing. So placing Nginx in front will remove that burdern off Apache, leaving it to concentrate on dynamic request or special scenarios. This method is also popular for those who dont want to use PHP via fastcgi, or install a separate php fpm process. First thing that needs to be done is to change the interface apache listens on Above we bind Apache to the localhost on an alternate port, since only Nginx on the same machine will be communicating with Apache. Note Since Nginx needs to access the same files that Apache serves, you need to make sure that Nginx is setup to run as the same user as apache, or to make sure that the Nginxs selected user group has permission to read the web documents. Often times the webroot is owned by nobody or www data and Nginx likewise can be setup to run as those users. Then in Nginx listening on port 8. IPs, your choice we would need to configure Nginx to serve the same content. Take for example this virtual host in an apache configuration lt Virtual. Host. Document. Rootusrlocalwwwmydomain. Server. Name mydomain. Server. Alias www. Custom. Log varloghttpdmydomainaccess. Error. Log varloghttpdmydomainerror. Virtual. Host In Nginx the equivalent server configuration would be server. The above would serve all static content from the same location, however PHP will simply come back as PHP source. For this we need to send any PHP requests back to Apache. Fast. CGI process. Apache the actual IP of the client being forwarded Apache requires modproxy http bit. Most Apache 2. 0 servers have modproxy configured already. X Real IP remoteaddr. X Forwarded For remoteaddr. Host header so that apache knows which v. Host to serve the host variable is automatically set to the hostname Nginx is responding to. Host host. And now we pass back to apache if youre using a side by side configuration the IP can be changed to apaches bound IP at port 8. You can remove the log directives if you wish to log any attempts at a client trying to access a hidden file. In the case of rewriting modrewrite with apache behind nginx you can use an incredibly simple directive called tryfiles. Heres the same code as above, but when changes made so that any files or folder not found by nginx gets passed to apache for processing useful for situations like Word. Press, or. htaccess based rewrites when the file or folder is not caught by Nginxserver. X Real IP remoteaddr. X Forwarded For remoteaddr. Host host. proxypass http 1. The rest is the same as the configuration above. With the above configuration, any file or folder that exists will be served by Nginx the php block will catch files ending in. In some cases you may wish for everything to be passed to Apache unless otherwise specified, in which case you would have a configuration such as this server. X Real IP remoteaddr. X Forwarded For remoteaddr. Host host. proxypass http 1. Example 1 Specify a folder and its content To serve everything under css from Nginx only. Example 2 Specify a Reg. Ex pattern such as file extensions Serve certain files directly from Nginx. Nginx error page as opposed to apaches own error page. Personally I prefer to leave Nginx to handle everything, and specify exactly what needs to be passed back to Apache. But the last configuration above would more accurately allow. The css folder or any files found by the other location block would be served directly by nginx regardless if theres an. Apache processes. PHP Considerations. If you are not familiar with Nginx, then it should be noted that Nginx does not have a PHP module like apaches modphp, instead you either need to build PHP with FPM ie php fpmfastcgi, or you need to pass the request to something that can handle PHP. In the case of using Nginx with Apache you essentially have two choices 1 Compile and Install PHP FPM, thus running a seperate PHP process to be used by Nginx.
