What WWW servers does DirectAdmin support?

DirectAdmin has support for a variety of WWW servers. To check which one is in use, and possible options:

cd /usr/local/directadmin/custombuild/
./build opt_help | grep webserver
>webserver: apache, nginx, nginx_apache, litespeed, openlitespeed. Current value: openlitespeed. Default value: apache.


  • apache is the most popular. This is the Apache HTTP server from https://httpd.apache.org/open in new window
  • nginx is high performance open-source web server, great for static files but has limitations for .htaccess files, so it may require manual adjustments. https://www.nginx.com/open in new window
  • nginx_apache is a powerful reverse proxy where nginx serves static files, while dynamic files and .htaccess are processed by Apache. It's a good choice without needs to modify existing scripts or mod_rewrite rules. It mainly benefits slow connections.
  • litespeed is a commercial web server. It is a drop-in replacement for Apache from LiteSpeed Technologiesopen in new window. It provides faster response times and reduced server load average when compared with Apache.
  • openlitespeed is the open source edition of the LiteSpeed Web Server, and contains all essential features and benefits from it, with some limitationsopen in new window. It's not a drop-in replacement for Apache though, due to lack of full .htaccess support and different configuration syntax.

Every system may have specific needs, a comparison table:

Apacheindustry standard, highly customizablehigh memory usage and slow for static filesYES
Nginxgreat performance and response timeshas no support for .htaccess, needs manual configuration for URL rewritesNO

OpenLiteSpeed might be a great option for WordPress-only hosting or other CMSs that have the LSCache caching plugin.
