Nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server, originally written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, Mail.Ru, VK, and Rambler.
Nginx was once the default webserver for OpenBSD and was included in Base. Nginx was imported for OpenBSD 5.1 in September 2011 and was meant as a replacement for the Apache webserver which had been the default webserver since March of 1998. In November 2015, the httpd webserver was included in OpenBSD for version 5.6. This led to the removal of Nginx from OpenBSD Base for versions after that. Since then the best way to install Nginx on OpenBSD is to use ports.
Using ports on OpenBSD is transparent in that you use the same command to install Base packages. The pkg_add utility checks but it does require the location of the ports. The pkg_add utility will use the $PKG_PATH variable as the location of the ports.
Set the $PKG_PATH with:
export "PKG_PATH=https://cdn.openbsd.org/pub/OpenBSD/`uname -r`/packages/`arch -s`/"
To make this location permanent, you can add the export command to your .profile file so that it will be loaded during login.
Now that the location is set, the Nginx package can be installed with pkg_add, just like you would install any other package.

Next, add the following line to /etc/rc.conf.local, creating the file when it doesn't exist.
Execute the following command as root to make Nginx start automatically on boot.
rcctl enable nginx
The default configuration will let the Nginx webserver listen on port 80 and will serve files from the /var/www/htdocs/ directory.
The configuration for Nginx is located in /etc/nginx/nginx.conf.
As a quick test, create a file called index.html in the document root:
Add some HTML:
<html> <body> Hello World </body> </html>
Start the webserver.
rcctl start nginx
If you browse to http://IP_ADDRESS/, you should be greeted with the “Hello World” message.
