Install Nginx on Openbsd

1. Git clone https://github.com/nginx/nginx and cd into the nginx directory

   git clone https://github.com/nginx/nginx && cd nginx

2. Create "configure" script for building nginx

   #!/bin/sh

   test -d $NGX_OBJS || mkdir -p $NGX_OBJS

   echo "#define NGX_CONFIGURE \"$NGX_CONFIGURE\"" > $NGX_AUTO_CONFIG_H
   
   
   if [ $NGX_DEBUG = YES ]; then
    have=NGX_DEBUG . auto/have

   if test -z "$NGX_PLATFORM"; then
    echo "checking for OS"

            NGX_PLATFORM=win32
        ;;
    esac
   
   else
    echo "building for $NGX_PLATFORM"
    NGX_SYSTEM=$NGX_PLATFORM
   fi

   if [ "$NGX_PLATFORM" != win32 ]; then

   esac

3. Create the build.sh script with the contents below

   #! /bin/sh
   ./configure --sbin-path=/usr/local/sbin/nginx \
   --conf-path=/etc/nginx/nginx.conf \
   --pid-path=/var/run/nginx.pid \
   --with-http_ssl_module \
   --http-log-path=/var/log/nginx.log \
   --error-log-path=/var/log/nginx-error.log \
   --http-fastcgi-temp-path=/var/tmp/fastcgi_tmp \
   --http-proxy-temp-path=/var/tmp/proxy_tmp \
   --http-client-body-temp-path=/var/tmp/client_body_temp \
   --with-http_stub_status_module \
   --user=www --group=www \
   --with-http_auth_request_module \
   --with-http_dav_module \
   --with-http_image_filter_module=dynamic \
   --with-http_gzip_static_module \
   --with-http_gunzip_module \
   --with-http_perl_module=dynamic \
   --with-http_realip_module \
   --with-http_slice_module \
   --with-http_ssl_module \
   --with-http_stub_status_module \
   --with-http_v2_module \
   --with-http_xslt_module=dynamic \
   --with-mail=dynamic \
   --with-stream=dynamic \
   --with-stream_ssl_module \
   --with-stream_ssl_preread_module \
   --without-pcre2

4. Install needed dependencies to build

   doas pkg_add pcre libxslt gd

5. Build nginx by running the build.sh script we created
6. Once the build completes we can go ahead and run a "make install" to install the build

7. Create rcctl script in /etc/rc.d/nginx and then enable execute "chmod +x /etc/rc.d/nginx"

   #!/bin/ksh
   
   daemon="/usr/local/sbin/nginx"
   
   . /etc/rc.d/rc.subr
   
   pexp="nginx: master process ${daemon}${daemon_flags:+ ${daemon_flags}}"
   rc_stop_signal=QUIT
   
   rc_configtest() {
   ${daemon} ${daemon_flags} -t
   }
   
   rc_cmd $1

8. Enable and start nginx service

   doas rcctl enable nginx && doas rcctl start nginx

9. At this point we should be able to open nginx on our browser "http://localhost" and receive the welcome page

Nginx is now deployed and ready to be used on our shiny new OpenBSD 7.4 install. In the next few posts I will cover some very basic configuration files for using nginx as a reverse proxy.
