Probably you are setting a virtual host on one of the cloud providers. Read here few references on cloud computing provides
Configure Nginx with extra modules
The first step is to figure out which modules of Nginx you will be using. Read Nginx documentation and download all dependencies.
For example, I will download ngx_cache_purge from git and some few other Nginx modules
git clone https://github.com/phusion/passenger_apt_automation.git git clone https://github.com/FRiCKLE/ngx_cache_purge.git git clone https://github.com/openssl/openssl.git
Depending on which modules you will use probably you will need to install some libraries (depending on your operating system) as shown below.
apt-get install libxml2-dev apt-get install libxslt-dev apt-get install libgd2-xpm libgd2-xpm-dev
./configure --sbin-path=/usr/sbin/nginx --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --lock-path=/var/lock/nginx.lock --pid-path=/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit --with-ipv6 --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_spdy_module --with-http_sub_module --with-http_xslt_module --with-mail --with-mail_ssl_module --with-openssl=/usr/local/src/openssl-1.0.1j --add-module=/usr/local/src/passenger_apt_automation/debian_specs/nginx/modules/nginx-auth-pam --add-module=/usr/local/src/passenger_apt_automation/debian_specs/nginx/modules/nginx-echo --add-module=/usr/local/src/passenger_apt_automation/debian_specs/nginx/modules/nginx-upstream-fair --add-module=/usr/local/src/passenger_apt_automation/debian_specs/nginx/modules/nginx-dav-ext-module --add-module=/usr/local/src/ngx_cache_purge
Configure
The output of this command may be similar to:
Configuration summary + using system PCRE library + using OpenSSL library: /usr/local/src/openssl-1.0.1j + md5: using OpenSSL library + sha1: using OpenSSL library + using system zlib library nginx http scgi temporary files: "/var/lib/nginx/scgi"
Build Nginx and install
If the configure step was successfully finished, then you can try to build and install Nginx by following commands.
make make install
