I am trying to compile Nginx from source based on the original compiled Nginx server running on my DigitalOcean server ( Ubuntu-14.04 64x ) but with a few extra modules. I can get everything installed smoothly but I can not get it to start. I am sure the ini is correct because I copied the original source off the current running Nginx server [ Even though I see that Nginx now adds the ini when compiling fron source ].

Below is the [ lengthy process ] that I am performing - add sorry but I wanted to be thorough for those who are in need of the info ]. Because I am a newB to Nginx, I am sure I am missing something or just have it all wrong. If you may look over what I have done and see if you spot anything I need/need to change, I will greatly appreciate it. Thnx!

With the original Nginx server still running:

I check the current/running Nginx configuration so I can build the new Nginx instance the same but with the added modules:

nginx -V
# The out-put:

NOTE: The configure arguments below return errors during 'make' so I removed them. I don't know what they are - could this be related to my issue???

Moving on:

# So I don't have to sudo every line:
sudo bash

# Check for updates first thing:
apt-get update

# Install various prerequisites needed to compile Nginx:
apt-get install build-essential libgd2-xpm-dev lsb-base zlib1g-dev libpcre3 libpcre3-dev libbz2-dev libxslt1-dev libxml2 libssl-dev libgeoip-dev tar unzip openssl

# Create System users [ if it doesn't exist - but I see its there on DigitalOceans' Droplets all-ready ]:
adduser --system --no-create-home --disabled-login --disabled-password --group www-data

# Download NGINX
wget http://nginx.org/download/nginx-1.7.4.tar.gz
tar -xvzf nginx-1.7.4.tar.gz

# Then Google PageSpeed:
wget https://github.com/pagespeed/ngx_pagespeed/archive/release-1.8.31.4-beta.zip
unzip release-1.8.31.4-beta.zip

# cd into the PageSpeed Directory
cd ngx_pagespeed-release-1.8.31.4-beta/
# and add the PSOL files in there:
wget https://dl.google.com/dl/page-speed/psol/1.8.31.4.tar.gz
tar -xzvf 1.8.31.4.tar.gz

# Get back to the root directory:
cd

# I add the ngx_cache_purge module and will install the Nginx Helper plugin for WP later:
wget https://github.com/FRiCKLE/ngx_cache_purge/archive/2.1.zip
unzip 2.1.zip

# Add the headers-more-nginx-module:
wget https://github.com/openresty/headers-more-nginx-module/archive/v0.25.zip

# and the naxsi module for added security:
wget https://github.com/nbs-system/naxsi/archive/0.53-2.tar.gz
tar -xvzf 0.53-2.tar.gz

# cd to the new Nginx directory
cd nginx-1.7.4

# Set up the configuration build based on the current running Nginx config args and add my additional modules:

Next step:

I cd to root and I check the old Nginx folder locations and double checked the 'make' output to see that they are the same:

whereis nginx
#Output:
nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx

NOTE: Not sure about the '/usr/sbin/nginx' - Possible issue???

Next I copy the old /etc/nginx/nginx.conf, /etc/nginx/sites-available/default, /etc/nginx/sites-enabled/default, /etc/init.d/nginx to a text file locally for safe keeping to use in the new Nginx server.

Then stop the running Nginx server: service nginx stop , verify it's stopped: service --status-all and the output is: [ - ] nginx

To verify that there are two Nginx directories, I cd to: cd nginx* and the output is an error indicating there are two nginx folders - Cool Beans! :)

Now Install the new Nginx server: cd nginx-1.7.4 make install

I copy/create the files that I saved earlier to txt files in sites-available, the config, default and ini files then symlink them to sites-enabled, and so on.

And now to start the server: service nginx start

And this is where s#!+ hits the fan - Nada. I check to see if Nginx is running with service --status-all and its not. Also with nginx -V and its not installed??? I reboot the system too and still nothing. So I am not sure what is wrong here. The ini was copied over from the old server along with all the other config files after deleting the old files. When I opened the new compiled files, the nginx default data was present so I replaced them with my old original data prior to starting the new server for the first time.

Also to be safe, I rm /etc/nginx/sites-enabled/default and symlinked with ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default with no errors and I verified that the data was in the sites-enabled/default file.

I don't think the server really/fully installed because of the nginx -V result:

The program 'nginx' can be found in the following packages:
 * nginx-core
 * nginx-extras
 * nginx-full
 * nginx-light
 * nginx-naxsi
Try: apt-get install <selected package>

Do/should I apt-get install nginx-1.7.4 ?? Or what package do I use being that its a custom package and make install earlier did nothing??

If you need to see the conf files I copied over from the old to the custom server, LMK and I'll post them.

Again your help here would be appreciated!
