How to configure Apache on Ubuntu 14.04 if Nginx is already installed

Question

I followed the Tutorial on Digital Ocean and installed LEMP server successfully.

Then I read about reverse-proxy using Nginx and APache for hosting multiple websites on the same droplet .

Since I have Big fat droplet , I would like to host two Laravel Based APP on the same droplet .

So using this tutorial I Installed apache2 LINK

But unluckily apache is not running

$ sudo service apache2 reload
 * Reloading web server apache2                                               *
 * Apache2 is not running

So I did

 sudo netstat -tlpn

and got this table

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         Stat     e       PID/Program name
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LIST     EN      5377/nginx
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LIST     EN      1233/sshd
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LIST     EN      3529/mysqld
tcp6       0      0 :::80                   :::*                    LIST     EN      5377/nginx
tcp6       0      0 :::22                   :::*                    LIST     EN      1233/sshd

I am a windows user and I have no Idea about how to fix this .

Can any one help me out .

Thanks,

Nginx runs on port 80 and that's ok. The default port for the Apache httpd is port 80, too and that's a problem.

Reconfigure Apache httpd

• Use port 8080 for your Apache httpd. Open ports.conf

  sudo nano vi /etc/apache2/ports.conf
  

  and replace

  Listen 80
  

  with

  Listen 8080
  

  Do the same for virtual hosts, if necessary.

• Restart Apache httpd

  sudo systemctl restart apache2
  

  or on Trusty with

  sudo service apache2 restart
  

• Check the output of netstat

  $ sudo netstat -tulpn | grep apache2
  tcp6   0  0 :::8080   :::*  LISTEN  22769/apache2
  

  And yes, also with the output above, httpd is listening on tcp port 80.

• Reconfigure nginx to work as proxy and use your Apache httpd as backend, e.g. for port 80 by editing of /etc/nginx/sites-available/default

  sudo nano /etc/nginx/sites-available/default
  

  and add the proxy settings below in the location section

  proxy_pass http://127.0.0.1:8080;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto http;
  proxy_set_header X-Forwarded-Port 80;
  proxy_set_header Host $host;
  

• Restart nginx

  sudo systemctl restart nginx
  

  or on Trusty with

  sudo service nginx restart
  

• Check the output of netstat

  $ sudo netstat -tulpn | grep -P 'nginx|apache2'
  tcp  0  0 0.0.0.0:80  0.0.0.0:*  LISTEN  22973/nginx -g daem
  tcp6 0  0 :::80       :::*       LISTEN  22973/nginx -g daem
  tcp6 0  0 :::8080     :::*       LISTEN  22769/apache2 
  

And it's a good idea to configure httpd to listen only on 127.0.0.1.

Long story short - you have to run apache listening on different port (Listen), since port 80 is already in use by nginx.
