How to use Apache webserver and Nginx webserver in single instance

Run the following commands to start and enable your Apache service.

[root@linuxhelp ~]# service httpd start
Starting httpd:
[root@linuxhelp ~]# chkconfig httpd on

Go to httpd.conf configuration file and provide your domain name as your server name. Save the changes and restart your apache service.

[root@linuxhelp ~]# vim /etc/httpd/conf/httpd.conf
ServerName ns2.linuxhelp.com:80

Move to Apache root directory and create index.html file.

[root@linuxhelp ~]# cd /var/www/html/
[root@linuxhelp ~]# vim index.html
Apache service is running

[root@linuxhelp ~]# service httpd restart
Stopping httpd:                                           [  OK  ]
Starting httpd:                                             [  OK  ]

Switch over to the browser and provide the machine' s IP or domain name. The screen will show as below.

Now install the NGINX service by running the following command.

[root@linuxhelp ~]# yum install nginx

  nginx-mod-http-xslt-filter.x86_64 0:1.10.2-1.el6                              
  nginx-mod-mail.x86_64 0:1.10.2-1.el6                                          
  nginx-mod-stream.x86_64 0:1.10.2-1.el6                                       
Complete!

Try starting the NGINX service by running the following command.

[root@linuxhelp ~]# service nginx start
Starting nginx: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
                                                           [FAILED]

It has failed because the Apache service is using port 80. Now move to your NGINX configuration file and create a configuration file named default.conf using vim editor.

[root@linuxhelp ~]# vim /etc/nginx/conf.d/default.conf

Change the listen port to 8085.

Save the changes in the file and try to restart the NGINX service.

[root@linuxhelp ~]# service nginx start
Starting nginx:                                            [  OK  ]
[root@linuxhelp ~]# chkconfig nginx on

Go to its root directory and list the files in the directory. Create a file named index.html using vim editor.

[root@linuxhelp ~]# cd /usr/share/nginx/
[root@linuxhelp nginx]# ls -l
total 8
drwxr-xr-x 2 root root 4096 Sep  7 10:35 html
drwxr-xr-x 2 root root 4096 Sep  7 10:35 modules
[root@linuxhelp nginx]# cd html/
[root@linuxhelp html]# vim index.html

[root@linuxhelp ~]# vim index.html
Nginx service is working
