In this blog, we will Setup Nginx as a Reverse proxy for Apache Server running on the same server

Requirement:

1. One Ubuntu Server
2. Apache installed
3. Nginx installed

Install Apache2

sudo apt-get install apache2

sudo service apache2 start

By default, it is running on port 80, open your browser http://yourip

You will see the default page of apache ubuntu server.

Now to check this url is running on which server

1. Right click on your page -> Inspect -> Click on Network -> make sure All is selected as shown below

2. Reload the page -> you will see your ip -> click on your ip ->Click Headers

You will see that is running on apache server

Edit Apache default configuration

1. sudo vi /ect/apache2/ports.conf and make your configuration like this or you can use the port as per your requirement

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 8080

<IfModule ssl_module>
 Listen 8443
</IfModule>

<IfModule mod_gnutls.c>
 Listen 8443
</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

2. sudo vi /etc/apache2/sites-enabled/000-default.conf

Change the VirtualHost to run on port 8080. All other setting remains same

<VirtualHost 127.0.0.1:8080>

3. Restart Apache Server

NGINX Configuration

1. sudo apt-get install nginx
2. sudo service nginx start
3. Open your browser and you will see the default NGinx home page
4. NGinx also runs on default port 80

Configure it to use as a proxy for apache server

1. cd /etc/nginx/conf.d
2. sudo vi proxy.conf and make sur eto delete the default file

server {
listen 80;
root /usr/share/nginx/html;
index index.html;
location / {
 proxy_pass http://127.0.0.1:8080/;
}
}

3. sudo nginx -t

ubuntu@ip-11–0–11–165:/etc/nginx/conf.d$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

4. Restart or reload nginx

5. Now browse url — http://yourip — this will redirect to apache home page and do the above steps to check which server it is running on , you will see the nginx server

Below is my security group setting for this EC2 instance — Make sure port 80 is open
