Nginx is a great alternative to apache & has been gaining popularity in recent times. Though Nginx has been known to being a web server with less modules/add-ons & more complex settings than apache but if you are hosting a single website that you want to work at fast speed, than Nginx is right fit for you. This tutorial details process to install nginx server but let's first discuss nginx in brief.

Nginx is an open source has been known to address some of performance-related issues that apache has. It uses an event driven design, as opposed to process driven design used by apache which causes apache to slow down under heavy loads as it needs to create new processes which causes increased memory consumption. Worker processes can be configured for Nginx (each worker process is equal to one cpu) & each worker process can handle thousand concurrent connections.

In this tutorial, we will learn to install Nginx server, but before we move onto install Nginx server, we need to perform the following steps.

1- Remove Apache

If you are using an old installation on apache server, then remove it as both nginx & apache uses same ports i.e. 80 & 443. To remove apache

$ yum remove httpd

2- Entry for our virtual host in /etc/hosts

We need to create an entry for out virtual host ( in /etc/hosts,

$ vi /etc/hosts           

3- Epel or Nginx repositories enabled

Since Nginx is available with default RHEL/CentOS repositories, we either need to enable official Nginx repository or Epel repository

Nginx Repository

To enable Nginx repository, create a file named 'nginx.repo' in '/etc/yum.repos.d' & add the following repo information

$ vi /etc/yum.repos.d/nginx.repo

[nginx] name=nginx repo

Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.

Epel Repository


$ dnf install


$ rpm -Uvh

RHEL/CentOS 6 (64 Bit)

$ rpm -Uvh

RHEL/CentOS 6 (32 Bit)

$ rpm -Uvh

Install Nginx server

Once the Nginx/Epel repository has been enabled, installation can be easily done with yum. To install nginx server, run

$ yum install nginx

Now start the nginx service & also enable it after reboot,

$ systemctl start nginx
$ systemctl enable nginx

We can also test the installation by opening web browser & entering IP address/FQDN of our server

http://IPAddress or FQDN/

& a test page will open.


Configuring Virtual hosts (aka Server Blocks)

Like apache, document root directory for nginx is also '/var/www/html' & it works fine if hosting a single wesbite (virtual host) but when deploying multiple websites, it is advisable to create our custom document directory. So, we will first create a document directory for our website ''

$ mkdir -p /var/www/newhost/html

& provide necessary permissions i.e. 755 to all directories created in /var/www

$ chmod 755 /var/www

Next, create an index.html file to greet website users,

$ cd /var/www/newhost/html
$ echo "Welcome to" > index.html

Last thing now to configure is to create an entry for the website/virtual host in configuration file i.e. '/etc/nginx/conf.d/virtual.conf' . Open the file & create an entry for our host,

$  vi /etc/nginx/conf.d/virtual.conf

server {
listen       80;
#    listen       *:80;

location / {
root   /var/www/;
index  index.html index.htm;

Save file & exit it. Lastly restart nginx services to implement the changes made to configuration file.

$ systemctl restart nginx

Now open web browser & enter '' in the address bar. This will open our website

Note - If we need to create more than one virtual host, repeat the same process. Create a document root directory, place website files in it, create an entry for it in virtual.conf & restart services.
