Introduction
NGINX is a web server with light resource consumption patterns. A main difference from Apache is that NGINX does not needs to spawn new processes or threads for each request.
In this tutorial we will show you how to install NGINX with yum on a CentOS server. You must have root privileges to be able to execute the installation commands.
Install EPEL
Linux package manager YUM does not include the latest version of NGINX in its default repository. Therefore, installing Extra Packages for Enterprise Linux (EPEL) will make sure it always stays up to date.
sudo su -c 'rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm'
Now EPEL packages are installed and ready to use.
Install NGINX
In the terminal window, type the following command:
sudo yum install nginx -y
You will get an output similar to this:
Loaded plugins: product-id, rhnplugin, security, subscription-manager Updating certificate-based repositories.

Set NGINX to start at boot time:
chkconfig nginx on
Now, everytime you reboot your server, NGINX will be started automatically.
Start NGINX.
Once you have installed NGINX, it's time to manually start it:
sudo /etc/init.d/nginx start
Test NGINX
Now that is is installed you can direct your web browser to your server or VPS IP address.
http://12.34.56.789
You should get a page that says "Welcome to nginx” This confirms it is all set and ready to serve your web content.
NGINX Configuration and Log files (optional):
You can further customize the settings of your NGINX web server by changing the settings of its configuration files, you can also check the logs for any error debugging or simple maintenance routines. This files are:
- -configuration directory: /etc/nginx/
- -SSL and vhost config directory: /etc/nginx/conf.d/
- -log file directory: /var/log/nginx/
