Web Server Nginx Install Di Centos 7

Introduction to Nginx

Nginx is a popular open source web server used to host websites and other applications. It is known for its high performance, stability and scalability. Nginx is written in the C programming language and is available for both Windows and Linux. It is optimized for the Linux operating system, and is especially well-suited to run on the popular CentOS distribution.

Nginx is used by many of the world’s top websites and is known for its reliability and robustness. It is easy to configure and use, and can be set up for a wide variety of web tasks including serving static pages, dynamic pages, media files, and more.

Installing Nginx on CentOS 7

Installing Nginx on CentOS 7 is relatively straightforward. The first step is to install the EPEL repository, which is where Nginx packages are available. To do this, run the following command as root on the command line:

sudo yum -y install epel-release

Once the EPEL repository is installed, you can install Nginx with the following command:

sudo yum -y install nginx

Once Nginx is installed, you can start Nginx and configure it to automatically start on boot with the following commands:

sudo systemctl start nginx.service

sudo systemctl enable nginx.service

Configuring Nginx on CentOS 7

Once Nginx is installed, the configuration files are located in the /etc/nginx directory. The main Nginx configuration file is /etc/nginx/nginx.conf. This configuration file controls how Nginx behaves, including how it serves web pages and other files.

In order to make changes to the Nginx configuration file, you will need to edit it as root. Use your favorite text editor to open the file, and make any desired changes. After making changes, verify that the configuration is correct with the following command:

sudo nginx -t

This will check the syntax of the configuration file, and if there are any errors, it will print them to the terminal. Once you are satisfied with the changes, reload Nginx with the following command to put the changes into effect:

sudo systemctl reload nginx.service

Configuring Virtual Hosts with Nginx on CentOS 7

Nginx supports creating virtual hosts, which allow you to serve multiple websites from a single server. To configure virtual hosts with Nginx on CentOS 7, you will need to create a configuration file in the /etc/nginx/conf.d directory.

The file should have a .conf extension, and it should contain the virtual host configuration. An example virtual host configuration file looks like this:

server {
  listen 80;
  server_name www.example.com;
  root /var/www/example.com;
  index index.html;
  location / {
      try files $uri $uri/ =404;

This configuration tells Nginx to serve requests for the domain www.example.com from the directory /var/www/example.com. The index directive specifies the index file to serve, and the location directive specifies what files to serve in response to requests.

Once the virtual host configuration is created, you can reload Nginx with the following command:

sudo systemctl reload nginx.service

Securing Nginx on CentOS 7

Once Nginx is installed and configured, it is important to secure it. One way to do this is to configure it to use HTTPS, which encrypts communications between the server and clients. Fortunately, setting up HTTPS for Nginx on CentOS 7 is relatively straightforward using Let’s Encrypt.

Let’s Encrypt is a service that provides free SSL certificates. To install Let’s Encrypt on CentOS 7, you will need to install the EPEL repository as described earlier, and then install the Certbot package with the following command:

sudo yum -y install certbot

Once Certbot is installed, you will need to configure it to generate a certificate for your domain. To do this, run the following command:

sudo certbot –nginx

This will interactively guide you through the process of setting up an SSL certificate for your domain. Once the certificate is installed, reload Nginx and test your website with a tool such as the Qualys SSL Test to make sure that everything is working correctly.

Troubleshooting Nginx on CentOS 7

If you are having trouble getting Nginx to work correctly on CentOS 7, the first thing to do is to check the Nginx log files. By default, Nginx logs errors and other information to the /var/log/nginx directory. You can use the tail command to view the latest entries in the log files, which can help you debug any issues you may be having.

It is also a good idea to check the Nginx configuration file for any syntax errors or other issues. Make sure you run the nginx -t command to check the configuration file before restarting or reloading Nginx.


Nginx is a powerful and popular open source web server that is well-suited for running on CentOS 7. Installing and configuring Nginx can be done quickly and easily, and once installed, configuring virtual hosts and securing the server is straightforward as well.
