Nginx Config Test Centos 7

What is Nginx?

Nginx is an open-source, high-performance web server that can be used to host static files, and also to serve dynamic requests such as PHP scripts. It is often used as a reverse proxy, meaning that it will serve requests from external sources to internal applications. Nginx also provides a vast array of configuration options for customizing the behavior of the server, including options for limiting concurrent requests, setting redirects, and more.

The popularity of the Nginx server has grown steadily since its initial release in 2004, and it is now one of the most popular open-source web servers. It is used in a wide variety of scenarios, from large-scale web applications, to simpler tasks such as serving static files or setting up a reverse proxy. With a powerful configuration language and a lightweight footprint, Nginx is a highly versatile web server that continues to remain at the forefront of modern web technology.

Setting up Nginx on Centos 7

Setting up Nginx on Centos 7 is relatively simple. There are a few steps that must be taken before Nginx can be installed:

  • On Centos 7, the EPEL repository must first be enabled. This can be done by running the following command:yum install epel-release
  • Next, the Nginx package must be downloaded and installed. This can be done by running the following command:yum install nginx
  • Once the Nginx package has been installed, it must be started. This can be done by running the following command:systemctl start nginx
  • Finally, the Nginx service must be enabled to start automatically at boot. This can be done by running the following command:systemctl enable nginx

At this point, Nginx should be installed and running on your system. To verify this, you can use the following command:systemctl status nginx.

Testing the Nginx Installation

Once Nginx has been installed, we can test to make sure that it is running correctly. To do this, we need to make sure that it is responding to requests correctly. We can use the curl command to do this.

The curl command allows us to make HTTP requests to a web server. To test the Nginx installation, we can use the following command:curl -I http://localhost. This will make an HTTP request to the Nginx server and return the HTTP headers that were sent back. If the Nginx installation is working correctly, you should see something like this:

HTTP/1.1 200 OK
Server: nginx/1.10.1
Date: Mon, 17 Dec 2017 16:32:15 GMT
Content-Type: text/html; charset=UTF-8

The above output shows that the Nginx server is running correctly and that it is sending the correct HTTP headers.

Configuring Nginx on Centos 7

Once the Nginx server is installed and running, it is time to look at configuring it. Nginx is highly configurable, and a vast array of settings can be tweaked in order to customize how it works. The best way to get started is to create a new configuration file for your domain.

To do this, you will need to create a new configuration file for your domain in the /etc/nginx/sites-enabled/ directory. This file should contain all of the settings that you need to customize the behavior of the Nginx server. The following example shows a basic configuration file:

server {
server_name www.example.com;
listen 80;
root /var/www/example.com;
index index.html index.htm;

location / {
try_files $uri $uri/ /index.html;
}
}

This example configuration will serve requests for the domain www.example.com and serve up files from the /var/www/example.com directory. This configuration can be tweaked to serve different content for different domains or different addresses.

Testing the Nginx Configuration

Once you have created the configuration file for your domain, it is time to test it. This can be done by using the nginx -t command. This command will check the configuration file for any syntactical errors and report them if any are found.

If the configuration file is syntactically correct, then the command should return an OK message. If there is an error, it should provide the line number that contains the error. Once the configuration is syntax-checked, you can restart the Nginx service to make sure that the new settings are applied. This can be done by running the following command:systemctl restart nginx.

Conclusion

In this article, we have looked at how to set up and configure the Nginx server on Centos 7. Setting up Nginx is relatively simple, and the server can be configured to serve different content for different domains or addresses. We have also looked at how to test the Nginx configuration, to make sure that it is working correctly.
