Nginx Centos 7.6 Virtual Host
Introduction to Nginx Virtual Hosts
Virtual Hosts, also called Virtual Servers, are a very important function of web hosting. They allow multiple websites to run on a single server, and are a popular way for web hosting companies to manage their resources. Virtual Hosts are also often used to give each website, or group of websites, their own space on the server, and to provide access to multiple websites from a single IP address.
Nginx is a powerful and popular web server that has been gaining popularity in recent years due to its scalability and performance. In this article, we will take a look at how to configure Nginx virtual hosting on a CentOS 7.6 server. We will discuss the basics of setting up a virtual host, and will go over the different types of virtual hosts available.
Creating a Nginx Virtual Host
To create a virtual host in Nginx, we will need to configure the Nginx configuration file. The configuration file is located in the /etc/nginx/nginx.conf directory. In this file, we will define the server blocks, or virtual hosts, for each website. We will also define the server name and root directory for each server block.
The first step is to create a server block for each website. This is done by adding the following code to the Nginx configuration file:
server_name domain.com www.domain.com;
This code will define the domain name, www.domain.com, as the server name, and the directory /var/www/domain/public_html as the root directory for the website. Replace the domain name and directory with the appropriate values for your website. This code will need to be repeated for each website you wish to create.
Once the server blocks are configured, we can then configure the Nginx server to listen on port 80. To do this, we will add the following code to the Nginx configuration file:
This will allow Nginx to listen for requests on port 80. This code needs to be added after all of the server blocks that were created earlier.
Configuring Nginx Domain Aliases
In addition to creating server blocks for each website, we can also use Nginx to configure domain aliases. Domain aliases are used to redirect requests from one domain name to another. For example, if you have two websites, domain1.com and domain2.com, you can use Nginx to redirect requests from domain1.com to domain2.com. This is done by adding the following code to the Nginx configuration file:
return 301 http://domain2.com$request_uri;
This code will redirect any requests for domain1.com to domain2.com. This is useful if you have multiple websites running on the same server and want to redirect requests from one domain name to another. You can add as many domain aliases as you need. Just make sure they are properly configured in the Nginx configuration file.
Securing Your Nginx Virtual Hosts
There are a few steps you can take to ensure that your Nginx virtual host configuration is secure. The first step is to enable the Nginx security module. This module will help protect your websites from potential security vulnerabilities. This is done by adding the following code to the Nginx configuration file:
Once the security module is enabled, you can then configure the security parameters for your virtual hosts. You can set limits on the number of requests per second and the size of requests that can be sent to your website. You can also configure which IP addresses are allowed to access your website and which IP addresses are blocked. These are just a few of the security measures you can put in place.
Virtual Host Troubleshooting
If you encounter any issues with your virtual hosts, the first step is to make sure that the config files are properly configured. Check to make sure that there are no typos or syntax errors in the files. If there are no errors, then try restarting the Nginx server. This should fix any errors that may have occurred during the configuration process.
If you are still having issues after restarting the server, then try checking the log files for any errors or warnings. The log files can be accessed in the /var/log/nginx directory. This should give you a better idea of what is going wrong and will help you troubleshoot the issue.
