Remove Apache And Install Nginx
What is Apache and Nginx?
Apache and Nginx are both popular web servers used to serve web pages and content to users on the web. Apache, originally released in 1995, is the most popular web server. It is open source and supports a variety of protocols, such as HTTP, HTTPS, and FTP. Nginx, on the other hand, is a relatively newer web server that was released in 2004. It is open-source and also supports multiple protocols. It is renowned for its high performance and scalability.
Why Remove Apache and Install Nginx?
There are several reasons why you might want to remove Apache and install Nginx. Firstly, Nginx is generally more efficient when it comes to resource utilization and can handle a large number of concurrent requests without performance issues. Additionally, Nginx is great for serving static content due to its low memory requirements and is suitable for web servers with high traffic. Also, Nginx is simpler to configure than Apache and has a more powerful feature set.
How to Remove Apache and Install Nginx on CentOS?

How to Configure Nginx?
Once Nginx is installed, it is important to configure it correctly in order to ensure the best performance. There are a few steps which you should take to configure Nginx properly. Firstly, you should use a text editor to make changes to the Nginx configuration file. You can access it by running the following command:
- sudo vi /etc/nginx/nginx.conf
By making changes to this file, you can set up the base configuration for your server, such as the IP address, port, and domain name. You may also need to add additional configuration directives to optimize Nginx for your specific needs.
How to Secure Nginx?
It is important to secure Nginx in order to prevent any malicious attacks. The following are some steps which you can take to ensure the security of your Nginx server:
- Ensure that your server is up to date with the latest security patches.
- Install an anti-virus/malware and anti-spam application.
- Set up a firewall to filter incoming and outgoing traffic.
- Install a web application firewall to protect against application-level attacks.
- Disable unused components and modules to reduce attack surface.
- Create secure password policies and limit access to sensitive files.
- Set up SSL/TLS encryption for incoming and outgoing traffic.
- Use IP address whitelisting to grant access to certain users only.
