1. Linux Nginx web server vs apache web server

Web servers installed on Linux are divided into Nginx web servers and Apache web servers, and have the following differences.

Original Korean article: Install Nginx web server (Centos 8)

• Apache is an open source HTTP server, while Nginx is an open source, high-performance asynchronous web server and reverse proxy server.
• While the development and evolution of Apache HTTP Server is managed and maintained by a global user community (Apache Software Foundation), Nginx is maintained and maintained by the company of the same name, founded in 2011.
• While Apache provides various multiprocessing modules to handle client requests and web traffic, Nginx is designed to handle multiple client requests simultaneously with minimal hardware resources.
• In Apache, a single thread is associated with one connection, but in Nginx, a single thread can handle multiple connections. This process consumes less memory and improves performance.
• While Apache HTTP Server has a non-scalable, multi-threaded architecture, Nginx follows an asynchronous event-based approach to handling multiple client requests.
• The Apache server serves static content using traditional methods and handles dynamic content natively within the web server itself. Nginx, on the other hand, cannot handle dynamic content internally and relies on external processes to do so.

In other words, Apache has a relative advantage in terms of security and stability, and nginx has a relative advantage in terms of efficiency and speed. Activate and install Centos 8 RHEL & REMI Repository.

2. Install nginx web server

1) Update

sudo dnf update

2) Search nginx and check version

sudo dnf list install nginx

3) Install nginx

sudo dnf install -y nginx.x86_64

3) Add http(80) port

sudo firewall-cmd --permanent --zone=public --add-port=80/tcp

4) Update firewall

sudo firewall-cmd --reload

If you check with the following command, you can see that the 80/tcp item in ports has been added.

sudo firewall-cmd --state

If you want to delete a port, you can use the following command to delete an open port.

firewall-cmd --permanent --zone=public --remove-port=80/tcp

5) Check web access

Enter the IP address in a web browser and the following screen will appear.

If an error occurs in the web browser, check the status of nginx to see if it is operating normally. Next, check whether the firewall is working and port 80 is open.
