CentOS Stream 8 Web Server Configuration

To build a web server on a CentOS Stream 8 system, you need to install and configure web server software (such as Apache or Nginx) and make necessary security settings. The following steps provide a basic configuration process:

Web server software installation

Install Apache with the following command:

 sudo dnf install httpd -y

The installation of Nginx requires reference to its official documentation for compilation and installation, such as installing Nginx version 1.22.

Firewall configuration

The default firewall of CentOS 8 prevents external access to the web server. HTTP and HTTPS ports are required:

 sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

Virtual Host Creation

To run multiple websites on one server, you need to create a virtual host. For example, create a virtual host named example.com :

 sudo nano /etc/httpd/conf.d/example.com.conf

Add the following to the file:

<virtualhost>
    ServerAdmin admin@example.com
    DocumentRoot /var/www/html/example.com
    ServerName example.com
    ServerAlias ​​www.example.com
    ErrorLog /var/log/httpd/example.com-error.log
    CustomLog /var/log/httpd/example.com-access.log combined
</virtualhost>

SSL/TLS configuration

To ensure data security, it is recommended to configure SSL/TLS. You can use free services such as Let's Encrypt to obtain an SSL certificate. Install Certbot and get the certificate:

 sudo yum install certbot python2-certbot-apache -y
sudo certbot --apache

Set up the power-on self-start

Make sure Apache starts automatically after the system restarts:

 sudo systemctl enable httpd

Server monitoring and maintenance

Regularly checking Apache's access logs and error logs and automatically updates using the yum-cron tool is the key to keeping the server running stably.

Note: The above steps are only basic guides, and the actual configuration may vary depending on the specific requirements. Please adjust the relevant parameters according to the actual situation.
