How to install Apache web server on CentOS Linux
How to install Apache web server on CentOS Linux
After updating the system, use yum or dnf to install httpd; 2. Start and enable the Apache service; 3. Configure the firewall to allow HTTP/HTTPS; 4. Access the server IP with the browser to view the default page; 5. The website file is located in /var/www/html, and you can edit the custom content of index.html.
To install the Apache web server on CentOS Linux, follow these straightforward steps. This guide works for CentOS 7, 8, and Stream versions. Apache (also known as httpd ) is reliable, widely used, and easy to set up for hosting websites.
1. Update Your System
Before installing any new software, make sure your system packages are up to date. Open a terminal and run:
sudo yum update -y
If you're on CentOS 8 or Stream, you might use dnf instead:
sudo dnf update -y
2. Install Apache (httpd)
Use the package manager to install the Apache web server:
sudo yum install httpd -y
On CentOS 8/Stream:
sudo dnf install httpd -y
3. Start and Enable Apache Service
After installation, start the Apache service and configure it to launch at boot:
sudo systemctl start httpd sudo systemctl enable httpd
You can check its status with:
sudo systemctl status httpd
If active (running), Apache is now serving pages.
4. Configure Firewall Access
If you have a firewall enabled (like firewalld ), allow HTTP (port 80) and optionally HTTPS (port 443):
sudo firewall-cmd --permanent --add-service=http sudo firewall-cmd --permanent --add-service=https sudo firewall-cmd --reload
5. Test the Web Server
Open a web browser and navigate to your server's IP address:
http://your_server_ip
You should see the default Apache test page. The default document root is /var/www/html .
6. Manage Website Content (Optional)
To host your own site, place HTML files in the web directory:
sudo nano /var/www/html/index.html
Edit or replace the file with your content. Restart Apache if needed:
sudo systemctl restart httpd
Basically, that's it. Apache is now installed and running on your CentOS system. You can further customize configurations in /etc/httpd/conf/httpd.conf or add virtual hosts as needed.

How to manage software packages using Dnf and Rpm in Linux?
Mar 07, 2026 am 01:50 AM
dnfinstall prompts packagenotfound because it queries the enabled warehouse rather than the local installation status; rpm-q queries the local RPM database, and the scopes of the two are different.
How to monitor system performance and resources in Linux? (Top & Htop)
Mar 06, 2026 am 01:04 AM
The total top CPU usage is not 100% because it is calculated based on a single core, and the maximum is 800% for an 8-core system; the htop terminal size error needs to be fixed with eval$(resize); the real memory pressure is available rather than used; top command line truncation can be solved with the -c parameter.
How to setup file sharing using Samba on Linux? (SMB Protocol)
Mar 13, 2026 am 12:33 AM
The main reason why Windows cannot see the Samba share is that the firewall blocks UDP137–139/TCP445 or NetBIOS name resolution fails; it is necessary to confirm that the workgroup is consistent, the interfaces are configured correctly, the file permissions match forceuser/forcegroup, and set doscharset=UTF-8 to solve Chinese garbled characters.
How to extend a Logical Volume (LVM) in Linux without downtime?
Mar 13, 2026 am 12:53 AM
Logical volumes and file systems can be expanded online. You need to expand the LV first and then the file system. It is recommended to use lvextend-r for automatic synchronization adjustment, but you must ensure that the LVM and file system tool versions are compatible.
How to check open ports and listening services in Linux? (Netstat & SS)
Mar 10, 2026 am 01:08 AM
Netstat displays fewer LISTEN ports than ss because it does not display process information by default that non-root users do not have access to; ss can read all listening sockets by default without process names, and sudonetstat-tulpn is required to display them completely.
How to set up SSH key authentication on Linux? (Passwordless Login)
Mar 11, 2026 am 12:46 AM
It is recommended to use ssh-keygen-ted25519 to generate a key pair, because it is faster, more secure, and has a shorter key than the default RSA; it is necessary to strictly set the ~/.ssh directory permissions to 700 and authorized_keys to 600, and use ssh-v to confirm whether the client is Offering public key and whether the server rejects it.
How to format disk partitions using the command line in Linux?
Mar 15, 2026 am 12:01 AM
When fdisk is stuck at the Command prompt, it is normally waiting for input. Enter q to exit safely; you must umount before mkfs, otherwise it may fail silently; partedmkpart does not support the specified file system type, and mkfs needs to be executed separately.
How to configure a static IP address on Linux? (Netplan & NetworkManager)
Mar 14, 2026 am 12:02 AM
Netplan reports "InvalidYAML" when configuring a static IP due to indentation errors, missing spaces after colons, or mixed tabs; gateway4 has been deprecated and routes to:default must be used instead; NetworkManager needs to be modified before down/up takes effect; the renderer field is used to determine the backend during coexistence; incorrect DNS configuration will cause ping to succeed but curl to fail.
