CentOS 8 Linux is here with running OS Stream based, let’s see how we can turn them into a web server by installing the open source Apache web server software.
The Apache web server is free and open source and powers a large majority of Linux web hosting services. It can be installed on almost any Linux, be it CentOS 8, 7 or 6; RHEL, Ubuntu, Debian etc. It is created by the Apache foundation and supports HTTPS and HTTP protocols. On the CentOS or RHEL system or their forks, it is recognized as an httpd service.
Steps to install Apache on CentOS 8 Linux
The steps here are performed on CentOS 8, however, they are applicable and the same for Redhat 8 and CentOS stream Linux.
Open the command terminal and log in as root
To install Apache (httpd) on CentOS 8, we need root access without this server system allowing us to install anything. In addition, if you are using the graphical user interface, you can access the control terminal from the Activities menu given in the taskbar at the top right.
Update system
Run the following command to update all installed packages to their most recent and stable version.
dnf update
Where
yum update
To note: The latest CentOS is based on RHEL 8 and now supports dnf command, however, yum can still be used as usual. However, here we show both.
Command to install Apache (httpd) on CentOS 8 or Stream
So here is the one line command to download and install the Apache web server packages. What is given below with the two Yum and dnf.
yum install httpd
Where
dnf install httpd
The output of the above command:
Package Arch Version Repository Size ============================================================================================================== Installing: httpd x86_64 2.4.37-11.module_el8.0.0+172+85fc1f40 AppStream 1.7 M Installing dependencies: apr x86_64 1.6.3-9.el8 AppStream 125 k apr-util x86_64 1.6.1-6.el8 AppStream 105 k centos-logos-httpd noarch 80.5-2.el8 AppStream 24 k httpd-filesystem noarch 2.4.37-11.module_el8.0.0+172+85fc1f40 AppStream 34 k httpd-tools x86_64 2.4.37-11.module_el8.0.0+172+85fc1f40 AppStream 102 k mod_http2 x86_64 1.11.3-2.module_el8.0.0+10+abf51267 AppStream 156 k mailcap noarch 2.1.48-3.el8 BaseOS 39 k Installing weak dependencies: apr-util-bdb x86_64 1.6.1-6.el8 AppStream 25 k apr-util-openssl x86_64 1.6.1-6.el8 AppStream 27 k Transaction Summary ============================================================================================================== Install 10 Packages Total download size: 2.3 M Installed size: 6.1 M Is this ok [y/N]:
When it asks for permission to install Apache, enter Yes and let it download and install this open source web server.
Activate the Apache web server
After the successful installation, we will enable the Apache web server service so that it can be started automatically even after the system starts. The command for this is.
systemctl enable httpd
Start the httpd service on CentOS 8
We will now start the Apache service so that we can access and install our website on it.
systemctl start httpd
The output of the above commands:
[[email protected] ~]# systemctl enable httpd Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service. [[email protected] ~]# systemctl start httpd [[email protected] ~]#
Open HTTP firewall port 80
If you access the web server on the same local machine where you installed it, there will be no problem. However, the moment you want to access it using another remote computer or even using one that is on the same network as the web server, the CentOS 8 firewall will not allow you to do so. . So we have to open the Port number 80 in the firewall so that users can connect to our Apache web server.
To do this, use the command below.
Command to expose http port 80 to the public.
firewall-cmd --zone=public --permanent --add-service=http
Now reload the firewall service to apply the changes.
firewall-cmd --reload
Similarly, you can also open https port 443 for your Apache web server on CentOS 8.
Access the web server to test
Now, finally, it’s time to see if our installed httpd server is working or not. To do this, simply open your browser and type in the CentOS 8 IP address of the installed web server. For example our system Ip is 192.168.43.85, so the url will be like this http://192.168.43.85:80
If you are on the same local system, you can also use localhost: http: // localhost: 80 Where http: //127.0.01: 80.
The result will be like this:
Install your web page or site on the web server
To access the web directory where you can put your web files on the server, follow the command below.
cd /var/www/html/
Add your files to the HTML directory and after that you can access them locally or remotely on your web server.
