To Install Apache Web Server On Oracle Linux 9.4

Introduction:

The Apache HTTP Server, commonly known as Apache, is one of the most extensively utilized web server platforms globally. It is highly regarded for its stability, flexibility, and comprehensive feature set, making it an excellent choice for a diverse array of web applications and services. Apache is compatible with multiple operating systems, including Unix, Linux, and Windows, enabling it to accommodate various deployment environments.

Step 4: Check the version of the package

[root@linuxhelp ~]# apachectl -v
Server version: Apache/2.4.57 (Oracle Linux Server)
Server built:   Aug  8 2024 00:00:00

Step 5: Start the services

[root@linuxhelp ~]# systemctl start httpd

Step 6: Enable the services

[root@linuxhelp ~]# systemctl enable httpd
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.

Step 7: Check the status of the services

[root@linuxhelp ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server

Step 8: Check the IP address

[root@linuxhelp ~]# ip a

Step 9: Check the status of firewall

[root@linuxhelp ~]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
     Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; preset: enabled)

Step 10: Enable the http port

[root@linuxhelp ~]# firewall-cmd --permanent --zone=public --add-service=http
Success

Step 11: Enable the https port

[root@linuxhelp ~]# firewall-cmd --permanent --zone=public --add-service=https
success

Step 12: Apply the changes

[root@linuxhelp ~]# firewall-cmd --reload
Success

Step 13: Access in web browser snap1

Frequently asked questions ( 5 )

Q

What is the purpose of the Apache web server?

A

Its job is to establish a connection between a server and the browsers of website visitors (Firefox, Google Chrome, Safari, etc.) while delivering files back and forth between them (client-server structure). The Apache software is also compatible with any operating system, from Windows to Unix.

Q

How many connections can the Apache server handle?

A

The Apache Web server controls concurrent connections (simultaneous requests) using the max clients directive. By default, the max client directive is set to 256.

Q

Is the Apache Web server open-source?

A

The Apache HTTP Server is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0.

Q

What is the full form of Apache?

A

APACHE II ("Acute Physiology and Chronic Health Evaluation II") is a severity-of-disease classification system, one of several ICU scoring systems.

Q

What are the disadvantages of Apache web servers?

A

Security: Security is the major concern associated with Apache web servers. As it allows an individual to do modifications in the configuration, it might cause serious security issues if not taken care of properly. Loss of permission: Having access to httpd. conf main server config file, the user shouldn't use.
