Any changes that you make to the configuration of the Apache HTTP server do not take effect until you restart the server:

From the Apache docs: Gracefully restarts the Apache httpd daemon. If the daemon is not running, it is started. This differs from a normal restart in that currently open connections are not aborted. Httpd is the Apache HyperText Transfer Protocol (HTTP) server program. It is designed to be run as a standalone daemon process. When used like this it will create a pool of child processes or threads to handle requests.

The main configuration file for the Apache HTTP server is /etc/httpd/conf/httpd.conf. You can modify the directives in this file to customize Apache for your environment.

The Apache HTTP Server ('httpd') was launched in 1995 and it has been the most popular web server on the Internet since April 1996. It has celebrated its 25th birthday as a project in February 2020. The Apache HTTP Server is a project of The Apache Software Foundation. Apache httpd 2.4.46 Released 2020-08-07 ¶.

Specifies a list of clients that can access content or all to serve content to any client. The Order directive determines the order in which httpd evaluates Allow and Deny directives.

Specifies a list of clients that cannot access content or all to disallow all clients. The Order directive determines the order in which httpd evaluates Allow and Deny directives.

The top level directory for Apache server content. The apache user requires read access to any files and read and execute access to the directory and any of its sub-directories. Do not place a slash at the end of the directory path.

For example:

If set to a file name, specifies the file, relative to ServerRoot, to which httpd sends error messages.

If set to syslog, specifies that httpd send errors to rsyslogd. A facility argument specifies the rsyslogd facility. The default facility is local7.

Accept incoming requests on the specified port or IP address and port combination. By default, the httpd server accepts requests on port 80 for all network interfaces. For a port number other than 80, HTTP requests to the server must include the port number.

For example:

The Apache HTTP server can load external modules (dynamic shared objects or DSOs) to extend its functionality. The module argument is the name of the DSO, and filename is the path name of the module relative to ServerRoot.

For example:

Apache Httpd Configuration Example

Specifies the order in which httpd evaluates Allow and Deny directives.

For example, permit access only to clients from the mydom.com domain:

The following directives would not permit access by any client:

Specifies the fully qualified domain name or IP address of the httpd server and an optional port on which the server listens. The FQDN must be resolvable to an IP address. If you do not specify a FQDN, the server performs a reverse-name lookup on the IP address. If you do not specify a port, the server uses the port corresponding to the incoming request.

For example:

The top of the directory hierarchy where the httpd server keeps its configuration, error, and log files. Do not place a slash at the end of the directory path.

For example:

Specifies the number of seconds that httpd waits for network operations to finish before reporting a timeout error. The default value is 60 seconds.

If set to disabled, disallows users identified by the space-separated user argument to publish content from their home directories. If no users are specified, all users are disallowed.

If set to enabled, allows users identified by the space-separated user argument to publish content from their home directories, provided that they are not specified as an argument to disabled.

directory-path is the name of a directory from which httpd publishes content. A relative path is assumed to be relative to a user’s home directory. If you specify more than one directory path, httpd tries each alternative in turn until find a web page. If directory-path is not defined, the default is ~/public_html. Do not place a slash at the end of the directory path.

For example:

The root and guest users are disabled from content publishing. Assuming that ServerName is set to www.mydom.com, browsing http://www.example.com/~alice displays alice's web page, which must be located at ~alice/www or http://www.example.com/alice (that is, in the directory alice relative to ServerRoot).

You would usually change the settings in the <IfModule mod_userdir.c> container to allow users to publish user content.

UNDERSTANDING THE SUBJECT MATTER

Apache, also called Apache http server is an open-source web server. A web server, of course, is responsible for handling web requests from various computers hitting the web. (No web server, no website).

Just as there is an Apache web server, there are also a lot of web servers out there such as Nginx, IIS, Tomcat, etc.

Httpd Apache2

Tomcat is also called Apache tomcat because it is developed by the same company that developed Apache (Apache Software Foundation)

Apache is a very popular and commonly used web server and can run on both Linux and Windows operating systems.

Just as Nginx, Apache can handle hundreds of thousands of connections trying to fetch information from the web concurrently.

With Apache, you can customize your configuration by using the “.htaccess” file.

When it comes to the Content Management System (CMS) such as WordPress, Joomla, and Drupal, they all work perfectly well on Apache, even without less or no configuration, hence why most web hosting companies use Apache and now Nginx as their web servers.

Apache application/daemon for Linux is “httpd”

The same way you start other services on Linux is also the same way Apache is started.

Httpd Apache Document Virtual Host

To start Apache, use the command

To Stop Apache, use the command,

To enable Apache, use the command,

core apache configuration file is in the path /etc/httpd/conf/httpd.conf)

Let’s see the contents in this file.

search for the line “DocumentRoot”

you can see the httpd document root (/var/www/html). It is one of the important parameters in the httpd configuration file.

Every website file will have to be on this path. The document root can be changed, especially for hardening web server security.

We will look at how to successfully change the document root of httpd when we get to the advanced configuration in another lesson.

httpd by default listens on port 80.

If you know LEMP stack, you will also know LAMP stack.

LAMP stack consists of (Linux, Apache, MySQL, and PHP). They are all web development software used to manage web applications.

How to install LAMP stack in Linux (RHEL 8 / CentOS 8)

To install Linux (RHEL 8) click here.

And Of course, in the “ACTION TIME” of this lesson, we will install Apache & configure a basic website.

To install MySQL, click on this link

To install PHP, click on this link.

Having understood what Apache is, let’s get to installing and configuring Apache for a basic website.

How To Install & Configure Apache httpd On Linux (RHEL / CentOS 7 & 8)

we will look at how to configure Apache for a basic website.

1. Install Apache web server

2. create a web file in the document root location.

3. Start the httpd service

4. If you wish, you can enable the httpd service

5. Verify the service has started

6. Test your configuration

You can use any browser or use a text-based browser such as elinks.

To use elinks in RHEL 7, install elinks by using the command,

To install elinks in RHEL 8 or CentOS 8, click on this link

7. Now that elinks has been installed, do a test.

press the enter key to open the file

You can see that the web server is properly configured.

In another tutorial, we will look at the advanced configuration of the Apache web server
