Directory definitions are sometimes preceded by "Alias" or "ScriptAlias" statements. Alias maps a url path to a directory path. ScriptAlias operates in the same way, but is used to define directories that will have executable components in them. For instance, this line in a Virtual Host that handles request to "example. Following the alias, you should remember to define the directory with access privileges as discussed in the previous section.

Once you have a Virtual Host file that meets your requirements, you can use the tools included with Apache to transition them into live sites. To automatically create a symbolic link in the "sites-enabled" directory to an existing file in the "sites-available" directory, issue the following command:.

After enabling a site, issue the following command to tell Apache to re-read its configuration files, allowing the change to propagate:. There is also a companion command for disabling a Virtual Host.

It operates by removing the symbolic link from the "sites-enabled" directory:. Modules can be enabled or disabled by using the "a2enmod" and "a2dismod" commands respectively.

They work in the same way as the "site" versions of these commands. Remember to reload your configuration changes after modules have been enabled or disabled as well.

We have gone over some basic Apache configuration files. Apache is versatile and very modular, so configuration needs will be different depending on your setup. You should have a good understanding of what the main configuration files are used for and how they interact with each other.

If you need to know about specific configuration options, the provided files are well commented and Apache provides excellent documentation. Hopefully, the configuration files will not be as intimidating now, and you feel more comfortable experimenting and modifying to suit your needs.

How to Install Apache on Ubuntu and Debian If you do not already have Apache installed, you can do so now by issuing the following commands: sudo apt-get update sudo apt-get install apache2 This is all that is necessary to have a working web server.

This is the default web page for this server. The web server software is running but no content has been added, yet. These are some of the more useful locations to be familiar with: apache2.

Almost all configuration can be done from within this file, although it is recommended to use separate, designated files for simplicity. This file will configure defaults and be the central point of access for the server to read configuration details.

Be sure to check that this file is correct if you are configuring SSL. For example, it is often used to define SSL configuration and default security choices.

These will establish which content gets served for which requests. These are available configurations, not active configurations.

Usually, this directory consists of symbolic links to files defined in the "sites-available" directory. Asked 4 years, 3 months ago. Active 2 months ago. Viewed 11k times. Thanks for reading. Improve this question. Morgoth Morgoth 1 1 gold badge 3 3 silver badges 9 9 bronze badges.

Please check if apache is installed properly. Run below command to check if that installed. Here is a picture of it imgur. Sorry — Morgoth. Generally if it does not exist your create the file. To suppress the above warning message, you need to add the directive ServerName localhost at the bottom of the file or change localhost with some concrete FDQN.

Then restart Apache: sudo systemctl restart apache2. Add a comment. Active Oldest Votes. I had this happen yesterday to a friend's laptop. However, the configuration lines you need to modify are the same regardless of distribution.

The Apache web server is easy to install. With one command, you can install it and all necessary dependencies:. It contains a lot of configuration statements that don't need to be changed for a basic installation. In fact, only a few changes must be made to this file to get a basic website up and running. The file is very large so, rather than clutter this article with a lot of unnecessary stuff, I will show only those directives that you need to change. First, take a bit of time and browse through the httpd.

One of the things I like about Red Hat versions of most configuration files is the number of comments that describe the various sections and configuration directives in the files. The httpd. Use these comments to understand what the file is configuring. The first item to change is the Listen statement, which defines the IP address and port on which Apache is to listen for page requests. Right now, you just need to make this website available to the local machine, so use the localhost address.

The line should look like this when you finish:. With this directive set to the IP address of the localhost , Apache will listen only for connections from the local host. If you want the web server to listen for connections from remote hosts, you would use the host's external IP address.

That line does not need to be changed because it already points to the standard location. The line should look like this:. If you wanted to change the location where the website files are stored, this configuration item is used to do that. For example, you might want to use a different name for the www subdirectory to make the identification of the website more explicit.

That might look like this:. These are the only Apache configuration changes needed to create a simple website. For this little exercise, only one change was made to the httpd. Everything else is already configured to produce a working web server. One other change is needed, however: opening port 80 in our firewall. The entire file looks like this:. The line I added is the third from the bottom, which allows incoming traffic on port Now I reload the altered iptables configuration.

The index. Add the content Hello World.
