In the context of virtual hosts, the ServerName specifies what hostname must appear in the request's Host: header to match this virtual host. For the default virtual host this file this value is not decisive as it is used as a last resort host regardless.
However, you must set it for any further virtual host explicitly. ServerName www. It is also possible to configure the loglevel for particular modules, e. For example the following line enables the CGI configuration for this host only after it has been globally disabled with "a2disconf". Improve this question.

Run the following commands: sudo a2dissite default sudo a2ensite default sudo systemctl restart apache2 This will disable the "Default" site, enable the "Default" site, and then the restart of Apache will refresh the configuration and should then use the updated docroot accordingly.

Although there are many viable web servers that will serve your content, it is helpful to understand how Apache works because of its ubiquity. In this article, we will examine some general configuration files and options that can be controlled within them.
If you do not already have Apache installed, you can do so now by issuing the following commands:. This is all that is necessary to have a working web server. There are a number of plain text files and some sub-directories in this directory. These are some of the more useful locations to be familiar with:. As you can see, Apache configuration does not take place in a single monolithic file, but instead happens through a modular design where new files can be added and modified as needed.
This file is divided into three main sections: configuration for the global Apache server process, configuration for the default server, and configuration of Virtual Hosts. In Ubuntu and Debian, the majority of the file is for global definitions, and the configuration of the default server and virtual hosts is handled at the end, by using the "Include The "Include" directive allows Apache to read other configuration files into the current file at the location that the statement appears.
The result is that Apache dynamically generates an overarching configuration file on startup. If you scroll to the bottom of the file, there are a number of different "Include" statements. These load module definitions, the ports. By default, this parameter is set to "", which means that the server has a maximum of seconds to fulfill each request. This is probably too high for most set ups and can safely be dropped to something between 30 and 60 seconds.
This option, if set to "On", will allow each connection to remain open to handle multiple requests from the same client. If this is set to "Off", each request will have to establish a new connection, which can result in significant overhead depending on your setup and traffic situation. This controls how many separate request each connection will handle before dying.
Keeping this number high will allow Apache to serve content to each client more effectively. Setting this value to 0 will allow Apache to serve an unlimited amount of request for each connection. This setting specifies how long to wait for the next request after finishing the last one.
If the timeout threshold is reached, then the connection will die. This just means that the next time content is requested, the server will establish a new connection to handle the request for the content that make up the page the client is visiting. You can cross-reference which section your Apache installation was compiled with by exiting into the terminal and typing:.
As you can see, in this server, "prefork. Your installation may have multiple to choose from, but only one can be selected. The default Virtual Host declaration can be found in a file called "default" in the "sites-available" directory. We can learn about the general format of a Virtual Host file by examining this file.
Open the file with the following command:. The default Virtual Host is configured to handle any request on port 80, the standard http port. This does not mean that it will necessarily handle each request to the server on this port however. Apache uses the most specific Virtual Host definition that matches the request. This means that if there was a more specific definition, it could supersede this definition.
By doing this, the server checks its hosts file before consulting with the DNS server. Assuming our domain name is www. If nothing is specified, Apache listens to all addresses and ports on the machine.
The default configuration sets the server to listen to port 80, the default port for HTTP communication. If you only specify an IP address, the server will respond to requests coming to all ports of that address also called an interface.
If only a port number is specified, then Apache responds to requests on the specified port arriving at all interfaces on the machine. If your server installation has separate configuration files, you should be able to find or set this directive in the ports.
Alternatively, if you want Apache to listen to ports 80 and on all interfaces regardless of the IP address, you can enter the following:. Doing so makes the server more secure and less vulnerable to attacks. Ideally, the user and group you set should not be able to login to the server ie: have no login credentials and no login shell; they will just be used for handling web client requests.
The example above uses anyUserName as our web user and group; just use a name not reserved for other processes. Next, you need to modify your config file to use the new Apache user and group. If yours says:. Then you need to find where these variables are defined and change their values. Usually, the above directive is preceded by a comment letting you know exactly where to set the new values.
Otherwise, you will just insert the new user and group name in place of the old. So your final config lines could look like this:. Any Apache directives using a relative path will, by default, append to the root path specified in ServerRoot. When you first install your server, the configuration and log files are placed in the ServerRoot.
You can change its value to a new directory, but make sure to copy the configuration files to the new location. Also, make sure you do not to add a trailing slash to the path when you modify the value. When an error occurs, Apache logs the error to a log file. The location of the error log is determined by the value specified using the ErrorLog directive.
