Apache Apache Hypertext Transfer Protocol Server.
The service version (shown in native reported format ) is:
# /usr/sbin/apache2 -V Server version: Apache/2.2.14 (Ubuntu) Server built: Apr 13 2010 20:22:19 Server's Module Magic Number: 20051115:23 Server loaded: APR 1.3.8, APR-Util 1.3.9 Compiled using: APR 1.3.8, APR-Util 1.3.9 Architecture: 64-bit Server MPM: Worker threaded: yes (fixed thread count) forked: yes (variable process count)
Apache server is configured to start at the VM boot time.
If you get this error:
then use a text editor such as vim to create a new file
# vim /etc/apache2/conf.d/fqdn
to the file and save. This can all be done in a single command with the following:
echo "ServerName localhost" | sudo tee /etc/apache2/conf.d/fqdn
Apache2 has the concept of sites, which are separate configuration files that Apache2 will read. These are available in /etc/apache2/sites-available. By default, there is one site available called default this is what you will see when you browse to http://localhost or http://127.0.0.1. You can have many different site configurations available, and activate only those that you need.
As an example, we want the default site to be /home/user/public_html/. To do this, we must create a new site and then enable it in Apache2.
To create a new site:
# sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/mysite
# vim /etc/apache2/sites-available/mysite
Now, we must deactivate the old site, and activate our new one. Ubuntu provides two small utilities that take care of this: a2ensite (apache2enable site) and a2dissite (apache2disable site).
# sudo a2dissite default && sudo a2ensite mysite
Finally, we restart Apache2:
sudo /etc/init.d/apache2 restart
If you have not created /home/user/public_html/, you will receive an warning message
To test the new site, create a file in /home/user/public_html/:
# echo 'Hello! It is working!' > /home/user/public_html/index.html
Finally, browse to http://localhost/
For more server settings, please check configuration files from /etc/apache2/conf.d/ and /etc/apache2/sites-enabled/ directories.
