Apache2 Configuration on Linux

---

Some commands to operate apache2

Restart

sudo systemctl reload apache2

Stop

sudo systemctl stop apache2

Start

sudo systemctl start apache2

Activate new conf file in sites-available

sudo a2ensite *.conf

Enable conf file

sudo service apache2 reload

Download & Installation

install apache2 server on system

sudo apt update
sudo apt install apache2

creating your Own Website

• html

/var/www/html

• setting can be edited

/etc/apache2/sites-enabled/ 000-default.conf

We can modify how Apache handles incoming requests and have multiple sites running on the same server by editing its Virtual Hosts file.

cgi enable & configuration

# enable cgi
sudo a2enmod cgi
sudo service apache2 restart
# next move
sudo mkdir /var/www/gci/
cd /var/www/gci/
nano index.html

Troubleshoot: cgi-bin configuration

Default site setting location

cd /etc/apache2/conf-available/
nano serve-cgi-bin.conf
# serve-cgi-bin.con -> default configuration let's configure custom
<IfModule mod_alias.c>
 <IfModule mod_cgi.c>
  Define ENABLE_USR_LIB_CGI_BIN
 </IfModule>

 <IfModule mod_cgid.c>
  Define ENABLE_USR_LIB_CGI_BIN
 </IfModule>

 <IfDefine ENABLE_USR_LIB_CGI_BIN>
  ScriptAlias /cgi-bin/ /var/www/cgi-bin/
  # /var/www/cgi-bin/ ---> provide your path 1. ScriptAlias 2. Directory
  <Directory "/var/www/cgi-bin/">
   AllowOverride None
   Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
   Require all granted
  </Directory>
 </IfDefine>
</IfModule>

Create symbolic link to enable it

cd /etc/apache2/sites-enabled
# if serve-cgi-bin.conf exits delete it othervise it will create error
sudo ln -s ../sites-available/serve-cgi-bin.conf

Enable CGI Module Mannualy. it won't enable by default

cd /etc/apache2/mods-enabled
sudo ln -s ../mods-available/cgi.load

Reload Apache Configuration

sudo service apache2 reload

Setting up the VirtualHost Configuration File

We start this step by going into the configuration files directory:

cd /etc/apache2/sites-available/

Since Apache came with a default VirtualHost file, let’s use that as a base. (gci.conf is used here to match our subdomain name):

sudo cp 000-default.conf gci.conf

Now edit the configuration file:

sudo nano gci.conf

We should have our email in ServerAdmin so users can reach you in case Apache experiences any error:

ServerAdmin [email protected]

We also want the DocumentRoot directive to point to the directory our site files are hosted on:

DocumentRoot /var/www/gci/

The default file doesn’t come with a ServerName directive so we’ll have to add and define it by adding this line below the last directive:

ServerName gci.example.com

This ensures people reach the right site instead of the default one when they type in gci.example.com.

Now that we’re done configuring our site, let’s save and activate it in the next step!

Activating VirtualHost file

After setting up our website, we need to activate the virtual hosts configuration file to enable it. We do that by running the following command in the configuration file directory:

sudo a2ensite gci.conf

You should see the following output

Enabling site gci. To activate the new configuration, you need to run:

service apache2 reload
root@ubuntu-server:/etc/apache2/sites-available#

To load the new site, we restart Apache by typing:

service apache2 reload

End result

Now is the moment of truth, let’s type our host name in a browser.
