RHEL7: Configure an Apache virtual host.

Share this link

Note: This is an RHCE 7 exam objective.

Prerequisites

First, follow the instructions to install an Apache web server.

Configuration Procedure

Let’s assume your website is called dummy-host.example.com.

Create the /var/www/html/dummy-host.example.com directory:

# cd /var/www/html
# mkdir dummy-host.example.com

Create an index.html file and assign the correct SELinux context:

# echo "This is a test." > dummy-host.example.com/index.html
# restorecon -R dummy-host.example.com

Create the /etc/httpd/conf.d/vhosts.conf file and paste the following lines:

<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /var/www/html/dummy-host.example.com
ServerName dummy-host.example.com
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>

Optionaly, rename the /etc/httpd/conf.d/ssl.conf file, otherwise you get an additional non-working https virtual host displayed in the configuration.

# cd /etc/httpd/conf.d; mv ssl.conf ssl.conf2

Check the validity of the configuration:

# apachectl configtest
Syntax OK

Note: You can also type: # httpd -t

Restart the httpd service:

# apachectl restart

Note1: You can also type: # systemctl restart httpd
Note2: For minor configuration changes, it is also possible to restart the Apache daemon without losing the current connections: # apachectl graceful

Check the virtual host(s) configuration:

# httpd -D DUMP_VHOSTS
VirtualHost configuration:
*:80                   is a NameVirtualHost
         default server dummy-host.example.com (/etc/httpd/conf.d/vhosts.conf:1)
         port 80 namevhost dummy-host.example.com (/etc/httpd/conf.d/vhosts.conf:1)
         port 80 namevhost dummy-host.example.com (/etc/httpd/conf.d/vhosts.conf:1)

Testing Time

Check the configuration:

# yum install -y elinks
# elinks http://dummy-host.example.com

Thank you for your awesome RHCE notes, I really appreciate your time and effort to help others. Just in case few people might wonder, I like to add few notes here: – Time is gold during the exam, it seems to me, the fastest and shortest command that you can run to install everything you need for httpd\apache questions is : # yum groupinstall -y “Web server” – Just to make sure you don’t get any read permission issues, perform below command when you are done creating directories and files under /var/www – # chmod -R 755 /var/www – Don’t… Read more »

your vitual host config for the second website should be enclosed inside

and one should obviously open port 8080 on the firewall

As you do not use one of the standard ports

I was wondering, can we install httpd-manual and use it during exam?

For people who do not want to remember the syntax (it is worth to know also to other applications):
1. Let’s find mem and doc files:
rpm -qd httpd
2. Let’s check the file from above list:
/usr/share/doc/httpd-2.4.6/httpd-vhosts.conf
3. Copy, paste and modify 🙂

Hello All, is it normal to see 2 records for each vhost with the following command?
