How to edit httpd.conf

[rebaths]

Hello, I need a little help editing my httpd.conf in Apache.

This is what I need to add (it's an example, I need to change the domain name and directory):

NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin webmaster@example.com
DocumentRoot /var/www/html
ServerName example.com
ServerAlias *.example.com

<Directory "/var/www/html">
AllowOverride All
</Directory>
</VirtualHost>

How do I edit this? What I have so far is:

I need to SSH into my main IP address (the IP where the WHM is) and type su root *rootpassword*

I tried that and this is what I got: -bash: /bin/su: Permisison denied

What am I doing wrong?

Thank you!

Have you added the user from which you're trying to su in the wheel group? If no, you can add it from WHM >> Manage Wheel Group Users.

Once you logged in as root, You can find the apache conf in /usr/local/apache/conf/httpd.conf.

If you need any assistance on this, please open a ticket with the root password.

Which control panel you have? The path of httpd.conf may differ according to control panel. In cPanel, you will find it in /usr/local/apache/conf and most of the other control panels, you will find it in /etc/httpd/conf/ directory.

In cPanel, changes made to httpd.conf will not be preserved as httpd.conf is no longer being used as data store. It is rebuilt based on the information stored at /var/cpanel/userdata.

Thanks.

I added my user to the wheel group.

I am in fact using cPanel, so what you are saying is that any changes I make to httpd.conf won't have any affect, and that I have to make the changes to /var/cpanel/userdata instead?

Exactly. You will need to make changes in respective /var/cpanel/userdata/USER/DOMAIN.COM file and then rebuild httpd.conf as:

/usr/local/cpanel/bin/build_apache_conf

If it doesn't show any error and shows httpd.conf built OK message then restart Apache afterwards:

/scripts/restartsrv httpd
