# mkdir username
# cd username
# cd example

5. If the directory “example” is not present, create it

6. Check for the file cp_jkmount.conf here, if it is not present, create it with the following contents
——————————————–

How to ignore some files/folders from awstats reports in cPanel

Awstats will consider as a page hit any entry from the log it processes. By default some file extensions (for regular image types and css/js) are excluded from what awstats will consider as a page:

NotPageList=”css js class gif jpg jpeg png bmp ico”(this is the default). All other file types will be counted as pages. Now, if we want to completely ignore some files, or even all the content of one folder from the awstats processing we can use the SkipFiles parameter. We might want to do this to ignore some frames, hidden pages, ajax calls, etc.

The SkipFiles parameter is by default empty, and in order to use it we have to add the appropriate config in our awstats.conf file.  For example to ignore a file called somefile.php we will add “/somefile.php“:
SkipFiles=”/somefile.php”
while if we want to ignore all the pages in a folder called somefolder we will have to use a regex value like: “REGEX[^\/somefolder]“
We can add several rules separated by spaces:
SkipFiles=”/somefile.php REGEX[^\/somefolder]”

Note: this will be effective only for new updates; meaning existing data will not be affected by this (if really needed you will have to regenerate your stats to get rid of those pages in old stats).

How to Pointing a sub-domain to folder outside public_html in cPanel

When you create a sub-domain, cPanel points it to the corresponding folder under public_html by default. How to point it to a folder outside the public_html, This cannot be done via cPanel/WHM but can be achieved if you have ‘root’ SSH access to the server.

1. Open the apache configuration file — /etc/httpd/conf/httpd.conf
2. Search for the virtual host entry for your sub-domain.
3. Edit the document root of your sub-domain to match the desired location.
4. Save and Exit. Restart apache.

Note: cPanel rebuilds httpd.conf from userdata files and its overwritten on every cPanel update, on every account creation, subdomain addition, or any such activity related to apache & any manual changes you make will be overwritten. To make permanent changes to a subdomain’s root folder :

1. Edit the file /var/cpanel/userdata/username/subdomain.domain.com file, change the path and save it.
2. Run /scripts/rebuildhttpdconf
3. Restart apache.

How to disable strict zone checking in bind in cPanel

Recent versions of Bind distributed by RedHat and CentOS enable strict zone checking at startup time. This setting can potentially cause problems for Bind users with a large number of zone files or syntax errors in individual zone files.

As a result, users may experience an inability to restart Bind after a shutdown. cPanel has, immediately, produced and distributed an autofixer for this condition. This repair will run automatically on all systems with updates enabled. However, cPanel checks only occur at specific times and depending upon update schedules, users experiencing issues restarting Bind may benefit from manually executing the code to disable strict zone checking. If you are facing this problem,
you may safely execute the autofixer by running the following command:

# /scripts/autorepairbind_disable_checkzone

Disabled features still visible in cPanel

Issue :

Certain features were disabled in WHM. However, they are still visible in cPanel. So, clients can still click on it and then they see that the feature has been disabled. This sends the wrong message to the client. If the option isn’t visible, it cannot be misinterpreted.

Solution :

The features were disabled in the following way :
WHM –> Feature Manager –> Select “Default” –> Edit –> Unchecked the feature from list –> Save.

You should edit the “Disabled” list instead of the “Default” list.

If you remove the feature from “Default”, the feature will only be removed for those users who don’t explicitly have another feature list assigned to their hosting package.

When you disable the feature in the “Disabled” feature list, it is removed from the system entirely for all users regardless of the hosting package or feature list assigned to that package and hides the option in cPanel.
