Gunjan — Sat, 04 Feb 2012 17:18:43 +0000

After upgrading the cPanel version, the following error is occur when we are browsing the phpMyAdmin.

Warning: Invalid argument supplied for foreach() in /usr/local/cpanel/base/3rdparty/phpMyAdmin/tbl_replace.php on line 52

Warning: Invalid argument supplied for foreach() in /usr/local/cpanel/base/3rdparty/phpMyAdmin/tbl_replace.php on line 155

Warning: Cannot modify header information – headers already sent by (output started at /usr/local/cpanel/base/3rdparty/phpMyAdmin/tbl_replace.php:52) in /usr/local/cpanel/base/3rdparty/phpMyAdmin/libraries/common.lib.php on line 1154

To resolve the above error, we can simply enable the output_buffering in the following file.

/usr/local/cpanel/3rdparty/lib/php.ini

Change the “output_buffering” from Off to On.

Gunjan — Sun, 22 Jan 2012 09:24:01 +0000

After enabling the suphp on the server,many time 500 Internal Server Error occur due to the incorrect permission,ownership and incorrect php module defined in the .htaccess file and we can’t make the changes manually therefore we can use the following script to make the all the changes server.

cPanel log to check when hosting created and deleted

Gunjan — Wed, 11 Jan 2012 13:28:55 +0000

In the recent days, we all are facing the hacking issue at that time, we always see problem like account termination from the serve at that time, we can use the following log file to investigate the issue as its providing when hosting account was created, owner changed or account deleted from the server.

For example we are checking logs for the domain test123.com and as per the following logs the hosting account for domain test123.com is created by using the root owner on dated Wed Jan 11 08:19:40 2012 and onwership is under root

root@linux7802 [~]# cat /var/cpanel/accounting.log | grep test123.com
Wed Jan 11 08:19:40 2012:CREATE:root:root:test123.com:115.124.103.126:admin111

Now we have changed the ownership for the domain test123.com hosting account to linux780 reseller ownership therefore check the following logs

root@linux7802 [~]# cat /var/cpanel/accounting.log | grep test123.com
Wed Jan 11 08:22:51 2012:CHANGEOWNER:root:root:test123.com:admin111:root:linux780

Now we have terminated the hosting account for the domain test123.com by using the root user and its also recorded in the accounting.log

root@linux7802 [~]# cat /var/cpanel/accounting.log | grep test123.com
Wed Jan 11 08:25:14 2012:REMOVE:root:root:test123.com:admin111

So we can similarly check the logs for all the domains when they have created/modified or removed from the server and its always to better to maintain the accounting.log for future reference.

Gunjan — Sun, 08 Jan 2012 16:28:00 +0000

While browsing the file manager from the cPanel the 404 not found error message is occur.

Not Found

The server was not able to find the document (./frontend/x3/index.html) you requested.
Please check the url and try again. You might also want to report this
error to your web hosting provider.

whostmgrd/11.25

As per above error message x3 theme is causing the problem therefore simply move the x3 theme and resinstall it by running the upcp, you can rename the theme under which you are facing the problem.

linux@server[~]#cd /usr/local/cpanel/base/frontend

linux@server[~]#mv -v x3 x3-corrupt

linux@server[~]#/scripts/upcp –force

Now browse the file manager, it will work properly.

Gunjan — Tue, 13 Dec 2011 10:22:19 +0000

To update the webalizer for the single domain refer the following steps, for your kind information if domlogs are rotated on the server then it could be possible that you will miss the existing stats therefore run the command after taking all the essential files backups.

root@server [~]#/usr/local/cpanel/3rdparty/bin/webalizer /usr/local/apache/domlogs/DomainName -n DomainName

For example we are runnning the webalizer for the theperfectarts.com domain

root@server [~]#/usr/local/cpanel/3rdparty/bin/webalizer /usr/local/apache/domlogs/theperfectarts.com -n theperfectarts.com

Once above command run successfuly run the following command

How to install the imagick on cPanel server and Plesk server

Gunjan — Mon, 07 Nov 2011 01:05:18 +0000

We can install the imagick on the server by using the following command from the shell.

server@root[~]# cd /usr/local/src

server@root[/usr/local/src]#wget http://pecl.php.net/get/imagick-2.2.0.tgz

server@root[/usr/local/src]#tar -zxvf imagick-2.2.0.tgz

server@root[/usr/local/src]#cd imagick-2.2.0

Nameserver IPs not showing in WHM?

Gunjan — Tue, 28 Jun 2011 10:23:11 +0000

In recent cPanel version “Nameserver IPs” section won’t show ips. All ips are present in /etc/nameserverips file but still ips missing.

root@root[~]# cat /etc/nameserverips
198.168.0.1=ns1.test.com
198.168.0.2=ns2.test.com

In that case correct ips entry in the following /var/cpanel/nameserverips.yaml file.

root@root [~]# cat /var/cpanel/nameserverips.yaml
—
ns1.test.com:
“198.168.0.1″: 1
count: 1
zones: test.com
ns2,.test.com:
198.168.0.2: 1
count: 1
zones: test.com

Now check nameserver ips in WHM >> Main >> DNS Functions >> Nameserver IPs.

Rename package names on cPanel server.

Gunjan — Fri, 01 Oct 2010 20:57:04 +0000

Many time we like to rename package name for our hosting accounts but as hosting account is assigned to large number of user and we can’t reassign package one by one to all users as its time consuming process at that time we can refer following steps to secure time.

First login in to shell as root user.

root@server [~]# cd /var/cpanel/packages/

Now rename package for test purpose, we are renaming test_test package to test_support package.

root@server [/var/cpanel/packages]# mv test_test test_support

Now make sure that you reassign package to your users who are currently using test_test package.

root@server [/var/cpanel/packages]# cd /var/cpanel/users

Now search users who are currently using test_test package.

root@server [/var/cpanel/users]# grep test_test * -R
admin12:PLAN=test_test
test12:PLAN=test_test

Now simply run following command to replace all instance for test_test package in users file with new package name test_support

root@server[/var/cpanel/users]#grep test_test * -R -l > rename-packages

The above command will store all users name who currently using test_test package in rename-packages file.

root@server [/var/cpanel/users]# cat rename-packages
admin12
test12

Now create new file packages.sh with the following code.

root@server [/var/cpanel/users]# pico packages.sh

#!/bin/sh
dir=”/var/cpanel/users/”
fstr=”test_test”
rstr=”test_support”
exec 3<&0
exec 0<”/var/cpanel/users/rename-packages”
while read LINE ; do
sed -i “s/$fstr/$rstr/” “$LINE”
done

Set executable permission to file packages.sh file.

root@server [/var/cpanel/users]#chmod 755 packages.sh

Before running packages.sh file check one of the users file and check package name.

root@server [/var/cpanel/users]# cat admin12
# cPanel — If you edit this file directly you must run /scripts/updateuserdomains afterwards to rebuild the system caches
BWLIMIT=unlimited
CONTACTEMAIL=
CONTACTEMAIL2=
DEMO=0
DNS=server.com
FEATURELIST=default
HASCGI=1
IP=xx.xx.xx.xx
LANG=english
LOCALE=en
MAXADDON=5
MAXFTP=0
MAXLST=0
MAXPARK=0
MAXPOP=0
MAXSQL=0
MAXSUB=0
MTIME=1283914039
MXCHECK-server.com=0
OWNER=root
PLAN=test_test
RS=x3
STARTDATE=1269778722
USER=admin12

Now run file packages.sh

root@server [/var/cpanel/users]#./packages.sh

After running packages.sh file you can check user file name and found out that package name is changed.

Note : The above steps useful to rename packages for users , it will not change any value like addon , parked domain limit etc.

Internal Server Error “cPanel user” is over quota.

Gunjan — Wed, 19 May 2010 19:27:27 +0000

Some time we receive following error message while browsing webmail etc.

To resolve above error refer following steps.
root@server[~]#cd /var/cpanel/overquota/

root@server [/var/cpanel/overquota]#ll | grep your_cpanel_user_name

Once you found out file for your cPanel user name either remove the file or rename it like cpanel_user_name-back etc.

And now browse your webmail but make sure that you have increased disk space for your domain if its really exceeded.
