Invalid command ‘<IfVersion’, perhaps misspelled or defined by a module not included in the server configuration
The above error is due to missing mod_version which needs to be added in apache using easyapache
it was fixed once the mod_version module was added

Went ahead and restart mysql.. Mysql was online

We had attempted a dual boot vps on KVM based vps
The os were installed using ISO
First to start with windows and then linux
However after installing linux the windows OS went missing
ON googling around found a solution
The issue was due to missing modules where we had to install module ntfs-3g

we had to use epel repository to install ntfs-3g as its not available with normal repository

if windows is not found the OS may have got formatted while installing other OS
However our windows os was intact as the results show
#make backup copy of grub.conf
sudo cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.old
#Recreate the grub.conf to load windows and linux os using below command
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
and now reboot and see both OS load
While trying to unmount a secondary drive I see below error

(In some cases useful info about processes that use

The ‘SMTP AUTH’ error usually happens when users try to send mails without properly authenticating their mail account in email clients such as Outlook or Thunderbird.
With the latest cPanel/WHM update, email accounts that were working fine till now, may find their mails getting undelivered, showing this error message in the Exim log:
2018-01-17 05:57:40 H=(cruxserver12.com) [174.136.14.87]:63927 F=<zimphost@gmail.com> rejected RCPT <technical424@gmail.com>: SMTP AUTH is required for message submission on port 587
2018-01-17 05:58:09 H=(cruxserver12.com) [174.136.14.87]:63932 F=<zimphost@gmail.com> rejected RCPT <technical424@gmail.com>: SMTP AUTH is required for message submission on port 587
This has happened due to a latest security feature implemented in cPanel/WHM – ‘SMTP AUTH’ requires SSL by default.
To combat spamming in servers and to provide secure email transmission, email clients that try to send mails without using secure transmission will be denied mail delivery through the server.
The option that determines this is ‘Require clients to connect with SSL or issue the STARTTLS command before they are allowed to authenticate with the server’, which is set to ‘On’ by default, in WHM -> Exim Configuration Editor.
Setting it to Off will fix this issue 🙂
While activating a new account I could see an error
“Your system has run out of available ip addresses, or you do not have permission to use any more ip addresses”
The issue was due to the server running out of spare dedicated IP address
The issue can be resolved in 2 ways
1) Adding additional IP address in server
2) By editing file /var/cpanel/packages/abckhosting which is a package file which is assigned to customers.
SSH to server in question on which account is activated and edit the package file as mentioned
vi /var/cpanel/packages/abckhosting
The parameter IP=y needs to be changed to IP=n to get account activated without adding new IP address.
BWLIMIT=unlimited
CGI=y
CPMOD=paper_lantern
DIGESTAUTH=n
FEATURELIST=default
HASSHELL=n
IP=n
LANG=en
MAXADDON=5
MAXFTP=5
MAXLST=unlimited

MAXPOP=unlimited
MAXSQL=10
MAXSUB=5
MAX_DEFER_FAIL_PERCENTAGE=unlimited

This did help in creating new account without adding additional IP address
Was getting below error on cpanel server even when cpanel license was assigned for main server IP address
root@server4 [/etc/sysconfig/network-scripts]# /usr/local/cpanel/cpkeyclt
Updating cPanel license…Done. Update Failed!
Error message:
The cPanel license server said that there was no license for your IP address.
For more information visit: http://www.cpanel.net/lic.html
The exact message was: Abort, Retry, Fail?
Building global cache for cpanel…Done
The issue was due to wrong entries in /etc/hosts file
went ahead and set the correct hostname and IP in /etc/hots file and refreshed cpanel license
root@server4 [/etc/sysconfig/network-scripts]# /usr/local/cpanel/cpkeyclt

Below steps are for Centos 7
yum -y install epel-release
rpm –import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release0-5.el7.nux.noarch.rpm
yum -y install ffmpeg ffmpeg-devel
Below steps are for Centos 6
yum -y install epel-release
rpm –import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
wget https://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-1.el6.nux.noarch.rpm
rpm ivh nux-dextop-release-0-1.el6.nux.noarch.rpm
yum -y install ffmpeg ffmpeg-devel
now we need to install ffmpeg-php to get it working using PHP
yum -y install git
git clone https://github.com/tony2001/
If you want to install on PHP 7 use
[Usually before easyapache 4 only phpize would work] now as there are multiple version of PHP there is need to phpize from above path.
The path would changes based on php version
if you are using PHP 7 path will be /opt/cpanel/ea-php70/root/usr/bin/phpize and
/opt/cpanel/
You can find path using find command
[root@server ffmpeg-php]# find / -iname phpize
/opt/cpanel/ea-php55/root/usr/bin/phpize
/opt/cpanel/ea-php56/root/usr/bin/phpize
/opt/cpanel/ea-php70/root/usr/bin/phpize
Do not use path ./usr/local/cpanel/3rdparty/bin/phpize
Before compiling ffmpegphp
need to make sure all need files are in /usr/include
When you install ffmpeg and ffmpeg-devel files get stored in /usr/include/ffmpeg however ffmpeg while compiling looks for files in /usr/include/ so need to copy files to /usr/include using below command
scp -r /usr/include/ffmpeg/* /usr/include/
Now you can go ahead and compile
./configure –with-php-config=/opt/cpanel/ea-php56/root/usr/bin/php-config
Note [Path /opt/cpanel/ea-php56/root/usr/bin/php-config will changed on which version you are installing ffmpeg]
[root@server ffmpeg-php]# find / -iname php-config
/opt/cpanel/ea-php55/root/usr/bin/php-config
/opt/cpanel/ea-php56/root/usr/bin/php-config
/opt/cpanel/ea-php70/root/usr/bin/php-config
now before making make and make install few things need to be modified.
mv /usr/include/libavutil/time.h /usr/include/libavutil/time.h_
now go ahead with make and make install
now again need to rename the above file
mv /usr/include/libavutil/time.h_ /usr/include/libavutil/time.h
ffmpeg modules will be installed in below path
root@server ffmpeg-php]# ls -al /opt/cpanel/ea-php56/root/usr/lib64/php/modules/
total 2712
drwxr-xr-x 2 root root 4096 Dec 7 07:07 .
drwxr-xr-x 4 root root 4096 Feb 22 2017 ..

-rwxr-xr-x 1 root root 57792 Feb 22 2017 ftp.so
Now go ahead and add extension=ffmpeg.so to php.ini for the PHP version you need and restart apache
