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

While trying to unmount a secondary drive I see below error
umount: /backup: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
The issue was due to the drive /dev/sdb being used by some process
Below is the process on how to find process using drive and kill it and umount drive
# Command to unmount drive
root@oM1050 [/backup/weekly]# umount /backup

While creating a new account in server was getting below error
The issue was due to mysql user already being present in server
root@srv1 [~]# /scripts/wwwacct trill.com tritch hood773ud

+===================================+
| Domain: trill.com

Checking for database conflicts…(XID vh9sa4) The system could not create the user “tritch” because it conflicts with an unmanaged MySQL database user and an unmanaged PostgreSQL database user.
Steps to fix this issue
Login to WHM
Go to PHPmyadmin
Select database Mysql
Go to Option search
Select all tables inside in option Inside tables
In option Words or values to search for (wildcard: “%”): put up name of mysql user which is conflicting >>
Delete all the tables you get in search tables and issue should be resolved

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
MAXPARK=5
MAXPOP=unlimited
MAXSQL=10
MAXSUB=5
MAX_DEFER_FAIL_PERCENTAGE=unlimited
MAX_EMAIL_PER_HOUR=unlimited
QUOTA=100000
_PACKAGE_EXTENSIONS=
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

The issue was due to wrong entries in /etc/hosts file

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 32608 Feb 22 2017 bcmath.so
-rwxr-xr-x 1 root root 33792 Feb 22 2017 calendar.so
-rwxr-xr-x 1 root root 15584 Feb 22 2017 ctype.so
-rwxr-xr-x 1 root root 86928 Feb 22 2017 curl.so
-rwxr-xr-x 1 root root 180728 Feb 22 2017 dom.so
-rwxr-xr-x 1 root root 281640 Dec 7 07:07 ffmpeg.so
-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
While trying to change main IP of server was facing issue
Where was getting message IPAddress is already an active IP
On checking around found the below solution which worked
Make sure that the IP address you’re trying to add has been removed from these files:
/etc/hosts
/etc/ips
/etc/mail_reverse_dns
If you happen to also be trying to add back the IP that was previous the primary IP address, you will also need to update this file:
/var/cpanel/mainip
Now could add the IP address back in server
You can easily disable all WordPress plugins directly from your database. This is useful when you have problems with your WordPress installation, such as not being able to log in to the admin Dashboard, or having blank pages on the website.
If you don’t know which is the database used by your WordPress website, you can check the DB_NAME variable in the WordPress configuration file – wp-config.php. This file is usually located in the document root directory of your application and can be opened via the File Manager in cPanel.
To disable all plugins, go to phpMyAdmin in cPanel and select your WordPress database from the menu on the left.
Browse the table wp_options and find the option active_plugins. Click the pencil icon to edit the table. Its content will vary, depending on what plugins you have enabled. For example, if you have the Akismet and Hello Dolly plugins enabled, the code there will be:
|
1
|
a:2:{i:0;s:19:“akismet/akismet.php”;i:1;s:9:“hello.php”;}
|
To disable all plugins, simply delete the code and click the Go button to save the change.
Please note that this table may have a different prefix instead of wp_. You will see the correct prefix of the database once you access the phpMyAdmin tool and select the the WordPress database.
Disabling the plugins in this way will not delete them from your WordPress application. They will simply be deactivated. You can easily activate them from your WordPress admin area at any time.
