Was getting above error in mysql errorlog

The solution to this issue was just to go ahead and delete tc.log

rm -rf /var/lib/mysql/tc.log

Went ahead and restart mysql.. Mysql was online

root@server lib]# rm -rf /var/lib/mysql/tc.log
[root@server lib]# /etc/init.d/mysql restart

Column count of mysql.user is wrong

Was getting below error while trying to create mysql user in cpanel

Error from MySQL query :(XID 5yuvwf) The system received an error from the “MySQL” database “mysql”: 1805 (Column count of mysql.user is wrong. Expected 43, found 39. The table is probably corrupted):

The migration used a “mysqldump –all-databases” so it included the “mysql” database. Apparently the “mysql.proc” table changed between the versions. The fix on the new server is to run:

Below command fixed the issue

mysql_upgrade —force

The system could not create the user “triltch” because it conflicts with an unmanaged MySQL database user and an unmanaged PostgreSQL database user

While creating a new account in server was getting below error

The issue was due to mysql user already being present in server

This ok? yes

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

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

Secure Connection Failed while accessing IPMI

Secure Connection Failed

An error occurred during a connection to 216.1x.1xx.xxx. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.

Firefox stores certificates separately from the Operating System. Sometimes the certificate store can become corrupt and won’t let you delete certificates. To solve this, you’ll have to reset it manually.

Go to Start > Run

Type %appdata% and click Ok.
Result: A folder should open up.

Now go to Mozilla, then Firefox, then Profiles, and choose your profile folder (it probably is named a random string of letters, often followed by .default).

Delete the file called “cert8.db”.

This should fix the issue .

Disable WordPress plugins from PHPmyadmin

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.

Cloudflare with Engintron

We had a issue where domain which is using cloudflare and server had engintron those domains were not working correctly

Engintron does support Cloudflare . There are few custom rules which needs to be setup from

WHM > Plugin > Emgintron > Edit your custom_rules for Nginx

For domains which have dedicated IP below is the rule which needs to be added

if ($host ~ “oxyxxxxx.com”) {
set $PROXY_DOMAIN_OR_IP “173.1xx.xx5.xxx”;

}

Where you need to set right domain name and right IP associated with domain

If using a shared IP address below is the rule that needs to be added in

Edit yourcustom_rules for Nginx and add below statement

set $PROXY_DOMAIN_OR_IP “XXX.XXX.XXX.XXX”;

Where you need to set shared IP in above example

mysqldump: Got error: 1017: Can’t find file: ‘wp_wfBadLeechers’ (errno: 2) when using LOCK TABLES

While making full backup of mysql using below command we got error

mysqldump: Got error: 1017: Can’t find file: ‘wp_wfBadLeechers’ (errno: 2) when using LOCK TABLES

# mysqldump –all-databases > /backup/all_databases.sql

The issue was due to some corrupt tables

Below is the fix used for making a full dump of database ignoring error

mysqldump –skip-lock-tables -f –all-databases > /backup/all_databases.sql

Mysql backup was completed ignoring the corrupt tables.

Your server’s MySQL/MariaDB RPM target is set to “unmanaged”. cPanel

Was getting this error while trying to upgrade mysql in WHM/cPanel,

Your server’s MySQL/MariaDB RPM target is set to “unmanaged”. You cannot use the MySQL/MariaDB Upgrade feature while your server is in this state.

The issue was due to entry in file /var/cpanel/rpm.versions.d/local.versions set mysql to unmanaged

Went ahead and set it to managed and was able to upgrade mysql from WHM without any issues

Sorry, the domain xx.xx.104.in-addr.arpa is owned by another user (nobody)

While adding rDNS file in cpanel server I was getting below mentioned error

Sorry, the domain xx.xx.104.in-addr.arpa is owned by another user (nobody)

I have found that at one point in the past this domain was present on this server.

I have removed remnants of the domain from /var/cpanel/users/system and removed references to it from /etc/userdomains and /etc/remotedomains.

I then rebuilt the various caches:

====
/scripts/updateuserdatacache
/scripts/updateuserdomains
====

I am now able to add zone file without any issues
