Installation ::

root@server[#] yum install mailx -y
root@server[#] wget http://download1.obs.j0ke.net/hardware:/raid/openSUSE_10.3/i586/sas2ircu-5.00.00-1.1.i586.rpm
root@server[#] rpm -ivh sas2ircu-5.00.00-1.1.i586.rpm

And once the above RPM gets installed then you can check the Raid Array Status using the below command ::

 root@server[#] sas2ircu 0 DISPLAY

Use sas2ircu  –help for available options.

Configuration ::

Add the below simple script in the /etc/cron.daily directory so that you can receive daily notification for Raid Array Status.

#!/bin/sh

Email="client's email address"
echo "#############  RAID ARRAY STATUS ON `hostname` `date` #############" > /root/raidstatus

      sas2ircu 0 DISPLAY >> /root/raidstatus
echo "##############################################################" >> /root/raidstatus
  mail -s "RAID Array Status on `hostname` server :: `sas2ircu 0 STATUS | grep state | awk {'print $4'}` " $Email<  /root/raidstatus

exit 0

That’s all you are done.

Table 'mybb_datacache' is marked as crashed and should be repaired
 Query: SELECT title,cache FROM mybb_datacache

And if you have tried restoring the database from your backup.sql file but still getting the same error then don’t panic because this can simply be resolved from phpMyAdmin,by running the following query:

REPAIR TABLE mybb_datacache;

That’s all easy isn’t it .

But when you try  to manually execute the php file from  the server using the php command as

root@server[public_html]# php  index.php

File size limit exceeded (core dumped)

you will get  the above error and now you start thinking what on earth is that .

Reason for that ?

 

The reason  for that error is that one of the file probably a log file under that domain exceeds to  2 GB and  by default Apache has setting enabled, to display 500 Internal  Server Error if  in case any file under a domain exceeds 2 GB.

How to fix ?

Just either remove that file or echo that file and you are done.

Tried the above fix  but still  not working ?

In that case, I  suggest you to check  all  the apache logs files specially error_log, suphp_log, suexec_log and modsec_audit.log and if you found any log file over 2 GB then just remove/echo  that file and restart apache service and you are done. 

That’s all

checking whether the C compiler works… configure: error: cannot run C compiled programs.

Then it means that the executable permission is not set on /tmp or /var/tmp

  root@server[~]# mount | grep /tmp
 /usr/tmpDSK on /tmp type ext2 (rw,noexec,nosuid)
 /tmp on /var/tmp type none (rw,noexec,nosuid,bind)

So, in-order to complete the pecl installation just remount the /tmp and /var/tmp with executable permissions as :

root@server[#] mount -o remount rw /tmp

root@server[#] mount -o remount rw /var/tmp

And now just try the pecl install uploadprogress and it will work like a charm.

That’s all you are done.

Login to WHM  >> Main >> SQL Services >> MySQL Root Password 

and then reset the mysql root password and now try to installing any application  from Softaculous Panel it will no longer show any error.

And if you still face the same error then make sure that you have not disabled the Database Prefix in WHM .

You can refer the below URL to  re-enable the database prefix  if you mistakenly disabled the database prefix in WHM. 

http://www.linuxspy.com/1208/the-database-prefix-option-has-been-disabled/

That’s all you are done.

You can fix  this by  simply running the below command as root user : 

/usr/local/psa/bin/sso --disable

That’s all you are done.

instmodsh command provides an interactive shell interface to query details of locally installed Perl modules.

root@server[#] instmodsh

you will get the output like ::

Available commands are:
   l            - List all installed modules
   m <module>   - Select a module
   q            - Quit the program
cmd?

at cmd ? command prompt type l to get list of all installed perl modules

Output ::

cmd? l
Installed modules are:
   Acme::Spork
   AppConfig
   Archive::Tar
   Archive::Tar::Streamed
   Archive::Zip
   Attribute::Handlers

Copy the above script in a .sh file like listreseller.sh and allow executable permission to listreseller.sh file and then execute it as :

root@server[#] ./listreseller resellerusername

or

root@server[#] ./listreseller  resellerdomain.com

After executing the script you will get the below output as ::

root@server[#] ./listreseller test.com
 ==========================================================
 Below are the accounts associated with the reseller
 ==========================================================
 test
 raj
 sunil

or

 root@server[#] ./listreseller newtest
 newtest is not a reseller

That’s all.

To fix the issue you need to correct the entries for the name-server’s IP in the below two files ::

1>

/etc/nameserverips

2 >

 /var/cpanel/nameserverips.yaml

Firstly, check the entries in the /etc/nameserverips file and it should show the below output ::

root@server [~]# cat /etc/nameserverips

192.168.1.1=ns1.yourdomain.com
192.168.1.2=ns2.yourdomain.com

And if the entries in the above files are correct then check the next file it should show the below output ::

root@server [~]# cat /var/cpanel/nameserverips.yaml
---
ns1.yourdomain.com:
"192.168.1.1": 1
count: '1'
zones: yourdomain.com
ns2.yourdomain.com:
"192.168.1.2": 1
count: '1'
zones: yourdomain.com

If the above entries are missing in the above file then add those as shown in the example.

That’s all.

For this all you need to do is to copy all the domains hosted on the server in a  text file.

For cPanel  you can copy all domains in a .txt file  using the below command :: 

root@server[#] cat  /etc/userdomains | awk '{print $1}' | tr -d ':|*' > domainlist.txt

For Plesk you can copy all domains in a .txt file  using the below command ::

root@server[#] cd /var/qmail/mailnames ;  ls -l  awk '{print $9}' > domainlist.txt

And for  Plain server you can copy all  the domains in a domainlist.txt file

Now, that we have all the domain names copied in  the domainlist.txt file  we  just need to  execute the below script from shell  as a root user 

root@server[#] for i in `cat domainlist.txt`; do host $i | grep 'not found|has IP address';  done

The above command will list the results as ::

test.com has address 192.168.0.1

testing.com has address 192.168.0.2

That’s all.
