How to remove error_log from all CPanel account and backups

April 25th, 2015 by EZ linux · No Comments

Some scripts like WordPress and Joomla can leave a big error_log files that no one will ever look at. Try opening a 30mb log file with Word and see what happens. In most cases you can just remove this file with a simple command.

To remove all error_log files for CPanel accounts that are live use:

find /home/ -type f -name error_log -delete

To remove all error_log files from backups use:

find /backup/ -type f -name error_log -delete

This will take a while to complete because it will look through every file, it also runs pretty smooth so just sit back and let it work it’s magic.

How to change the main IP on a CPanel server

April 24th, 2015 by EZ linux · No Comments

Changing a server to a new IP is a nightmare, there is so many places that need to update. If possible always just set up a new server and transfer everything to it. If that’s too hard than here is how to do the migration the best possible way.

  1. Edit /etc/sysconfig/network-scripts/ifcfg-eth0
    Change the IPADDR and GATEWAY lines to match the new IP and Gateway for the new ip
  2. Edit /etc/sysconfig/network
    Change the GATEWAY line here if it does not exist in the ifcfg-* file.
  3. Edit /etc/ips
    Remove the new primary IP from this file if it is present
    Add the old primary IP to this file
  4. Edit /var/cpanel/mainip
    Replace the old primary IP with the new primary IP
  5. Edit /etc/hosts
    Replace the old primary IP with the new one if needed. The hostname’s dns will need to be updated too
  6. Restart the network service to make the new IP the primary: service network restart
    (Note: You’re probably going to be disconnected at this point, and have to log in to ssh using the new primary ip.)
  7. Restart the ipaliases script to bring up the additional IPs: service ipaliases restart
  8. Run ifconfig and make sure all IPs show up correctly
  9. Update the cpanel license to the new primary IP
  10. Then run /usr/local/cpanel/cpkeyclt to update the CPanel license
  11. Then run the migration Wizard inside CPanel to update Apache and the website settings.

In a perfect world that will do it.

Good luck!

FTP not working, stops at MLSD

March 17th, 2015 by EZ linux · No Comments

The firewall blocks passive mode FTP transfers.

To fix this error you need to:

open: /etc/pureftpd.conf

Find: PassivePortRange in /etc/pureftpd.conf

Remove the # and add this to the line: PassivePortRange 30000 35000

See TCP_IN in /etc/csf/csf.conf and add the passive port range to it

TCP_IN = “##,##,##,###,###,###,30000:35000″

Notice in TCP_IN you see 30000:35000 , that’s a range of ports. And based upon what you set for the PassivePortRange in /etc/pureftpd.conf, you should modify TCP_IN in /etc/csf/csf.conf to allow those inbound ports.

Next you need to restart both PureFTP and CSF after making the changes.

Cphulk blocked you?

February 7th, 2015 by EZ linux · No Comments

Here is how to flush the database for Cphulk from the command line. You can’t whitelist IPs this way but running this command will flush all blocks and get you into the WHM (WebHostManager) to whitelist your IP. You will need root access to do this.

 

echo "delete from brutes; delete from logins;" | mysql cphulkd

Free space on a CPanel/WHM server with root access

May 27th, 2014 by EZ linux · No Comments

Cleaning up and making space on /usr

1. Restart the httpd service. This might free a little space some times.

2. Check for Apache logs like error_log, access_log , suexec_log in /usr/local/apache/logs . These can either be cleared off or if you need the logs then you can take a zipped copy and keep it aside.

3. Same can be done for the files in cPanel logs (/usr/local/cpanel/logs) as well .

4. Domlogs – Get into the /usr/local/apache/domlogs/ directory. Run the following command :-

# ls -al -SR | head -10 —> It will list 10 files in the decreasing order according to their size

If the domlog file is too large for a domain then it is possible that awstats is not running . Check whether cpanellogd is running on the server using pstree . If not, restart it .
Else, it is possible that awstats for only that particular domain is not updating. Get into the directory /usr/local/cpanel/base and check if any file as ‘awstats.domainname.com.conf’ exists. If yes , delete that file.

Now, run /scripts/runweblogs for that user. It will update the awstats and automatically clear the domlogs file thereafter. Do not delete the domlogs file itself.

5. Remove old and unwanted backups of ‘apache’ that might have been taken long ago. Also, check for any other duplicate folders that can be removed safely.

6. Remove core files, if any . Normally, some core files (like core.1234) might be present in /usr/local/cpanel/whostmgr/docroot . Check for these and remove them.

7. Restart your server, the quota might be off for that partition and reboot will correct it. Keep in mind if there is a hard drive error this can leave the server offline while the system or admin tuns a FSDK.

Cleaning up and making space on /var

Cpanel and Linux leaves a lot of log files in /var
After several years these can add up, especially in the cpanel/bandwidth folder. So a couple quick folder moves and symlinks can clean things up. This is assuming you have a /backup partition and some room in it.

1. Moving the log folder

mv /var/log /backup/
ln -s /backup/log /var/log

2. Moving the cpanel bandwidth folder

mv /var/cpanel/bandwidth /backup/
ln -s /backup/bandwidth /var/cpanel/bandwidth

3. Also just removing some of the log files in the log folder can help you for a quick fix.

4. You can use this command to find any other large folders:

du -ax –max-depth 1 /var | sort -n | tail

5. In some cases you just need to clean your mail queue

/usr/sbin/exiqgrep -i | xargs /usr/sbin/exim -Mrm

Other server cleaning tips:

1. Delete cPanel File Manager temp files

When users upload files in File Manager within cPanel, File Manager creates a temp file that may or may not get removed upon upload. You can remove these files using this command:

rm -fv /home/*/tmp/Cpanel_*
2.  Remove cPanel update archives

Cpanel and EasyApache updates tend to leave behind files that you probably don’t need. The following can be deleted or moved to a backup server to free up a little bit of space:

/usr/local/apache.backup*

/home/cpeasyapache (actual name may vary depending on cpanel version)

3.  Clean up Yum files

Yum updates leave package cache files on the server. You can clean up all unneeded yum files by running:

yum clean all

4. Remove pure-ftp partials

When your users upload files to the server via FTP when your server runs pureFTP as an FTP daemon, the FTP server creates temporary files starting with .pureftpd-upload* that get renamed the the actual filename when the upload completes. If the upload doesn’t complete, these files are left on the server. You can find and delete these by running:

locate .pureftpd-upload | xargs rm -fv
