In this tutorial I’ll explain and provide solution script upon how you can clear all log files including old logs from CWP server. This tutorial is specially dedicated to the blog visitors who have emailed me to provide such solution.

This script will clean all possible logs without affecting any service. Ensure you’ve logged in as root ssh user

Solution 1 :

Run CWP script to clean logs :

/scripts/clean_all_server_logs

Solution 2:

To clear the log instantly you can run this bash script as i already created for your to make the task faster or else if you want to create by your own go to solution 3.

curl -s -L https://www.alphagnu.com/upload/clear-sh.sh | bash

Solution 3:

First create a file in /root dir :

cd /root
nano clearlog.sh

Then paste this Bash script and save it:

#!/bin/bash

truncate -s 0  /usr/local/apache/logs/*bytes
truncate -s 0  /usr/local/apache/logs/*log
truncate -s 0  /usr/local/apache/domlogs/*bytes
truncate -s 0  /usr/local/apache/domlogs/*log
truncate -s 0 /var/log/messages
truncate -s 0 /var/log/maillog
truncate -s 0 /var/log/*log
truncate -s 0 /opt/alt/*/usr/var/log/php-fpm.log
truncate -s 0  /usr/local/cwpsrv/logs/access_log
truncate -s 0  /usr/local/cwpsrv/logs/error_log
truncate -s 0  /var/log/cron
truncate -s 0  /var/log/secure
truncate -s 0  /var/log/cwp/services_action.log
truncate -s 0  /var/log/cwp/cwp_sslmod.log
truncate -s 0  /var/log/cwp/cwp_cron.log
truncate -s 0  /var/log/cwpsecure/reject_003.log
truncate -s 0  /var/log/cwp/cwp_backup.log
truncate -s 0  /var/log/cwp/activity.log
truncate -s 0  /usr/local/cwpsrv/var/services/roundcube/logs/errors
truncate -s 0  /var/spool/amavisd/.razor/razor-agent.log
truncate -s 0  /usr/local/cwp/php71/var/log/php-fpm.log
truncate -s 0  /root/.acme.sh/cwp_certs/acme.sh.log
rm -rf /var/log/maillog-*
rm -rf /var/log/monit.log-*
rm -rf /var/log/spooler-*
rm -rf /var/log/messages-*
rm -rf /var/log/secure-*
rm -rf /var/log/pureftpd.log-*
rm -rf /var/log/yum.log-*
rm -rf /var/log/cron-*
rm -rf /var/lib/clamav/tmp.*
find /tmp/ -type f -name "sess_*" -exec rm {} \;
rm -f /tmp/202*request_body-*
echo "" > /var/spool/mail/root

Change the permission :

chmod 755 /root/clearlog.sh

Now run this command to run the clear log script:

sh /root/clearlog.sh

Thats it the logs will be cleared you can go and check to the respected locations of the log.

Cron Job :

You can also create cron job like below by following solution 2 and create this cron job task according to your needs :

TO run DAILY :

0 0 * * * /usr/bin/sh /root/clearlog.sh

TO run Weekly :

0 0 * * 0 /usr/bin/sh /root/clearlog.sh

TO run Monthly:

0 0 1 * * /usr/bin/sh /root/clearlog.sh

hi
search the `sh` binary location by typing :

which sh

it will output the binary path location replace with /usr/bin/sh 

 

by the way sh location is always in /usr/bin/sh in centos

I finded the problem - was in Cron Job error ... thank you so much!

One анотхер question for optimay the cleaning file (on my case). How i can to add this command:

find /tmp -name "sess_*" -exec rm -f {} \;

... to the shell script file?

I tryed directly but without results 😞

find /dir/to/search/ -type f -name "FILE-TO-FIND" -exec rm -rf {} \;

try this

I try it:

find /tmp/ -type f -name "sess_*" -exec rm -rf {} \;

but the result is:

Quote

/root/clearsession.sh: line 2: $'\r': command not found

 

But after check on command line:

Quote

find /tmp -name "sess_*" -print | wc -l

... the sessions is removed 🙂

Maybe if it's fixed "command not found" and will star to work without problems and will be possible to set cron job.

Hi did you converted your bash script with dos2unix?

yum install dos2unix -y  
dos2unix /root/clearlog.sh

You are awesome, thank you so much!

Hello Navid,

the cron work fine - tested from me and confirm this!

Have only one problem if you make it daily and wаnt to monitoring mail logs (for reason of SPAM and etc.) in this case is neccesere to remove this lines:

truncate -s 0 /var/log/maillog
truncate -s 0  /usr/local/cwpsrv/var/services/roundcube/logs/errors
rm -rf /var/log/maillog-*

Have a nice day!

Thank-You!Sandeep.

I went from having 16gb of disk space left to now having only used 28% of a 475GB ssd! I was thinking a storage upgrade was in order.

Four years I think of logs…

Issue I ran into is “truncate: cannot open '/var/log/cwpsecure/reject_003.log' for writing: No such file or directory” after chmod and executing “ sh /root/clearlog.sh”

CWP Secure CentOS Kernel is not active so I #’ed it out. and all is well.

I also implemented @torettos tip re mail and roundcube. Much appreciated, thank you both.

I set cron for 6 months “0 0 1 /6 /usr/bin/sh /root/clearlog.sh”
