To easily kill all processes running under a user
ps -u USER | awk ‘{print $1}’ | xargs kill -9
or
pkill -u USER
replacing USER with the username.
To kill all specific processes such as php running under a user run,
ps -u USER | grep PROCESS |awk ‘{print $1}’ | xargs kill -9
replacing USER with username and PROCESS with php or any other process.
NEVER DELETE ANY FILES FROM /home/virtfs/
/home/virtfs is used to chroot the user into jailed shell. Cpanel will hard link files into this directory so deleting files in /home/virtfs will also delete the files on the server in the actual location. (example: rm /home/virtfs/user/etc/exim.pl will delete /etc/exim.pl)
If a user is reporting double the quota and it is from /home/virtfs then we need to umount or kill and hanging jailshell process. To do this run
ps aufx |grep user |grep jailshell
If there are no jailshell processes then run
cat /proc/mounts
It will show,
/dev/root /home/virtfs/user/lib ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/lib ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/sbin ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/share ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/bin ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/man ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/X11R6 ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/kerberos ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/libexec ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/local/bin ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/local/share ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/local/Zend ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/include ext3 rw,data=ordered,usrquota 0 0
/dev/sda2 /home/virtfs/user/usr/local/lib ext3 rw,data=ordered,usrquota 0 0
/dev/sda3 /home/virtfs/user/var/spool ext3 rw,noatime,nodiratime,data=ordered,usrquota 0 0
/dev/sda3 /home/virtfs/user/var/lib ext3 rw,noatime,nodiratime,data=ordered,usrquota 0 0
/dev/sda3 /home/virtfs/user/var/run ext3 rw,noatime,nodiratime,data=ordered,usrquota 0 0
/dev/sda3 /home/virtfs/user/var/log ext3 rw,noatime,nodiratime,data=ordered,usrquota 0 0
/dev/sda6 /home/virtfs/user/tmp ext3 rw,nosuid,nodev,noexec,data=ordered 0 0
/dev/root /home/virtfs/userbin ext3 rw,data=ordered,usrquota 0 0
You will need to unmount each of these by running
umount /home/virtfs/user/tmp and so on
You can also run
for i in `cat /proc/mounts |grep virtfs |grep user |awk ‘{print$2}’`; do umount $i; done
Make sure to replace user with the cpanel username in the above command. This will then clear up the files in /home/virtfs and the quota should return to normal.
If you are trying to use the ForceType directive in your .htaccess files with PHPsuexec, it will fail. To work around this, simply use SetHandler instead of ForceType.
example:
<Files r>
SetHandler application/x-httpd-php
</Files>
or
SetHandler application/x-httpd-php
The first one listed will cause files named “r” to be executed as PHP scripts, same as if it is named r.php basically. The 2nd example will parse every file through php.
Login to WHM as root and go to tweak settings. Under the Myql Section click version 5.0. Login to the server through shell and run
/scripts/mysqlup
Once this is completed, make sure mysql 5 has started, run
mysql
If it fails to connect run
/etc/init.d/mysql start
If it fails to start edit the /etc/my.cnf and commend out the line Basedir=/var/lib/mysql and then start mysql
Once you have mysql 5 fully started you must recompiled php to work with the new mysql errors. You can either do this from source or from easyapache whichever you are more comfortable with. If you choose easyapache make sure you select option #7 from the easy apache menu and you do not need to make any changes.
To export a database run
mysqldump datbasename > databasename.sql
This will export the database to databasename.sql
To import a database from an sql dump file run
mysql databasename < dumpsqlfilename.sql
This will import the sql file into the database. Once imported you should check to make sure it was correctly imported to do this run
mysql databasename
show tables;
If the you do not see any tables listed then the sql file likely has a USE statement at the top. Edit the sql file with a text editor and comment out the line “USE databasename”. Once commented out attempt to import the data and check the tablesl.
