FATAL error while starting VPS

FATAL error while starting VPS

=========
Problem:

Error "FATAL: kernel too old" while creating VPS with Fedora Core 5.

Solution:

Fedora Core 5 is compiled to require kernel 2.6.9. Still, it works fine with OpenVZ stable kernel based on 2.6.8. You can solve this problem by using following command:

echo 2.6.9 > /proc/sys/kernel/virt_osrelease

Increase max emails per hour for a single domain in cPanel

You can change the maximum number of emails allowed for a specific domain from the system default by editing the backend file.

vi /var/cpanel/maxemails

Simply add the entry “domain.com = 100". This sets the limit to 100 emails per hour for domain.com.

Remember to run the following script after updating /var/cpanel/maxemails:

/scripts/build_maxemails_config

myisamchk “A super tool to view and repair corrupt databases”

myisamchk “A super tool to view and repair corrupt databases”

The myisamchk utility gets information about your database tables or checks, repairs, or optimizes them. myisamchk works with MyISAM tables (tables that have .MYD and .MYI files for storing data and indexes).
Caution
It is best to make a backup of a table before performing a table repair operation; under some circumstances the operation might cause data loss. Possible causes include but are not limited to file system errors.
To find the tables that are corrupt and to output it to a file run the following script

find -name “*.MYI” -exec myisamchk -c {} \; > /root/tbl_chk

To view the number of tables corrupt

cat /root/tbl_chk | grep MyISAM | wc -l

To repair the corrupt tables

find / -name “*.MYI” -exec myisamchk -r {} \;
