General Shit
.htaccess
to enable the reading of the custom php.ini in the public_html for suphp you need to add the following and replaces username with the cpanel user's username
suPHP_ConfigPath /home/username/public_html
then
cd /home/username/public_html cp /usr/local/lib/php.ini /home/username/public_html/php.ini touch phpinfo.php && echo "<?php phpinfo(); ?>" >> phpinfo.php chown username. php.ini phpinfo.php
Now add you custom changes for that account into that php.ini, and then proceed to test by going to that users website/phpinfo.php and see it your changes are there.
Adding domains to Dedicated ips
To place more that one domain on a dedicated IP go to:
cd /var/cpanel/userdata/
Choose the domains user that we are adding to the ip example: username/domain.com
vim username/domain.com
Change the ip to the new ip, save the file.
/scripts/rebuildhttpdconf /etc/init.d/httpd stop /etc/init.d/httpd stop /etc/init.d/httpd startssl
Wait for it to propagate, and viola!
Addon domain issues
If you come across this error:
" Error from park wrapper: Using nameservers with the following IPs: 174.132.129.99,174.132.129.98 Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver. "
go to tweak settings an check the option to:
Allow Creation of Parked/Addon Domains that resolve to other servers (i.e. domain transfers)
APF
Apf un block

CSS not loading
Come accross a page that doesnt want to load its css on a vps? Log into the server and do the following.
curl -v 'http://domain.com/(path to the css file goes here)'
If in that's response this line is returned
* transfer closed with 1386 bytes remaining to read * Closing connection #0 curl: (18) transfer closed with 1386 bytes remaining to read
OR an easier way is to use these if they return nothing, go to next step.
cat /usr/local/apache/conf/includes/* | grep EnableSendFile cat /usr/local/apache/conf/httpd.conf | grep EnableSendFile
Copy and paste the following to fix
echo "EnableSendFile Off">>/usr/local/apache/conf/includes/pre_main_global.conf /etc/init.d/httpd restart
Custom php.ini
For SuPhP First copy the php.ini over
cp /usr/local/lib/php.ini /home/(username)/public_html/php.ini chown (username). /home/(username)/public_html/php.ini
In .htaccess under public_html, add the following:
suPHP_ConfigPath /home/user/public_html <Files php.ini> order allow,deny deny from all </Files>
Note: the local php.ini REPLACES the system one, it does not override like a .htaccess setting does.
For CGI First copy the php.ini over
cp /usr/local/lib/php.ini /home/(username)/public_html/php.ini chown (username). /home/(username)/public_html/php.ini
In .htaccess under public_html, add the following:
AddHandler php-cgi .php .htm Action php-cgi /home/(username)/public_html/cgi-bin/php5.cgi
if by chance the php5.cgi does not exist please add it with the following contents.
#!/bin/sh export PHPRC=/home/(username)/public_html/php.ini exec /usr/local/cpanel/cgi-sys/php5
Disable root login
useradd lwstaff passwd (assign a password) usermod -G wheel lwstaff vim /etc/ssh/sshd_config
change PermitRootLogin = yes to no and un-comment it. restart sshd and test your work.
DNS Cheats
Adding a wildcard to every dns record
for i in `cat /var/cpanel/users/*| grep DNS|cut -d = -f 2`; do echo "* IN CNAME $i." >> /var/named/$i.db;done
Adjusting all ttls on a server to 300
#check current TTLs and serial number
grep --color -e '^\$TTL.*' /var/named/*.db
grep --color -e '[0-9]\{10\}' /var/named/*.db # this will be the serial number, 10 numbers in a row
#also check that date works as expected/is newer than the serial numbers currently existing
date +%Y%m%d%H
#the -i flag will create backups in the same directory, liquidweb.com.lwbak for example
sed -i.lwbak -e 's/^\$TTL.*/$TTL 300/g' -e 's/[0-9]\{10\}/'`date +%Y%m%d%H`'/g' /var/named/*.db
#check your work
grep --color -e '^\$TTL.*' /var/named/*.db
grep --color -e '[0-9]\{10\}' /var/named/*.db
Email
For the number of spam in all default accounts.
for i in `ls /var/cpanel/users`; do ls -d /home/$i/mail/cur && ls -l /home/$i/mail/cur | wc -l; done
horde mail update (nothing can be in account of will all get erased)
/usr/local/cpanel/bin/update-horde --force
To determine mailserver type
/scripts/setupmailserver --current
Count mail in folder
ls | wc -l
removing mass spam
rm -Rf /home/(user here}/mail/cur*
And if that command fails, and only if that command fails try this one.
DO NOT IGNORE you MUST be in the directory that the spam is in or this command could ruin this server...
find . -type f | xargs rm -f
spam removal script
for i in $(find . | xargs grep -m 1 -s -i "Mailer-Daemon" | sed -e 's/\.\/[A-Z0-9a-z]\/\([A-Z0-9a-z\-]\{16\}\)\-[HDJ].*/\1/'); do exim -Mrm $i;done
List all email accounts on the server
for domain in `grep DNS /var/cpanel/users/* |grep DNS|cut -d = -f 2`; do for user in `cat /home/*/etc/$domain/passwd|cut -d : -f 1`;do echo $user@$domain ;done;done 2> /dev/null
List all email accounts on the server and place in a text file
for domain in `grep DNS /var/cpanel/users/* |grep DNS|cut -d = -f 2`; do for user in `cat /home/*/etc/$domain/passwd|cut -d : -f 1`;do echo $user@$domain ;done;done 2> /dev/null > EMAILLIST.txt
Fix the symlinks on the email accounts so that they show up in main account veiw.

History Removal commands
If the customer would like their history cleared.
echo "" > /var/log/messages && echo "" /var/log/secure echo "" > /var/log/wtmp && echo "" > /var/log/lastlog && history -r
If for some reason you ever need to cover your own tracks, like creating a usre on the wrong server or such, this will remove your session history
history -r

Checking swaps memory usage
vmstat 1
If digging into swaps memory run this and see if there are any tables that are "[!!] Total fragmented tables" If it does show that there are fragmented tables, run an optimize on the tables.
wget mysqltuner.pl/mysqltuner.pl && perl mysqltuner.pl
Optimization script here
for i in $(mysql -e "show databases;" | sed 's/Database//') ; do for each in $(mysql -e "use $i; show tables;" \ | sed 's/Tables.*//' ;) ; do mysql -e "use $i ; optimize table $each" ; done ; done
Using Sar
this can be helpful in figuring out what the swaps are are or the iowait.
sar
This will display Collected, report, or save system activity information.
sar -r
This will show you the memory and swap space utilization statistics.
You can futher clean that up to show just mem used and swpused with the following.
sar -r | awk '{print $1,"\t"$2,"\t"$5,"\t\t"$10}'
You can also use sar to view previous days log files. Do the following.
cd /var/log/sa ll
This should provide you with a list that looks like the following.
-rw-r--r-- 1 root root 484640 Aug 1 15:51 sa01 -rw-r--r-- 1 root root 484176 Aug 2 23:50 sa02 -rw-r--r-- 1 root root 228576 Aug 3 11:00 sa03 -rw-r--r-- 1 root root 490992 Jul 26 23:50 sa26 -rw-r--r-- 1 root root 490992 Jul 27 23:50 sa27 -rw-r--r-- 1 root root 490992 Jul 28 23:50 sa28 -rw-r--r-- 1 root root 481232 Jul 29 23:50 sa29 -rw-r--r-- 1 root root 490992 Jul 30 23:50 sa30 -rw-r--r-- 1 root root 485104 Jul 31 15:37 sa31 -rw-r--r-- 1 root root 491873 Aug 1 23:53 sar01 -rw-r--r-- 1 root root 491907 Aug 2 23:53 sar02 -rw-r--r-- 1 root root 498737 Jul 25 23:53 sar25 -rw-r--r-- 1 root root 498737 Jul 26 23:53 sar26 -rw-r--r-- 1 root root 498737 Jul 27 23:53 sar27 -rw-r--r-- 1 root root 498737 Jul 28 23:53 sar28 -rw-r--r-- 1 root root 489709 Jul 29 23:53 sar29 -rw-r--r-- 1 root root 498737 Jul 30 23:53 sar30 -rw-r--r-- 1 root root 493163 Jul 31 23:53 sar31
Each of those files is a log for that day of the month. Pick and choose then view them with the following command.
sar -f sa01
If you want to view different modes of the sar add the flags at the end of the command like so.
sar -f sa01 -r
check the parent for oomage figure out the instance id
vzlist -a
place id here.
cat /var/log/messages | grep OOM.*ve\=(id goes here)
run this to see how many times this has happened in one day.
grep Aug\ 21.*OOM.*ve\=(id goes here) /var/log/messages | wc -l
To find script memory usage run the following lines
for each in `ls -A /var/cpanel/users | fgrep -v "."`; do grep -R memory_limit /home/$each/public_html/ >> /root/temp.txt; done cat /root/temp.txt | grep ini_set
mbstring
Check if it is installed with the following
php -i | grep --color mbstring
if that come back with this it is installed but not enabled:
mbstring mbstring extension makes use of "streamable kanji code filter and converter", which is distributed under the GNU Lesser General Public License version 2.1. mbstring.detect_order => no value => no value mbstring.encoding_translation => Off => Off mbstring.func_overload => 0 => 0 mbstring.http_input => pass => pass mbstring.http_output => pass => pass mbstring.internal_encoding => no value => no value mbstring.language => neutral => neutral mbstring.strict_detection => Off => Off mbstring.substitute_character => no value => no value
Go into the php.ini and un-comment these lines.
vim /usr/local/lib/php.ini
and un-comment these lines.

MS SQL on a cpanel box
To install MS SQL Do the following.
Install unixODBC:
cd /usr/src wget http://www.unixodbc.org/unixODBC-2.3.0.tar.gz tar -zxf unixODBC-2.3.0.tar.gz cd unixODBC-2.3.0 ./configure -prefix=/usr/local -enable-gui=no make install
Install FreeTDS:
cd /usr/src/ wget ftp://ftp.ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-stable.tgz tar -zxf freetds-stable.tgz cd freetds-* ./configure -with-tdsver=8.0 -with-unixODBC=/usr/local make install ldconfig
Tell EasyApache we want MSSQL support:
echo '--with-mssql' >> /var/cpanel/easy/apache/rawopts/all_php5
Now, recompile PHP/Apache through EasyApache. It’s OK to use the same options as previous, because MSSQL isn’t an option in EasyApache that can be toggled on and off; we did it manually (and permanently) in the last step.
Verify your work by checking phpinfo() for the mssql section.
MR Radar
Install mr radar
lpyum install mm3k-client-pull
NGINX
ADD VHOST To add a vhost you must go to:
cd /etc/nginx/vhosts/
The copy an already existing domain vhost file over to the name that you need.

my guide to openssl this will unpackage global sign certs that look like this CEDS1008174562.pfx
openssl pkcs12 -in CEDS1008174562.pfx -out cert -nodes
of course replace the "CEDS1008174562.pfx" with your .pfx files name and change "cert" to what ever you want the output file called,
also at this point you will need to enter the password that you setup when you converted the cert.

SPAM filtering fix
Make spamassassin learn spam Firstly you will have to have the customer put all of their spam in a folder, I use LWSPAM. After that has been completed you will have to figure out what cpanel users this has to be done for. Then you will ne to swithch to those users at the CLI.
su (cpanel username here)
After logging into the user you will then run the following command on that LWSPAM folder you had the customer add.
/usr/bin/sa-learn --spam /home/(username)/mail/cur/.LWSPAM/*
This has been completed tell the cusromer hola.
SPAMD
SPAMD failing
/scripts/perlinstaller Digest::SHA1 /scripts/perlinstaller --force Mail::SpamAssassin /etc/rc.d/init.d/exim restart /scripts/restartsrv spamd

1) cd to the users public_html then move the contents forward
mv (current installation)/* /home/user/public_html/
now edit the wp-config.php and add the following lines..
define('WP_HOME','http://domain.com');
define('WP_SITEURL','http://domain.com');
Then login to their whm and go into WHM and then find the database, and modify the site url to the correct domain. (located under the wp-options table as the siteurl description)
Then if the urls need stuffs removed do the following.
mysqldump dbname > dbname.sql cp dbname.sql dbname.sql.bak
Then we will have to run a sed statement to change the links to the new url.
sed -i 's/old url/newurl/g' dbname.sql
Then you have to re-import the .sql
mysql dbname < dbname.sql
should be done now.
YUM problems
First off always check this location
ls -lah /etc/yum.repos.d
And if it lists anything MORE than the following please mv everything else out of this folder.
root@host [/usr/local/cpanel/logs/easy/apache]# ls -lah /etc/yum.repos.d total 20K drwxr-xr-x 2 root root 4.0K Nov 14 19:08 ./ drwxr-xr-x 63 root root 12K Nov 14 20:02 ../ -rw-r--r-- 1 systuser systuser 660 Mar 2 2005 yum.system.repo
if you see anything more than this please move all other repos out of this folder and try again. If you problem still occurs please proceed on. Next check you yum.conf to make sure it is correct should look like the following.
[root@Shooltz.net [~]$ cat /etc/yum.conf [main] cachedir=/var/cache/yum debuglevel=2 logfile=/var/log/yum.log pkgpolicy=newest distroverpkg=centos-release tolerant=1 exactarch=1 retries=20 obsoletes=1 gpgcheck=1 exclude=apache* bind-chroot centos-yumconf courier* dovecot* exim* httpd* mod_ssl* mysql* nsd* perl* php* proftpd* pure-ftpd* ruby* spamassassin* squirrelmail*
If you yum.conf does not look lik ethat please back it up and replace it with what follows.
mv /etc/yum.conf /etc/yum.conf.bak echo -e "[main]\ncachedir=/var/cache/yum\ndebuglevel=2\nlogfile=/var/log/yum.log\npkgpolicy=newest\ndistroverpkg=centos-release\ntolerant=1\nexactarch=1\nretries=20\nobsoletes=1\ngpgcheck=1\nexclude=apache* bind-chroot centos-yumconf courier* dovecot* exim* httpd* mod_ssl* mysql* nsd* perl* php* proftpd* pure-ftpd* ruby* spamassassin* squirrelmail*" > /etc/yum.conf
After this has been completed, and if it is still broken we will reset the rpm databases.
rm -f /var/lib/rpm/__db* rpm -vv --rebuilddb
