How to setup Linode Server running CentOS 7 for cPanel installation..

Linode & cPanel documentation provided excellent documentation, however there was some confusion for me, so I documented my process. I’ve built several Lindoe’s, all using CentOS 6 or CentOS 7 for cPanel installations. I’ve fine tuned my process along with Linode & cPanel’s documentation. It should take roughly half an hour (30 minutes) to complete the following steps with roughly 3.5 hours for cPanel to download and install. Setting up cPanel on Linode Server with CentOS 6.2 or 7 takes roughly 4 hours to set-up.

First you must purchase, build & provision the linode using CentOS 6.2

Total ETA to complete steps: 4.5 hours

• steps 1-6 = 5 minutes
• steps 7 = 20 minutes
• steps 8 = 1 minute
• steps 9 = x minutes
• steps 10-13 = 5 minutes
• steps 14 = 3.5 hours
• steps 15 = 20 minutes

step 1.) Order your linode.
step 2.) Chose geographic location for new linode.
step 3.) Build linode (centos 6.2):
step 4.) Boot linode

step 5.) Configure CentOS 6.2 (ETA to complete= 2 minutes)
There are a couple of procedures necessary for this step..

Connect your Linode with Putty (or use the console inside Linode Manager) to set the host name & update hosts file. The hostname should be unique, in this example, I’ll use a planetary name “pluto”.

• step 5a.) set the *hostname

# echo “HOSTNAME=hname” >> /etc/sysconfig/network
# hostname “pluto”

• step 5b.) update /etc/hosts file.

Linux Server default text editor is nano, use the command # nano /etc/hosts to save/exit press Ctlr-x

By default, Linode /etc/hosts file contains two rows of redundant localhost information.. Just delete & have match the following example bellow.

default /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

example /etc/hosts
# 127.0.0.1 localhost.localdomain localhost
# 196.69.101.111 myhostname.mydomain.com myhostname

step 6.) Update time zone (ETA to complete= 1 minutes)
# timedatectl set-timezone ‘America/Mexico_City’

step 7.) Update CentOS (ETA to download/update = roughly 20+ minutes)
# yum update

step 8.) Check that the current date did not revert after update.. (if reverted repeat step 6)
# date

SECURE YOUR LINODE

step 9.) Automatic Security Updates
# yum-cron

step 10.) Configure /etc/fstab for cPanel’s disk sizes to display correctly. (ETA to complete= 1 minutes)
# nano /etc/fstab

enter the following
# /dev/xvda / ext3 noatime,usrquota,grpquota,errors=remount-ro 0 1
to save/exit press Ctlr-x

step 11.) Be sure to disable SELinux security features. (ETA to complete= 1 minutes)
# nano /etc/selinux/config
SELINUX=disabled

step 12.) Only SSH, Yum & Perl should be installed. (ETA to complete= 2 minutes)
To view a list of groups installed:
# yum grouplist

Installed Groups:
E-mail server
Console internet tools
Graphical Administration Tools
Hardware monitoring utilities
Legacy UNIX compatibility
Networking Tools
Perl Support

In this sample, I need to remove E-mail server.
# yum groupremove “E-mail server”

*If you don’t see Perl Support or if you want to confirm perl installation, type the following commands..
# which perl
# perl -v

step 13.) Deactivate default firewall (ETA to complete= 1 minutes)

# service iptables save
# service iptables stop
# chkconfig iptables off

step 14.) Install cPanel (ETA to download/install = roughly 3.5 hours)

# cd /home
# wget -N http://httpupdate.cpanel.net/latest
# sh latest

step 15.) Virus scan (ETA to complete= 20 minutes)

It’s best practice to check your system for any vulnerabilities after you install applications and modules as you customize your web server.  You can find documentation on cPanel’s website for this.

Final step, configure cPanel for your purposes..

Internal Server Error 500
No response from subprocess (php) with exit signal: 127
cpsrvd/11.35.0.4 Server at myhost.name.com

This issue can be fixed by logging into your server and running the bellow command through Putty

/scripts/check_cpanel_rpms –fix

Access your WHM and navigate to your EasyApache.
Home >> Software >> EasyApache (Apache Update).

First, begin by selecting a profile to load.
Previously Saved Config (**DEFAULT**)
! This option loads the last saved configuration. If the configuration is missing, then default values will be provided.
Continue through the build process, until you reach the Exhaustive Options List section. When you reach the Exhaustive Options List, rebuild with PDO & PDO_MYSQL enabled. With PHP 5.3, PDO & PDO_MYSQL options are available, however by default they are disabled.

Prior to using cPanel, I attempted to install PDO & PDO_MYSQL via command and have spent a considerable amount of time installing with no prevail.. Using cPanel, it took me 2 minutes with EasyApache rebuilding in the background for about 12 minutes.

If your not using cPanel and have SSH access, then use command lines to install PDO & PDO_MYSQL.

Bellow, are a couple of suggested methods..

First,
Use PUTTY look up PHP version in order to determine suggested install.

[~]# php -v
PHP 5.3.17 (cli) (built: Oct 15 2012 22:06:55)
Copyright (c) 1997-2012 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies

According to source: http://www.webhostingtalk.com/showthread.php?t=1119422
Run the following command:

[~]# yum install php-pdo
This command resolved the forum post above, however I was unable to install.

Then I came across a blog ‘ForLinux’, offering instructions on how to install PDO & PDO_MYSQL using PECL: http://www.forlinux.co.uk/expertise/blog/2012/07/30/installing-pdo-and-pdo_mysql-extensions-on-cpanel-server/

I opened my PUTTY and followed instructions to no prevail.

As suggested by website ehow.com, I used the command# –enable-pdo
No prevail..

Conclusion,
Using cPanel saved me tremendous amount of time, as I would be on an expedition looking to resolve a simple task..
