[No]

No, You don't need to install a Wordpress plugin as long as you are already using one of the pre-built CloudFlare extensions.
The CloudFlare Wordpress plugin helps get the original IP addresses from visitors commenting on your customer's site. That's done automatically in the pre-built plugins.

[Output]

You can perform the following command which checks if the file exists on the current server:

#find / -name ModCloudflare.pm

You should be able to get output like below:

Output   :   /var/cpanel/easy/apache/custom_opt_mods/Cpanel/Easy/ModCloudflare.pm

An uninstall script has been provided to unregister the plugin with cPanel and remove all CloudFlare specific files from the server to deactivate the plugin.

The following set of commands will download the necessary files, execute the uninstall script and ultimately remove the uninstall script as well

#wget https://raw.githubusercontent.com/cloudflare/CloudFlare-CPanel/master/cloudflare/installers/cloudflare.cpanelplugin && bash <(curl -s https://raw.githubusercontent.com/cloudflare/CloudFlare-CPanel/master/cloudflare/uninstall_cf) && rm -f uninstall_cf

NOTE: This will not remove zones or users from CloudFlare that have been registered through the plugin.

Run the following command on your cPanel server to update the plugin

#/usr/local/cpanel/bin/cloudflare_update.sh

Run the following command on your cPanel server to see the version of the plugin:

#cat /usr/local/cpanel/etc/cloudflare.json | grep version

[cPanel re-installation]

cPanel re-installation :

The cPanel re-installation procedure is quite similar to the cPanel installation process, but with one slight difference. Please follow the below step-by-step direction.

[1] Login to your existing cPanel server via SSH.

[2] Run the following command in SSH

# /scripts/upcp --force

[3] Please wait until the process completes.

[CSF (ConfigServer Security & Firewall)]

Occasionally you will find that you need to open up a port in your firewall for some application or another. Depending on which firewall is installed on your server, there are several ways to go about this.

CSF (ConfigServer Security & Firewall)   :   CSF can be configured in Web Host Manager (WHM) as well as over ssh.

[1] Open up the following file:                           

/etc/csf/csf.conf

[2] Add the port you mean to open to the needed line:               

# Allow incoming TCP ports
      TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,26"
      # Allow outgoing TCP ports
      TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873"    

[3] CSF then needs to be restarted for the change to take effect:

csf  -r

APF (Advanced Policy Firewall)   :   APF can only be configured by accessing the server over ssh, as the root user. Once in your server, Follow the steps below.

[1] Open the following file in your favorite text editor:

/etc/apf/conf.apf

[2] Search the following line:

# Common inbound (ingress) TCP ports
      IG_TCP_CPORTS="20,21,22,25,53,80,110,143,443,465,993,995"

[3] After saving and closing out of your text editor, you will need to restart APF. This is as simple as running:

apf -r

WHM (Web Host Manager) :

[1] Type configserver in the Find bar in the upper left hand corner.
[2] Click on ConfigServer Security&Firewall.
[3] On that page, click on the Firewall Configuration button:
[4] That page will allow you to edit the exact same file you would if you were accessing it over ssh:
[5] Like with the ssh instructions, add the necessary port to the list.
[6] Then click Change at the bottom of the page to save your changes.
[7] After that is run, you will need to restart csf. Thankfully, the very next screen you can see there is a button for that, Restart csf+lfd.

Closing ports    :   Closing ports in either firewall are as simple as removing the port from the list in the configuration file, and restarting the firewall.

[SMTP (Simple Mail Transfer Protocol)]

It is simple to enable SMTP (Simple Mail Transfer Protocol) on another port. To do this please follow the step-by-step direction below.

[1] Login to your WHM (Web Host Manager)

[2] Next Go to the "Service configuration" section

[3] Locate the row that says "Exim On Another Port" option.

[4] Please enable the following two check-boxes.
          

                Monitor = YES (Checked)
                Enabled =  YES (Checked)
               

[5] Once Done, Click on Save to apply your settings.

Now your cPanel SMTP should start working on PORT 26 rather than just on PORT 25 (Which is blocked by most of the ISP's)

Sometimes it is smart to use port 2525 as Exim alternative with hosting server cause it is really easy to remember.

[Advantages]

In my previous post's I have mentioned What is Shell script, Different types of Shell's and How to write Shell script in linux. In this post I would like to mention about the importance of Shell scripts.

Shell scripts can take input from a user or file and produces output to the screen.
   
Whenever you find yourself doing the same task over and over again you should use shell scripting, i.e. Repetitive task automation.  Shell scripting is useful for 

       [1]  Creating your own power tools/utilities.
       [2]  Automating command input or entry.
       [3]  Customizing administrative tasks.
       [4]  Creating simple applications.
       [5]  Since scripts are well tested, the chances of errors are reduced while configuring services or system administration tasks such as adding new users.

Advantages       

       [1]  Easy to use.
       [2]  Quick start, and interactive debugging.
       [3]  Time Saving.
       [4]  System Admin task automation.

Shell scripts can execute without any additional effort on nearly any modern UNIX / Linux / BSD / Mac OS X operating system as they are written an interpreted language.

Disadvantages       

       [1]  Compatibility problems between different platforms.
       [2]  Slow execution speed.
       [3]  A new process launched for almost every shell command executed.

Practical examples where shell scripting actively used       

       [1]  Monitoring your Linux system.
       [2]  Data backup and creating snapshots.
       [3]  Creating email based alert system.
       [4]  Find out what processes are eating up your system resources.
       [5]  Find out available and free memory.
       [6]  Find out all logged in users and what they are doing.
       [7]  Find out if all necessary network services are running or not. For example if web server failed then send an alert to system administrator via a pager or an email.
       [8]  Find out all failed login attempt, if login attempt are continue repeatedly from same network IP automatically block all those IPs accessing your network/service via firewall.
       [9]  User administration as per your own security policies.
     [10]  Find out information about local or remote servers.
     [11]  Configure server such as BIND (DNS server) to add zone entries.

Following steps are required to write shell script:

(1) Use any editor like vi or mcedit to write shell script.

(2) After writing shell script set execute permission for your script as follows

syntax:
chmod permission your-script-name

Examples:
$ chmod +x your-script-name
$ chmod 755 your-script-name

Note: This will set read write execute(7) permission for owner, for group and other permission is read and execute only(5).

(3) Execute your script as

Syntax:
$ bash your-script-name
$ sh your-script-name
$ ./your-script-name

Examples:
$ bash bar
$ sh bar
$ ./bar

Note: In the last syntax ./ means current directory, But only . (dot) means execute given command file in current shell without starting the new copy of shell, The syntax for . (dot) command is as follows

Syntax:
. command-name

Example:
$ . foo

Now you are ready to write first shell script that will print "Milesweb Hosting Services" on screen. See the common vi command list , if you are new to vi.

$ vi first
#
# My first shell script
#
clear
echo "Milesweb Hosting Services"

After saving the above script, you can run the script as follows:

$ ./first

This will not run script since we have not set execute permission for our script first; to do this type command

$ chmod 755 first
$ ./first

First screen will be clear, then following output will appear on screen.

Output :
Milesweb Hosting Services

[Different types of shell]

Different types of shell

A number of different shells have been developed for Unix-Like Operating System; the most popular are described here.

[1]  Bourne Shell(sh):-
        Original Shell of Unix.
        Written by Stephen Bourne at Bell Labs in 1974.
        Lacked interactivity provided by most modern shells.

[2]  C Shell(csh) :-
        provides a C-like language to write shell scripts

[3]  Korn Shell :-
        created by David korn
        Has features of C and Bourne shell along with some additional features.

[4]  TC shell (tcsh) :-
        Default shell of FreeBSD and its descendants.
        Available in the public domain.

[5]  Bourne-again shell (BASH) :-
        Default shell of Linux Operating System.
        Developed by GNU project
        It is based on Bourne shell and has features of Bourne and C shell as well

How to check Shell's available in your system ?
Quote   :   cat /etc/shells

To find your current shell type following command
Quote   :   echo $SHELL

[Shells]

Normally Shells are interactive. It means shell accept command from you (via keyboard) and execute them. But if you use command one by one (sequence of 'n' number of commands) , then you can store this sequence of command to text file and tell the shell to execute this text file instead of entering the commands.

This is know as Shell script.

Shell script defined as:
"Shell Script is series of command written in plain text file. Shell script is just like batch file in MS-DOS but have more power than the MS-DOS batch file."
