Cpanel account Migration using Scripts

First you have to create a file containing the usernames of the accounts in the old server(users.txt).
================================
Take Backup(script.sh)

for i in `cat /home/users.txt`;
do /scripts/pkgacct $i;
done
================================
To move backup

scp cpmove-*.tar.gz root@IP(New server):/home/

passwd:
================================
rm -rf cpmove-*

=================================
In new Server:

restore Backup

for i in `cat /home/user.txt`;
do /scripts/restorepkg $i;
done

-================================
rm -rf cpmove-*

Install APC on CentOS 5

APC (Alternative PHP Cache) is a free and open cache for PHP. It’s a free framework for caching and optimizing PHP intermediate code.
In other words, it could improve your php website performance

Here are some instructions on how install APC on CentOS 5 :

yum install php-pear php-devel httpd-devel pcre-devel apr-devel

pecl install apc

Create the file : /etc/php.d/apc.ini

extension = apc.so
apc.enabled=1
apc.shm_segments=3
apc.optimization=0
apc.shm_size=128
apc.ttl=7200
apc.user_ttl=7200
apc.num_files_hint=1024
apc.mmap_file_mask=/tmp/apc.XXXXXX
apc.enable_cli=1
apc.slam_defense=Off
apc.cache_by_default=1

Then restart Apache:
service httpd restart


Upon receving errors :

Fix : yum install pcre-devel


Now to see if it is really working, create a file info.php in your DocumentRoot.

<?php
phpinfo();
?>

Start your browser and go to your.server.xx/info.php.
You’ll see something like this:

Installation of Cpremote

cPremote is a remote incremental backup and it will use cPanel modules itself for taking backups to your remote backup server over ssh.

A growing number of clients are choosing to use CP Remote backup script as a ‘low load’ alternative to the standard Cpanel FTP backups. CP Remote is much more cost effective than the other backup solution we offer (R1 Soft) although it is a ‘time stamped’ solution and not a continuous data protection solution.

If you are happy to have off server backups taken nightly at a pre-defined time (usually 1am) then this backup solution could be for you. Quickly have your data restored to any cpanel server in the event of data loss.

It uses Rsync which means it is a very efficient way of working. Your first backup will take the longest as it copies all files from your server to the backup space you buy from us. The second backup only backs up what has changed so it is a very efficient solution in terms of bandwidth. All your data is backed up with this solution including Public_html folder, My SQL databases as well as email folders.

The Cpanel plug in works perfectly and allows you to check your backups and also restore quickly and easily from within an easy to use web based interface.

» Requirements:
You need a Linux cPanel server running latest stable release of cPanel(11.32 or higher) .

Need cpphp /var/cpanel/3rdparty/bin/php

» Install cPremote
Download the tar file cpremote.X.Y.tar.gz from https://portal.syslint.com/downloads.php where X.Y is the latest version.
tar -xzf cpremote.X.Y.tar.gz
# cd cpremote/
# ./install.sh

Installing Ngnix on Cpanel

Nginx can be used to serve static pages on a server running cPanel with Apache. Apache will handle the dynamic content for PHP and cgi scripts, while nginx will handle the static pages such as .htm and .html

Install nginx

 1. Make a copy of your httpd.conf file 

     cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bak

 2. Go to WHM > Tweak Settings and change the Apache port:

    The port on which Apache listens for HTTP connections. Specifying a specific IP will prevent   Apache from listening on all other IPs. (default: 0.0.0.0:80)  To:  0.0.0.0:8081 

     Do not change the https port listed.

     Click the “Save” button.

3. Grab a copy of the nginx installation script:

     mkdir /root/cpacct && cd /root/cpacct

     cd /usr/local/src

     wget http://nginxcp.com/latest/nginxadmin.tar 

     tar xf nginxadmin.tar

     cd publicnginx

    ./nginxinstaller install

 If you receive this error when trying to install:

  access key doesn't exist create it in WHM

  Then go to WHM > Cluster/Remote Access > Setup Remote Access Key and click on the “Generate      New Key” button.

  At that point, then re-run “./nginxinstaller install” command.

4. Rebuild Apache and then restart nginx and Apache

    /scripts/rebuildhttpdconf

    /etc/init.d/nginx restart

    /etc/init.d/httpd restart

Now, your static pages should be serving from nginx, while PHP and cgi ones should be serving from Apache. Both httpd and nginx processes will be running on the machine.

Please note that sites will still show up on port 80 in a browser (so you don’t have to worry that pages in a browser will require a different port). nginx works as a proxy on port 80, so it handles the incoming requests on that port to see if they are dynamic or static, then it hands off the dynamic pages to Apache (running on port 8081). Your site visitors will have no idea that Apache is running on a different port due to the proxying nginx performs on the machine for it.

Uninstall nginx

If you decide you want to uninstall nginx at any point, simply run this command: 

/root/cpacct/publicnginx/nginxinstaller uninstall

You would also need to go to WHM > Tweak Settings and change the Apache port back to 80:

The port on which Apache listens for HTTP connections. Specifying a specific IP will prevent Apache from listening on all other IPs. (default: 0.0.0.0:80)  To: 0.0.0.0:80

Then “Save” that area. Finally, rebuild and restart Apache:

  /scripts/rebuildhttpdconf

  /etc/init.d/httpd restart
