You can add a second virtual interface (sometimes called an “alias”) to the primary network interface. This is configured, like all network interface settings   in /etc/network/interfaces    file.

The  file looks like -
———————————————–
debian:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address x.x.x.x
gateway x.x.x.x
netmask y.y.y.y
—————————————-

A simple example, assuming your primary network interface is eth0 and has an ip of 192.168.1.1 and need to add secondary ip  192.168.1.5  , then edit /etc/network/interfaces  file as below -

debian:~#  nano -w /etc/network/interfaces

————————————–
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0
gateway 192.168.1.254

#secondary ips

auto eth0:0
iface eth0:0 inet static
address 192.168.1.5
netmask 255.255.255.0
—————————————

Then of course restart networking and verify…

/etc/init.d/networking restart

and check
ifconfig -a

That’s it !

Before proceed,  First we will need to download conversion tool  and you can download it from here ::

DOWNLOAD HERE

STEPS TO FOLLOW ::
1) Download and extract the version URL (from above) that you wish to use. (wget and tar xzf)

2) Create import and export directories for the tool to use. (mkdir import export)

3) Copy your cPanel user backups into the import directory.

4) Edit defaults.conf to match the DA server you will be restoring to. The only fields you must change are the IP and name server fields. The tool will not work if you fail to do this!

5) Execute perl da.cpanel.import.pl and follow the on-screen instructions (which will duplicate the steps here to a degree).

6) After the tool is finished converting (or as it completes each individual user), move your new DA user backups from the export directory to any DA /home/RESELLER/user_backups directory*

7) Restore the DA user backups in DA’s reseller-level Manage User Backups tool.

You are done now

If you have any difficulties, please email me here :: arun@24×7servermanagement.net

Response: 530 Valid hostname is expected.
Error: Could not connect to server

Reason

When you set up name-based FTP services IIS7 wants the sitename defined with the username so that IIS7 can associate the username with the site they wish to log in to.

If you are having more than one FTP site on your VPS you will need to access FTP via following method.

Host: Mydomain.com
User: Mydomain.com|Username

Note the “|” that seperates the Sitename and the Username.

OR you remove the “Host Name” defined in the “Bindings” property of the FTP site.

When you attempt to run Regsvr32.exe to register a 32-bit dynamic-link library (DLL) on a 64-bit version of Windows via command prompt, you may receive certain error messages, This behavior occurs because the Regsvr32.exe file in the System32 folder is a 64-bit version. When you run Regsvr32 to register a DLL, you are using the 64-bit version by default.

So what you need to do is either move the DLL file into C:\Windows\syswow64  then change the path to C:\Windows\syswow64 folder and run the following command

regsvr32.exe filename.dll

OR

run Regsvr32.exe from the %SystemRoot%\Syswow64 folder.  For example, type the following commands to register the DLL:

cd \windows\syswow64

regsvr32 c:\filename.dll

Any of the above methods can work for you, Just make sure you are using the correct regsvr32 file from the specified location. Once again The Syswow64 folder contains the 32-bit versions of Windows program files and DLLs.

1.      Open a command prompt window and type start inetmgr to open the Internet Information Services (IIS) MMC snap-in.

2.      In the left pane, expand the node with the computer’s name, then expand the Web Sites node, and then select the Default Web Site.

3.      Double-click Handler mappings in the Features View.

4.      In the list of application mappings, verify that the .svc file is mapped to the aspnet_isapi.dll. If the file has not been mapped:

1. Click Add Managed Handler.

2. Type *.svc into the Request path:.

3. Type System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 into the Type textbox.

4. Type svc-Integrated into the Name: textbox.

5. Click OK.

6. Click Add Script Map.

7. Type *.svc into the Request path:.

8. Type %SystemRoot%\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll into the Executable: text box.

9. Type svc-ISAPI-2.0 into the Name: text box.

10. Using the Move Up/Move Down controls, ensure that the managed handler (svc-Integrated) appears before the aspnet_isapi (svc-ISAPI-2.0) handler in the list.

11. Click OK.

Here is what you need to do, Find out the correct php.ini configuration file.

root@server [/usr]# php -i | grep php.ini

Configuration File (php.ini) Path => /usr/local/lib
Loaded Configuration File => /usr/local/lib/php.ini

Edit the loaded php.ini file and check for post_max_size variable value, Set it to 8M which is best recommended.

root@server [/usr]# grep post_max /usr/local/lib/php.ini

post_max_size = 8M

Then restart apache, That should resolve the problem.

1.) wget -q -O – http://www.atomicorp.com/installers/atomic.sh | sh

2.)  To upgrade:

yum –enablerepo=atomic-testing upgrade mysql

Thats it,  And if you simply want to upgrade php run “yum upgrade php”

With the above methods mysql will be upgraded to latest release without any problems.

Login as root:
# cd /usr/local/src
# wget http://stderr.net/apache/rpaf/download/mod_rpaf-0.6.tar.gz
# tar xvzf mod_rpaf-0.6.tar.gz
# cd mod_rpaf-0.6
# /usr/local/apache/bin/apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c

2. Doing so will install the module into the Apache module directory.

Then Go to your  Web Host Manager (WHM) follow the tree here:
Main >> Service Configuration >> Apache Configuration > Include Editor > Pre Main Include and Select the apache version that is running on your cPanel server. and then add following code section there, and replace (place your ips here without the brakets) with the list of IP addresses on your Cpanel server:

==================================================
LoadModule rpaf_module modules/mod_rpaf-2.0.so

RPAFenable On
# Enable reverse proxy add forward

RPAFproxy_ips 127.0.0.1  (place all your ips here without the brakets)

RPAFsethostname On
# let rpaf update vhost settings allowing to have
# the same hostnames as in the “actual” configuration for the
# forwarding apache installation

RPAFheader X-Real-IP
# Allows you to change which header we have mod_rpaf looking for
# when trying to find the ip the that is forwarding our requests
===================================================

3. Once this is completed – we are ready to move Apache to another port. To move the apache to another port follow the below:

Go to your WHM  >> “tweak settings”  and change the apache port from 80 to 81 (find 0.0.0.0:80 and change it to 0.0.0.0.:81)

4. Do the following

# /usr/local/cpanel/whostmgr/bin/whostmgr2 –updatetweaksettings

5. Check your “/usr/local/apache/conf/httpd.conf”  for any occurrences of port 80,
#  vi /usr/local/apache/conf/httpd.conf

Find for port 80 if you found any occurrences of port 80 then rebuild your apache configuration file by running
# /scripts/rebuildhttpdconf   and make sure your httpd.conf file is up to date

6. Then run
# /etc/init.d/httpd restart

7. Now install Nginx. You must install pcre library in order to install Nginx on your cPanel server:

# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.9.tar.gz
# tar xvzf pcre-7.9.tar.gz
# cd pcre-7.9
# ./configure
# make
# make install

Now Install Nginx

#wget http://sysoev.ru/nginx/nginx-0.7.63.tar.gz
# tar xvzf nginx-0.7.63.tar.gz
# cd nginx-0.7.63
# ./configure
# make
# make install

9. Create nginx.sh file and put the below code section to the file :

# vi  nginx.sh
===================================================================
#!/bin/sh

cat > “/usr/local/nginx/conf/nginx.conf” <<EOF

done
done
===================================================================================

8. Save the file and change the permision and then run :
# chmod 755 nginx.sh
# sh nginx.sh

9. Now Check the  Nginx configuration
#/usr/local/nginx/sbin/nginx -t

=============================
Great install instructions, everything worked fine just some additional info if you get error like  invalid event type “rtsig” when you run this commmand: # /usr/local/nginx/sbin/nginx -t

To correct this error you should do this: vi /usr/local/nginx/conf/nginx.conf
Find line 11 and change “rtsig” to “epoll” .

This error occures in case your server is using kernel 2.4.x
===============================

10. Restart Nginx
# /usr/local/nginx/sbin/nginx

11. create init script

# vi /etc/init.d/nginx
And put the below code section to the file:
========================================================================
#!/bin/sh
#
# nginx – this script starts and stops the nginx daemin
# Taken from http://www.hikaro.com
# chkconfig:   – 85 15

========================================================================================

11. save the code and execute
# chmod +x /etc/init.d/nginx

12. make it start when the server run
# /sbin/chkconfig nginx on

13.You can run following command to check if its running:

# service nginx start
# service nginx stop
# service nginx restart
# service nginx reload
# service nginx configtest
# service nginx status

14. To Create an automatic virtualhost entry in nginx virtualhost configuration  (/usr/local/nginx/conf/vhost.conf)  when cPanel account get created on the server follow the below instructions:

Go to the cPanel script that is :

# vi /scripts/postwwwacct
# chmod 755 /scripts/postwwwacct
and put the same code that is used in “nginx.sh” in the step 9 and it will create an virtualhost entry to the nginx.

15.To remove virtualhost entry from nginx virtualhost configuration (/usr/local/nginx/conf/vhost.conf)  when cPanel account get terminated from the server follow the below instructions:

Go to the cPanel script that is :

# vi /scripts/postwkillacct
# chmod 755 /scripts/postwkillacct

and put the same code that is used in “nginx.sh” in the step 9 and it will create an virtualhost entry to the nginx.

DONE!! Cheers!!!!

“Warning: The domain is still suspended for the following reason: Domain is temporarily suspended for backing up or restoring”

Though it appear to be backup issue but backups were not running for the domain making it quite confusing, So we had the following method to unsuspend the domain.

Login into shell and ran the following command.

/usr/local/psa/bin/domain -u domain.com -status enabled

Segmentation fault

Voila !! So here is the problem plesk binaries is showing segmentation fault so it appears that the plesk upgrade didn’t go properly.  Plesk itself work on these binaries which here appears to be a problem.  Now Login into plesk and under “Updates ” select the plesk base package option and re-install the Plesk Base packages to make the plesk binaries working again.  You should receive a email when the updates are completed.

Follow the steps to reconfigure the domain in plesk database.

Reconfigure Domain:

/usr/local/psa/admin/sbin/websrvmng –reconfigure-vhost –vhost-name=domain.com

Change the status for domain

/usr/local/psa/bin/domain -u domain.com -status enabled

You should get a message the Object successfully enabled, Thats it the domain should be unsuspended in Plesk.
