To Create a new partition on Linux server we have to use following steps steps.

Login to your linix server with root user and Using #fdisk -l  command you can list the number of partitions already created on your linux server.

#fdisk -l

It will give you following details

Disk /dev/sda: 499.5 GB, 499558383616 bytes
255 heads, 63 sectors/track, 60734 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1         653     5245191   83  Linux
/dev/sda2             654        3713    24579450   82  Linux swap / Solaris
/dev/sda3            3714        6324    20972857+  83  Linux
/dev/sda4            6325       60734   437048325    5  Extended
/dev/sda5            6325        8935    20972826   83  Linux

If you want to create 1000MB partition which is mounted on /new directory then proceed with following steps

#fdisk /dev/sda

type n for new partiton and specify the cylender size as as +1000M then type p to view new parttion then type w for save

then run the following command

#partprobe

Now you need to format the the newly created partition

#mke2fs -j /dev/sdaX

The X is the partition number which you have created

Now create the dirctory where you want to point the newly created partition

#mkdir -p /new

then with following command you can point the new parttion to the directory.

#mount -t ext3 /dev/sdaX /new

To keep these settings permanant you need to add the entry in fstab.

#vi /etc/fstab

/dev/sdaX /new ext3 defaults 0 0

save and quite the fstab file.

You can verify the setting by rebooting your server . Please check the new partition with command

#fdisk -l

Virtuozzo vs. Hyper-V

Hyper-V and Virtuozzo are both popular VPS platforms used by a large number of web hosting providers for the provisioning of Windows VPS hosting services, with Virtuozzo being favoured for Windows Server 2003 VPS hosting and Hyper-V being the most reliable solution for Windows Server 2008 VPS hosting services. When the two virtualization platforms are compared they don’t share that much in common, with Virtuozzo being designed more or less specifically for use in web hosting whilst Hyper-V has been designed with larger corporations in mind rather than for commercial purposes. Some users may have their own preferences when it comes to which virtualization system their VPS servers are based on; however, the virtualization platform that your web hosting providers uses is unlikely to have any kind of effect on how your Windows VPS server functions.

Virtuozzo and Hyper-V both offer reliable Windows VPS servers, regardless of the Windows operating system version that you will be running, although the fact that Hyper-V is part of the operating system and isn’t a third-party application or component means that it is likely to be more reliable in certain circumstances than Virtuozzo. The main feature that differentiates the two virtualization platforms is that Virtuozzo comes with a web based interface that offers users an alternative way to manage their VPS server, and this is known as the Parallels Power Panel; although Hyper-V doesn’t come with this sort of feature as standard, web hosting providers are able to use third-party applications such as DotNetPanel (DNP) to achieve a similar system. As Hyper-V is mainly used to power Windows Server 2008 VPS servers, Hyper-V VPS hosting services are going to be slightly more expensive than Virtuozzo Windows VPS hosting services – Virtuozzo tends to be used to power Windows Server 2003 VPS servers, although it is also used for Linux VPS hosting as well.

Once you are completed with your website designing and development procedure you need to publish it on server so that your website would be accessible form any part of worldwide. If you are hosting it on windows hosting platform you have different ways using which you can publish it like … using FTP, using Plesk control File Manager and through Adobe Dreamweaver / Microsoft Frontpage software. Among these FTP is widely used by all webmasters as its easier to used as compare to other options.

Once you have completed with designing and development part and have added domain in Plesk control panel of your windows hosting account then you need to follow following procedure for publishing website.

Publishing Sites using FTP:

Once you sign up with any web hosting service provider you would get server login details using which you can connect to your hosting account.

Once all required web files and image files are uploaded under specific directory, you need to close FTP session and need to crosscheck if your website is running fine and all files and images are displayed properly.

Thus you are done with publishing your website using FTP.

If you want to change few php values for your Linux VPS web hosting server then you will have to edit /etc/php.ini file on your VPS. As a VPS server Administrator you would be having root access to your server thus you have access to php.ini file of your server. You can easily change all required PHP settings/value such as post_max_size, memory_limit, asp_tags, upload_max_filesize etc…… for your server through php.ini file.

For example : If you want to turn register_globals ON, you will need to change the line from your php.ini file. just search for register_globals = Off and change it to register_globals = On. Thus by amending your PHP.ini file you will turn ” register_globals ON ” for every domain hosted on your VPS unless a domain has a different value specified in its vhost.conf file.

How to access Awstats from outside the control panel ?

Accessing Awstats from outside the control panel is easy.

Step 1.

Download awstats from awstats.sourceforge.net

Step 2.

Uncompress awstats-5.6.tgz

Step 3.

Copy the contents of the uncompressed cgi-bin folder from your hard drive to the user cgi-bin directory (this includes awstats.pl, awstats.model.conf, and the lang, lib and plugins sub-directories).

Step 4.

If necessary (should not be needed with most setups), edit the first (top-most) line of awstats.pl file that is

#!/usr/bin/perl

to reflect the path were your Perl interpreter is installed. Default value works for most of Unix OS, but it also might be #!/usr/local/bin/perl

Step 5.

Move AWStats icon sub-directories and its content into a directory readable by your web server, for example /home/users/public_html/icons

Step 6.

Copy awstats.model.conf file into a new file named awstats.myvirtualhostname.conf.

This new file must be stored in /home/user/public_html/cgi-bin.

Step 7.

Edit this new config file with your own setup :

- Change LogFile value with full path of your web server log file (The path is: LogFile=”/usr/local/apache/domlogs/domain.com”).
- Check if LogFormat has the value “1″ (it means “NCSA apache combined/ELF/XLF log format”).
- Change DirIcons parameter to reflect relative path of icon directory. (DirIcons=”/icons”)
- Edit SiteDomain parameter with the main domain name or the intranet web server name used to reach the web site to analyze (Example: www.mydomain.com).

IMPORTANT!
- Change DirData to use the same Statics file than Cpanel Awstats and do not loose any entry.
(DirData=”/home/user/tmp/awstats/”)

Step 8.

Access AwStats by the URL:
www.domain.com/cgi-bin/awstats.pl?config=domain.com

Done!!!

The AwStats will refresh the Statics every 24 Hours.

Is it possible to allow users to update Awstats from the Cpanel?

Yes, Change the parameter “AllowToUpdateStatsFromBrowser” in /usr/local/cpanel/etc/awstats.conf set to 1,

AWStats add a button on report page to “update” statistics from a web browser. This is not a good idea, because Update process can be long so you might experience “time out” browser errors if you don’t launch AWStats enough frequently. Also, it take around 12-24 hours to take into effect.

There is an option in WHM>> Server Configuration >> Tweak Settings>>Stats and Logs to “Allow users to update Awstats from cPanel“.

How to update Awstats and webalizer via shell?

We could update the webalizer using the command /usr/local/cpanel/3rdparty/bin/english/webalizer -N 10 -D /home/username/tmp/webalizer/dns_cache.db -R 250 -p -n domain.com -o /home/username/tmp/webalizer /usr/local/apache/domlogs/domain.com

The Awstats can be updated by using the script /scripts/runweblogs accountname
