Warning Sign

When you perform a system backup from the Parallels Plesk Control Panel, then after its completion you normally go to the Backup Manager and Click to download the current backup file. But sometimes file never get downloaded and you experience a slow  server performance.

Reason

The above situation occurs  most likely due to the unavailable free disk space on one of your partitions.

Explanation

If you have a small root partition:

[root@/]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/isw_Volume0p2
9.5G 6.1G 3.0G 68% /
/dev/mapper/isw_Volume0p6
437G 51G 364G 13% /var

You may have set up backups to be stored on another partition:
Directory for storing backup files – “/var/lib/psa/dumps”
Temporary directory for dumps – “/var/tmp”

[root@/]# grep DUMP /etc/psa/psa.conf
DUMP_D /var/lib/psa/dumps
DUMP_TMP_D /var/tmp

However when you download backup files from the Plesk Control Panel, they are copied to a temporary location as a temporary file (these parameters are not manageable):
Full backups -> /usr/local/psa/PMM/tmp
Domains backups -> /usr/local/psa/tmp

Since those folders are located on the small root partition, you server runs out of free space.

Solution:

You need to create a symlink from the default location to some folder which have the enough free disk space.

For Example:

[root@ /]# ln -s /var/tmp/ /usr/local/psa/PMM/
[root@ /]# ln -s /var/plesk_temp/local-tmp /usr/local/psa/tmp
[root@ /]# chmod -R 777 /var/plesk_tmp/local-tmp

Bodhost’s Linux dedicated servers are offered with the choice of cPanel/WHM and Plesk if you require a web-based control panel through which you can manage your dedicated server and any hosting related services, for example clients and web hosting plans. As the only other method of management available to you as a Linux dedicated server administrator is through SSH, a web hosting control panel is strongly recommended as an addition to your hosting package so that you are able to fully utilize the features and power that a dedicated server can offer.

The most popular control panel for Linux servers in any case is cPanel; not only is cPanel a low cost control panel suite, but it is also uses system resources efficiently to ensure that your server remains stable, even when under load. Some of the core features of cPanel include:

• cPanel comes in two parts: the cPanel control panel is designed for end-users to manage their own shared hosting accounts and websites, whilst the WHM control panel is slightly more complicated in its features and GUI with the main aim of allowing system administrators and resellers to manage their part of the deal effectively
• Along with the previous benefit, cPanel is also available in two different packages depending on whether you are using a VPS server or a dedicated server; this is at the core of the control panel’s ability to effectively use the resources that it has available
• Full support for the management of MySQL databases is also possible through Plesk, specifically with the aid of the PHPMyAdmin database management system.

cPanel is often seen as being the most complete solution available to Linux system administrators and is the ideal platform for anyone with a Linux Dedicated Server who is looking to start their own web hosting business. Like any other web hosting control panel, cPanel offers the facilities necessary to create and maintain your own web hosting clients, based around your own web hosting plans.

We here at Bodhost can also offer you the Plesk control panel for your Linux dedicated server, but we don’t feel that this can offer you the same benefits and features as cPanel. Along with Plesk, we can provide installation services for any control panel that you wish to use on your Linux Server.

Windows Control Panels

With our Windows dedicated hosting plans, you will find that you are more limited with the choice of control panel offered by Bodhost as we only support Plesk on our Windows servers. However, you shouldn’t let this change your mind about choosing Bodhost as your Windows dedicated hosting provider because Plesk is one of the most feature-rich web hosting control panels available for the Windows platform. Some of the features offered by Plesk that you will find useful include:

• Full support is offered for the ASP.NET 4.0, the latest version of the framework, so that you and your hosting clients are able to retain full control of how the framework impacts on your hosting environment and any applications that have been developed using it
• Microsoft SQL Server and MySQL Server (for Windows) can both be integrated into Plesk so that you are able to manage the databases hosted by both applications from the control panel
• Support for various other third-party applications is also included with Plesk to aid the security of the web hosting environment through virus detection on the server and performing backups of the data hosted on a regular basis.

If there is another web hosting control panel that you would like to use with your Windows dedicated server then you should contact Bodhost’s 24×7 support team as they can offer assistance with the installation of a number of different applications; however, it should be noted that you will need to purchase and supply your own license in the case of commercial applications.

I once had the opportunity to test all control panel systems on my test VPS. So here is a brief overview of my experience just in case anyone should need a concise overview. It was based on a fresh Debian Lenny 64bit system.

SysCP: Probably the slimmest of all control panels.  I liked very well, because it is actually perfect for a VPS with a handful of domains and hardly more email addresses. But also for commercial hosting SysCP is to use; thanks to ticket system and various user levels. The installation was pretty easy, even when the manual to change the config files is a bit time consuming. However, I wanted to send the mail postfix part out not (but probably was more like gadgets than on my previous SysCP ).

Conclusion:

* Very slim and resource-efficient panel
* Relatively easy to install
* Updated user interface
* Own Apache directives conveniently controlled via the panel
* Supports many distributions
* Does not so deep into the system
* Time-consuming to change the configurations of the respective components
* Partially annoying dependencies when installing the deb package
* Configuration of nameserver manually only
* Unwieldy Prefixsystem

The control panel I liked well, but I have for my taste nearly contain enough features. I would have shut me here and there but want some more configuration options for each service. Above all, the ability to manage the DNS zones on the control panel. I would have liked. Thus the control panel offer few advantages in this respect to the work in the shell.

ispCP Omega installing was even simpler than that of SysCP, since one is the change of the individual config files could save. It is therefore commendable in my opinion could determine application trust the admin name itself, which provides a little more security. In addition, the CP brings many features such as webmail in their own design, with much more detailed statistics, that makes the resource consumption seen, which is higher than that of SysCP.

what annoyed me uttered, however, is that only by php cgi / fastcgi can integrate. That may be safer but it is much slower and thus a failure of the CP. Ensures that it is on vServer seemingly unusable. Quite often the cgi processes are not started properly terminated. So that they fall into infinite loop on, which may affect on VDS and (so is reported in various forums) and even the entire node crashes can bring.

However, this should occur only on VPS with 64-bit OS. For me, the problem then, where-upon the VDS was about the only VPS Control Panel addressed the host. Although there are many instructions all operate with mod_php but this would require after each update of the CP re-adjustment.

Summary:

* Elegant surface
* No manual adjustment of the config files needed
* Many features
* Name of the admin accounts on their own identifiable
* PHP will only fastcgi / cgi-usable
* Resource consumption partly tangible
* Bug on 64 bit systems vServer

The CP seems more likely to be somewhat larger for hosting and corresponding server. Many features and configuration options are nice for the lazy admin shell, however, impede the creation of deeper configurations, since they are overwritten by the CP again. The resource consumption was by the (almost) acceptable use and partly outside the cgi. But it should be mainly responsible for the above bug. Therefore I could not completely take the test over and “explore” all functions. Therefore it should be missing some points on the list above conclusion.

ISPConfig 3: First a little note; one must distinguish at ISPConfig 2 to 3, because both versions are not only very different from each other but with some rooms even have their own developers hanging. I opted for the version 3. The full installation, I led for a HOWTO, which set up the same time a Debian system with the general explained.

The installation should perform well from a beginner can be, but it is of advantage that is not immaculate fully in dealing with Linux to be. After installing the CP did his service at once (only with the mail server I am still having problems, again) and its many possibilities spread out before you figured out. In addition to a comprehensive monitoring site with which you deal with many logs, RAM and CPU load, view general information directly into the CP, and the CP also contains the usual admin, customer and reseller system. Additionally, the CP waits with many more features to help the one in the management of many domains, such as the Possibility of CSRs (certificate signing requests) directly generate from the CP. Your own Apache directives can include on the CP.

Conclusion:

* Functional and thanks to Ajax by far the fastest surface
* Many (in my opinion) useful features
* Own Apache directives simply include
* Allows quick access to page monitoring for various logs, etc …
* Many additional components for the monitoring of emails (ClamAV, Spamassasin, etc…)
* Own DNS zones
* No problem for managing multiple IPs
* Very helpful community (even if it comes along as a complete beginner)
* The CP is easily extensible via plug-ins
* But there is not many for version 3
* Interface only works with JavaScript
* Installation may not be suitable for beginners

So I will probably put ISPConfig 3 on my new VPS, since it is the best as compared to functionality and resource conservation. Everything depends on the sending and receiving of emails gives me a headache, but this probably is not the CP, since I use Postfix on GeneRally somewhat at odds. But I should solve the problem, this is my dream CP.

Plesk: At the end of another narrow field report with Plesk, which is to the version 9.2, a Debian-based 32-bit system where I used Plesk for almost 2 years in use, but this was not necessarily to the conviction but rather to the fact that the VPS with other CPs behaved quite bitchy.

The installation of Plesk for windows is moderately easy. You start the install script and the rest of the task makes almost by itself. Plesk was moderate at the best resource on average time consumption, the side structure of the surface was always horribly slow. For Plesk provides by far probably the most features with the average Admin access, however, it is the very low gearing. This does have a positive impact for beginners with chronic Shell-phobia, but who wants to set up a service time on the Plesk custom configuration so looks often in the tube, as Plesk’s own changes quite cheeky about writing again, and other settings not offered .

Conclusion:

* Offers many features
* Easy installation
* Very easy to use (for beginners)
* Well-functioning auto-update
* Requires many resources
* Own Apache directives can be placed manually only by Shell
* Dovetails very much with the system
* Completely overloaded interface, Which loads very slowly
* Sometimes useless features (Application Vault, etc.)
* License for the small private users priceless

So I must keep Plesk credit, as it has always worked very reliably and the auto-update feature was very convenient. However, I still cry no tears for the CP. If you wanted to just quickly change one thing this has been hampered by sometimes extremely slow-loading pages, so some options to hide in the seemingly endless icons soups such skill that one might despair.

Thus, virtually the entire Plesk server digs under the nail, preventing almost any self-employment. All in all, the value for a joke, if you are not on the mass license can call his provider.  Mostly Plesk is recommended for beginners. Thus, particularly who want to control everything rather than a graphical interface.

So that is my rundown of the most common CPs, maybe someone can take advantage of it. Please understand it is not as a professional report or test but rather as a rough overview.
