Creating VPS Partitions On Dedicated Server For My Own Use
Apr 26, 2009
more experience Linux users to partition my dedi into VPS. I have an Intel Quadcore 2.4 Ghz, 500GB HDD, 2GB DDR RAM, dedicated server with a max 100mbit connection and 2000GB BW/mo. It has Centos 5.3 (centos-release-5-3.el5.centos.1) installed on the server and I want to install the DirectAdmin CP soon.
I'm not a reseller or webhost and don't intend to become one. This server is for my exclusive use.
I want to use half the server to run virtual instances of a Windows 2008 server and a KDE or similar Linux virtual desktop using FreeNX as well as a 4PSA VoIP Now or similar software. The other half of the drive will be to run my businesses websites, mailserver, a DNS server, etc.
I have six IP addresses for this server that can be used to this end and will host at least three websites (under separate domain names) and one or two blogs for which I will install requisite software.
I understand that the RHEL 5 embedded virtualization software will allow me to partition the server into VPS for various purposes.
Here are the outputs from ckdisk -l and parted -l respectively for the current HDD partitions.

For the DA install, so I don't have to try to figure out where things are, I'd like to use their more complex partition structure as follows:
/boot 40 meg
swap 2 x memory
/tmp 1 Gig. Highly recommended to mount /tmp with noexec,nosuid in /etc/fstab
/ 6-10 Gig
/usr 5-12 gig. Just DA data, source code, frontpage.
/home rest of drive. Roughly 80% for user data. Mount with nosuid in /etc/fstab if possible.
I will install dovecot to be able to create SSL access to my webmail so don't need a '/var' directory.
What I want to know is:
1) Should install virtualization and partition the drive prior to having DA installed?
2) How do I best partition the drive into VPSes so I can run distinctly different virtual instances of different OS and/or programs on the VPS as well as use half for websites, blogs, servers, etc.?
3) What else do I have to keep in mind when doing this?
I'd appreciate any positive, useful response and information on getting this done and I'd like to try to get this done by Monday or Tuesday of next week so DA can be installed on the appropriate partition.
I've added a new Apache/MySQL node to our PPA cluster and we'd like to be able to host a single subscription on that node for the Apache webhosting and MySQL databases for that subscription while allowing that subscription to utilized the rest of the shared resources in the cluster, such as mail, DNS, etc. I'm looking for the best way to go about doing that.
I guess one simple way would be to set the new server to 'ready to provide' and set the rest to not ready, add the "linux shared hosting" hosting subscription to the customer account, then switch the new server to not ready and the rest back to ready. That works fine I suppose in a small cluster, but there has to be a better way. Is there a way to craft a service template that restricts subscribers to a particular node for Apache + MySQL and leaves them to rest of the "regular" nodes in the cluster for other services?
I've created many vpn connections in the past using private ip addresses allocated automatically but I haven't really found much on making a vpn server that hands out a dedicated ip address.
The problem: Basically, I have Windows Server 2003 x64 Enterprise and an extra public IP address that is unblocked from the internet. I have a private server (Windows Server 2003 Enterprise R2 i386) sitting here at home that is behind many firewalls (both my isp and my own) that controls my x10 light system, etc.
I have custom written software so that within my home network, I can goto my server's IP address via a web browser and http address and bring up a control panel that controls my lights, etc. Everything works great, but when I'm on my mobile phone, I cannot access this nice control panel because it is on the internet outside of my home network.
I am wondering if there is a way to configure my public web server to act as a VPN server, accept public requests from this IP address and forward them onto my private home server that would have a vpn established 24x7. I haven't found much documentation on doing this, and I'm not entirely sure what to search for.
I have a Vista machine. I have installed CentOS 5.1 by selecting the C: (Active partition) and formatting it as ext3 partition. Then after installation, in the Hardware > Hard disks, it is showing only one NTFS partition. But actually I have 4 NTFS partitions. When I try to mount that partition using ntfs-3g, I am getting "/dev/sda3: permission denied" error.
We're outgrowing our current bulk storage system and I'd like to solicit opinions.
With 2 TB disks and a 16 disk array, it's possible to have a single 28 TB volume (after deducting RAID5 parity overhead and a hot-spare disk). I've seen arrays from Aberdeen with 48 and 96 disks, for nearly 200 TB. Windows supports up to 256 TB per volume when 64K cluster sizes are used.
Our backup system uses a ton of storage space, and it would be far more convenient, and more efficient from a utilization standpoint, to access that space as a single volume.
Breaking it up into smaller chunks, such as 2 TB each, means we have to make a "best guess" on balancing actual need.
For example, if we assign 25 servers to each 2 TB volume for backup storage purposes, some volumes might only see 800 GB of consumption (remaining 1.2 TB allocated but not used) while other volumes might get 1.6 TB used (remaining 400 GB allocated but not used). Key concept: wasted space, because we have to over-estimate need to assure adequate headroom.
From the opposite viewpoint, if we had a sudden increase in need that exceeded the available space allocated to that volume, we'd have to move that server to a different volume. Key concept: increased admin workload to monitor and re-balance distribution as needed.
Now if we used one giant volume, there would be no guesswork, no "allocating more than we think is needed" for a bunch of small volumes. All servers share one huge common pot.
But there has to be a practical limit from a system-overhead standpoint. Our backup sets consist of a few multi-gigabyte files, so using 64K clusters will not cause much waste from slack space.
I'd like to get your opinions on maximum disk volume sizes from a practical standpoint.
Is it possible to specify where your CPanel user's data is stored?
Let's say I have four hard drives without RAID, I have hard drive one on /home, hard drive two on /home2, hard drive three on /home3, and so on. Is it possible to setup users on the different partitions to spread out disk usage?
To explain further, I would like to set it so maybe one reseller account was using /home2, then another was using /home4, and another using /home.
Any ideas on how to go about splitting up user's data across seperate partitions?
I have an AMD Athlon 1.2MHz with 512MB of RAM. I would like to change this computer into a server where to host my websites. However I do not have any experiance on what web hosting includes.
I am definitly going to use tomcat or jetty as application server. Would it be enough this computer? could I just upgrade it? would the people comming on my website experiance a very slow loading?
I have been using IMAP for the last few years, but I find it difficult to retain my carefully built set of filters across PC and laptop changes.
Is there a way to set filters at the server level so that they work at all times whether I am using Webmail (Horde or SquirrelMail) or a PC or a laptop? Kind of a set once and forget it thing?
I can see the email filtering option in each domain's cPanel, but I am not too sure it's the most robust option.
I have two servers, a plesk 11 installation and a plesk 12. Running Centos.
On the plesk 11, set up by others, I have a nameserver running NS1.xxxx.net & ns2.xxxx.net point to the IP of the server.
I want to create a nameserver on the plesk 12 -- can't see how to do this. Is there a nameserver setup function in plesk 12?
More advanced question:
The domain name xxx.net is hosted at 1&1 where I have put the IP of the plesk 11 server in the A records for ns1.xxxx.net and ns2.xxxx.net. I have pointed ns3.xxxx.net and ns4.xxx.net at the IP of the Plesk 12 server -- as I would like to use these addresses for consistency. If necessary, I'll use ns1/ns2.yyyy.net.
I have recently opened up a game, in which is slowly becoming pretty active. However, I want the ability to create an IRC server - locally. We are currently only on shared hosting, because we don't have a lot of bandwidth usage yet - however I believe it would be successfull to start an IRC server now, plus it would be nice to know how to do it.
However, I have two questions/problems: I am not interested in having another computer run the IRC server, because I don't have a stable internet connection except at home in which Im not willing to have to drive from campus to home if something were to happen. Therefore, I'd like to be able to run it off a PC I have ideling inside my dorm. The problem is, my roommate uses it a lot while I use my laptop, and therefore it needs to run off Windows, or somehow give me the ability to run it off a linux while running Windows - or something silly like that.
Therefore, I have two possibilities. Either one, this is completely not possible or two there is some sort of emulator or something like in which I can run IRC on Windows - Or the ability to create an IRC server directly onto windows.
Any ideas? If it is the second possibility, please provide some good tutorials or software into creating a basic IRC server. I don't really care about security unless it is going to affect the connection/box. It's not like we have a bunch of hackers who are going to attemp to exploit it, because when we launch out of BETA we will buy a server, in which we will have IRC installed onto it.
On my VPS SUPHP with PHP 5.2.9 and MySQL 5.0.77 is running absolutely fine.
Suddenly without making any change on the server today i got a 500 internal server error. I don't think there is any permission problem.
Now i change the PHP5 Handler to "cgi" so everything is normal but if i change that to suphp then showing "500 internal server error" anyone can tell the reason of the problem.... Apache suexec is "on" but off also doesn't make any change?
There is any cache/temp file folder for suphp which is filled or some other problem?
Where i seem to be having trouble is that i have allways used Reseller accounts to run my business. But recently this month i have purchased My own Servers. I currently Own 9 Servers in total. So when it comes to Actual Server Managment im running into a brick wall lol
One of my business's invlolves Free web hosting. And and I have been using one server for the free web hosting clients.
The problem is that sigle server is Maxed out I cannot add any more accounts to it withought jeperdising its stability.
This service Not only inlcudes Free domain hosting but sub domain hosting as well.
So now that you know a little background on what im doing heres the question
We use Client Exec as our billing and Auto Account Creation and we know its possible to Add multiple server to Client Exec and we can tell it to creat new accounts on anouther server But what hapends when someone wants a subdomain?
Its my understanding that subdomains can only reside on the server that the actual domain is being hosted. Is this right ? or is there a way to creat subdomains of a .com on anouther server where is not located...
Also i was wondering if it was possible to join servers together in one whm? So under Ip Adresses we could just specify a new Ip & server would this work ?
I really need help fast since i get an average of 90 sighnups a day. and im sorry if theres a simple solution to this.. Im just new to actually owning my own hardware instead of using someone elses.
to me it just doesnt make any sence and i know it needs to be possible somehow ..
I have setup Slave DNS using plesk 12. But it is not creating the zone in slave server. I could see log in /var/log/messages of slave server. But DNS zone is not creating. I have followed the KB "[URL] ...." for setup.

I am currently using a shared hosting but due to increasing traffic and server load my existing host is not able to provide reliable services and I am planning to upgrade my hosting service.
While I was searching for Dedicated Servers, I learnt about Virtual Dedicated Servers but I am not very sure about their reliability? Are Virtual Dedicated Servers useful? My website current serves over 2500-3000 visitors a day resulting in 30,000 pageviews and I am expecting the traffic to grow by atleast 2 folds in the next few months as I start some PPC campaigns and Email Marketing for my website. Can a Virtual Dedicated Server cater such needs assuming my website to be more of less dynamic website written in php?
I have Plesk 11.5 (service provider mode) on a Windows 2008 server IIS7.Most of my sites are developed in .asp and therefore i use a custom 500-100.asp error page that check s the IP of the visitor then displays either a friendly error, or if its my IP a full error of what has happened (it also emails me the error). This allows me to debug pages easily whilst developing and to keep an eye on anyone trying SQL Injection hacks on my sites (as the error and email also have session variables and IP address).I dont have root access to the server as it is a Webfusion dedicated server.I have following the Plesk documentation -
1) Switch on custom errors for the subscription 2) Look in virtual directories and navigate to error documents 3) Find the error in question (500:100) and change it to point at either a file or URL
FILE - I had the data centre add in the 500-100.asp error page in to the virtual template so that my page is available in the list of virtual files - this didn't work but that maybe because its not a static page??
URL - when i add the path it says its incorrect, if i add a fully qualified address, it accepts it but it doesn't work.give me a specific example of the URL that can be entered relative to the root as the format in the documentation isn't accepted. The last step is to restart IIS which is also an issue as i cant seem to do this from the Plesk panel..It is as if it isn't catching the 500:100 error, and only catching the general 500 error??
I am going to be buying a dedicated server from kimsufi Most likely the 2XL Package.
My streamers will be using my server aswell, On weekends we will be running 3-4 streams at a time, weekdays 1-2 at a time.
Spreading all the streams out, at anyone time we will have 300 viewers.
I need to know your advice on this before i go spending money.
How do i convert my dedi into a flash media server, i need red5 or something, thats all i know so far. My streamers wil be streaming to server with FME, And i also want it coded so that my streams can only be embedded on my site.
Basically i dont have a clue where to start, how long would it take me to set up etc....
In addition, what kind of server do i need, windows / linux / traffic / burstable / standard etc..
First thing I would like to clear off I DO NOT WANT TO MAKE VPS FOR PROFITS/BUSINESS. I need to make VPS because me and my friend have bought this server
[url]
I want to make VPS because my friend like to use Ubuntu desktop and I like to use CentOS from the OVH website they pretty much give you the basics to make VPSes so I have chosen virtuozzo
So my enquiry is
1. Can I have Ubuntu desktop and CentOS on it at the same time
2. How easy is it to create VPSes using virtuozzo since I need a GUI and ease of use
3. Also if I want can I change from CentOS to forexample Ubuntu desktop too
4. Also does anyone know and good tutorials
My main use of creating different VPS with different OS on them so I can learn there language and other stuff
When you create a SSL certificate for www.mydomain.com vs mydomain.com, is the "www" vs "non-www" decided when you generate the CSR (for example, in cpanel/whm)? Or is it "decided" when you actually purchase the certificate?
