Multiple Servers
May 19, 2009
I currently have 2 web servers both running the cPanel Control Panel.
Out of the two servers only one is used and the other is just used currently to test scripts. It has come to a stage with the website capacity that I now require both servers to run in con-junction with each other to spread the load.
Questions:
1) There is a file upload service, How would you go about networking both the servers to allow remote removal / uploading of files to different servers. Eg, If user is on server 1 and files are stored on server 2. Also deletion of files etc - The website is programmed mainly in PHP.
2) File updating - The website is constantly being updated and therefore both servers will need the PHP files to be in sync. How would you go about doing this?
Both servers are at the same Data Center location.

We are looking for KVM/IP solution for multiple server. Where we can add the users remotely and give temporary access to the server owners. Once they are done we remove them from access list. So it can be used by someone else.
Anyone know for KVM/IP solution with kvm switch which can solve our purpose of KVM.

I currently have two servers, one is rhel 5 with cpanel, the other is windows 2003 with plesk 8.4
Each server wants you to setup a Hostname... one that is FQDN but not being hosted on that server so I setup a generic dns domain as follows...
SERVERCODNS.COM
Now for the hostname I setup both servers to be use this domain but different prefix... so...
SERVER1.SERVERCODNS.COM
SERVER2.SERVERCODNS.COM
Is this ok? Will I have problems?
My cpanel continues sending me emails nightly that my DNS is routing to another ip?
which bring sup my next question...
Is is ok to NS1.SERVERCODNS.COM, NS2.SERVERCODNS.COM for say the RHEL server and then DNS1.SERVERCODNS.COM and DNS2.SERVERCODNS.COM for say the windows? Is this going to cause problems?
Whats the difference or proper procedure for setting up DNS with my registrar (*ENOM) vs in the control panels they have Nameserver tools?

if it is possible to use more than 2 regular DNS entries across 2 hosts? So if a site goes down the other host picks it up?

I have a website.
I have it on 2 different servers.
This is because if the first server goes down for whatever reason, i dont want the site to go down.
To get this to work, is it just a case of adding more nameservers to the domain?...
becuase this doesnt seem to be working... the domain seems to always resolve to the server that is listed last in the list of nameservers...

Has anyway come up with a way to have several servers connected to one external CD-ROM on a USB Hub/network? This could allow a few external CD-DRIVES to handle a whole rack and the possibility of setting the bios via KVM/IP on a server to boot from CD, then it would boot from the CD tied in on the USB "network". Maybe using a USB hub? Or would this cause possible security issues having multiple servers tied in via USB ports?
I would love to have the ability to have maybe 3 or 4 CD-ROMs tied into multiple servers for OS installs remotely without having to actually go into the DC for this. You could put the CD-ROMs on your APC reboot and just turn on the one you need and set the bios to boot from CD (ie: one drive could have CentOS, one could have Windows, etc)
I'd be interested in some ways people have done this or what they use.

Does anyone know how I can run multiple servers. But still use the same Domain name.
Such as server one with ip 547.547.547.547 uses domain www,m1.domain.com
and server two has ip 547.548.548.548 but uses domain www,m2.domain.com

What is the best way to run one command on multiple servers. Security isnt too much of an issue as I'll be doing a master/slave type setup, with the master being a system in the office with no ext access.
I'm thinking pssh is going to be quick and easy, what do you use?

I have 2x servers with the following os/control panels:
1x Windows Server 2008 running Plesk 9.2
1x Centos 5.3 running cPanel/WHM
What I wish to do is to point all of my domains to the nameservers:
ns1.domain.com
ns2.domain.com
But, the domains hosted could be on either of the boxes above (because some sites are ASP.NET and others PHP).
Each of the above machines are running BIND and I have not yet setup nameservers on either of them. How should I proceed with this?
In addition (for arguments sake), if I then add additional servers how would I then achieve the same?
If there's already stuff around on the forum (I've done a search but found nothing specified to my issue of running a windows and linux box with completely different control panels) please point me in the right direction.

A website I am involved with may soon hit a problem due image uploading being stored on only one server. We are unable to find a realistic solution which would allow us to upload images from 1 central location.
The website is programmed in PHP and is on a standalone web-server - currently the images are uploaded to the same directory as the website however we are looking to move the images to another server for scalability.
Is it possible at all to upload using a directory link of some kind, eg, the directory would be /serverip/path/to/images which you would upload to? Or any other realistic approaches that you know off.

Is it possible to combine multiple servers via "Configure Cluster"? Will the hosting domains use same ns1.mydomain and ns2.mydomain.com if one server is located in UK and second is in USA Datacenter. Can somebody provide me information with explanation?

I run a vbulletin based web forum ([url] and everything is going quite smoothly. We are currently in the process of getting a partnership with a supplement store.
Basically, our goal is to have our own store for Lean Bulk, but it will be run by a different company, and will be on their server.
Soo, the store database and custom script will be staying on their server, but my forums will be staying on my server. What I want is for the store to be located at [url]or [url]
Either one works for me. However, the tech guy that runs all the stuff for the store, is trying to tell me that this is "impossible." While it might be somewhat difficult, I have a hard time believing anything is really impossible.
The tech says the only thing we can do is have the store located at:
[url]
Personally, I think this looks unprofessional, and would rather stay away from this solution.

I purchased a domain, domain.com, from GoDaddy.
I have 5 servers, 2 running CentOS and Apache, 3 running Windows Server 2003 and IIS. Each server has it's own dedicated IP address, so I can access each site by going to [url]
Would I would like to be able to do is set each of these servers up with a subdomain on my domain.com. So I would have [url]going to one server, [url]going to another server, etc.
I logged into GoDaddy's Domain Manager. However, it appears that the only form of subdomains they have is redirection. So while I can create server1.domain.com, it merely redirects to [url]
I can mask the forward, but this creates problems with the login on the servers because they use cookies. In addition, the address always appears as [url], it doesn't have the "index.html" or "/login/login.aspx" when
I click links. The actual links appear as "[url] and not "[url]
Is there anything I can do? I want the subdomains to point to a particular IP address, not redirect.

I have a server with plesk8 installed. I forsee a time when I shall need either to move to a new bigger server or to add a new bigger server to what I already have.
Problem is, my isp says that PLESK will only work on single server set-ups and can't work in a multi-server environment.

I was talking to my host the other day about configuring multiple servers as a private LAN. I was wondering if anyone has successfully set up a configuration of using separate servers for each task for shared hosting accounts. I.E. Having certain servers as web servers and others dedicated as MySQL servers, e-commerce servers, mail servers etc.
Does anyone do this? I can see it boosting performance.

I run a small hosting company and i have been using multiple (different) nameservers for different servers, for example...
Nameserver IP
ns1a.domain.com 192.168.0.1
ns2a.domain.com 192.168.0.2
ns1b.domain.com 123.123.0.1
ns2b.domain.com 123.123.0.2
How do i make it so i can have ns1.domain.com and ns2.domain.com pointing to all different my servers?

I have been trying to setup SPF records for all of our hosting servers but need some assistance.
Lets say we have three servers with the following RDNS:
ns1.server.com
ns2.server.com
ns3.server.com
Would we create one SPF for server.com and add it to the DNS zones on each server?
Or should we create a separate SPF for each server?

how to make it so if the server that hosts my website receives too much traffic it will go to a mirrored copy of my website on another server? I want to make sure that it doesn't go down in the event of a big boost in visitors.

Lets say for example I have 10 servers independent of each other. I want to be able to have only 2 Nameservers, NS1 and NS2 where all the domains should resolve to and then they should be handed off to one of the 10 servers. I dont want to have 20 Nameservers for example NS1 thru NS20 for all 10 servers. That would also be a waste of IP addresses.
I have a few murky solutions in mind. I would appreciate if someone would shed some light on the issue,

I'm planning host multiple game servers on a single machine. I'm going to configure my own machine for this purpose. I'm uncertain on how powerful should I build my machine.
I'm going to host resource demanding games like Battlefield 2 and Armed Assault. Both of the mentioned games has a dedicated server application that requires roughly 2ghz of CPU power and 1GB to 2GB of RAM (depending on connected users) to run on.
Base on the above requirements, I'm going to put together a machine with 2 dual core Opteron or Xeon running at 2ghz and 8GB of RAM. The machine is going run 4 virtual servers with the game server application running on them. My configuration uses basic division to calculated the required CPU and RAM on my custom configured machine. Is this a practical approach?
Has anyone tried anything similar with xen? I'm worry about any performance impact that might happen due to overhead or shared cpu & ram cycle latency as game server demands real time performance.
I'm though about doing this because it's cheaper to rent a 1U rack space running 4 game servers than renting 4Us for the same purpose. Care to share experience or thoughts on this subject?

I'm trying to figure out how I would host 20 or so websites using one static IP address and 2 servers, on a network behind a router.
I think I have edit the Apache config files, but that's driving me crazy. Is there any other easier way?

obviously a (relatively successful) shared host would have multiple servers hosting their different clients. But they'd usually have all their client's setting their domain's nameservers to just one set of DNS (i.e. ns1/2.hostsdomain.tld)
Would you set this up via a DNS cluster? I.e. on a cPanel/WHM following these sorts of instructions?
For some reason I never can fully get my head around DNSes, so apologies if I ask any silly questions thusly.
With the above in mind, say your billing system sets up a new client - say it sets them up on SERVER2 (the host's second server for hosting clients). The DNS records would automatically be synced to the name server, right? And then, when someone visits the client's website/domain (with nameservers ns1/2.hostsdomain.tld) the 'hops' would roughly go:
Client's domain >>
Host's name server >>
This 'forwards' the 'connection'/request to the client's website files on SERVER2
Is that about right? And if the name server and SERVER2 are hosted in physically different parts of the US (say), would this make each request slower since it involves hops to two different servers before the client's files are shown?

What's the best setup for me to have for a machine which will host web files that other servers have to read and serve to end users on the web?
For example, I have servers Web1 and Web2 serving the same content from Files1.
I assume it's best just to go with RAID 10 and be safe or?
More importantly for me, what's the best way for these systems to communicate? I.e.
what protocol should be used for the web servers to read the files from the file server?
I once used SSHFS for serving the same static files on a couple of machines from one location... but that's presumabely very slow (at the time wasn't a problem).
All systems will be running CentOS Linux.

Can the same nameservers be used on multiple servers/vps on different geographical locations and if so, how are they setup? That would save me quite some money. Hoping for some input.

I recently found out the hard way that cPanel cannot run behind firewall using NAT, I got pretty far in configuring the server but I ran into major issues when it came to SSL and gave up!
Anyway, I current have one cPanel server with CSF and IFD which is working great (I guess), but what happens when I want to move all my server over to cPanel? Will I need CSF/IFD installed on the servers? This seems really impractical and a nightmare to administer. What firewall can I use so that all my cPanel servers can sit behind it?
Any input would be much appreciated as I cannot seem to find a solution, everything seems to have a catch!

Would it be possible to split website components transparently across 2 servers and make it look like a single site? For example: run a forum on ServerA and a wiki on ServerB, but with the same base URL? Doing this will allow me to buy smaller servers instead of a single huge server.

i have the need to be able to have a monitoring software that could check and monitor the status of my diferent servers and vps hosting accounts. So when a server goes down i can have a report of wich component of the server failed, so i can identify faster, server problems.
The software sould also check the most number of server features, like:
FTP
DNS
APACHE
DOMAINS
PING
DATABASES
ETC
In a simple way, wich are the best programs to make this job done.
im willing to pay for a professional, simple, and reliable software.
