ZFS And Creating A Zpool With Multiple Servers Running Local Zpools
Jul 24, 2008
Over ethernet, maybe using iSCSI? Couldn't one machine have all the other machines mounted on it as another device via iSCSI and then add them to its local zpool? Is there a better way of doing this, where one machine isn't such a bottle neck, assuming that this can be done at all? I hope this makes sense..
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'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?
My main website is a dating/magazine/community site.
I use server ONE for as my main server for:
nameserver mail apache - php mysql
This server uses FreeBSD with CPanel/WHM Server ONE load averages are about 1-1.5
A year ago I got another server (server TWO) to host a php chat script, and unload the main server. This server hasn't a domain attached to it and I'm using it through its IP.
This server runs: apache - php mysql
And it also uses FreeBSD but with Webmin.
The load averages for Server TWO are about 0.20.
Recently I transfered all the images of Server ONE to server TWO, with a good result for loads on server ONE.
What I want to doSome users of the site complain that they can't see any images of the site due to IP based images src.
So I want to set up a redirection so images.example.com to redirect transparently to the other server.
When I tried to setup a subdomain redirection through Cpanel, I just got again the IP of the other server.
Who can this be done?
If I must setup DNS stuff in server TWO, in order to achive it, can I use it also as spare nameservers for the domains hosted on Server ONE?
What else is easy to transfer to server TWO in order to unload server ONE?
I will have two servers (both centos), one is web server, the other one is database server. I would like to set the db server (mysql server) not accessed by the public internet, but web server only through an internal IP, like 10.x.x.x
How may I set them up? I'd appreciate a step by step tutorial. Because I am not a master of linux admin.
im looking to add failover protection at my main server, in order that if it goes offline, all the traffic can be in a automatic way redirect to a failover / backup server.
For the failover server i was looking to buy a low-cost dedicated server located in other datacenter and have my dns be run at this failover server, but now i have been looking at Cloud Hosting, like Amazon or Mosso CloudServers and as it seems a very stable network, im thinking if it will be best to have setup/running my DNS at a Cloud Host...
So what do you think it would be best:
Option A: 1 main server 1 failover dedicated server 1 cloud (amazon/mosso) virtual server to run DNS
or
Option B: 1 main server 1 failover dedicated server (running the DNS)
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?
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.
I have a firebox firewall and two servers. I don't one machine to see the other one the network. The servers are for two different clients. However I would like to be able to access a backup folder on Server 2 from Server 1. What is the best setup for this?

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 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.
