Ubuntu Servers :: Setup My Own Mini-cloud Storage System?
Jan 26, 2010
I have collected a number of computers over the years, and now I would like to put them to good use. I considered UEC, but many do not support hardware virtualization and all I really need is storage. Over all the machines, I estimate that I have 4-5 terabytes of storage, all going to waste because each one has relatively low storage space. Is there any way I could setup a redundant storage solution that utilities these machines in a networked system?

I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.
how both storage devices will be supported by Ubuntu or Debian??
- SATA-Controller: AMD SP5100
- SAS-Controller: LSI 1068E

what kind of network between cloud controller and nodes, is required for a proper cloud installation? I mean, Does all machines needs to be in same network, in same lan, or may be in MAN or WAN ? how much should be network throughput? 1Mbit/sec , 10Mbit per sec, or 1Gbit/sec? I ask because I need to know the possibility of running nodes on different locations.

In our school I was thinking of moving to virtual desktops for the students, that would revert to a pure state upon every log out. No changes preserved after a session. We use Google docs for office, so that works. But where can we store stuff like Inkscape drawings?As far as I can tell Google storage can't be reliably mounted yet on Ubuntufor a good cloud storage option that we can quickly log into that will give us a folder for storage online?

I hope this post is in the right area of the forum.I am searching for the right operating system and application(s) to build a cloud data storage server business like Backblaze.Backblaze uses Debian but uses their own custom application to manage the data, uploads, accounts, encryption, etc... So my real question here is: does anyone have any recommendations for existing application(s) I could use on top of Debian to handle this stuff?

I have read just about every page about the UEC project, and I now know everything about it, except... WHAT IT DOES! I can't seem to find a coherent example of what it does. To the best of my understanding, it runs a virtual machine across multiple servers. Allowing the VM to use the RAM, CPU, and HDD resourced on all servers involved.

So best if you take a quick look at this image, which describes a network topology: [URL]
I am behind a firewall in the university dorm and many ports are banned. Well pretty much everything besides 80, 8080, 110, 21, 22 and the most basic ones. So I'd like to get around that.
I have a home server that is connected and reachable on the internet. So if you type in 90.90.90.90:80 into a browser it's reachable.
The task would be to set up a port forwarding or how you call it in a way that if I access my home server from the dorm or anywhere, it would act as a forwarder and forward that packet or connection to the 80.80.80.80 server on a specific port, say 2083 so that I can even access my hosting Co's admin user interface.
To sum it up: I'd like to access the 80.80.80.80 server from the dorm on port 2083 which is blocked by a firewall, but I have a home server that is reachable on non blocked ports. The home server has no ports blocked.

What's the difference in terms of scalability? We would be hosting videos and FOSS collaboration tools (wiki, forums, etc.) on 4 separate servers. If I install the cloud server, I will need to install the GUI anyways. The servers are all brand new
- 2x Intel Xeon quad cores 2.4 GHz
- 12 GB DDR3 RAM
- 4 Ethernet ports
What benefits would cloud server provide over desktop and vice versa?

I have multiple video streaming servers(Red5 running on machines internally on LAN. For different subdomains.Ubuntu 10.04 The front end to the is apache2 on a Bastion Host. To be able to reach the streaming server I embed a javascript in HTML pages as follows
Code:
<embed .....
var="rtmp://site1.my_domain.com"
>
[code]....
how will I make sure this rtmp request is mapped to a port different than 1935 as there are three other streaming servers which are also to respond to their respective requests.

what cloud computing is and i think it can help me with some of my clients i want to switch my clients from a normal ubuntu server to a ubuntu cloud. as of right now i have to send out a bill to them and if they dont pay i have to shut down there service till they pay. what i would like to do is to have a cloud where i can sell them based on what they use not a set price like it is now. and have them be able to pay there bill on the cloud and if they miss the bill then the cloud can shut off there service till its payed.
i dont know if this is possible and i have looked everywhere and all i can find is info on other businesses billing and now how to set up a cloud to do this. i wish there was some kind of tutorial for this. if anyone can direct me to some good notes/tutorials that would be very helpful. this could be a big changing point in my business if i can do this. it would save a lot of time and cash.

I downloaded the latest 10.4 server CD with the intention of running a small Ubuntu Enterprise Cloud. I am following the directions here: [URL] Ive got 2 laptops that are capable of the tasks assigned to them. Both have dual core Intel chips that are VT enabled, 4GB of RAM, 250GB hard drives. Ill use one ( "server" ) as the front end server running cc, clc, walrus and sc.The other one ( "node1" ) will be the only node controller on my little network. Ive also got another laptop as a client, running euca commands to make instances and what not.These three laptops are connected to a switch. server is 192.168.1.100, node1 is going to be 192.168.1.110, the client laptop is 192.168.1.120.
the server seems to install fine, I select Install Ubuntu Enterprise Cloud, use it as the Cluster, give the cluster a name and 10 IPs to assign, 192.168.1.150-192.168.1.160 After the server is done installing and reboots, I boot the node machine off the CD and again select Ubuntu Enterprise Cloud. It's at this point the install craps out, because it does not recognize a cloud computer on the network.
Indeed, as I go to the server I run
Code:
ps -aux | grep euca
and see nothing running. So I start the eucalyptus service, and run
Code:
sudo euca_conf --list-clusters
and nothing shows up. Ive done some googling, ran some more euca_conf commands, registering the cluster, enabling walrus, cloud and sc. I can access the web gui on the client laptop, then restart the node install on the node laptop. This time it does see the server as a cluster controller, but when it tries to fetch the preseed file, it seems to not know the cluster's IP, as the red box that complains about the lack of a preseed file lists the URL as [URL] ( or whatever the file is called, I dont have the error in front of me. )

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I am having a few websites running in a Reverse Proxy scenario on Ubuntu Server 10.04. The configuration is like this:
Code:
|--------------192.168.1.1
| (site1.abc.com)
|
|--------------192.168.1.2
| (site2.abc.com)
|
|
|
|
|--------------192.168.1.3
| (site3.abc.com)
|
|
|
|
|--------------192.168.1.4
| (site4.abc.com)
(Public IP ) |
A-------------------|
(reverse proxy server) |
(192.168.1.25) |
|--------------192.168.1.5
| (site5.abc.com)
|
Except one all websites are running properly and being redirected to their respective domains.
Following is the configuration which I used for each site define on server A a vhost file which contains following
Code:
# ProxyPass / http://<Ip of Server>
# ProxyPassReverse / http://<Ip of Server>
So if I have 5 websites then I have 5 vhost file on the gateway in above diagram A and in each of those file as above root of site is redirected to internal IP. 4 of them are running properly. The fifth website is running on port 8080:/keyword. So in its vhost file on gateway I defined
Code:
# ProxyPass / http://<Ip of Server>:8080/keyword
# ProxyPassReverse / http://<Ip of Server>:8080/keyword
I can see on Lan http://<Ip of Server>:8080/keyword but when from internet I try to see:
http://site5.abc.com
I get redirected to a page is https://site5.abc.com:8443/ and it says
Code:
The webpage at https://site5.abc.com:8443/ might be temporarily down or it may have moved permanently to a new web address. The site5.abc.com has a requirement to be run at port 8080 internally and it is not a Ubuntu server.(Red Hat based server). While rest all are Ubuntu servers including gateway A.

I am a novice in the world of cloud and recently managed to configure Ubuntu 9.04 Cloud (using kvm, eucalyptus and other packages) successfully at my college for my project work. The problem is that i can only manage to view the running instance using rdesktop from any remote machine. Is there any way to do this other than rdesktop/logs? Secondly, I want to develop a application on the lines of google docs as a part of my project. Is it possible to install apache server on this virtual instance, and host a website? How will the client access this website? Which frameworks would be required or do I have to develop one?

I'm a newbie on Ubuntu, I have a problem with squid proxy. I'd like to configure a system, include:
- a server is named ProxyServer that is installed Squid proxy.
- three servers, are named FTPServer01, FTPServer02, FTPServer03. each server is installed vsftpd.
- Clients are installed Filezilla to up/download resource.
All servers are managed by IP address. When a client request a resource, client connect to ProxyServer, this ProxyServer will switch to one of Ftp servers. I do not know how to configure the squid's config file to setup them.

I am in the process of setting up a couple of virtual servers in a cloud environment. I am currently working on my application server (Server 1) and am stuck on the creation of my ruleset for this server.
I need to allow SSH, FTP, HTTP, HTTPS, and PING on this server. This server will also need to be able to talk with a couple of database servers as well as a memcache server (all internally within my cloud environment)
I have been reading on iptables, since I have never messed with them before, and have come up with the ruleset I will paste below. I have taken other steps to secure my server...changing ssh port, not allowing root to login via ssh without logging in as a user, turning off unnecessary daemons, editing my hosts allow/deny files, just to name a few.
I am a newbie to iptables, so I would love a bit of helpful advice, criticism, and even a good explanation why I should add or remove or edit something. I really want to know the how AND the why!

I bought my wife an HP Mini [URL].. and want to get Ubuntu Netbook running on it. It comes with Windows 7 Starter, which we want to retain because Netflix won't run with Linux (gives you some BS error about "your browser is compatible, but your OS isn't"). So, I'd like to dual boot.
My desktop right now runs Kubuntu, and then I can boot in XP using VirtualBox OSE. Owing to the fact that the netbook is down on power relative to my desktop, doesn't seem like a good idea on the netbook, hence dual boot. I've seen a lot of "help, I just screwed this up!" threads, and since HP wasn't kind enough to send along a disc with Windows 7 on it, I need to get this right the first time. So, I'm going to post what I'm planning to do, let me know if I'm going to mess this up. I've compiled the below looking through a bunch of previous threads.
1) Defrag Windows drive
2) Use Windows 7 software to shrink the Windows partition
2b) Do NOT create a new partition using Windows software, just keep it unallocated
3) Boot off of USB key with Ubuntu in it, select unallocated space for install
Questions:
1) When I boot the computer up, I should get a GRUB screen asking which OS I want to boot into, correct?
2) I'm downloading 11.04 right now...anything to watch out for?
3) I couldn't find an install file for Ubuntu Netbook, do I make that selection during the install?

I just want to ask if anyone knows how to setup SAN storage on Red Hat Enterprise. I am quite familiar on doing this in AIX with IBM DS8000 but not sure on how to do in RH. Does RHE have volume management the same as AIX or do you need to install a third party Veritas Volume Manager. I know you will ask me to search in google but I am writing so that I will be pointed to the right direction.

I have a Fedora NAS (not built by me) there is a 1 Tera of storage 2x 500 set at raid 0. The server runs Fedora 7/8 I believe which, runs flawlessly. Sadly, I am running out of storage space and would like to add more. Can I just put another drive in the box? If so, what do I need to do and what impact does it have on the existing raid 0 setup. Ideally I would like to put two additional in but I am not confident how to configure them. Is this just a case of mapping them in Windows 7.

how Apache + Ubuntu + Cloud computing works together.Right now, I have [url].... set up to go from my DNS to the cloud server. httpd.conf currently looks like this:
Code:
NameVirtualHost 173.203.100.72:80
<VirtualHost *:80>[code]...
But when you go to 'elliesdev.com' it shows you the EHCP page. I have followed this thread to uninstall EHCP as well as deleting the index.php and its image files from /var/www but I still see the "default web site page" by EHCP. So I'm pretty sure its something with Apache that is causing the site to display that page? What should I do to get ride of it the EHCP default page?I also have a magento ecommerce running at elliesdev.com/magento and I would like to have Apache display it as the default page that you see when you go to elliesdev.com. I have tried changing the DocumentRoot in Apache to /var/www/magento but it makes magento display wrong. How do I make Apache referre to /var/ww/magento as the default for elliesdev.com without displaying wrong?Also, when you go to elliesdev.com/magento, the URL will turn into IP-ADDRESS/magento. How do you make Apache keep my domain name in the URL and not change it to my IP address?I have a feeling that what I am doing is correct, but there is some config file from EHCP that I have not deleted yet that is causing all of this.
