View 5 RepliesI 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 can not get the node or cloud controllers to startup using the init.d scripts. I have a fresh install of CentOS 5.4 with Eucalyptus 1.6.2 I have compiled Eucalyptus and all packages using the RPM supplied from Eucalyptus and utilizing yum installer. I do not currently have any processes or applications listening currently on the ports on the boxes as well. I think it may be a permissions issue or something because I get a "permission denied error", but I am not sure if it is Eucalyptus or CentOS. It looks as if it is not binding to the address on the interface of the NIC. It may be something else however. I have the Node controller, Cloud controller, and Cluster controller on seperate physical boxes. When I try to run either the cloud controller or the node controller I get this message:
Cloud Controller:
[root@cluster-cont ~]# /etc/init.d/eucalyptus-cc start
Starting Eucalyptus cluster controller: (13)Permission denied: make_sock: could not bind to address [::]:8774
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:8774
[code]...
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.
View 1 Replies View RelatedI 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.

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.
First time setting up Ubuntu Cloud system.
I get error during install when searching for and trying to add node from the Cloud Controler: New node found on 192.168.1.182:add it? [Yn] y Connecting to 127.0.0:8774...failed: Connection refused. Error: you need to be on the CC host and the CC needs to be running.
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?
differences between Ubuntu Cloud and other virtualisation systems such as VMWare ESXi, and why one would be used in preference to another?

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?
View 4 Replies View Relatedwhat 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 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?
View 3 Replies View RelatedI 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!

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.

I have been messing around with a template from Dreamweaver and went and uploaded it to my web server last night to see if it worked. the template works when i view it both on Dreamweaver and locally through windows explorer but when i visit go to the actual website either on the same network or elsewhere it shows up but is missing the background image.
my skills in html and css are good enough to try and troubleshoot this if it were a problem with the source code but as i have come up empty handed i believe it to be a problem with the server. mind you i could have missed something, if i did please let me know so i can smack my self in the head.

View 6 Replies View RelatedI am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.
I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.
