Ubuntu Servers :: Enterprise Cloud Services Not Running On Boot?
May 7, 2010
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 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.
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.
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?
After upgrade of 11.1 to 11.2 I noticed that none of services that was started in 11.1 at boot are starting now in 11.2. I check run-level of services with
Code:
chkconfig --list
When I start services manually everything is OK, but on restart they do not starting. Another weired thing is that my SuSEfirewall2 is filtering everything on input, nevertheless my previous configuration is still there, but ports are closed.
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.
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.
We do have a problem on running the images on the cloud server.. how we can use or how we can run the eucalyptus cloud images using elastic fox? or there is another simple way to activate those images provided by eucaplypus... thanx in advance... and were trying to activate the private cloud only..
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
I have installed Ubuntu enterprise cloud on two machines(Cluster and node)and trying to set up an image and test my internal website in private cloud. if there is any documentation or any steps?
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.
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?
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.
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 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 got my hands on a couple old servers. An HP tc2021 and a Proliant ML110. Sure they're ancient, but I thought they would make a couple of great Ubuntu Servers for a new "start up" business I'm trying out. Now I've got to decide the best scenario to distribute the load between the two servers. I'm going to make an internal domain and will probably be running the following: Kerberos, Samba, Apache, Postfix, mysql, bind, dhcp, SVN, GCC, and Nagios. So in summary, I'll have the following roles; domain controller, web server, file server, and network monitoring services. how they would handle splitting these services up between two servers?
I recently got a second-hand ProLiant DL380 G3. Currently it has no storage on it. So I was wondering, if and how I could run Ubuntu Server 10.10 (or any free server distro really) from PXE boot until I can get a hard drive. After I get the drive I will also need to install it using PXE as well.
i know that there is already a command for it but it comes out with a lot of letters that makes it hard to find the services that are runningi'm talking about services like DNS, APACHE, DHCP, SAMBA, SSH etcis there a command that will list these services and related services that are running instead of showing a bunch of jumbled and lettered mess thats hard to comprehend
I am trying to run two different copies of vsFTPd service in the same server, one for IPv4 and the other one for IPv6. Because as I know that you cant run one vsFTPd server for IPv4 and IPv6 in the same time.
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:
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.
Should I have hal and/or dbus services running when my system doesn't have GUI? For example, in case of a mail/web server where I have console applications only on it.
I have installed release CentOS 5.5 w/ fetchmail services. I've already configured the /.fetchmailrc in the correct format that I've learned from topics and I've checked also the sedmail running status. When I invoke the #fetchmail command this often happens:
fetchmail: WARNING: : Running as root is discouraged. 2 messages for user1 at mx.mailserver.com.ca: (1 of 2) (4353 octets) .....flushed
I have configured two NIC 's One for the public IP and another for the local network, I've tried to use the two IP's in the POP3 and SMTP settings of Mozilla Thunderbird but still user1 can't get messages.
I'd like to run a Tor relay, but am trying to understand the security implications. For some time I've run my torrent client in a VirtualBox virtual machine, which is run as a very non-prived user, bridges directly to The Internets, and writes to one directory on the host. My belief is this is about as secure as it can be, but am open to suggestion.If I run a relay in the VM it wouldn't be associated with my use of Tor as a client, which is fine since there is no technical need for them to be connected and it's desirable for security.I read that chroot jails can be broken, particularly when run as root, so I don't really trust that. Also studied a vserver, but it must share the network setup which doesn't strike me as isolated enough.
I am baffled by fedora's feeble attempts to work with Samba. I have ran various versions of Fedora for the last few years, and sporadically, the Samba gui and samba itself have had such problems. My current problem in Fedora 11 (64bit) is that samba doesn't seem to be running correctly. It is allowing the hosting of shares, but it does not show that it is running in the services gui. It shows enabled, but when I attempt to change it by starting or stopping, nothing happens. The samba gui also shows that it launches but then never actually starts. I saw very similar problems with Fedora 9.
