XEN: Create Debian 4 DomU On Top Of Centos 5.2 Dom0
Dec 16, 2008
I'm not a Debian user, so I want some advice how to install Debian 4 as guest OS on top of Centos 5.2 dom0.
Mostly on Google, there's a manual on Centos on top of Debian. I've tried to use the netinstall iso for debian and mount it on /var/www/html/debian and use it for remote install source. So far don't have any success on that.
I will be dropping my shared-hosting plan and ordering a small VPS as soon as I can decide on which operating sytem to use. It seems that most companies offer the following choices: Suse, Debian, Fedora and CentOS.
I freely admit that I am a full-fledged n00b when it comes to linux and will be learning as I go, the problem is I just don't know where to start because I'm not familiar with any of them. I have at least heard of Suse, Debian and Fedora before, but didn't even know this CentOS existed until yesterday... and yet, it seems to be one of the more popular choices.
So I was wondering if some of you seasoned VPS veterans here could recommend an OS, tell me what the differences are, or otherwise share any experience you might have with any of them.
I am attempting to migrate from a debian os server with the latest plesk 12 to Centos (rather cloudlinux) and would like to know if there are any options that should not be checked during the process?
I recently tried to do the normal procedure, which is to transfer all objects, etc. And for some reason the percentage went from 1-50% to then back to zero.. but when clicking to check the current status, its still working
Status: in progress Current operation deploying domain.com current operation progress: empty bar
Different sites are transferring, but I am not sure if the migration will effect the system because the difference in OS folder structure and file location.
For some reason I am having issues with latest Plesk with php and wordpress. HTML sites are fine, but all php and wordpress sites are giving a 502 error after fully migrating. I repaired with Webserver Configurations Troubleshooter and rebooted and its still giving me the same issue.Also, noticed my previous server had php 5.4.36, the new CentOS server has 5.4.37.
I've been running 3 Xen servers for the last few months in a production environment, and facing a strange problem with one of them.
Server 1 and 2 run a couple of DomU's and are running just fine.
Server 3 runs one DomU and takes care of all the backups for the DomU's of Server 1 and 2 The DomU on Server 3 is crashing every night, right when the backups are being made. DomU becomes inaccessible, but keeps appearing at xm list with state ------
When I try to connect to the console it wont let me connect. The only way to get the DomU back up is by using xm destroy and xm create again.
For the back-up I use NFS where the DomU on Server 3 is the host, and the other DomU's of Server 1 and 2 connect to it through an internal bridge.
Below you'll find some information about Server 3:
Hardware: HP ProLiant DL380 G5 10Gb Memory ( 8 x 146G SAS10k in RAID 5 )
"Create a zend id for your machine." This is apparently for them to create a product key for their software and have to bind to it?!
I have never heard of this and have been unable to locate any information on it.
This is a Centos box with php 5.2.5 installed: Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies with Zend Optimizer v3.3.0, Copyright (c) 1998-2007, by Zend Technologies
I want to backup a entire folder thats in / not in any other folders.
I've tried this command but I get the error described below..
tar cvpzf opensim.tgz
tar: Cowardly refusing to create an empty archive Try `tar --help' or `tar --usage' for more information.
The folder is called opensim. I was logged into SSH with root access and tried the command directly, not going into other folders because well I dont want to, I wanna backup that 1st opensim folder that I can see on the FTP also.
I'm having some trouble finding a VPS host that offers Debian and Plesk. I've searched the forum but nothing's really panned out. I'm currently with Geekstorage but the server has been slow (same problem reported by others).
Anyone have recommendations for Debian + Plesk VPS host?
NX server needs ssh and some libraries to run. These packages are normally not installed during the basic installation process.Use the following comamnd to install
#aptitude libstdc++2.10-glibc2.2 ssh
Install Free NX Server in Debian Etch
First you need to download the .deb packages using the follwoing commands i did the three steps..
Now you need to install .deb packages in the following order this is very important
#dpkg -i nxclient_2.1.0-17_i386.deb
#dpkg -i nxnode_2.1.0-22_i386.deb
#dpkg -i nxserver_2.1.0-22_i386.deb
If you get any errors use the following comamnd to fix
#apt-get -f install
Now you need to make sure ssh and nx servers are running if not start with the following commands
#/etc/init.d/nxserver start -------------------- but the problem is i cannot connect to the nx . i installed the program on windows but what is the username and password should i use? i tried to use the root but it said that the user root cannot be used.
From some weeks I try to have a secure install for my Debian. THis server will be a shared hosting host so need special security but I don't know how to do this.
My requirement are :
- PHP (mod, not cgi)
Actually, users can navigate into my server by using phpshell script. And someone put lots of file into /tmp directory so I tri to secure all of that but don't find good tuto for that; do you know where can i have some?
And what about php using cron so execute with php-cli how to secure it?
I've just ordered a dedicated server with Ubuntu server, but they've come back to me to say that they've had trouble installing Ubuntu server on these particular servers.
As an alternative, they're offering to install Debian. My concern is that I come from a windows background and have spent the last month reading and playing with Ubuntu Server in vmware. I'll be running a small handful of sites on the server and will rely on the apt-get and package installer in webmin to get things set up and for administration. I'll dabble in the shell a little, but only when needed.
Should I go with a different host that can offer Ubuntu, or will I be okay with Debian?
I am on a vps server and want to install a GUI based control panel. ISPconfig being the most talked about however i am unable to find a tutorial which helps you with step by step installation on debian 4;
problem on one server with debian, the last month it have a 100% f uptime, but since yesterday automaticly it reboot every 1 hour exactly!
this is a game server , dont have service like httpd , mysql dns , nothing! , I uninstall cron jobs thinking that will solve the problem, but no .....
I install firewall, run rkhunter and chkrootkit, check whell gruop and nothing
Jan 17 05:20:00 debian -- MARK -- Jan 17 05:40:00 debian -- MARK -- Jan 17 06:00:18 debian syslogd 1.4.1#18: restart. Jan 17 06:00:18 debian kernel: klogd 1.4.1#18, log source = /proc/kmsg started. Jan 17 06:00:18 debian kernel: Bootdata ok (command line is root=/dev/sda1 ro )
I change root password and ssh port but nothing... I think that could be a issue on debian or some exploit cause it, this was happend Suddenly one day to another it is very Strange....
I just upgraded to Debian from RedHat, but I'm a little lost trying to get phpMyAdmin working. Below is a snapshot of my config.
I'm sure I'm missing something.
looks like I have the packages...
