Red Hat :: Duplicating A RHEL 5.1 32bit Server On RHEL 5.4 64 Bit
Dec 9, 2009
I have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.
I have 4 partitions in my system, out of which two(sda1, sda2) have windows on them. I have installed RHEL 4 32 - bit on sda3 and after that , installed installed RHEL 64-bit on to a partition sda 5. Now i am unable to boot into RHEL 32-bit. The error i am getting is Error 13: Invalid or unsupported executable format.
I have running 32bit Tomcat on 64bit Redhat machine. What is the maximum Xms Heapsize for 32bit applikation working in 64bit environment. Code: -Xms2048M -Xmx3300M Today I saw that my Tomcat swapping. Seems to bee problem with memory.
is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.
I have RHEL 3 and Win XP Installed in my P.C?I want to uninstall RHEL 3 and install RHEL 9 without affecting XP.how can i do this and also where can i download free RHEL 9 version or any other latest linux distribution for free?
A client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.
This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.
Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.
I am trying to download RHEL 5.4 AS version for testing..But under [URL] There is no specific link for AS version or ES version..How can I detect which iso is for AS and which one for ES..? There are separate links for AS and ES version for RHEL 4.x version but why is it not available for RHEL 5.x versions?
Environment:RHEL 5.2 and 5.4 AP x86_64, 2 drives (sda, sdb), installing without optional features like clustering and virtualization. I have tried this for a couple of days now and just can't get it to work. My goal is to take the RHEL 5.2 DVD and RHEL 5.4 DVD and install them on separate drives of the same machine. I want the grub menu to give me a choice. I prefer to understand the steps and choices offered me by the install dialog to do this rather than fiddle with grub.conf. If that is not possible, I will write up the bug.
So far, I just get the the error 13 when trying to start the grub added second OS. I have read elsewhere that "Anaconda frequently recognizes the other operating system and sets up grub so you can boot from either operating system". That would be nice. The install dialog lets me choose a drive to install to. I have figured out that I need to check "review and modify partitioning layout" to enter the advanced grub choices. Do I have it install a boot loader for the 1st OS? Trying to add the 1st OS during the second OS install creates a grub conf with no kernel line in the added boot stanza.
I have seen and tried a lot of web information about issues with VNC and the RHEL 5.x implementation of VNC.
I can't seem to get the behavior I want. Let me explain.
With SLES 10, I can use YaST and with a few clicks end up with a system that when rebooted, accepts VNC viewer connections to :1 and displays the system login screen.
Here I can log in as root or any user. Once logged in, I can choose to use the command line to restart the system if necessary and eventually, I can reconnect with the vncviewer to the system login screen.
RHEL 5.2 has a "share your desktop" setting in preferences which works fine, but requires that I be logged in locally, which prevents remote restarts. There is also a system services dialog that refuses to start vncserver as a service. There are numerous tutorial in the RH knowledge base and the web that explain how to specifically setup individual displays, :1, :2 for specific users and claim that it can work after boot. I have not been able to get these working, but what I really want is a simpler, single display, :1, that will present the RHEL login screen so I can log in as any user I want. I am the only person accessing these servers and they are behind a firewall using secure protocols when remote.
I think Red Hat did not want to make this too easy as VNC users need to consider the security risks. Is there a way to get the SLES 10 VNC approach to work on RHEL 5?
I have a situation where I want to install various versions of RHEL on removable drive. My first option was a flash drive or an external USB hard disk, but its speed is too slow.Now I have been assigned a task to search for more options about this requirement. If anybody has experience in installing the same, then please share with me.
When I submit a job via lpr on RHEL 5 using lpr -P MYPRINTER filename and then do a lpstat -t, the actual file name is not listed...just a job identifier e.g MYPRINTER-8 On AIX the lpstat command shows the actual print file name Using -C, -J or -T options in lpr also makes no difference to waht is seen in lpstat
I can logon to computer with username/passwd from AD.
But if I try to use ssh, is doesn't work
When I try to connect to the same computer using kerberos I receive this messages:
ssh -vv server.domain.com .... debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: gssapi-with-mic debug2: we sent a gssapi-with-mic packet, wait for reply
and it tries to use publickey and finally, user/pass.
What do I've have do for using ssh and kerberos? I use samba for joining computer to AD. I tried it in ubuntu 8.04 and likewise-open and it works, but not in RH-Samba.
I downloaded the demo for RHEL Server 6. I'd like to get Xwindows going, but have been thwarted thus far. edit /etc/inittab file and change the value from 3 to 5. That didnt' work. There's an X11 directory with a file called 'prefdm' that has a bunch of code in it that I have no idea what it means. how to get X windows to start?
My current project environment setup is having a single server, running on RHEL 5.2, that is constantly receiving incoming data (video and text) over a periodic interval e.g. every 30 minutes. Initial in-house testing projected the server will be generally busy, so we decided to incorporate a second server for load balancing purposes. So now, server A and B will need to be clustered. Once that is done, incoming data will balance out between the two server (or at least that is what I will like to achieve. Note, I'm aware that at the switch side, I'll need to do some additional configuration and that part is covered).
I've been reading on Red Hat Cluster Suite and the Linux Virtual Server (LVS) seems the way to go. However, I noted that the LVS solution require at least a two-tier solution, and that would incur 3 additional servers instead of just 1. So here's my questions:- I looked around and probably know the answer, but I'm gonna ask anyway. Is there a one-tier solution for LVS i.e. have anyone tried or whether it's even feasible. From my reading, it don't seem so but just want another opinion. Is there any other way for me to do the clustering (for load-balancing) without LVS?
Sidenote: I'm currently looking at Ultra Monkey and will be trying out in a while. However, the project I'm doing would be rolled out to live site eventually, and my customer is kind of....particular. I'm just wondering if there's a software/application (that need to be purchased) and comes with support.
I have been tasked with taking over the new RHEL 5.6 server our company installed. Currently we have a network printer, for general purposes let's say it's called printer1 with ip address of 184.108.40.206.I want to add this printer to the RHEL server, do I simply run:lpadmin -p printer1 220.127.116.11
Friends i got an opertunity to configure ddns in my office.I already configured staic dns in linux, but this is the first time iam configuring ddns.I just configured ddns in rhel 5.2 in my office.So far every thing working fine,dhcp is giving ip address to the clients and both forward and reverse dns database is updating.
1) In windows we can use flushdns and registerdns commands to update the dns database, like this any command is in linux to update client details in dns database?
2)how to restrict multiple client entries keeping in dhcp database.
3)if i change client hostname it is not updating the dns database,it is keeping the old one.
I have installed RHEL 5.1 in VMWare 6 I want to configure one RHEL Server with DNS & DHCP Also I would like to PXE boot, whenever I create a new VMWare Client(RHEL), the installation should be initiated via network boot
