The issue is i am using the RHEL server as my webserver and database centre. Now its a brand new formatted server with good amount of RAM and the usage is not much. Its being accessed locally over the LAN. But still i can see speed deficiency. Some of the pages do not get loaded and some times i can see the delays in loading the new pages. Any idea y is it so? Or is there anything i can do to increase the speed?
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 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.
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.
What are the bare minimum configuration files that would be needed to rebuild a RHEL server?We are thinking about creating a generic base image and then just copying over the necessary files (fstab, hosts, networking, etc) to get a failed system back up and running in the least amount of time possible. I am fairly new to Linux and have suggested that we have a share on a redundant server that is /server_configs/Svr_name/*.* (names are subject to change and *.* would be all of the pertinent config files to make a fresh build customized enough to emulate the failed server).Is this even possible and/or plausible?
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 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 few doubts regarding fonts configuration in RHEL 5.4.
[vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts [vinay@linuxcoe4 fonts]$ ls 100dpi 75dpi encodings misc TTF Type1 util
Also there is no fonts.dir file, which describes fonts under a specific fonts directory in /usr/share/fonts tree. But we can find fonts.dir or fonts.scale file under /usr/share/X11/fonts/ tree. Does files under /usr/share/fonts tree are not dependent on fonts.dir ?
I have and RHEL5.4 conecceted to an SAN HSV200. When I present a LUN to it, In system-confg-lvm gui appears a device like /dev/mapth/mapth0 (that�s the correct device to multipath) and other like /dev/sda or /dev/dm-N, as uninitialized entities. How could I configure to not display this device (/dev/sda) and prevent human errors?
This is the things I need:
1- I want (if it is posible...) to disappear the part where it says "uninitialized entities"
2- Is It necesary mantain the partitioning done to default (like /dev/mapper/mpath0p1) with device-mapper-multipath (kpartx command)? or Can I delete it without future problems?
I am trying to install and configure nagios on RHEL 5. I have apache 2 installed and php all working as exepected. When i install nagios following the these steps [URL]. The nagios folder that is suppossed to be placed under apache2's httpd is no where to be seen. So when I try to open localhost/nagios/. It says: The requested URL /nagios/ was not found on this server. What can I do for the nagios to work on this system. The apache and php are working fine.
issue in starting up Open view monitoring on couple of linux servers and here is the output from mii-tool looks like.
eth0: 100 Mbit, full duplex, link ok eth1: 100 Mbit, full duplex, link ok
Based on what I understand, eth0 goes to monitoring and the other 2 ethernet cards go to FE. I am not an expert in system administration but would like to know if there is any issues with the above settings/configuration (in fact, im also looking for what do they infer and what is the settings?
One monitor is working fine but the display is not coming on other monitor. I guess no problem in monitor because I swapped the cable to check the individual monitor. When I try to install the new driver its giving GCC-VERSION-CHECK while installing. And I do not think I have to install the new driver because it has already one. What should I do to configure the dual monitor. Do I have to edit any configuration file.
My system configuration details are below. Redhat version : Redhat Enterprise Linux WS release 3 (Taroon update 4) Driver in SRBC 26: NVIDIA-LINUX-x86_64-1.0-7664-pkg2.run Nvidia card model : Quadro fx p171 Bios version of Nvidia : 18.104.22.168.07 p/n : 900-50171-0400-0000K 600-50171-0002-201J
I want to create a small network of 3-5 computers. I want to have one computer as my server and have services like NFS, DHCP, NTP, etc. I want to connect it to 2-4 other clients that have the bare minimal installation of linux on them. I would like 1 client computer to have a static ip address and I would like another to receive a dynamic ip address from the server. How would I go about doing all of this without the assistance of GUI's? I want to be able to do all this with the ks.cfg and network config files.
