I just installed RHEL on our in house web server. This server is going to host our secure public server.
I was wondering if installing a control panel (cPanel) would be a good idea? I would like something automated to setup php, mysql, apache etc.
As cPanel is an integral part of server hosting and has the ability of compiling Apache 1.3.x with PHP4 (cgi) and PHP5 (dso) on your server OS.
Does anyone know or have baselines/benchmarks for which performs better generally for hosting: 32bit or 64bit RedHat 5 when cPanel 11 has compiled for the Apache and php mentioned above on either of these OS editions? (assume latest versions of apache/php4/5)
I was wondering if 32bit performed better or 64bit on a quad core Xeon. Don't forget PHP is compiled for prefork and not multi-threading for Apache 1.3.41 (which are considered legacy 32bit forked apps compiled against 64bit OS).
Or rephrased, could i be hampering performance by running it on a 64bit OS on a Xeon (X3210) or improving performance? I'd assume 64bit would offer better all round processing power, or is this a misconception.
I recently decided to get a server on RedHat Enterprise 5 X86_64 (64bit), when i wondered if 32bit version would have provided better performance and been the better options for compatibility.
I have a problem with time at one RHEL 4 server, it is a plain box, and from time to time the time (hours) seems to be auto modified, no one is touching the box and then from once it got modified to a few hours less than what we specified, to change time and date we always use:
Code:
date --set "2007-10-24 13:35"
hwclock --set --date="2007-10-24 13:35"
The only thing that I noted is that ntpd daemon was running, while in the rest of our plain box it is not running, maybe this is the reason the system is auto chaning the time?
For the past two weeks, our Hypertown RedHat RHEL 5.2 server has been going down everyday because of a wierd Kernel Panic problem.
Attached you can see what was displayed on the console at the time of the panic. This is what SoftLayer tech. support team was able to obtain from the console.
We are not using Samba or NFS-based applications.
Here is the server's info:

Will you use RHEL 4 or 5? Is there any great differences between them?
I want to use the newer version, but helix server [url] requires RHEL 4 to run, so I am just thinking whether I should use RHEL 4 or 5.
When will RHEL 5 final be released? (And Centos 5 as well)
Wasn't it supposed to be released in December?
Going to order a new server fairly soon, and I'm facing the tough question if I should go with 64-bit or stay with the "classic" 32 bits. My operating system of choice is Red Hat Enterprise 4.
From the research I've done, RHEL 4 (64 bits) should come with dual libraries that would allow running 32 bit and 64 bit applications under the same 64 bit operating system. Sounds great, and if it comes with an overall performance boost I am all for it.
But I've also heard that that's only the theory - in reality, I could end up banging my head against the screen for uncounted hours because compatibility still isn't as good as it's supposed to be. I don't plan to run Plesk or Cpanel, but I still don't want to get into hot water with other applications I've been using on my current 32-bit server.
All in all it's intimidated me quite a bit, so I'd probably go with 32 bits this time around, just to be on the safe side. Then again, I'm still having an eye on the possible performance boost, so dunno. Does anyone have an idea what's the latest on this? 64 bit already safe for the non-experimental-minded, or bleeding edge and stay away from?
Anyone out there have experience with SuSE over RedHat? RHEL is obviously the generalized Enterprise version used across most commercial hosting companies, but I'm interested in hearing about some SuSE experiences people have had.
It looks like SoftLayer offers SuSE and a couple VPS hosting companies do the same. I'm wondering how many large-scale sites are run on this operating system.
how can I install a VNC *(graphical remote control) on RHEL 5.0?
would someone give me a detail instruction and links?
I olled online and tried to use yum and up2date and they said the package could not be found
I did rpm-q gd and gd is installed but i need it for php-gd.
I looked on the web and i do not see a version for RHEL.
My server is not sending mail for about a week, and i dont know what is the problem and how to fix this.
also, in PLesk, it still states that Mail is on and active.
Could anybody point me the direction how to fix that?
i am having a server runnung RHEL 4
With Red Hat Enterprise Linux 4 (RHEL 4), are updated packages made available, or are only security patches backported? Specifically I'm interested in vsftpd. Version 2.0.1 is included in the RHEL installation on a server I'm working on, but there is a bug fix in v2.0.4 that I'd like to get access to.
Is there an easy way for me to browse / search what packages are available for RHEL 4, preferably via website?
My data center happen to install RHEL 4 without a swap partition
Is there anyway to fix it without an OS reload?

Is there a Windows GUI software for remote Admining servers that run on Red Hat Linux?
FYI: Currently I use Putty for remotely managing our servers.
So if you can recommend a GUI like Windows desktop software for remotely Admining servers running Red Hat Enterprise, I would very much appreciate that.
FYI: we have like 10 dedicated severs, so a desktop GUI that would allow one to monitor/manage multiple servers would be best. But if the GUI that you think is best can only remotely connect/manage one server at a time, requiring disconnecting to connect to the other server to Admin it, that is fine.
Also, I would love to hear what you think is the best book, best tutorial and reference guide for remotely Admining servers running RHEL? I am not looking for one of those books that are 1000 pages, but something that is a few 100 pages and can be read in 1 month assuming a few hours per day of reading.
I seen where a lot of server management companies are charging big bucks for this, so this might save you some time and money.
First
Code:
nano -w /etc/yum.repos.d/dag.repo
Insert
Code:
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1
Then yum update and search for ffmpeg and install all ffmpeg packages including devel.
Seems there is some lib problems along the way so in /etc/ld.so.conf
add
/usr/local/lib
then
ldconfig -v
To install the php extension follow the simple directions on [url]
Then you should be all set!
Tried and tested on 2 different centos server, works fine.
I have 2.4.x version installed on RHEL and I need to install same version on Solaris 10. How can I find out what packages/modules were compiled for RHEL so that I can download same for Solaris and compile them.

View 13 Replies View RelatedI just got a Dell 1600SC dual xeon 2.8 from the Planet with a Dell DRAC3 remote access card. In my RHEL3 system this hardware combination works great, but in the new RedHat Enterprise Linux 5 system the DRAC accepts no keyboard input after RHEL5 loads, thus making it impossible to login to the OS through the drac remote console redirect. Tech support suggested it was because the RedHat Enterprise 5 and CentOS5 kernel does not load the PS/2 keyboard driver which is required for the Drac3 to accept keyboard input. (a drac4 works, but that's not an option for this server I would guess.)
At tech support's suggestion, I added
atkbd.set=2
to the /boot/grub/grub.conf file
rebooting had no change - still text input to enter the bios, but no text input to login to the OS.
I also added
serial --unit=0 --speed=9600 -word=8 --parity=no --stop=1
terminal --timeout=2 serial console
which I saw in /etc/grub.conf (which is not linked to /boot/grub/grub.conf but instead a separate file) but still no luck - no keyboard input accepted through the drac3 remote console to login to the os through the drac console redirect.
Has anyone solved this hardware/software combination? Or is RHEL5 simply not going to be backwards compatible with the Dell DRAC3 hardware?
Any ideas, suggestions, or solutions would be greatly appreciated as I've been working on getting a solution for this for a week now and no closer at this point.
I would really like to have the DRAC as a backup connection with my server incase any firewall or software update issue ever prevents me from connecting via ssh. I hate to have roll back to an older OS though to get it. I'm stuck.
This is the scenario, domain.com are setup on server1, however server2 also has the same profile of domain.com as we use ns3 and ns4 using domain.com. This works fine with the nameserver setup on server2.
However I encounter problems as the emails from server2 won't reach server1 as there are duplicate profile on server2.
My question is how do I setup the DNS in cpanel/whm from server2 so the emails from server2 will reach server1?
Server1 (www.domain.com)
ns1.domain.com
ns2.domain.com
Server2
ns3.domain.com
ns4.domain.com
