we have done a minimall install of centOS. We don't use software RAID, and after doing a "lsmod" we see a lot of modules loaded we dont need.
So I tried to remove the DMRAID because we don't need it. I'have added the dm_mirror, and dm_raid45 to both /etc/modprobe.d/blacklist:
blacklist dm_raid45
blacklist dm_message
blacklist dm_log
blacklist dm_log
blacklist dm_mod

I have a dedicated server. It doesn't have any GUI (gnome or something like that), so i need to use terminal, which is hard for a non-advanced user. So i have a few questions:I'm hosting a CS server and a few other servers later on. But right now only CS server. With it i need to start another perl window, which updates the stats to the website and database.So how can i start both server, that program and maybe use the console at the same time?Another question is: when i quit the server, it automatically restarts. How can i just kill the process? I don't want to restart my server every time i want to shut down the CS one.
About perl: how can i install per modules and how can i know the translations of perl modules from windows to linux names?And is there any firewalls by default clean installation, which might 27500 port and any connections trough 3306 to the database on my web server? If no, how come, that my program is unable to connect to my website database?Will my own email server take a lot of resources? Which only i would use and wouldn't receive much mail? And are there any guides how can i do that?Will a web server, which wouldn't take much visitors each day take a lot of resources?

I am relatively new to CentOS. I attempted to install 5.3 with firewire several weeks ago and abandoned the install because it was taking too long to figure out the problems. I've had to revisit this and am having troubles with it. I was told that CentOS 5 has firewire 1394 support. When I did the typical install, it didn't physically (manually) install the video1394 and raw1394 modules. At boot up, my computer says that video1394 and raw1394 are "Module(s) not found". If I do <lsmod> I get (*snippet of o/p),

CentOS and RHEL even though I've been using various Debian/Ubuntu Distros for quite some time. However, I always used to install perl modules via apt-get or, if that did not work, via cpan.In CentOS, I tried installing a couple of perl modules via yum but there are only a very few available. When trying to install perl modules via cpan, the install process usually fails during the make process.I'd prefer to install those modules via the distribution's package manger yum as it's easier to resolve dependencies. Are there any repositories I should add to have more perl packages available? (Where to add further repositories, I just know /etc/apt/sources.list in debian based distros)The other option still would be to install perl modules via cpan. For instance, when trying to cpan install Geo::IP, the output is as follows:
CPAN: Storable loaded ok
Going to read /root/.cpan/Metadata

this might not be a Centos related issue, but since I'm using Centos I guess it doesn't hurt to ask; I've used Ubuntu before and haven't encountered this. So, I've just installed Centos and Webmin and now I'm trying to configure the server. Problem is that on the Apache configuration page I don't have the option (should be there) to configure the Apache modules. I've attached a file to show where the modules option should (as before) appeared.

View 19 Replies View RelatedI am administrating a server with CentOS installed. It came with qmail and courier-imap preinstalled, and Plesk.I need to manually add email accounts outside of Plesk, because my 1-domain Plesk license only allows the creation of one email address (yes, it sucks).
When I say add email account I mean creating a new email address, have email for that address be stored in its maildir, and have a corresponding imap (and hipefully also pop3) account that will be able to read that mail. All this with virtual domains.I've already found out how to create the new email addresses for qmail, so that email for the new email address is being delivered correctly. Now I need to create the imap/pop3 accounts for courier.
For the qmail part, I create a folder in in /var/qmail/mailnames/virtualdomain.org/username and a maildir called Maildir inside it. This is how the first mail address was created by Plesk and i'd like to maintain the same structure. As I've said, the qmail part is already working, I need to get the courier-imap part to work. Ideally, it should accept login with both short (i.e. myuser) and long (i.e. myuser@virtualdomain.org) user names.
Currently the only authentication module that is enabled in courier-imap is authpsa, which is Plesk's authentication module.in order to add more authentication modules, do I just need to add them to the authentication module list in /etc/courierimap/imapd, or do I need to reinstall courier-imap with support for such authentication modules? I thought I would only need to add them to the list, but I've noticed that the /usr/lib/courier-imap/authlib/ folder only contains a binary called "authpsa". Does that mean that other authentication modules are not even installed? If so, can I install them without reinstalling courier?
The second question is, what would be the most recommended authentication module that would make it easiest to create new email addresses/accounts from the command line? I need to be able to write a shell scripts capable of creating a new email address with all that is needed, and I'd like to keep this script as simple as possible, so for example I'd avoid mysql-based authentication as it sounds rather complicated. And the last question is, if I do need to reinstall courier-imap, how can I install a package without recompiling it? Will my one existing mailbox keep working?

I liked to move away from LUKS and LVM.
I just like to have a simple hard disk with 3 partitions for boot, / and swap
What i did so far is:
1.) i unlocked the disk and copied the content from /boot and / to the new disk into sda1 and sda3 (sda2 should be swap)
2.) i changed the fstab
3.) I changed the grub.conf
Somehow my settings in fstab and grub.conf are being ignored and during boot my system still complains about the missing /dev/sda2 for LVM
I do not like to use LVM.
I expect this is caused by the initrd
I already did boot from the Live CD and did chroot into my system and tryed to make a new initrd.
I used mkinitrd without any options.
During boot i still get the LVM error message, complaining about the missing /dev/sda2

The screen came out.
But I am expecting a similar screen as CentOS 3 or 4 which display the package management by group of Desktop, Application, Servers, Development, System.
