I want to be clustered so that if one node goes down then the second one will automatically take over. I have done that with HA in RHEL but I want to use centos clustering solution for this. Also how willl they share the web contents and mysql database among two nodes I have no idea. I have managed a iscsi target to store contents but it doesn't work as expected.

View 4 Replies View RelatedI am getting frustrated to the fact that I am in charge of developing a Enterprise class solution for my company and I don't find the right answer on the WWW. I have 3 mail servers that I want them to share a Global File System (GFS) that will be mounted via ISCSI on a RAID1+0 SAN Md3000i device. All the documentation that RHEL offers include the setup of DRDB or VLS Clustering.
My intentions are not to setup clustering on these servers, at least for now, however I want them to share access to the same block device, giving enough write/read access throughput . My question is, have you done something like this ? Do you know of any good Tutorial that you tried, and worked for you ?
Used to work fine, mybb forums and a blog, accidentally chowned everything to wrong account, then back to root, fixed mysql, shell and php and it got back up again yesterday, made a new database and updated some packages using webmin (OpenSSL etc), tried to install virtualmin but qMail blocked it, few hours later out of the blue all our php files download as .bin files, as downloadfile.bin on my android phone but others on our game server reported it downloading too.
We shut off apache for obvious security reasons and are considering to close shop if we cant fix this.
selinux and psacct is disabled in this system (RHEL5.6 2.6.18-194.11.3.el5 SMP x86_64). After performing a yum update, the syslog is flooded with kernel audit messages (related to PAM), even though audit service is turned off. Is there a way to disable this verbosity?

I have installed apache tomcat 5.5.27 in centos5. I edited the server.xml file also. The startup.sh and shutdown.sh commands are working fine. But tomcat is not opening in the browser. Can you suggest me something or tell me the steps involved in installing tomcat. Is admin.tar.gz of apache tomcat required for its working?

I've got a problem with my Ubuntu Server 11.04 amd64, I think the problem comes from GRUB 2. Here is my problem : I updated my server and I now have Linux 2.6.38-10-server (in addition to 2.6.38-8) and, when I try to boot on version "10", I think I have a Kernel Panic because the screen keeps black and there is no use of the HDD (I can ear it working with version "8"). I also looked at /boot/grub/grub.cfg and I didn't saw any diference between the lines for v10 and those for v8 (except for "8">"10" of course).
I tried with Recovery Mode too, with this result : Loading Linux 2.6.38-10-server... Loading initial ramdisk...
> No use of the HDD (I don't ear it), and it's "frozen", can't do anyting but reboot it by ACPI (nothing happend when hitting "Num Lock") Another question : can we have no submenus in Grub2?

I'd like to build a server to run CentOS5 to host domains & run Boonex's Dolphin 7. I can't afford the hardware at present, but do have a spare laptop to test with. My two questions:
1) Is is possible to create a build on my laptop, with CentOS, PHP, Dolphin 7, DNS etc, and then create an image to transfer to the future hardware server when constructed? If not, are there alternatives e.g. to copy settings, and then paste then onto the new CentOS install? Anything else I should consider for doing this future move?
2) I presume it's not possible to transfer from 32bit (now) to 64 bit (possibly later) CentOS5?

I am trying to see if a can get a centos 5.5 server setup as an smtp store and forward spamfilter by following the Centos Wiki and the freespamfilter.org guide by Mr88Talent at [url], which relates to another linux distro.
The spamfilter is essentially working! however, i have one issue with DCC.
test problem:
I'm not sure if anyone else would be interested in a Centos version of Mr88Talent's tutorial, but a very rough and completely untested first effort is available at the following url: [url]
Any opinions on this setup or just a total slating of everything i have done wrong would be welcome as i don't want to waste time trying to use a setup that is just not going to be practical or reliable to maintain / keep operational.
I have read that yum update can break this type of system - which concerns me.
The intended use of the spamfilter is for a small business (only about twenty e-mail accounts). However, they still need to reliably receive e-mails (hopefully with less spam though).
I am using DEBIAN 6.0 and I wannna update my kernel from 2.6.32 to 2.6.38. Every time, I do it but after the installation & rebooting into the new kernel it gives me error "UNABLE TO BOOT INTO THE KERNEL".
View 1 Replies View RelatedI have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.

From F12 to F13. Is there anything I should remove before updating? I have few programs isntalled from source/binary installers in /usr for example. Would it cause problems?
And is there any chance to be able to switch from a 32 bit kernel to 64 bit kernel during the update? The hardware is capable of this.
9.04 this morning updated my kernel to I believe it is 2.6.28.18 and upon the reboot I had no desktop. It booted wanting to go into low graphics.
So I drop to shell and stop the gdm and try to run the latest nvidia run file I have and it hangs saying I have a x server running.
Otherwise I am needing assistance with getting my desktop back! I can boot into an older kernel and if need be I would like to roll back that latest update this morning, but once again I am forgetting the command line for that.
