Red Hat / Fedora :: Build A Server To Run CentOS5 To Host Domains?

Jul 6, 2010

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?

Server :: RHEL5 Won't Boot From LUN ID 1 - Where To Change It

May 8, 2010

I'm trying to get RHEL5.3 booting on an IBM Blade off a SAN disk, but it refuses.Our storage is presented on LUN 1 as due to the IBM XIV SAN, we cannot use LUN 0 when presenting volumes. We believe that when the installer tries to configure the boot LUN, it expects to see it on LUN 0 but we can't use that. This leads to a problem where after installed Red Hat, it asks me to remove the CD and reboot, but doesn't load anything other than a cursor blinking at me on the monitor.I currently can't change the LUN ID on the SAN, so I've been trying to amend things to get it to work with no joy.

Ubuntu :: Processor Type For New Computer Build?

Jul 21, 2010

A processor is very important to me and I'm curious what processor to get for a new computer build. I will be using Ubuntu for most things except iTunes, HD movies, and a few low spec requiring games on Win 7. I am building it as right now I have a half year old netbook that can do most things just fails at game play and movies but it's alright. And I have a desktop with just Ubuntu that's about the same quality but 8 years old. I want to build a computer that will be very fast for the next 4 years enough to get me to college and buy a nice laptop. I am on a small budget of around 500- 750 dollars. I have most things picked out but processor has me stumped. To me processor is a bit tricky to replace and I'd rather get a higher-end one to start and stick with that than buy another CPU two years down the road.

I don't mind upgrading RAM, GPU, and or even the HDD at a later point but I want to get the CPU as close to perfect as possible. First I heard AMD processors tend to be a bit hot. I was wondering what cooler is $50 or less that does a great job at cooling a AMD AM3 socket CPU. I do plan to overclock a very small bit perhaps up to .3 GHz plus max. First I was thinking a nice core i5 at $200 and never really checked anything else. Then, I was thinking a hexa-core at 2.8 GHz I think but decided too much and didn't need six cores. The AMD socket type also supported USB 3.0 which I instantly fell in love with. Then I found a quad core Phenom II x4 black edition at 3.20 GHz for around $160.I liked the core unlocker and it looked incredible. Now I'm rethinking a bit again.

I found a dual-core that is same thing as the other AMD one above except well only two cores. I think that would do me fine I'd I'd save $60 by getting 2 less cores. With the things I use a computer for (Ubuntu, Win7, HD quality playback, minor gaming like Runescape, and small multitasking like openoffice a browser or two and perhaps some pictures, game or movie.) I also want to be able to do this quickly for the next 4 years without a hiccup or at least to a minimum if possible. I really don't want to upgrade CPU once I get that bad boy in there. I also want it ready for higher versions of Windows like Windows 8 is supposedly coming sometime in 2012 I've heard. I just want the best CPU to be fast and efficient, run cool, and work well for me for the next 4 years.

Programming :: GCC And G++ Build Results If The -march=TYPE Is Not Specified?

May 25, 2010

I'm sure this has been covered somewhere before, but I couldn't find anything and so figured I would post here. I have been using Linux OSes for the past couple of years and also using GCC/G++ for application development. However, I have almost always been on x86 systems and never gained much experience using the wide range of optimization options available.

My question is, if I do not specify the -march=PROCTYPE option, will GCC still be able to detect the current architecture and build the code accordingly? I primarily ask this because I am working with an x86_64 system, and specifying -march=x86_64 in my makefiles generates errors about it being an unknown processor type, even though the CPU and OS are X86_64. I know this sounds like a newbie question, but it's just ground I've never had to cover before until now.

Installation :: Dual Boot Windows XP And CentOS5

May 12, 2010

I have an existing desktop with Windows XP. I have added another hard drive on which i have installed CentOS5. I have updated grub.conf as follows:

# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that


I am not sure what to do next. If I remove the new hard drive the machine boots into WindowsXP so the I am not getting to the Windows bootloader from CentOS.

CentOS 5 Server :: Web Server Clustering With Centos5.2

Mar 22, 2009

To clustering my web server so that it becomes Highly available. Its currently running php, apache and mysql with no redundancy in place. 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.

Server :: Setting Up GFS2 On Centos5?

Nov 2, 2010

I 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 ?

Server :: .php Downloads As Downloadfile.bin On CentOS5

May 17, 2011

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.

CentOS 5 Server :: SMTP Spamfilter Centos5.5 Dcc - On Config ?

Mar 3, 2011

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 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).
