RHEL 5 - 32bit V 64bit Running Cpanel 11 For Hosting
Jul 8, 2008
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.
while setting up a server which will host VPS's. Currently I have CentOS 5.1 x64 as the host OS, and I'm playing around with Xen for VPS's. Would you recommend a 32bit VPS, or a 64bit VPS?
2 server configuration will look something like below. I heard that the 32bit kernel is better for the web server since I'll have cpanel on it. Anyone able to confirm this or should I just put 64bit on both of them?
Web Server 5420 2.5GHz (Dual QuadCore) 2x250GB SATA2 (RAID1) 2GB RAM
DB Server 5310 1.6GHz (Clovertown, DUAL processor) 2x73GB SAS (RAID1) 4GB RAM
I'm in the process of preparing to install CentOS 5 on my server, and was wondering whether most people recommend going with the 64bit version or sticking with 32bit. My server's CPU is 64-bit capable (Xeon 3060 at SoftLayer), and I have previously run CentOS 4.4 64bit on it, though I did have some struggles from time to time getting things to work (following setup guides that tend to assume 32bit more often than not).
I'll be running just a standard setup of PHP 5, MySQL 5, and Apache 2, powering several moderate-traffic sites that run on the Drupal CMS (e.g. about 7000-10000 visitors per day total, though hopefully more in the future of course). I don't plan on running a control panel other than Webmin, though I might get DirectAdmin or similar in the future to make hosting some friends/clients a bit simpler.
Will going with 64bit offer any worthwhile advantage with this setup?
I was surprised when hypervm brought in a 64bit guest os. Maybe it's me..but...is this a good idea? Maybe it works fine.. it just does not *seem* like it would.
I am pleased to report success with my first attempt of installing Cpanel on a 64bit vps running Fed4. In fact..this is the first time in known history I have tried anything this..uhhh.."risky"..and it work the very first time. Cpanel had no problems completely replacing the already pre-installed plesk.
I'm currently hosting with softlayer and running the following:
4 super fast http servers on a load balancer with 1000 connections (costs a fair amount) - apache 2.0 1 fast mysql server (the server is starting to struggle but i'm concerned about expanding this because clustering mysql is very complicated in my situation) - mysql 5.0
I was looking at amazon s3 and it said it would only cost me $2,500 for my needs which is not only considerably cheaper but i think theirs would be even faster than softlayers with their network and the fact that there wouldn't be hundreds of mysql connections per second as there is now.
Money is not really an issue, I'm more concerned about flexibility and in case i get a ddos attack that i can handle it since softlayer doesn't provide ddos protection (cisco guard) on load balanced IPs and all IP requests to the server show as the load balancer IP.
going to be starting a file hosting site, i know that the main problem on these sort of sites for the owners is Bandwith and HD space. Just want to know some perhaps some advice on how to run this kind of business as far as the hosting part of it goes.
Do i just keep purchasing servers lets say at midphase for example they offer 10TB 250 Gigs of hdspace at 200 a month, so if i go over do i just keep purchasing servers and then load balance the site across all the servers i get? is that the basics ?
When sites start to consume massive amounts of bandwidth is their cheaper alternatives then just going with the normal BW that hosts offer, like working out deals with certain companies that specialize in giving BW deals, would CDN networks be an option?
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.
I created a new 'Hosting settings created' event running as root and with the highest priority with this command: /var/www/move_some_files.sh
I created a new customer with to test it
But, is not running the script! If I try some command directly on the event like 'touch /var/www/new_file' it's created, so the event is running, but not my script.
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?
I am planning to purchase 2 vps for my friends, 1 vps which I am currently in touch is providing wide range, they gave option for 32bit or 64 bit, is there going to be change in the performance of the vps based on this selection
and which is better for the future causes, this vps might have an community forum, few blogs and some file upload site,
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?
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.
