Which Versions Of Apache And Mysql Can Take Advantage Of Multiple Cpus
May 15, 2007
Are there particular version of mysql or apache that are best suited when you want to utilize a multi-core/multi-cpu system? For example, we are currently using apache 1.3 and am not sure if it has the inherent ability to use multiple cpus to its benefit.
Or would the fact that it spawns child processes take advantage as the processes will be spawned on the different CPUs?
I've a small reseller account with cPanel with 5 sites. After transfering to other host (full cPanel backup of old sites, restoring on new host) cPanel of 2 sites still displays the version number of the old host, the other 3 sites are correct.
I have tried to install multiple versions of PHP as described here: [URL] The option "Add/Remove Components" > "Web hosting features" > "Different PHP interpreters versions" is not available in the Parallels Installer. I am using Plesk 12.0.18 on CentOS release 6.6 (Final)
A really nice feature has been brought to plesk with the native support for multiple PHP versions now.I tried it out, but there seems to be an error in the session.save_path of PHP 5.5.23 (the one I tested).sessions.save_path points to /var/lib/php/sessions but the default before seems to be /var/lib/php/session so the folder does not exist.For now I simply worked with a symlink to solve the problem:
cd /var/lib/php/ ln -s session sessions
Not sure if other PHP version or other OSes (besides PHP 5.5.23 and CentOS 6.6 are affected).
According to: URL....I tried to install php 5.3...Before able to .configure php source, i must install several dependencies. I resolved most of them but installing libmcrypt-devel gives the following error:
to upgrade the PHP and MySql versions our shared hosting ocmpany is offering. We are now at PHP 4.3 and MySQL 4.014 I need to bring it up to PHP and MySQL 5.xx versions. Has anyone done this and if so what gotchas should I look for? what is the suggestes upgrade path not to affect clients using the older versions?
I'm desperately trying to find a hosting service that offers Linux hosting with latest versions of php (5.2.x), mySQL (5.1) and maybe CVS or SVN?
Space or bandwidth are not an issue (500mb space will be more than I'll ever need)
This will mainly will be a development/testing place. I really need a host that actually updates to latest versions of php/mysql/apache. (not the next day the upgrade is out but some time soon at least >_<)
Things like CVS / SVN, SSH access and access to change your own php.ini settings are more than welcome but I could live without.
Depending on where u are at on my site (documents pages, training, main root, etc.) will depend on which type of background, footer, header and the like you'll get. Now I was thinking. Is there a way to have multiple error messages for more then one page depending on where you are at on a site? Right now it's intranet site and a modded snitz forum. What is the code and were does it go and in which apache conf file(s) does it go in?
i have a site which involves heavy cpu use but its in a small private network with 3 other boxes which are pretty much idle, so im wondering is their a way to use the idle cpu time /ram possibly on my main server via the network ?
I have make an argument for going with Intel chips for some new platforms. These will be used in Xen VPS hosting.
Scanning thru the products of newegg for example, it would seem first that AMD boards (Opterons) are cheaper then Intel's 775 boards. Then the Intel boards also require FB-Dimms which is a bit more expensive then Registered ram.
I know alot of hosters here prefer going with Intel. Is there any other reasons then just following the crowd? I do know Intel chips perform better but does that warrant say 300 more dollars of going with an Intel based solution?
What would be some convincing arguments for going with Intel instead of AMD chips?
Many people have some problems with vmware server on some 64bit operation systems. If your server's ram is more than 6GB, you have to have a 64bit OS but I have tried to install vmware server on a 64bit server, it seems to be crashing my vmware server every 5 min and I cant use it more until I reset this service.
My site is databases driven and runs on around 15 mySQL databases. Im wanting to download a local copy of these databases daily, however, if i try and back them up via cPanel (on a WHM VPS) they give me blank files. Each databases is around 55mb and growing. I can back them up one by one via phpmyadmin, it just takes around 5 minutes per database. Meaning around 40 minutes per night..
Is there any solution for having a script downloading them automatically so i can download them via ftp? I've tried [url].htm but it gives me blank files.
"The Register reports that the world of current multi-core central processing units (CPUs) just entered is facing a serious threat. A security researcher at Cambridge disclosed a new class of vulnerabilities that takes advantage of concurrency to bypass security protections such as anti-virus software The attack is based on the assumption that the software that interacts with the kernel can be used without interference. The researcher, Robert Watson, showed that a careful written exploit can attack in the little timeframe when this happens, and literally change the "words" that they are exchanging. Even if some of these dark aspects of concurrency were already known, Watson proved that real attacks can be developed, and showed that developers have to fix their code. Fast..."

Our servers has been updated recently and my site is not working properly. It was working before the server change. When I click on the links, it doesn't update correctly, instead it gets the last cached data. I have to refresh each link for it to update which shouldn't be the case. I'm a front-end and have no access to servers. Could this be server-related?
I very much like the "readme.txt" that Apache appends to the directory listings. That is, when a browser GETs a directory, the text in that file is put underneath the list of files therein.
