VPS For CPU-intensive Work
Jul 14, 2008
I'm working on a new project that involves some heavy data processing in the preparation stage. As an example, one of the setup jobs is now running on a P4-3.0HT desktop at 100% CPU and I estimate it'll be finished in just under a week! Memory and i/o usage are minimal but it's extremely CPU-hungry.
There are other similar jobs to follow and some correlation between the number of cpu cycles and the quality of results so I foresee an ongoing need for computing power for at least a few months.
Viable options are to continue running my own hardware (probably supplementing the P4 with something a bit newer), Amazon EC2 or a cheap dedicated server - I can get a good handle on the cost and performance of each of these.
But I wonder if I'd get more bang per buck from a few VPSs? Some of the VPS benchmark results are spectacular so I suspect the answer could be yes, in the short term anyway. But I don't want to hog the host-node's CPU to the point where it degrades other users' performance or gets my account shut down... Then again, judging by the performance of the VPSs I've used for hosting the node seems to have a lot of spare CPU available...
So (finally) to the questions: Am I crazy to even consider this? If not, which technology would be most suitable? (I'm thinking Xen because of its reputation for better isolation.) Has anyone else done anything similar?

my client a dedicated server which could handle the following things.
1). Intensive DB queries done from many operators for custom project.
2).DB when info process completes, Generates a PDF which would be upto 10MB in size.and also runs MAPLAB Applications.
3). should be able to run back-up's or please suggest an alternative to always have a copy of recent data.
4). pro-active scanning on Incoming FTP content for Viruses. (is it possible ?)
Considering softlayer with:
either
Single Processor Quad Core Xeon 3220 - 2.40GHz (Kentsfield) - 2 x 4MB cache
8 GB RAM
+ 147GB SA-SCSI 10K RPM
OR Preferring
Dual Processor Quad Core Xeon 5335 - 2.00GHz (Clovertown) - 2 x 8MB cache
8 GB FB-DIMM Registered 533/667
+ 147GB SA-SCSI 10K RPM

I have two VPS's which run a single MySQL intensive site. The first VPS runs cPanel and has about 50 databases, 200mb each. Second has another 30 databases, of the same size.
What would be the best method to backup this website daily?
At Current;
I use automysqlbackup to backup all the databases at midnight (this crashes the VPS's for about 10 minutes each night). This dumps each one into a zipped file.
Then the rsync copies the changed files (forum attachmenets, cpanel changes etc(whole server)) to an off site location.
Are there any easier ways to do this? The databases are most important!

I own a couple of servers xeon setups. All use cPanel/WHM.
A client yesterday asked if we could have ffmpeg-php installed on the server so that they could run phpfox.
I have heared ffmpeg is resource intensive? Will it make a big difference on dual core server? Should I install ffmpeg-php or risk losing a client?
If I should install ffmpeg-php I have been having trouble doing so, can anyone help me with this.

I would like to know how resource intensive is ClamAV Scanner. Should I allow it or not to my VPS clients/resellers?

We were on shared hosting until we were asked to move off due to our database using a lot of the CPU - how much, we dont know.
Anyway, moved to a 1GB Hyper-V VPS, seems like we have one core of an E5420 but presume the server is shared between 12 people.
When our ASP application runs, the MSSQL server reaches 100% CPU and the website performs slower than the shared server we were on.
Where can we go from here? Seems like going from shared to a Dual/Quad Core Dedicated Server is a large jump and a massive jump in price.
What about a host with a high performance dedicated server for MSSQL shared between customers.

Calling on all hosting and server experts here. (If you're not an expert, still feel free to take an educated stab at this. But please leave out total made up answers or foolish answers like "Have LittleJoeShmoe Hosting services do it all for $9.99/month".)
Scenario:
If you knew or were planning on developing a site that you knew would generate millions to tens of millions of page views a day, how would you go about supporting a site of such traffic? The site would not serve up videos, but the average page size would contain up to 75-100kB. It would incorporate databases (user logins, accounts, user submitted content, server side scripting, CMS, etc.)
Don't assume anything. Don't assume you have too little or too much money. Just, what would you plan out to accomodate such a scenario?
What hosting companies would you use? Would you do it in-house and build your own datacenter? Farm out the server management? How much would it cost to implement your plan? What platform would you recommend for a site to handle this much traffic?

I'm having exec cgi issues,
CentOS 5.3 x86_64, Linux, Apache/2.0.63,
cPanel 11.24.4-R36167 - WHM 11.24.2 - X 3.9
Error is,
[an error occurred while processing this directive]
If I "uncheck" IncludesNOEXEC in Apache Global Configuration the error disappears, but the SSI doesn't work. If I check it the error is there, but the SSI works.
Here's what I have done so far,
Through WHM,
Main >> Service Configuration >> Apache Configuration,
Pre Main Include, Pre VirtualHost Include, Post VirtualHost Include,
I added,
Options +Includes
AddType text/html .htm
AddType text/html .html
AddOutputFilter INCLUDES .htm
AddOutputFilter INCLUDES .html
Options +ExecCGI
AddHandler cgi-script .cgi .pl
I also added this to the httpd.conf
<Directory "/">
Options +ExecCGI FollowSymLinks Includes IncludesNOEXEC Indexes -MultiViews SymLinksIfOwnerMatch
AllowOverride All
</Directory>
Options +ExecCGI
AddHandler cgi-script .cgi .pl
Then I tried,
Options +ExecCGI
AddHandler cgi-script .cgi .pl
in the .htaccess file

After spending nearly 4 days trying to get ftp working on my server i still haven't achieved it. I got a server with a default install of plesk and cent os 4. I update to 8.2 and when i first go to try ftp it says "server closed connection" on my ftp client.
So then i tried updating 8.2 again and the installer failed. So i tried manually installing both proftpd and pureftpd via ssh and yum and it fails to install. I've also restarted the server a few times. I've tried logging in with every single username/domain/i.p. assigned to the server. and i've had no luck.

how does SSH work and really what is it.
This is my knowledge, I may be wrong or right:
There are two ways of controlling your server, through control panel and through SSH, now SSH is where you type in codes to control your server.
Now from what I know you can't login to SSH alot due to security reasons.
I was wondering, if I have a forum can I login to SSH everyday to back up the database?

Whenever I tried to upload large files to my server it restarts the upload again and again and never actually uploads. It just keeps overwriting the previous file. I don't get any errors? It just automatically reuploads and overwrites the files everytime.

My site is under DDOS attack. I run this command
netstat -an | grep :80 | grep ffff | awk '{print $5}' | cut -f 4 -d : | sort | uniq -c | sort -n | tail -10
And find a lot of IP that are attacking. After that, i run
iptables -A INPUT -s xxx -j DROP
to block IP, and
service iptables save
service iptables restart
But when i run netstat command abouve, i found IP are attacking still available, it seem iptables don't block it?

some clarification with regards to Reverse DNS.
An example ip: xx.xxx.xxx.xx is owned by A Company via a DC. The they have their name allocated to the netname and description when i look up their ip address.
I have my ip xx.xxx.xxx.xx this is me and it currently contains my DC's name throughout when i look it up as the description and netname...
Both are from the same DC however the other company has their name allocated to the ip address and i would like to do the same. Does this require Reverse DNS? It dosent involve domains surely does it?

I have been using apache and php-cgi and it works well together but when I tried to use
mod_rewrite it stopped working and I got "Internal Server Error" result.
Apache error log showed "FastCGI: incomplete headers (0 bytes) received from server"
I think that mod_rewrite rules are ok because when I refer to some HTML file then it all works.
Apache 2.2.14 and php 5.2.11

Like the title says, I just moved my site over to my own server, and it is running cpanel. Anyways the main site [url]works, but [url]does not.
What is really strange is, [url]works fine as does [url]
So I figure there is something I have to do to get it all to work right.
The other issue is that if you are logged into [url]but goto [url], you are not logged in anymore, but if you go back to the original link, then you are still logged in. This happened on the other guys server before with the main site as well.

when I try to go to a site of mine with the www like this one [url] It won't work but if I take out the www like this[url]it does work.
I'm not sure what could be causing this. As far as I'm aware everything is setup okay. I understand it's impossible for anyone who reads this to properly diagnose the issue without access to my server.

Lighttpd works well with static file.
But for php, it's totally not good for me
I just install lighttpd and php.
By [url]
Now It takes about 10 seconds for the
server to response.
Here is a part of config file
############ Options you really have to take care of

server.max-keep-alive-idle = 4

server.max-fds = 8192
php.ini using the default one
Here is the link to it
