Server Load - Balance With External Host
Nov 7, 2008
I have one dedicated server that hosts a PHP/MySQL highly dynamic site. In peak periods my site is starting to get high load (still very manageable but enough to warrant thinking about the future). My site is mostly images - photo gallery type stuff.
I've thought about using Amazon WS to host images from my site but it works out too expensive as do other similar Content Delivery options.
From what I can tell, when the load is high, mysql CPU usage isn't too bad, it hovers around 20% and peaks to 60% every 20 seconds or so, so my assumption is that the load is partly from apache (I see lots of apache processes in peak periods).
I am considering just get a cheap VPS hosted elsewhere that will be used as a static image/file server to release stress from my main server- How much stress would this help release?- Any other suggestions on solutions?
- I would have to do quite a bit of work to my application to ensure images are posted to this server and not my main server which seems a pain (or cron these tasks).

We have two dedicated server on that flash online arcade games website has hosted. Due to overload, server gets down server & hangs. So that we like to share the server load with two server.
Please find below the details our server configuration.
Processor : Intel 2.13 GHz Xeon
Hard Disk : 250GB ATA:
Control Panel : Cpanel (Installed on both server)
Apache Version : Apache/2.0.63
PHP Version : 5.2.4
MySQL : 4.1.22
I have been updating the PHP files with RSYNC command for every 15 min. MySQL Database we have put in different server (So I think no need to update).

i want to build three servers A,B,C,
and put websites on them.
i hope B and C can rsync the data from A,
when server A is unreachable,
all the connection will be pushed to server B,
if A and B are all unreachable,
all the connection will be pushed to server C.
when A or B be back,
i hope they could rsync with server C to get the same data,
and then all the connection will be pushed to server A,

I am completely new to apache and I had the load balancer set up for a single domain that was working perfectly fine, but when it came to multiple domains i couldn't, for the life of me, figure out what to do.
There is example.com sub.example.com and otherexample.com
I had a single node set up for this but I want to experiment with the balancer. I have scratched Google and I only found broken info which couldn't explain much to me. Here are my domains
<VirtualHost *:80>
DocumentRoot "/var/www/domain.com"
ServerName domain.com
</VirtualHost>
[Code] ....
Any example configuration of the default file.

I am an IT manager at a small company. Currently we host an ASP.net based web application (on an IIS server) that we do most of our business on. It was grown in house and uses our MS SQL server. We are looking at expanding this application within the next few months, and I need it to be "bulletproof", as in almost zero downtime.
The website also references and pulls up scanned documents that we have on a NAS server. Currently it is around 300 gig worth of documents, but expanding around 200 gig a year.
Ultimately, I would like this to be hosted someplace where there is a constant backup of the SQL and website. And someplace I don't have to worry about the hardware, because I am a one man operation and don't have all the needed experience to deal with the web application.
would it be beneficial for me to host the scanned documents onsite, and have a hosted solution reference them back at our HQ? I could put them in a DMZ or something like that.

I run Lighttpd and can push out 50mb/s and 500 connections with load .05 .10 .12.
My problem is not server load but bandwidth load.
Is there a way to balance bandwidth in that if 1 server is getting 40mb/s to push it to another server so that both servers can be doing 20mb/s each?

Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.

What difference in page load time does it make if I move away from GoDaddy hosting? Or doesn't it make much difference? If it does make a difference, what kind of percentage improvement are we talking about?

The last 2-3 days my websites on my vps all started acting funny. Randomly throughout the day they will all just stop loading. If you go to one of my sites they will just load and load and load and eventually time out after 5 minutes.
To fix this problem, all I have to do is reset Apache in my WHM. Everything will be fine for awhile until it decides to stop loading again.
I've been talking to tech support for 2 days. They're out of options. They tried banning some IPs as they thought I might be getting hacked. They tried moving me to a different host machine. They've checked all my logs... there are no errors or problems with the vps. The server load is always very low. Memory is always very low.
I run about 15-20 websites on this VPS. Two of them are vbulletin (v. 3.6.4 and v3.6.8) and all the rest are wordpress).
My VPS is hosted with ServInt.
Server Version: Apache/1.3.39 (Unix) PHP/5.2.4 mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4
mysql (5.0.45-community-log)
I get these emails all day:
httpd failed @ Wed Jan 9 06:10:42 2008. A restart was attempted automagically.
I am completely out of ideas and options. Can anyone think of something? Think outside the box... make random suggestions. I don't care, I need to try something.
I most recently added 3 or so brand new websites to my vps about a week ago. However, they are just running wordpress so I can't imagine they're the problem.

We've had a VPS for just over a month now. I am not going to mention the host by name (yet) but they advertise here and other people here reported liking them.
Sadly it's not my experience and I regret my purchase.
Every morning for the past few weeks, we get load spikes every 30 minutes that make our site unusable for a minute (on our VPS, any load over 1.0 is sluggish, over 2.0 is virtually unusable, over 3 is unresponsive)
Here's a series of days as an example:
[url]
The worst part about this is the host insists 1. either it's not happening or 2. they can't find it
I know it's happening because when I try to load a page on the half-hour, it takes over 13 seconds (less than 1 second normally). And it's fairly obvious it's someone doing a cron job with some nasty downloading, uploading, or maybe a massive mysql update.
Someone tell me what to tell them because this is driving me out of my mind. The load is NOT being caused by ourselves, I've made sure all our cron jobs don't happen on the exact half hour and we get lots of traffic later in the day without loads.

I have a -I think- common issue, one external server available from internet and an internal server for local only.
I want that to ask for [URL] ....
I can get the content of an internal server. For this I tried this at httpd.conf:
Redirect /site http://in.ter.nal.ip/site
but browser changes to internal IP and obviously I can't reach it.
So, I need that when external server detects that I want to see internal server content, it ask to internal and external itself answers.

we have a cpanel server that has been running our website and emails. We have just obtained another dedicated server. I would like to keep our first server running our website and move all of our email for the domain to the new server. The second server has the same setup and runs cpanel as well. Can anyone point me in the right direction to achieve this?

On a CPanel server, I have one account where mx records are configured to route all the e-mails to external mail server. Everything works great, except when the e-mail is from another account on the same CPanel server, it doesn't reach external mail server, I think it goes to e-mail box on CPanel server.
Is there a way to fix it? (How to send e-mails from the CPanel server to external mail server?)

I have a web server and two DB servers. I use a third party DNS solutions. I would like to move mail to a totally separate server.
My question is... How exactly would I do this? I assume that I install something like exim and then use the PHP mail function like normal except configuring it to send via the new servers IP address.
Then I suppose I would create a record for mail.mydomain.com pointing to the new server and then create an mx record to use mail.mydomain when receiving mail from mydomain.com.

We require a server with 10+ IP addresses (Each one with a separate OS and external IP Address, i.e myip.dk)
This is to be used as an added security level for our employees logging into our system from outside the office. Our system monitors the IP Address and we need to restrict access to certain items depending on the IP. We basically would like to set up multiple VPS on one server.
Can you confirm how this would work?I know we can buy a Windows VPS for around £15, but we need multiple of these (10-20)and figure our own server might be the way forward.

app and content are separate physical machines
I want [url]to be processed by app directly, which it's doing now
I want [url]or [url]to display content from content, either directly or through a hidden/stealth redirect.
How can this be accomplished? How else can I have one URL serve from two different servers other than using subdomains?

way of going about the following:
I have a client who has hosting with another company for their website and they have their own internal MS Exchange server for email...
In order to switch the hosting to one of my servers they just need to alter the A record for the website to my webserver's IP address at the registrar - correct?
They also want to start sending a "mailshot" to existing clients - what is the best way of doing this? I have no experiance of Exchange Server so I am thinking of running something simple like phpList on the webserver but how can this be configured to use their Exchange Server?
I am thinking that if I just setup phplist as normal then the emails it sends would bounce, is the trick to setup phplist differently or to change the servers DNS settings for that domain?
the server is running CentOs and cPanel

I have a local web server that I want to make available outside of my local network of two computers. I configured NAT at my router, configured the firewall. I Typed the external IP and got nothing, while I still was able to access my web server by typing "localhost", I tried both IIS and Apache, but what is interesting is that fact that the other people can access my web server via that external IP, I just cannot access it from my local network.

I get the following message if i try to migrate a domain from a Windows Plesk (9.5.5) to PPA:

Is it possible to make Joomla connect to an external mysql database server?
Meaning, the database for Joomla won't be local, but on another server.
Will it work by just entering the mysql hostname, user and password in Joomla's config?
What issues might arose by doing this?

I have Plesk Panel installed in server 1 and mailenable in server2. I disabled mail service in server 1 and configured external mail (by the way, I cannot start it back) - Tools & Settings -> Mail -> External SMTP Server to my server 2.
Every contact form created with Presence Builder never worked, and I do not know why. Is there any work around? When Plesk is going to handle e-mail forms with a PHP file?
