i want to kill apache/http and restart it again automatically. i need this because sometime we are not in front of the server to fix an overload issue immediately, which can affect a server very badly. i believe many of us already face this kind of situation and hope there is some kind of script or way to do this.
I have heard a lot of cases when customers used forbidden PHP scripts on shared servers and as a result their accounts were suspended due to the server overload. I am just wondering what scripts it is desirable not to use within shared hosting packages?

Is there a way to protect apache server from overload? For example Nginx has a module called SysGuard when system load or memory use goes too high all subsequent requests will be redirected to the URL specified by the 'action' parameter.
I have a fairly busy server, and received a High Load warning from my firewall monitoring software. Showing a high 5 minute load average alert of 13.89.
I'm presuming extra memory and a more powerful CPU would be required to sort this out?
Time: Thu Jul 3 12:22:06 2008 1 Min Load Avg: 42.90 5 Min Load Avg: 13.89 15 Min Load Avg: 5.82 Running/Total Processes: 51/359

I have been receiving these a couple time a day lately and not sure what to do or how to go about checking what might be overloading the server. IF this looks familiar to anyone, I'd appreciate some helpful tips. I'm still a novice, but can muddle my way around the server if given enough guidance. Here is the email I've been getting:
"IMPORTANT: Do not ignore this email. This is cPanel stats runner on host.myserverhost.com! While processing the log files for user xxxxxxx, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is 19:20:10 up 2 days, 7:06, 0 users, load average: 15.17, 13.24, 8.00 You should check the server to see why the load is so high and take steps to lower the load. If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes)."
I guess my question is, how would I go about determining what is causing the excess load? Seems to happen even when not many folks are on my site.
I'm on a low-end dedicated server that I run 2 decent sized blogs on. I'm getting several traffic spikes a day where the load goes through the roof and I think I need my server optimized.
My server admin says I need a bigger server and he has never steered me wrong but this is ridiculous:
My blogs use Wordpress as its blogging platform....I know they hog server resources and I've recently installed Super cache so that seems to help.
I average about 5,000 pageviews a day and I would think even a low-end box should handle this but maybe I am wrong.
Does anyone here use VMware server on a dedicated server to run Windows or other OS? And in terms of IP address how would this work? Do you need to set the VM as being NATed, or does it have it's own external IP? In terms of performance on a typical 100$-200$/mo dedicated server, how good is it? All these factors depend on a lot of things and I realize that, though. (what apps run, etc)
And do server providers even allow to install something like this? I've never leased a dedicated server before but I'm thinking of getting a linux one, but also running a windows VM for a RunUO server, and unfortunately that only runs in windows. I want a linux server as I prefer LAMP for hosting, and I'd try to get a few clients on the server just so I can pay it off monthly. Also Linux servers are generally cheaper monthly and I like the idea of using SSH tunnels rather then straight RDP, which gives me chills just thinking of, from a security perspective.
Recently, I installed VMWare Server 1.0.4 on my dedicated server.
When I tried to install my private IP on my VMWare, I had no clue how to do that. I used NAT networking to share my main OS with my private VPS, but when I try to run a service that needs the port XXXX to be open, it wouldent let me use it.
For an example, my main OS IP is 82.00.000.000. My VPS is sharing the same IP address with the main OS. I tried to run an Apache service on my VPS, but when I try to access it by the IP 82.00.000.000 it gives me a connection reset page.
This also happens on other services like FTP and stuff.
My VPS is running Windows XP Professional SP2 with a legal retail license and my main OS on the server is CentOS 4.5
Has anyone every done this before? There are so many better bargains out there for *nix based machines. We'd like to use some of these to host VMWare Server and then run one of our windows images on it.
I'm having issues after changing my system time and rebooting for whatever reason it didn't take effect but now my VMWare servers wont boot. I get this error when trying to run a vmware-cmd
[root@plexus ~]# /usr/bin/vmware-cmd -l /usr/bin/vmware-cmd: Could not connect to vmware-authd (VMControl error -14: Unexpected response from vmware-authd: 511 Error connecting to /usr/sbin/vmware-serverd process.) [root@plexus ~]#
also when i try logging into the web interface same error.
I have configured and install VMWare Server on my server and currently trying to install Plesk. I have gotten the network working so I can download.
I want to give the VMWare Virtual Machine it's own IP so I can connect via PuTTY instead of the console, which e.g. does not let me paste url's (plesk download url is long).
I am planning to host a few websites on the Plesk Virtual Machine. I have added the IP my network provider given me using 'setup' in CentOS and it's listed in /sbin/ifconfig, but does not work yet.
Do I first need to add the ip to the host server self? Or can a VPS directly use an ip?
I have Windows Server storage server. However I need to run some Linux scripts. Is it possible to run possibly VMWARE to have Linux so I can install the scripts use the Windows which has content to be used.
Kinda tricky I know but worth a shot.
Windows - Has all the content , but can't run scripts such as file hosting , streaming server (WMV wont do) , HTML/PHP server scripts.
I installed VMWare Server 1.0.4 on my dedicated server, and set-up a new Windows XP Professional VM.
I have 3 more IP's that are not used.
When installing the VM, I used NAT networking to share my main OS network with my private VPS, but basically no one can access the VM from the outside world. I can surf the net while being on NAT status in the VM, but if I try to run any service like Apache, no one can enter to the service besides the localhost.
My VPS is running Windows XP Professional SP2 with a legal retail license and my main OS on the server is CentOS 4.5 (detailed hardware is mentioned below)
Do you have any idea how can I configure my network so anyone can enter the VPS?
And please, if you can explain me step by step because I'm a real newbie hehe

Also, I saw some topics with solutions but I didn't got a chance to understand something ;
ow and sorry for my English, I know its not perfect : P

I yesterday installed VMware Server under Windows Server 2003 x64, Enterprise Edition, and have this morning noticed the message 'Service unavailable' when browsing to a website hosted on the server under IIS. I have briefly looked into the problem and found the DefaultAppPool stopped, but after restarting it, it resets back to the stopped state when I once again browse to a hosted website.
Does anyone have any experience of this problem and a workaround?
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.
Our company website runs on a Win 2003 server with ASP.
Now we also want to run some new PHP applications (e.g. MediaWiki). I think of running them in a (Linux) virtual machine on the Win 2003 server, to keep everything separated.
Does anybody else use VMware to split his dedicated server in several parts? It sounds like a good idea to me, but can not find much information about it. Or are there better alternatives?
i have vps 512 MB ram From HostForWeb working Fine! in 160 websites! Hosted But! in swvps.com with 2 gig ram! Low Working! OverLoad and CPU Usage is Red Alert But HostForWeb VPS with 512 MB Ram good Working I Dont Know Why SWvps.com Is Low with 2 gig ram for me?
I am not sure if my dedicated server is being attacked or if it is legitimate traffic. I need help figuring out the difference and if it is an attack, how to prevent it, and if it is legitimate traffic, how to configure the server to handle the load.
SoftwareCentOS 5.3-32 Apache2 MySQL 5 PHP 5 When I do ps aux|grep httpd|wc -l I get the count of current connected clients of 259 which is always maxing out my MaxClients of 256. I had increased it to 512, and it maxed out, I had increased it to 1024 and it maxed out, and lastly I had setup to 2048 and it works, but slows the entire server down.
