i have one centos dedicated server and cpanel i will going to apache status is very request link and 2 site are very high in the list and my apache worked very hard and going to down any hours of your seems i must how control it?
View 7 RepliesI have a server running Apache 2 with php 5 as an apache module. There are 2 PHP scripts that get about 500k hits a day. These scripts have to parse data out of a remote webpage and display it on an image. They used to make loads go up to 40-50, but I have added a cache which only updates every 4 hours. This helped a lot, but loads are still around 10 when the script updates, and it slows down the server. Memory usage is fine.
The server is an AMD Athlon 64 2800+ with 1 gb of ram and an 80GB SATA hard drive.
Here's `top` when the cache had just been cleared.

How can I limit my dedicated server's resources ? For example, one of reseller provider's limits :

Resellers may not use more than 2% CPU daily, 3% memory daily, run more than 10 simultaneous processes per user, allow any process to run for longer than 30 seconds CPU time, run any process that consumes more than 20% of available CPU at any time, or run any process that consumes more than 16 MB of memory. Databases are limited to 16 max user connections with a max query time of 8 seconds. Cron jobs must not execute more than once every 15 minutes and will be niced to 15 or greater.

Server Version: Apache/2.2.9 (Unix) mod_ssl/2.2.9 OpenSSL/0.9.8b mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.6
I am in a bind with Apache's multi process limit. Let me explain what I am doing. There's this website which has career details of all the football players since the beginning of professional football. They have a simple web form which allows you to look at a player's profile by entering his name or his 7 digit numeric id number (on that website).
One of my client wants a list of all the players with a certain "flag" in their profile. So I created an automatic form submission and HTML parsing script to get details of all the players with that "flag" in their profile. Let me not go into too much details and tell you that after applying a few pattern rules to the id number, the number of possible id numbers comes to about 1 million (instead of 10^7; each field can have {0,1,2,3,4,5,6,7,8,9}=10 digits, so net combinations = 10*10*10*10*10*10*10).
Therefore, to completely automate this process I wrote a script which would generate an id number, submit the form with that id number, and parse the resulting HTML profile for the "flag". If the script finds a hit on the flag, it stores all the fields of that player in a database. This script is working absolutely fine but the speed I was getting was about one check per second which means that I would have to leave the script running for about 11 days (to process all of about 1 million checks).
So i came up with this idea to divide the check into ten parts and i created separate scripts for each part. Now basically the first script checks for the first 100 thousand combinations, the second checks for another 100 thousand combinations, and so on.
The problem is that I am able to get only two of these scripts running at the same time. So it would still take me at least 5 days to get all the results. The rest of the scripts just sit there in the server's backlog. This is definitely due to Apache's limitation to handle multiple processes. The server I am using to run this script as well the target webserver both run on Apache2. I am sure it's not a problem with the receiving server. It has to be my Apache web server which is running the scripts. I have tried using mpm_winnt (on a windows server) as well as the prefork and worker modules (on a linux server) without any luck. Has any of you ever faced the same situation?
For those concerned about the legitimacy of this work, rest assured, this is absolutely legit. There's nothing in the website's use policy which restricts somebody from doing this. Moreover, my client hired me to do this only because the website owners were not able to hand over the data he required. They gave the stupid reason that they are helpless in providing the data because they don't have a system in place which would allow them to do a search restriction!

I've been having trouble the past few days with someone who's been "attacking" my site so to speak by continuously downloading very large files with as many connections as (he) can open. I operate a large downloads site for computer games, this person has selected the largest files (like 400-500MB). Not sure of the real intent other than to clog up my bandwidth capacity. Also he appears to be using proxies since as soon as I ban one, another shows up seeminly from China.
Anyway, I have mod_bw and I've limited the number of connections in the downloads area to 2. While that works ok, his tool uses threads like a download manager would and he's using up 30-40 child threads for his 2 file downloads.
So 2 questions,
Is there anyway to not only limit file downloads to 2, but limit the number of connections per request? Many of my visitors do use download managers and I'd like for them to continue using them but use a reasonable number of threads like 6 or 8, but not 30.
Also, is there a way to restrict access to someone using a proxy?

I currently have 2 VPSs that I'm monitoring and I noticed that on one of them the memory usage is much higher than the other which doesn't make sense to me. I tracked the high memory usage to the Apache processes.
Here's the overview of the VPSs:
LiquidWeb VPS- 512MB RAM, 10 Sites with minimal usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 1.2 /usr/local/apache/bin/httpd -k start -DSSL
Virpus VPS- 384MB RAM, 61 sites with moderate usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 0.3 /usr/local/apache/bin/httpd -k start -DSSL
Both Apache configurations are identical, the only difference besides the hardware is that LiquidWeb runs CentOS4.7 and Virpus runs CentOS5.2, any ideas? It's not to big of a deal since I'm not near my limit for either of them but I was just curious.
tell me what the average usage of the CPU and RAM be from apache?
User 'Nobody' (Which I presume is apache) is using 13% CPU and 38.98% of RAM. Is this normal or is it well overloaded?
I've hired *name* to take care of my server, but it's just getting so frustrating, as it seems they can't fix my server/optimize it correctly.
I just want some input as to what the problem is here.
I got them to install lighttpd along with xcache.
After about 15-18 hours, the server's CPU slowly increases to be using 90-90%, giving me the 500 Internal Server Error.
I've asked them to optimize xcache and lighttpd, but I keep getting these responses:
Quote:
The should be pretty optimized. Xcache has limited optimization features.
Quote:
Lighttpd itself is pretty optimized, the problem is php. Php runs as its own binary and theres not many parameters that can be tweaked.
Is that even correct?
-------------------------
So I got them to enable apache, and disable lighttpd.
This time, it's the other way around.
My ram get's completely used up, forcing the server to use Swap; making the load shoot to 50+. CPU usage is fine the entire way.
-------------------------
This has been going back and forth, enabling/disabling lighttpd and re-enabling apache but a problem always comes up each time.
Am I asking for too much?

I'm running a single Magento website with only around 150 products, and very low traffic, on a VPS with 2 Cores and 4GB of ram. However I am getting constant warning emails about high Apache Memory usage and High CPU usage.
The server and site were working fine, however since the server failed (Power cut on upgrade at the hosts end) and we rebuilt the website I'm getting these warnings, my host said it is just the website and the server needed upgrading... to which I did (server was a 1 core 2GB ram server). However since I've upgraded I'm still getting these warning emails.
