i have a problem with my server it is a Xeon with 2Gb ram, i have a igh swap usage and when it reach the size of 4gb that i have set it go in kernel panic, this is the actual value
I have a linux server that is only hosting one site , and although the httpd and mysql are working well , then the server load is high and when I restart the server the server load is high till the swap accelerates to 100% and then it uses the memory alot.
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ? Question 2 : Why i don't find high usage process in top command ? Question 3 How can i resolve this problem ?
I'm having an issue with what I believe is Apache. Things will be running nicely, then all of a sudden things will just 'blow up'. Apache seems to fork a bunch of new processes, and it starts ripping into the memory. I've had it essentially eat through all the free memory and swap, and the system will then freeze up as there's no more memory. This is a CentOS server running CPanel, the configuration had been up and running for a long time without problems then this suddenly started happening.
my php.ini had some changes (/etc/php.ini). Today i have switch from apache to lighttpd, do i need to edit another php.ini file ? Apache and lighttpd use the same php.ini ( /etc/php.ini)?
Until recently, it seemed like everything I read about a server indicated that Apache was king. I have never read anything that has given me any reason not to use Apache.
However, about a year ago when I discovered Django, I discovered Lighttpd. From everything I've been able to read, Lighttpd seems to be a better web server, but still don't know very much at all about Lighttpd.
I'm fairly comfortable with Apache, although I've never cared much for it. I have a feeling that I'll like Lighttpd quite a bit more from the very little that I do know about it. I'm wondering if I should even consider switching.
For one, it seems that everyone knows how to work with Apache and Lighttpd seems to be far less common. Apache also seems to be much more established which leads me to believe that it's a safer choice. Nonetheless, I still really want to give Lighttpd a shot. And, judging from what I've seen about Django and Lighttpd, Lighttpd seems to be a better choice when working with Django.
What do you think? Should I stick with Apache since I already know how to use it? Is Lighttpd worth the time to learn or is Apache just too good?
I wanted to know what do you prefer as server apache or lighttpd , though I am running lighttpd and have no issue except that there is too much work for mod rewrite and it effects search engine, so I was thinking to use apache instaed of it will it be possible to install apache over lighttpd or will I have to go for fresh install.
For a year now I've been running my server with Lighttpd. It's worked out well so far, but now that I have a new box I'm reconsidering.
Lighttpd does not support .htaccess files which is a bit of a pain, and doesn't have the same support by apps like Apache does. Given that I get very little traffic to my box (it sits idle most of the time) I am considering Apache.
How is security between Apache and Lighttpd? I know Apache has things like mod_security and mod_evasive, but I've never really checked how Lighttpd compared.
We've been thinking about writing our own hosting control panel for our own "tight" hosting setup, so that can alter the panel just to our needs without relying on updates from anybody else.
To read new configurations in Lighttpd or Apache, as far as I know, requires the software to be restarted (for example service apache restart). Are there any negative effects of this, I'm assuming that whilst being restarted there is a small amount of time during which the software is "down" and websites can't be accessed during that period (probably <1 second). Am I correct?
What is the best way to reload configurations into these http servers without service interruption? I notice that DirectAdmin seems to just restart Apache on any function that alters the configuration file - for example adding a new user.
index-file.names = ( "index.php", "index.html", "index.htm", "default.htm" ) and my httpd.conf
Code: ProxyRequests Off ProxyPreserveHost On ProxyPass /lighttpd http://0.0.0.0:81/ ProxyPassReverse / http://0.0.0.0:81/ Now when I created a folder on my server's httpdocs /lighttpd/
everything runs smooth so I got the lighty to work for me.
Okay now that i figure it works I wanted to run one of my subdomain on lighty so that I can reduce the load on the server. Does anyone know how I can setup one of my subdomain to open with lighttpd and keep everything else on apache?
Has anyone done this or currently running this setup? to try it with my directadmin server first but havent found very good documentation or howtos. Ive looked the last week or so and havent really found anything helpful. So if anyone is running such a setup Id like to know how you did it and how much better if any it is.
How do I configure Lighttpd to serve images/javascript/css files that are littered about my websites? Can I just input the paths of all the directories that I want Lighttpd to serve from?
For example, I have 4 separate websites with each having a message board, main page etc... Could I have lighty serve the files from:
I'm running both Apache (on port 81) and Lighttpd (port 80) on my VPS. I would like to have Apache run CGI/Perl scripts only for virtual hosts in the Lighttpd.conf. My Lighttpd.conf already has fastCGI enabled though.
There are 2 different domains with the same IP being served by Apache. I want one of the domains to be served by lighttpd, is it possible without having to change the IP of that domain?
somebody know is possible on some way route traffic before come to web server (apache or lighttpd)?
I want to setup lighttpd on port 80 and apache on port 81 and I want visitors to go direct to apache or lighttpd without url:81 and that must work on this way if somebody visiting url1.domain.com that go to lighttpd on port 80 and if somebody visiting url2.domain.com that go to apache on port 81 and something must route it before lighttpd and apache (and get/post must work), is this possible on some way?
I know that lighttpd and apache can do it but I don`t need it on that way!
I 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.

Idle CPU usage usually goes anywhere from 30%-0%. Is there any way to limit apache from using more than 75% cpu, or any other ways to drop cpu usage?
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?
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.
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.
I'm really new to VPS's and plesk so I'm wondering what I can do to try and track down what is causing these high usage as I'm 100% certain the site was fine before. The server has default build both before and after the fail.
We are currently running plesk 11.5 and over the last few months, the apache memory usage has been very high. On investigation we have gone through the logs and we can't find a cause.
I can issue a service httpd restart and the memory drops for about 30 minutes and then we see the apache memory grow to almost 1.5 - 2GB. Why this keeps happening?
