I'm running XAMPP on my windows machine and experiencing a problem with Apache crashing a couple times a day. When it does, a dialog pops up and I have to manually tell windows to end the program. After I do that, XAMPP automatically starts it back up in a couple of seconds with no issues. When it crashes while I'm not home though, the server is down until I get back. So I have two questions:
Are periodic crashes something that should be expected, or is this indicative of another issue I should be trying to pinpoint?
If this is something I should just learn to deal with, is there a way to automatically restart httpd.exe when these issues occur, so I don't experience down time when I'm away from home?
You'd look into log files, especially the Apache access and error logs, to see what happened, when you are not at home. I've met some similar situation: I have a problematic PHP script hosted on my server, when someone visits the page, it leads to an Apache crash.
I'd suggest you do the investigation as follows:
Search the timestamp of recent Apache restart.
Check the Apache access log to see whether there are some scripts have been accessed.
Manually access these scripts in your browser (to see if Apache will crash again)
You'd better check the PHP error log as well.
If there is really nothing suspicious, you can try WAMP bundle alternatively, which is also a very popular PHP development environment and it is stable.
Although there aren't many cases in which one should "expect" periodic crashes, in this case you are better of reconsidering your setup. From the frontpage of the XAMPP site:
XAMPP is the most popular PHP development environment
Sure, you can use it as "production" server, but XAMPP isn't build for hosting websites, it is intended as development server, so you don't have to manually setup Apache, PHP and MySQL on you dev machine. If you actually want to run your website for the public, setup Apache/IIS, MySQL and PHP manually, those products on there own are made for running in production. Or you can consider getting some cheap shared hosting somewhere, so you don't need to setup anything.

I could ping my websites but I got a 404 going there.
My server was running normally, no new mail for root.
Is there a service to alert you when your websites are down ?
What do you usually do to understand why it's down?
I took a look at the apache2/error.log and saw that it couldn't access one of the website I had deleted a few hours ago. I just did a a2dissite and restarted and it was fixed, I could access my websites.
I either got lucky or I postponed a problem. Any idea what I should do next to make sure everything is alright? (I'm on debian by the way)
I am using Apache Tomcat 6.0.18, I am running on Windows XP
I have a web application which I place it's war file under webapps folder. The web application runs fine, its just when I run the shutdown.bat the application still runs (as in I refresh the page and it doesn't come up not found).
I check the localhost:/8080 and webpage cannot be found comes up
but when I run localhost:/8080/myapp my application comes up.
I have tried this in both IE and Firefox
Thank you for any help.
I had this similar problem, This can only happen if Apache Tomcat is not configured properly. Best way is to check build path and look for exact directory of Apache.
Example
i.e C:\Program Files (x86)\apache-tomcat-7.0.27
Also look for windows service for start, restart or stop
Run - services.msc
You may want to check this link
i.e
Verify that tomcat is actually down (simplest way is via task manager)
The issue sounds like a caching issue. Try deleting your cache.
I finished coding my website for awhile and would like to stop Apache from starting when my computer boots because it slows down my other startup applications. I have looked through the Apache Wiki, the source files, and the htaccess file. Maybe I am not finding it, but is there any way to do this without uninstalling Apache?
I am using Windows 7 as an OS.
*I just want to mention that this is different than simply stopping or starting or restarting Apache. I know how to do that. I would just like it not to start up on boot until I start working on my website again.
Thanks
Open msconfig (start->type "msconfig"->click "msconfig.exe")
Check "Startup" tab for Apache or "Services" tab if you can't find it, and disable it.
I'm hosting my website www.xgclan.com with the latest apache 2.4.1 and sometimes my server gets jammed, it doesn't seem to send any data but you don't get a timeout like when the Apache process isn't running.
A reboot of the process resolves this issue.
It seems to happen when you open the website in multiple browsers on the same system.
I've tested it on 2 different systems to make sure its not a bandwith or cpu problem.
Putting this without the quotes "AcceptFilter http none" in the httpd.conf fixed the issue for me.
I found the solution here: http://www.apachelounge.com/viewtopic.php?t=4543&postdays=0&postorder=asc&start=20
So I have several dedicated servers out there running Ubuntu Lucid server. They primarily run WordPress sites - LAMP. However, one of my original sites is a controls engineering site that uses MathTex to render the equations.
MathTex is pretty hard on servers. The engineering site is still hosted on the original VPS which runs something like CentOS (but that's irrelevant). The traffic and numbers of renderings that MathTex creates cause resource issues with my VPS. I've been able to allocate more resources to the VPS but ultimately this gets expensive. So I'd like to offload the equation rendering to my dedicated servers all of which are much more powerful and under-utilized.
So I've followed the instructions on installing and compiling MathTex. And MathTex works fine from the command line. However, when I attempt to call the script via my browser the browsers all try download the cgi file (I've tested on Firefox and Chrome on 2 machines).
This led me to attempt to compile and install on my home Ubuntu box that is Ubuntu desktop. The command line works fine. However, again when calling the function in my browser it wanted to download the file instead of rendering an equation. So I moved the mathtex.cgi script to /usr/lib/cgi-bin. Still no go. Then I changed /usr/lib/cgi-bin to 777 and it worked. I changed /usr/lib/cgi-bin to 755 and it stopped working.
So my home box works when /usr/lib/cgi-bin is 777. I tried that one of my dedicated Ubuntu servers and still no go. My browser still attempts to download the file.
The directive for Apache to find the cgi-bin directory is in /etc/apache/site-available/default. And at a quick glance they appear to be identical (I haven't yet studied every character).
FYI
I got some help from my hosting company. They are generally pretty good but this is outside the scope of what they provide for free. So when I was switching servers I had a couple of password issues and managed to tack this question on as well.
The support person finally got the mathtex.cgi script to run by creating a /cgi-bin under the domain's folder. Making that folder 777 and adding an AddHandler cgi-script to the http.conf. Then he restarted Apache2.
I had been putting mathtex.cgi under a generic /cgi-bin directory that I had intended to share among all the domains as needed. And this generic /cgi-bin directory appeared to be what the MathTex installation instructions were suggesting.
Hope this helps someone else.
