Server :: Apache Simultaneous Requests Time Out While PHP Script Is Running?
Apr 1, 2011
On my server I provide OCR file conversion service but the problem is when a user uploads a file and it's being converted then if you open another tab and try to load the site it won't respond until that conversion is completed. In other words until the PHP script finishes execution apace doesn't serve any other request to the same browser.
Here is my apache configuration:
Code:
ServerTokens OS
ServerRoot "/etc/httpd"
PidFile run/httpd.pid
[code]....
You can check what I mean if you try to upload and convert a file and while the file is converting try opening the site in another tab.
I'm working on a thorny mod_rewrite problem. I have a mac connected to my LAN running MAMP (Mac/Apache/MySQL/PHP). I request a non-existent file:
Code: http://192.168.1.2:8888/careers/db/1.html I see this in the mod_rewrite log file:
Code: 192.168.1.102 - - [14/Nov/2009:13:46:07 --0800] [192.168.1.2/sid#807df8][rid#8ec850/initial] (2) init rewrite engine with requested uri /careers/db/1.html 192.168.1.102 - - [14/Nov/2009:13:46:07 --0800] [192.168.1.2/sid#807df8][rid#8ec850/initial] (1) pass through /careers/db/1.html Note that the requested uri is /careers/db/1.html
If I change just the file extension on my request to PHP like so:
Code: [URL]
Then the request uri is totally different now. Here's the rewrite log:
Code: 192.168.1.102 - - [14/Nov/2009:13:47:23 --0800] [192.168.1.2/sid#807df8][rid#8fc850/initial] (2) init rewrite engine with requested uri /Applications/MAMP/htdocs/careers/ 192.168.1.102 - - [14/Nov/2009:13:47:23 --0800] [192.168.1.2/sid#807df8][rid#8fc850/initial] (1) pass through /Applications/MAMP/htdocs/careers/ Note that the requested uri now has a full path which does not include the actual filename, /Applications/MAMP/htdocs/careers/
What the heck? More info. If I request [URL], I can actually access p1.php. The requested uri is /careers/db/p1.php. The problem appears to be because the filename starts with a number. I can also request [URL] and get thru to 1.php with requested uri /careers/db//1.php. Does mod_rewrite think /1 refers to a backreference or something? Why can apache handle the html file request properly and not the php file request?
I've had a VPS running Ubuntu 9.10 x64 server, hosting 3 websites of mine for a few months now. This problem has been happening for a while. Every once in a while, probably every 2 or 3 days, I'll wake up in the morning, and apache won't be responding, no web pages will load. /etc/init.d/apache2 status, reports that apache is functioning properly. Every time I simply have to restart the daemon and things run fine for another few days.
I thought maybe it was a memory issue, so I lowered the MaxClients in the prefork module from 50 to 30 a few days ago, but the same thing is still happening. My VPS has 512MB of ram, burstable to 1GB, and according to Virtuozzo, there was only one night of high traffic where I even came close to that soft limit. I've checked my syslog, and there's absolutely nothing in there about apache. I've checked apache's error.log as well, and there's nothing in there that would indicate a problem either.
A Linux (CentOS5.3) server is setup with apache reverse proxy. The reverse proxy server is opened to outside and an internal server is mapped to ProxyPass configuration. SSL certificate is also installed on the Apache reverse proxy server. The problem is, it is extremely slow in serving http requests through reverse proxy. There is no problem with server resources or bandwidth. When the internal server is directly accessed through Internet, there is no delay. The backend server and the reverse proxy server are also on the same switch (same subnet). When I searched the Net, there were recommendations to enable cache in Apache. I did so as follows in httpd.conf.
But still there is no progress. Do I want to enable cache in ssl.conf too? Or is there any other workaround to speed up Apache reverse proxy. Is there a way to check that caching is happening?
I run a small home server (Debian 4), which acts as my gateway to the internet (ie, firewall) and runs a web server, dhcp, dns, and acts as a file server to the rest of the machines on my home network. Now I know it's never a smart idea to have all those services running on the same machine that is acting as a firewall, but I don't fancy running multiple servers just for home use, as it's mainly allowing me to learn system administration.
I noticed a few days ago that my internet had become unbearably slow, to the point where I could sometimes not load web pages. I spent a while searching through log files on my gateway, to try and find out what was eating up all of my bandwidth. When I came to apache's access.log file, I was confronted with this:
Multiple requests to my server, for totally random websites. I didn't even know it was possible to make those types of queries to a webserver. The only thing that is on the web server is a browser based torrent client. I have only shown a small snippet of the log file, but there are around 90k lines to different web addresses, from many different IPs. What I want to know, is what is happening? :S Why is someone querying MY web server, for web sites totally unrelated to it? And most of all, how can I stop it. My initial was to try and use iptables to block multiple requests from the same ip within a certain time frame, which I think would work as the server shouldn't really get many queries from external networks.
I have recently ported from Windows to Linux (xubuntu) I am a developer, i installed everything i need, LAMP. Now in Windows i used to turn off all unnecessary Services, i don't need the Apache or MySQL service running all the time. I used: net start mysql
Whenever i needed it. How do i do the same in Linux: 1. Disabling not-needed daemons from auto-starting? 2. Starting them only when i need them?
We just setup a Moodle server in Apache. We would like to track how close (if at all) we are getting to our MaxClients limit. Is there a log that will show simultaneous connections?If there is, can it be set to only log when specific numbers are hit?
Question 1: Hey. I noticed i have quite a few logs that end with .[number] for example "syslog.1" "mail.info.1" etc, why is this and why are they there since almost nothing is logged in them ??
Question 2: on my server im running a script like imagebam and imageshack with hosts images so i have quite a few apache requests to my server. I am wonder why apache takes up so much CPU for some of the requests ? in Htop some requests take up 1.2% CPU while other take up 3-5% etc, so the total load is about 1.50 0.58 0.84 to 2.61 1.08 1.14 with about 128-150 apache requests all the time while sometimes the CPU load can be almost 0 with the same ammount of requests. is this normal? what could cause this in apache ?? the server is just running apache2. MYSQL is running on another server.
I've been scouring the message boards and trying different things for two days and haven't found a solution. I set up Ubuntu 10.04.1 a few days ago using the server iso and selected the LAMP installation option. I will be using it as a sandbox to try out things from a PHP/MySQL book I purchased.
I have installed Gnome since sometimes I just can't get the command prompt to let me do things and Gnome may at least tell me why. I also installed PHPMyadmin.
My problem is that I can work with this thing all I want in any way I want - HTTP, SSH, SFTP, etc. - from within my home network but Apache refuses to respond to an outside request. Since it's only a test box it usually wouldn't be that big of a deal but I am going out of town for a couple of days and would really like to start working with my new book.
I am 99% sure my ISP is not blocking any ports. I have a ComTrend ADSL modem with router. I have given my Apache server a static IP on the NAT (xxx.xxx.x.101) and set up a dyndns address so I don't have to keep remembering the IP address.
Here is what I have tried so far: Setup a virtual server (port forwarding) on the router to to direct traffic on port 80 to internal IP .101The router told me its interface is using 80 so it would move itself to 8080 Made sure to also add port trigger for port 80 Made sure to save/reset the router Used my iPhone to connect via 3G - didn't work using IP or dyndns name Used iPhone to connect to 8080 and router responded
Set port forwarding/triggering for 8080 -> 80. No joy there, either Tried changing listening port to 8000Set port forwarding and triggering to allow port 8000 Changed ports.conf to read NameVirtualHost *:8000 and Listen 8000 Changed first line of /etc/apache2/sites-enabled/000-default to <VirtualHost *:8000> Restarted Apache service
Apache responded to dyndns.com:8000 from home machine No response when trying same on iPhone (sorry, it's the easiest way for me to test from outside my home network)
At one point, I added "ServerName localhost" to the otherwise empty httpd.conf file but that didn't seem to do a darn thing.
Many of the posts I have perused are at least a couple of years old and have included information on taking action with files that are not there or are no longer where they were. I have interpolated where I can but so far nothing has worked.
my server into the public internet and must have my webserver [2.2.9 (Debian)] act secure. But this does not look very easy [I am searching, reading and working on it already the whole day ]. I read the apache docs, but there is a lot of stuff, which is different in Debian [lenny, 5.0.6]. Apache ignores the host-header given by the browser: [URL] are all served, but should be blocked. I new new to apachy, but on my IIS this works as expected. All browsers act equal [so no browser header problem].I configured two VirtualHosts, an excerpt:
The I go to my hosts file on any box, and add hugo's ip-address under the new name x. Then, x is served, although the host-header in apache Every user coming from the internet could make the same!
I noticed i have quite a few logs that end with .[number] for example "syslog.1" "mail.info.1" etc, why is this and why are they there since almost nothing is logged in them ??

I'm trying to figure out how I can get a request count per CIDR/24 from an apache log in combined format - e.g.: Code: 24.147.44.122 - frank [10/Oct/2011:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326 "[URL] "Mozilla/4.08 [en] (Win98; I ;Nav)"
I'm stuck using BASH for this and I generally write everything in Python, or even Perl if necessary so BASH isn't the most comfortable for me. I've got enough to extract the IPs and get a count I just need a slick way to come up with a sum on a per CIDR basis.
I'm running wordpress and have gone to the painstaking effort of setting up the ftp server on my 5.3 machine so it can do its own updates and download plugins. However, I've found that if I try to download anything, I get a "unable to resolve host..." error from the script. If I watch Iptraf while making the request, I see all the port 53 requests going to 127.0.0.1. Pings are too.
However, if I ssh in, I can ping and wget and whatever I want all day long and all the DNS requests to go the router (Clarkconnect 3.2 gateway machine). The web browser in the terminal works fine too. What is it about the php scripts that is causing them to misdirect pings and dns requests? I've never seen anything like it and can't find anything on the web about it either.
Is there a way of altering the time between password requests. For example after I login there seems to be a certain amount of time before the screen blanks out and a new request for the user password is asked. I would like to increase the time substantially.
We have a production web site running apache 2.2.3 across several web servers. we also have a major problem with SPAM comments right now. our method of identifying valid IPs (whether by external clients/customers, or internal personnel) vs SPAM'ers is not ideal - its prone to erroneously labeling legit IP's as targets to be blacklisted.
What we need is.. a way to see how much distinct request traffic is coming from any given IP address to the site in real time (or very near realtime). Essentially we want to see in some graphic/chart way requests per sec to apache / per ip sorted by requests per sec.Would nTop do this? I've only used this in a limited form at a branch office, not on a production web server.
I have a single CentOS server with two separate NIC's. I was asked to install an internal Wiki on Apache but have that dedicated to one NIC so it's internal only. Then have just a site running on Apache on the 2nd NIC which is externally accessible. I have never done anything like this and would like tonow how difficult this would be on a single stand alone server that I have above?
When I do " ps aux | grep apache " I can see that apache2 is running. But when I do the same thing for http or httpd there is nothing. I looked for this question in the forums but couldn't find it. I probably don't know just what to look for.I'm using the new Debian Squeeze, and was fooling around heavily with new software installations and modifications, and just noticed all of a sudden that I couldn't get on the internet - so I know I did something but don't know what.I can plug in a thumb drive with a bitnami joomla stack on it and run, " ~/tmp/joomla-1.6.0-0/./ctlscript.sh start "and that gets things going for the joomla stuff (apache, http, mysql, php), but that stuff is pretty self contained and does not effect the browser's attempt to reach the web.
I just did a fresh install of ubuntu 9.10 and install apache2 webserver with php5 and mysql, but for some reason I have no idea why but when upload files to the computer running apache2 webserver
http://69.242.228.170/ is the link to the ubuntu system It's not displaying the website correctly and it's not working on any pc on my network either, but it looks fine in dreamweaver when I was designing it on my laptop. list of all the files and folders in the /var/www path
i have apache and mysql running, i can access my web server by visiting localhost on port 80 but for some reason when it doesnt work when i try using my ISP provided IP address... (it used to work).. i have my router setup with a DMZ on my LAN IP (my computers IP, this is the computer in my home network that serving with apache).. i also cant seem to shut down my mysql server (theres an update ive been trying to get) even when i use sudo...
I'm trying to modify an existing user so that any files they create can be at least read (although writing and execution would be nice) by any other user. The reason is because I need the daemon running my Apache server to be able to access files created by a daemon running under this user, files which will be created and accessed in real-time.
I set up my first web server and it works flawlessly -when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.
I have two network interfaces on my server, eth0 (public static IP connected to internet directly) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1. It is connected directly to the internet and serves as a SNAT for other comps on the lan.I added "192.168.1.1 www_server_com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.HOwever, the server itself only opens website if the address islhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www_server_com ( I cant use dots as I do not have more than 15 posts on the forum )Here is the firewall script I am using.
I am running Apache 2.2.3 on a CentOS release 5.3 (Final) with 100 Sites. I've notice that Apache is making my server Swap around 200 MBs. "http://www.xxx.yyy.zzz/server-status" doesn't show me too much to, so I am looking the behavior of specific httpd process. ProcessID "18753" is the one for "http://www.xxx.yyy.zzz/server-status" in my browser.
This command show me (In KBs) how much virtual memory is that specific process using: # /etc/init.d/httpd start # grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }' 3012 ... Running this command a lot of times it gives me the same output, but suddenly... # grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }' 21708
Something make that process (and all the others httpd process too) to use a lot more memory!
Part of my httpd.conf: # Timeout 120 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 3
My server is running Mysql 5.1.34, vsftpd 2.0.5, BIND 9.3.4-P1 (as slave). I couldn't found anything running in the specific time that httpd processes start to use that much memory.
I trashed my Karmic Ubuntu install and installed Lucid (I had heard that the boot times were much reduced and I didn't see any improvement in my normal upgrade). I reinstalled Drupal but find that my installation of Apache does not run the scripts, but rather passes the php text file to the browser. IIRC when I installed it apt configured Apache correctly without me having to edit .htaccess or /etc/apache2/httpd.conf which makes me think that I am missing a key dependency.
Does anyone know of a check list to which I can refer to make sure that I've installed everything? My installation has Postgres instead of MySQL. Failing which, in the event that my memory is faulty, where can I find which changes need to be applied to the configuration files above?
OS: Ubuntu Server x64 10.04 Apache: 2.2.14-5ubuntu8.4 I have a virtual server which has been running for months with no problems then one day I saw that it crashed and I had to power cycle it. Since then I have been unable to start Apache as it segfaults no matter options I give it. Before I try to reinstall Apache, why is this segfaulting?
Code: execve("/usr/sbin/apache2", ["/usr/sbin/apache2"], [/* 21 vars */]) = 0 brk(0) = 0x7f9f48f8d000 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory) mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f9f47e0d000 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY) = 3
I'm trying to get Apache to run in a user's home directory. I changed the conf file so that Apache runs under the user and group "kiosk" and changed the DocumentRoot and Directory from the default to "/home/kiosk". Then I set Apache to start at boot (chkconfig --level 235 httpd on) and rebooted. When I checked, httpd is running as kiosk like it should (ps aux | grep httpd). However, when I try wget localhost, I get a 403 response back. If as root I call "httpd -k stop" and then "httpd -k start", then everything works exactly as it should (curiously, if I try using "-k restart", it still doesn't work). After this, httpd still shows as running as kiosk and if I check before calling start, it shows no httpd processes running as expected.
This only happens when I use httpd to stop and then start the web server. If I try to restart using apachectl I still get a 403 error. As an interesting aside, after I've used httpd, if I try using "apachectl restart" I get a "(13)Permission denied: Error retrieving pid file run/httpd.pid" error. This is all on a freshly installed CentOS 5.5 server. Why I'm seeing this very different behaviour from what I thought were just equivalent ways of starting Apache? And then what I could do to get it to start up and run properly on boot? One last item to mention is this isn't a permissions problem. I set the permissions to 777 to both the home and kiosk directories (and 666 to the web files) just to be sure that's not the problem.
I am having a problem.I use Ubuntu 10.04 server edition.Two computers on LAN one with Public Ip A other with local (Class C IP)say it BWith a third computer in same subnet I can access a TomCat application running on B as http://Ip of B:8080/applicationI want to use A as a Reverse Proxy for this application to be reachable from internet.So on Googling I came across some thing known as mod_ajp I enabled that on my Server A asa2enmod proxya2enmod proxy_ajpa2enmod headersbut after that I am not able to understand as how do I define vhost to be able to forward HTTP request which come on A as www.myserver.com/appto B which I can see internally as http://Ip of B:8080/application so Tomcat on B handles this.
