Server :: Using Apache2 Prefork As Proxy (mod_proxy)?
Mar 9, 2010
i'm using apache2 prefork as proxy (mod_proxy) and i'm facing some performance problems such freezes , for instance the entire server blocks and becomes totally unresponsive after several requests.
at first i thought that the system is running out of memory so i tweaked the mpm config and reduced the number of allowed processes that can start concurrently , however the problem still persists..would mpm worker serve better than prefork ?

I have a php app set up in the default virtualhost, and want to add a Grails app. The grails app runs on [URL] and I want to configure apache2 to proxy that folder to Jetty using mod_proxy.
Module is enabled
Code:
$ sudo a2enmod proxy
Module proxy already enabled
[code]....
Quote:
[Sun Mar 21 00:14:56 2010] [warn] proxy: No protocol handler was valid for the URL /mailscan. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule. My apache2.conf contains no LoadModule lines, and a2enmod says it's already enabled. Does Ubuntu Desktop (Karmic) use the DSO versions of modules, or did I miss something else? I'm aware I should also use mod_proxy_html to make sure only the "portless" version of the address is outputted, but I can fix that later!

I seem to be having a problem with mod_proxy and https websites. A simple connection to port 80 works fine but all calls to 443 fail.
I had a look at my firewall but can't see anything that would block port 443, although I get no tcpdump traffic on that port on the deb01 client when I try and connect to it. I disabled the firewall but still no luck.
My configuration consists of 3 VMs (KVM) each running a different website.
I get the following error when connecting to ssl deb01
Code: An error occurred during a connection to deb03.example.com.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
The following is what can be found on the host
Code:

Dom0 is having public IP. I read a lot of blog and tutorials about name based and IP based hostings and also about mod_proxy. But I am unable to do.
Here is what I am trying to do. I have a webserver on public IP.Which is running Xen on it. There are 4 Guest Operating systems installed on top of Dom0 which are Dom1,Dom2,Dom3,Dom4 These are application servers which are going to serve the requests that come from the main server.Which is Dom0.
All I see is "It works" on all 4 of the hosts. On my LAN on any machine on same subnet if I do [url] of Domu1 message comes
Code:
in browser from LAN gives me a message
Code: It works.
What do I need to do on Dom0 so that requests are forwarded to the appropriate DomUs apache2 is running on all of them including Dom0.Some one suggested me to go for ReverseProxy in Apache2.

I have a server acting as a proxy to a couple of IP cameras on my local network. The IP cameras require HTTP-Authentication (Basic) but I want the outward facing Apache server to automatically log in without prompting the user for a login.
My current configuration is:
Code:
That works as a proxy but still asks for a HTTP Auth login. Can I get Apache to pass the login details to the IP cameras so users can just hit up the proxy and view the camera without having to log in?

I'm working on setting up a hosted OSS app on a VPS and have a question about doing some proxying. I have Centos 5.5/Apache 2.2 running on 2 VPS's, in different locations, accessible from the net. One of these hosts the app itself, the other will be used as a web portal where the end user will login to auth and then be able to access the app. Now, since I don't wan't access to the app server from the world at large, I want to firewall it and only allow access from the portal machine. So what I think I need to do is set up a reverse proxy with mod_proxy, and then if the end user auths forward them to a specific url on the app server.
So when they connect to [url] and log in I need them to be redirected to app.machine.com/theirdir
So the questions I have are:
1) Can this be done? If so, is mod_proxy the way to do it? Configuring Apache isnt a problem, but I havent worked with mod_proxy.
2) If this does work, will it also work with SSL?
3) I've seen a few small tutorials on the net, but not doing exactly what I want to. They all use the reverse proxy with a public IP connecting to a server with a private IP behind a firewall, while I have public IP's on both ends. From a network standpoint I know this shouldn't matter, but I'm not familiar with mod_proxy's particulars itself.

I have a webserver apache2 on debian Lenny. I am using gateway as Dom0 and rest of the operating systems are different Dom's .Using a xen virtualization setup.
I want to have a few websites
http://site1.myserver.com
http://myserver.com
and http://myserver.com/site2
I did set up a reverse proxy environment for doing this.
Code:
Dom0 LAN IP ----> 192.168.1.1 Gateway (where reverse proxy is set)
DomU1 LAN IP ----> 192.168.1.13 (here myserver.com and site1.myserver.com both are hosted.)
Domu2 LAN IP ----> 192.168.1.17 myserver.com/site2 is here.
Configuration on Dom0 of sites site1.myserver.com and myserver.com
Virtual Host Configurations on Dom0 in /etc/apache2/sites-enabled/myserver.com (on gateway)
Code:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName myserver.com
ProxyRequests off
<Proxy *>
Order deny,allow

A first server with apache2 installed and configured as reverse proxy, that works great, with this version:
That works mostly, but fail with an oma (outlook mobile access) redirection
It works for all reverse sites hosted, but when we try to connect to oma using a nokia phone, it fails.
I can see in access.log that it hangs on FolderSync istance.
I've used wireshark to sniff packets, and in oma server I can see only three way handshaking coming...
My doubt is: when I'll upgrade working server, also it will not work anymore...
Configurations are the same (I've copied /etc/apache2 folder from running one to new one).

I have figured out how to use virtualhost, proxypass and proxypassreverse. So far, so good.
The problem I'm experiencing is this:
I have a reverse proxy server running apache (123.123.123.123)
Behind this proxy server I have a http server running apache (124.124.124.124).
This http server has multiple sites (virtualhost), it's only reachable via the proxy server.
If i run a nslookup on www.somedomain.com I get 123.123.123.123 (Not really but you understand what I mean)
I put my proxy to have the IP 123.123.123.123, so far so good. The requests come in to the proxy server.
I want my http server to be named 124.124.124.124.
In the http server I wish to set up my virtualhosts like this:
How do I get my proxy to grab the data from the http server?
If I do like this I will only make another request to my proxy server.
If I do like this, only the first page in the httpd.conf in my http server will work.
Do I need to setup a different DNS server for the proxy server? I would hate that. Perhaps use hosts-file in proxy. Or maybe I can use sub-domains?

I'm using CentOS 5 and just found out that there are people using my Apache Web Server as proxy (version 2.2.3 the OS's default).
I've checked out that my mod_proxy is already disabled but the unauthorized incoming request is still very large.
So I tried to compile an Apache from raw (2.2.17) just enabling mod_rewrite and then found out that the 'proxy' request is still there.
Tried httpd -l and here are the modules inside the Apache :
Code:
# /opt/apachew/bin/httpd -l
Compiled in modules:
core.c
mod_authn_file.c
[Code]....
There should be no mod_proxy but why should it still accepting proxy request? I checked the access_log file and still found [URL] and so on.
My question is : - How to block all the proxy request and only accepting the normal web server request? I also have tried to enable proxy in the previous Apache and then setting up "ProxyRequest Off" and Proxy * only from localhost but the request is still there.
I tried by myself using the webserver as proxy in browser and all the URLs I opened including the false URL will be redirected to my index.php and this should show me that 'you-can't-use-this-as-proxy-anymore' right?
Insane people still believe they could use my server and they keep trying and trying.
I couldn't block the IP addresses because some of them are using the mobile data (GPRS/UMTS) and that is our market for the website.

I have just been told that httpd was not running on my Centos virtual server. It seems that my hosting company rebooted my server 2 days ago and that httpd restart failed due to:
Starting httpd: httpd:
Syntax error on line 213 of /etc/httpd/conf/httpd.conf:
Syntax error on line 2 of /etc/httpd/conf.d/proxy_ajp.conf:
Cannot load /etc/httpd/modules/mod_proxy_ajp.so into server: /etc/httpd/modules/mod_proxy_ajp.so: undefined symbol: proxy_module
I had worked around and forgotten about this some time ago. The problem arose because the most recent httpd update installed proxy_ajp.conf into /etc/httpd/conf.d which was then loaded on restart The trouble is I do not use mod_proxy (I think just to try and get a lean and mean web server) and proxy_ajp.conf does not check if mod_proxy is loaded before it tries to LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
Hence httpd fails to restart. RedHats's bug tracker lists this as an old issue (which was never resolved) [URL] My workaround was to rename proxy_ajp.conf to proxy_ajp.conf.orig so that httpd would start up correctly. However any updates simply reinstall proxy_ajp.conf and so IMO the problem needs to be resolved at source. how to ensure that httpd updates do not bite me in the future? Do I really have to run mod_proxy whether or not I need it?

I am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so

I have a proxy with SSL that forward any request to a backend platform. In this moment I have a problem if I'm trying to execute an activex on the backend platform. I'm reading that the mod_proxy blocks any activex request because it don't trust for the system. How I can do? I'm reading about mod_security.

I'm running 10.04 with Apache2/PHP5.x I wanted to test some basic cgi scripts, but my browser is displaying the code (#!...) If I run the scripts on the console, they work fine so CGI is not the problem, it's apache. To install the CGI module I ran sudo apt-get install libapache2-mod-perl2 with no problems. By the way, I installed Apache through apt-get instead of doing it manually, but it seems that the installation divides the conf file in different parts, so the regular apache2.conf has this:
Code:
# Include module configuration:
Include /etc/apache2/mods-enabled/*.load
Include /etc/apache2/mods-enabled/*.conf
# Include all the user configurations:
Include /etc/apache2/httpd.conf
# Include ports listing
Include /etc/apache2/ports.conf
[Code]....
I can't figure out what I need to do to get CGI working on my server.

I am having some problems after installing apache2-mpm-itk on my Debian 5.4 server. From my understanding apache2-mpm-itk will run child processes as root until a http request is received. It then suid's to the username in the VirtualHost directive. This is all working fine, as I can see a few apache processes started by a specific user.
However, the problem is when I try to restart apache. It will kill all the processes running by root but wont kill any of the processes that have been suid'ed to another username.
When i attempt to restart I get this error:
Code:
charged:/etc/apache2# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
[Code]....
If I do a "ps aux | grep apache" before and after I see all the root processes killed, but processes running as specified users from VritualHost directive remaining.
Now I am not an extreme linux power user, but I know a bit.

I would like to ask how can I optimize apache2 load on my dedicated server. I am hosting Facebook applications on it, but most users will get a Timed Out message when they try to access it. I was tinkering with MaxClients directive in apache2 config, and it got better, but still it's not best. Programmers are trying their best to optimize the applications at their side, but I am afraid this is an server issue.

I have a problem about redirection over Apache2 over Debian Lenny. We have build a LAMP, and our programmer make a software with these features:
When you put on your browser (i.e.) [URL], you access to the program in /var/www/vhosts/hugohome/inside. And when you put [URL] you access to the program in /var/www/vhosts/hugohome/outside. Today, if you just put [URL] our Apache answers 403 (forbidden), because we had blocked folder access. (You know....isn't the right way). Our Apache's Document Root is in /var/www/vhosts/hugohome.
Our goal is to change definitely [URL] to access -> /var/www/vhosts/hugohome/inside. This is our main intention. Also, we can continue with [URL] pointing to /var/www/vhosts/hugohome/outside. I thought, hmm easy!: I can change the DocumentRoot to /var/www/vhosts/hugohome/inside and try with an Alias to outside. But the problem is that the programmer has taken the software reference with /var/www/vhosts/hugohome and when I tried to change the Document Root the programs didn't work fine (loops, error 404, etc).
How can I do?. I have tried with Apache with many manners, but I just have a relative success with: "RedirectMatch ^/$ [URL]". It works, but the Browser shows the ugly [URL]. Our intention is just show [URL]. Unfortunately we can't work directly with the DNS servers, and I guess that I can resolve with (i.e.) Apache and Bind together.

why apache2 won't run my shell script i made.So in detail this is what i want it to do. I have a apache2 web-server running on my mac and i found some shell commands that control itunes so i wrote a shell script that basically pause's itunes. Now i have put the shell script in the cgi executable folder. and the link for the webpage is http://10.10.0.110/cgi-bin/itunes.sh but when i goto the page in my browser it just keeps loading. I have run other scripts and they work and i don't think you need root access.
