Apache AJP reverse proxy

Posted on 13.07.201114.07.2011 by mario

With apache it is possible to have a reverse proxy with AJP instead of http. With the use of mod_proxy_ajp it is very simple to set up and faster than just plain http protocol

<VirtualHost *:80>
    ServerName jenkins
    DocumentRoot "/mario/Apache22/htdocs"
    <Directory "/mario/Apache22/htdocs">
        Options Indexes Includes FollowSymLinks
        AllowOverride All
        Order Allow,Deny
        Allow from all
        Deny from none
    </Directory>
    <Location />
        ProxyPass ajp://localhost:8009/
        ProxyPassReverse ajp://localhost:8009/
    </Location>

    SetEnv vhostname jenkins
    Header add X-Server-Name %{vhostname}e
</virtualhost>

Than start the backend server, in this case only with AJP and listen only on localhost

java -jar jenkins.war --httpPort=-1 --ajp13ListenAddress=127.0.0.1

mod lua error handling sux

Posted on 05.01.2011 by mario

I still dislike the 500 error handling in lua. Well scripting got easier with practicing :P But the error handling realy sux a lot compared to PHP where I come from. I made a bit “benchmarking”. OK I took very different scripts, but PHP seems faster to me than lua. Plus for lua is that you are able to write direcly into apache log files.

first script for mod_lua apache2.3/2.4

Posted on 30.11.201030.11.2010 by mario

function handle(r)
	r.content_type = "text/html"
	--r.headers_out["X-Powered-By"] = "mod_lua; " .. _VERSION
	r:puts("Hi!")
	return apache2.OK
end

Mod lua expects a function with the name handle() else there is a 500 Error. The error handling is pretty anoying…

compile lua on windows

Posted on 30.11.201030.11.2010 by mario

Grab the “newest” (2008) http://www.lua.org/ftp/lua-5.1.4.tar.gz
unpack it. Compiling with VC++ is very easy.

Open the x64 %comspec% /E:ON /V:ON /T:0E /K “C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.cmd” /Release
or x86 command line
%comspec% /k “”C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat”” x86

browse to lua folder and run

etc\luavs
copy /y src\*.* .\

Done!

This is my first trial giving a third party module a signature.

reverse proxy for utorrent part 2

Posted on 21.11.201008.01.2019 by mario

In my last post about utorrent (µtorrent) I was frustrated that I wasn’t able to change the url from /gui/ to /tor/
Woot! In apache 2.3 which will be apache 2.4 and I think it will be released in early 2011 the proxy module is much better and there it works to have a different URL :-) Even as ALPHA or BETA version the new apache rocks a lot and runs stable. In condition with mod_fcgid it is real cool technology e.g. running PHP separated form apache that allows to run different PHP version of the server in vhosts or directories. Also running a non thread safe PHP version. Speed! IPv6 would be fine, but the offered patches are not applied to trunk :-/There is an annoying bug in mod_fcgid. I’m glad I found a fix for it (help from Tom Donovan and Sob).

Disable AllowOverride (htaccess to httpd.conf)

Posted on 15.11.201008.01.2019 by mario

AllowOverride is one of the things that slow down a lot. Disabling it makes apache faster. It is a horror to migrate all .htaccess files by hand. BUT here is a PHP script from Paul Reinheimer which makes it realy easy :-)

Get it htaccess.php

tune your server!
