Recompiling PHP / Apache for a complete noob?

Hi there,
I'm running ISPConfig 2 on Debian Lenny (vServer). I am using a very large IP.Board & Gallery. The devs suggested that I should remove suhosin and in order to do that, I would have to recompile PHP / Apache without suhosin.

Can someone explain to me how that is done? I've never done that before...

 

Ok, I've found documentation on compiling Apache:
http://httpd.apache.org/docs/2.2/install.html

But, the question is: can I do that with ISPConfig 2 installed? Or is that gonna break something?

 

Just remove php5-suhosin...

Code:

aptitude remove php5-suhosin

... and restart Apache.

 

Is it really that simple? Because I've done that and the Invisionpower tech told me I'd have to recompile Apache/PHP to do it "properly". Is he talking out his a$$?

 

Do you have a phpinfo(); file? Does it still show Suhosin anywhere on the page?

 

Yeah it does:

 

Here's the phpinfo():

In this case you must rebuild PHP. This tutorial (although it's quite old now) should give you the idea: http://www.howtoforge.com/linux_apache2_ssl_php5_zendoptimizer_ioncubeloader

 

Thanks Falko

 

Ok, I downloaded PHP 5 (source code), unpacked it and ran this command:

Code:

./configure --with-apxs2=/usr/sbin/apxs --with-mysql=/var/lib/mysql --enable-track-vars --enable-sockets --with-config-file-path=/etc --enable-ftp --with-zlib --with-openssl=/usr/local/ssl --enable-force-cgi-redirect --enable-exif --with-gd --enable-memory-limit --disable-debug --disable-rpath --disable-static --with-pic --with-layout=GNU --enable-calendar --enable-sysvsem --enable-sysvshm --enable-sysvmsg --enable-trans-sid --enable-bcmath --with-bz2 --enable-ctype --with-db4 --with-iconv --enable-filepro --with-gettext --enable-mbstring --enable-shmop --enable-wddx --disable-xml --with-xmlrpc --enable-yp --with-zlib --without-pgsql --enable-dbx --enable-experimental-zts --without-mm --enable-gd-native-ttf --with-imap-ssl --enable-soap --enable-dbase --disable-suhosin

But the server tells me:

Code:

Configuring SAPI modules
checking for AOLserver support... no
checking for Apache 1.x module support via DSO through APXS... no
checking for Apache 1.x module support... no
checking whether to enable Apache charset compatibility option... no
checking for Apache 2.0 filter-module support via DSO through APXS... no
checking for Apache 2.0 handler-module support via DSO through APXS... 

Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)

The output of /usr/sbin/apxs follows:
./configure: line 6461: /usr/sbin/apxs: No such file or directory
configure: error: Aborting

I've never done this before and I don't have a real clear picture of what apxs is.
The OS is Debian Lenny with ISPConfig (installed as per the Perfect Setup Howto).

 

Install apache2-prefork-dev:

Code:

aptitude install apache2-prefork-dev

Then use /usr/bin/apxs2 instead of /usr/sbin/apxs.
