[TYPO3-debian] typo3 installation on apache2, PHP4 parallel to PHP5

[Alexander Schories]

Hello Ute,

> I have an apache2 server with PHP5 module (PHP5.1.2-1 as

No, Typo3 3.8.1 and 4.0.0 both work *excellent* with PHP5! 99% of the
extensions do also work with PHP5, many of them now even DEPEND on PHP>=5.0!

Please be aware that - although some users here mentioned to successfully
run eA with php-cgi - eA still runs best with php as an apache module (in
your case: libapache2-mod-php5).

In your webserver`s config files, which are located in /etc/apache2.
However, if you can, try to use PHP5 only. Avoid those .php4 and .php5
suffixing, because renaming, symlinking or even patching many php files only
causes unnecessary headaches, esp. every time you like to "click and update"
Typo3 or similar php-based software.. :)

Please use the source packages directly from typo3.org:

http://sourceforge.net/project/showfiles.php?group_id=20391&package_id=14557
&release_id=52628

They will work pretty well! No need for installers or .deb-Packages. These
are not 100% ready and up2date afaik.

If you are in doubt, which debian package to install to benefit from all
typo3 features, please just read the last lines of this answer.

Yes, please explain how much "access" do you have on your vhost-machine -
because compiling & installing eA on a vhost possibly might fail due to
restrictions..

And please keep in mind to configure php and eA, means give both enough (in
case of eA: shm-) memory to play with.


Feel free to ask further questions regarding, esp. those Typo3 & Debian
related ones, on this list:

Michael Stucki, i and many other will help you there in case it is more a
Typo3-related question.
