downgrade php / installing php5.2 next to php 5.3

[brouwser]

Hi all,

I've installed a LAMP server with php 5.3 ubuntu 10.04. I need to run a webapp that has problems with 5.3, so I want to install php 5.2.x as well. I have, however, no idea how to get that done. All my searches on this forum and google led to upgrading from a previous version to the latest one. Who can help?

The only way that I can think of would be to re-compile with v5.2x... not a task for the "Absolute Beginner".

It may be easier to resolve the problems that you are seeing with 5.3. I would recommend starting a new thread in the Programming Forum or post the problems you are having with PHP in the PHP forum at the main PHP site. You will find a larger audience of "hard-core" PHP-types in these locations .

Hi IndyTim,

Thanks for your response. I don't particularly need to keep php 5.3. Would it be easier to uninstall the current LAMP and reinstall it with 5.2.8?

[indytim]

If you can get it through the repository, that would also be an "easy button".

That sounds like a "no, 'cos you won't get it through the repository"?

I created a script solution for

Reverting PHP to 5.2 in Lucid 10.04

but i may not post it there so i tell you here now

create the script

#!/bin/bash

# OK, here's how to do the Apt magic to get PHP packages from the karmic repositories:

echo "Am I root?  "
if [ "$(whoami &2>/dev/null)" != "root" ] && [ "$(id -un &2>/dev/null)" != "root" ] ; then
  echo "  NO!

Error: You must be root to run this script.
Enter
sudo su
"
  exit 1
fi
echo "  OK";


#install aptitude before, if you don`t have it:
apt-get install aptitude
# or if you prefer apt-get use:
# alias aptitude='apt-get'

# finish all apt-problems:
aptitude update
aptitude -f install
#apt-get -f install

# remove all your existing PHP packages. You can list them with dpkg -l| grep php
PHPLIST=$(for i in $(dpkg -l | grep php|awk '{ print $2 }' ); do echo $i; done)
echo these pachets will be removed: $PHPLIST 
# you need not to purge, if you have upgraded from karmic:
aptitude remove $PHPLIST
# on a fresh install, you need purge:
# aptitude remove --purge $PHPLIST


#Create a file each in /etc/apt/preferences.d like this (call it for example /etc/apt/preferences.d/php5_2);
#
#Package: php5
#Pin: release a=karmic
#Pin-Priority: 991
#
#The big problem is that wildcards don't work, so you will need one such stanza for each PHP package you want to pull from karmic:

echo ''>/etc/apt/preferences.d/php5_2
for i in $PHPLIST ; do echo "Package: $i
Pin: release a=karmic
Pin-Priority: 991
">>/etc/apt/preferences.d/php5_2; done

# duplicate your existing sources.list replacing lucid with karmic and save it in sources.list.d:
#sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

# better exactly only the needed sources, cause otherwise you can get a cachsize problem:
echo "# needed sources vor php5.2:

" > /etc/apt/sources.list.d/karmic.list

aptitude update

apache2ctl restart

echo install new from karmic:
aptitude -t karmic install $PHPLIST

# at the end retry the modul libapache2-mod-php5 in case it didn't work the first time:
aptitude -t karmic install libapache2-mod-php5

apache2ctl restart

make it executeable:

chmod +x /usr/local/sbin/php5.2-downgrade

edit:
i added the historical karmic sources:

http://old-releases.ubuntu.com/ubuntu/

Thank you very much fors this script.
It saved my day.

[rubo77]

the problem now is, that the update manager wants to upgrade php to 5.3 now everytime

to tell the update-manager not to do so, you have to set the php packages to hold with

for i in $(dpkg -l | grep php|awk '{ print $2 }' ); 
do echo "echo $i hold |sudo dpkg --set-selections"; echo $i hold |sudo dpkg --set-selections; done

or so?

Thank a lot for the script...
One warning though... aptitude wanted to remove some 338M of packages from my computer... if I use apt-get instead it does not remove anything but the pap packs...
Take care

please lets not discuss
google.com/search?q="aptitude+vs+apt-get"
here
(sure: you can use apt-get if you prefer that)

one notion:

the file

/etc/apt/preferences.d/php5.2

must be called

/etc/apt/preferences.d/php5_2

without dots !!!
