Ubuntu 10.04下的php5.3降级到php5.2
因为Ubuntu 10.04下Zend Optimizer 3.3.9都还没有开始支持php5.3，所以把ubuntu10.4的php5.3降级到php5.2
步骤:
１ 增加karmic源
x@y:~$sudo vi /etc/apt/sources.list.d/karmic.list
deb http://archive.ubuntu.com/ubuntu/ karmic main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ karmic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ karmic-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ karmic-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu karmic-security main restricted universe multiverse
deb-src http://security.ubuntu.com/ubuntu karmic-security main restricted universe multiverse

3 建立降级脚本
x@y:~$vi down5.3-5.2.sh
#! /bin/sh -e
# script to install PHP 5.2 from 9.10 on 10.04
# And pin it so it does not get updated
# package available and may be installed later
PKGSAVAILABLE="`aptitude search -F '%p' php5` php-pear"
PKGSINSTALLED=`dpkg -l | grep php | awk '{print $2}'`
aptitude remove $PKGSINSTALLED
# disable duplicate entries
grep 'ubuntu.com' /etc/apt/sources.list | sed s/lucid/karmic/g > tee /etc/apt/sources.list.d/karmic.list
for PACKAGE in $PKGSAVAILABLE
do
# aptitude seems to use /etc/apt/preferences but not /etc/apt/preferences.d/*
# cf https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/508545
if egrep -q "Package: ?$$" /etc/apt/preferences
then
echo "$PACKAGE already in preference"
else
echo "\nPackage: $\nPin: release a=karmic\nPin-Priority: 991" >> /etc/apt/preferences
fi
done
aptitude update
aptitude install $PKGSINSTALLED
njava@njava.com:~$chmod 755 down5.3-5.2.sh
