ubuntu 10.04 php5.3 to php5.2

要把ubuntu 系统里的php 从 5.3 或更高版本降到低版本 5.2 。搜了很多资料，千篇一律都有问题，估计都没试过，ubuntu 的karmic 源地址基本上都失效了。这里提供一个修改后的脚本。

#!/bin/bash

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:

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，本人使用nginx和fastcgi模式

apt-get install php5-cli php5-cgi php5-mysql

pkill -9 php-cgi

spawn-fcgi -a 127.0.0.1 -p 9000 -C 10 -u jimmy -f /usr/bin/php-cgi

service nginx restart

执行下面代码，告诉update-manager 不要再提醒更新php到高版本。

#!/bin/bash

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

如果希望更新到php高版本，则

#!/bin/bash

for i in $(dpkg -l | grep php|awk '{ print $2 }' );

do echo "echo $i install |sudo dpkg --set-selections"; echo $i install |sudo dpkg --set-selections; done
