[Ubuntu] ubuntu13.04 从php5.4降级到php5.3

时间：2023-11-30 20:14:02

ubuntu12.10以后，默认的deb安装库上面的php版本已经是5.4了，公司的项目使用5.4的时候，还是会出现很多问题，所以不得不降级安装5.3

顺便说一句，我原来的环境是nginx + php5.4 + mysql 的，现在只是把php5.4降级到php5.3，其它的不修复。

新建一个叫做down_to_php53.sh，然后复制下面代码进去

#!/bin/bash

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

fi

echo "  OK";

#install aptitude before, if you don`t have it:

apt-get update

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 precise:

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=precise

#Pin-Priority:

#

#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 precise:

echo ''>/etc/apt/preferences.d/php5_3

for i in $PHPLIST ; do echo "Package: $i

Pin: release a=precise

Pin-Priority:

">>/etc/apt/preferences.d/php5_3; done

echo "# needed sources vor php5.3:

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

aptitude update

#apache2ctl restart

echo install new from precise:

aptitude -t precise install $PHPLIST

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

#aptitude -t precise install libapache2-mod-php5

#apache2ctl restart

然后执行

chmod +x down_to_php53.sh

sudo ./down_to_php53.sh

执行完之后，重启php5-fpm和ngnix

sudo /etc/init.d/php5-fpm restart

sudo /etc/init.d/nginx restart

这时，访问 http://127.0.0.1/，会出现502错误，查看ngnix日志，有如下问题

// :: [crit] #: * connect() to unix:/var/run/php5-fpm.sock failed (: No such file or directory) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /phpinfo.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "127.0.0.1"

// :: [error] #: * rewrite or internal redirection cycle while internally redirecting to "/index.html", client: 127.0.0.1, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "127.0.0.1"

这是因为原来在nginx，我是这样配置的

location ~ \.php$ {

        fastcgi_split_path_info ^(.+\.php)(/.+)$;

#       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

#

#       # With php5-cgi alone:

#       fastcgi_pass 127.0.0.1:;

#       # With php5-fpm:

        fastcgi_pass unix:/var/run/php5-fpm.sock;

        fastcgi_index index.php;

        include fastcgi_params;

}

使用socket来连接，所以降级之后，还要修改一下新的配置文件

vim /etc/php5/fpm/pool.d/www.conf

找到

listen = 127.0.0.1:

加入

listen = /var/run/php5-fpm.sock

就可以了

Have fun with Ubuntu!
