PHP5 FastCGI init.d scriipt for Debian/Ubuntu

Recently, I am using Nginx + PHP5 FastCGI as the new web platform. I really need a init.d script for PHP5 FastCGI. It is not so difficult according to the skeleton.

First of all, make sure to install php5-cgi and spawn-fcgi.

sudo apt-get install php5-cgi spawn-fcgi

Second, create the /etc/init.d/php-fastcgi script, as below:

#! /bin/sh
### BEGIN INIT INFO
# Provides:          php-fastcgi
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: PHP5 FastCGI mode
# Description:       This file should be used to construct scripts to be
#                    placed in /etc/init.d.
### END INIT INFO

Add php-fastcgi into the start list

sudo update-rc.d php-fastcgi default

this will start for init level 2,3,4,5

Firefox 免插件发新浪 weibo 大法

Firefox 具有 Smart Keywords这个功能。她让我们可以定义一个关键字并用这个关键字来标示一个特定的网址。利用这个功能，我们实际上可以做很多有趣的事情，比如发Sina围脖。具体步骤如下：

使用 Firefox
打开 baidu.com 在搜索框上点右键
点 "Add Keyword for this Search..."
这时会弹出一个对话框, 在 "Name" 项输入 "sina weibo" 其实输入什么都可以， “keyword" 可以选 wb
然后保存
用 bookmark manager 打开这个新建的 Smart Keyword，打开 properties 属性对话框。然后在 “Location” 里面输入下面的代码：

javascript:(function(){f='http://v.t.sina.com.cn/share/share.php?url='+encodeURIComponent(window.location.href)+'&title=%s';a=function(){if(!window.open(f,'location=yes,links=no,scrollbars=no,toolbar=no,width=550,height=550'))location.href=f};if(/Firefox/.test(navigator.userAgent)){setTimeout(a,0)}else{a()}})()

这就全部搞定了！今后在任何一个网页，你只要切换到Address Bar。可以用Ctrl+D/Ctrl+L 快速切换。然后输入： wb 任何你想输入的文字。回车，这就会打开一个新的窗口/tab 提示你围脖的内容。Over！
