--最近准备开发部署RoR,转一篇文章备用
可以毫不夸张地说,服务器应用的部署是整个开发周期中难度最大的任务之一。且不说要如何使得应用可扩展性好、系统吞吐量大、稳定性好...单只让应用run起来,就不是一件很简单的事情。Rails作为一个Web应用框架,几乎是最大程度地减轻了开发人员的负担:安装Ruby运行环境、Rails和所需使用的数据库服务器之后,开发人员就可以开始用Rails自带的WEBrick服务器进行开发和调试了,基本上不需要对环境作太多的配置(当然,如果需要使用一些Ruby或者Rails的第三方库,自然是需要额外安装等)。然而到了将应用部署到实际环境中的时候,我们就要接触到繁杂的部署过程了,这时候,只靠官方的文档,往往是不够的,一般还要加上Google和最重要的,耐心。
好,在部署之前,我们看看Rails应用可以在什么环境下部署:
通常来说,比较一下上面的表格,我们会很自然地选择lighttpd-fcgi这种方案来部署我们的应用,soopie正是选用了这一方案。
接下来我们给出Rails应用在Linux服务器上部署的基本过程:

通常来说,比较一下上面的表格,我们会很自然地选择lighttpd-fcgi这种方案来部署我们的应用,soopie正是选用了这一方案。
接下来我们给出Rails应用在Linux服务器上部署的基本过程:
- 所需要的软件包:
-
- lighttpd-1.4.10.tar.gz
- fcgi-2.4.0.tar.gz
- ruby-1.8.4.tar.gz
- rubygems-0.8.11.tgz
- ruby-fcgi-0.8.6.tgz
- 安装步骤:
- 安装Ruby
- 安装rubygems
- 安装ruby-fcgi
- 安装rails,用命令行命令 gem install rails
- 安装lighttpd(创建用户www和组www, 创建目录/var/lighty作为文档根目录, /var/lighty/logs作为日志目录)
- 最关键的步骤:在lighttpd的配置文件(默认是/etc/lighttpd/lighttpd.conf)中配置rails应用支持。这里给出一个配置文件的完整例子(用Virtual host 方式配置,容易支持一个主机上多个rails应用):更详细的信息可以参考这里。
# lighttpd configuration file
#
# use it as a base for lighttpd 1.0.0 and above
#
# $Id: lighttpd.conf,v 1.7 2004/11/03 22:26:05 weigon Exp $
