CentOS5.2 + Apache + lighttpd下搭建Ruby on Rails开发环境

最近看上了Ruby on Rails的敏捷开发技术了，虽然早已不是什么新鲜玩意了，

不过看着它越来越流行了，还是想看一看里面的究竟啊， 先从搭建Ruby on Rails的环境入手吧。

1.安装Ruby

rails框架也是Ruby做的，自然要先安装Ruby了，
yum install ruby -y

确认一下
Ruby -v

2.安装RubyGems

RubyGems是Ruby函数库的管理系统

在此之前先要导入dlutter软件仓库

[root@host1 ~]# vi /etc/yum.repos.d/dlutter.repo

修改成

[dlutter]
name=Unsupported RHEL5 packages (lutter)
baseurl=http://people.redhat.com/dlutter/yum/rhel/5/$basearch/
enabled=0
gpgcheck=0

确认
[root@host1 ~]# yum --enablerepo=dlutter list

然后直接用命令安装RubyGems

[root@host1 ~]# yum --enablerepo=dlutter -y install rubygems.noarch
确认版本
[root@host1 ~]# gem --version
1.2.0

安装好应该是1.2.0的版本，最新是1.3.0的，有兴趣的朋友可以用源码编译升级


3.rails框架的导入

这个比较简单，直接用RubyGems来安装

[root@host1 ~]# gem install rails

4.最关键也是比较复杂的一步是Apache+lighttpd两个Web服务器的导入

关于Web服务器的选择，通常有很多争议，就Ruby on Rails而言，很多都是采用lighttpd
当作Web Server，当作FastCGI应用程序来跑，但是lighttpd还是很难代替Apache的地位，
特别是Rails程序以外还有其他Web程序的时候、不大可能完全移植到lighttpd上的，所以在这里，只是Rails程序跑在lighttpd上，对Rails程序的请求通过Apache转送过来。

先安装FastCGI

[root@host1 ~]# wget http://www.fastcgi.com/dist/fcgi-2.4.0.tar.gz
[root@host1 ~]# tar zxvf fcgi-2.4.0.tar.gz
    :
[root@host1 ~]# cd fcgi-2.4.0
[root@host1 fcgi-2.4.0]# ./configure
    :插入代码
[root@host1 ~]# gem install fcgi
[root@host1 fcgi-2.4.0]# make
    :
[root@host1 fcgi-2.4.0]# make install
    :

[root@host1 fcgi-2.4.0]# cd
[root@host1 ~]# rm -rf fcgi-2.4.0*

下面用RubyGems把Ruby的FastCGI的包导进来
接下去就要安装lighttpd服务器了，先导入RPMforge 软件仓库

[root@host1 ~]# wget http://dag.wieers.com/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
[root@host1 ~]# rpm -Uhv rpmforge-release-0.3.6-1.el5.rf.i386.rpm
[root@host1 ~]# vi /etc/yum.repos.d/rpmforge.repo
enabled = 1
    ↓
enabled = 0
[root@host1 ~]# wget http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt
[root@host1 ~]# rpm --import RPM-GPG-KEY.dag.txt

确认
[root@host1 ~]# yum --enablerepo=rpmforge list

开始安装
[root@host1 ~]# yum --enable=rpmforge install lighttpd
    :
[root@host1 ~]# yum --enable=rpmforge install lighttpd-fastcgi
    :

一般系统已经有Apache服务了，为了避免冲突，还要配置一下lighttpd，

[root@host1 ~]# vi /etc/lighttpd/lighttpd.conf


#                               "mod_rewrite",
#                               "mod_redirect",
#                               "mod_alias",
    ↓
                               "mod_rewrite",
                               "mod_redirect",
                               "mod_alias",

#                               "mod_fastcgi",
    ↓
                               "mod_fastcgi",

#server.port                = 81
    ↓
server.port                = 3000  ←端口设置成3000不要与apache的重复

#server.bind                = "127.0.0.1"
    ↓
server.bind                = "localhost" 

自启动
[root@host1 ~]# chkconfig lighttpd on

Rails应用程序的基本设置



[root@host1 ~]# cd /srv/www/lighttpd
[root@lighttpd]# mkdir rails
[root@lighttpd]# rails ./rails

赋予lighttpd用户的权限
[root@host1 ~]# cd
[root@host1 ~]# chown -R lighttpd. /srv/www/lighttpd/rails
[root@host1 ~]# chmod +x /srv/www/lighttpd/rails/public/dispatch.*

Apache+lighttpd的设定



[root@host1 ~]# vi /etc/lighttpd/lighttpd.conf

加在末尾

$HTTP["host"] =~ "ithurricane.dip.jp" {
    server.document-root = "/srv/www/lighttpd/rails/public"
    alias.url = ( "/" => "/srv/www/lighttpd/rails/public/" )
    server.indexfiles = ( "index.html", "dispatch.fcgi" )
    accesslog.filename = "/var/log/lighttpd/access.log"
    server.errorlog = "/var/log/lighttpd/server.log"
    server.error-handler-404 = "/dispatch.fcgi"
    url.rewrite = ( "^/$" => "index.html", "^([^.]+)$" => "$1.html" )

    fastcgi.server = (
        ".fcgi" => (
            "localhost" => (
                "socket" => "/tmp/rails.fcgi.socket",
                "bin-path" => "/srv/www/lighttpd/rails/public/dispatch.fcgi",
                "bin-environment" => (
                    "RAILS_ENV" => "production",
                    "RAILS_ROOT" => "/srv/www/lighttpd/rails"
                    ),
                "idol-timeout" => 10,
                "check-local" => "disable",
                "min-procs" => 1,
                "max_procs" => 20
            )
        )
    )
}
[root@host1 ~]# /etc/init.d/lighttpd start

下面还要设置一下Apache把对Rails的请求转发到lighttpd

[root@host1 ~]# vi /etc/httpd/conf.d/virtualhost.conf
<VirtualHost *:80>
    ServerName ithurricane.dip.jp
    <IfModule mod_proxy.c>
        ProxyRequests Off
        ProxyPreserveHost On
        ProxyPass / http://localhost:3000/
        ProxyPassReverse / http://127.0.0.1:3000/
    </IfModule>
</VirtualHost>

大功告成，重载一下设定即可



[root@host1 ~]# /etc/init.d/httpd reload

最后导入图像处理库，和数据库SQLite3，这些都比较简单，一笔带过了，

[root@host1 ~]# yum install freetype
    :
[root@host1 ~]# yum install libpng
    :
[root@host1 ~]# yum install gd-devel
    :
[root@host1 ~]# gem install ruby-gd -- --build-flag --with-freetype
    :
[root@host1 ~]# gem install sqlite3-ruby
Select which gem to install for your platform (i686-linux)
 1. sqlite3-ruby 1.2.1 (ruby)
 2. sqlite3-ruby 1.2.1 (mswin32)
 3. sqlite3-ruby 1.2.0 (mswin32)
 4. sqlite3-ruby 1.2.0 (ruby)
 5. Skip this gem
 6. Cancel installation
> 1

终于完成了，把rails的服务打开来，看看成果吧，注意跑的是Apache的80端口哦

[root@host1 ~]#  cd /srv/www/lighttpd/rails
[root@rails ~]#  ruby script/server
