Linux 环境passenger多ruby版本共存部署

1.安装rvm

mkdir -p ~/.rvm/src/ && cd ~/.rvm/src && rm -rf ./rvm/
git clone git://github.com/wayneeseguin/rvm.git
cd rvm && ./install

 2.修改用户配置文件.bashrc,添加一行代码:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

 3.重启Terminal.

查询当前版本: rvm info

列出版本: rvm list

更多命令,访问 http://rvm.beginrescueend.com/rvm/

 

4.安装 ruby

4.1.安装REE

rvm install ree

4.2.安装 ruby- 1.9 . 2

rvm install ruby-1.9.2-p180

小技巧：用工具下载好ruby-enterprise-1.8.7-2011.03.tar.gz,ruby-1.9.2-p180.tar.bz2,yaml-0.1.3.tar.gz，然后手工放到~/.rvm/archives 目录下，再运行安装 命令，可以直接解压安装。

 

5.将某一个版本的ruby设为默认

$ rvm --default use 1.9.2   #设置1.9.2为默认版本

$ rvm default      #通过default可以快速回到默认版本
$ rvm list default     #查看当前版本设置信息
$ rvm reset     #恢复系统默认设置

 

 

6.安装rails

6.1.安装rails2

$ rvm ree-1.8.7-2011.03
$ rvm gemset create rails2
$ rvm genset use rails2
$ gem install --no-ri --no-rdoc rails -v=2.3.12

 6.2.安装rails3

$ rvm ruby-1.9.2-p180
$ rvm gemset create 'rails3'
$ rvm gemset use rails3
$ gem install rails
Successfully installed activesupport-3.0.9
Successfully installed builder-2.1.2

Successfully installed rdoc-3.6.1
Successfully installed railties-3.0.9
Successfully installed bundler-1.0.15
Successfully installed rails-3.0.9
24 gems installed

 

7.创建别名

$ rvm alias create ree ree-1.8.7-2011.03 #为ree-187的Ruby版本创建一个别名叫：ree
$ rvm alias create ruby192 ruby-1.9.2-p180
$ rvm use ree #通过别名迅速切换
$ rvm delete ree #删除别名
$ rvm alias list # 查看所有的别名

 

9.使用gemset

$ rvm use ree@rails2
$ rvm use ruby192@rails3 --default   #设置默认

 

10.安装passenger

$ gem install passenger
$ rvm wrapper 1.9.2 passenger
$ passenger-install-nginx-module
# Passenger will help you install nginx, the folder is in /opt/nginx
Downloading Nginx...
# wget -O /tmp/root-passenger-12180/nginx.tar.gz http://sysoev.ru/nginx/nginx-1.0.0.tar.gz
--------------------------------------------

Nginx with Passenger support was successfully installed.

The Nginx configuration file (/opt/nginx/conf/nginx.conf)
must contain the correct configuration options in order for Phusion Passenger
to function correctly.

This installer has already modified the configuration file for you! The
following configuration snippet was inserted:

  http {
      ...
      passenger_root /usr/local/rvm/gems/ruby-1.9.2-p180@rails3/gems/passenger-3.0.7;
      passenger_ruby /usr/local/rvm/wrappers/ruby-1.9.2-p180@rails3/ruby;
      ...
  }

After you start Nginx, you are ready to deploy any number of Ruby on Rails
applications on Nginx.

Press ENTER to continue.

--------------------------------------------

Deploying a Ruby on Rails application: an example

Suppose you have a Ruby on Rails application in /somewhere. Add a server block
to your Nginx configuration file, set its root to /somewhere/public, and set
'passenger_enabled on', like this:

   server {
      listen 80;
      server_name www.yourhost.com;
      root /somewhere/public;   # <--- be sure to point to 'public'!
      passenger_enabled on;
   }

 

11.设置IP和App

11.1.单个网卡eth1配置多个ip地址

ifconfig eth1:0 192.168.56.101 netmask 255.255.255.0 up
ifconfig eth1:1 192.168.56.102 netmask 255.255.255.0 up

 

11.1.设置demo2(ree@rails2)
cd /opt/rails_apps/
rails demo2
cd demo2

11.2.设置demo3(ruby192@rails3)
cd /opt/rails_apps/
rails new demo3
cd rails3
passenger start -a 127.0.0.1 -p 3001 -d

(此命令执行俩次，详细信息见passenger.zip)

12.配置nginx

http{
    ...
    passenger_root /usr/local/rvm/gems/ruby-1.9.2-p180@rails3/gems/passenger-3.0.7;
    passenger_ruby /usr/local/rvm/wrappers/ruby-1.9.2-p180@rails3/ruby;

    server {
        listen 80;
        server_name 192.168.56.101;
        root /opt/rails_apps/demo2/public;
        passenger_enabled on;
        rails_env development;
    }

    server {
        listen 80;
        server_name 192.168.56.102;
        root /opt/rails_apps/demo3/public;
        location / {
          proxy_pass http://127.0.0.1:3001;
          proxy_set_header Host $host;
        }
    }
}

 

启动：/opt/nginx/sbin/nginx

停止：/opt/nginx/sbin/nginx -s stop

访问：

rails2:http://192.168.56.101/

rails3:http://192.168.56.102/

 

13.直接通过项目名称访问,在/etc/hosts中添加:

192.168.56.101 demo2
192.168.56.102 demo3
