1. 以非root用户更新系统
sudo apt-get update sudo apt-get upgrade 2. 设置主机名，如果是系统是图形安装的，则这步骤可以忽略 sudo hostname your-hostname
Add 127.0.0.1 your-hostname：
sudo vim /etc/hosts
Write your-hostname in：
sudo vim /etc/hostname
Verify that hostname is set：
hostname
3. 以非root安装 git &curl
新的ubuntu系统，需要安装这些包；
sudo apt-get install curl git
4. 安装RVM
$ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )add below to your .bashrc. # This loads RVM into a shell session.
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"Once you edit your bashrc file execute the following to load rvm without logging out and back in
把~/.bashrc中的return都删除，[ -z "$PS1" ] && return 改成 [ -z "$PS1" ]
运行：
source ~/.rvm/scripts/rvmJust to be safe check wether rvm is a function, which is what it should be.
type rvm | head -n1 5. Install ruby 1.9.2 sudo aptitude install build-essential bison openssl libreadline5 libreadline5-dev curl git-core zlib1g zlib1g-dev libssl-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libmysqlclient-dev rvm install 1.9.2 rvm use 1.9.2 --default 6. 安装 rails3 gem install rails 7. 安装 passenger and nginx gem install passenger rvmsudo passenger-install-nginx-module 这个步骤需要一些required softwares，可以按照提示完成 8 测试nginx 8.1 检查nginx的安装结果： sudo vi /opt/nginx/conf/nginx.conf 确保以下为ruby 1.9.2（以rvm use 1.9.2 --default保持一致） 和 passenger 3 http { passenger_root /home/leslin123/.rvm/gems/ruby-1.9.2-p180/gems/passenger-3.0.3; passenger_ruby /home/leslin123/.rvm/wrappers/ruby-1.9.2-p180/ruby; 8.2 启动 sudo /opt/nginx/sbin/nginx 打开 nginx的欢迎界面：http://localhost/ 如果看到：Welcome to nginx! ， 那么恭喜你！ 9. Install latest version MySQL sudo apt-get install mysql-server mysql-client 这个步骤花费的时间比较多，since需要下载的软件多于20M 根据提示为root设置相应的密码，3344*** 10. 创建rails application 在当前用户目录中，如/home/les***/rorails 创建 rails new helloubuntu 进入应用目录，运行 bundle install 这时sqllite3会被安装 11. 运行 rails server 启动的log为： leslin123@ubuntuServerofLeslin:~/rorails/helloubuntu$ rails server => Booting WEBrick => Rails 3.0.4 application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2011-02-26 11:28:38] INFO WEBrick 1.3.1 [2011-02-26 11:28:38] INFO ruby 1.9.2 (2011-02-18) [x86_64-linux] [2011-02-26 11:28:38] INFO WEBrick::HTTPServer#start: pid=14429 port=3000 打开目录http://localhost:3000/, 可以看到rails欢迎界面，但这个只是说明rails 配置成功。 显然，所希望的web服务器和数据库都没有配置好！ 12. 配置MySQL rails new helloMySQL -d mysql cd ./helloMySQL 问题： rails server Could not find gem 'mysql2 (>= 0, runtime)' in any of the gem sources listed in your Gemfile. 解决方法： bundle update Installing mysql2 (0.2.6) with native extensions 进入应用程序目录，将root的密码添加到database.yml 中，否则启动后会出现类型下面的，数据库连接错误； Access denied for user 'root'@'localhost' (using password: NO) rake db:create rails server 打开欢迎界面http://0.0.0.0:3000/； 点击： About your application’s environment 查看相关信息，包括： Database adaptermysql2 好了，现在就剩下最后一项了。 13. 配置nignx服务器 认真者可以在安装Nignx看到如下提示： ---------------------------------------**************************************************-------------------------------------- -------------------------------------------- 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 /home/leslin123/.rvm/gems/ruby-1.9.2-p180/gems/passenger-3.0.3; passenger_ruby /home/leslin123/.rvm/wrappers/ruby-1.9.2-p180/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; } And that's it!
