登陆云端之后，发现报错如下：
ssh [email protected]

Are you sure you want to continue connecting (yes/no)? yes

C
C.UTF-8

en_AG.utf8

1.然后切换到 yz00 这个用户
su yz00 cd
2. 安装依赖以及ruby语言
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential \
libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 \
libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.1.5
rbenv global 2.1.5检查ruby版本
ruby -v3.安装mysql数据库
sudo apt-get install mysql-server mysql-client libmysqlclient-dev
数据库root密码：123
4.安装 nginx 和 passenger
nginx 是一个高速的 web 服务器， passenger 是跑 rails 应用需要的“应用服务器”，总之它们都是服务器。
安装需要的密钥：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7 vi /etc/apt/sources.list
此时报错
E45: 'readonly' option is set (add ! to override)
这些错误往往是我们使用ssh时出现的
vim filename改为vi filename即可,修改完之后
：wq! 即可退出
安装 nginx 和 passenger，注意这样安装，就不用执行
passenger-install-nginx-module
了，以前的运行这个命令的时候经常 会出现由于内存不够导致执行失败，很烦人的。
sudo apt-get install nginx-extras passenger
这时候报错Operation too slow.
关闭命令行之后，重启连接yz00即可。
此时访问对应的域名（http://XXXX.com/）就ok了。
6.安装 javascript 的运行环境，这个是跑 rails 应用必须的。sudo apt-get install nodejs
7.把代码移过去
scp -r yz00@XXXX（对应域名）:
输入密码即可
8. 安装 bundler，并用它来把项目需要的依赖包都安装好gem install bundler rbenv rehash cd meetup/ bundle
报错又来了....JS环境出了问题
Important: You may need to add a javascript runtime to your Gemfile in order for bootstrap's LESS files to compile to CSS.
**********************************************
ExecJS supports these runtimes:
therubyracer - Google V8 embedded within Ruby
therubyrhino - Mozilla Rhino embedded within JRuby
Node.js
Apple JavaScriptCore - Included with Mac OS X
Microsoft Windows Script Host (JScript)
**********************************************
gem install execjs gem 'therubyracer'
9.填写需要的配置
cd config vim database.yml # 填写数据库的密码
default: &default adapter: mysql2
encoding: utf8
pool: 5 username: root
password: development:
<<: *default
database: db/development.sqlite3 test:
<<: *default database:
db/test.sqlite3 production:
<<: *default
database: shuqian_production
username: root
password: 123(install时设置为123)
10.创建数据库
bundle exec rake db:create db:migrate RAILS_ENV=production
11.把 js/css 等 asset 文件做预处理
bundle exec rake assets:precompile RAILS_ENV=production # precompile 这一句如果不加 RAILS_ENV 设置还是会有问题的，font-awesome 字体文件加载不了
这样的结果是在，public/ 之下出现了很多代哈希值的文件名，粗略的可以认为这样的措施就是为了提高网站访问速度。
12.修改 nginx 和 passenger 配置
打开 nginx 的配置文件：
sudo vim /etc/nginx/nginx.conf
/passen,查找下面两行
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini; passenger_ruby /usr/bin/ruby;
将第二行改为,可以用ctrl+X+F自动补齐代码
passenger_ruby /home/yz00/.rbenv/shims/ruby;
然后要来为 signup 项目，专门创建一个服务器配置文件。
cd /etc/nginx/sites-enabled rm default sudo vim meetup.conf
shuqian.conf 中的内容如下
server {
listen 80 default;
server_name http://hhcd.cn/;
passenger_enabled on;
gzip on;
root /home/yz00/shuqian/public;
}
nginx 的配置修改后，不要忘了重启 nginx 服务器
sudo service nginx restart
touch tmp/restart.txt
上述命令重新加载设置
