安装Nginx和Passenger

# APT安装 nginx+passenger
# 参考 https://www.phusionpassenger.com/library/install/nginx/install/oss/trusty/
# Install our PGP key and add HTTPS support for APT
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
sudo apt-get install -y apt-transport-https ca-certificates

# Add our APT repository
sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update

# Install Passenger + Nginx
sudo apt-get install -y nginx-extras passenger

安装依赖工具

# 安装nodejs，后面会有依赖
sudo apt-get install nodejs
# 安装Git
sudo apt-get install git

配置 Nginx

sudo vi /etc/nginx/nginx.conf
# 去掉下面两行的注释
# passenger_root /some-filename/locations.ini;
# passenger_ruby /usr/bin/passenger_free_ruby;

# 修改Nginx配置
sudo rm /etc/nginx/sites-enabled/default
sudo vi /etc/nginx/sites-enabled/example.com.conf

server {
    listen 80 default;
    server_name ror.cbd; # 如果是本地VM调试修改hosts文件
    root /home/deploy/code_from_git/toy_app/public;

    passenger_enabled on;
}

部署代码

# clone 代码

# bundle安装gems
gem install bundle 
# 如果失败了就切回ruby-china的源
gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/
gem sources -l

# 进入项目目录
bundle install
# 查看服务器的secret值
rake secret

# 在config/secrets.yml，替换掉production设置中的 <%= ENV["SECRET_KEY_BASE"] %>
# 或者在环境变量里添加；
# 或者在production的组里添加 dotenv-rails 这个gem，之后在项目根目录下新建 .env 文件，添加配置
SECRET_KEY_BASE=b78a0f839f2be596a1543f13bb90b965d5736dcb190504b10c3de05eb2fcb66d1ab6d92b3450e603e5768bba1830604a506bcb5a0f6040ec110b2f55e2a2a78e
