nginx 和 mysql 環(huán)境需要事先搭好

1. 服務器上創(chuàng)建用戶，修改登錄shell為 bash chsh deploy -s /bin/bash

2. 添加操作機的 ssh key 到服務器上實現(xiàn)免密碼連接

3. 安裝 rbenv (請查看官方文檔)

   git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
   echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
   echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
   exec $SHELL
   git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
   rbenv install 2.2.3

因為 cdn 被墻，所以需要修改下載地址

find . | grep 2.2.3
vi ./.rbenv/plugins/ruby-build/share/ruby-build/2.2.3

可以順便禁掉 rdoc

echo "gem: --no-ri --no-rdoc" > ~/.gemrc

ruby-build 依賴

apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev

還要安裝 bundler

gem install bundler

4. 如果部署在非用戶目錄，創(chuàng)建目錄并設置權限（如 /var/www/）
   執(zhí)行 mina init 并修改配置文件

5. mina setup，然后編輯生產環(huán)境的配置文件 (如 database.yml, secrt.yml, puma.rb 等）
   執(zhí)行 rake secret 生成密鑰

6. 添加服務器的 ssh key 到 git 倉庫獲取訪問權限

7. 數(shù)據(jù)庫手動創(chuàng)建

   CREATE DATABASE rails_app DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

修改字符集

ALTER DATABASE report
   CHARACTER SET utf8
   COLLATE utf8_general_ci

8. 配置 nginx 和 puma

9. mina deploy

Puma

# Gemfile
gem 'mina-puma', require: false

# deploy.rb
require 'mina/puma'

必須 puma.rb 中添加下面的配置才能夠通過 mina 來重啟 puma

state_path "#{application_path}/shared/tmp/sockets/puma.state"
activate_control_app "unix://#{application_path}/shared/tmp/sockets/pumactl.sock"

自定義任務

通過依賴 environment 加載 ruby 和 bundle

desc "rake db:seed"
task :seed => :environment do
    queue "cd #{deploy_to}/#{current_path}"
    queue "bundle exec rake db:seed RAILS_ENV=production"
end
