capistrano 自动部署配置
1. 新建Rails项目
2. 修改 Gemfile
group :development do
gem 'capistrano'
gem 'rvm-capistrano'
gem 'capistrano-recipes', github: 'fiberead/capistrano-recipes'
end
3. 保证项目配置正确
bundle
capify .
4. 修改deploy.rb
# 使用RVM部署
require "rvm/capistrano" # Load RVM's capistrano plugin.
require 'bundler/capistrano'
# bundler配置
set :bundle_flags, "--deployment " # --quiet
set :bundle_without, [:development, :test]
# 需要更新配置
###############
set :server_ip, '192.168.0.2' #服务器地址
set :user, 'deploy' #服务器部署用户
set :app_name, 'app_name' #应用程序名称, 一般可以用git项目名称
set :host_name, 'host.name' #nginx配置文件域名
set :git_server, 'github.com' #GIT服务器地址
set :git_repo, "git@#{git_server}:huaican/#{app_name}.git"
# nginx 屏蔽IE8以下的请求, 转跳到 /unsupported_browser.html
# set :supported_old_msie, false
###############
role :web, server_ip # Your HTTP server, Apache/etc
role :app, server_ip # This may be the same as your `Web` server
role :db, server_ip, :primary=>true
set :application, app_name
# #### 服务器环境 ####
set :rvm_path, "/usr/local/rvm"
set :rvm_bin_path, "/usr/local/rvm/bin"
set :deploy_via, :remote_cache
set :use_sudo, false
set :default_run_options, {:pty => true}
set :ssh_options, {:forward_agent => true}
set :rails_env, 'production'
set :keep_releases, 5 # keep only the last 5 releases
# 版本控制
set :scm, :git
set :repository, git_repo
set :branch, fetch(:branch, "master")
if branch == 'online'
set :deploy_to, "/home/#{user}/apps/#{application}"
else
set :deploy_to, "/home/#{user}/apps/#{application}_#{branch}"
end
# load recipes
require 'capistrano/recipes/base'
require 'capistrano/recipes/setup'
require 'capistrano/recipes/unicorn'
require 'capistrano/recipes/nginx'
# 开始unicorn进程数
set :unicorn_workers, 1
# 更改维护页面模板地址
# set :maintenance_template_path, File.expand_path("../recipes/templates/maintenance.html.erb", __FILE__)
# # delayed_job
# require "delayed/recipes"
# after "deploy:stop", "delayed_job:stop"
# after "deploy:start", "delayed_job:start"
# after "deploy:restart", "delayed_job:restart"
# 强制重启unicorn
after "deploy:restart", "unicorn:stop"
after "deploy:restart", "unicorn:start"
# 重启时开启 维护界面
before "deploy:restart", "deploy:web:disable"
after "deploy:restart", "deploy:web:enable"
after "deploy", "deploy:cleanup"
namespace :deploy do
# 其他命令
end
5. 修改部署变量
set :server_ip, '192.168.0.2' #服务器地址
set :user, 'deploy' #服务器部署用户
set :app_name, 'app_name' #应用程序名称, 一般可以用git项目名称
set :host_name, 'host.com' #nginx配置文件域名
set :git_server, 'git.inspiry.cn' #GIT服务器地址
set :git_repo, "git@#{git_server}:rails/#{app_name}.git"
6. 提交并部署
git add .
git commit -m '更新部署脚本'
git push origin master
# 设置服务器相关环境, 该操作会将 config/database.yml 上传到服务器, 操作前需修改好database.yml配置, 不需要提交到版本控制
cap deploy:setup
cap deploy
# 到线上服务器重启nginx
sudo /etc/init.d/nginx restart
