rails使用capistrano来部署和重新启动？
提问于 2015-12-11 03:15:35
我试着用capistrano来部署我的应用程序，所有的问题都是固定的，除了.
我无法在部署之后自动重新启动服务器，下面是我的代码：
宝石档案：
gem 'capistrano-rails', '~> 1.1.3'#, group: :development
gem 'capistrano', '~> 3.1'
gem 'capistrano-rbenv', '~> 2.0'
gem 'capistrano-bundler', '~> 1.1.2'
gem 'capistrano-passenger', '~> 0.1.1'
gem 'capistrano3-delayed-job', '~> 1.0'
gem 'capistrano3-nginx', '~> 2.0'capfile：
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rbenv'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
require 'capistrano/passenger'
require 'capistrano/delayed-job'
require 'capistrano/nginx'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }deploy.rb：
require "whenever/capistrano"
`ssh-add` # need this to make key-forwarding work
set :whenever_identifier, ->{ "#{fetch(:application)}_#{fetch(:stage)}" }
set :application, 'devops'
set :repo_url, 'mygit'
set :rbenv_type, :user
set :rbenv_ruby, "2.2.2"
set :rbenv_path, "/home/john/.rbenv"
set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec"
set :rbenv_map_bins, %w(rake gem bundle ruby rails)
set :rbenv_roles, :all
set :deploy_to, '/home/john/devops'
set :log_level, :debug
set :linked_dirs, fetch(:linked_dirs, []).push("bin", "log", "tmp/pids", "tmp/cache", "tmp/sockets", "vendor/bundle", "public/system") deploy.rb
namespace :deploy do
# I try following code:
#---
after :deploy, cap nginx:restart
run "sudo /etc/init.d/nginx restart"
run "touch tmp/restart.txt"
after :deploy, cap production passenger:restart
after :deploy, cap production deploy:restart
#---
# invoke 'delayed_job:restart'
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
within release_path do
execute :rake, 'cache:clear'
end
end
end
end当我在本地输入"touch tmp/restart.txt“(在帽生产部署之后)，我的页面不会随着修改而改变，我总是需要使用"sudo /etc/init.d/nginx重新启动”，如何解决这个问题？
我尝试这样做，但也没有响应(没有错误消息)：
after 'deploy:publishing', 'deploy:restart'
namespace :deploy do
desc "Restart application"
after :publishing, 'deploy:restart'
task :restart do
on roles(:app), in: :sequence, wait: 1 do
execute :touch, release_path.join("tmp/restart.txt")
end
end

要让乘客重新启动应用程序，您应该在服务器上使用touch/restart.txt，而不是本地的：
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Restarts Phusion Passenger
execute :touch, release_path.join('tmp/restart.txt')
end
end
end重新启动nginx本身是没有意义的，除非您正在升级乘客。
此外，重新启动并不是即时的，请求只有在启动后才被路由到新代码。
