Question

尝试在Capistrano上部署3.我正在使用NGINX，RVM，Passenger，Rails 4.我的部署正在运行，但我需要手动重启NGINX - 这是部署结束时的错误：

    DEBUG [c4e821bc] Command: ~/.rvm/bin/rvm default do passenger -v
DEBUG [c4e821bc]    Phusion Passenger version 5.0.6
DEBUG [c4e821bc]    
DEBUG [c4e821bc]    "Phusion Passenger" is a trademark of Hongli Lai & Ninh Bui.
DEBUG [c4e821bc] Finished in 0.981 seconds with exit status 0 (successful).
 INFO [5082ae94] Running ~/.rvm/bin/rvm default do passenger-config restart-app /home/deploy/skilltry --ignore-app-not-running on 104.237.158.232

DEBUG [5082ae94]    *** ERROR: You are not authorized to query the status for this Phusion Passenger instance. Please try again with 'rvmsudo'.
cap aborted!

我在这里尝试过修复： https://github.com/capistrano/passenger/issues/2

Use visudo to edit the file (so if you mess up you have the chance to re-edit the file), at the end of the file (*) add the following:

deployuser    ALL=(root) NOPASSWD: /usr/bin/passenger-config

这没什么区别

在这里： How can I get passenger-config restart-app to work?

但是我得到一个我无法进入的提示：

[sudo] password for deploy:

查看gems / capistrano-passenger-0.0.5 / lib / capistrano / tasks / passenger.cap文件，它包含以下默认值：

  task :defaults do
    set :passenger_roles, :app
    set :passenger_restart_runner, :sequence
    set :passenger_restart_wait, 5
    set :passenger_restart_limit, 2
    set :passenger_restart_with_sudo, false
    set :passenger_environment_variables, {}
    set :passenger_restart_command, 'passenger-config restart-app'
    set :passenger_restart_options, -> { "#{deploy_to} --ignore-app-not-running" }
    set :passenger_rvm_ruby_version, ->{ fetch(:rvm_ruby_version) }
    if Rake.application.tasks.collect(&:to_s).include?("rvm:hook")
      before :'rvm:hook', :'passenger:rvm:hook'
    end
    if Rake.application.tasks.collect(&:to_s).include?("rbenv:map_bins")
      before :'rbenv:map_bins', :'passenger:rbenv:hook'
    end
  end

我能够将以下内容添加到deploy.rb以覆盖乘客实例的重启方式：

set :passenger_restart_command, 'sudo passenger-config restart-app'

您应首先验证/ etc / sudoers配置是否允许以root身份执行该命令的无密码执行。

当我尝试部署时，我也遇到了*** ERROR: You are not authorized to query the status for this Phusion Passenger instance. Please try again with 'sudo'.错误。我发现使用了capistrano-passenger宝石，可以选择解决这个问题：

# add this to config/deploy.rb
set :passenger_restart_with_sudo, true # default false

您可以阅读docs以查看其他选项。

可能的问题：

Nginx配置指向Capistrano用户没有访问权限的目录。
Nginx配置未监听您在Capistrano配置中设置的域。

Passenger是“进程管理器”，使用Nginx来管理往返于这些进程的http流量。

确保您的虚拟服务器指向Capistrano用户拥有的目录，并且虚拟服务器正在侦听Capistrano配置中存在的同一域。

一个例子：

假设您要部署到/home/my_user/my_app_path，则应将my_user设置为Capistrano用户以部署应用程序。

还要假设您的域为my_app.com，请确保Capistrano和Nginx配置均一致。

# Capistrano configuration
server "my_app.com", user: "my_user", roles: %w{app web db}

# Nginx configuration
server {
  listen 80;
  server_name my_app.com;
  root /home/my_user/my_app_path/current/public;
  passenger_ruby /home/my_user/.rbenv/shims/ruby;
  passenger_enabled on;
  passenger_min_instances 2;
  passenger_max_requests 5000;

  rails_env production;

  #... some more config settings

}
passenger_pre_start http://my_app.com;

Capistrano 3无权查询此Phusion Passenger实例的状态
