Rails Nginx Passenger 无法签出会话，因为发生生成错误

2024-02-24

我有一个 Rails 3.2.14 应用程序，可以在生产服务器上正常部署和运行。我正在努力将其部署到另一台服务器以在投入生产之前测试更改。我正在运行最新版本的 Passenger/nginx 并使用 Capistrano 2.12.0 和 Ruby 1.9.3-p194，因为这是一个遗留应用程序，我正在尝试模仿环境。

我可以毫无问题地部署应用程序，但它不会生成乘客并启动应用程序。

这是我在 /var/log/nginx/error.log 中遇到的错误之一

我注意到有关捆绑器的错误，但我确实安装了捆绑器 gem，这是我作为部署用户或根用户运行的输出：

这是我的 capistrano deploy.rb 以防万一它有帮助（注意，在生产服务器上工作，但是当我将 IP 更改为临时服务器时，它会部署但不运行 rake 任务或每当 gem 设置 crontab 时）：

require "bundler/capistrano"
set :whenever_command, "bundle exec whenever"
require "whenever/capistrano"

server "72.14.181.01", :web, :app, :db, primary: true

set :application, "appname"
set :user, "deploy"
set :deploy_to, "/home/#{user}/#{application}"
#set :deploy_via, :remote_cache
set :use_sudo, false
set :rails_env, "production"


set :scm, "git"
set :repository, "[email protected] /cdn-cgi/l/email-protection:appguy/#{application}.git"
set :branch, "master"


default_run_options[:pty] = true
ssh_options[:forward_agent] = true

after "deploy", "deploy:cleanup" # keep only the last 5 releases
after "deploy:update", "gps_listener:restart"

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end
  desc "reload the database with seed data"
  task :seed do
    run "cd #{current_path}; bundle exec rake db:seed RAILS_ENV=#{rails_env}"
  end
end

namespace :gps_listener do
  task :start do
    run "#{sudo} start app-gps"
  end

  task :stop do
    run "#{sudo} stop app-gps"
  end

  task :restart do
    run "#{sudo} stop app-gps && sleep 1 && #{sudo} start app-gps"
  end
end

task :after_update_code do
  run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
  run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake gps:listen"
end

我承认，自从我不得不引导新服务器以来已经有很长一段时间（1-2年）了，因此使用新版本的passenger/nginx重新创建这个遗留应用程序被证明是很麻烦的。我不确定这是乘客本身的问题还是红宝石的问题。

顺便说一句，这是我的 nginx 乘客配置：

/etc/nginx/nginx.conf

   passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
   passenger_ruby /home/deploy/.rbenv/shims/ruby;

这是我的默认虚拟主机 /etc/nginx/site-available/default

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        server_name prod.hcems.com;
        passenger_enabled on;
        rails_env    production;
        root         /home/deploy/exigencad/current/public;

        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
}

看来问题出在我的 .bashrc 文件上。

我在文件底部有以下内容：

if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    . /etc/bash_completion
fi
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"

这没有设置我的 rbenv 环境变量。一旦我将它移动到 .bashrc 的顶部，我就可以部署而不会出现错误。乘客现在启动应用程序。

我的每当 gem 似乎不起作用（设置我的 crontab 来执行 rake 任务），但我会就此提出另一个问题。
