使用领班启动时，Rails服务器挂起 [英] Rails server hangs when started with foreman

问题描述

这是我的Procfile的样子：

Here's what my Procfile looks like:

web: bundle exec rails server thin -p $PORT -e $RACK_ENV
worker: bundle exec rake jobs:work

我打算添加一个辅助进程，因为我希望运行一些后台作业。我正在按照这些说明

I intend to add a worker process because I wish to run some background jobs. I'm following these instructions

这是我注意到的：

• 如果工人是单独启动的，则不会遇到任何问题。


• 当我将第二行保留在Procfile中并且不进行任何更改时，rails服务器会处理几个请求并在此之后挂起


• 如所述这里，我添加了 STDOUT.sync = true 到config / environments / development.rb并在rails控制台中进行了验证。没用。


• 将log / development.log尾巴化，并将其与由领班输出到shell的东西进行比较，并注意到两者都匹配了两个请求，然后领班停止打印出东西到外壳-下一个请求将挂起


• 我使用foreman.pkg更新了工头，如前所述此处，并与[6]进行了验证


• 有人提到在这里，这可能是由于调试错误的语句引起的。我没有使用调试器，而且我的Gemfile.lock中没有撬动的宝石或ruby-debug的宝石。


• 我相信症状类似于与此相关的未答复的问题

• No problems encountered if the worker is started separately.
• When I keep the second line in the Procfile and don't not change anything else, the rails server serves a couple of requests and hangs after that
• As mentioned here , I've added STDOUT.sync = true to config/environments/development.rb and verified the same in the rails console. Did not work.
• Tailed log/development.log and compared it against the stuff that foreman outputted to the shell and noticed that both matched for a couple of requests and then foreman stopped printing out stuff to the shell - the next request would then hang
• I updated foreman using foreman.pkg as mentioned here and verified the same with [6]
• It was mentioned here that this might be caused due to a stray debug statement. I'm not using the debugger and I do not have the pry gem or the ruby-debug gem in my Gemfile.lock
• I believe the symptoms are similar to this related unanswered question

请帮助！

[6]：

which foreman
/usr/bin/foreman
ls -lah /usr/bin/foreman  # checked the updated date

TL ; DR：安装gem，不要使用foreman.pkg

TL;DR: Install the gem, don't use foreman.pkg
