问题描述
我在我的application.yml中设置端口为3000(figaro管理env变量)
rails s
使用端口3000
但是当我运行 foreman start
(按照Heroku的建议)我得到以下输出
14:53:23 web.1 |以pid开头24425
14:53:23 web.1 | [24425] Puma以群集模式启动...
14:53:23 web.1 | [24425] *版本2.11.1(ruby 2.2.0-p0),代号:Intrepid Squirrel

14:53:23 web.1 | [24425] *预加载应用程序
14:53:24 web.1 |警告:跳过PORT键。已经在ENV中设置。
14:53:25 web.1 | [24425] *在tcp上收听://0.0.0.0:5000
14:53:25 web.1 | [24425]使用Ctrl-C停止
14:53:25 web.1 | [24425] - 工人0(pid:24426)启动,阶段:0
14:53:25 web.1 | [24425] - Worker 1(pid:24427)booted,phase:0
Procfile
web:bundle exec puma -C config / puma.rb
config / puma.rb
workers Integer(ENV ['WEB_CONCURRENCY'] | | 2)
threads_count = Integer(ENV ['MAX_THREADS'] || 5)
线程threads_count,threads_count

端口ENV ['PORT'] || 3000
环境ENV ['RACK_ENV'] || 'development'
on_worker_boot do

end
config / application.yml
PORT:3000
- Rails 4.2.0
- 工头0.78.0
- Ruby 2.2.0p0
- 美洲狮2.11.1
然后你会发现端口神秘地设置为5000,即使它不在你的ENV中。
固定在底部。 p>
puma_port = ENV ['PORT'] || 3000
把 ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
把 puma_port是#{puma_port}
把ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
打印出来
16:49:28 web.1 | ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
16:49:28 web.1 | puma_port is 5000
ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
然后放置这条线在你的Procfile中(不是你用于Heroku的那个),我有一个叫做 Procfile.dev
web:PORT = 3000 bundle exec puma -C config / puma.rb
我用这个命令运行它:
foreman start -f Procfile.dev
I set the port as 3000 in my application.yml (figaro managing env variables)rails s
uses port 3000but when I run foreman start
(as recommended by Heroku) I get the following output
14:53:23 web.1 | started with pid 24425

end

- Foreman 0.78.0

- Puma 2.11.1
Mystery on the puma port solved.
Put this print in your config/puma.rb
Then you'll see that somehow the port is mysteriously set to 5000 even though it is not in your ENV.
Fix at bottom.
puma_port = ENV['PORT'] || 3000
puts "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ"
puts "puma_port is #{puma_port}"
puts "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ"
That prints out
16:49:28 web.1 | ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
16:49:28 web.1 | puma_port is 5000
ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
Then place this line in your Procfile (not the one you use for Heroku). I've got one called Procfile.dev
web: PORT=3000 bundle exec puma -C config/puma.rb
And I run it with this command:
foreman start -f Procfile.dev
