Question

我几天前已经从Mac更改为Linux（Ubuntu），我从GitHub的团队项目中克隆了该存储库。 （它在Mac之前就可以使用）。但是现在，我遇到了这个问题。

我试图通过运行在本地Unix套接字（3000）上启动服务器>

bundle exec puma
但是它向我显示了这些错误。

然后我尝试运行

bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001
但是服务器不运行就立即停止。

我也尝试过这篇文章中给出的方法：Address already in use - bind(2) (Errno::EADDRINUSE)

赞

lsof -wni tcp:3000
但没有任何资料显示我可以终止Pid进程。

有人可以帮忙吗？

这些是我正在使用的软件版本：

• Ubuntu 18.04 LTS
• Ruby 2.6.5p114（2019-10-01修订版67812）[x86_64-linux]
• Puma版本4.3.3

这是config / puma.rb中的代码

# vars
app_dir = File.expand_path("../..", __FILE__)
shared_dir = "#{app_dir}/shared"

# Specifies the `environment` that Puma will run in.
environment ENV.fetch("RACK_ENV") { "production" }

# pidfile and state
pidfile "#{shared_dir}/pids/puma.pid"
state_path "#{shared_dir}/pids/puma.state"

# Threads for serving requests
threads 1, 16

# Workers (cpu cores)
workers ENV.fetch("WEB_CONCURRENCY") { 1 }
preload_app!

# Unix socket to for nginix reverse proxy
bind "unix://#{shared_dir}/sockets/puma.sock"

# Port for local server use
port ENV.fetch("PORT") { 3000 }

# Debugging

# Logging
stdout_redirect "#{shared_dir}/log/puma.stdout.log", "#{shared_dir}/log/puma.stderr.log", true

activate_control_app

rackup "#{app_dir}/config.ru"

似乎您正在端口3000上运行另一个程序。运行lsof -i:3000，并在命令产生某些结果时使用kill命令将其停止。
