Question

几天前，我从 Mac 更改为 Linux (Ubuntu)，并从我在 GitHub 的团队项目中克隆了 repo。 （在此之前它与 Mac 一起工作）。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

但它向我显示了这些错误。

[3217] Puma starting in cluster mode...

然后我尝试运行

bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001

但是服务器没有运行就立即停止。

[3263] Puma starting in cluster mode...

[3263] * Preloading application
[3263] * Listening on tcp://127.0.0.1:3001
[3263] Use Ctrl-C to stop

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

喜欢

lsof -wni tcp:3000

但没有显示任何内容让我终止 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]
• 彪马版本 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

您似乎正在端口3000 上运行另一个程序。运行lsof -i:3000 并在命令有结果时使用kill 命令停止它。
