我在 aws ec2 上的生产服务器上遇到了一个非常复杂的问题。

当我尝试启动 puma 服务时，它返回一个错误，并且 journalctl -e 向我显示：

我在项目中的 puma.rb：

max_threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }
min_threads_count = ENV.fetch("RAILS_MIN_THREADS") { max_threads_count }
threads min_threads_count,max_threads_count

port        ENV.fetch("PORT") { 3000 }
environment ENV.fetch("RAILS_ENV") { "development" }
pIDfile ENV.fetch("PIDfile") { "tmp/pIDs/server.pID" }

plugin :tmp_restart

我的 deploy.rb：

set :rbenv_ruby_string,'2.7.1'

set :application,"my-project"
set :repo_url,"git@my-repo"

shared_path = "/home/ubuntu/apps/my-project/shared"
release_path = "/home/ubuntu/apps/my-project"

namespace :puma do
  desc 'Create DirectorIEs for Puma PIDs and Socket'
  task :make_dirs do
    on roles(:app) do
      execute "mkdir #{shared_path}/tmp/sockets -p"
      execute "mkdir #{shared_path}/tmp/pIDs -p"
    end
  end

  before 'deploy:starting','puma:make_dirs'
end

namespace :deploy do
  desc "Make sure local git is in sync with remote."
  task :check_revision do
    on roles(:app) do

      # Update this to your branch name: master,main,etc. Here it's main
      unless `git rev-parse head` == `git rev-parse origin/master`
        puts "WARNING: head is not the same as origin/master"
        puts "Run `git push` to sync changes."
        exit
      end
    end
  end

  desc 'Initial Deploy'
  task :initial do
    on roles(:app) do
      before 'deploy:restart','puma:start'
      invoke 'deploy'
    end
  end

  desc 'Restart application'
    task :restart do
      on roles(:app),in: :sequence,wait: 5 do

set :puma_preload_app,true
set :puma_worker_timeout,nil
set :puma_init_active_record,true

还有我的 puma 服务：

[Unit]
Description=Puma http Server
After=network.target


[Service]
# Foreground process (do not use --daemon in ExecStart or config.rb)
Type=simple
# Preferably configure a non-privileged user
User=ubuntu
Group=ubuntu
# Specify the path to your puma application root
WorkingDirectory=/home/ubuntu/apps/my_project/current
# Helpful for deBUGging socket activation,etc.
Environment=RAILS_ENV=production


# The command to start Puma
ExecStart=/home/ubuntu/.rbenv/shims/bundle exec puma -C /home/ubuntu/apps/my_project/current/config/puma.rb

Restart=always


[Install]
WantedBy=multi-user.target

我的 Nginx 运行正常。但是只有我的 puma 服务上不去。

在路径“.rbenv/shims/我没有看到美洲狮，我不知道为什么：
