由于 Errno::EPERM，独角兽无法在 Vagrant 盒子上启动

问题描述

当我运行以下命令在我的 Vagrant 盒子 (ubuntu-12.04.2-server-i386) 上为 Sinatra 应用程序启动 Unicorn 时

When I run the following command to start Unicorn for a Sinatra app on my Vagrant box(ubuntu-12.04.2-server-i386)

sudo unicorn -c unicorn.rb -E development -D -l 0.0.0.0:8080

我在 Unicorn 日志中收到以下错误.

I get the following error in the Unicorn logs.

I, [2013-05-05T19:15:15.538805 #2357]  INFO -- : listening on addr=0.0.0.0:8080 fd=5
F, [2013-05-05T19:15:15.541673 #2357] FATAL -- : error adding listener addr=/home/vagrant/tmp/myapp/sockets/unicorn.sock
/home/vagrant/.rbenv/versions/1.9.3-p392/lib/ruby/gems/1.9.1/gems/unicorn-4.3.1/lib/unicorn/socket_helper.rb:140:in `initialize': Operation not permitted - "/home/vagrant/tmp/myapp/sockets/unicorn.sock" (Errno::EPERM)

我以 vagrant 用户身份登录并按照 http://recipes.sinatrarb 配置了 unicorn.rb.com/p/deployment/nginx_proxied_to_unicorn

I am logged in as the vagrant user and have configured the unicorn.rb as per http://recipes.sinatrarb.com/p/deployment/nginx_proxied_to_unicorn

@dir = '/home/vagrant/myapp/'

worker_processes 4
working_directory @dir

timeout 30

listen "#{@dir}tmp/sockets/unicorn.sock", :backlog => 64
pid "#{@dir}tmp/pids/unicorn.pid"

stderr_path "#{@dir}log/unicorn.stderr.log"
stdout_path "#{@dir}log/unicorn.stdout.log"

我已经查看了代码，但无法初始化以下内容

I have looked through the code and it fails to initialize the following

Kgio::UNIXServer.new('0.0.0.0:8080')

推荐答案

Unicorn 无法将 .sock 文件存储在 Virtual Box 共享文件夹中，因此您需要做的是从以下内容中修改套接字:

Unicorn can't store a .sock file on a Virtual Box Shared Folder, so what you'll have to do is modify for the socket from this:

listen "#{@dir}tmp/sockets/unicorn.sock", :backlog => 64

为此:

listen "/tmp/sockets/unicorn.sock", :backlog => 64

或 VBox 共享文件夹之外的其他位置.

Or some other location outside of the VBox shared folder.
