Dotcloud nodejs supervisord.conf不工作 [英] Dotcloud nodejs supervisord.conf not working

问题描述

我一直在试图让我的nodejs服务器进程受到主管的监视，但是我有使supervisord.conf工作的问题。当我部署时，我收到以下错误：

I've been trying to get my nodejs server process to be monitored by supervisor, however I'm having issues getting supervisord.conf to work. When I deploy, I get the following error:

WARNING: The service crashed at startup or is listening to the wrong port. It failed to respond on port "node" (42801) within 30 seconds. Please check the application logs.

然而，当我进入dotcloud服务器并手动启动nodejs进程时，它运行正常，表示该主管无法启动节点实例。

However when I ssh into the dotcloud server and manually start the nodejs process, it runs just fine, indicating that supervisor is failing to start the node instance.

我的supervisord.conf如下所示：

My supervisord.conf looks like this:

[program:node]
command = node /home/dotcloud/current/app/server.js
autostart=true
autorestart=true

我的目录结构如下：

.dotcloudignore
dotcloud.yml
.gitignore
app/
app/package.json
app/server.js
app/supervisord.conf

在这一点上，我看不到我做错了什么这似乎与这里所列出的目录结构相同，所以我是对于什么是解决方案是失败的。任何想法？

At this point, I can't see what I'm doing wrong, as this appears to be the same directory structure as outlined here, so I'm kind of at a loss as to what the solution is. Any ideas?

编辑：

尝试 supervisorctl状态我得到以下内容：

node                             FATAL      Exited too quickly (process log may have details)

我发现在/ var / log / supervisor中，我收到以下错误消息：

I've found that in /var/log/supervisor, I'm getting the following error message:

module.js:337
    throw new Error("Cannot find module '" + request + "'");
          ^
Error: Cannot find module '/home/dotcloud/current/app/server.js'
    at Function._resolveFilename (module.js:337:11)
    at Function._load (module.js:279:25)
    at Array.0 (module.js:484:10)
    at EventEmitter._tickCallback (node.js:190:38)

我不知道是什么导致的。

I'm not sure what is causing this.

推荐答案

调查问题后，看起来这个问题来自于 dotcloud.yml 指定 approot的事实：应用。在这种情况下，请注意：

After investigating the issue, it looks like the issue came from the fact that dotcloud.yml specified approot: app. In that case, it is useful to note that:

• / home / dotcloud / code 将指向整个代码存储库;


• / home / dotcloud / current 将指向审核（更具体地说， code> / home / dotcloud / current 将是一个符号链接，在这种情况下， code / app li>
  

• /home/dotcloud/code will point to the whole code repository;
• /home/dotcloud/current will point to the approot (more specifically, /home/dotcloud/current will be a symlink to the approot, i.e. code/app in that case).

因此， supervisord.conf 不应包含：

command = node /home/dotcloud/current/app/server.js

但是，而是：

command = node /home/dotcloud/current/server.js

Node.js中的关键是自己记录，因为Node.js抱怨无法找到 /home/dotcloud/current/app/server.js 。

The key was in the Node.js logs themselves, since Node.js was complaining about being unable to locate /home/dotcloud/current/app/server.js.
