全新安装时出现流星抛出错误"意外的mongo退出代码为null。在起动"

标签: mongodb ubuntu meteor plex

我在全新的ubuntu安装上设置plex请求服务器(https://github.com/lokenx/plexrequests-meteor/blob/master/README.md)。

我开始下载似乎没有任何问题的流星curl https://install.meteor.com/ | sh。然后我克隆了plex-requests项目,并从该目录中运行meteor

这是生成的错误:

plex@johnpc:/home/plex/plexrequests-meteor$ meteor
[[[[[ /home/plex/plexrequests-meteor ]]]]]

=> Started proxy.
=> Started MongoDB.
Unexpected mongo exit code null. Restarting.

我想知道是否还有其他一些我缺少的依赖项,或者还有什么可能导致此问题。我的猜测是它可能是某种权限问题,因为我遇到过这个服务器上的少数几个,但我不知道在哪里。看起来好像在抛出错误的目录上权限是正确的。

plex@johnpc:/home/plex/plexrequests-meteor$ ls -al /var/lib/plexmediaserver

drwxr-xr-x  8 plex plex 4096 Nov 29 17:31 .

-rw-------  1 plex plex  638 Nov 29 17:17 .viminfo

另一个问题是我可能缺少依赖项 - 我安装了mongo以查看是否可以解决问题,但它似乎仍然存在。我尝试了建议here的解决方案,通过设置lang env变量并重置流星,没有任何解决问题的方法。想法?

下面显示的系统在我的macbook pro上完美运行,但是一旦我尝试在我的新ubuntu(Ubuntu 14.04 x64)盒子上重新创建它,就会出现这个问题。

另一种可能性是这可能与记忆有关。当内存耗尽时,我发现人们在网上与流星斗争。它似乎不会发生在我身上,但如果我对此错了,请纠正我。

根据我对拥有768MB内存的cloud9的经验,在流星运行几分钟并且内存已满后,我会得到同样的异常。

如果你想用流星进行开发,你需要的内存比现有的多得多。如果你只是想运行它,你可以构建应用程序并将其作为一个简单的节点应用程序运行,但MongoDB没有这个,你需要添加额外的。
