ssh-agent和crontab的 - 有什么好办法让这些见面吗？ [英] ssh-agent and crontab -- is there a good way to get these to meet?

问题描述

我写了一个简单的脚本，它每晚寄出SVN活动日志给开发者。到现在为止，我已经在同一台计算机的svn库上运行它，所以我没有担心验证，我可以只使用SVN的文件：///地址风格

I wrote a simple script which mails out svn activity logs nightly to our developers. Until now, I've run it on the same machine as the svn repository, so I didn't have to worry about authentication, I could just use svn's file:/// address style.

现在我在家用计算机上运行脚本，访问远程仓库，所以我不得不改变SVN + SSH：//路径。使用ssh-键很好地建立了，我从来没有要为在正常情况下访问svn库输入密码。

Now I'm running the script on a home computer, accessing a remote repository, so I had to change to svn+ssh:// paths. With ssh-key nicely set up, I don't ever have to enter passwords for accessing the svn repository under normal circumstances.

不过，crontab中没有访问我的SSH密钥/ SSH代理。我读过有关这个问题在网络上几个地方，而且它也提到在这里，没有分辨率：

However, crontab did not have access to my ssh-keys / ssh-agent. I've read about this problem a few places on the web, and it's also alluded to here, without resolution:

我的解决办法是将它添加到脚本的顶部：

My solution was to add this to the top of the script:

### TOTAL HACK TO MAKE SSH-KEYS WORK  ###
eval `ssh-agent -s`

这似乎MacOSX的10.6下工作。

This seems to work under MacOSX 10.6.

我的问题是，如何可怕的是这一点，有没有更好的办法？

My question is, how terrible is this, and is there a better way?

推荐答案

在运行ssh代理-s，它将启动一个后台进程，你会需要稍后将其杀死。因此，最低是你的黑客更改为类似：

When you run ssh-agent -s, it launches a background process that you'll need to kill later. So, the minimum is to change your hack to something like:

eval `ssh-agent -s` 
svn stuff
kill $SSH_AGENT_PID

不过，我不明白这是如何破解工作。只需运行一个代理还没有运行的ssh-ADD将不会加载任何按键。也许MacOS的ssh-agent的行为是不同于它的<一个href=\"http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man1/ssh-agent.1.html\">manual页面说它。
