shell_exec和git pull [英] shell_exec and git pull

问题描述

我希望有人可以帮忙，我有一个PHP页面，它使用 shell_exec 来压缩目录并运行 git pull 来关闭最近的资料库更改。

I was hoping someone could help, I have a PHP page which uses shell_exec to zip up a directory and run git pull to bring down recent repository changes.

$op = shell_exec("cd /home/user/git/$repo/$dir/; zip -r /home/user/archives/$dir.$datestamp.zip $dir; cd /home/user/git/$repo/$dir/; git pull");

这个zip工作正常。如果我将 git pull 更改为例如 git log 或 git status - 在我的shell_exec中，这也适用，我可以看到日志文件。

The zip works fine. If I change git pull to for example git log or git status - within my shell_exec, this works also, and I can see the log file.

只是似乎不喜欢git pull。

Just doesn't seem to like git pull.

我看到另一个类似的帖子，但wasn不知道它是如何实现的>> Shell_exec with git pull？

I saw another similar post to this, but wasn't sure how it was achieved >> Shell_exec with git pull?

推荐答案

从您在评论中的描述看来，问题在于您的 apache 用户无法写入存储库，这在使用 git pull 时显然是必需的。你有两个行动方案：

From your description in the comments it seems that the problem is that your apache user cannot write to the repository, which is clearly required when you use git pull. You have two courses of action:

1. 设置Apache以作为另一个用户运行脚本（例如使用 suEXEC 在VirtualHost或通过用户目录）


2. 更改存储库的权限，使 apache 用户可以写入它

1. Setup up Apache to run the script as another user (e.g. using suEXEC either on a VirtualHost or via userdir)
2. Change the permissions on your repository so the apache user can write to it

您应仔细考虑这两种选择的安全含义，但第二种选择可能最容易的。如果你还没有这样的团队，你可以用以下方式创建它：

You should think carefully about the security implications of either choice, but the second option is probably easiest. If you don't already have such a group, you can create it with:

addgroup gitwriters

...然后将自己和Apache用户添加到此组中：

... and then add yourself and the Apache user to this group:

adduser [yourusername] gitwriters
adduser apache gitwriters

<然后你可以按照另一个问题来更改存储库上的权限。重申以下几点细微差别：

Then you can follow the instructions in another question to change the permissions on the repository. To reiterate those with some slight variations:

# Recursively, set the group ownership of every file and directory of your repository:
chgrp -R gitwriters /path/to/your/repo

# Recursively, make every file and directory of your repository readable and writable
# by the group:
chmod -R g+rw /path/to/your/repo

# Recursively, set the setgid of every directory in the repository.  The setgid bit
# on directories means that files created in the directory will have the same group
# ownership as the directory.  
find /path/to/your/repo -type d -print0 | xargs -0 chmod g+s

然后希望你的 git pull 应该可以工作。

Then hopefully your git pull should work.
