php - 错误 : cannot open . git/FETCH_HEAD:使用 php 脚本进行 git pull 时权限被拒绝

Question

我为 git pull 疯狂的简单 php 脚本

<?php
$output = shell_exec("cd /var/www/domain.tld/html/test/ && git pull 2>&1");
echo "<pre>$output</pre>";

将其命名为 git.php 并给它 755

输出是

error: cannot open .git/FETCH_HEAD: Permission denied

但是当从终端尝试时

$ git pull
Already up-to-date.

我检查了目录所有权，我的用户是“精明的”

Answer 1

我通过以下方法解决了这个问题

第 1 步:将/home/savvy/.ssh 复制到/var/www/

# cp -R /home/savvy/.ssh /var/www/

第 2 步:将/var/www 目录提供给 www-data 用户

# chown -R www-data:www-data /var/www/

第 3 步:以 www-data 用户身份登录

$ su
Password: 
# su -s /bin/bash www-data

第 4 步:将存储库克隆到我的目录/var/www/domain.tld/html/test/

第 5 步:调用我已经创建的 git.php 文件 domain.tld/git.php

结果

From bitbucket.org:repo/test
8e9f67c..185cd9e  master     -> origin/master
