开源中国Git PUSH钩子部署PHP程序

我的代码托管在开源中国得Git库里，想使用Git钩子来实现程序的部署，写了一个程序接受钩子的post的数据，但是不能实现程序的部署。。代码如下：

public function index(){
        $logger = new KLogger(LOG_PATH.'KLogger');

        $web_root_dir = APP_PATH;  // /var/www/site

        if(IS_POST){
            $payload = $_POST;
            $payload = json_decode($payload['hook']);
            $logger->info('data from git post...', $payload); 

            // if (!empty($payload['password'])){
                $command = "cd {$web_root_dir} && git pull";
                $logger->info('enter if .....');
                $result = exec($command);
                $logger->info('command execute result...'.$result); 

            // }
        }

    }

在程序里记录了日志，能接收到post数据，但是命令执行不成功，下面是log的内容：

[2015-05-05 2:07:34.114928] [INFO] data from git post...

                )),
            )),
        ),
         'total_commits_count' => 1,
    ))

可能是权限问题

我一般不用钩子,麻烦还维护,需要部署的地方执行这个脚本

#! /bin/bash
while true
do
    git pull
    sleep 5
done

当然,如果你的程序还需要针对代码更新做一些其他操作,这个就不好用了.

贴自己写的一个简单的小脚本，配置一些信息既可以实现题主功能，能够简单的记录信息到log。
