在php .sh文件中执行

Question

我试图在php中执行一个.sh文件

该文件位于/home/update.sh

#!/bin/bash

/usr/bin/rsync -zaP '-e ssh -i /home/id_rsa_ws -v -p 6633' --del /var/www root@xxx.xxx.xxx:/var/

执行此文件运行良好：

cd /home/; ./update.sh;

问题是：我需要在php中执行此文件

我已经在php中尝试过的内容：

1-什么也没发生。

    $contents = file_get_contents('/home/distribute.sh');
    echo '<pre>';
    echo shell_exec($contents);

我也试过了：

2。

    exec("cd /home/;./update.sh 2>&1",$o,$return);
    print_r($o);
    print_r($return);

非常感谢[ https://stackoverflow.com/users/1491895/barmar]

在Barmar建议之后，我更改了以下内容：

答：我将ssh密钥移至/var/www/.ssh

B.我更改了.sh文件中的命令，我添加了两个参数

    -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null


    /usr/bin/rsync -zaP '-e ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i /var/www/.ssh/id_rsa_ws -v -p 6633' --del /var/www root@xxx.xxx.xxx.xxx:/var/
