php - 从 ftp 或 php 运行 Bash 文件 (.sh)

Question

让我承认，我从来没有从 php 运行 bash 文件...虽然我尝试使用谷歌搜索并使用 shell_exec，但我无法执行此操作& system()

我得到了一个 bash 脚本，它取回了 magento db，文件名为 backu.sh .该文件位于 magento root /var/www/html/backup.sh , 我怎样才能运行这个文件？

到目前为止我已经尝试过了

$output=shell_exec('sh backup.sh >/dev/null &' );
echo "<pre>$output</pre>";

但它没有显示任何内容，我也看不到生成的文件...我的 bash 脚本看起来像

`#!/bin/sh

请帮忙...

谢谢..

尝试:

$output=shell_exec('/path/to/sh /var/www/html/backup.sh' ); 
echo "<pre>$output</pre>";

通常，/path/to/sh是/bin/sh。

此外，您还可以在 backup.sh 脚本的末尾添加这一行:

echo "backup.sh has been executed" >> /var/www/html/backupstatus.txt

这样，如果您的脚本已成功执行，将创建一个名为 backupstatus.txt 的文件，其内容填充有 “backup.sh has been executed” .
