[英]Executing shell script using php
I have a shell script deploy.sh
that has the following content:- 我有一个shell脚本
deploy.sh
,它包含以下内容: -
echo "0 Importing the code"
eval "git pull -u origin master"
echo "1 Backing up existing data in database.."
// -- other code follows here
When I execute the script directly using the terminal, I get the following output:- 当我使用终端直接执行脚本时,我得到以下输出: -
0 Importing the code
remote: Counting objects: 5, done. remote: Compressing objects: 100% (2/2), done. remote: Total 3 (delta 1), reused 0 (delta 0) Unpacking objects: 100% (3/3), done. From bitbucket.org:user/repo * branch master -> FETCH_HEAD Updating db13xxx..6705xxx
1 Backing up existing data in database..
This is correct. 这是对的。 However, I wrote a PHP script with which I can invole the deploy.sh script over http.
但是,我编写了一个PHP脚本,我可以通过http来调用deploy.sh脚本。 Content of this php page is as follows:-
这个php页面的内容如下: -
$output = `./deploy.sh`;
echo '<pre>', $output, '</pre>';
When I invoke this php file through the browser, the shell script is in fact getting invoked and I'm getting the following output:- 当我通过浏览器调用这个php文件时,shell脚本实际上被调用了,我得到以下输出: -
0 Importing the code 1 Backing up existing data in database..
The problem is that the eval "git pull -u origin master"
command didnt get executed and its output is not shown. 问题是
eval "git pull -u origin master"
命令没有执行,它的输出也没有显示。 Any idea what the problem is? 知道问题是什么吗?
This works 这有效
<?php
$output = shell_exec('sh deploy.sh');
echo "$output";
?>
Before that make sure that file has chmod 777 permission. 在此之前,请确保该文件具有chmod 777权限。
You should try to avoid running shell commands in php. 你应该尽量避免在php中运行shell命令。
Having said that, try this: 话虽如此,试试这个:
$output = shell_exec('./deploy.sh');
echo "<pre>".$output."</pre>";
As per: http://www.php.net/manual/en/function.shell-exec.php 根据: http : //www.php.net/manual/en/function.shell-exec.php
One thing you can do with the exec()
function is to pass two optional values for more insight. 使用
exec()
函数可以做的一件事是传递两个可选值以获得更多洞察力。
Here's some code I use to test shell scripts from a web interface. 这是我用来从Web界面测试shell脚本的一些代码。
<?php
require_once(__DIR__.'/../libs/Render.php');
error_reporting(E_ALL);
//Initialize and Run Command, with a little trick to avoid certain issues
$target='cd ../../your/relative/path && ./CustomScript.sh';
$outbuf=exec($target,$stdoutbuf, $returnbuf);
//Structure
$htm= new renderable('html');
$html->children[]= $head= new renderable('head');
$html->children[]= $body= new renderable('body');
$body->children[]= $out= new renderable('div');
$body->children[]= $stdout= new renderable('div');
$body->children[]= $returnout= new renderable('div');
//Value
$out->content= 'OUTPUT: '.$outbuf;
$stdout->content= 'STDOUT: '.var_export($stdoutbuf,true);
$returnout->content= 'RETURN: '.$returnbuf; //127 == Pathing problem
//Output
print_r($html->render());
?>
File is using the renderable class from the project I use this in, but you can put the string output wherever you are using it or echo/print_r()
just as well. File正在使用我在其中使用的项目中的可渲染类 ,但您可以将字符串输出放在您使用它的任何位置或者
echo/print_r()
。 Also make sure you're not in safe mode by running phpinfo(); 还要确保运行phpinfo()时不处于安全模式; lots of folks having that issue.
很多人都有这个问题。
Additionally, there's no reason you should avoid using shell scripts in PHP. 此外,没有理由避免在PHP中使用shell脚本。 PHP being a scripting language, it is quite thrifty at aggregating many shell scripts to allow higher-level administration.
PHP是一种脚本语言,在聚合许多shell脚本以允许更高级别的管理方面非常节俭。
PHP isn't only for 'web sites'. PHP不仅适用于'网站'。 Even then, exposing administrative scripts to web interfaces is quite useful in and of itself;
即便如此,将管理脚本暴露给Web界面本身也是非常有用的; occasionally this is even a project requirement.
偶尔这甚至是项目要求。
This is the correct code
这是正确的代码
<?php
$cmd = 'ifconfig'; // pass command here
echo "<pre>".shell_exec($cmd)."</pre>";
?>
