[英]Command not found: PHP exec()
This is driving me crazy. 这真让我抓狂。 I need to have php execute a command to restart a script running in node. 我需要php执行一个命令来重启节点中运行的脚本。 I'm using a node app called forever to run said script. 我正在使用一个名为forever的节点应用来运行所述脚本。 The code is as follows: 代码如下:
<?php
echo '<pre>';
echo exec('sudo -u dalton forever restart botti.js 2>&1');
echo '</pre>';
?>
However, when I run that, I get sudo: forever: command not found
但是,当我运行它时,我得到sudo: forever: command not found
Next, I try which forever
and type forever
, both which give me: 接下来,我尝试which forever
和which forever
type forever
,这两个给我:
forever: /usr/local/bin/forever
I edit my code to: 我编辑我的代码:
echo exec('sudo -u dalton /usr/local/bin/forever restart botti.js 2>&1');
Edit: After a typo, the error is now: 编辑:输入错误后,错误现在是:
/usr/bin/env: node: No such file or directory
I'm at my wit's end. 我的智慧结束了。 Any ideas? 有任何想法吗?
As the forever
command only runs, when you give the full path, I suspect, that /usr/local/bin
is not in your PATH
environment variable, which contains all directories, that are searched for executable commands by default, separated by :
(I suspect you're on Linux, may differ for other OS) 由于forever
命令只运行,当你给出完整路径时,我怀疑, /usr/local/bin
不在你的PATH
环境变量中,它包含所有目录,默认情况下搜索可执行命令,用:
分隔:
我怀疑你在Linux上,可能与其他操作系统有所不同)
I suspect forever
calls /usr/bin/env node
. 我怀疑forever
调用/usr/bin/env node
。 The error from env
is probably caused by node
being outside your PATH
too. env
的错误可能是由node
在PATH
之外引起的。
To set your PATH in php, use putenv('PATH=<your path here>');
要在php中设置PATH,请使用putenv('PATH=<your path here>');
eg to append /usr/local/bin
: 例如,添加/usr/local/bin
:
putenv('PATH=' . getenv('PATH') . ':/usr/local/bin')
This may also be a sudo
issue, try the -E
(preserve environment) switch. 这也可能是一个sudo
问题,尝试-E
(保护环境)切换。
弄清楚了,我还需要定义节点:
$asdf = system('sudo -E -u dalton /usr/local/bin/node /usr/local/bin/forever restart botti.js 2>&1');
Create a symbolic link for forever 永远创建一个符号链接
ln -s /usr/local/bin/forever /usr/bin/env/forever
And also for nodejs if incase it's still called "nodejs". 而对于nodejs,如果它仍然被称为“nodejs”。 Make it call as "node" 将其称为“节点”
ln -s /usr/bin/nodejs /usr/bin/node
I will solve the forever execution problem. 我将解决永远执行问题。
For php side, try with this 对于php端,请尝试使用此功能
echo shell_exec("your command sh");
