[Supervisor-users] running exec from php script within supervisor process

[Rolando Bermúdez Peña]

Hello all,

I have configured supervisor the latest version, to run a php script like
this:

...
command=php /path/to/the/script.php
...

But in that script i execute the function exec to run other processes
within the php script, in the error log that i have configured for that
program supervisor shows

sh: 1: commandname: not found

commandname is the one that i try to execute using exec within the php
script.
And of course the commandname exists and runs fine using the same user
supervisor uses.

Any ideas of how can get this to work?
Thanks in advance.

Hi Rolando,

That would be because PHP’s exec function is starting sh as the shell to
execute your command (hence the “sh: “ in the output), and this shell does
not have an environment setup like your current login shell.

Try running env in your login shell and see the output. Then run echo
exec('env'); via your PHP script and see how little there is :)

To fix it try using absolute paths to all programs called via exec - like
/usr/local/bin/pip as opposed to just pip.

Cheers
