Supervisord “exit status 1 not expected” running php script

Question

I'm having issue try to configure supervisor to run a php script. Running supervisor in debug mode gives me this:

2015-03-09 08:53:06,342 INFO supervisord started with pid 2030
2015-03-09 08:53:06,358 INFO spawned: 'worker1' with pid 2031
2015-03-09 08:53:06,423 INFO exited: worker1 (exit status 1; not expected)
2015-03-09 08:53:06,424 INFO received SIGCLD indicating a child quit
2015-03-09 08:53:07,440 INFO spawned: 'worker1' with pid 2032

2015-03-09 08:53:09,604 INFO spawned: 'worker1' with pid 2033
2015-03-09 08:53:09,756 INFO exited: worker1 (exit status 1; not expected)
2015-03-09 08:53:09,758 INFO received SIGCLD indicating a child quit
2015-03-09 08:53:12,775 INFO spawned: 'worker1' with pid 2034
2015-03-09 08:53:12,973 INFO exited: worker1 (exit status 1; not expected)
2015-03-09 08:53:12,974 INFO received SIGCLD indicating a child quit
2015-03-09 08:53:13,976 INFO gave up: worker1 entered FATAL state, too many start retries too quickly

The supervisord configuration:

[program:worker1]
command=php myScript.php
directory=/home/path/to/script/
user=root
autostart=true
autorestart=true
stderr_logfile=/var/log/worker1.err.log
stdout_logfile=/var/log/worker1.out.log
redirect_stderr=true
environment=PATH="/usr/bin"

For this test myScript.php just print out echo "test".PHP_EOL;

There are no logs reporting errors from php, and if I run the script thru cli it works as expected. The supervisord log just report the same output as debuggin.

I've also tried using absolute paths like /usr/bin/php /home/path/to/script/myScript.php but nothing changes.

File permission for myScript.php are set to -rwxrwxr-x 1 root apache

Really don't know what else i could check. Thanks for support!

UPDATE_1

I've also tried to monitor other program like /bin/cat or a bash script and works like a charm. The problem seems to be limited to php.

UPDATE_2

As N.B. pointed out in the comments i've changed the test script to look more like long-running-job:

while(true){
    echo "test".PHP_EOL;
    sleep(10);
}

Same as before, it enters in FATAL state.

have you tried the full path to script in the "command" line? — MegaAppBear
Yep, tried running it like: /usr/bin/php /home/path/to/script/myScript.php. No difference. — Luciano
redirect_stderr is redirecting to you stdout, I take it there's nothing in your stdout as well? — MegaAppBear

The only way I could reproduce this behaviour with exit code 1 is to use a invalid path to the file. So first please double check if the path is correct. But I think you have done this before.

I more assume that the file is located under your home directory and the root user is not able access and run it. So I would try to change the location of the script.

For testing, you can place your script under /tmp/myScript.php:

cp /home/path/to/script/myScript.php /tmp/myScript.php

and modify your supervisord config like this:

[program:worker1]
command=php myScript.php
directory=/tmp/
user=root
autostart=true
autorestart=true
stderr_logfile=/var/log/worker1.err.log
stdout_logfile=/var/log/worker1.out.log
redirect_stderr=true
environment=PATH="/usr/bin"

Now supervisored should be able to run your script.

If this is working, you should check which folder prevent root from accessing the script. This could be caused by an encypted (and mounted) folder (home dir?), or if the location is mounted from else where (samba, nfs ...). To solve the issue you can try to change the user from root to your user (I would not recommend this) or change the project location to another folder, which is not located under your home dir.
