Using CentOS 6.3x64.
I'm trying to run
wkhtmltopdf (from here) from a PHP script. I can successfully call
wkhtmltopdf-amd64 directly via SSH. But when calling it from PHP via
exec, it always fails with exit code 127. The path is correct, so that isn't the issue. I can successfully use
exec to call
id etc, so the problem seems to be specific to calling
I would presume this somehow relates to permissions, but I'm not sure what steps to take. I've tried
apache:apache and other ownerships on the program and it has 755 permissions.
Thanks for any guidance!
Sorry for not clarifying further above -- I have confirmed the issue does not relate to the path to the program. I'm using the full absolute path. I've confirmed that the exact same command can be run from the SSH line without problem (regardless of the
pwd). I've also created a shell script:
#!/bin/sh echo 'hello, world!'
I can call this script via
exec and it works properly. However, if I modify it to be
#!/bin/sh echo 'hello, world!' /full/path/to/wkhtmltopdf-amd64 'http://www.google.com/' /full/path/to/output.pdf
it then fails and returns the exit code 127.
