I need to start OpenOffice server in background (if it's not instanciate) then do a file convertion with JODConverter.
The scenario is as follows :
- The user inputs a *.html file by a form.
- I get the file by the $_FILES variable in the PHP script corresponding to the form action
- I run a bash script with shell_exec, and pass the temp path to it, to access the file ine my bash script, then do the convertion
This is the PHP code :
$fichier = $_FILES['html_file'];
if($fichier) {
if(is_uploaded_file($fichier['tmp_name'])) {
if(move_uploaded_file($fichier['tmp_name'],"/var/www/test/doc/".$fichier['name'])) {
$output = shell_exec("./converter {$fichier['name']}");
echo $output;
}
}
}
The script "converter" code :
#!/bin/bash
fichier=$1
pid=$$
echo RUNNING sOFFICE :
SERVICE=soffice
if P=$(pgrep $SERVICE)
then
echo sOFFICE IS ALREADY RUNNING
else
echo sOFFICE WILL BE START WAIT 5s PLEASE
soffice --headless --accept="socket,host=127.0.0.1,port=8100;urp;" --nofirststartwizard &
sleep 5
fi
echo CONVERSION START
java -jar ./jodconverter/lib/jodconverter-cli-2.2.2.jar ./$1 ./$1.odt
echo CONVERSION END
My problem is in the first part of the bash script, when I try to run the sOFFICE server in background, this command blocks the final execution of the script, even with the use of &.
I've tried to run this script by the terminal, and it works perfectly.
So I think, the problem come with the php execution of the bash script. Have an idea ?
EDIT :
Solution found thanks to Jim Rubenstein response :
redirect the standard out and standard error streams
: Replace
soffice --headless --accept="socket,host=127.0.0.1,port=8100;urp;" --nofirststartwizard &
by
soffice --headless --accept="socket,host=127.0.0.1,port=8100;urp;" --nofirststartwizard > /dev/null 2> /dev/null &
