use "wine" with php's shell_exec - php

I am currently trying to use a "wine" command from my PHP-Script.
If i execute this:
$shell = shell_exec("/usr/bin/wine --version");
All is working fine and WINE version is displayed in $shell.
But, if i try to make it like this:
$run = shell_exec("/usr/bin/wine ".$workdir."/bin/tool.exe -m ".$workdir."/bin/std.maps -a ".$workdir."/bin/alias.file -n ".$workdir."/files/".$project_name."/upload/dump.bin -o ".$workdir."/files/".$project_name."/maps/definitions.list");
Which results in:
$run = shell_exec("/usr/bin/wine /var/www/html/bin/tool.exe -m /var/www/html/bin/std.maps -a /var/www/html/bin/alias.file -n /var/www/html/files/1-59374-94700/upload/dump.bin -o /var/www/html/files/1-59374-94700/maps/definitions.list 2>&1");
I get the following output:
wine: chdir to /.wine : No such file or directory
What i am doing wrong? If i enter the command above directly to the shell, all is working fine. If i do it without /usr/bin/ in front of wine, the output's are the same.
Br, Chris

I haven't try it myself but I think it is because wine is run as different user with different environment settings. Try create .wine directory inside /var/www and make www-data user as owner of this directory and make /var/www/.wine HOME directory.
$run = shell_exec("HOME=/var/www/.wine /usr/bin/wine ".$workdir."/bin/tool.exe -m ".$workdir."/bin/std.maps -a ".$workdir."/bin/alias.file -n ".$workdir."/files/".$project_name."/upload/dump.bin -o ".$workdir."/files/".$project_name."/maps/definitions.list");

Passing a variable from PHP to ubuntu

I want to run a script on my ubuntu server with a variable from php in it.
Here are some of the things i've tried to pass a variable to ubuntu...
shell_exec('vpsName=HI3');
vpsName=`mysql -D jake_db -h 127.0.0.1 -u jake -pXXXXXXX -se "SELECT vpsName FROM reinstalls WHERE status = 'pending'"`;
The final way in which i thought I could fix it was to avoid running the script through ubuntu all together and run it from shell_exec(); but it fails on running the guestfish commands.
Here is my entire reinstalls.sh script.
sudo rm /var/lib/libvirt/images/"$vpsName".qcow2 && sudo wget -O /var/lib/libvi$
guestfish -a /var/lib/libvirt/images/"$vpsName".qcow2 <<'EOF'
run
mount /dev/ubuntu-vg/root /
rm /etc/network/interfaces
EOF
sudo fusermount -u /mnt && virsh start "$vpsName" && echo "IT WORKED!"
I am open to any way of getting this to work, as long as its secure,
Thanks in advance,
Jake
EDIT:
If I run the script with a VPS name instead of a variable, it works. I just can't find a way to pass the variables from the website to the ubuntu16.04 OS.
Well one way would be to run each command from PHP:
shell_exec("sudo rm /var/lib/libvirt/images/" . $vpsName . ".qcow2");
shell_exec("sudo wget -O /var/lib/libvi ... etc");
The other would be to invoke your shell script from PHP, passing the vps name as a parameter:
shell_exec("reinstalls.sh " . $vpsName)
But then you'd have to rewrite the shell script to pick up the command line parameter and apply it as necessary. In the case of bash, this explains how to go about that.

Run sh file from php with cron

I have an sh file with file-removing commands.
I run it from php like this:
shell_exec("sudo -n ./truncatefiles.sh 2>&1");
Thats works fine if I open the PHP file from browser, but doesnt work from scheduled cron tab.
PHP user: www-data
If i run whoiami from cron, returns same: www-data
I added this to my visudo:
www-data ALL=(ALL) NOPASSWD: /www/sites/..../importscript/truncatefiles.sh
Shell exec for this sh file returns (from cron):
sudo: sorry, a password is required to run sudo
Why works it dirrefent way in cron?
What should I do for get it work?
PLease try to do the following,
Try to log your output from crotab to a file,
* * myscript.php >> /var/log/myjob.log 2>&1
This way you can debug your script.
1. Also the check the user and permissions for your shell script, php file.
2. try with sudo crotab -e

PHP exec not executing command

I have used php's exec to execute FFmpeg command but its not woking when I open it in browser. But when i run this php file script in terminal it works fine.And my php safe mode is off. please help me to get it solved. my php code is
<?php
$output=exec("ffmpeg -f image2 -i /home/phedra/imgs/image/img%03d.png -r 12 -s 610x489 /home/phedra/imgs/video/out.avi", $out);
echo $out;
echo $output;
?>
try giving full path where the ffmpeg application is located.
e.g.
/usr/bin/ffmpeg
So your function might look like:
$output=exec("/usr/bin/ffmpeg -f image2 -i /home/phedra/imgs/image/img%03d.png -r 12 -s 610x489 /home/phedra/imgs/video/out.avi", $out);
You must check what is the location of "ffmpeg".
I had this problem and it turned out it was Apache's permission on the public directory.
Note: I am running Ubuntu 14 on AWS
After installing FFmpeg I had to change the /var/www/* ownership to www-data.
sudo chown -R www-data:root /var/www
(the www-data is the important part here)
Then I had the following code running, and it works when I access it via URL (Apache)
// test.php
$run = system("/opt/ffmpeg/bin/ffmpeg -i /var/www/html/input.mp4 -vf scale=640:480 /var/www/html/output.mp4 &");
if($run) {
echo "success";
} else {
echo "failed";
}
The /opt/ffmpeg/bin/ffmpeg is where my FFmpeg is running from. Yours might be /usr/bin/ffmpeg or something else. You can locate it by typing locate ffmpeg in the command line and looking through the list it gives you.
The input file was a public .mp4 file and the output.mp4 file was going to the same location.
Run this in your command line: php test.php - works
Run this from your browser: yourwebsite.com/test.php - works
Note that if you are on windows you must use COMMAS. I.E:
$output=exec('"/usr/bin/ffmpeg" -f image2 -i /home/phedra/imgs/image/img%03d.png -r 12 -s 610x489 /home/phedra/imgs/video/out.avi', $out);
Like #Arfeen mentioned in his answer, you should execute the command with the path of ffmpeg, but, the given path in the answer "/usr/bin/ffmpeg" is not always the same.
First locate your ffmpeg by using the command :
which ffmpeg
The result in my case is :
/usr/local/bin/ffmpeg
Then go back to your php code and replace "ffmpeg" in the command by the path of ffmpeg (which is /usr/local/bin/ffmpeg in my case).

SSH Command From PHP not working. Command runs fine from command line

I inherited this intranet app which unzips some requested spooled reports and dumps them into a Samba folder users have access to. Here's the PHP:
$command = "$unzip_program $path_spooled/$zip_file $filename -d $target_dir";
$ssh_command = "$ssh_syscommand -i /web/live/sshkey_nopass reportuser#$archive_server \"$command\"";
$sshpipe2 = popen( $ssh_command, 'r' );
So if I echo the SSH command being run it's:
/usr/bin/ssh -i /web/live/sshkey reportuser#192.168.1.21 "/usr/bin/unzip -c /reports/spooled/2012/jan.zip 01SU7C.RPT" |
/usr/bin/ssh -i /web/live/sshkey reportuser#192.168.1.2 "cat > /reports/spooled/01SU7C.RPT"
(I inserted a carriage return after the pipe for readability)
If I execute that command from the command line it works fine. If run from php it fails with no errors.
All I need is some help working out where to look. I figure it could be a missing ssh key, but the server does show a login from that user when the command is executed.
What am I missing? Where should I look? Is there something about unzip I don't know about? Do I need to set some sort of context from Apache?

How to launch unoconv from php file

I want to launch the command "unoconv" from a script php.
$command = '/usr/bin/unoconv --server localhost --port 2002 --format=pdf file.rtf >/dev/null 2>/dev/null';
$rc = system( $command );
echo $rc;
The command return no result and the file is not created.
I think is a problem from access with www-data and unoconv.
When I'm launching the command in shell, the file is created.
Any idea?
You can add command unoconv to sudoers.
I do this in this way:
I create wrapper bash script in for example /usr/local/bin where I have command unoconv.
#!/bin/bash
if [ -z "$1" ]; then
echo "Must pass file";
exit 10;
fi
/usr/bin/unoconv -f pdf $1.rtf
after this I adding entry in /etc/sudoers.d:
www-data ALL=NOPASSWD: /usr/local/bin/unoconv.sh
And now you can call script in php:
exec('sudo /usr/local/bin/unoconv.sh '.$fileName);
Try to run
$output = `/usr/bin/unoconv --server localhost --port 2002 --format=pdf file.rtf`;
instead and see error messages.
For me works like this:
$cmd = "/usr/bin/unoconv -f docx files/thefile";
shell_exec($cmd);
of course you have to do this previously (if you lounch your php script from the web):
chown -R www-data:www-data files/
I have found a solution to this problem when running Apache. You have to create the home folder for the www-data user
sudo mkdir /home/www-data
sudo chown www-data /home/www-data
Lastly we will have to edit the home directory and default shell for the www-data user
sudo vim /etc/passwd
For the entry of www-data the last two strings have to be replaced respectively with
/home/www-data
/bin/bash
Simple as this
$output = shell_exec('/opt/libreoffice5.0/program/python unoconv -f rtf test.html');
Edit the path to suite your configuration.
It just works!
You may be running into an issue with LibreOffice, OpenOffice or soffice not being able to write to the current user's $HOME directory.
By running the command below I was able to identify the correct $HOME directory and see the error that was being generated.
$cmd = 'echo $HOME & unoconv -vvvv --format %s --output %s %s 2>/tmp/unoconv.debug.txt';
exec($cmd);
The verbose output of $cmd will be generated written to the file: /tmp/unoconv.debug.txt.
In my case the output was:
Verbosity set to level 5
DEBUG: Connection type: socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;StarOffice.ComponentContext
DEBUG: Existing listener not found.
DEBUG: Launching our own listener using /usr/lib64/libreoffice/program/soffice.bin.
Failed to connect to /usr/lib64/libreoffice/program/soffice.bin (pid=32012) in 6 seconds.
Connector : couldn't connect to socket (Success)
Error: Unable to connect or start own listener. Aborting.
The command ran seemed to fine as root, and as sudo -u nobody. On seeing this output I realized there was an issue with the home directory.
Kudos to Dag Wieers for his help - I'm hoping this helps other unoconv devs with their debugging.
