Libreoffice source not found aws linux

Question

I am trying to convert a files from doc to pdf on my aws linux server. On my previous machine it worked fine but now i am having issues on my new machine. The only difference is i have upgraded from PHP 7.0 to PHP 7.2. and libre office version

LibreOffice 6.0.1.1 00m0(Build:1)

I have tried giving root permissions to libreoffice and the package that executes the command but no success.

This is the package i am using https://github.com/szonov/libreoffice-converter

I am using it with laravel 5.4. This is the code in the package that performs the action

    $replacement = array(
        'bin'        => $this->bin,
        'convert_to' => $convert_to,
        'outdir'     => $outdir,
        'source'     => $this->source
    );
    $cmd = $this->makeCommand($replacement);
    $cmd = "sudo ".$cmd;
    shell_exec($cmd);
    $result = false;
    if (file_exists($outfile)) {
        $this->mkdir(dirname($this->destination));
        $result = rename($outfile, $this->destination);
    }

    // remove temporary sub directory
    rmdir($outdir);
    return $result;

I have tried appending sudo since when i dd the command and execute is using sudo it worked in command line..

Answer 1

So you need to either use something like below

Execute root commands via PHP

Or you should enable to login to the www-data user

sudo usermod -s /bin/bash www-data

Then you should login with that user and fix all the issues with permissions so you can run the command

sudo su www-data

Once you have done this make sure to reset the login using below

sudo usermod -s /bin/nologin www-data

Once the issue is sorted out in user terminal, you can run the commands without issue in apache as well
