require 'recipe/laravel.php';

// Project name
set('application', REMOVED);
set('default_stage', 'staging');


// Project repository
set('repository', REMOVED);

// [Optional] Allocate tty for git clone. Default value is false.
set('git_tty', true); 

// Shared files/dirs between deploys 
add('shared_files', []);
add('shared_dirs', []);

// Writable dirs by web server 
add('writable_dirs', []);


// Hosts

host('production')
    ->hostname(REMOVED)
    ->port(25560)
    ->set('deploy_path', '/var/www/{{application}}');

host('staging')
    ->hostname(REMOVED)
    ->port(25560)
    ->set('deploy_path', '/var/www/staging_{{application}}');

// Tasks

task('build', function () {
    run('cd {{release_path}} && build');

Check what your local system has ssh installed.

[danielpclin]

My ssh is installed in C:\Windows\System32\OpenSSH\ssh.exe
Version is OpenSSH_for_Windows_7.6p1, LibreSSL 2.6.4

[staabm]

Is the ssh command with $PATH ?

[danielpclin]

yes it is in PATH, and i can directly call ssh in terminal anywhere

[staabm]

It seems its not accessible to your php cli

[danielpclin]

What can i do to test it?

[staabm]

Maybe php -r 'echo exec("ssh -v");' from your cli

Just guessing..

[danielpclin]

There is no output

[staabm]

Missed a echo, just added it above

[danielpclin]

PHP Parse error:  syntax error, unexpected ''echo' (T_ENCAPSED_AND_WHITESPACE), expecting end of file in Command line code on line 1

[staabm]

Semicolon on the wrong place... another edit above

[danielpclin]

Still not working. I tried php -a to get into interactive mode and ran echo exec("ssh -v");, it confirms that php can't access ssh. 'ssh' is not recognized as an internal or external command, operable program or batch file. Is there a way to let php access ssh

[staabm]

Usually just set the $PATH variable correctly

[danielpclin]

I’m quite sure that my $PATH is set correctly

[antonmedv]

Check user/group on ssh bin.

[antonmedv]

Can user you are running from.

[danielpclin]

I'm running on windows. Windows doesn't have the user/group permission problem

[antonmedv]

Try windows subsystem for ubuntu

[danielpclin]

The main problem is that php can't ssh while I can in command prompt. I also tried other commands like git in php and it works flawlessly. Not sure what it is all about.

[antonmedv]

Can't tell too. I need your machine to investigate :)

[danielpclin]

I did some more investigation, it seems that in php, it doesn't see some directories. like OpenSSH in WindowsSystem32. Very Weird.....

[danielpclin]

I think this may be a issue with php and Windows 10. Closing the issue.

[danielpclin]

The reason that ssh can't be called is because XAMPP uses 32bit version of php, and exec in 32bit php uses cmd in C:\Windows\SysWOW64 which somehow doesn't have ssh. The solution is to use 64 bit php.

@danielpclin Just thought you should know, this comment really helped me out. Thank you.
