How to get real time output from ansible-playbook process when called in PHP?

[Sally Paner]

I have a simple PHP script that runs ansible-playbook and polls the output.  It seems that ansible runs to completion before it displays the output.

This is my simple code:

(process.php)

$handle = popen("ansible-playbook set-mysqld-max-connection-with-template.yml", "r");

while(!feof($handle)) {

$buffer = fgets($handle);

      echo $buffer . "\n";

   usleep(100000); //sleep for 0.1 seconds

}

pclose($handle);

Output:

PLAY [web] ********************************************************************

GATHERING FACTS ***************************************************************

ok: [selenium1.example.com]

TASK: [set-mysqld-max-connection-with-template | set mysqld (my.cnf) max_connection with template] ***

ok: [selenium1.example.com]

PLAY RECAP ********************************************************************

selenium1.example.com       : ok=2    changed=0    unreachable=0    failed=0

Hi Brian;


Thanks for the reply.  I am just wondering that if I run ansible-playbook directly on the command line, it gives me real-time output, but if called from PHP it seems that ansible-playbook waits to finish the playbook before it returns any output.

you are probably buffering the output in php

Hi Brian;

I've resolved my problem by installing ansible through git because it pulls the latest version of ansible.  My previous ansible was installed through yum.  Thanks.
