[SOLVED] ansible hangs in "sudo yum install"' step

Issue

I am trying to setup ansible (2.0) for installing software on a linux box

ies-iesd-jktools is the machine with ansible. ies-iesd-git-06 is the target. User account is iesdgrid that can do sudo on target machine.

Following command hangs on remote:-

    ies-iesd-jktools:~/ansible$ ansible ies-iesd-git-06  \
           -i inventory  -m raw \
           -a "sudo yum install -y python-simplejson"   -vvvv

Using /usr/src/ansible/ansible.cfg as config file

SUDO password: <I type password here>

Loaded callback minimal of type stdout, v2.0
<ies-iesd-git-06> ESTABLISH CONNECTION FOR USER: None on PORT 22 TO ies-iesd-git-06
<ies-iesd-git-06> EXEC sudo yum install -y python-simplejson

This starts a sudo on target machine, but does not proceed as if it is waiting for password

$ hostname
ies-iesd-git-06
$
$ ps -ef| grep su
root       583   582  0 09:01 pts/1    00:00:00 sudo yum install -y python-simplejson
iesdgrid   811   771  0 09:05 pts/2    00:00:00 grep su

What is the mistake?

After a while I got

sudo: pam_authenticate: Conversation error

(manually login to the target machine and sudo there works. )

Solution

You need to specify the --become --become-user root --ask-become-pass parameters so ansible will sudo su to root prior to executing the command.

ansible -m raw -a "yum install python-simplejson" testserver --ask-become-pass --become-user root --become
SUDO password:
testserver | SUCCESS | rc=0 >>
