Unable to Install Mongo with ansible-examples

[rodrigovalin]

I keep getting this error:

Starting mongod: about to fork child process, waiting until server is ready for connections.

forked process: 3270 ERROR: child process failed, exited with error number 1

This is my hosts file:

#The site wide list of mongodb servers

# the mongo servers need a mongod_port variable set, and they must not conflict.
[mongo_servers]
ansible-mongo-00 mongod_port=2700
ansible-mongo-01 mongod_port=2701
ansible-mongo-02 mongod_port=2702
ansible-mongo-03 mongod_port=2703

#The list of servers where replication should happen, by default include all servers
[replication_servers]
ansible-mongo-00
ansible-mongo-01
ansible-mongo-02
ansible-mongo-03

#The list of mongodb configuration servers, make sure it is 1 or 3
[mongoc_servers]
ansible-mongo-00
ansible-mongo-01
ansible-mongo-02

#The list of servers where mongos servers would run. 
[mongos_servers]
ansible-mongo-00
ansible-mongo-01

The hosts are in my /etc/hosts file.

I added sudo to the site.yml file because if not, nothing gets installed:

---
# This Playbook would deploy the whole mongodb cluster with replication and sharding.

- hosts: all
  sudo: True
  roles:
  - role: common

- hosts: mongo_servers
  sudo: True
  roles:
  - role: mongod

- hosts: mongoc_servers
  sudo: True
  roles:
  - role: mongoc

- hosts: mongos_servers
  sudo: True
  roles:
  - role: mongos

- hosts: mongo_servers
  sudo: True
  tasks:
  - include: roles/mongod/tasks/shards.yml 

The ansible-mongo-{00-03} hosts are CentOS6.5 x64 (DigitalOcean images). I created a sudo user for this playbook to work and added the 'sudo' rules to the site.yml. The mongo servers refuse to start with the first error message.

I'm facing the same issue with Amazon Linux at AWS.

Have you tried installing Mongo with my fork? I have fixed several issues there.
