Mesosphere: Webserver on port 5050 not responding / Failed to create Zookeeper, zookeeper_init: No such file or directory

Question

I have followed the instructions over at digital oceans on how to setup mesosphere on Ubuntu 14.04. Everything went fine up to the chapter "Configure Service Init Rules and Restart Services".

The issue is that on port 5050 no website is displayed (connection refused) when accessed via the public IP as well as from localhost, iptables is empty.

My setup running on VMware Workstation are 3 mesos-masters and 7 mesos-slaves, each of them running Ubuntu 14.04 server. Installation and configuration was done with clusterssh to ensure all VMs are set-up equally.

root@host01:~# uname -a
Linux host01 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Mesos-Master is running

root@host01:~# service mesos-master status
mesos-master start/running, process 15445

Mesos-Master is listening on port 5050

In /var/log/mesos/mesos-master.ERROR it says:

F0514 10:35:04.625597 10451 zookeeper.cpp:132] Failed to create Zookeeper, zookeeper_init: No such file or directory

Being new to mesos and zookeeper I don't know how to resolve this issue and would kindly ask for your help.

Thanks.

Please verify the below path: - /etc/zookeeper/conf/zoo.cfg - /etc/zookeeper/conf/myid - /etc/mesos-master/quorum - /var/lib/zookeeper/myid

Make sure zoo.cfg contains all the server list with same value as in myid file for each node. One more thing, delete all the backup file if exist at that location and disable the firewall.
