I was able to get a single node environment setup on Ubuntu 14.04.1 following this guide: http://mesosphere.io/learn/install_ubuntu_debian/
The single slave registered with the master via the local Zookeeper and I could run basic commands by posting to Marathon. I then tried to build a multi node cluster following this guide: http://mesosphere.io/docs/mesosphere/getting-started/cloud-install/ The guide walks you through using the Mesosphere packages to install Mesos, Marathon, and Zookeeper one one node that will be the master and on the slave just Mesos. You then disable automatic start of: mesos-slave on the master, mesos-master on the slave, and zookeeper on the slave. It ends up looking like: NODE 1 (MASTER): - IP Address: 10.1.100.116 - mesos-master - marathon - zookeeper NODE 2 (SLAVE): - IP Address: 10.1.100.117 - mesos-slave The issue I’m running into is that the slave rarely is able to register with the master using the Zookeeper. I can never run any jobs from marathon (just trying a simple sleep 5 command). Even when the slave does register the Mesos UI shows 1 “Deactivated” slave — it never goes active. Here are the values I have for /etc/mesos/zk: MASTER: zk://10.1.100.116:2181/mesos SLAVE: zk://10.1.100.116:2181/mesos Any ideas of what to troubleshoot? Would greatly appreciate pointers. Environment details: - Ubuntu Server 14.04.1 running as VMs on ESXi 5.5U1 - Mesos: 0.20.0 - Marathon 0.6.1 There are no apparent connectivity issues, and I’m not having any problems with other VMs on the ESXi host. All VM to VM communication is on the same VLAN and within the same host.
