Hi Pradeep, My steps was pretty simple just as https://github.com/apache/mesos/blob/master/docs/getting-started.md#examples
On Master node: root@mesos1:~/src/mesos/m1/mesos/build# GLOG_v=1 ./bin/mesos-master.sh --ip=192.168.0.107 --work_dir=/var/lib/mesos On 3 Slave node: root@mesos007:~/src/mesos/m1/mesos/build# GLOG_v=1 ./bin/mesos-slave.sh --master=192.168.0.107:5050 Then schedule a task on any of the node, here I was using slave node mesos007, you can see that the two tasks was launched on different host. root@mesos007:~/src/mesos/m1/mesos/build# ./src/mesos-execute --master= 192.168.0.107:5050 --name="cluster-test" --command="/bin/sleep 100" --resources="cpus(*):1;mem(*):256" I1005 16:49:11.013432 2971 sched.cpp:164] Version: 0.26.0 I1005 16:49:11.027802 2992 sched.cpp:262] New master detected at [email protected]:5050 I1005 16:49:11.029579 2992 sched.cpp:272] No credentials provided.
