Can you share the command line of master & slave? According the following information,
it seems master run without "--zk" option.

I installed using yum -y install mesos. That did work.   
Now the master and slaves do not see each other.

Here is the master:
$ ps -ef | grep mesos | grep -v grepstack    30236 17902  0 00:09 pts/4    00:00:04 /mnt/mesos/build/src/.libs/lt-mesos-master
--work_dir=/tmp/mesos --ip=10.xx.xx.124

Here is one of the 20 slaves:
 ps -ef | grep mesos | grep -v greproot     26086     1  0 00:10 ?        00:00:00 /usr/sbin/mesos-slave
--master=zk://10.xx.xx.124:2181/mesos --log_dir=/var/log/mesosroot     26092 26086  0 00:10
?        00:00:00 logger -p user.info -t mesos-slave[26086]root     26093 26086  0 00:10 ?
       00:00:00 logger -p user.err -t mesos-slave[26086]

Note the slave and master are on correct same ip address
The /etc/mesos/zk seems to be set properly : and I do see the /mesos node in zookeeper is
updated after restarting the master
However the zookeeper node is empty:
[zk: localhost:2181(CONNECTED) 10] ls /mesos[]
The node is world accessible so no permission issue:
[zk: localhost:2181(CONNECTED) 12] getAcl /mesos
'world,'anyone: cdrwa
Why is the zookeeper node empty?  Is this the reason the  master and slaves are not connecting?

No problem, they have a "downloads" link inn their menu: https://mesosphere.com/downloads/

@Craig . That is an incomplete answer - given that such links are not presented in an obvious
manner .  Maybe you managed to find  a link on their site that provides prebuilt for Centos7:
if so then please share it.   
I had previously found a link on their site for prebuilt binaries but is based on using CDH4
(which is not possible for my company). It is also old.

Mesosphere has packages prebuilt, go to their site to find how to install

After following the directions here:   http://mesos.apache.org/gettingstarted/
Which for centos7 includes the following:



  # Change working directory.
    $ cd mesos

    # Bootstrap (Only required if building from git repository).
    $ ./bootstrap

    # Configure and build.
    $ mkdir build
    $ cd build
    $ ../configure
    $ make
In order to speed up the build and reduce verbosity of the logs, you can append-j <number
of cores> V=0 to make.    # Run test suite.
    $ make check

    # Install (Optional).
    $ make install

But the installation is not correct afterwards: here is the bin directory:

So .. two things:
(a) what is missing from the installation instructions?
(b) Is there an up to date rpm/yum installation for centos7?
