SHARDED MONGODB CLUSTER
=======================

Run every script below from the extension's top-level directory.

On the router/orchestration computer, create and edit the active setup file:

    cp _mongodb_cluster_setup.bash.in _mongodb_cluster_setup.bash

Set the router hostname, config-server hostname and the shard-host array.
Check out the same extension and run ./INSTALL.sh on every configured host,
then copy the same active setup file to each checkout.

From the router computer:

    source ./SETUP.bash
    ./CLUSTER-SERVER/COPY-MONGODB-CLUSTER-SETUP.sh
    ./CLUSTER-SERVER/CHECK-MONGODB-CLUSTER-SETUP.sh
    ./CLUSTER-SERVER/CONFIGURE-MONGODB-CLUSTER.sh

Normal cluster-wide operation from the router computer:

    ./CLUSTER-SERVER/RUN-MONGODB-CLUSTER-START.sh
    ./CLUSTER-SERVER/RUN-MONGODB-CLUSTER-STATUS.sh
    ./CLUSTER-SERVER/RUN-MONGOSH.sh
    ./CLUSTER-SERVER/RUN-MONGODB-CLUSTER-STOP.sh

Role-specific and local-process scripts are provided for diagnosis and manual
operation. CONFIGURE scripts are normally needed only during initial setup or
when a new shard is introduced.
