# 15.1. Short Version

The following short installation allows to install a simple cluster on a local machine with 1 Coordinator, 2 Datanodes and 1 GTM. When installing a more complex cluster, you might change the number of Coordinators and Datanodes, and might have to start nodes on different servers.

    ./configure
    gmake
    su
    gmake install
    adduser postgres
    mkdir /usr/local/pgsql/data_coord1
    mkdir /usr/local/pgsql/data_datanode1
    mkdir /usr/local/pgsql/data_datanode2
    mkdir /usr/local/pgsql/data_gtm
    chown postgres /usr/local/pgsql/data_coord1
    chown postgres /usr/local/pgsql/data_datanode1
    chown postgres /usr/local/pgsql/data_datanode2
    chown postgres /usr/local/pgsql/data_gtm
    su - postgres
    /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data_coord1 --nodename coord1
    /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data_datanode1 --nodename datanode1
    /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data_datanode2 --nodename datanode2
    /usr/local/pgsql/bin/initgtm -D /usr/local/pgsql/data_gtm -Z gtm

    /usr/local/pgsql/bin/psql -c "SELECT pgxc_pool_reload()" postgres

    /usr/local/pgsql/bin/psql test

The long version is the rest of this chapter.
