Problem changing default data_directory in PG 9.6 + CentOS6

I have an env running a changed data_directory fine in a devel
    machine PG 9.4 using Fedora23.
    Now, I have a server machine with CentOS where I downloaded the RPMs
    from repo <a rel="nofollow" target="_blank"
href="https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-centos96-9.6-3.noarch.rpm"
      class="ot-anchor aaTEdf" jslog="10929; track:click"
dir="ltr">https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-centos96-9.6-3.noarch.rpm.
    All the configs run fine if I doesn't change the default
    data_directory. But I need to use the path /sistemas/sat4/bdpg.

    I did these commands:

    mkdir /sistemas/sat4/bdpg
    chown postgres /sistemas/sat4/bdpg
    chmod 700 /sistemas/sat4/bdpg
    su - postgres
    /usr/pgsql-9.6/bin/initdb -D /sistemas/sat4/bdpg
    exit

    Then, I changed data_directory to /sistemas/sat4/bdpg and tried to
    restart PG:
    service postgresql-9.6 restart
    STOP => OK
    START => FAILED

    I disabled se_linux.
    The file /var/lib/pgsql/9.6/pgstartup.log just said to see future
    output in pg_log.
    The file data/pg_log/postgresql-Mon.log doesn't say anything about
    errors.

    The strange is that startup arises a FAILED message, but the process
    "/usr/pgsql-9.6/bin/postmaster -D /var/lib/pgsql/9.6/data" is
    running (and the children logger/checkpointer/etc). But I don't get
    to connect using pgAdmin3. Then, I have to kill manually postmaster
    (because service script doesn't understand postmaster.pid in the new
    data dir), comment data_directory to use default place, start and
    connect to pgAdmin3. Then, start/stop/start/etc run fine lookup for
    postmaster.pid in /var/lib/pgsql/9.6/data.
