  • If you're using RHEL5,6 or derivatives then you must install EPEL support first.

  • Build erlrtpproxy, erlang-rtplib and erlrtpproxy-ser RPMs. Also you might be interested in erlrtpproxy-radius RPM as well, but that's optional. You may download SRPM packages here. Prebuilt RPMs are also available.

  • Install erlrtpproxy (it will create erlrtpproxy user during installation) and erlang-rtplib via yum on each machine in your cluster

  • Raise max number of open files in /etc/security/limits.conf.

  • Edit /var/lib/erlrtpproxy/.hosts.erlang. It should contain something like this:

    '192.168.100.1'.
    '192.168.100.2'.

  • Edit /var/lib/erlrtpproxy/.erlang.cookie (it must exist on every host available in cluster and must contain the same value). No newlines are allowed (note -n switch):

    echo -n `echo -n "yourpassphrase" | md5sum | cut -d " " -f 1 ` > /var/lib/erlrtpproxy/.erlang.cookie
    chmod 600 /var/lib/erlrtpproxy/.erlang.cookie
    chown erlrtpproxy:erlrtpproxy /var/lib/erlrtpproxy/.erlang.cookie

  • Install OpenSSH public keys from main machine on every node. user erlrtpproxy from main node must be able to log in w/o password on every other note - ensure that trying to login manually. Note that w/o manually login first Erlang will refuse to login because of unknown host's fingerprint.

  • Edit /etc/sysconfig/erlrtpproxy config. At least you will need to adjust ERL_NODE value.

  • Edit /etc/erlrtpproxy.config. You'll need to adjust syslog's address (only UDP is supported for now) and rtpproxy_radius settings (if you decide to use it).

  • Install erlrtpproxy-ser on main node only (where your rtpproxy is running) and change /etc/sysconfig/ser according to your own setup. At least you will need to adjust ERL_NODE value.

  • Edit /etc/ser.config. You need at least to provide address to listen for OpenSER/OpenSIPs/Kamailio commands at.

  • Start erlprtpproxy first as any other system daemon by typing: /etc/init.d/erlrtpproxy start

  • Start erlprtpproxy-ser controlling module as any other system daemon by typing: /etc/init.d/ser start

  • Take a look at syslog's output ( /var/log/messages ) for details.
