High Availability
We use "UCARP" software make sure PCC is always available.
How does UCARP work?

Configuration
Configuration File: /usr/local/pcc/ha_flip/flip_config
#!/bin/bash
MASTER=1 # set 1 if this server is master else set 0
MASTERIP="X.X.X.X"
SLAVEIP="Y.Y.Y.Y"
FLOATIP="Z.Z.Z.Z"
DEVICE="eth0"
IFACE="$DEVICE"
SECRET="secret"
keep_update(){
ip addr list | grep "$FLOATIP"
if [ $? == "0" ]
then
rsync -avzr –rsh=ssh /etc/asterisk/* root@$DSTIP:/etc/asterisk >> /var/log/ha_flip.log
rsync -avzr –rsh=ssh /var/spool/asterisk/* root@$DSTIP:/var/spool/asterisk >> /var/log/ha_flip.log
rsync -avzr –rsh=ssh /var/lib/asterisk/* root@$DSTIP:/var/lib/asterisk >> /var/log/ha_flip.log
rsync -avzr –rsh=ssh /var/www/* root@$DSTIP:/var/www >> /var/log/ha_flip.log
fi
}
MASTER: If it is master server, set it to 1; otherwise, change it to 0. MASTERIP: Set master server IP address SLAVEIP: Set slave server IP address FLOATIP: Set float IP address Device: The interface to use for sending advertise packets
Run script
You may run this command and add it to "/etc/rc.local":
/usr/local/pcc/ha_flip/flip_start_server
NOTE 1: Clients use Float IP to connect to server. NOTE 2: Since UCARP uses multicast packets to send advertise packets, it should not be filtered in network.
