Redis Cluster Setup Complete Cross Server Clustering with Slotting

Full Redis Cluster setting up process

Make all nodes up
======================

[prepaid@GSI-1 cluster]$ ../../src/redis-server redis30011.conf


../../src/redis-server redis8580.conf
../../src/redis-server redis8581.conf
../../src/redis-server redis8582.conf
../../src/redis-server redis8583.conf

Make cluster nodes meet each other
=====================================
with respect to one  node link other nodes as below

./redis-cli -c -p 8580 cluster meet 10.5.73.62 8581
./redis-cli -c -p 8580 cluster meet 10.5.73.62 8582
./redis-cli -c -p 8580 cluster meet 10.5.73.62 8583
./redis-cli -c -p 8580 cluster meet 10.5.73.63 8580
./redis-cli -c -p 8580 cluster meet 10.5.73.63 8581
./redis-cli -c -p 8580 cluster meet 10.5.73.63 8582
./redis-cli -c -p 8580 cluster meet 10.5.73.63 8583



Assign Slots to Master Nodes
==================================

for slot in {0..4095}; do ./redis-cli -p 8580 CLUSTER ADDSLOTS $slot > /dev/null; done;
for slot in {4096..8191}; do ./redis-cli -p 8581 CLUSTER ADDSLOTS $slot > /dev/null; done;
for slot in {8192..12287}; do ./redis-cli -h 10.5.73.63 -p 8580 CLUSTER ADDSLOTS $slot > /dev/null; done;
for slot in {12288..16383}; do ./redis-cli -h 10.5.73.63 -p 8581 CLUSTER ADDSLOTS $slot > /dev/null; done;


===to check info
./redis-cli -p 8580 CLUSTER info  ( If slots are not assigned it will be fail, if slots assigned then it should come as OK)



=====for Deleting slots
for slot in {0..4095}; do ./redis-cli -p 8580 CLUSTER DELSLOTS $slot > /dev/null; done;


========== for Checking NODES 
./redis-cli -p 8580 CLUSTER NODES


Assign Slaves to Masters( maps the slave and master with respect to slave port and master Key)
=================================
