MongoDB Master-Slave cluster configuration detailed

Create the necessary directories and authentication files:

[Root@mongo mongo]# mkdir keyfile

[Root@mongo mongo]# echo "MONGO cluster One" > KEYFILE/M1

[Root@mongo mongo]# echo "MONGO cluster One" > keyfile/m2

[Root@mongo mongo]# echo "MONGO cluster One" > keyfile/m3

Start services on different ports

Mongod--replset MCO--keyfile/usr/local/mongo/keyfile/m1--fork--port- Logpath=/usr/local/mongo/log/m1.log--logappend

Mongod--replset MCO--keyfile/usr/local/mongo/keyfile/m2--fork--port- Logpath=/usr/local/mongo/log/m2.log--logappend

Mongod--replset MCO--keyfile/usr/local/mongo/keyfile/m3--fork--port- Logpath=/usr/local/mongo/log/m3.log--logappend

Mongod--replset MCO--keyfile/usr/local/mongo/keyfile/m4--fork--port- Logpath=/usr/local/mongo/log/m4.log--logappend

Mongod--replset MCO--keyfile/usr/local/mongo/keyfile/m5--fork--port- Logpath=/usr/local/mongo/log/m5.log--logappend--fastsync
