How to install Replica Sets for MongoDB learning and sorting

Preparation:
Server Port Data Directory log replica set key file
Server1 28010/app/mongo/mongodb/data/sets/r0/app/mongo/mongodb/data/sets/log/r0.log/app/mongo/mongodb/data/sets/key /r0
Server2 28011/app/mongo/mongodb/data/sets/r1/app/mongo/mongodb/data/sets/log/r2.log/app/mongo/mongodb/data/sets/key /r1
Server3 28012/app/mongo/mongodb/data/sets/r2/app/mongo/mongodb/data/sets/log/r3.log/app/mongo/mongodb/data/sets/key /r2

1. Create data files, Log Path directories, and replica set key files
Mkdir-p/app/mongo/mongodb/data/sets/r0
Mkdir-p/app/mongo/mongodb/data/sets/r1
Mkdir-p/app/mongo/mongodb/data/sets/r2
Mkdir-p/app/mongo/mongodb/data/sets/key/
Mkdir-p/app/mongo/mongodb/data/sets/log/

Echo "test sets">/app/mongo/mongodb/data/sets/key/r0
Echo "test sets">/app/mongo/mongodb/data/sets/key/r1
Echo "test sets">/app/mongo/mongodb/data/sets/key/r2

Chmod 600/app/mongo/mongodb/data/sets/key/r *

2. Start three mongodb instances to simulate three node servers:

/App/mongo/mongodb/bin/mongod -- replSet rs1 -- keyFile/app/mongo/mongodb/data/sets/key/r0 -- port 28010 -- dbpath =/app/mongo/ mongodb/data/sets/r0 -- logpath =/app/mongo/mongodb/data/sets/log/r0.log -- logappend -- fork

/App/mongo/mongodb/bin/mongod -- replSet rs1 -- keyFile/app/mongo/mongodb/data/sets/key/r1 -- port 28011 -- dbpath =/app/mongo/ mongodb/data/sets/r1 -- logpath =/app/mongo/mongodb/data/sets/log/r2.log -- logappend -- fork

/App/mongo/mongodb/bin/mongod -- replSet rs1 -- keyFile/app/mongo/mongodb/data/sets/key/r2 -- port 28012 -- dbpath =/app/mongo/ mongodb/data/sets/r2 -- logpath =/app/mongo/mongodb/data/sets/log/r3.log -- logappend -- fork

3. initialize the Replica Sets Environment
[Mongodb @ www.bkjia.com mongo] $/app/mongo/mongodb/bin/mongo-port 28010 // connection

> Config_rs = {_ id: 'rs1', members: [{_ id: 0, host: 'localhost: 100'}, {_ id: 1, host: 'localhost: 28011 '}, {_ id: 2, host: 'localhost: 28012'}]}
> Rs. initiate (config_rs );

4. view the status of the replica set and analyze the running indicators of the replica set ,:

OK.
