This article shows you how to achieve MongoDB database master-slave replication, the content is concise and easy to understand, absolutely can make your eyes bright, through the detailed introduction of this article, I hope you can get something.

[root@localhost ~] # mkdir / data/db/master

[root@localhost ~] # mkdir / data/db/slave

Master: just take the-master parameter to show that it is a master, which is quite convenient.

[root@localhost] # / usr/local/bin/mongod-- master

-dbpath=/data/db/master-port=11536 &

[1] 10939

[root@localhost ~] # Mon

Jul 25 20:21:59 [initandlisten] MongoDB

Starting: pid=10939 port=11536 dbpath=/data/db/master

Master=1 32-bit

From: with-- slave parameter indicates that it is a slave, specify-- source, the address and port of the master, which is much more convenient than MYSQL.

[root@localhost bin] # / usr/local/bin/mongod-port

11537-slave-dbpath=/data/db/slave-source 127.0.0.1 source 11536

Mon Jul 25 20:25:52 [initandlisten] MongoDB

Starting: pid=11158 port=11537 dbpath=/data/db/slave

Slave=1 32-bit

Open a new terminal, log in to 11536 (master), and write a record

[root@localhost] # / usr/local/bin/mongo-- port=11536

MongoDB shell version: 1.8.2

Connecting to: 127.0.0.1:11536/test

> use brucezuo

Switched to db brucezuo

> db.createCollection ("table1")

{"ok": 1}

> db.table1.insert ({id:1,name: "zxy", age:29})

>

Open a new terminal, log in to 11537 (from), and check whether the data is consistent.

[root@localhost] # / usr/local/bin/mongo-- port=11537

MongoDB shell version: 1.8.2

Connecting to: 127.0.0.1:11537/test

> use brucezuo

Switched to db brucezuo

> db.table1.find ()

{"_ id": ObjectId ("4e2e348ed502dbae1aee469e"), "id": 1, "name": "zxy", "age": 29}
