"MongoDB Learning Note 31" MongoDB Configuration Replica set

First, configure the environment

1. Two CentOS server with MongoDB installed; (Installation reference http://281816327.blog.51cto.com/907015/1598270)

2. The IP of two servers is 192.168.1.112, 192.168.1.113 respectively;

3. Two server firewalls let go of the default 27017 port of MongoDB;

Second, configure the server

Both servers do the following configuration

Create a/data/db folder

Mkdir/date && mkdir/data/db

Modifying a configuration file

Vim/etc/mongodb.conf

Some of the important parameters are modified as follows:

#where to log logpath=/var/log/mongodb/mongod.loglogappend=true# fork and run in background fork=truedbpath=/data/db# Location of Pidfile pidfilepath=/var/run/mongodb/mongod.pid# Listen to local interface only.   Comment out to listen on all interfaces.   #bind_ip =127.0.0.1# Enable The HTTP interface (Defaults to Port 28017). httpinterface=true# in replicated MONGO databases, specify the replica set name here Replset=spock

Start MongoDB:

Mongod–f/etc/mongodb.conf–-rest

Third, configure the replica set

Enter MongoDB's shell on 192.168.1.122, test the connection 192.168.1.113 and create a config document:

[[email protected] ~]# mongo   mongodb shell version: 2.6.6     connecting to: test    > db= (New Mongo (" 192.168.1.113:27017 ")). Getdb (" test ")     test    > config={" _id ":" Spock ",    ... " members ": [    ... {" _id ": 0," host ":" 192.168.1.112:27017 "},    ... {" _id ": 1," host ":" 192.168.1.113:27017 "}]}     {             "_id"  :  "Spock" ,             "Members"  : [                     {                               "_id"  : 0,                              " Host " : " 192.168.1.112:27017 "                     },                     {                               "_id"  : 1,                              "Host"  :   "192.168.1.113:27017"                      }            ]     }

Initialize replica set:

> rs.initiate (config) {"info": "Config now saved locally. Should come online in about a minute. "," OK ": 1}

Iv. Verification Results

Enter the MongoDB shell on the 192.168.1.112:

[[email protected] ~]# MONGO MongoDB shell version:2.6.6 connecting To:test spock:secondary>

Enter the MongoDB shell on the 192.168.1.112:

[[email protected] ~]# MONGO MongoDB shell version:2.6.7 connecting To:test spock:primary>

You can see the spock:secondary and Spock:primary keywords, indicating that the replica set configuration is complete;
