CentOS 7.0 MongoDB Database Master-Slave synchronous installation configuration steps

Operating System: CentOS 7.0 64-bit

MongoDB database version:mongodb-linux-x86_64-2.6.5

preparatory work: MongoDB Database Installation

Specific actions:

First, configure the MongoDB main Library

The following actions are performed on the MongoDB main library server

1, cd/usr/local/mongodb/#进入MongoDB安装目录

Vi/usr/local/mongodb/mongodb.conf #编辑, add the following code on the last line of the original configuration file

Master=true #设置为主库

oplogsize=2048 #同步复制的日志大小设置, per MB

: wq! #保存退出

After adding it, the following figure shows:

2, restart the MongoDB database

Service Mongod Stop #停止MongoDB

Service Mongod Start #启动MongoDB

Second, configure MongoDB from the library

The following actions are performed on the MongoDB from the library server

1, cd/usr/local/mongodb/#进入MongoDB安装目录

Vi/usr/local/mongodb/mongodb.conf #编辑, add the following code on the last line of the original configuration file

Slave=true #设置为从库

source=192.168.21.100:27017 #设置要同步的MongoDB主库IP地址和端口, format: IP: Port

slavedelay=10 #设置从库同步主库的延迟时间, unit seconds

Autoresync=true #主从数据不一致时, automatic resynchronization

: wq! #保存退出

After adding it, the following figure shows:

2, restart the MongoDB database

Service Mongod Stop #停止MongoDB

Service Mongod Start #启动MongoDB

Third, test MongoDB master and slave synchronization

1, in the main library to operate

MONGO #进入MongoDB控制台

Use test #创建数据库test Note that if nothing is done, the library will be deleted by the system .

Db.createcollection ("test_table") #创建表test_table

Show Collections #查看

Db.test_table.insert ({uid:1,name: "System Operation Dimension", URL: "http://www.osyunwi.com", Content: "System Operation Dimension Official website"}) #插入数据到表osyunweidb_ Table in

Db.osyunweidb.find ();

Show DBS #如下图所示, you can see that the test database has been created

Exit #退出

2, the operation from the library

MONGO #进入MongoDB控制台

Show DBS #如下图所示, you can see that the test database is already available from the library , master-slave sync has run successfully

Exit #退出

At this point, Linux under the MongoDB database master-Slave synchronization configuration completed.
