MongoDB主从复制实验 master/slave

MongoDB部署实验系列文章,MongoDB做为NoSQL数据库,最近几年持续升温,越来越多的企业都开始尝试用MongoDB代替原有Database做一些事情。MongoDB也在集群,分片,复制上也有相当不错的的表现。我通过将做各种MongoDB的部署实验进行介绍。

第一篇 MongoDB主从复制实验 master/slave,分为5个部分

  1. 初始化文件目录
  2. 启动master
  3. 启动slave
  4. 向master插入数据测试
  5. 在slave中查询数据

系统环境介绍:

Ubuntu 12.04. LTS 64bit Server

简单安装MongoDB

在source.list文件中,增加10gen的源

~ vi /etc/apt/source.list
deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen
~ sudo apt-get update
~ sudo apt-get install mongodb-10gen

初始化文件目录(MongoDB存储)

~ pwd
/home/conan/dbs

~ mkdir master slave
~ ls -l
drwxrwxr-x 2 conan conan 4096 May 31 13:54 master/
drwxrwxr-x 2 conan conan 4096 May 31 14:04 slave/

启动master

~ mongod --dbpath /home/conan/dbs/master --port 10000 --master --rest --nojournal --fork --logpath /home/conan/dbs/master.log
about to fork child process, waiting until server is ready for connections.
forked process: 4827
all output going to: /home/conan/dbs/master.log
child process started successfully, parent exiting

启动slave

~ mongod --dbpath /home/conan/dbs/slave --port 10001 --slave --source localhost:10000 --rest --nojournal --fork --logpath /home/conan/dbs/slave.log
about to fork child process, waiting until server is ready for connections.
forked process: 5062
all output going to: /home/conan/dbs/slave.log
child process started successfully, parent exiting

向master插入数据测试

~ mongo localhost:10000
MongoDB shell version: 2.4.3
connecting to: localhost:10000/test
> db.master.insert({uid:1000})
> db.master.find()
{ "_id" : ObjectId("51a83e979d113ea810e6ddbd"), "uid" : 1000 }

在slave中查询数据

~ mongo localhost:10001
MongoDB shell version: 2.4.3
connecting to: localhost:10001/test
> db.master.find()
{ "_id" : ObjectId("51a83e979d113ea810e6ddbd"), "uid" : 1000 }

 

在slave中,我们找了到数据,是从master同步过来的。实验完成!

主从实验是MongoDB最简单的部署实验了。
