MongoDB installation and master-slave replication

First, CentOS installation MongoDB

Opt directory, download MongoDB, unzip

#wget HTTPS://FASTDL.MONGODB.ORG/LINUX/MONGODB-LINUX-X86_64-3.0.6.TG

#tar-ZXVF mongodb-linux-x86_64-3.0.6.gz

Renaming mongodb-linux-x86_64-3.0.6 to MongoDB

#mv mongodb-linux-x86_64-3.0.6.gz MongoDB

Go to MongoDB New database folder, log folder, and Configuration folder

#cd mongodb#mkdir db#mkdir Log#mkdir conf

Under the MongoDB Directory command start:

Bin/mongod  --dbpath db--port 27000--logpath Log/mongod.log--fork True

(Personal habits Write these parameters to the configuration file) go to the Configuration folder, create a new profile mongod.conf, edit the content

Port = 27000 #数据库端口dbpath = db #数据库路径logpath = Log/mongod.log #日志输入fork = True #linux后台进程

New startup file startmongod.sh in MongoDB directory, writing content

Bin/mongod-f conf/mongod.conf

The MongoDB basic directory structure after configuration:

Start SH startmongod.sh

Second, MongoDB master-slave replication

Test environment: 192.168.199.199 master, 192.168.199.200 from, 192.168.199.201 from

In the installation configuration mongodb,mongod.conf the boot configuration contents are as follows

199

Port = 27000 #数据库端口dbpath = db #数据库路径logpath = Log/mongod.log #日志输入fork = True #linux后台进程master = #主数据库

200

Port = 27000 #数据库端口dbpath = db #数据库路径logpath = Log/mongod.log #日志输入fork = True #linux后台进程slave = #从数据库标识source = 192.168.1 99.199:27,000

201

Port = 27000 #数据库端口dbpath = db #数据库路径logpath = Log/mongod.log #日志输入fork = True #linux后台进程slave = #从数据库标识source = 192.168.1 99.199:27,000

！ (Three machine firewalls must open 27000 ports: iptables-i input-p TCP--dport 27000-j ACCEPT)

199 Main Library startup and log information

200 Startup and log information

199 Inserting data

200 Test Query synchronization data

201 The main library was not synchronized before, and now 201 synchronizes data as a new server database 199 Master Library

201 Log Display Synchronization

199 Main Library synchronization log information

Read and Write permissions are not opened from the database at this time

Which is the realization of read and write separation
