CENTOS7 MongoDB Shard Experiment Environment Construction (original)

 Construction of Mongodb3.3.6 CentOS7 Shard Experiment Environment first, topology diagram

ii. deployment of 1.Mongodb installation

3 servers are installed MongoDB, installation package to/usr/local/, in order to clear the display, each node created a MongoDB, altogether created 4, wherein, master, slave, arbiter build replica level.

2. Create a single shard replica level

1) Create log directory logs, data directory data/db, configuration directory in each directory conf

2) write the configuration file in each conf directory mongd.conf

192.168.1.82

Master:

port=10002

dbpath=/usr/local/mongodb-3.3.6_master/data/db

Logpath=/usr/local/mongodb-3.3.6_master/logs/mongod.log

Fork=true

Logappend=true

Nohttpinterface=true

Replset=test1 #副本集名称

Pidfilepath=/var/run/mongo_master.pid

bind_ip=192.168.1.82

Slave:

port=10001

dbpath=/usr/local/mongodb-3.3.6_slave/data/db

Logpath=/usr/local/mongodb-3.3.6_slave/logs/mongod.log

Fork=true

Logappend=true

Nohttpinterface=true

Replset=test1

Pidfilepath=/var/run/mongo_slave.pid

bind_ip=192.168.1.82

Arbiter:

port=10000

dbpath=/usr/local/mongodb-3.3.6_arbiter/data/db

Logpath=/usr/local/mongodb-3.3.6_arbiter/logs/mongod.log

Fork=true

Logappend=true

Replset=test1

Nohttpinterface=true

Pidfilepath=/var/run/mongo_arbiter.pid

bind_ip=192.168.1.82

3) Start MongoDB separately

/usr/local/mongodb-3.3.6_master/bin/mongod-f. /conf/mongod.conf

/usr/local/mongodb-3.3.6_slave/bin/mongod-f. /conf/mongod.conf

/usr/local/mongodb-3.3.6_arbiter/bin/mongod-f. /conf/mongod.conf

4) Configure the replica level

Enter Master's MONGO shell

#cd/usrl/local/mongodb-3.3.6_master/bin

#./mongo192.168.1.82:10002

Switch to Admin library

>useadmin
