MONGO Installation Deployment

MongoDB Download Address: https://www.mongodb.org/downloads Linux Installation deployment:

1. Download: #wgethttps://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.2.1.tgz

2, Decompression: #tar –zxvfmongodb-linux-x86_64-3.2.1.tgz

#mv Mongodb-linux-x86_64-3.2.1/usr/local/mongodb

3. Add PATH: #exportPATH =/usr/local/mongodb/bin: $PATH

4. Create database directory: #mkdir –p/data/db

5. Start MongoDB Service:

#mongod If the database directory is not/data/db, you can specify it by-dbpath

You can also create a startmongo.sh script that starts with a background process, with the following script contents

Cd/usr/local/mongodb/bin ./mongod &

6. Using the command to connect MongoDB: #cd/usr/local/mongodb/bin

#./mongo

7, Web user interface: MongoDB provides a simple HTTP user interface, if you want to enable, you need to increase the-rest parameter at startup

#./mongod–dbpath=/data/db–rest WinDOS Deployment installation: Slightly MONGO cluster configuration

1, Replica set cluster (replica cluster), the advantage of this kind of cluster is high availability, prevent single point of failure.

The prerequisite is that you have downloaded MONGO and completed setting the environment variable

Create a mongo_18000.conf file

Port = 18000 DBPath =/data/mongodb/18000 LogPath =/data/mongodb/18000.log Logappend = True Directoryperdb = True Journal = True Fork = True Replset = myrs Oplogsize = 1024

Create a mongo_18001.conf file

Port = 18001 DBPath =/data/mongodb/18001 LogPath =/data/mongodb/18001.log Logappend = True Directoryperdb = True Journal = True Fork = True Replset = myrs Oplogsize = 1024

Parameter description:

DBPath: Storing Data Directory

LogPath: Log Data Directory

Pidfilepath:pid file

KeyFile: Used to validate files between nodes, content must be consistent, permissions 600

DIRECTORYPERDB: Whether the database is stored in a directory

Logappend: Log Append method storage

Replset:replica Set's name

BIND_ID:MONGODB Bound IP Address

Port: Ports

Auth: Whether to turn on authentication

Oplogsize: Setting the size of the Oplog (MB)

Fork: Daemon Run, create process

Moprealloc: Whether data file pre-allocation is disabled

Maxconns: Maximum number of connections, default 2000

Create a startup file startmongors.sh

Mongod-f/usr/local/mongodb/mongo_18000.conf & Mongod-f/usr/local/mongodb/mongo_18001.conf &

Start mongodb:#./startmongors.sh

Configured on the primary node: #mongo 127.0.0.1 18000

>use Admin

> cfg={_id: "myrs", Members:[{_id:0,host: ' 127.0.0.1:18000 ', priority:1},{_id:1,host: ' 127.0.0.1:18001 ', priority : 2}]}

> rs.initiate (CFG)

>rs.status ()

2. master-Slave mode cluster

3. Shard Mode Cluster

4. Shard + Replica Cluster
