Installing MongoDB on Linux

Installed version: 3.0.7

Installation machine: All machines

Installation process:

1. Use the Hadoop account to extract the/opt/hadoop/directory:

$ TAR-ZXVF mongodb-${version}.tar.gz-c/opt/hadoop/

2. Set up a soft link:

$ ln-s/opt/hadoop/mongodb-${version}/opt/hadoop/mongodb

3. Configure the environment variables and make them effective:

# Vim/etc/profile

Export Mongodb_home=/opt/hadoop/mongodb

Export Path=${mongodb_home}/bin: $PATH

# Source/etc/profile

4. Create the data-related directory under the/opt/hadoop/mongodb/directory (you must ensure that the directory is empty):

$ mkdir-p/opt/hadoop/mongodb/data/configsvr

$ mkdir-p/opt/hadoop/mongodb/data/rs0-0

$ mkdir-p/opt/hadoop/mongodb/data/rs1-0

5. Modify the configsvr.conf file in the Conf directory:

$ vim/opt/hadoop/mongodb/conf/configsvr.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/configsvr.log"

Pidfilepath: "/opt/hadoop/mongodb/configsvr.pid"

DbPath: "/opt/hadoop/mongodb/data/configsvr"

6. Continue to modify the mongos.conf file:

$ vim/opt/hadoop/mongodb/conf/mongos.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/mongos.log"

Pidfilepath: "/opt/hadoop/mongodb/mongos.pid"

7. Continue to modify the rs0.conf file:

$ vim/opt/hadoop/mongodb/conf/rs0.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/rs0-0.log"

Pidfilepath: "/opt/hadoop/mongodb/rs0-0.pid"

DbPath: "/opt/hadoop/mongodb/data/rs0-0"

8. Continue to modify the rs1.conf file:

$ vim/opt/hadoop/mongodb/conf/rs1.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/rs1-0.log"

Pidfilepath: "/opt/hadoop/mongodb/rs1-0.pid"

DbPath: "/opt/hadoop/mongodb/data/rs1-0"

9. Copy the MongoDB to the BASELINE02 machine on the BASELINE01 and modify the environment variables as per step 3:

$ scp-r/opt/hadoop/mongodb-${version} [email protected]2:/opt/hadoop

$ ln-s/opt/hadoop/mongodb-${version}/opt/hadoop/mongodb

10. Modify the folder name in the data directory:

$ mv/opt/hadoop/mongodb/data/rs0-0/opt/hadoop/mongodb/data/rs0-1

$ mv/opt/hadoop/mongodb/data/rs1-0/opt/hadoop/mongodb/data/rs1-1

11. Modify the Rs0.conf file on BASELINE02:

$ vim/opt/hadoop/mongodb/conf/rs0.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/rs0-1.log"

Pidfilepath: "/opt/hadoop/mongodb/rs0-1.pid"

DbPath: "/opt/hadoop/mongodb/data/rs0-1"

12. Modify the rs1.conf file on BASELINE02:

$ vim/opt/hadoop/mongodb/conf/rs1.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/rs1-1.log"

Pidfilepath: "/opt/hadoop/mongodb/rs1-1.pid"

DbPath: "/opt/hadoop/mongodb/data/rs1-1"

13. Copy the MongoDB to the BASELINE03 machine on the BASELINE01:

$ scp-r/opt/hadoop/mongodb-${version} hadoop@baseline03:/opt/hadoop

$ ln-s/opt/hadoop/mongodb-${version}/opt/hadoop/mongodb

14. Modify the folder name in the data directory:

$ mv/opt/hadoop/mongodb/data/rs0-0/opt/hadoop/mongodb/data/rs0-2

$ mv/opt/hadoop/mongodb/data/rs1-0/opt/hadoop/mongodb/data/rs1-2

15. Modify the rs0.conf file on baseline03:

$ vim/opt/hadoop/mongodb/conf/rs0.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/rs0-2.log"

Pidfilepath: "/opt/hadoop/mongodb/rs0-2.pid"

DbPath: "/opt/hadoop/mongodb/data/rs0-2"

16. Modify the rs1.conf file on baseline03:

$ vim/opt/hadoop/mongodb/conf/rs1.conf

Modify the following content

Path: "/opt/hadoop/mongodb/logs/rs1-2.log"

Pidfilepath: "/opt/hadoop/mongodb/rs1-2.pid"

DbPath: "/opt/hadoop/mongodb/data/rs1-2"

17.RS0 configuration:

Three machines sequentially start the Mongod service:

$ Mongod--config/opt/hadoop/mongodb/conf/rs0.conf

18. Perform a connection to the Mongod instance on BASELINE01:

$ MONGO baseline01:27017

After the connection is successful, execute:

>rs0conf = {

_id: "Rs0",

Members: [

{

_id:0,

Host: "baseline01:27017"

}

]

}

>rs.initiate (rs0conf)

>rs.add ("baseline02:27017")

>rs.add ("baseline03:27017")

>rs.status ()//half minute after the execution of the command, if a master two from the Rs0 configuration is successful

RS1 configuration:

Three machines sequentially start the Mongod service:

$ Mongod--config/opt/hadoop/mongodb/conf/rs1.conf

To perform a connection to the Mongod instance on BASELINE01:

$ MONGO baseline01:27018

>rs1conf = {

_id: "Rs1",

Members: [

{

_id:0,

Host: "baseline01:27018"

}

]

}

>rs.initiate (rs1conf)

>rs.add ("baseline02:27018")

>rs.add ("baseline03:27018")

>rs.status ()//half minute after the execution of the command, if a master two from the Rs1 configuration is successful

19. Three machines start the configuration server separately:

$ Mongod--config/opt/hadoop/mongodb/conf/configsvr.conf

20. Three machines start the MONGOs route separately:

$ MONGOs--config/opt/hadoop/mongodb/conf/mongos.conf

21. Connect to the MONGOs on the BASELINE01:

$ MONGO baseline01:27000

22. Switch to the Admin database and add shards:

mongos> Use admin

Mongos>db.runcommand ({addshard: "rs0/baseline01:27017,baseline02:27017,baseline03:27017"})

Mongos>db.runcommand ({addshard: "rs1/baseline01:27018,baseline02:27018,baseline03:27018"})

23. View the Shard Status:

Mongos>db.runcommand ({listshards:1})

24. Start the Shard for the TestDB database:

Mongos>db.runcommand ({enablesharding: "TestDB"})

Mongos>db.runcommand ({shardcollection: "Testdb.test_table", Key:{id:1}})

25. Connect to the MONGOs on the BASELINE01:

$ MONGO baseline01:27000

26 Test Insert Data:

Mongos>use TestDB

Mongos>for (var i = 1; I <= 50000; i++) Db.test_table.insert ({"id": I, "name": "str" +i, "date": New Date ()})

Writeresult ({"ninserted": 1})

Mongos>db.test_table.stats ()

View shard Status, if there is data on Rs0 and RS1, indicating successful deployment
