This guide will be updated as soon as possible.

In this guide I will show some simple steps of how to set up a MongoDB installation in a replication on Windows Server 2012.

For this setup, I used the following three servers that have Windows 2012 Standard edition installed.

bf-mongodb01: 192.168.1.42 / 4gb ram / 2 cpu
bf-mongodb02: 192.168.1.43 / 4gb ram / 2 cpu
bf-mongodb03: 192.168.1.44 / 4gb ram / 2 cpu

Workgroup: bf-mongodb

They all have to be in the same workgroup or in the same domain. If they are not then you have to add all the servers in your hosts file so mongodb knows how to connect to them.

Also, for this example I installed everything as “Administrator”. Depending on how you are going to use it I would suggest to make a non admin user to run all this.

So lets start!

Step 1: Download MongoDB (on all three servers)
MongoDB provides Windows installer packages, so simply download their msi file from their website http://www.mongodb.org/.
https://fastdl.mongodb.org/win32/mongodb-win32-x86_64-2008plus-2.6.3-signed.msi

Even if it does say ‘Windows 2008’ it does work perfect on Windows 2012!

Step 2: Install MongoDB
Just follow the pictures below to install MongoDB. You have to do this on all three servers.


Just press ‘next’.


Read the license and then tick the box you accept the license and press ‘next’.


Press you wish to install the “Complete” version.


Just press ‘Install’ to start the installation.


You should now have finished the installation so simpely press ‘Finish’.

Remember, you have to do this on all three of your servers.

Step 3: Create a database and log directory (on all three servers)
Create the following directories:
C:\basefarm\mongodb\data\db
C:\basefarm\mongodb\data\log

Step 4: Fix the Windows firewall (on all three servers).
Go to your “Control Panel” and then click on “Network and Internet”. Once there, click on “Network and Sharing Center” and then at the right side at the bottom click on “Windows Firewall”.

You should now see your Windows firewall like this:

On this window click on “Allow an app or feature trough Windows Firewall” your window will change and click on this window on “Allow another app..” and fill everything in as shown below.

If everything looks as above press on “OK” to close the firewall configuration window.

Step 5: Create a MongoDB config file (on all three servers)
Open a notepad and add the following information:
logpath=C:\basefarm\mongodb\data\log\mongod.log
dbpath=C:\basefarm\mongodb\data\db
bind_ip=0.0.0.0
replSet=bf

Once added, save the file as “mongod.cfg” in the directory:
“C:\Program Files\MongoDB 2.6 Standard\”
You should end up with
“C:\Program Files\MongoDB 2.6 Standard\mongod.cfg”

Step 6: Create a service that will automatically start MongoDB (on all three servers)
Open a Command Prompt and type the following:
sc.exe create MongoDB binPath= "\"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB 2.6 Standard\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"

This should create a service for MongoDB. If you did it correct, it should look like this:

Step 7: Start MongoDB (on all three servers)
Just restart the server and MongoDB should automatically start, so it is a good test that the previous commands worked.

Step 8: Go into the MongoDB shell (only on server one)
Go to “C:\Program Files\MongoDB 2.6 Standard\bin” and double click on “mongo”. A terminal window should open that looks like this:

Step 9: Create the replica set in the mongo shell. (only on server one)
While being in the mongo shell type the following commands:
rs.initiate()
rs.add("bf-mongodb02:27017")
rs.add("bf-mongodb03:27017")
cfg = rs.conf()
cfg.members[0].priority = 100
cfg.members[1].priority = 50
cfg.members[2].priority = 50
rs.reconfig(cfg)

Step 10: Test if your configuration is working. (only on server one)
in the mongo shell still type:
rs.status()

You should see something like this if everything is correct:

Congratulations, you now have successfully installed MongoDB on Windows and you have set it up in a replication :)! Now, let’s test that the replication works by creating a database on the master (mongodb01).

Step 11: Create a test collection with some data on the master (only on server one)
In the mongo shell type the following:
use basefarm
bf = { name : "basefarmblog" }
db.Data.insert( bf )
show dbs
show collections
db.Data.find()

You should see something like this:

As you can see “show dbs” did show you have a database Basefarm, “show collections” shows you have the collection Data and “db.Data.find()” shows that the Data collections contains the information “basefarmblog”.

If everything did work as intended, all this should have been replicated to your servers mongodb02 and mongodb03, so let’s test it!

Step 12: Check if the slaves have data (on server two or three)
Go to your server two or three and open a mongo shell by double clicking on the “mongo” file and run the following commands:
show dbs
rs.slaveOk()
use basefarm
show collections
db.Data.find()

If everything worked you should see the following:

The command “rs.slaveOk()” I used because this will you allow to read from the slave. By default this is not enabled.

Well, this was it. Everything worked and you can now use your MongoDB replica set for anything you like!

As always, if you have any improvements or see any mistakes, please let me know. I am always open to hear your ideas or to learn from you!

    hi Sjir,

    I have tried to follow your instructions, but stuck at step 6 and 7.

    I am installing MongoDB 2.6 64bit server on windows 2012 R2.

    I am getting error 1053 when trying to start MongoDB service as it won’t start automatically after reboot.

    sorry I would like to add answer to my question above.

    You blog has perfectly worked for my.
    One thing I would like to mention, just before step 8 adding port 27017 on server 2012 firewall inbound connection has fixed my issue. Even though I added mongod as per your instructions.

    Hope more people can benefit from your hard work of putting together excellent instructions.

    Regards,
    shoaib
