Adobe Experience Manager 6 with a MongoDB Setup

With AEM 6 the persistence layer which is used to store content, configurations, and program code, is called a MicroKernel (MK). AEM 6 introduced a new MicroKernel and here's what you should know.

AEM 6 introduced a new MicroKernel (MongoMK) which allows the use of MongoDB as a repository. Further MicroKernels may be added along the line but are not fully confirmed yet. In this article we will be looking at a very basic local MongoDB setup.

A simple and local MongoDB with AEM

Requirements:

  • Linux or Mac
  • Java 7 (preferably JDK and possibly from Oracle so you can make full use of JMX)
  • An AEM 6 license
  • An AEM 6 crx-quickstart jar
  • The mongodb binaries (linked below)

Follow the steps below to get an AEM author (or publish) up and running using a local MongoDB

1. Prepare a folder structure (sample) as below:

    ./aem_600_mongodb ./aem_600_mongodb/mongodb ./aem_600_mongodb/mongodb/data ./aem_600_mongodb/mongodb/logs

 

2. Download MongoDB for Mac OSX or other OS (configs in this guide also work with Linux)

http://www.mongodb.org/downloads

 

3. extract the packages content directly into the mongodb directory as created under point 1. -> ( ./aem_600_mongodb/mongodb/bin should then exist )

4. in your mongodb directory, parallel to the data & logs & bin directory create the mongod.cfg file

mongod.cfg 

bind_ip = 127.0.0.1
port = 27017
quiet = false
dbpath = ../data
logpath = ../logs/mongod.log
logappend = true
journal = true
directoryperdb = true
rest = true
httpinterface = true




 

5. now place your license.properties & AEM 6 quickstart jar in your base directory (in this case ./aem_600_mongodb)

6. extract the AEM 6 jar file (java -jar aem-6.0.0.20140515.jar -unpack)

 

7. edit the start script under ./aem_600_mongodb/crx-quickstart/bin and add the following properties

CQ_RUNMODE='author,crx3mongo' -> crx3mongo is added here
CQ_JVM_OPTS='-server -Xmx1024m -XX:MaxPermSize=256M -Djava.awt.headless=true -Doak.mongo.uri=mongodb://localhost:27017' -> -Doak.mongo.uri=mongodb://localhost:27017 is added here

 

8. once the above steps are completed go to your bin directory in your mongodb directory and start mongo db & tail the log

./mongod --config ../mongod.cfg && tail -f ../logs/mongod.log

 

9. now start your AEM from the ../crx-quickstart/bin directory and tail the log 

./start && tail -f ../error.log

 

10. once your AEM is started and everything has been created you got an AEM running on MongoDB

 

11. for administration purposes have a look at using the robomongo app: http://robomongo.org/

 

he Adobe documentation and MongoDB documentation is your best bet for further details.
