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.
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)
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
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-18.104.22.16840515.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.
