Install MongoDB for integration with DMK

Create user

Commands are executed as mongodb user.

root $ groupadd mongodb -g 1500
root $ useradd --uid  1500 -d /home/mongodb -g mongodb  -m -s /bin/bash -p $(openssl passwd mongodb) mongodb

Create directory layout (change the version number)

The variables $MONGODB_BASE, $MONGODB_LOG and $MONGODB_BACKUP are defined in $DMK_HOME/etc/dmk.conf

Variable	Default Value
MONGODB_BASE	/u01/app/mongodb
MONGODB_LOG	/u02/mongodblog
MONGODB_BACKUP	/u90/backup

On the server is recommended to have the directories (mount points) as follows:

• /u01 : contains the DMK installation and MongoDB binaries

• /u02 : contains the database files and logs

• /u90 : contains the backups

export MONGODB_BASE=/u01/app/mongodb
export MONGODB_LOG=/u02/mongodblog
export MONGODB_BACKUP=/u90/backup
mkdir -p $MONGODB_BASE
mkdir -p $MONGODB_BASE/local
mkdir -p $MONGODB_BASE/admin
mkdir -p $MONGODB_BASE/etc
mkdir -p $MONGODB_BASE/product
mkdir -p $MONGODB_BASE/artifacts
mkdir -p /u02/mongodbdata
mkdir -p $MONGODB_LOG
mkdir -p $MONGODB_BACKUP
chown -R mongodb: /u01/
chown -R mongodb: /u02/
chown -R mongodb: /u90/

Packages install

The packages may change following the MongoDb version. See documentation for packages requirements

See https://www.mongodb.com/docs/manual/installation/ and https://www.mongodb.com/docs/manual/administration/install-on-linux/ for detailed information.
