This article describes step by step how to run a mongodb instance with Zadara VPSA.
It assumes a Zadara account and VPSA was already created.
If you need to create a Zadara account please visit the link below:
Once the Zadara account and VPSA is created it is time to create a mongodb environment.
Launch MongoDB instance from AWS market place
1 - Go to AWS marketplace to the 10gen's page
2 - Click continue
3 - Click on tab Launch with EC2 console
4 - choose US East and press the button "Launch with EC2 console"
5 - you should see the AWS cloud console open on Request Instances Wizard, click Continue
6 - Choose the size of the instance and VPC, with the appropriate subnet.
7 - Check the instance details and click Continue
8 - Add a value for the instance name and click continue
9 - choose the key pair and hit continue
10 - choose the default (or other) firewall configuration and click continue
11 - Click Launch!
Mount VPSA volumes to Mongodb instance
1 - Connect to your instance via ssh
2 - install iscsi initiator # sudo yum install iscsi-initiator-utils
3 - start iscsi service # sudo service iscsi start
4 - check the IQN of the initiator # cat /etc/iscsi/initiatorname.iscsi
5 - At this point iSCSI initiator is installed. Next, in order to attach VPSA volumes need to use iscsiadm to discover the target and add the CHAP Auth.
In order to restart iSCSI after boot do chkconfig # chkconfig iscsi on
6 - Got to the VPSA GUI/ Servers and click Connect
7 - Select Linux and iSCSI (you will see the instructions you need to run on the VM to connect to VPSA)
8 - Go back to the mongodb servers, copy/paste the wget command, the chmod and the vpsa_linux commands
9 - at this point if you hit in the VPSA GUI Servers /Refresh you should see the new linux server listed.
10 - go to VPSA GUI/Volumes, create a new volume and attach to the mongodb server
11 - on the mongodb server you should see the new device by typing #ls -l /dev/disk/by-path
12 - create a filesystem i.e. #sudo mkfs /dev/sda
13 - create a directory for data i.e. #sudo mkdir /mnt/data
14 - mount the new filesystem #sudo mount /dev/sda /mnt/data
15 - edit /etc/mongod.conf file and point the dbpath = /mnt/data
16 - change owner of data directory to mongod $ sudo chown mongod:mongod /mnt/data
17 - if desired create new volumes for journal and logs and adjust the mongod.conf file appropriately
1 - Run mongo db
$ sudo chkconfig mongod on
$ sudo /etc/init.d/mongod start
Starting mongod: [ OK ]
forked process: 1234
all output going to: /var/log/mongo/mongod.log
2 - Test with mongo shell
MongoDB shell version: 2.0.4
connecting to: test
