Cassandra - How to Install Cassandra 2.2 on AWS EC2

AMI: Amazon Linux AMI 2015.09 (HVM), SSD Volume Type - ami-e3106686
Instance Type: i2.2xlarge

Prerequisites:
- Yum Package Management application installed.
- Root or sudo access to the install machine.
- Latest version of Oracle Java SE Runtime Environment (JRE) 8 or OpenJDK 7.
- Python 2.6+ (if installing OpsCenter).

Steps:
1. Prepare partitions, I have 2x800 SSD as my data disk:

## Note: The SSD-based instance storage in I2 instances do not come pre-formatted with a FS, you have to use a mkfs utility to mount the device as a file system.

## Create ext4 filesystem
# mkfs.ext4 /dev/xvdb
# mkfs.ext4 /dev/xvdc

## Update /etc/fstab
# vim /etc/fstab, add
/dev/xvdb        /mnt/data00            ext4    defaults,nosuid,nodev,noatime           0       0
/dev/xvdc        /mnt/data01            ext4    defaults,nosuid,nodev,noatime           0       0

## Create mount points
# mkdir /mnt/{data00,data01}

## Mount new FS
# mount -a

## Verify
# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1       25G  1.2G   24G   5% /
devtmpfs         30G   68K   30G   1% /dev
tmpfs            31G     0   31G   0% /dev/shm
/dev/xvdb       734G   69M  697G   1% /mnt/data00
/dev/xvdc       734G   69M  697G   1% /mnt/data01

2.  Add the DataStax Community repository to the /etc/yum.repos.d/datastax.repo:

# vim /etc/yum.repos.d/datastax.repo
Add
[datastax]
name = DataStax Repo for Apache Cassandra
baseurl = http://rpm.datastax.com/community
enabled = 1
gpgcheck = 0

# yum list | grep cassandra
apache-cassandra11.noarch             1.1.12-1                      datastax
cassandra12.noarch                    1.2.19-1                      datastax
cassandra20.noarch                    2.0.17-1                      datastax
cassandra21.noarch                    2.1.11-1                      datastax
cassandra21-tools.noarch              2.1.11-1                      datastax
cassandra22.noarch                    2.2.3-1                       datastax
cassandra22-tools.noarch              2.2.3-1                       datastax

3. Install cassandra22

# yum install cassandra22
# yum install cassandra22-tools

4. Install jna:

# yum install jna

5. Now you can configure cassandra.yaml file and start cassandra service.
