Installs and configures N number of Cassandra nodes in a cluster on Rackspace Public Cloud & (AWS WIP)
Requirements
- Ansible > v1.8
- Rackspace Public Cloud account
Configuration and files
-
config/group_vars/all: contains global variables for cluster settings
-
prov.sh: Builds the entire stack -->
\ansible-playbook config/db-server.yml -f 20
\ansible-playbook -i scripts/rax.py config/db.yml -f 20
\ansible -vvvv -u root -i scripts/rax.py db -m ping -f 20 -
ping.sh: Pings all nodes with verbose output
-
delete.sh: Deletes all nodes in cluster with name defined in "all" group_vars.
Gotcha's and bugs
- if a node fails to build on the initial run, you can rerun the same prov.sh but will need to cleanup the directories and restart cassandra again
ansible -vvvv -u root -i scripts/rax.py ds_db -m shell -a "rm -rf /var/lib/cassandra/*" -f 20 ansible -vvvv -u root -i scripts/rax.py ds_db -m shell -a "service cassandra restart" -f 20
