Playbooks:
site.yml: Complete installation from scratch of all Airavata components, including dependencies.
airavata.yml: Airavata only updates, with cleanup of the old installation, and restart of ZooKeeper server.
reset_firewall.yml: An example of deleting firewall rules.
single_airavata.yml: Playbook for single all_in_one airavata server update.
restart_rabbitmq.yml: Restart RabbitMQ server.
restart_airavata.yml: Restart ZooKeeper and Airavata servers.
restart_single_airavata.yml: Restart ZooKeeper and all-in-one single Airavata server.
hosts:
Server groups are defined. Each group (e.g. dbserver, apiserver, etc.) can contain multiple servers. Variables defined under [airavata:vars] are used for the airavatar-server.properties file. For example, if multiple servers are deployed of a single component, say dbserver, for load-balancing purpose, the variable db_server defined under [airavata:vars] should point to the load-balancer address of the group of servers.
group_vars:
all: global variables used by all server groups, including Java and database information, as well as server ports. Set the variable “dbpassword” to the real database password before deployment.
airavata: airavata server group variables. “old_airavata_version” is used for cleanup of previous installations by airavata.yml. “myproxy_password” and “ssh_keypass” need to be set correctly before deployment. “local_ssh_key_path” is the local directory of airavata ssh key pairs to be copied to the airavata user home directory on remote machines.
rabbitmq: rabbimq server group variables.
zookeeper: zookeeper server group variables. Update any download_url and installation paths as desired before deployment.
roles:
roles/*/tasks/main.yml performs real work.
roles/*/handlers/main.yml restarts iptable when firewall rules are updated.
roles/*/meta/main.yml defines the dependency of individual airavata server component to the airavata_common role, with parameterized download url.
Internal Notes:
Make sure “local_ssh_key_path” exists on the local machine. SSH key pairs will NOT be copied over if they already exist on the remote machine, however it is important to have it on the local machine for Ansible to run through. The simplest way to have a version on the local machine is:
Default settings included in group_vars/* are conform with gw127, only airavata version variables and passwords need to be set correctly before deployment:
For deployment on gw111, copy the set of dev configurations as follows: cp group_vars/dev_all group_vars/all cp group_vars/dev_airavata group_vars/airavata cp group_vars/dev_zookeeper group_vars/zookeeper cp dev_hosts hosts Then update version variables and passwords as outline above.
Execute one of the playbooks as desired. For example:
To deploy a SNAPSHOT from local machine instead of downloadable URL, update following variables in group_vars/airavata:
* "airavata_version" should contain string "SNAPSHOT", e.g. "0.14-SNAPSHOT"
* Specify the absolute local path of SNAPSHOT in "airavata_local_snapshot_path"
