This role sets up keepalived for an standard setup of:
- One virtual IP
- Two hosts
You just need to provide an small amount of information to have it running
- Add "keepalived" role to both hosts
- Add variable keepalived_role: "master" | "slave" to the appropiate hosts
- Add variable keepalived_shared_ip: "floating IP address" to both hosts
Other variables can be configured, overwriting defaults/main.yml
Keepalived can watch processes to influence on which node should be the master. Setting variable "keepalived_check_process" to the name of the process will do. I use keepalived to give high availability to haproxy, so I use.
keepalived_check_process: "haproxy"
Works with centos/redhat and Debian/Ubuntu
keepalived_auth_pass: "1111"
keepalived_role: "MASTER"
keepalived_router_id: "52"
keepalived_shared_iface: "eth0"
keepalived_shared_ip: "192.168.1.1"
keepalived_check_process: "keepalived"
keepalived_priority: "100"
keepalived_backup_priority: "50"
- hosts: s1
roles:
- { role: keepalived, keepalived_shared_ip: "192.168.1.1", keepalived_role: "master" }
- hosts: s2
roles:
- { role: keepalived, keepalived_shared_ip: "192.168.1.1", keepalived_role: "slave" }
Quite simple if you have vagrant installed.
