This is a fork of the RA with redis. The redis RA only works with redis 2.6++
following corosync/cib settings should work with the redis resource agent:
primitive redis ocf:heartbeat:redis \
params client_binary="/usr/bin/redis-cli -a 123234" pid="/var/run/redis/redis-server.pid" \
meta target-role="Master" \
op monitor interval="30s" role="Slave" timeout="30s" on-fail="restart"
ms redis_ms redis \
meta clone-max="2" target-role="Master" notify="true"
This is a Setup if you want to use a secound instance of RedisDB
primitive redis_secound ocf:heartbeat:redis \
params client_binary="/usr/bin/redis-cli -a 123123" \
config="/etc/redis/cache.conf" \
pid="/var/run/redis/cache.pid" \
socket="/var/run/redis/cache.sock" \
port="6380" \
meta target-role="Master" \
op monitor interval="30s" role="Slave" timeout="30s" on-fail="restart"
ms redis_secound_ms redis_secound \
meta clone-max="2" target-role="Master" notify="true"
client_binary for this setting is for authentification redis-cli -a 123234 = for authentification
The master and slave definition, came from the skript. Do not use config settings in the redis.conf to define the master host.
*You must set target-role="Master" !
Serverals of redis instanzes on one note: That sould work, but not tested yet. You must define socket option and define a other port.
Timeout - in premitive the option timeout="30s" defines also the absolut timeout of syncing of a slave node from a master. Be carefull of this setting
- ocf-tester -n redis -o socket /tmp/tmp.socket
- pkill -9 redis-server on master or on slave host.
- Start of min two nodes, the skript can enforce the decision strongly. ( see post-start and promote)
socket: Imported to use the resource agent port: Master and Slave must run under the same port pid: Pid file binary: The Server binary client_binary: The client binary to control and connect to the redis db. config: the path to the config file user: username for the process group: groupname log: the stdout log file.
- Serverlas of redis instanzes in one Master/Slave setup with different ports.
