rabbitmq - custom config file - disk_free_limit not set properly - linux

Question

I've properly install (rpm based) a rabbitmq cluster (with clusterer plugin) in rhel7, create the "custom" configuration files:
/etc/rabbitmq/rabbitmq-env.config => env varialble
/etc/rabbitmq/rabbitmq.config => rabbitmq properties
The rabbitmq cluster works fine exept that my parameters are ignored, any idea why?
Thanks in advance for you help
kr,
O.
nb: if I set the paramertesr myself with a command like:
rabbitmqctl set_disk_free_limit "1g"
for the disk limit for example, it works but I want them to survive a "reboot" :/
Here are my configurations files:
# /etc/rabbitmq/rabbitmq-env.config
(..)
NODE_PORT=5672
NODENAME=rabbit#node1
RABBITMQ_CONFIG_FILE=/etc/rabbitmq/rabbitmq.config
(..)
cat << EOF > /etc/rabbitmq/rabbitmq.config
[
{kernel, [
]},
{rabbit, [
{cluster_nodes, ["rabbit#node1", "rabbit#node2", "rabbit#node3"], disc}
{tcp_listeners, [5672]},
{disk_free_limit, "1GB"},
{collect_statistics_interval, 10000},
{heartbeat, 30},
{cluster_partition_handling, autoheal},
{default_user, <<"guest">>},
{default_pass, <<"guest">>}
]},
{rabbitmq_clusterer, [
{config, [ {version,1}, {nodes,["rabbit#node1", "rabbit#node2", "rabbit#node3"]} ]}
]}
]
EOF

Answer 1

a little update for this topic, I had misconfigured my rabbitmq files; in order to have a working configuration, do the following modifications.
kr,
O.
For the environment file: we can get rid of the '.config' part in the file name as rabbitMQ add it anyway.
I my log file, I Had an error with "... /etc/rabbitmq/rabbitmq.config.config ... "
So keep the file with the .config extension (/etc/rabbitmq/rabbitmq.config) by set the env variable without the .config:
(..)
RABBITMQ_CONFIG_FILE=/etc/rabbitmq/rabbitmq
(..)
For the rabbit.config file: As I used the clusterer plugins, we can get rid of the line cluster_nodes.
Your file will look like this one:
cat << EOF > /etc/rabbitmq/rabbitmq.config
[
{kernel, [
]},
{rabbit, [
{tcp_listeners, [5672]},
{disk_free_limit, "1GB"},
{collect_statistics_interval, 10000},
{heartbeat, 30},
{cluster_partition_handling, autoheal}
]},
{rabbitmq_management, [
{http_log_dir,"/myapps/myproject/rabbitmq/logs"},
{listener, [{port, 15672 }]}
]},
{rabbitmq_clusterer, [
{config, [ {version,1}, {nodes,["rabbit#node01", "rabbit#node02", "rabbit#node03"]} ]}
]}
].
EOF
To verify your current config for the clusterer plugin you can use:
rabbitmqctl eval 'rabbit_clusterer:status().'
