How to bind all Kafka tcp port to private net address
My version is kafka_2.11-0.9.0.0. I find that the kafka listen on multi tcp
port on a linux server.
[gdata@gdataqosconnd2 kafka_2.11-0.9.0.0]$ netstat -plnt|grep java
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 10.105.7.243:9092 0.0.0.0:*
LISTEN 31011/java
tcp 0 0 0.0.0.0:51367 0.0.0.0:*
LISTEN 31011/java
tcp 0 0 0.0.0.0:1105 0.0.0.0:*
LISTEN 31011/java
tcp 0 0 0.0.0.0:42592 0.0.0.0:*
LISTEN 31011/java
10.105.7.243:9092 is the broker's port.0 0.0.0.0:1105 is the jmx port that
I set in the start script.
But I dont know what is the 0 0.0.0.0:51367 and 0 0.0.0.0:42592. And more
tricky, the port will change after restarting of the kafka process.
So I want to know how to bind the kafka port to private interface just
like '10.105.7.243'.
If I can not bind them, can I set the fixed listened port number?

############################# Log Flush Policy #############################
# Messages are immediately written to the filesystem but by default we only
fsync() to sync
# the OS cache lazily. The following configurations control the flush of
data to disk.
# There are a few important trade-offs here:
# 1. Durability: Unflushed data may be lost if you are not using
replication.
# 2. Latency: Very large flush intervals may lead to latency spikes when
the flush does occur as there will be a lot of data to flush.
# 3. Throughput: The flush is generally the most expensive operation,
and a small flush interval may lead to exceessive seeks.
# The settings below allow one to configure the flush policy to flush data
after a period of time or
# every N messages (or both). This can be done globally and overridden on a
per-topic basis.
# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages=10000
# The maximum amount of time a message can sit in a log before we force a
flush
#log.flush.interval.ms=1000
############################# Log Retention Policy
#############################
# The following configurations control the disposal of log segments. The
policy can
# be set to delete segments after a period of time, or after a given size
has accumulated.
# A segment will be deleted whenever *either* of these criteria are met.
Deletion always happens
# from the end of the log.
# The minimum age of a log file to be eligible for deletion
log.retention.hours=48
# A size-based retention policy for logs. Segments are pruned from the log
as long as the remaining
# segments don't drop below log.retention.bytes.
#log.retention.bytes=1073741824
# The maximum size of a log segment file. When this size is reached a new
log segment will be created.
log.segment.bytes=1073741824
# The interval at which log segments are checked to see if they can be
deleted according
# to the retention policies
log.retention.check.interval.ms=300000
# By default the log cleaner is disabled and the log retention policy will
default to just delete segments after their retention expires.
# If log.cleaner.enable=true is set the cleaner will be enabled and
individual logs can then be marked for log compaction.
log.cleaner.enable=false
############################# Zookeeper #############################
# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.

Posted by costa xu <xx...@gmail.com>.
yes, the host.name is useless in this case.
Even if I set the host.name=private ip, the broker also bind on 0.0.0.0

RE: How to bind all Kafka tcp port to private net address
Posted by John Prout <Jo...@acxiom.com>.
I have set the host.name option in the server.properties file, but the Broker is still binding to all interfaces, and logging that's what it is doing.
This is with kafka 0.9.0 running on a Solaris 10 server with 3 Virtual interfaces installed, in addition to the Physical interface.
