Apache Zookeeper Cookbook
Installs and configures Apache Zookeeper.
View the Change Log to see what has changed.
Supports
- CentOS
- Ubuntu
Usage
Using the default attributes will setup a single Zookeeper server in standalone mode.
If you are wanting to setup Zookeeper in a multi-server cluster make sure to fill out the
node["zookeeper"]["servers"]
attribute with an array of fqdn/hostnames/ips of your zookeeper
servers. This array is used to calculate the server ids for each zookeeper.
You can also provide the server ids yourself by including values for the attributes
node["zookeeper"]["zoo.cfg"]["server.[ID]"]
. If this is done you don't have to provide the
node["zookeeper"]["servers"]
attribute.
What does the installation look like
By default the installation will look like,
zkCli | /usr/bin/zkCli - The Zookeeper cli binary command
/opt/zookeeper/* - All of Zookeeper's files (config, binaries, event handlers, logs...)
/etc/init.d/zookeeper - An init.d script to start/stop zookeeper. You can use service
zookeeper [start|stop|restart|status] instead
Unique Quorum and Leader Election Ports
It is possible to provide unique quorum and leader election ports via node["zookeeper"]["servers"]
attribute
or node["zookeeper"]["zoo.cfg"]["server.[ID]"]
by specifying the hostname followed by the quorum and
leader election ports like this,
node["zookeeper"]["servers"] = ["host1:2188:3188", "host2:2188:3188", "host3:2188:3188"]
or
node["zookeeper"]["zoo.cfg"]["server.1"] = "host1:2188:3188"
...
Environment Variables
Should note that the zkServer.sh
and other various scripts provided by zookeeper taken in various environment variables to tweak
runtime settings. Here are some,
-
ZOO_LOG_DIR
: Overwrites log4jzookeeper.log.file
. Defaults to.
if not set which is why we provide a default value for it to thenode["zookeeper"]["log_directory"]
value. -
ZOO_LOG4J_PROP
: Overwrites log4jzookeeper.root.logger
. Defaults to'INFO, CONSOLE'
if not set which is why we provide a default value for it'INFO,CONSOLE,ROLLINGFILE'
-
JMXDISABLE
: Disables jmx. Defaults to enabling JMX. To disable set to any value -
SERVER_JVMFLAGS
: JVM flags for the server process
