在mac OSX中安装启动zookeeper

安装

zookeeper支持brew安装

➜  ~ brew info zookeeper
zookeeper: stable 3.4.8 (bottled), HEAD
Centralized server for distributed coordination of services
https://zookeeper.apache.org/
Not installed
From: https://mirrors.tuna.tsinghua.edu.cn/git/homebrew-core.git/Formula/zookeeper.rb
==> Options
--with-perl
    Build Perl bindings
--with-python
    Build with python support
--HEAD
    Install HEAD version
==> Caveats
To have launchd start zookeeper now and restart at login:
  brew services start zookeeper
Or, if you don't want/need a background service you can just run:
  zkServer start

 

安装

➜  ~ brew install zookeeper
==> Downloading https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles/bottles/zookeeper-3.4.8.el_capitan.bottle.tar.gz

  zkServer start
==> Summary
🍺  /usr/local/Cellar/zookeeper/3.4.8: 237 files, 17.6M

安装后，在/usr/local/etc/zookeeper/目录下，已经有了缺省的配置文件。

➜  ~ ls /usr/local/etc/zookeeper
defaults         log4j.properties zoo.cfg          zoo_sample.cfg

 

缺省配置[/usr/local/etc/zookeeper/zoo.cfg] 内容如下

➜  / cat /usr/local/etc/zookeeper/zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/usr/local/var/run/zookeeper/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

 

启动服务

执行zkServer命令

➜  / zkServer
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Usage: ./zkServer.sh {start|start-foreground|stop|restart|status|upgrade|print-cmd}
➜  / zkServer status
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Error contacting service. It is probably not running.
➜  / zkServer start
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Starting zookeeper ... STARTED

 

查看zookeeper运行及状态

安装后，可以看到zookeeper提供了zkCli等工具进行.

➜  / zkCli
Connecting to localhost:2181
