在mac OSX中安装启动zookeeper
安装
zookeeper支持brew安装。
$brew info zookeeper zookeeper: stable 3.4.6 (bottled), HEAD Centralized server for distributed coordination of services https://zookeeper.apache.org/ /usr/local/Cellar/zookeeper/3.4.6_1 (208 files, 13M) * Poured from bottle From: https://github.com/Homebrew/homebrew/blob/master/Library/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 at login: ln -sfv /usr/local/opt/zookeeper/*.plist ~/Library/LaunchAgents Then to load zookeeper now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.zookeeper.plist Or, if you dont want/need launchctl, you can just run: zkServer start
安装
$brew install zookeeper ==> Downloading https://homebrew.bintray.com/bottles/zookeeper-3.4.6_1.mavericks.bottle.2.tar.gz ######################################################################## 100.0% ==> Pouring zookeeper-3.4.6_1.mavericks.bottle.2.tar.gz ==> Caveats To have launchd start zookeeper at login: ln -sfv /usr/local/opt/zookeeper/*.plist ~/Library/LaunchAgents Then to load zookeeper now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.zookeeper.plist Or, if you dont want/need launchctl, you can just run: zkServer start ==> Summary /usr/local/Cellar/zookeeper/3.4.6_1: 207 files, 13M
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
$less -N /usr/local/etc/zookeeper/zoo.cfg 1 # The number of milliseconds of each tick 2 tickTime=2000 3 # The number of ticks that the initial 4 # synchronization phase can take 5 initLimit=10 6 # The number of ticks that can pass between 7 # sending a request and getting an acknowledgement 8 syncLimit=5 9 # the directory where the snapshot is stored. 10 # do not use /tmp for storage, /tmp here is just 11 # example sakes. 12 dataDir=/usr/local/var/run/zookeeper/data 13 # the port at which the clients will connect 14 clientPort=2181 15 # the maximum number of client connections. 16 # increase this if you need to handle more clients 17 #maxClientCnxns=60 18 # 19 # Be sure to read the maintenance section of the 20 # administrator guide before turning on autopurge. 21 # 22 # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance 23 # 24 # The number of snapshots to retain in dataDir 25 #autopurge.snapRetainCount=3 26 # Purge task interval in hours 27 # Set to "0" to disable auto purge feature 28 #autopurge.purgeInterval=1
启动服务
执行命令zkServer
$zkServer 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 JMX enabled by default Using config: /usr/local/etc/zookeeper/zoo.cfg Error contacting service. It is probably not running. $ zkServer start 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 Welcome to ZooKeeper!
