在mac OSX中安装启动zookeeper

安装

zookeeper支持brew安装。

$brew info zookeeperzookeeper: stable 3.4.6 (bottled), HEADCentralized server for distributed coordination of serviceshttps://zookeeper.apache.org//usr/local/Cellar/zookeeper/3.4.6_1 (208 files, 13M) *  Poured from bottleFrom: 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==> CaveatsTo have launchd start zookeeper at login:  ln -sfv /usr/local/opt/zookeeper/*.plist ~/Library/LaunchAgentsThen to load zookeeper now:  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.zookeeper.plistOr, if you don't 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==> CaveatsTo have launchd start zookeeper at login:  ln -sfv /usr/local/opt/zookeeper/*.plist ~/Library/LaunchAgentsThen to load zookeeper now:  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.zookeeper.plistOr, if you don't 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/zookeeperdefaults        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

$zkServer JMX enabled by defaultUsing config: /usr/local/etc/zookeeper/zoo.cfgUsage: ./zkServer.sh {start|start-foreground|stop|restart|status|upgrade|print-cmd}$ zkServer  statusJMX enabled by defaultUsing config: /usr/local/etc/zookeeper/zoo.cfgError contacting service. It is probably not running.$ zkServer  startJMX enabled by defaultUsing config: /usr/local/etc/zookeeper/zoo.cfgStarting 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.

$zkCliConnecting to localhost:2181Welcome to ZooKeeper!JLine support is enabled[zk: localhost:2181(CONNECTING) 0] [zk: localhost:2181(CONNECTING) 0] WATCHER::WatchedEvent state:SyncConnected type:None path:null[zk: localhost:2181(CONNECTED) 0] ls[zk: localhost:2181(CONNECTED) 1] ls /[zookeeper][zk: localhost:2181(CONNECTED) 2] ls /zookeeper[quota][zk: localhost:2181(CONNECTED) 3] ls /zookeeper/quota[][zk: localhost:2181(CONNECTED) 4]
