zookeeper 安装教程

2020-06-29

brew安装

brew install zookeeper

==> Downloading https://homebrew.bintray.com/bottles/zookeeper-3.4.13.mojave.bottle.tar.gz
==> Downloading from https://akamai.bintray.com/d1/d1e4e7738cd147dceb3d91b32480c20ac5da27d129905f336ba51c0c01b8a476?__gd

==> Pouring zookeeper-3.4.13.mojave.bottle.tar.gz
==> 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
==> Summary
🍺  /usr/local/Cellar/zookeeper/3.4.13: 244 files, 33.4MB

查看zookeeper 信息


brew info zookeeper

	Install HEAD version
==> Caveats
To have launchd start zookeeper now and restart at login:
  brew services start zookeeper

brew nstall 完成之后 对应配置如下


/usr/local/etc/zookeeper
chengkejundeMacBook-Pro:zookeeper c.kj$ ls
defaults		log4j.properties	zoo.cfg			zoo_sample.cfg
chengkejundeMacBook-Pro:zookeeper c.kj$

修改 zoo.cfg 搭建集群修改这些配置 因为只需要搭建一个伪集群所以没有修改其中参数,感兴趣的可以自己搜索一些教程~


# 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/Cellar/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

为了能够在任意目录启动zookeeper集群,我们需要配置环境变量.
ps:你也可以不配,这不是搭建集群的必要操作,只不过如果你不配置环境变量,那么每次启动zookeeper需要到安装文件的 bin 目录下去启动。
配置如下


chengkejundeMacBook-Pro:data c.kj$ open -e ~/.bash_profile
chengkejundeMacBook-Pro:data c.kj$ cat ~/.bash_profile
export M3_HOME=/usr/local/mvn/apache-maven-3.3.9
export GRADLE_HOME=/usr/local/Cellar/gradle/5.2.1
export SCALA_HOME=/usr/local/Cellar/scala/2.12.8
export ZK_HOME=/usr/local/Cellar/zookeeper/3.4.13
export PATH=$M3_HOME/bin:$PATH:$GRADLE_HOME/bin:$SCALA_HOME/bin:$ZK_HOME/binchengkejundeMacBook-Pro:data c.kj$
chengkejundeMacBook-Pro:data c.kj$
chengkejundeMacBook-Pro:data c.kj$ source ~/.bash_profile

启动命令: zkServer start

停止命令: zkServer stop

重启命令: zkServer restart

查看集群节点状态: zkServer status


chengkejundeMacBook-Pro:~ c.kj$ zkServer start
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Starting zookeeper ... already running as process 49422.
chengkejundeMacBook-Pro:~ c.kj$ zkServer status
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Mode: standalone
chengkejundeMacBook-Pro:~ c.kj$

end ~
