Linux部署zookeeper

下载zookeeper(其中有不带bin的压缩包，但是最后没有成功，下载带bin的成功)

下载地址：http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.5.8/apache-zookeeper-3.5.8-bin.tar.gz

将文件解压到 /usr/local目录下，并重命名为apache-zookeeper

mv apache-zookeeper-3.5.8-bin apache-zookeeper

进入 apache-zookeeper目录，创建data和logs目录

mkdir data

mkdir logs

进入conf目录，拷贝文件zoo_sample.cfg，命名为zoo_cfg，只能是zoo_cfg

cp zoo_sample.cfg zoo.cfg

修改zoo.cfg配置文件，如下

 #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=/use/local/apache-zookeeper/data
 dataLogDir=/use/local/apache-zookeeper/logs
 #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
 #
 #he 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

输入命令vi /erc/profile配置环境变量，在文件末尾加上

 export ZOOKEEPER_HOME=/usr/local/apache-zookeeper
 export PATH=$PATH:$ZOOKEEPER_HOME/bin

输入命令source /etc/profile 让环境变量生效

进入 apache-zookeeper/bin目录下，输入命令 ./zkServer.sh start启动zk，./zkServer.sh stop停止服务，./zkServer.sh status查看状态
