zookeeper安装  参考：https://www.cnblogs.com/shaozm/p/10141727.html

下载 ： 

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz

cd zookeeper-3.4.14
mkdir data
cd conf
mv zoo_sample.cfg  zoo.cfg
vi zoo.cfg

配置如下：

# 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=/home/hadoop/zookeeper-3.4.14/data
dataLogDir=/home/hadoop/zookeeper-3.4.14/log
# 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
server.1=192.168.91.112:2888:3888
server.2=192.168.91.113:2888:3888
server.3=192.168.91.114:2888:3888
#
# 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

 

备注： server.1 server.2 server.3   是指三台机器

以下两个目录手工创建
dataDir=/home/hadoop/zookeeper-3.4.14/data
dataLogDir=/home/hadoop/zookeeper-3.4.14/log

conf目录下创建java.env
vi

java.env

export JVMFLAGS="-Xms100m -Xmx300m $JVMFLAGS"

设置每台zoomkeeper 的 id

echo "1" > /home/hadoop/zookeeper-3.4.14/data/myid

做好以上配置 之后将整个zookeeper的目录远程拷贝的其他两台机器上
  scp -r /home/hadoop/zookeeper-3.4.14 hadoop@slave1:/home/hadoop/
  scp -r /home/haddop/zookeeper-3.4.14 hadoop@slave2:/home/hadoop/
并 修改 data/myid 中的内容为  2 （server 2）或 3（seerver 3）

启动 命令 
  
zookeeper-3.4.14/bin/zkServer.sh start   日志会在启动目录下 生成 zookeeper.out

查看状态命令
zookeeper-3.4.14/bin/zkServer.sh status
