其中:
2888端口號是zookeeper服務之間通信的端口。
3888是zookeeper與其他應用程序通信的端口。
然後，在dataDir=/home/zookeeper-3.4.12/data 下創建myid文件(編輯myid文件，並在對應的IP的機器上輸入對應的編號。例如：在安裝zookeeper機器上，myid 文件內容就是1。如果只在單點上進行安裝配置，那麼只有一個server.1)
[yuki@myhost ~]$ cd /home/zookeeper-3.4.12/data/
[yuki@myhost data]$ sudo vi myid
[xzds@DSCQ-BID29 data]$ cat myid

[yuki@myhost data]$ sudo vi /etc/profile

[yuki@myhost data]$ source /etc/profile
[yuki@myhost data]$ echo $ZOOKEEPER_HOME

2.1 編寫zookeeper啓動腳本

[yuki@myhost init.d]$ ll

###編寫啓動腳本
[yuki@myhost init.d]$ sudo vi zookeeper
#!/bin/bash
#chkconfig:2345 20 90
#description:zookeeper
#processname:zookeeper
source /etc/profile
#export JAVA_HOME=/home/yuki/JDK_HOME/jdk1.8.0_131
#export PATH=$JAVA_HOME/bin:$PATH
#define variables
zookeeper_start_file="/home/zookeeper-3.4.12/bin/zkServer.sh"
case $1 in
start)
sudo ${zookeeper_start_file} start
;;
stop)
sudo ${zookeeper_start_file} stop
;;
status)
sudo ${zookeeper_start_file} status
;;
restart)
sudo ${zookeeper_start_file} restart
;;
*) echo "require start|stop|status|restart"
;;
esac
然後，我們就可以下面的命令來啓動或者停止zookeeper服務了
[yuki@myhost init.d]$ /etc/init.d/zookeeper start 或者service zookeeper start
ZooKeeper JMX enabled by default
Using config: /home/zookeeper-3.4.12/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
2.2 設置zookeeper開機自啓動
[yuki@myhost init.d]$ sudo chkconfig zookeeper on
[yuki@myhost init.d]$ echo $?
0
[yuki@myhost init.d]$ sudo chkconfig --add zookeeper
[yuki@myhost init.d]$ sudo chkconfig --list
