本文详细介绍如何在Linux环境下安装和配置ZooKeeper集群，包括环境变量配置、防火墙设置及服务管理等步骤。

安装zookeeper

zookeeper-3.4.11下载地址

在/usr/local目录中新建一个zookeeper目录

mkdir zookeeper

将zookeeper-3.4.11.tar.gz移动到zookeeper，解压

tar -zxvf zookeeper-3.4.11.tar.gz

*在/usr/local/zookeeper/zookeeper-3.4.11中新建一下目录

mkdir data
mkdir logs

把zookeeper-3.4.11/conf目录中zoo_sample.cfg拷贝为zoo.cfg

cp zoo_sample.cfg zoo.cfg

修改zoo.cfg配置文件

# 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/zookeeper/zookeeper-3.4.11/data
dataLogDir=/usr/local/zookeeper/zookeeper-3.4.11/logs
# the port at which the clients will connect
clientPort=2181
#ip填写注册中心服务器
server.1=ip:2888:3888
# 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

在/usr/local/zookeeper/zookeeper-3.4.11/data创建myid文件

vim myid
内容填写：1

配置环境变量

# 打开环境配置
vim /etc/profile

# zookeeper
export ZOOKEEPER_HOME=/usr/local/zookeeper/zookeeper-3.4.11
export PATH=$ZOOKEEPER_HOME/bin:$PATH

# 生效配置
source /etc/profile

配置防火墙

centos7没有iptables防火墙文件 
1、首先要停止 firewalld 服务，输入下面的命令：
systemctl stop firewalld.service 
然后要禁止 firewalld 服务在系统启动的时候自动启动， 输入下面的命令：
2、systemctl disable firewalld.server
如果卸载：
yum remove firewalld -y
3、CentOS 7 安装 iptables 防火墙 
安装iptables 包
yum install iptables-services
4、设置iptables 防火墙服务开机自动启动
systemctl enable iptables
5、开启服务
systemctl start iptables.service
6、重启防火墙使配置生效
systemctl restart iptables.service
7、检查是否安装了iptables
service iptables status 
8、编辑iptables
vim /etc/sysconfig/iptables
然后增加：
-A INPUT -p tcp -m state --state NEW -m tcp --dport 2181 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 2888 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3888 -j ACCEPT

启用并测试zookeeper
在/usr/local/zookeeper/zookeeper-3.4.11/bin中

启动
zkServer.sh start
重启
zkServer.sh restart
停止
zkServer.sh start
查看状态
zkServer.sh status

·输入命令查看进程

jps

·可以看到

15097 QuorumPeerMain
26383 Jps

·QuorumPeerMain是zookeeper进程，启动正常

查看zookeeper服务输入的日志：

cd /usr/local/zookeeper/zookeeper-3.4.11/bin
tail -f zookeeper.out

服务配置
cd /etc/init.d/目录下，创建zookeeper文件

#!/bin/bash
export JAVA_HOME=/usr/local/java/jdk1.8.0_162
export PATH=$JAVA_HOME/bin:$PATH

#chkconfig:2345 20 90
#description:zookeeper
#processname:zookeeper
case $1 in
          start) su root /usr/local/zookeeper/zookeeper-3.4.11/bin/zkServer.sh start;;
          stop) su root /usr/local/zookeeper/zookeeper-3.4.11/bin/zkServer.sh stop;;
          status) su root /usr/local/zookeeper/zookeeper-3.4.11/bin/zkServer.sh status;;
          restart) su root /usr/local/zookeeper/zookeeper-3.4.11/bin/zkServer.sh restart;;
          *)  echo "require start|stop|status|restart"  ;;
