CentOS 7 安装 Zookeeper

1、解压并修改配置文件

$ mkdir -p /usr/java
$ cd /usr/java

使用ftp工具把安装包放到java目录下，解压

$ tar -zxvf zookeeper-3.4.13.tar.gz

$ mv zookeeper-3.4.13 zookeeper

$ mkdir ./zookeeper/data

$ mkdir ./zookeeper/logs

$ cp ./zookeeper/conf/zoo_sample.cfg ./zookeeper/conf/zoo.cfg

$ vi ./zookeeper/conf/zoo.cfg

dataDir=/usr/java/zookeeper/data
dataLogDir=/usr/java/zookeeper/logs

server.1=centos-100:2888:3888

$ touch ./zookeeper/data/myid

$ echo "1" > ./zookeeper/data/myid

2、配置环境变量

$ vi /etc/profile

# Zookeeper Env
export ZOOKEEPER_HOME=/usr/java/zookeeper
export PATH=$ZOOKEEPER_HOME/bin:$PATH

$ source /etc/profile

3、开放防火墙

添加：$ sudo firewall-cmd --zone=public --add-port=2181/tcp --permanent
$ sudo firewall-cmd --zone=public --add-port=2888/tcp --permanent
$ sudo firewall-cmd --zone=public --add-port=3888/tcp --permanent
重启：$ sudo firewall-cmd --reload
查看：$ firewall-cmd --zone=public --list-port

4、添加到服务

$ cd /etc/init.d

$ touch zookeeper

$ chmod 755 zookeeper

$ vi zookeeper

#!/bin/sh
# chkconfig: 2345 20 90
# Description: zookeeper
# processname: zookeeper

export JAVA_HOME=/usr/java/jdk

case $1 in
    start)
                su root /usr/java/zookeeper/bin/zkServer.sh start
    ;;
    stop)
                su root /usr/java/zookeeper/bin/zkServer.sh stop
    ;;
    status)
                su root /usr/java/zookeeper/bin/zkServer.sh status
    ;;
    restart)
                su root /usr/java/zookeeper/bin/zkServer.sh restart
    ;;
    *)
                echo "require start|stop|status|restart"  
    ;;
esac

chmod 755 zookeeper

$ chkconfig zookeeper on

$ chkconfig --list
