服务器单台:4C8G
官网下载地址:

https://www.apache.org/dyn/closer.lua/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz

关闭selinux

sed -i '7s#enforcing#disabled#g' /etc/selinux/config
setenforce 0

关闭防火墙

systemctl disable firewalld.service
systemctl stop firewalld.service

优化下载源

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

安装所需软件包

yum install wget vim -y

下载zookeeper

wget https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz

解压到/usr/local下

tar xf apache-zookeeper-3.6.1-bin.tar.gz -C /usr/local/

下载Java

网址:https://www.oracle.com/java/technologies/javase-jdk14-downloads.html
wget https://download.oracle.com/otn-pub/java/jdk/14.0.1+7/664493ef4a6946b186ff29eb326336a2/jdk-14.0.1_linux-x64_bin.tar.gz?AuthParam=1592647377_1b13524ed11ea1e651cf2709e0d61ce2

下载的文件有点…

[root@localhost ~]# ls
anaconda-ks.cfg  apache-zookeeper-3.6.1-bin.tar.gz  jdk-14.0.1_linux-x64_bin.tar.gz?AuthParam=1592647377_1b13524ed11ea1e651cf2709e0d61ce2

重命名下凑合能用

mv jdk-14.0.1_linux-x64_bin.tar.gz\?AuthParam\=1592647377_1b13524ed11ea1e651cf2709e0d61ce2 jdk-14.0.1_linux-x64_bin.tar.gz

解压

tar xf jdk-14.0.1_linux-x64_bin.tar.gz -C /usr/local/

添加环境变量

vim /etc/profile
文件末尾加入(JAVA_HOME则为java解压的目录)
# java
export JAVA_HOME=/usr/local/jdk-14.0.1
export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
export PATH=$PATH:${JAVA_HOME}/bin

source /etc/profile
# 执行命令检查
[root@localhost local]# java -version
java version "14.0.1" 2020-04-14
Java(TM) SE Runtime Environment (build 14.0.1+7)
Java HotSpot(TM) 64-Bit Server VM (build 14.0.1+7, mixed mode, sharing)

安装Java完成
修改zookeeper配置

cd /usr/local/apache-zookeeper-3.6.1-bin/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg
# 文件末尾加入:
server.1=localhost:2888:3888
# localhost可改为本机IP
cd ..
./bin/zkServer.sh start

检查是否启动

[root@localhost apache-zookeeper-3.6.1-bin]# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/apache-zookeeper-3.6.1-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone

添加环境变量

[root@localhost conf]# vim /etc/profile
#追加
# zookeeper
export ZK_HOME=/usr/local/apache-zookeeper-3.6.1-bin
export PATH=$PATH:${ZK_HOME}/bin

[root@localhost conf]# source /etc/profile
# 检查状态 如下则启动成功
[root@localhost conf]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/apache-zookeeper-3.6.1-bin/bin/../conf/zoo.cfg
