zookeeper单机版安装

1、安装jdk（提前安装准备）

复制代码

[root@keep-hadoop ~]# java -version
java version "1.8.0_172"
Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)

2、下载安装包

https://downloads.apache.org/zookeeper/

3、解压安装包到指定目录

复制代码

[root@keep-hadoop ~]# tar -zxvf zookeeper-3.4.10.tar.gz -C /usr/local/src

4、配置环境变量

复制代码

[root@keep-hadoop ~]# vim /etc/profile
export ZOOKEEPER_HOME=/usr/local/src/zookeeper-3.4.10
export PATH=$PATH:$ZOOKEEPER_HOME/bin

[root@keep-hadoop ~]# source /etc/profile

5、配置Zookeeper目录

复制代码

[root@keep-hadoop ~]# cd $ZOOKEEPER_HOME
[root@keep-hadoop zookeeper-3.4.10]# mkdir data
[root@keep-hadoop zookeeper-3.4.10]# mkdir logs

6、创建myid文件

复制代码

[root@keep-hadoop data]# echo 1 > myid
[root@keep-hadoop data]# cat myid
1

7、复制模板配置文件，生成配置文件

复制代码

[root@keep-hadoop zookeeper-3.4.10]# cd conf/
[root@keep-hadoop conf]# cp zoo_sample.cfg zoo.cfg
[root@keep-hadoop conf]# vim zoo.cfg
# 添加内容
dataDir=/usr/local/src/zookeeper-3.4.10/data
dataLogDir=/usr/local/src/zookeeper-3.4.10/logs
server.1=192.168.140.130:2888:3888

8、启动Zookeeper

复制代码

[root@keep-hadoop zookeeper-3.4.10]# cd bin/
[root@keep-hadoop bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@keep-hadoop bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: standalone

9、使用java的jps检测进程

复制代码

# jps看到QuorumPeerMain进程就已经启动成功了
[root@keep-hadoop bin]# jps
13874 QuorumPeerMain
14073 Jps

10、停止Zookeeper

复制代码

[root@keep-hadoop bin]# ./zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper-3.4.10/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
[root@keep-hadoop bin]# jps
14444 Jps
