zookeeper安装部署(单节点)

环境:

OS:Centos 7

zookeeper:3.8.4

 

1.获取安装介质

https://zookeeper.apache.org/releases.html#download

 下载稳定版本

 

 

wget https://dlcdn.apache.org/zookeeper/zookeeper-3.8.4/apache-zookeeper-3.8.4-bin.tar.gz

 

2.安装
[root@node1 /]# cd /soft
[root@node1 soft]# tar -xvf apache-zookeeper-3.8.4-bin.tar.gz
[root@node1 soft]# mv apache-zookeeper-3.8.4-bin /opt/zookeeper-3.8.4

 

3.创建数据目录

[root@node1 zookeeper-3.8.4]# cd /opt/zookeeper-3.8.4
[root@node1 zookeeper-3.8.4]# mkdir data

 

4.准备配置文件zoo.cfg

进入zookeeper的conf目录，拷贝zoo_sample.cfg为zoo.cfg，cp zoo_sample.cfg zoo.cfg 修改zoo.cfg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=/opt/zookeeper-3.8.4/data
# the port at which the clients will connect
clientPort=2181
# 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.
#
# https://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

## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpHost=0.0.0.0
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

只修改红色的地方,其他地方保持不变

 

5.启动zookeeper

进入zookeeper的bin目录,启动zookeeper服务,每个节点都需要启动
[root@localhost bin]# cd /opt/zookeeper-3.8.4/bin
[root@node1 bin]# ./zkServer.sh start
/bin/java
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.8.4/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

 

6.查看端口
[root@node1 conf]# ss -nlp|grep 2181
tcp LISTEN 0 50 [::]:2181 [::]:* users:(("java",pid=28312,fd=59))

 

7.查看状态
[root@node1 bin]# ./zkServer.sh status
/bin/java
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.8.4/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: standalone

 

8.连接zookeeper
[root@localhost bin]# ./zkCli.sh -server localhost:2181
[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper]
