Zookeeper 集群安装及监控

1. 前言

业务需要对Zookeeper集群进行监控，发现的方案有三种：

• JMX
• zookeeper exporter
• ZK Monitor(Since 3.6.0)

采用JMX 进行监控，可获取到的指标项不够丰富。Zookeeper Exporter监控可获得的指标项亦不太够丰富。从3.6.0之后，Zookeeper自带的Monitor结合Prometheus、Grafana可绘制出丰富的监控图表项。

2.下载并安装

• 下载并安装

# 下载
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.8.0/apache-zookeeper-3.8.0-bin.tar.gz --no-check-certificate
# 安装
tar -zxvf pache-zookeeper-3.8.0-bin.tar.gz -C /opt

• 创建data目录并myid

mkdir data
echo 1 >> myid

• 修改zk配置文件

cp zoo_sample.cfg zoo.cfg
vi zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/apache-zookeeper-3.8.0-bin/data
clientPort=2181
maxClientCnxns=1200
autopurge.snapRetainCount=10
autopurge.purgeInterval=24

server.1=192.168.2.53:2888:3888
server.2=192.168.2.35:2888:3888
server.3=192.168.2.45:2888:3888
# metrics
metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
metricsProvider.httpHost=0.0.0.0
metricsProvider.httpPort=7000
metricsProvider.exportJvmInfo=true

• 分发安装包并修改myid

scp -r /opt/apache-zookeeper-3.8.0-bin root@slave1:/opt
scp -r /opt/apache-zookeeper-3.8.0-bin root@slave2:/opt

echo 2 >> myid
echo 3 >> myid

3.启动

# 集群中每个机器逐个启动
zkServer.sh start
# 查看
zkServer.sh status

访问metrics地址: http://192.168.2.53:7000/metrics

4.接入Prometheus

# prometheus.yml

- job_name: ZOOKEEPER-QuarumPeermain
  static_configs:
  - targets: [\'master:7000\',\'slave1:7000\',\'slave2:7000\']

重启prometheus

systemctl restart prometheus

5. 接入Grafana

点击import，载入模板10465
