ckman安装步骤

安装zookeeper集群

          

          zk的版本不能低于3.6

          配置普通用户sudo    vi /etc/sudoers

         

          

          zookeeper的配置文件需要开启配置metrics上报

          

metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
metricsProvider.httpPort=7000
metricsProvider.exportJvmInfo=true
admin.enableServer=true
admin.serverPort=8080

  测试zookeeper安装结果

        http://192.168.30.101:8080/commands/mntr

        

安装prometheus

            下载源码包    https://github.com/prometheus/prometheus/releases/

             nohup ./prometheus --storage.tsdb.retention.time=15d &

           

下载clikhouse server安装包

          https://repo.yandex.ru/clickhouse/rpm/lts/x86_64/

          

        下载三个rpm包

        

 安装ck集群

       上传rpm包到ckmanager

       

       

     

   部署设置

        所有节点的防火墙必须关闭,各个节点之间通过9000端口进行连通检查

        

         

        

        

      

部署问题排查

        ckman日志查询

              tail -f /home/admin/ckman/src/ck/ckman/logs/ckman.log

        每个节点上都有这个日志文件

              tail -f /var/log/clickhouse-server/clickhouse-server.log

       

      客户端连接ck集群测试

        clickhouse-client -m -u default --password 123456

        

ckman配置promethues监控

      1.下载node_exporter压缩包

          https://github.com/prometheus/node_exporter/releases/

      2.安装到每个节点

      3.修改promethues配置文件

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]

  - job_name: "zk"
    static_configs:
      - targets: ["192.168.30.146:7000","192.168.30.101:7000","192.168.30.151:7000"]

  - job_name: "node"
    static_configs:
      - targets: ["192.168.30.146:9100","192.168.30.101:9100","192.168.30.151:9100","192.168.30.70:9100"]

  - job_name: "ck"
    static_configs:
      - targets: ["192.168.30.146:9363","192.168.30.101:9363","192.168.30.151:9363","192.168.30.70:9363"]

      4.修改ckman配置文件

server:
  port: 8808
  https: false
  #certfile:
  #keyfile:
  pprof: true
  session_timeout: 3600
  # support local, mysql, postgres
  persistent_policy: local
  task_interval: 5
  #public_key:

log:
  level: INFO
  max_count: 5
  # megabyte
  max_size: 10
  # day
  max_age: 10


prometheus:
  hosts:
    - 192.168.30.146:9090
  timeout: 10

# cron job task
cron:
  sync_logic_schema: "0 * * * * ?"

      5.重启ckman

      6.需要注意prometheus和node exporter版本匹配问题

      7.展示监控页面

         

 卸载重置ckman

        1.终止ckman

           

        2.终止每台shard上的clickhouse-server

           systemctl stop clickhouse-server
