|NO.Z.00065|——————————|^^ 配置 ^^|——|Hadoop&实时数仓.V05|——|可视化.v05|监控：Flink配置.V5|

一、修改flink配置，开放flink被监控端口

### --- 把prometheus的jar包复制到flink的lib目录下

~~~     # 把prometheus的jar包复制到flink的lib目录下
~~~     # prometheus的jar包的地址在flink的plugin目录下：/opt/yanqi/servers/flink-1.11.1/plugins/metrics-prometheus/flink-metrics-prometheus-1.11.1.jar
[root@hadoop01 ~]# cp /opt/yanqi/servers/flink-1.11.1/plugins/metrics-prometheus/flink-metrics-prometheus-1.11.1.jar \
/opt/yanqi/servers/flink-1.11.1/lib/

### --- 修改flink-conf.yaml:

~~~     # 修改flink-conf.yaml配置文件
[root@hadoop01 ~]# vim /opt/yanqi/servers/flink-1.11.1/conf/flink-conf.yaml
~~~文件末尾添加如下参数：hadoop00：为prometheus，pushgateway机器的主机名
metrics.reporter.promgateway.class: org.apache.flink.metrics.prometheus.PrometheusPushGatewayReporter
metrics.reporter.promgateway.host: hadoop00
metrics.reporter.promgateway.port: 9091
metrics.reporter.promgateway.jobName: myJob
metrics.reporter.promgateway.randomJobNameSuffix: true
metrics.reporter.promgateway.deleteOnShutdown: false

### --- 发送配置文件到其它主机

~~~     # 发送prometheus.jar包到其它主机
[root@hadoop01 ~]# rsync-script /opt/yanqi/servers/flink-1.11.1/lib/flink-metrics-prometheus-1.11.1.jar
~~~     # 同步flink-conf.yaml配置文件到其它主机
[root@hadoop01 ~]# rsync-script /opt/yanqi/servers/flink-1.11.1/conf/flink-conf.yaml

二、启动flink.standalone集群模式

### --- 启动flink.standalone集群模式

~~~     # 启动flink.tandalone集群模式：启动hdfs和yarn服务
[root@hadoop01 ~]# /opt/yanqi/servers/flink-1.11.1/bin/start-cluster.sh

~~~     # 启动写入窗口

[root@hadoop01 ~]# nc -lp 7777
 ~~~写入参数
 hello prometheus

~~~     # 启动yarn session
[root@hadoop01 ~]# /opt/yanqi/servers/flink-1.11.1/bin/yarn-session.sh -s 1 -jm 1024 -tm 1024m
~~~输出参数
[] - Submitting application master application_1638345082205_0001
JobManager Web Interface: http://hadoop03:42033

~~~     # 启动flink.yarn.jobs
[root@hadoop01 ~]# /opt/yanqi/servers/flink-1.11.1/bin/flink run \
-c WordCountScalaStream -yid application_1638345082205_0001 /root/myjars/FirstFlink-1.0-SNAPSHOT.jar
 ~~~输出参数
Job has been submitted with JobID 391c28db1d8a2303234373b4f1de8e9f

 二、查看Pushgateway是否监控到数据
