一、下载elasticsearch_exporter二进制文件压缩包

1、在节点上执行命令下载

wget "https://github.com/justwatchcom/elasticsearch_exporter/releases/download/v1.1.0/elasticsearch_exporter-1.1.0.linux-amd64.tar.gz"

2、解压压缩包

[root@master elasticsearch_exporter]# ls
elasticsearch_exporter-1.1.0.linux-amd64.tar.gz
[root@master elasticsearch_exporter]# tar -xvf elasticsearch_exporter-1.1.0.linux-amd64.tar.gz
[root@master elasticsearch_exporter]# ls
drwxr-xr-x 2       80 Aug  2  2022 elasticsearch_exporter-1.1.0.linux-amd64
-rw-r--r-- 1 10649117 Feb  3 15:04 elasticsearch_exporter-1.1.0.linux-amd64.tar.gz

二、将elasticsearch_exporter-1.1.0.linux-amd64目录下的 elasticsearch_exporter二进制文件复制到 /usr/local/bin路径下

[root@master elasticsearch_exporter]# cd elasticsearch_exporter-1.1.0.linux-amd64
[root@master elasticsearch_exporter]# ls
elasticsearch_exporter  LICENSE  NOTICE
[root@master elasticsearch_exporter]# cp elasticsearch_exporter /usr/local/bin/
[root@master elasticsearch_exporter]# ls -l /usr/local/bin/elasticsearch_exporter
-rwxr-xr-x 1 root root 20745692 Feb  3 15:09 /usr/local/bin/elasticsearch_exporter

三、创建systemd service文件

根据实际情況修改其中的Environment配置值
如果上一步骤沒有修改创建用户命令中的认证参数
则下文可不做变更
直接复制下文全部文字命令並在节点上执行即可

cat <<EOF > /etc/systemd/elasticsearch_exporter.service
[Unit]
Description=elasticsearch_exporter
After=local-fs.target network-online.target network.target
Wants=local-fs.target network-online.target network.target
 
[Service]
ExecStart=/usr/local/elasticsearch_exporter/elasticsearch_exporter \
  --es.all --es.indices \
  --es.cluster_settings \
  --es.indices_settings \
  --es.shards --es.snapshots \
  --web.listen-address ":9114" \
  --es.timeout 10s \
  --web.telemetry-path "/metrics" \
  --es.uri http://elastic:2wsxCDE#@10.82.42.196:9200
Restart=on-failure
[Install]
WantedBy=multi-user.target
EOF

四、重载系统systemd配置

执行命令：systemctl daemon-reload

五、启动服务并且设置服务自启

[root@master blackbox_exporter]# systemctl enable --now elasticsearch_exporter
Created symlink from /etc/systemd/system/multi-user.target.wants/elasticsearch_exporter.service to /etc/systemd/system/elasticsearch_exporter.service.

六、查看服务运行状态

执行命令
能夠得到类似下文的回显结果
主要看Active属性值
以及日志中提示：systemctl status elasticsearch_exporter

systemctl status elasticsearch_exporter
● elasticsearch_exporter.service - elasticsearch_exporter
   Loaded: loaded (/etc/systemd/system/elasticsearch_exporter.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2023-02-03 15:55:03 CST; 10s ago
 Main PID: 79681 (elasticsearch_exporter)
   CGroup: /system.slice/elasticsearch_exporter.service
           └─79681 /usr/local/bin/elasticsearch_exporter--config.file=/app/software/elasticsearch_exporter-1.1.0.linux-amd64/blackbox.yml --web.listen-address=:9114

七、测试接口

在节点上使用命令访问接口
能夠得到类似下文結果：curl -s {{节点IP}}:9114/metrics

[root@master ~]# curl -s 10.82.42.196:9114/metrics
......
......

或直接使用浏览器访问能夠看到相关 elasticsearch实例指标信息则为正常{{节点IP}}:9114/metrics

八、配置Prometheus的任务

cd /usr/local/prometheus
vim /usr/local/prometheus/prometheus.yml，如下：

  - job_name: 'elasticsearch'
    scrape_interval: 60s
    scrape_timeout:  30s
    static_configs:
    - targets:
           - 10.82.42.196:9114

重新启动Prometheus：文章来源地址https://www.toymoban.com/news/detail-643515.html
