安裝 Nginx Agent 的方式

• 返回 Ubuntu 20.04 / CentOS7 安裝 LibreNMS 程序

• 這是 SNMP Extend

• 設定啟動 Nginx 的狀態頁面

  vi /etc/nginx/conf.d/default.conf 

  :
  location /nginx-status {
      stub_status on;
      access_log   off;
      allow 127.0.0.1;
      allow ::1;
      deny all;
  }
  :

  重新啟動 nginx

  systemctl restart nginx

• 檢查讀取 nginx 狀態頁面

  curl http://localhost/nginx-status

  正確結果會類似以下訊息<xtermrtf>

Active connections: 8 server accepts handled requests 10 10 10 Reading: 0 Writing: 1 Waiting: 7 </xtermrtf>

• 至 Nginx 主機內安裝

  wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/nginx -O /etc/snmp/nginx
  chmod +x /etc/snmp/nginx

• 確認 nginx可以正確執行

  /etc/snmp/nginx

  如果正確執行應該可以看到類似的訊息<xtermrtf>

10 0 1 9 38 </xtermrtf>

• 修改 snmpd 設定

  vi /etc/snmp/snmpd.conf

  :
  extend nginx /etc/snmp/nginx

  重新啟動 snmpd

  systemctl restart snmpd
