Synology 使用Docker架設LibreNMS

運行環境
  • DSM 7.2
安裝LibreNMS

確認已安裝Portainer，在docker內新增資料夾librenms並且在裡面分別新增data、db、redis資料夾

修改資料夾權限使docker能夠寫入執行

chmod 755 /volume1/docker/librenms -R

進入Portainer，點選堆棧(Stack)，並添加堆棧

名稱填寫librenms，並貼到編輯器中，指令內PUID和PGID於Shell內執行id並自行替換

user1@synology:~$ id
uid=1026(user1) gid=100(users)

部屬堆棧

image.png

成功後右上角應會顯示堆棧部署成功

等待幾分鐘安裝，確認所有服務已經執行

image.png

輸入IP和設定的PORT，例如http://Synology IP:28083，進入LibreNMS 安裝頁面

image.png

建立管理員後完成安裝

image.png

若出現419 Page Expired先清除快取

點選LibreNMS容器並進入終端

image.png

image.png

php artisan config:clear
php artisan cache:clear
php artisan route:clear
php artisan view:clear

重新整理網頁後再次登入

若輸入網址後直接跳過安裝頁面到登入畫面請手動新增使用者

點選LibreNMS容器並進入終端新增使用者

image.png

image.png

lnms user:add --role=admin user1

重新整理網頁後再次登入

進行組態驗證確認無錯誤設定，若有依照建議修正

image.png

開始監控Synology設備

開啟SNMP功能

image.png

LibreNMS新增Synology設備，輸入IP和community
