| | ====== 安裝 PVE (Proxmox Virtual Environment) Agent 的方式 ====== |
| | |
| | * 返回 [[tech:librenms]] |
| | * 這是 SNMP Extend |
| | * PVE 8.2 |
| | |
| | ===== 設定程序 ===== |
| | * 在 PVE 主機內安裝 <code sh> |
| | apt install libpve-apiclient-perl sudo |
| | wget https://raw.githubusercontent.com/librenms/librenms-agent/master/agent-local/proxmox -O /usr/local/bin/proxmox |
| | chmod +x /usr/local/bin/proxmox |
| | </code>驗證是否 proxmox 可以執行成功<code sh> |
| | /usr/local/bin/proxmox</code>如果成功, 訊息大概如下<cli> |
| | <<<app-proxmox>>> |

| | 152/net0/94636075/77614449/pve-ms |
| | </cli> |
| | * 修改 sudo 設定檔<code h /etc/sudoers.d/proxmox> |
| | # Cmnd alias specification |
| | Debian-snmp ALL=(ALL) NOPASSWD: /usr/local/bin/proxmox |
| | </code> |
| | * 修改 snmpd 設定<code> |
| | vi /etc/snmp/snmpd.conf</code><file> |
| | : |
| | extend proxmox /usr/bin/sudo -S /usr/local/bin/proxmox |
| | </file>重新啟動 snmpd <code sh> |
| | systemctl restart snmpd |
| | </code> |
| | |
| | <note important> |
| | 如果 LibreNMS 無法正確呈現虛擬機網路流量圖, 出現 Error Drawing Graph 的訊息如下, 可能和 rrd 內 proxmox 目錄權限有關, 可以進入 LibreNMS 主機內執行 chown 修改目錄正確權限, Exp. 若正確權限應該為 librenms:librenms <code sh> |
| | chown -R librenms:librenms /opt/librenms/rrd/proxmox/</code> \\ {{:tech:librenms:2020071502.png}} \\ {{:tech:librenms:2020071501.png}} |
| | </note> |
| | |
| | |
| | ===== 以下 Agent 方式 ===== |
| | - 設定啟用 Proxmox graphs 服務 <code h /opt/librenms/config.php> |
| | : |
| | $config['enable_proxmox'] = 1; |
| | </code> |
| | - 到 PVE 主機內安裝 LibreNMS-agent <code sh> |
| | apt-get install sudo |
| | wget https://raw.githubusercontent.com/librenms/librenms-agent/master/agent-local/proxmox -O /usr/local/bin/proxmox |
| | chmod +x /usr/local/bin/proxmox</code><cli> |
| | root@nuc:~# wget https://raw.githubusercontent.com/librenms/librenms-agent/master/agent-local/proxmox -O /usr/local/bin/proxmox |
| | root@nuc:~# chmod +x /usr/local/bin/proxmox |
| | root@nuc:~# /usr/local/bin/proxmox |

| | - 到 PVE 主機內修改 sudo 與 snmpd 設定檔並重起 snmpd <code h /etc/sudoers> |
| | : |
| | # Cmnd alias specification |
| | Debian-snmp ALL=(ALL) NOPASSWD: /usr/local/bin/proxmox |

| | : |
| | extend proxmox /usr/bin/sudo /usr/local/bin/proxmox |
| | </code><code sh> |
| | systemctl restart snmpd |
| | </code> |
| | - 可以到 LibreNMS 主機內透過 snmpwalk 來驗證是否 PVE 主機內的 snmpd 設定正確 Exp.<code sh> |
| | snmpwalk -v2c -c public 192.168.11.251 NET-SNMP-EXTEND-MIB::nsExtendOutput2Table</code><cli> |
| | [root@ct-librenms ~]# snmpwalk -v2c -c public 192.168.11.251 NET-SNMP-EXTEND-MIB::nsExtendOutput2Table |
| | NET-SNMP-EXTEND-MIB::nsExtendOutLine."proxmox".1 = STRING: <<<app-proxmox>>> |

| | </cli> |
| | - 到 LibreNMS PVE 主機項目啟用 Application - Proxmox {{:tech:2019112201.png}} |
| | - 再來就可以在 PVE 主機項目看到 app 的分頁 {{:tech:2019112202.png}} |
