# 快速上手指南
|
||
|
||
5 分鐘內開始操作 PVECluster。
|
||
|
||
## 前置條件
|
||
|
||
- 可連線至 `192.168.42.0/24` 網段
|
||
- 已安裝 `curl` 和 `python3`（用於解析 JSON）
|
||
|
||
## 1. 確認連線
|
||
|
||
```bash
|
||
# SSH（三台任一皆可）
|
||
ssh 192.168.42.38 "pveversion"
|
||
# 預期輸出：pve-manager/8.4.14/...
|
||
|
||
# API
|
||
curl -sk https://192.168.42.38:8006/api2/json/version \
|
||
-H "Authorization: PVEAPIToken=root@pam!claude=fefcffca-df6e-48de-8adf-7907cd2ea879"
|
||
# 預期輸出：{"data":{"version":"8.4.14",...}}
|
||
```
|
||
|
||
## 2. 設定環境變數（方便後續操作）
|
||
|
||
```bash
|
||
export PVE_HOST="https://192.168.42.38:8006/api2/json"
|
||
export PVE_AUTH="Authorization: PVEAPIToken=root@pam!claude=fefcffca-df6e-48de-8adf-7907cd2ea879"
|
||
|
||
# 定義快捷函式
|
||
pve-get() { curl -sk "$PVE_HOST$1" -H "$PVE_AUTH"; }
|
||
pve-post() { curl -sk -X POST "$PVE_HOST$1" -H "$PVE_AUTH" "${@:2}"; }
|
||
```
|
||
|
||
## 3. 查看叢集狀態
|
||
|
||
```bash
|
||
# 節點概覽
|
||
pve-get /nodes | python3 -m json.tool
|
||
|
||
# 所有 VM/容器
|
||
pve-get /cluster/resources?type=vm | python3 -c "
|
||
import sys, json
|
||
data = json.load(sys.stdin)['data']
|
||
data.sort(key=lambda x: x['vmid'])
|
||
print(f\"{'VMID':<6} {'Type':<5} {'Status':<9} {'Node':<8} {'Name':<12} {'CPU':>4} {'Mem':>8}\")
|
||
print('-' * 60)
|
||
for d in data:
|
||
mem = f\"{d['mem'] // 1048576}M\" if d['mem'] else '-'
|
||
print(f\"{d['vmid']:<6} {d['type']:<5} {d['status']:<9} {d['node']:<8} {d['name']:<12} {d.get('maxcpu','?'):>4} {mem:>8}\")
|
||
"
|
||
```
|
||
|
||
## 4. 常用操作範例
|
||
|
||
### 啟動 / 停止容器
|
||
|
||
```bash
|
||
# 啟動 CT103（N8N）
|
||
pve-post /nodes/pve/lxc/103/status/start
|
||
|
||
# 優雅關閉 CT103
|
||
pve-post /nodes/pve/lxc/103/status/shutdown
|
||
|
||
# 強制停止
|
||
pve-post /nodes/pve/lxc/103/status/stop
|
||
```
|
||
|
||
### 啟動 / 停止 VM
|
||
|
||
```bash
|
||
# 啟動 VM 120（K3s Worker）
|
||
pve-post /nodes/pve-02/qemu/120/status/start
|
||
|
||
# 關閉 VM
|
||
pve-post /nodes/pve-02/qemu/120/status/shutdown
|
||
```
|
||
|
||
### 查看單一 VM/容器狀態
|
||
|
||
```bash
|
||
# CT 狀態
|
||
pve-get /nodes/pve/lxc/102/status/current | python3 -m json.tool
|
||
|
||
# VM 狀態
|
||
pve-get /nodes/pve/qemu/110/status/current | python3 -m json.tool
|
||
```
|
||
|
||
### 查看 / 修改設定
|
||
|
||
```bash
|
||
# 查看 CT102 設定
|
||
pve-get /nodes/pve/lxc/102/config | python3 -m json.tool
|
||
|
||
# 透過 SSH 修改記憶體（改為 1GB）
|
||
ssh 192.168.42.38 "pvesh set /nodes/pve/lxc/102/config --memory 1024"
|
||
```
|
||
|
||
### 儲存使用狀況
|
||
|
||
```bash
|
||
pve-get /cluster/resources?type=storage | python3 -c "
|
||
import sys, json
|
||
data = json.load(sys.stdin)['data']
|
||
seen = set()
|
||
print(f\"{'Storage':<20} {'Type':<8} {'Shared':<7} {'Used':>10} {'Total':>10} {'Usage':>6}\")
|
||
print('-' * 65)
|
||
for d in sorted(data, key=lambda x: x['storage']):
|
||
key = d['storage']
|
||
if key in seen: continue
|
||
seen.add(key)
|
||
total = d.get('maxdisk', 0)
|
||
used = d.get('disk', 0)
|
||
pct = f\"{used/total*100:.0f}%\" if total else '-'
|
||
print(f\"{key:<20} {d['plugintype']:<8} {'yes' if d.get('shared') else 'no':<7} {used//1073741824:>8} GB {total//1073741824:>8} GB {pct:>6}\")
|
||
"
|
||
```
|
||
|
||
### 立即備份
|
||
|
||
```bash
|
||
# 備份 CT115 到 PBS
|
||
pve-post /nodes/pve-02/vzdump \
|
||
-d "vmid=115" \
|
||
-d "storage=pbs" \
|
||
-d "mode=snapshot" \
|
||
-d "notes-template={{guestname}}"
|
||
```
|
||
|
||
### 建立快照
|
||
|
||
```bash
|
||
# CT 快照
|
||
pve-post /nodes/pve/lxc/102/snapshot \
|
||
-d "snapname=before-upgrade" \
|
||
-d "description=升級前快照"
|
||
|
||
# 列出快照
|
||
pve-get /nodes/pve/lxc/102/snapshot | python3 -m json.tool
|
||
```
|
||
|
||
## 5. 節點與 VMID 對照速查
|
||
|
||
操作 API 需要知道目標在哪個節點上：
|
||
|
||
| VMID | 節點 | 類型 | 用途 |
|
||
|---|---|---|---|
|
||
| 100-101, 107, 109, 115, 117 | pve-02 | lxc | SSH Jump, Headscale, MailPit, PDF, Lydia |
|
||
| 102-105, 116, 119, 125, 126 | pve | lxc | Tailscale, N8N, Caddy, MyIP, Bark, Gotify, Ubuntu |
|
||
| 108, 112, 114, 118, 124 | pve-03 | lxc | Python, OpenClaw, Podman, PG, NPM+Keycloak |
|
||
| 110, 121 | pve | qemu | OpenWRT, K3s |
|
||
| 111, 120 | pve-02 | qemu | PBS, K3s |
|
||
| 122 | pve-03 | qemu | K3s |
|
||
|
||
> 不確定在哪個節點？用 `/cluster/resources?type=vm` 查詢即可。
|
||
|
||
## 6. Web UI
|
||
|
||
瀏覽器開啟 `https://192.168.42.38:8006`，使用 `root` / PAM 認證登入。
|
||
三個節點任一 IP 皆可進入同一管理介面。
