Cloudflared A : 192.168.11.4/24 , Cloudflared B : 192.168.11.7/24 , Cloudflared C : 192.168.11.9/24 * 安裝程序如同上一步驟, Token 都相同 ==== 4. 確認 Cloudflare Tunnel 狀態 ==== * Networks -> Tunnels -> <Tunnel 名稱> -> View all connectors \\ {{:tech:螢幕擷取畫面_2025-04-03_192225.png|}} \\ {{:tech:螢幕擷取畫面_2025-04-03_192321.png|}} * 看到安裝的三個 Cloudflared 都正常出現 ==== 5. 設定網站對應 ==== * 這步驟類似 Nginx Proxy Manager(Reverse Proxy)設定網站對應 * Networks -> Tunnels -> <Tunnel 名稱> -> Edit -> Public Hostname -> Add a public hostname \\ {{:tech:螢幕擷取畫面_2025-04-03_192725.png|}} \\ {{:tech:螢幕擷取畫面_2025-04-03_192819.png|}} * 新增一個網站 Exp. www.ichiayi.com -> http://192.168.11.233 \\ {{:tech:螢幕擷取畫面_2025-04-03_193527.png|}} <note important> - 新增一個網站會在 Cloudflare 該網域的 DNS 建立一筆 CNAME 紀錄, 如果 DNS 已經有一筆 A 或衝突的紀錄, 就會新增失敗, 需要回到 DNS 管理將衝突的紀錄先刪除 - 要先到 Cloudflared 內驗證要 Forward 的網址 Exp. http://192.168.11.233 是否可以正常存取 - 如果新增成功, 可以查看網站的紀錄 Exp. access.log 可以看到流量會由三台 Cloudflared 隨機進入 <cli> : 192.168.11.4 - - [03/Apr/2025:19:25:24 +0800] "GET / HTTP/1.1" 200 36257 "-" "check_http/v (monitoring-plugins 2.4.0)" 192.168.11.4 - - [03/Apr/2025:19:30:23 +0800] "GET / HTTP/1.1" 200 36257 "-" "check_http/v (monitoring-plugins 2.4.0)" 192.168.11.9 - - [03/Apr/2025:19:35:18 +0800] "GET /modules/tadnews/pda.php?op=news&nsn=13&ncsn=5 HTTP/1.1" 200 2705 "-" "Mozilla/5.0 (compatible; AhrefsBot/7.0; +http://ahrefs.com/robot/)" 192.168.11.7 - - [03/Apr/2025:19:35:24 +0800] "GET / HTTP/1.1" 200 36257 "-" "check_http/v (monitoring-plugins 2.4.0)" 192.168.11.4 - - [03/Apr/2025:19:40:25 +0800] "GET / HTTP/1.1" 200 36257 "-" "check_http/v (monitoring-plugins 2.4.0)" 192.168.11.9 - - [03/Apr/2025:19:43:57 +0800] "GET / HTTP/1.1" 200 36259 "-" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.4 - - [03/Apr/2025:19:43:58 +0800] "GET / HTTP/1.1" 200 36259 "-" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.9 - - [03/Apr/2025:19:44:01 +0800] "GET / HTTP/1.1" 200 36259 "-" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.4 - - [03/Apr/2025:19:44:16 +0800] "GET / HTTP/1.1" 200 36259 "-" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.4 - - [03/Apr/2025:19:44:19 +0800] "GET / HTTP/1.1" 200 36259 "-" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.4 - - [03/Apr/2025:19:44:31 +0800] "GET /modules/tadnews/page.php?nsn=86 HTTP/1.1" 200 25365 "-" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.7 - - [03/Apr/2025:19:44:32 +0800] "GET /modules/tadnews/css/module.css HTTP/1.1" 200 4967 "https://lin.ichiayi.com/modules/tadnews/page.php?nsn=86" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" 192.168.11.4 - - [03/Apr/2025:19:44:32 +0800] "GET /modules/tadtools/css/iconize.css HTTP/1.1" 200 6483 "https://lin.ichiayi.com/modules/tadnews/page.php?nsn=86" "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Mobile Safari/537.36" : </cli> </note> ===== 參考網址 ===== * https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/ {{tag>proxy nginx tunnel}} tech/cloudflare_tunnel.txt 上一次變更: 2025/04/03 19:51由 jonathan
