反向代理404

⑴ nginx反向代理nodejs伺服器不成功

通過9009和9008埠訪問得到結果一致

判斷應該是node伺服器沒有 /x/y目錄，所以404了

⑵ 電腦桌面上出現404 found nginx 好幾個月了怎麼辦 急急急急！

1、Nginx ("engine x") 是一個高性能的 HTTP 和 反向代理 伺服器，也是一個 IMAP/POP3/SMTP 代理伺服器。
這個錯誤顯然是你的機器安裝了這個軟體，配置錯誤導致提示。
2、另一個情況，是你訪問一個配置這個服務的網站，需要刪除這個鏈接。

⑶ 菜鳥關於.htaccess的一些問題。反向代理。（追加分數）

.htaccess是控制偽靜態規則的一個文件，具體要看你的網站怎麼去展示那些個URL

⑷ 使用thinkphp 怎麼實現反向代理

改自PHP Reverse Proxy PRP，修改了原版中的一些錯誤，支持了文件上傳以及上傳文件類型識別，支持指定IP，自適應SAE環境。

⑸ nginx 反向代理後為什麼訪問php文件 會提示404

可能的原因：

• nginx配置有誤，沒有將請求轉發到正確的處理程序（如php-fpm等），轉發到一個不版存在著的路權徑

• 請求已經轉發到php處理程序，但php處理程序配置沒有找到對應的腳本

• php已經處理了腳本，但代碼里返回了一個404的狀態碼

⑹ nginx 反向代理後為什麼訪問php文件 會提示404

||在Nginx的配置文件vhost.conf中，加入以下代碼實現rewrite。
若開啟所有規則.則添加如下代碼：
if ($request_filename !~* (.*)\.(css|js|gif|jpg|png|xml))
{
# 修改以下語句中的 /HDwiki 為你的HDwiki目錄地址，如果程序放在根目錄中，請將 /HDwiki 修改為 /
rewrite ^(/HDwiki)/(.*)$ $1/index.php?$2;
}

⑺ javaweb struts2 為什麼每次訪問 action都會報404 我確實有這個方法呀

404標識訪問不到資來源源
你可以先看一下你的項目名是否正確
然後檢查一下路徑
這些都沒問題再看配置，你的Struts的這段配置是沒有問題的
是不是存在反向代理的，如果代理到別的域名下，你也是訪問不到的
如果是配置的問題後台會拋異常出來的，這個時候返回的編碼就不是404了

⑻ 請教關於nginx配置404錯誤頁面

建議使用護衛神.nginx大師，一鍵安裝nginx+php+mysql_+ftp，在線配置nginx，包括404頁面的設置。

⑼ nginx 反向代理 google，出現 404，怎麼破

server {

listen 443 ssl;
server_name loacalhost;

access_log /etc/nginx/sites-available/ssl-access.log;
error_log /etc/nginx/sites-available/ssl-error.log;

ssl_certificate /home/usr/server.crt;
ssl_certificate_key /home/usr/server.key;

keepalive_timeout 60;

location / {
proxy_pass https://Address/;

proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Forwarded-Proto https;

proxy_redirect off;
}
}

⑽ 使用ngrok訪問項目總是出現404，不使用ngrok項目能正常運行

下面使用的介紹
ngrok.exe -config ngrok.cfg -subdomain bisouyi 8989
-config 指定配置文件
-subdomain 指定二級域名
8989 是指定映射到本地的哪一個埠
配置文件一般內不用管容,簡單到令人發指.
運行完命令,就能看到,它已經在運行了
當狀態是online的時候,就說明它已經運行正常了,現在用戶就可以通過訪問
