回傳參數

location ~ \.php$ {
    return 200 $args; add_header Content-Type text/plain;
    return 200 $uri; add_header Content-Type text/plain;
    return 200 $document_root; add_header Content-Type text/plain;
    return 200 $request_uri; add_header Content-Type text/plain;
}
  • $args：get 參數（e.g. ?page=2）
  • $uri：網址路徑（e.g. /tag/laravel）
  • $document_root：網頁路徑（e.g. /var/web/laravel/public）
  • $request_uri：完整請求 URI（/tag/laravel?page=2）

測試 site-enabled 設定

nginx -t

413 Request entity too large

Nginx 預設檔案上傳大小為 100M，可以修改設定值提高上傳檔案大小

sudo vim /etc/nginx/nginx.conf

打開 nginx.conf 後，在 http 設定值中加入 client_max_body_size 並修改上傳檔案大小

若沒有此設定值可自行加入

http {
    client_max_body_size 100M;
}

could not build server_names_hash, you should increase server_names_hash_bucket_size: 64

在新增 Nginx 主機時，發現網址名稱有過長的問題

$ systemctl status nginx.service

● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

Mar 07 08:28:21 tnl-dev systemd[1]: nginx.service: Failed with result 'exit-code'.

此時可以到 /etc/nginx/nginx.conf 將 server_names_hash_max_size 設定更高的數值

server_names_hash_max_size 512;
server_names_hash_max_size 1024;

設定完後重新啟動 Nginx 就可以正常啟動了
