nginx 記錄到 syslog - 連接被拒絕

我正在嘗試設置 nginx 1.7.3 以將日誌發送到 syslog，但是當我進行此配置時：

server {
   access_log syslog:server=localhost;
}

這顯示在 nginx 的錯誤日誌中：

2015/01/15 21:42:47 [error] 16776#0: send() failed (111: Connection refused)
2015/01/15 21:42:48 [error] 16776#0: send() failed (111: Connection refused)
2015/01/15 21:42:50 [error] 16776#0: send() failed (111: Connection refused)

我已經關注了http://nginx.org/en/docs/syslog.html並嘗試了其中指定的不同參數，但沒有運氣……

伺服器在那裡執行 rsyslogd 守護程序和其他應用程序（cron、mysql）日誌，沒有任何問題。

nginx 正在嘗試通過網路埠發送您的日誌，但您的 rsyslog 配置不允許接收 syslog。

您需要通過取消註釋 UDP 或 TCP syslog 接收配置來配置 rsyslog 以接受 syslog 消息。nginx 可能預設為 UDP，所以我建議從那裡開始。

不要忘記允許系統日誌通過您可能配置的任何防火牆。
