nginx 记录到 syslog - 连接被拒绝

nginx 记录到 syslog - 连接被拒绝

我正在尝试设置 nginx 1.7.3 以将日志发送到 syslog，但是当我进行以下配置时：

server {
    access_log syslog:server=localhost;
}

这显示在 nginx 的错误日志中：

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)

我已经关注http://nginx.org/en/docs/syslog.html并尝试了其中指定的不同参数，但没有成功......

服务器运行 rsyslogd 守护程序并且其他应用程序（cron、mysql）在那里记录没有任何问题。

nginx 正在尝试通过网络端口发送您的日志，但您的 rsyslog 配置不允许接收 syslog。

您需要通过取消注释 UDP 或 TCP 系统日志接收配置来配置 rsyslog 以接受系统日志消息。nginx 可能默认为 UDP，因此我建议从那里开始。

不要忘记允许系统日志通过您可能配置的任何防火墙。
