本地 Varnish IP 附加到 nginx 访问日志中的真实 IP
Local Varnish IP getting appended to real IP in nginx access logs
我在 Web 服务器上使用 Varnish + nginx，我试图让 access.log 中访问我网站的用户的真实 IP，我能够让它工作，但是对于出于某种原因，我的本地 IP（来自 运行 的一个 Varnish）也被附加到日志条目中，如下所示：
1.2.3.4, 127.0.0.1 - - [08/Oct/2020:10:39:39 +0100] "GET / HTTP/1.1" 200 488 "https://website.com/example" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36"
其中1.2.3.4为真实IP。
我尝试将 set_real_ip_from 和 real_ip_header 添加到我的服务器块 nginx 配置中，但这似乎没有帮助。这是我正在使用的 log_format：
log_format main '$http_x_forwarded_for - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent "$http_referer" ' '"$http_user_agent"';
这是我的网站配置：

有什么建议吗？
根据您的日志格式，一切都按预期工作：
log_format main '$http_x_forwarded_for - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent "$http_referer" ' '"$http_user_agent"';
请注意您如何记录 X-Forwarded-For header 的值，而不是 IP。
如果您想要真正的 IP，请将 $remote_addr 与您已经尝试过的指令一起使用：
log_format main '$remote_addr - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent "$http_referer" ' '"$http_user_agent"';
set_real_ip_from 127.0.0.1;
real_ip_header X-Real-IP;
real_ip_recursive on;
回顾一下：real_ip_* nginx 指令将根据请求来源和 X-Forwarded-For（或其他指定的具有真实 IP 的 header）更改 $remote_addr 变量的值价值。它们不会影响 X-Forwarded-For 本身的值。
我在 Web 服务器上使用 Varnish + nginx，我试图让 access.log 中访问我网站的用户的真实 IP，我能够让它工作，但是对于出于某种原因，我的本地 IP（来自 运行 的一个 Varnish）也被附加到日志条目中，如下所示：

其中1.2.3.4为真实IP。
我尝试将 set_real_ip_from 和 real_ip_header 添加到我的服务器块 nginx 配置中，但这似乎没有帮助。这是我正在使用的 log_format：

有什么建议吗？
根据您的日志格式，一切都按预期工作：
log_format main '$http_x_forwarded_for - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent "$http_referer" ' '"$http_user_agent"';
请注意您如何记录 X-Forwarded-For header 的值，而不是 IP。
如果您想要真正的 IP，请将 $remote_addr 与您已经尝试过的指令一起使用：
log_format main '$remote_addr - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent "$http_referer" ' '"$http_user_agent"';
set_real_ip_from 127.0.0.1;
real_ip_header X-Real-IP;
real_ip_recursive on;
回顾一下：real_ip_* nginx 指令将根据请求来源和 X-Forwarded-For（或其他指定的具有真实 IP 的 header）更改 $remote_addr 变量的值价值。它们不会影响 X-Forwarded-For 本身的值。
