Haproxy forwarding real IP to the Web

1. Add the following parameters to the haproxy.cfg.

Option Forwardfor #如果后端服务器需要获得客户端真实ip需要配置的参数, must be placed under the Listen module

2. If it is Apache, add the following parameter (i.e. modify)

Logformat "\"%{x-forwarded-for}i\ "%l%t \"%r\ "%>s%b \"%{referer}i\ "\"%{user-agent}i\ "" combined is mainly "\"%{ X-forwarded-for}i\ This parameter can record IP

Here we can write so conveniently cut logs Logformat "%{x-forwarded-for}i%l%t \"%r\ "%>s%b \"%{referer}i\ "\"%{user-agent}i\ "" Combined note space Class, can be copied directly

3. If the backend web is Nginx, add the following parameters

Set_real_ip_from IP, (this IP is filled with proxy IP)

Real_ip_header x-forwarded-for;

Log_format Main ' $remote _addr– $remote _user [$time _local] "$request" '

' $status $body _bytes_sent ' $http _referer '

' "$http _user_agent" "$http _x_forwarded_for" '

============================================= (The following log path is also defined as main and Apache, which belongs to a log format)

Add $remote_addr or $http_x_forwarded_for parameters to the Log_format.
