Gunicorn nginx 反代获取真实 ip 地址

闺蜜圈的后台服务使用 gunicorn 运行，对外接口通过 nginx 进行反代。但是反代有个问题，那就是 gunicorn 获取到的服务器的 ip 地址都是 127.0.0.1。

作为一个强迫症能忍受这个？那自然不行啊。

在 nginx 配置文件中增加 proxy_set_header

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

修改 gunicorn 启动参数，修改日志格式为：

--access-logformat='%({X-Real-IP}i)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(f)s" "%(a)s"'

重启 nginx 以及 gunicorn 服务,就可以记录真实 ip 地址了：

参数说明：

h is the remote address
l is - (not used)
u is - (not used, reserved)
t is the time stamp
r is the status line
s is the status of the request
b is length of response
f is referrer
a is user agent
You can also customize it with the following extra variables that are not used by default:

T - request time (in seconds)
D - request time (in microseconds)
p - the process id
{Header}i - request header (custom)
{Response}o - response header (custom)
