在nginx子配置文件中加下面加粗字体部分

location / {
proxy_pass http://static;
proxy_redirect off;
proxy_set_header Host $host;
proxysetheader backendIP $upstreamaddr; #要代理的服务器的地址
proxysetheader backendCode $upstreamstatus; #要代理的服务器的状态

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

在主配置文件中
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"'
'"$upstream_addr" "$upstream_status"';
即可通过tailf /var/log/nginx/access.log 查看到
