testVmap

location ^~ /mp/
{
#proxy_cache api_cache;
proxy_set_header Host mp.weixin.qq.com;
rewrite /mp/(.+)$ /$1 break;
proxy_pass https://mp.weixin.qq.com;
}

最后改成了根据请求路径转发

感谢大家，最后配置如下
服务器 A 的转发配置
location ^~ /namesg/ {
proxy_pass http://172.16.16.11;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
}

服务器 B 的 nginx.conf log 配置

log_format my_format '$http_x_real_ip -'
'$remote_addr- [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log my_format;


主要是 nginx 日志取消注释后还不能生效，需要改下日志名字

A 服务器的日志能正常获取到真实 IP

@lshero 是要怎么配置，要修改 log_format 吗

A 服务器转发配置
location ^~ /sogood {
proxy_pass http://172.16.0.7:81;
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header Cookie $http_cookie;
proxy_set_header Referer $http_refere;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
#proxy_set_header X-Forwarded-For $remote_addr;
#proxy_set_header REMOTE-HOST $remote_addr;

}


B 服务器转发配置
location ~ \.php$ {
proxy_pass http://127.0.0.1;
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header Cookie $http_cookie;
proxy_set_header Referer $http_refere;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}



加了感觉还是没用

@xcai 谢谢了

感谢大家了，升级到最新 5.6.37 搞定了
