server {
listen 80;
server_name localhost;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
location / {
proxy_pass http://127.0.0.1:8080/;
}
}
proxy_set_header Host $host:$server_port; 这段比较关键之前我没加$server_port就老是到下级请求出现真实端口号。
