Tengine的多server的问题

安全组开了8080. 没开防火墙。
conf是独立的。
为什么 8080端口就是起不来？
netstat 看不到？

访问更不行？

1.conf

server{

listen 8080;
server_name 1.2.3.4;
location / {
    proxy_pass http://1.8.7.8:80;
    proxy_set_header Host $host:$server_port;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

}

2.conf

server{

listen 80;
server_name 1.2.3.4;
location / {
    proxy_pass http://1.8.7.8:80;
    proxy_set_header Host $host:$server_port;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}

}
