nginx反向代理访问速度慢

[枫桥]

nginx反向代理访问速度慢， 配置如下
server {
listen 80;
server_name localhost:8080;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {
proxy_pass http://localhost:8080;
}
日志：

目测是不能创建nginx.pid这个文件
将localhost改为127.0.0.1后速度正常，可以正常创建nginx.pid这个文件，但是为什么localhost不可以呢？原因有谁知道吗

你在 hosts 文件加上 127.0.0.1 localhost 就可以用 localhost 了
