Nginx配置

#location配置
#以下为2种方式，一种是unix sock，另外一种为tcp
upstream hello-test {
    server unix:///tmp/srv_m.sock;
    #server 127.0.0.1:5001;
}


server {
    listen       8080;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        uwsgi_pass  hello-test;
        #非常重要，不要忘记
        include uwsgi_params;
