nginx: [emerg] "upstream" directive is not allowed

upstream backend 位置放错了, upstream位置应该放在http模块里面 但必须是在server模块的外面

http
{
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    ..................................................

    upstream con {
    server 127.0.0.1:8080;
}
}
对此段代码放入httpd模块中，重启服务可完成问题的解决。
