nginx 错误提示:504 Gateway Time-out;upstream timed out (110: Connection timed out)

大家好。我是在全新的ubuntu16.04上按照seafile官方指南安装了seafile6.0.9。
在没有启动nginx的情况下,访问ip:8000正常,但在根据指南配置nginx后,发现不能访问,提示504 Gateway Time-out。

var/log/nginx/seahub.error.log错误信息如下:
2017/05/06 10:02:41 [error] 7157#7157: *1 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.142.1, server: 192.168.142.157, request: “GET / HTTP/1.1”, upstream: “fastcgi://127.0.0.1:8000”, host: “192.168.142.157”

/etc/nginx/site-enabled/seafile.conf的内容如下:
server {

}
location /media {

}
}

Ccnet.conf的配置:
[General]
USER_NAME = SEAFILETEST
ID = c2c0df82cdb1f329f5f468b7cfd091d927ec9feb
NAME = SEAFILETEST
SERVICE_URL = http://192.168.142.157

[Client]
PORT = 13419

[Database]
ENGINE = mysql
HOST = 127.0.0.1
PORT = 3306
USER = seafile
PASSWD = 123456
DB = ccnet-db
CONNECTION_CHARSET = utf8

seahub_settings.py的配置:
SECRET_KEY = “o9xb@jl7#hqh1i7m_!flgy4^!!h4^!h!eo2zgqfu-&1^$ypi(5”
FILE_SERVER_ROOT = ‘http://192.168.142.157/seafhttp
DATABASES = {
‘default’: {
‘ENGINE’: ‘django.db.backends.mysql’,
‘NAME’: ‘seahub-db’,
‘USER’: ‘seafile’,
‘PASSWORD’: ‘123456’,
‘HOST’: ‘127.0.0.1’,
‘PORT’: ‘3306’

问题已解决:
需要运行的是
seahub.sh start-fastcgi

我原来运行的是seahub.sh start

很抱歉
