Question

我正在与Nginx，Gunicorn和Ubuntu Linux服务器一起部署Flask项目。目前，我已经完成了一些操作，可以使用命令

手动启动服务器

gunicorn -w 4 -b 127.0.0.1:5000 run:app

以下是nginx.conf的内容

user www www;
worker_processes 2;
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; 
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll;
  worker_connections 65535;
}
http
{
  include mime.types;
  default_type application/octet-stream;
  log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
               '$status $body_bytes_sent "$http_referer" '
               '"$http_user_agent" $http_x_forwarded_for';

#charset gb2312;

 # server_names_hash_bucket_size 128;
 # client_header_buffer_size 32k;

  sendfile on;
  tcp_nopush on;

  gzip_vary on;

  limit_zone crawler $binary_remote_addr 10m;
        server {
                listen 80;
                server_name schoolping.westeurope.cloudapp.azure.com;
                index index.html index.htm index.php;
                location / {
                         proxy_pass http://127.0.0.1:5000;
                         proxy_set_header Host $host;
                         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

}
}

如果我只是从gunicorn -w 4 -b 127.0.0.1:5000 run：app开始，则该网站只能使用一段时间，然后，如果我尝试使用DNS访问该网站，则会显示给我504错误。

为解决此问题，我正在尝试使Gunicorn自动启动。因此，我在School.service中创建了一个名为/etc/systemd/system/的文件该文件的内容如下所示：

[Unit]
Description=Gunicorn instance to serve Flasky
After=network.target syslog.target

[Service]
User=www
Group=www
WorkingDirectory=/home/schoolproject/www/nginx-1.6.3/venv/bin/School
#Environment="path=/home/schoolproject/www/nginx-1.6.3/venv/bin"
ExecStart=/home/schoolproject/www/nginx-1.6.3/venv/bin/School/Code gunicorn -w 4 -b 127.0.0.1:5000 run:app

[Install]
WantedBy=multi-user.target

学校是项目的主要部分，run.py是执行文件，argus是“ app”。在我启动服务后

systemctl daemon-reload School
systemctl start School

然后我通过

检查了服务的状态

systemctl status School

它告诉我：

错误是权限被拒绝，但是我已经使用户“ www”成为文件夹/home/schoolproject/的所有者。我不知道下一步该怎么解决。有人帮我吗？

Gunicorn服务器无法在Ubuntu中启动
