![Nginx 连接被拒绝错误 111,网关错误](https://linux22.com/image/127339/Nginx%20%E8%BF%9E%E6%8E%A5%E8%A2%AB%E6%8B%92%E7%BB%9D%E9%94%99%E8%AF%AF%20111%EF%BC%8C%E7%BD%91%E5%85%B3%E9%94%99%E8%AF%AF.png)
请不要急于将其作为重复项关闭。我在网上搜索,仍然找不到让它工作的方法。
这是我的工作目录:
/var/www/flaskapp
- myproject.ini
- myproject.py
- myproject.sock
- pycache
- 维尼夫
- wsgi.py
myproject.py
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "<h1 style='color:blue'>Hello There!</h1>"
if __name__ == "__main__":
app.run(host='0.0.0.0')
wsgi.py
from myproject import app
if __name__ == "__main__":
app.run()
myproject.ini
[uwsgi]
module = wsgi:app
master = true
processes = 5
socket = myproject.sock
chmod-socket = 660
vacuum = true
die-on-term = true
#location of log files
logto = /var/log/uwsgi/%n.log
我还创建了一个 systemd Unit 文件
/etc/systemd/system/myproject.service
[Unit]
Description=uWSGI instance serve myproject
After=network.target
[Service]
User = john
Group = www-data
WorkingDirectory=/var/www/flaskapp/
Environment="PATH=/var/www/flaskapp/venv/bin"
ExecStart=/var/www/flaskapp/venv/bin/uwsgi --ini myproject.ini
[Install]
WantedBy=multi-user.target
进而
sudo systemctl start myproject
sudo systemctl enable myproject
比nginx的配置。 nginx.conf 我保持不变,但对 /etc/nginx/sites-availible/myproject 进行了更正
server {
listen 83;
server_name my_external_ip;
location / {
include uwsgi_params;
uwsgi_pass unix:/var/www/flaskapp/flaskapp;
}
}
并通过命令创建了到 /etc/nginx/sites-enabled 的链接
sudo ln -s /etc/nginx/sites-available/myproject /etc/nginx/sites-enabled
之后: sudo systemctl restart nginx 并 sudo ufw 允许“Nginx Full”。
现在当我进入http://我的 IP 地址:83/我看到默认的 nginx 问候语,没有其他任何内容!虽然我认为这应该是我的Hello There!由我的 python 脚本制作。不知道为什么...
这是我的日志:
/var/log/nginx/error.log
2018/02/08 22:17:51 [error] 2394#2394: *1 connect() to unix:/var/www/flaskapp/venv failed (111: Connection refused) while connecting to upstream, client: 46.146.0.30, server: 92.240.202.184, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/var/www/flaskapp/venv:", host: "my_external_ip:83"
以及uwsgi的日志:

有人说我需要重新安装 uwsgi 并安装 pcre,但这样做后仍然没有成功,我确实尝试并搜索了与此相关的所有解决方案,但尽一切努力我什么也没得到。
请帮我发现问题然后处理它......
任何帮助将不胜感激!
提前致谢!
