我在AWS上创建了一个EC2实例,并在其上部署了django应用程序。
还在AWS上创建了RDS postgres数据库。每当我访问公共IP时,都会出现以下错误,
/
处的OperationalError无法连接到服务器:连接被拒绝服务器正在运行 在主机“ localhost”(127.0.0.1)上并接受TCP / IP连接 端口5432?
EC2和RDS实例都已连接。通过以下方式验证,
Nginx配置:
server {
listen 80;
server_name 18.218.45.241;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/ubuntu/Crowdsocial_project;
}
location / {
include proxy_params;
proxy_pass http://unix:/home/ubuntu/Crowdsocial_project/crowdsocial.sock;
}
}
Gunicorn配置:
