1、出现此错误提示，表明uwsgi.ini或nginx.conf有问题，导致nginx 访问uwsgi被拒绝
2、解决方法：1、检查uwsgi.ini[uwsgi]socket = 127.0.0.1:8077chdir = /root/env/demowsgi-file = demo/wsgi.pyprocesses = 2threads = 4chmod-socket = 664vacuum = true2、检查nginx.confserver { listen 80 default_server; listen [::]:80 default_server; server_name localhost; charset utf-8; # Load configuration files for the default server block. # include /etc/nginx/default.d/*.conf; location / { root /root/env/demo; include /etc/nginx/uwsgi_params; uwsgi_pass 127.0.0.1:8077; } location /static { alias /root/env/ht/collected_static; } location /media { alias /root/env/ht/media; }}
3、如果上述还不能解决问题，查看SELinux状态：#getenforce用于解决：failed(13:Permissiondenied)whileconnectingtoupstream如果SELinux status参数为enabled即为开启状态修改/etc/selinux/config 文件将SELINUX=enforcing改为SELINUX=disabled
