This article mainly introduces how to solve the problem of Nginx 13: Permission denied, the article is very detailed, has a certain reference value, interested friends must read it!

When you encounter a 502 error when deploying flask applications with uwsgi+nginx, vim / var/log/nginx/error.log looks at the error log of nginx and prompts the following error message:

00:46:36 on 2018-07-22 [crit] 1589015890: * 74 connect () to unix:/root/jianshuvue/jianshu.sock failed (13: Permission denied) while connecting to upstream, client: 120.42.13.98, server: jianshu.weiweiblog.cn, request: "GET / favicon.ico HTTP/1.1", upstream: "uwsgi://unix:/root/jianshuvue/jianshu.sock:", host: "jianshu.weiweiblog.cn", referrer: "http://jianshu.weiweiblog.cn/jianshu/67eb7ed414d3"

Permission denied, you can see that there is a problem with the permission. Use ps-ef | grep nginx to view the process information of nginx:

Root 15889 1 0 00:01? 00:00:00 nginx: master process / usr/sbin/nginx-g daemon on; master_process on

Www-data 15890 15889 0 00:01? 00:00:00 nginx: worker process

Root 16795 15654 0 00:48 pts/3 00:00:00 grep-color=auto nginx

It is found that the user of the nginx process is nginx, and the user we created the / root/jianshuvue/jianshu.sock file is root, so just change the process user of nginx to root, vim / etc/nginx/nginx.conf:

# user www-data;user root;worker_processes auto;pid / run/nginx.pid

After that, / etc/init.d/nginx restart restarts nginx, and you can visit the website normally.
