这篇文章主要介绍了详解Nginx 13: Permission denied 解决方案,小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

今天在用uwsgi+nginx在部署flask应用时，遇到502的错误，vim /var/log/nginx/error.log查看nginx的错误日志，提示如下错误信息：

2018/07/22 00:46:36 [crit] 15890#15890: *74 connect() to unix:/root/jianshuvue/jianshu.sock failed (13: Permission denied) while connecting to upstream, client: 120.42.13.98, server: , request: “GET /favicon.ico HTTP/1.1”, upstream: “uwsgi://unix:/root/jianshuvue/jianshu.sock:”, host: “”, referrer: “”

Permission denied，一看就知道是权限出了问题，通过ps -ef | grep nginx,查看nginx的进程信息

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 http://www.iis7.com/a/lm/vpsdq/

发现nginx进程的用户是nginx，而我们创建/root/jianshuvue/jianshu.sock文件的用户是root，因此，只要把nginx的进程user改为root即可，vim /etc/nginx/nginx.conf:

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

之后，/etc/init.d/nginx restart重启nginx，就可以正常访问网站了。
