2019/01/27 15:18:30 [crit] 23475#0: *39947969 open() "/xxdata/nginx/proxy_temp/4/44/0000200444" failed (13: Permission denied) while reading upstream, client: 110.70.240.98, server: api.xuexintest.com, request: "GET /training-srv/jy/report/downLoad/273e658b-d6a9-45ad-bdf5-893fcd261700?fileType=0&kd=1&zt=1&fx=1&jd=1&dp=1&ly=1&kdkp=1&subjectCode=chemistry&xnID=sjl HTTP/1.1", upstream: "http://10.17.16.104:1300/training-srv/jy/report/downLoad/273e658b-d6a9-45ad-bdf5-893fcd261700?fileType=0&kd=1&zt=1&fx=1&jd=1&dp=1&ly=1&kdkp=1&subjectCode=chemistry&xnID=sjl", host: "ai.test.com"分析问题及解决方法：
分析问题：出错原因是work进程没有打开/xxdata/nginx/proxy_temp/4/03/0000000034 文件的权限。work进程属于nginx用户组，nginx用户名。因此只要把proxy_temp 目录权限赋给nginx用户组，nginx用户名就可以了。
解决问题：
[[email protected] nginx]# chown -R nginx:nginx ./proxy_temp/
[[email protected] nginx]# ll proxy_temp/
