I have defined following global settings in nginx.conf:

access_log            /tmp/nginx/access.log;
error_log             /tmp/nginx/error.log info;
client_body_temp_path /tmp/nginx/client-body;

But nginx -c nginx.conf still gives following errors:

nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied) 2021/08/26

14:11:05 [emerg] 15099#0: mkdir() "/var/tmp/nginx/client-body" failed (13: Permission denied)

What gives?
