====> nginx: [emerg] mkdir() "/var/tmp/nginx/body" failed (2: No such file or directory)

====> sudo mkdir -p /var/tmp/nginx/body [ OK ]

$ sudo systemctl start nginx [ fails with the same error ]

a) setting /var/tmp/nginx/body world readable writable executable: same error
b) removing /var/tmp/nginx/body (leaving only) /var/tmp/nginx/: same error

This blocks our development, forcing us to install nginx under /opt

Thanks.

Are you removing directories tmp as used by systemd (PrivateTmp=true) or the one in your filesystem root?

Why are you using PrivateTmp=true in the first place?

Resolution: invalid
Status: newclosed

Feedback timeout.

To avoid human errors, nginx does not try to create intermediate directories, and only tries to create final directories specified in the configuration. In the described case there is no /var/tmp/nginx intermediate directory (due to PrivateTmp=true), so creating the /var/tmp/nginx/body directory fails.
