About log rotation

Server NGINX
1

hi,all
I found the way of the log rotation is below. And during the period
between
“mv” and “kill”, some logs will be lost because of the file doesn’t
exist
any more.
Is there any good ways?

thanks

nginx will re-open it’s logs in response to the USR1 signal.

$ mv access.log access.log.0
$ kill -USR1 cat master.nginx.pid
$ sleep 1
$ gzip access.log.0 # do something with access.log.0

No, the data will not be lost. Until a worker process keeps a file open
the worker is able to write to the file even the file was renamed or
deleted.
This is true for both Unix and Win32 (although in Win32 in you can not
delete
an open files, you can just to rename them).
