By default when you install nginX on Linux a logrotate config file will be created in /etc/logrotate.d/nginx. Sometimes you may see that after a while logs inside of nginX access log is empty and it is logged into the file usually named access.log.1. This error happens when a process cannot close its file handler and has to write into access.log.1.

If you take a look at the config rotation of nginX you will see a part called postrotate that run a command, for nginx it is as below:

postrotate
     invoke-rc.d nginx rotate >/dev/null 2>&1
 endscript

If you run the command between postrotate and endscript it may gives the below error:

invoke-rc.d: action rotate is unknown, but proceeding anyway.
 invoke-rc.d: policy-rc.d denied execution of rotate.

Just remove a file related to i-MSCP:

rm /usr/sbin/policy-rc.d

NOTE: Or if you want to be safe rename it to something else.


Now you can run invoke-rc.d command and you should see a result like below:

[ ok ] Re-opening nginx log files: nginx.

Now every log will be directed to its file not it_file_name.log.1, and file handlers are closed safely.

#nginx #policy_rc #invoke_rc #log_rotate #rotate
