How to Fix NGINX Logging Issue

Overview

How to Fix NGINX Logging Issue

NGINX Logging Issue

  • After looking into NGINX DEBUG & other I’d found nothing related to this issue.
  • So I’d decided to run the logrotate command manually and see what’s going on.
$ cat /etc/logrotate.d/nginx
/var/log/nginx/*.log {
	daily
	missingok
	rotate 14
	compress
	delaycompress
	notifempty
	create 0640 www-data adm
	sharedscripts
	prerotate
		if [ -d /etc/logrotate.d/httpd-prerotate ]; then \
			run-parts /etc/logrotate.d/httpd-prerotate; \
		fi \
	endscript
	postrotate
		invoke-rc.d nginx rotate >/dev/null 2>&1
	endscript
}
  • When I run the post rotate script manually it’s through errors.
^_^[root@mitesh.com:~]# invoke-rc.d nginx rotate
initctl: invalid command: rotate
Try `initctl --help' for more information.
invoke-rc.d: initscript nginx, action "rotate" failed.
  • That clearly means we have to look into post rotate script.

Fix All Servers using Ansible

  • I hate manually run same command on nearly hundred of servers.
  • Ansible is a good way to automate this boring work.
$ ansible ALL -m shell -a "sudo sed -i 's/invoke-rc.d nginx rotate/service nginx rotate/' /etc/logrotate.d/nginx"
$ ansible ALL -m shell -a "sudo service nginx rotate"

NOTE!: If you are not sure what is Ansible then check out some Ansible Tutorials.
