Sudoers

The deploy script is not intended to advise which approach you should implemented nor deploy the sudoers configuration but the user that will run the script needs to have sudo privileges for some checks.

There are two options to setting up sudoers for the user:

  1. Provided sudo all
~# cat /etc/sudoers.d/user_zabbix
Defaults:zabbix !syslog
Defaults:zabbix !requiretty

zabbix	ALL=(ALL)  NOPASSWD:ALL
~#
  1. Limited acccess to run command with sudo
~# cat /etc/sudoers.d/user_zabbix
Defaults:zabbix !syslog
Defaults:zabbix !requiretty

zabbix ALL=(ALL) NOPASSWD: /usr/bin/lsof *
zabbix ALL=(ALL) NOPASSWD: /bin/ps *
~#
