Zabbix Proxies on CentOS 7

Image
Overview A Zabbix proxy can collect performance and availability data on behalf of the Zabbix server. This way, a proxy can take on itself some of the load of collecting data and offload the Zabbix server. Also, using a proxy is the easiest way of implementing centralized and distributed monitoring, when all agents and proxies report to one Zabbix server and all data is collected centrally. A Zabbix proxy can be used to: Monitor remote locations Monitor locations having unreliable communications Offload the Zabbix server when monitoring thousands of devices Simplify the maintenance of distributed monitoring Setting up Proxy Server We will be using a separate Linux server with CentOS 7 as the base operating system with MariaDB database server installed on it that will be used as a local database for Proxy server. So in this article we assume that you already had set up your Zabbix Server. [root@localhost ~]# rpm --import http://repo.zabbix.com/RPM-GPG...

Join CentOS 7 into Active Directory using realm and sssd

Image
Introduction to SSSD and Realmd   Staring from Red Hat 7 and CentOS 7, SSSD or 'System Security Services Daemon' and realm have been introduced. SSSD's main function is to access a remote identity and authentication resource through a common framework that provides caching and offline support to the system. SSSD provides PAM ans NSS integration and a database to store local users, as well as core and extended user data retrieved from a center server. The main reason to transition from winbind to sssd is that sssd can be used for both direct and indirect integration and allows to switch from one integration approach to another without significant migration costs. The most convenient way to configure SSSD or winbind in order to directly integrate a Linux system with AD is use the realm service. Because it allows callers to configure network authentication and domain membership in a standard way. The realm service automatically discovers information about accessib...
