Install and use Zabbix on Cent. Powerbook G4 12 Inch User Manual. OS 7 or RHEL 7. Tweet. Zabbix is a monitoring tool which is widely used in all kinds of environments. Unfortunately this also means that the learning curve can be rather high.

This post will go a little deeper into the installation process and the first steps in Zabbix. Zabbix can be installed from most standard repositories in a variety of Linux distributions. For this post, I’m using Cent. OS 7 and I decided to use the official Zabbix. Zabbix requires a database backend and for this post, I will use Maria. DB (a fork of My. SQL). Add the Zabbix repository and install the packages.

The first step is to enable the Zabbix official repository by creating a file in /etc/yum. If you haven’t done so, add that repo too. Don’t get confused with all the references to My. SQL in the commands below. Maria. DB is a fork of My.

SQL and clearly branding! Success! By default, a Maria.

DB installation has an anonymous user, allowing anyoneto log into Maria. DB without having to have a user account created forthem. Success! Normally, root should only be allowed to connect from 'localhost'. Success! By default, Maria.

DB comes with a database named 'test' that anyone canaccess. Success! Reloading the privilege tables will ensure that all changes made so farwill take effect immediately. Reload privilege tables now? Success! Cleaning up.. All done! Use the root- password which you changed in the previous step when asked for a password and replace secretpassword with your own password for the zabbix database user.

The schema is delivered with Zabbix in. For a production environment you really need some tuning in Maria. DB to optimize the database system. To do so, I recommend using Zabbix for a while and then use. This approach is very straightforward and delivers very good results with a minimal effort.

Configure the webserver. At this point, our database is ready so the next step is to configure the webserver (Apache) and PHP.

The default parameters of PHP need some tuning for Zabbix. You can also edit the file by hand if you would like to. Next up is Apache.

The Yum- installation, created a file for Apache in. Edit this file to look similar to this: 1. Zabbixmonitoringsystemphpwebfrontend#Alias/zabbix/usr/share/zabbix< Directory.

It needs to know the password which we set for the zabbix database user earlier. Replace secretpassword with your own password which you set for the. I’m assuming that outgoing traffic is allowed, otherwise you also need to open up UDP 1. SNMP and TCP. The only thing that is left is to start the services related to Zabbix and finish the configuration by using the webinterface: Start the services. If all goes well, you should see something like this: Click next and check if everything is marked with OK: In the next step, enter the details about the Maria. DB user which we created (named zabbix and password secretpass): Continue to step 6 and finish the installation: After clicking finish, you should see the login screen to your new Zabbix installation: The default username is admin and the default password for that user is zabbix. At this point the Zabbix server is ready to use.

Basic actions for hosts to monitor: Now that we have our Zabbix server up and running, we need to have something to monitor. For several types of hosts, there is an agent available. The agent is listening for requests on TCP port . Replace 1. 92. 1. IP or hostname of your Zabbix- server: 1. It creates a service for the Zabbix agent and starts it. Enable snmp on Linux.

Besides using the Zabbix agent, you can also monitor hosts using SNMP. SNMP isn’t always as fast and flexible as the agent but does the job. Also SNMP can be used for devices that can’t have an agent installed (like a switch): Install the net- snmp package.

For SNMP, remove the Agent interface and add an SNMP interface containing the same information. On the templates tab, add ICMP ping and a template that matches the host (for example “Template OS Linux” for a Linux host with a Zabbix agent or “Template SNMP OS Linux” for a Linux host with SNMP). When using SNMP, you need to enter the community string which you have chose (public in my example above) on the Macros tab: Finally click Add and the host should be monitored. Don’t panic if you don’t see information iimmediately give Zabbix some time to discover all items that are relevant for the host. This should be all it takes to get started with Zabbix.

Take some time to explore Zabbix’ functionality and experiment to discover all features.

Enterprise Linux GIS - OSGeo Wiki The ELGIS repository is not maintained any more, use EPEL. Enterprise Linux (EL) and derivatives (that is, Red Hat Enterprise Linux, Cent.

OS and Scientific Linux) is a popular and robust platform for servers and computing- heavy workstations, and is therefore a good fit for GIS specific requirements. Subscribers to the mailing- list are basically the community around ELGIS and are meant to be consulted for important choices (like which packages to support). Please have a look at this list before asking the mailing- list for support on a particular problem.

They maintain versions of packages which cannot be maintained in EPEL, or that EPEL does not want to keep at the latest stable version. This is where our packaging effort currently takes place, and can be seen as a kind of backport repository.

ELGIS requires EPEL to be configured as an additional repository. It contains quite a few GIS packages and base libraries. Note that one of the rules of the packages maintained in EPEL is that they should never require to change the base EL distribution. Moreover they rather follow Enterprise Linux policy of not using the latest version of the software but rather to stick with a given version in order to ensure stability and predictability. PGRPMS provides the latest versions of Postgre.

SQL (e. g. This is an option if you just want to run Post. GIS and needs recent Postgre. SQL features as well. PGRPMS is NOT compatible with ELGIS, don't enable both or you will break your environment.

OS 5. You can find some mock config files here. Don't hesitate to ask on the mailing- list if you need support for your first mock builds: this is much easier than it seems, and very clean. Then send you spec file to the mailing- list or give download access to an SRPM. Therefore EL specific questions related to GIS packages from EPEL are welcome on the ELGIS list, and information about them will be documented in the other resources provided by the OSGeo foundation (wiki, trac, etc.)How To. How to hack and locally build the ELGIS packages. ELGIS6 packages are now maintained in Git repositories which are forks from Fedora/EPEL Git repositories. In order to build a package (here: geos).

Cent. OS / Redhat: Install KVM Virtualization Software. KVM (Kernel- based Virtual Machine) is a full virtualization solution for Linux on x. Intel VT or AMD- V. How do I install KVM under Cent.

OS or Red Hat Enterprise Linux version 5. The Linux kernel 2. KVM. RHEL 5. 5 (and upcoming RHEL 6) supports KVM out of box and it has also been ported to Free.

BSD as a loadable kernel module. However, this tutorial is tested on both Cent. OS and RHEL 5. 5 only running 6.

Intel Xeon CPU (with Intel VT) and 6. SELinux running in enforcing mode. Why KVM? XEN allows several guest operating systems to execute on the same computer hardware and it is also included with RHEL 5. But, why use KVM over XEN? KVM is part of the official Linux kernel and fully supported by both Novell and Redhat. Xen boots from GRUB and loads a modified host operating system such as RHEL into the dom. KVM do not have concept of dom.

U. It uses /dev/kvm interface to setup the guest operating systems and provides required drivers. See the official wiki for more information. Required Packages.

You must install the following packages: kmod- kvm : kvm kernel module(s)kvm : Kernel- based Virtual Machinekvm- qemu- img : Qemu disk image utilitykvm- tools : KVM debugging and diagnostics toolspython- virtinst : Python modules and utilities for installing virtual machinesvirt- manager : Virtual Machine Manager (GUI app, to install and configure VMs)virt- viewer: Virtual Machine Viewer (another lightweight app to view VM console and/or install VMs)bridge- utils : Utilities for configuring the Linux Ethernet bridge (this is recommended for KVM networking)KVM Package Group. RHEL comes with KVM software group which includes full virtualization support with KVM. You can list all packages in the group as follows: # yum groupinfo KVMSample outputs: Loaded plugins: rhnplugin, security. Setting up Group Process.

Description: Virtualization Support with KVM. Mandatory Packages. Default Packages. Virtualization- en- US. Optional Packages. A Note About libvirtlibvirt is an open source API and management tool for managing platform virtualization.

It is used to manage Linux KVM and Xen virtual machines through graphical interfaces such as Virtual Machine Manager and higher level tools such as o. Virt. See the official website for more information. A Note About QEMUQEMU is a processor emulator that relies on dynamic binary translation to achieve a reasonable speed while being easy to port on new host CPU architectures.

When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x.

Power. PC, and S3. See the official website for more information. A Note About Virtio Drivers. Virtio is paravirtualized drivers for kvm/Linux.

With this you can can run multiple virtual machines running unmodified Linux or Windows VMs. Each virtual machine has private virtualized hardware a network card, disk, graphics adapter, etc. According to Redhat: Para- virtualized drivers enhance the performance of fully virtualized guests. With the para- virtualized drivers guest I/O latency decreases and throughput increases to near bare- metal levels. It is recommended to use the para- virtualized drivers for fully virtualized guests running I/O heavy tasks and applications.

Host Operating System. Your main operating system such as Cent. OS or RHEL is known as host operating system. KVM is a Linux kernel module that enables a modified QEMU program to use hardware virtualization. You only need to install KVM under host operating systems. KVM Domains. It is nothing but a guest operating system running under host operating system.

Each kvm domain must have a unique name and ID (assigned by system). Guest Operating Systems. KVM supports various guest operating systems such as.

MS- Windows 2. 00. Server. MS- Windows 7 / Vista / XPFree.

BSDOpen. BSDSun Solaris. Various Linux distributions. Net. BSDMINIXQNXMS DOSFree. DOSHaiku. Amiga Research OSInstall KVMType the following command to install KVM under RHEL or Cent.
