# Zenoss 모니터링 서버를 CentOS에 설치 #

1. Disable SELinux and IPtables

For this guide SELinux and IPtables were completely disabled and CentOS 6 was up-to-date!

(* selinux의 설명 http://blog.naver.com/shackerz/220375507309 참조)

2. Add DNS FQDN Entry and NTP Sync

To ensure proper resolving FQDN entries in DNS or /etc/hosts must exist and please configure NTP time synchronization for services to run properly.

3. Install Following Packages

Install the following packages to make your life a bit easier – especially if you are on CentOS 6 minimal install.

[root@centos1 ~]# yum install openssh-clients wget vim-enhanced

4. Install Zenoss Dependencies Repository

This RPM installs Zenoss Dependency Repository. It will help us resolve all of the dependencies required to install and run Zenoss.

[root@centos1 ~]# rpm -ivh http://deps.zenoss.com/yum/zenossdeps-4.2.x-1.el6.noarch.rpm

5. Install MySQL Repository

Zenoss requires MySQL database server. We will download and install the latest MySQL server version available.

[root@centos1 ~]# rpm -ivh http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

6. Download and Install Oracle Sun Java

Download the latest Oracle Sun Java RPM from Java Downloads and transfer it to your server. Zenoss needs Oracle Java to run. Please install Oracle Sun Java RPM as follows.

[root@centos1 ~]# rpm -ivh jre-7u60-linux-x64.rpm 
Preparing... ########################################### [100%]
 1:jre ########################################### [100%]
Unpacking JAR files...
 rt.jar...
 jsse.jar...
 charsets.jar...
 localedata.jar...
 jfxrt.jar...

Remove existing java links and recreate them, pointing to Oracle Sun Java binaries.

[root@centos1 ~]# rm /usr/bin/java /usr/bin/javaws 
rm: remove symbolic link `/usr/bin/java'? y
rm: remove symbolic link `/usr/bin/javaws'? y
[root@centos1 ~]# ln -s /usr/java/latest/bin/java /usr/bin/java
[root@centos1 ~]# ln -s /usr/java/latest/bin/javaws /usr/bin/javaws

Check and make sure you are running Oracle Sun Java.

[root@centos1 ~]# java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

7. Install and Start Latest MySQL Server

Install the latest version of MySQL server and start it but DO NOT set MySQL server root password yet! This will enable Zenoss to automatically populate MySQL database.

[root@centos1 ~]# yum install mysql-community-server
[root@centos1 ~]# /etc/init.d/mysqld start

8. Download and Install Latest Zenoss RPM

Download latest Zenoss RPM to your server and install it via “yum” to resolve dependencies.

[root@centos1 ~]# wget http://downloads.sourceforge.net/project/zenoss/zenoss-4.2/zenoss-4.2.5/zenoss_core-4.2.5-2108.el6.x86_64.rpm
[root@centos1 ~]# yum localinstall zenoss_core-4.2.5-2108.el6.x86_64.rpm

9. Start Postfix Service

Postfix or other mail server needs to run to enable sending of Zenoss emails alerts.

(*메일 연동부분으로 Postfix 및 기타 메일 서버가 필요함)

[root@centos1 ~]# /etc/init.d/postfix start

10. Start Zenoss for the First Time

Zenoss first run might take some time. Zenoss has to populate the database and install ZenPacks, please be patient…

[root@centos1 ~]# /etc/init.d/zenoss start

Zenoss installation completed.

DEBUGGING:

• If starting Zenoss fails with “Failed starting rabbitmq — exiting!” please add a line to /etc/hosts with the IP address of the Zenoss server and FQDN and try starting Zenoss again!
• If when you visit web URL only see HTML only output something went wrong at the first time Zenoss run. Please remove Zenoss “yum remove zenoss-4.2.5-2108.el6.x86_64”, reinstall RPM “yum localinstall zenoss_core-4.2.5-2108.el6.x86_64.rpm” and run Zenoss again for the first time.

UPDATE: Thanks to GeekPeek.Net visitor Sujith if you are having problems when accessing the login page for the first time (HTML only view) you can get it resolved by using script from the link HERE.

11. Visit Zenoss from Web Browser

Visit http://ip_address_or_hostname:8080 with your browser and follow initial Zenoss steps.

Picture 1 – Install Zenoss Monitoring Server – Click on “Get Started”

 

Picture 2 – Install Zenoss Monitoring Server – Set administrator password and a new user account

 

Install Zenoss Monitoring Server – Picture 3 – Specify or auto discover monitored devices

12. Make Services Start at Boot

[root@centos1 ~]# chkconfig mysqld on
[root@centos1 ~]# chkconfig zenoss on
[root@centos1 ~]# chkconfig postfix on

13. Start SNMP Service On Clients

If you want to add clients to Zenoss you first need to start the SNMP service on these clients (usually snmpd daemon) and allow Zenoss Monitoring Server to connect to SNMP daemon via firewall (iptables).

The default port SNMP runs on is 161 UDP and if you leave client SNMP configuration default (community name “public”) most of things should be up and running – of course it is advised to change the SNMP community name accordingly but also configure this when adding clients to Zenoss!
