Redhad Borrow CentOS Yum installation

RedHat Linux is installed by default, Yum software, but because of the reason for the activation of the authentication RedHat can not directly do yum install some software, if we need to install the software under the RedHat yum, we only use the source of Yum to change to CentOS is good, Then change all the variables in the source to the actual values so that you can use Yum to install the software we need directly.

Instructions for use

Installation
[email protected] ~]# Yum install ganglia-gmond-y
Yum installation automatically resolves headache-dependent package issues

S2, installation Gmetad

As described in the Gmond installation, if the local software library does not provide Gmetad, you will need to install Epel.
[email protected] ~]# Yum install ganglia-gmetad-y
You will find the following dependent packages installed:
Dependency installed:

S3, installation Gweb

Wiki:http://sourceforge.net/apps/trac/ganglia/wiki/ganglia-web-2#installation


Before you install and configure Gweb, check that you have
Meet the following requirements:
Apache Web Server
PHP 5.2 and later
Installation and enablement of PHP JSON extensions

First install Apache and PHP 5
[[email protected] ~]# yum install httpd PHP
You will find the following dependent packages installed:
Dependency installed:
apr-util-ldap.x86_64 0:1.3.9-3.el6_0.1 httpd-tools.x86_64 0:2.2.15-29.el6.centos mailcap.noarch 0:2.1.31-2.el6 php-c li.x86_64 0:5.3.3-27.el6_5 php-common.x86_64 0:5.3.3-27.el6_5

PHP-enabled JSON extensions are required, and JSON is already included in PHP 5.2 and later.
Check the status of the JSON extension by examining the/etc/php.d/json.ini file, and if the JSON extension is enabled, the file should contain something similar to the following statement:
Extension=json.ini

Download the latest version of Gweb (https://sourceforge.net/projects/ganglia/files/gweb/)
This example is currently the latest version of 3.5.12
[Email protected] ~]# wget http://ncu.dl.sourceforge.net/project/ganglia/ganglia-web/3.5.12/ganglia-web-3.5.12.tar.gz
[Email protected] down]# TAR-ZXVF ganglia-web-3.5.12.tar.gz
[Email protected] down]# CD ganglia-web-3.5.12

Compiling makefile
[Email protected] ganglia-web-3.5.12]# vim Makefile
You can view some user default configurations:
##########################################################
# User Configurables:
##########################################################
# location where Gweb should is installed to (excluding Conf, Dwoo dirs).
Gdestdir =/usr/share/ganglia-webfrontend


# location where default Apache configuration should is installed to.
Gconfdir =/etc/ganglia-web


# Gweb Statedir (where conf dir and dwoo templates dir is stored)
Gweb_statedir =/var/lib/ganglia-web


# Gmetad RootDir (parent location of RRD folder)
Gmetad_rootdir =/var/lib/ganglia


Apache_user = Www-data
##########################################################

To modify the default configuration:
Gdestdir =/var/www/html/ganglia2
Apache_user = Apache

Note: Gdestdir and Apache_user are consistent with DocumentRoot, Apache in Apache configuration files (/etc/httpd/conf/httpd.conf)

Make install

S4, status check

Check if httpd is started:
[[Email protected] ~]# service httpd status
Start httpd:
[[Email protected] ~]# service httpd start

Check if Gmetad is started:
[[Email protected] ~]# service Gmetad status
Start Gmetad:
[[Email protected] ~]# service Gmetad start

Check if the local Gmond is started:
[[Email protected] ~]# service Gmond status
Start Gmond:
[[Email protected] ~]# service Gmond start

S5, close SELinux

If you skip this step, the following exception will appear when you open http://<server IP address>/ganglia2:
There is an error collecting ganglia data (127.0.0.1:8652): Fsockopen Error:permission denied

What is SELinux?
Http://wiki.centos.org/zh/HowTos/SELinux

To view the SELinux status:
[Email protected] ~]# Sestatus
SELinux status:enabled
SELINUXFS Mount:/selinux
Current Mode:permissive
Mode from config file:enforcing
Policy version:24
Policy from config file:targeted

To turn off SELinux:
[Email protected] ~]# Setenforce 0
Setenforce This command can instantly switch between the enforcing and Permissive modes, but these changes will not be retained when the system reboots.
To be effective after the next boot, you need to modify the selinux= behavior enforcing within the/etc/selinux/config.

S6, access ganglia monitoring platform

Http://<server IP address>/ganglia2/

The directory "/GANGLIA2" can be modified in the Ganglia-web makefile file and will need to be recompiled after modification.
