前言

最近在研究云監控的相關工具,感覺ganglia頗有亮點,能從一個集群整體的角度來展現數據. 但是安裝過程稍過復雜,相關依賴稍多,故寫此文章與大家分享下.

本文不講解相關原理,若想了解請參考其他資料.?

本文目的: 即使之前未觸過ganglia,也能按照文中步驟搭建自己的ganglia監控集群.

啟用配置

5.編譯安裝

5.1 安裝ganglia (全部節點都要安裝)

#?tar?-zxf?ganglia-3.6.0.tar.gz #?cd?ganglia-3.6.0 #?./configure?--prefix=/usr/local/ganglia?--with-gmetad?--enable-gexec?--with-python=/usr/local Welcome?to..______??????????????????___/?____/___?_____??____?_/?(_)___?_/?/?__/?__?`/?__?\/?__?`/?/?/?__?`//?/_/?/?/_/?/?/?/?/?/_/?/?/?/?/_/?/\____/\__,_/_/?/_/\__,?/_/_/\__,_//____/Copyright?(c)?2005?University?of?California,?BerkeleyVersion:?3.6.0 Library:?Release?3.6.0?0:0:0Type?"make"?to?compile. #?make?&&?make?install

5.2 安裝ganglia-web (主節點安裝)

#?tar?-zxf?ganglia-web-3.5.10.tar.gz?-C?/export/home/ganglia/ #?cd?/export/home/ganglia/ganglia-web-3.5.10 #?cp?conf_default.php?conf.php

vi conf.php ? ?調整為如下內容

$conf['gweb_confdir']?=?"/export/home/ganglia/ganglia-web-3.5.10"; $conf['gmetad_root']?=?"/export/home/ganglia";

vi header.php?

<?php session_start(); ini_set('date.timezone','PRC');??????--修改時區為本地時區if?(isset($_GET['date_only']))?{$d?=?date("r");echo?$d;exit(0); }

配置臨時目錄

cd?/export/home/ganglia/ganglia-web-3.5.10/dwoo mkdir?cache chmod?777?cache mkdir?compiled chmod?777?compiled

5.3 安裝apache (主節點安裝)

tar?-zxf?httpd-2.2.23.tar.gzcd?httpd-2.2.23./configure?--prefix=/usr/local/apache2make?&&?make?install

5.4 安裝php (主節點安裝)

tar?-zxf?php-5.4.10.tar.gz cd?php-5.4.10 ./configure?--prefix=/usr/local/php??--with-apxs2=/usr/local/apache2/bin/apxs??--with-mysql=/usr make??&&?make?install

5.5?使用apache發布ganglia-web (主節點安裝)

vi /usr/local/apache2/conf/httpd.conf

.... Listen?80 ....<IfModule?dir_module>DirectoryIndex?index.html?index.phpAddType?application/x-httpd-php?.php </IfModule> ....#?在文件最后增加如下內容 #?ganglia Alias?/ganglia?"/export/home/ganglia/ganglia-web-3.5.10" <Directory?"/export/home/ganglia/ganglia-web-3.5.10">AuthType?BasicOptions?NoneAllowOverride?NoneOrder?allow,denyAllow?from?all </Directory>

啟動httpd服務

/usr/local/apache2/bin/apachectl?restart

6.配置Ganglia

6.1 配置gmetad (主節點配置)

cd?ganglia-3.6.0 cp?./gmetad/gmetad.init?/etc/init.d/gmetad cp?./gmetad/gmetad.conf?/usr/local/ganglia/etc/

vi?/etc/init.d/gmetad ?--修改如下內容

GMETAD=/usr/local/ganglia/sbin/gmetad

vi?/usr/local/ganglia/etc/gmetad.conf ? ? -- 修改如下內容

data_source?"duangr-cluster"?10?duangr-1??duangr-2??duangr-3 xml_port?8651 interactive_port?8652 rrd_rootdir?"/export/home/ganglia/rrds" case_sensitive_hostnames?0

修改rrds數據目錄所有者

chown?-R?nobody:nobody?/export/home/ganglia/rrds

啟動gmetad服務,并設為開機自動運行?

service?gmetad?restart chkconfig?--add?gmetad

6.2 配置gmond (全部節點配置)

cd?ganglia-3.6.0 cp?./gmond/gmond.init?/etc/init.d/gmond? ./gmond/gmond?-t?>?/usr/local/ganglia/etc/gmond.conf

vi?/etc/init.d/gmond ?--修改如下內容

GMOND=/usr/local/ganglia/sbin/gmond

vi?/usr/local/ganglia/etc/gmond.conf ? ? ?-- 修改如下內容

cluster?{name?=?"duangr-cluster"owner?=?"nobody"latlong?=?"unspecified"url?=?"unspecified" }

復制python module到ganglia部署目錄

mkdir?/usr/local/ganglia/lib64/ganglia/python_modules cp?./gmond/python_modules/*/*.py??/usr/local/ganglia/lib64/ganglia/python_modules

安裝程序ganglia-3.6.0默認提供了一些python module的配置文件,只需要部署到 /usr/local/ganglia/etc/conf.d 目錄下面即可生效

若對默認提供的這些監控腳本不太關心,可以跳過下面這步:

cp?./gmond/python_modules/conf.d/*.pyconf??/usr/local/ganglia/etc/conf.d

啟動gmond服務,并設為開機自動運行

service?gmond??restart chkconfig?--add??gmond
