Ganglia 3.4安装配置简述

首先强调一下，Ganglia采用组播模式（多播模式）进行数据请求。gmetad发送一个请求到一个组播地址（239.2.11.71），由于是组播地址，所以gmetad只需发送一次请求包即可完成对所有gmond的轮询。gmond收到请求后将采集到的数据返回给gmetad。

SERVER端安装：

apache：

1. wget http://labs.mop.com/apache-mirror//apr/apr-1.4.6.tar.gz
2. wget http://labs.mop.com/apache-mirror//apr/apr-util-1.5.1.tar.gz
3. wget http://www.fayea.com/apache-mirror/httpd/httpd-2.2.23.tar.gz
4.  
5. tar -xf apr-1.4.6.tar.gz && cd apr-1.4.6
6. ./configure --prefix=/usr/local/apr && make && make install
7.  
8. tar -xf apr-util-1.5.1.tar.gz && cd apr-util-1.5.1
9. ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
10. make && make install
11.  
12. tar -xf httpd-2.2.23.tar.gz && cd httpd-2.2.23
13. ./configure --prefix=/usr/local/apache2 --enable-so --enable-mods-shared=most --with-included-apr --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
14. make && make install
15. echo '/usr/local/apache2/bin/apachectl start' >>/etc/rc.d/rc.local
16.  
17. 启动
18. /usr/local/apache2/bin/apachectl start

php：

ganglia-web需要PHP JSON模块，该模块包含在PHP 5.2及其以上版本。PHP 5.1需要自行安装JSON模块，非常的麻烦。 

1. wget http://www.php.net/get/php-5.3.18.tar.gz/from/cn2.php.net/mirror
2. tar -xf php-5.3.18.tar.gz && cd php-5.3.18
3. ./configure --prefix=/usr/local/php-5.3 --with-apxs2=/usr/local/apache2/bin/apxs
4. make && make install

vim /usr/local/apache2/conf/httpd.conf，添加如下内容：

1. <FilesMatch \.php$>
2. SetHandler application/x-httpd-php
3. </FilesMatch>
4.  
5. <FilesMatch "\.ph(p[2-6]?|tml)$">
6. SetHandler application/x-httpd-php
7. </FilesMatch>
8.  
9. <FilesMatch "\.phps$">
10. SetHandler application/x-httpd-php-source
11. </FilesMatch>

01.找到<IfModule dir_module>配置段，添加index.php

重启apache，写一个index.php文件，进行测试访问：

http://SERVER/index.php

安装ganglia依赖：

libconfuse：

官方网站下载失败，下载了版本稍旧一点rpm包：ttp://pkgs.repoforge.org/libconfuse/

1. wget http://pkgs.repoforge.org/libconfuse/libconfuse-2.6-2.el5.rf.x86_64.rpm
2. wget http://pkgs.repoforge.org/libconfuse/libconfuse-devel-2.6-2.el5.rf.x86_64.rpm
3. rpm -ivh libconfuse-*

1. wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.31.tar.gz
2. tar -xf pcre-8.31.tar.gz && cd pcre-8.31
3. ./configure && make && make install
4.  
5. echo '/usr/local/lib' >/etc/ld.so.conf.d/libpcre.conf
6. ldconfig -v

1. yum -y install apr-devel apr-util check-devel cairo-devel pango-devel libxml2-devel rpmbuild glib2-devel dbus-devel freetype-devel fontconfig-devel gcc-c++ expat-devel python-devel libXrender-devel

1. wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz
2. tar -xf rrdtool-1.4.7.tar.gz && cd rrdtool-1.4.7
3. ./configure --prefix=/usr/local
4. make && make install
5.  
6. echo '/usr/local/lib' >/etc/ld.so.conf.d/librrd.conf
7. ldconfig -v

1. wget http://sourceforge.net/projects/ganglia/files/ganglia%20monitoring%20core/3.4.0/ganglia-3.4.0.tar.gz/download
2. tar -xf ganglia-3.4.0.tar.gz && cd ganglia-3.4.0
3. ./configure --prefix=/usr/local/ganglia --with-gmetad --with-librrd=/usr/local/lib --sysconfdir=/etc/ganglia
4. make && make install
5.  
6. cp gmond/gmond.init /etc/rc.d/init.d/gmond
7. cp gmetad/gmetad.init /etc/rc.d/init.d/gmetad
8. chkconfig --add gmond && chkconfig gmond on
9. chkconfig --add gmetad && chkconfig gmetad on
10.  
11. 修改/etc/rc.d/init.d/gmetad和/etc/rc.d/init.d/gmond，分别指定如下参数：
12. GMETAD=/usr/local/ganglia/sbin/gmetad
13. GMOND=/usr/local/ganglia/sbin/gmond

1. mkdir -p /var/lib/ganglia/rrds
2. chown nobody:nobody /var/lib/ganglia/rrds
3.  
4. gmond -t |tee /etc/ganglia/gmond.conf
5. vim /etc/ganglia/gmetad.conf，修改内容：
6. data_source "PPS Hadoop Cluster" $SERVER:8649 //把$SERVER替换成自己的被监控服务器IP
7. gridname "Hadoop"
8.  
9. vim /etc/ganglia/gmond.conf，修改cluster配置段内容：
10. name = "Hadoop Cluster"
