ganglia安装
ganglia是用于超大集群监控的利器，可以和Hadoop集群度量紧密集成。新版ganglia将内核功能模块和web展示模块是分开下载的。
下载ganglia内核
下载地址：http://downloads.sourceforge.net/project/ganglia/
[zhouhh@h185 ~]$ wget http://downloads.sourceforge.net/project/ganglia/ganglia%20monitoring%20core/3.4.0/ganglia-3.4.0.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fganglia%2Ffiles%2Fganglia%2520monitoring%2520core%2F&ts=1346899880&use_mirror=cdnetworks-kr-1
编译
[zhouhh@h185 ganglia-3.4.0]$ ./configure –with-gmetad checking for pthread_create in -lpthread… yes checking for pthread_create in -lpthreads… no checking rrd.h usability… no checking rrd.h presence… no checking for rrd.h… no checking for rrd_create in -lrrd… no Trying harder by including the X library path checking for rrd_create in -lrrd… no
The Ganglia Meta Daemon uses the Round-Robin Database Tool (rrdtool) for storing historical information. You have chosen to compile the monitoring core with gmetad but librrd could not be found. Please visit http://www.rrdtool.org/, download rrdtool and then try again
没找到rrdtool
安装rrdtool
[zhouhh@h185 ganglia-3.4.0]$ ./configure –with-gmetad –with-librrd=/usr/lib64/rrdtool … [zhouhh@h181 rrdtool-1.4.7]$ sudo yum -y install apr-devel apr-util check-devel cairo-devel pango-devel libxml2-devel glib2-devel dbus-devel freetype-devel fontconfig-devel gcc-c++ expat-devel python–devel libXrender-devel zlib libpng freetype libjpeg fontconfig gd libxml2 pcre pcre-devel
[zhouhh@h185 ~]$ wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz [zhouhh@h185 rrdtool-1.4.7]$ ./configure –prefix=/usr/lib64/rrdtool –disable-perl [zhouhh@h185 rrdtool-1.4.7]$ make [zhouhh@h183 rrdtool-1.4.7]$ sudo make install [zhouhh@h185 ganglia-3.4.0]$ ./configure –with-gmetad –with-librrd=/usr/lib64/rrdtool … Checking for confuse checking for cfg_parse in -lconfuse… no Trying harder including gettext checking for cfg_parse in -lconfuse… no Trying harder including iconv checking for cfg_parse in -lconfuse… no libconfuse not found
libconfuse是配置分析库
安装libconfuse
[zhouhh@h181 ganglia-3.4.0]$ sudo yum -y install libconfuse libconfuse-devel.x86_64 Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile
- base: mirrors.163.com
- extras: mirrors.163.com
- updates: mirrors.163.com Setting up Install Process No package libconfuse available. No package libconfuse-devel.x86_64 available. Error: Nothing to do
[zhouhh@h181 ganglia-3.4.0]$ cat /etc/redhat-release CentOS release 6.3 (Final)
下载并配置confuse
[zhouhh@h185 ~]$ wget http://download.savannah.gnu.org/releases/confuse/confuse-2.7.tar.gz
…
[zhouhh@h181 ganglia-3.4.0]$ ./configure –with-gmetad –with-librrd=/usr/lib64/rrdtool –sysconfdir=/etc/ganglia

编译安装 [zhouhh@h185 ~]$ sudo make&&install
配置ganglia
[zhouhh@h181 ganglia-3.4.0]$ gmetad -d 5 Going to run as user nobody Must be root to setuid to “nobody”
[zhouhh@h185 ~]$ sudo dmetad sudo: dmetad: command not found
[zhouhh@h185 ~]$ whereis gmetad gmetad: /usr/local/sbin/gmetad /usr/local/etc/gmetad.conf
添加/usr/local/sbin/到用户环境和sudo环境 [zhouhh@h185 ~]$ vi .bashrc
export PATH=$PATH:/usr/local/sbin
[zhouhh@h185 ~]$ source .bashrc
[zhouhh@h185 ~]$ sudo visudo
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin
修改权限
[zhouhh@h181 ~]$ mkdir -p /var/lib/ganglia/rrds [zhouhh@h181 ~]$ sudo chown nobody:nobody /var/lib/ganglia/ -R
测试
[zhouhh@h181 ~]$ sudo gmetad -d 5 Going to run as user nobody Sources are … Source: [my cluster, step 15] has 1 sources 127.0.0.1 xml listening on port 8651 interactive xml listening on port 8652 Data thread 140272050796288 is monitoring [my cluster] data source 127.0.0.1 cleanup thread has been started data_thread() for [my cluster] failed to contact node 127.0.0.1 data_thread() got no answer from any [my cluster] datasource
配置gmond
[zhouhh@h181 ~]$ sudo gmond -d 5 Configuration file ‘/usr/local/etc/gmond.conf’ not found.
loaded module: core_metrics loaded module: cpu_module loaded module: disk_module loaded module: load_module loaded module: mem_module loaded module: net_module loaded module: proc_module loaded module: sys_module
[zhouhh@h185 ~]$ sudo gmond –default_config > /usr/local/etc/gmond.conf -bash: /usr/local/etc/gmond.conf: Permission denied
[root@h181 zhouhh]# gmond –default_config > /usr/local/etc/gmond.conf
配置web环境
下载ganglia web
http://sourceforge.net/projects/ganglia/files/ganglia-web/
[zhouhh@h185 ~]$ wget http://downloads.sourceforge.net/project/ganglia/ganglia-web/3.5.2/ganglia-web-3.5.2.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fganglia%2Ffiles%2Fganglia-web%2F3.5.2%2F&ts=1347011991&use_mirror=cdnetworks-kr-1 Length: 1471659 (1.4M) [application/x-gzip]
[zhouhh@h185 ~]$ tar zxvf ganglia-web-3.5.2.tar.gz
因我的DocumentRoot目录在/home/www下面，所以需要修改一下Makefile
[zhouhh@h185 ganglia3]$ vi Makefile GDESTDIR = /home/www/default/ganglia
用浏览器访问http://h185/ganglia/
返回：
There was an error collecting ganglia data (127.0.0.1:8652): fsockopen error: Connection refused
原来ganglia的gmond和gmetad没起来
设置服务自启动环境
[zhouhh@h185 ganglia-3.4.0]$ sudo cp gmond/gmond.init /etc/rc.d/init.d/gmond [zhouhh@h185 ganglia-3.4.0]$ sudo chkconfig –add gmond [zhouhh@h185 ganglia-3.4.0]$ sudo chkconfig gmond on [zhouhh@h185 ganglia-3.4.0]$ sudo cp gmetad/gmetad.init /etc/rc.d/init.d/gmetad [zhouhh@h185 ganglia-3.4.0]$ sudo chkconfig –add gmetad [zhouhh@h185 ganglia-3.4.0]$ sudo chkconfig gmetad on [zhouhh@h185 ganglia-3.4.0]$ sudo vi /usr/local/etc/gmetad.conf data_source “myhadoop” h185 h181 gridname “MyHadoopGrid” [zhouhh@h185 ganglia-3.4.0]$ sudo service gmond start [zhouhh@h185 ganglia-3.4.0]$ sudo service gmetad start
[root@h185 gmond]# whereis gmond gmond: /usr/local/sbin/gmond /usr/local/etc/gmond.conf
需重新配置一下gmond.init和 gmetad.init，指到安装的目录。
[root@h185 gmond]# vi gmond.init GMOND=/usr/local/sbin/gmond [root@h185 gmond]# cp gmond.init /etc/rc.d/init.d/gmond [root@h185 gmetad]# vi gmetad.init GMETAD=/usr/local/sbin/gmetad [root@h185 gmetad]# cp gmetad.init /etc/rc.d/init.d/gmetad
[zhouhh@h185 ganglia-3.4.0]$ sudo service gmond start [zhouhh@h185 ganglia-3.4.0]$ sudo service gmetad start
用浏览器访问http://h185/ganglia/
返回正确的结果。
依次在其他需管理的机器配置gmond，并运行起来。
监控主机运行gmond和gmetad。
