以下動作皆在 DRBL server 上處理

Ganglia

1. Install (Base on Ubuntu Dapper) 1.1 Install necessary package from repository : apache2-php4, php4-gd, php4-jpgraph, php4-rrdtool, rrdtool, gcc, g++, libc6, librrd2-dev 1.1 Download last stable version ganglia

​http://sourceforge.net/project/showfiles.php?group_id=43021&package_id=35280 (In our case, use "ganglia-3.0.4.tar.gz" )

1.1 Uncompress package, and configure and make

$ tar xzvf ganglia-3.0.4.tar.gz; cd /ganglia-3.0.4
$ ./configure --with-gmetad --prefix=/opt/ganglia
$ make
$ sudo make install

1.4 Install Web Frontend:

$ cp -a web /var/www/ganglia }}} 1.2 Configure

1.2.0 Add a user, group for ganglia service, say "ganglia:ganglia" 1.2.1 On frontend, create a gmond configuration file named gmond.conf $ /opt/ganglia/sbin/gmond --default_config > /etc/gmond.conf

$ vi /etc/gmond.conf

globals {

daemonize = yes setuid = yes user = ganglia -------------> match 1.2.0 debug_level = 0 max_udp_msg_len = 1472 mute = no deaf = no host_dmax = 0 /*secs */ cleanup_threshold = 300 /*secs */ gexec = no

}

cluster {

name = "DRBL Cluster Project" -------------> as you want owner = "NCHC OSS Lab" -------------> as you want latlong = "unspecified" url = "unspecified"

} udp_send_channel {

host = 192.168.201.254 ---------------> match your LAN connection ip port = 8649

}

1.2.2 On frontend, create a Gmetad configuration file named gmetad.conf $ cp /opt/src/ganglia-3.0.4/gmetad/gmetad.conf /etc/gmetad.conf $ vi /etc/gmetad.conf

data_source "Test Cluster" 127.0.0.1:8649

trusted_hosts 127.0.0.1

setuid_username "ganglia"

1.2.3 On frontend, edit web frontend configuration file named conf.php $ vi /var/www/ganglia/conf.php

$gmetad_root = "/var/lib/ganglia"; $rrds = "$gmetad_root/rrds";

define("RRDTOOL", "/usr/bin/rrdtool");

$ganglia_ip = "127.0.0.1"; 1.3 Setup Ganglia service and start up

1.3.1 Perpare rrd log directory $ mkdir -p /var/lib/ganglia/rrds $ chown ganglia:ganglia /var/lib/ganglia/rrds

1.3.2 Setup service on /etc/rc.local ---------> client 要保留，或以其他方式起動 $ vi /ect/rc.local

# Start up ganglia service /opt/ganglia/sbin/gmond /opt/ganglia/sbin/gmetad --------> client 則可以不用

1.3.3 Start up necessary service $ /opt/ganglia/sbin/gmetad $ /opt/ganglia/sbin/gmond

1.4 Setup frontend php web page

1.4.1 Copy necessary frontend php scripts $ cp -a /opt/src/ganglia-3.0.4/web /var/www/ganglia 1.4.2 Make sure the follow session is correct in config.conf $ vi /var/www/ganglia/conf.php

$gmetad_root = "/var/lib/ganglia"; $rrds = "$gmetad_root/rrds";

define("RRDTOOL", "/usr/bin/rrdtool");

$ganglia_ip = "127.0.0.1";
