以下動作皆在 DRBL server 上處理 == Ganglia == 1. Install (Base on Ubuntu Dapper) * Install necessary package from repository : apache2-php4, php4-gd, php4-jpgraph, php4-rrdtool, rrdtool, gcc, g++, libc6, librrd2-dev[[BR]] * Download last stable version ganglia, In our case, use "ganglia-3.0.4.tar.gz" {{{ http://sourceforge.net/project/showfiles.php?group_id=43021&package_id=35280 }}} * 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 }}} * Install Web Frontend: {{{ $ cp -a web /var/www/ganglia }}} 2. Configure * Add a user, group for ganglia service, say "ganglia:ganglia" * On frontend, create a gmond configuration file named gmond.conf {{{ $ /opt/ganglia/sbin/gmond --default_config > /etc/gmond.conf }}} * Edit file: /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 } }}} * On frontend, create a Gmetad configuration file named gmetad.conf {{{ $ cp /opt/src/ganglia-3.0.4/gmetad/gmetad.conf /etc/gmetad.conf }}} * Edit file /etc/gmetad.conf {{{ data_source "Test Cluster" 127.0.0.1:8649 trusted_hosts 127.0.0.1 setuid_username "ganglia" }}} * On frontend, edit web frontend configuration file "/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 * Perpare rrd log directory {{{ $ mkdir -p /var/lib/ganglia/rrds $ chown ganglia:ganglia /var/lib/ganglia/rrds }}} * Start up service during booting, add the follow into file /etc/rc.local '''---------> client 要保留,或以其他方式起動''' {{{ # Start up ganglia service /opt/ganglia/sbin/gmond /opt/ganglia/sbin/gmetad '''--------> client 則可以不用''' }}} * Start up necessary service now {{{ $ /opt/ganglia/sbin/gmetad $ /opt/ganglia/sbin/gmond }}} 1.4 Configure frontend php web page * Copy necessary frontend php scripts {{{ $ cp -a /opt/src/ganglia-3.0.4/web /var/www/ganglia }}} * Make sure the follow session be set correctly file "/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"; }}}
