View service Gmetad Status

Error Gmetad dead but Subsys locked

View Tail-f/var/log/messages Discover the need to add directories and modify gmetad.conf files

(1) Mkdir-p/var/lib/ganglia/rrds (this directory is to configure the RRD data to save the file path, to the Web interface, this is fixed, preferably in a Web folder, and give the correct permissions, the default is the path, you can self-/opt/ Modify the value of the Rrd_rootdir variable in modules/ganglia/etc/gmetad.conf)

After the installation is complete httpd will have Apache this user, execute the following statement to the Rrds directory appropriate permissions

Chown-r Apache:apache/var/lib/ganglia/rrds

(2) Modify Setuid_username "Apache" in gmetad.conf the username and the RRD Data directory are required to match the owner

Note:

Gmetad.conf Modify the following:

Data_source "mycluster" 192.168.56.101:8649

Gridname "Mygrid"

Setuid_username "Apache"

Restart

Service Gmetad Restart

}

#bind_hostname = yes # highly recommended, soon to is default.

# That's resolves to the machine ' s hostname. Without

5, Ganglia-web Installation

Yum-y Install httpd PHP

Tar xzf ganglia-web-3.6.2cd ganglia-web-3.6.2

Modify the Makefile File

########################################################### User configurables:################################# ########################## location where Gweb should is installed to (excluding Conf, Dwoo dirs). Gdestdir =/var/www/html/ganglia# location where default Apache configuration should is installed to. Gconfdir =/etc/ganglia-web# Gweb statedir (where conf dir and dwoo templates dir is stored) Gweb_statedir =/var/lib/gang lia-web# Gmetad RootDir (parent location of rrd folder) Gmetad_rootdir =/var/lib/gangliaapache_user = apache############# #############################################

Modify the path address of the RRDtool execution file in the conf_defalut.php file, which affects the chart of the page display monitoring

# $conf [' gmetad_root '] = "/var/lib/ganglia"; $conf [' rrds '] = "${conf[' gmetad_root ']}/rrds"; $conf [' rrdtool '] = "/opt/ Rrdtool-1.4.9/bin/rrdtool ";
