RHEL 7.1 compilation and installation of Ganglia 3.7.1

1. Install Dependencies

Yum groupinstall-y "Development tools" "Basic Web Server"

Yum install pcre-devel apr-util zlib-devel zlib rrdtool-devel rrdtool python-devel php

2. Add a user

Useradd ganglia

Passwd ganglia
3. Compile and install confuse from the source code.

Cd/usr/local/src

# Install confuse
Wget http://download.savannah.gnu.org/releases/confuse/confuse-2.7.tar.gz
Tar zxvf confuse-2.7.tar.gz
Cd confuse-2.7/
../Configure CFLAGS =-fPIC-disable-nls
Make & make install
Then compile and install ganglia

Wget http://sourceforge.net/projects/ganglia/files/ganglia%20monitoring%20core/3.7.1/ganglia-3.7.1.tar.gz/download

Mv download ganglia-3.7.1.tar.gz
Tar zxvf ganglia-3.7.1.tar.gz
Cd ganglia-3.7.1/
./Configure -- prefix =/usr/local/ganglia -- with-gmetad -- enable-gexec -- sysconfdir =/etc/ganglia -- with-python =/usr/bin/python
Make & make install
4. Configure gmetad and gmond.

Cp gmetad/gmetad. conf/etc/ganglia/

/Usr/local/ganglia/sbin/gmond-t | tee/etc/ganglia/gmond. conf
Configure gmetad first.

Vim/etc/ganglia/gmetad. conf

Data_source "my cluster" YOUR_FQDN
# Setuid_username "nobody"
Setuid_username "ganglia"
Then configure gmond.

Vim/etc/ganglia/gmond. conf

Setuid = yes
# User = nobody
User = ganglia
Udp_send_channel {
Bind_hostname = yes # Highly recommended, soon to be default.
# This option tells gmond to use a source address
# That resolves to the machine
Check the python extension of gmond to ensure that modpython. so is compiled.

Locate modpython. so

/Usr/local/ganglia/lib64/ganglia/modpython. so
# Create gmond python directory
Mkdir-p/usr/local/ganglia/lib64/ganglia/python_modules
/Usr/local/ganglia/sbin/gmond-d10
# Loaded module: python_module
# Copy python module/py. conf
Cp/usr/local/src/ganglia-3.7.1/gmond/python_modules/*. py/usr/local/ganglia/lib64/ganglia/python_modules
Cp/usr/local/src/ganglia-3.7.1/gmond/python_modules/conf. d/*. pyconf/etc/ganglia/conf. d
Configure the startup Item:

Cp gmetad/gmetad. init/etc/rc. d/init. d/gmetad

Cp gmond/gmond. init/etc/rc. d/init. d/gmond
Vim/etc/init. d/gemtad (edit these)
# GMETAD =/usr/sbin/gmetad
GMETAD =/usr/local/ganglia/sbin/gmetad
# Daemon $ GMETAD
Daemon $ GMETAD-c/etc/ganglia/gmetad. conf
Vim/etc/init. d/gmond (edit these)
# GMOND =/usr/sbin/gmond
GMOND =/usr/local/ganglia/sbin/gmond
# Daemon $ GMOND
Daemon $ GMOND-c/etc/ganglia/gmond. conf
Configure the systemd Service

Vim/usr/lib/systemd/system/gmetad. service (edit these lines)

[Service]
Type = forking
# PIDFile =/usr/local/ganglia/var/run/gmetad. pid
PIDFile =/var/run/gmetad. pid
# ExecStart =/usr/local/ganglia/sbin/gmetad -- pid-file =/usr/local/ganglia/var/run/gmetad. pid
ExecStart =/usr/local/ganglia/sbin/gmetad-c/etc/ganglia/gmetad. conf -- pid-file =/var/run/gmetad. pid
EnvironmentFile =-/etc/ganglia/default/gmetad

Vim/usr/lib/systemd/system/gmond. service (edit these lines)

[Service]
Type = forking
# PIDFile =/usr/local/ganglia/var/run/gmond. pid
PIDFile =/var/run/gmond. pid
# ExecStart =/usr/local/ganglia/sbin/gmond -- pid-file =/usr/local/ganglia/var/run/gmond. pid
ExecStart =/usr/local/ganglia/sbin/gmond-c/etc/ganglia/gmond. conf -- pid-file =/var/run/gmond. pid
Create a directory for rrdtool:

Mkdir-p/var/lib/ganglia/rrds

Chown ganglia: ganglia/var/lib/ganglia/rrds
Start the service:

Systemctl daemon-reload

Systemctl start gmetad
Systemctl start gmond
So far, netstat can see port listening, telnet localhost 8649, and xml. ps-ef confirms that gmetad and gmond are indeed running as ganglia users, "/var/lib/ganglia/rrds" directory contains file generation.

Netstat-tnlp

5. Configure ganglia-web

Wget http://sourceforge.net/projects/ganglia/files/ganglia-web/3.7.1/ganglia-web-3.7.1.tar.gz

Tar xzvf ganglia-web-3.7.1.tar.gz
Vi Makefile (Edit these)
GDESTDIR =/var/www/html/ganglia
APACHE_USER = apache
