CentOS 6.4 minimal installation before Ganglia Installation

Description

The ganglia project is really useful for Cluster Monitoring. Unfortunately, there are too many dependencies to install it.

The following uses the CentOS6.4 minimal system as the initial environment. After installing the system, only the NIC service system is enabled as the installation environment for ganglia,

7. Install the ganglia background service and set
Install
Wget http://sourceforge.net/projects/ganglia/files/ganglia%20monitoring%20core/3.4.0/ganglia-3.4.0.tar.gz/download
Tar-xf ganglia-3.4.0.tar.gz & cd ganglia-3.4.0

Copy to the service and set the startup
Cp ganglia-3.4.0/gmond. init/etc/rc. d/init. d/gmond
Cp ganglia-3.4.0/gmetad. init/etc/rc. d/init. d/gmetad
Chkconfig -- add gmond & chkconfig gmond on
Chkconfig -- add gmetad & chkconfig gmetad on
Modify service configuration information
Modify the/etc/rc. d/init. d/gmetad file to change the GMETAD variable to: GMETAD =/usr/local/ganglia/sbin/gmetad
And change the gmond variable to: GMOND =/usr/local/ganglia/sbin/GMOND in the/etc/rc. d/init. d/gmond file.
Set the storage location of rrd
Mkdir-p/var/lib/ganglia/rrds
Chown nobody: nobody/var/lib/ganglia/rrds
Generate a gmond configuration file and modify the configuration information (optional)
/Usr/local/ganglia/sbin/gmond-t | tee/etc/ganglia/gmond. conf

Cd/usr/local/apache2/htdocs/ganglia
Modify the GDESTDIR and APACHE_USER parameters in Makefile, and then execute make install to install
GDESTDIR =/usr/local/apache2/htdocs/ganglia
APACHE_USER = daemon
Make install
Modify the php configuration file
Cp conf_default.php conf. php
Modify the conf. php file
If you set the storage location of rrd according to the above settings, you can skip the changes to $ conf ['gmetad _ root'] and $ conf ['rrds, otherwise, change to the corresponding location.
$ Conf ['rdtool'] = "/usr/local/bin/rrdtool ";
$ Conf ['external _ location'] = http: // localhost/ganglia;
$ Conf ['case _ sensitive_hostnames '] = false;
9. Start ganglia
Start or restart httpd
/Usr/local/apache2/bin/apachectl start
Start gmetad
Service gmetad start
Start gmond
Service gmond start
Ii. Install the client
1. Install Dependencies
Yum-y install apr-devel apr-util
2. Install libconfuse
Same as server
3. Install pcre
Same as server
4. install and configure ganglia
Install
Tar-xf ganglia-3.4.0.tar.gz & cd ganglia-3.4.0
./Configure -- prefix =/usr/local/ganglia -- sysconfdir =/etc/ganglia & make install & cd ..
Configuration
Copy server configurations
Scp ip:/etc/rc. d/init. d/gmond/etc/rc. d/init. d/gmond
Mkdir/etc/ganglia
Scp ip:/etc/ganglia/gmond. conf/etc/ganglia
Add gmond to the service and start it on
Cp ganglia-3.4.0/gmond. init/etc/rc. d/init. d/gmond
Chkconfig -- add gmond & chkconfig gmond on
5. Start the ganglia Client
/Etc/init. d/gmond start
Iii. Special Requirements
If your server has two NICs, eth0 uses the public network address and eth1 uses the LAN address, the communication between your monitoring server and the monitored server you want to use the LAN address to reduce the load on the Internet Nic, you can use the following command
Ip route add 239.2.11.71 dev eth1
Because 239.2.11.71 is the default multi-point transmission channel of ganglia, you need to add a route so that it can pass through eth1, that is, the Intranet Nic. For the address 239.2.11.71, you can go to/etc/ganglia/gmond. modify in conf
