Install Ganglia3.6.0 and configure Ganglia3.6.0 in Centos6.x

Recently, Ganglia was installed. Since the Linux base was basically 0, it took a great deal of trouble. Finally, after many failures, I finally saw the coveted web interface. The following is a summary of my work over the past few days.

Ganglia is a monitoring software that includes three parts: Gmond, Gmetad, and Gweb. Install Gmond on the host to be monitored. Gmetad collects information about the current host. Gmetad is deployed on the server side. It trains the host and collects the host information collected by Gmond, then it is stored in the rrdtool database. Gweb is a front-end interface that reads the rrd file saved by Gmetad and displays it on the web interface.

Deployment Plan:

Check for effectiveness

Ldconfig-v | grep "libpython2.7.so"

4. Install Gmond on the client

Because the client only needs to install Gmond, it is relatively simple.

[Plain] view plaincopyprint?

1. Tar-zxfganglia-3.6.0.tar.gz
2. # Cdganglia-3.6.0
3. #./Configure -- prefix =/usr/local/ganglia

tar -zxf ganglia-3.6.0.tar.gz# cd ganglia-3.6.0# ./configure --prefix=/usr/local/ganglia 

After the installation, claim the Gmond configuration file and modify:

[Html] view plaincopyprint?

1. Vi/usr/local/ganglia/etc/gmond. conf

vi /usr/local/ganglia/etc/gmond.conf

This name is the cluster name and must correspond to the server.

We can add Gmond to the startup script.

GMOND=/usr/<code class="bash functions">local</code><code class="bash plain">/ganglia/sbin/gmond</code>

In this way, we have configured and started Gmond.

1. Servicegmondstart

service gmond start

We can check through telnet

5. Server installation and configuration

The preceding operations are the same as those on the client. During re-compilation, since we need to install gmetad here, we need to add -- with-gmetad

[Plain] view plaincopyprint?

1. ./Configure -- prefix =/usr/local/ganglia -- with-gmetad -- enable-gexec -- with-python =/usr/local

./configure --prefix=/usr/local/ganglia --with-gmetad --enable-gexec --with-python=/usr/local

Modify configuration file

[Plain] view plaincopyprint?

1. Vi/usr/local/ganglia/etc/gmetad. conf

vi /usr/local/ganglia/etc/gmetad.conf

This is the data source we need to collect. The first is the cluster name, and the second is the ip address of the host in the cluster.

Rrd_rootdir is the location where data is collected to the storage. We can see that the default storage path is/var/lib/ganglia/rrds. We can customize the storage location. I did not. I used this location directly. Therefore, you need to create a directory

[Plain] view plaincopyprint?

1. Mkdir/var/lib/ganglia/rrds

mkdir /var/lib/ganglia/rrds

We need to change the permission of this directory. Otherwise, the interface will not be displayed if no data is collected on Gweb.

[Plain] view plaincopyprint?

1. Chown-Rnobody: nobody/var/lib/ganglia/rrds

chown -R nobody:nobody /var/lib/ganglia/rrds

OK. Gmetad configuration is complete.

6. install and configure Gweb

I think this part is the most difficult to configure, and many errors have been made in this step...

In fact, Gweb is a front-end program that relies on apache and php. For details about how to configure the two, refer to this post:

We think apache and php have been configured. Let's start Gweb.

Download and decompress

[Plain] view plaincopyprint?

1. Tar-zxfganglia-web-3.5.10.tar.gz

tar -zxf ganglia-web-3.5.10.tar.gz 

Copy the ganglia-web-3.5.10 directory. You can set the location by yourself. I got this location.

[Plain] view plaincopyprint?

1. /Var/lib/ganglia-web-3.5.10

/var/lib/ganglia/ganglia-web-3.5.10

Go to this directory and modify its configuration file.

He has a default configuration file conf_defalut.php. The program first looks for conf. php. If this file is not available, it will read conf_default.php.

[Html] view plaincopyprint?

1. Viconf. php

vi conf.php

You can check the following parameters.

The following parameter specifies the gweb home directory. In my opinion, webpage data can be read here when the interface is displayed on the foreground.

The following rrds is the location where gweb reads the rrd data stored in gmetad. Gmetad_root hasn't understood it yet .... It's okay.

The following is a php-compiled templates storage. We need to create these two files in the corresponding location and modify their permissions.

This is the path to the rrdtool directory. Because we have installed yum, we do not need to modify it here.

OK. Finally, it's done...

7. Page display

8. Notes

During the installation process, some errors are inevitable. For example, if some packages are missing, you can install them using Yum or source code. In addition, the front-end interface may not be displayed. This is probably because seLinux is not closed. The method for disabling seLinux is cd/usr/local setenforce 0.
