Installation procedure

Motivation (1/3)

The APAN Tokyo XP and TransPAC2 NOC support many demonstrations and experiments over multi-domain networks throughout the year. However, there are some inefficiencies with the current support model.

APANTokyoNW1

We’d like to make it easy to discover the available network data on other networks and see it on standardized format.

Checking the network data of other networks

It’s not easy to get the network data of all networks and see its graphs1. Search the web page for the data2. Check what data is available3. Recognize the different format of the graphs

and data.

Inefficiency of support for demos and experiments

Motivation (2/3)

Preparation for network performance measurement

We’d like to make it easy to discover the available performance measurement servers on the other networks and do measurement immediately

Date and Time

MuchTime !

It takes so much time to do performance measurement 1. Check the available measurement servers

and tools on other networks2. Exchange the information about the

measurement servers3. Coordinate the measurement schedule4. Exchange the measurement data

Motivation (3/3)

We’d like to make it easy to discovery the available network data on other networks and see it on standardized format.

We’d like to make it easy to discovery the available performance measurement servers on the other networks and do measurement immediately

What we can do

Efficient support for events Looking at whole network data over multi-domain network

efficiently Measuring the network performance immediately between

domains

Advanced monitoring Monitoring the multi-domain network Integrated monitoring with several network metrics

Contribution to research activity Providing network data in quasi-real-time while researcher is

doing experiment. Providing measurement data to people who research the

routing /path control

Installation Report v0.9http://www.jp.apan.net/noc/perfSONAR/installation-report-v0.9.doc

OS & Basic setting

OS ＆ Basic Setting （Brief)

OS Basic Installation for the server Select “Server-GUI” at “set of software” section Add some packages for development SELinux is “Disabled”

Basic Setting Update the installed packages Stop unnecessary services(daemons) Change run level Configure TCP Wrapper Configure Perl CPAN

OS installation（All host)

1. Download the disk image from CentOS Web page below and make an install disk.

2. CentOS Download -http://www.centos.org/modules/tinycontent/index.php?id=15

3. Insert the install disk you created to CD or DVD drive then boot the server.

4. Set parameters depends on your environment within install wizard[Items of install wizard]

– Language – arbitrary setting – Keyboard – arbitrary setting – Disk Partition – arbitrary setting– Network – setting depend on your environment– Time zone – arbitrary setting– Root Password – arbitrary setting– Package – see next slide

Package （All host)

Select [ Server-GUI ] and check [ Customize now ] .

Select following packages as additional packages.

Group PackageApplication Development Libraries

Development Tools

Legacy Software Development

Basic setting （All host)

You do basic setting after package install and rebooting.• Firewall – default setting• SElinux – Select [disabled] (To avoid unexpected

access denied) • Time – arbitrary setting• User account – arbitrary setting• Sound card – arbitrary setting• Reboot the server

Package update (All host)

A lot of initial packages are needed to update due to security and functional reason. We manage RPM packages by using yum

Set up for yum# yum -y install yum-fastestmirror

Add new repository, DAG# rpm --import http://dag.wieers.com/rpm/packages/RPM-

GPG-KEY.dag.txt# vi /etc/yum.repos.d/dag.repo

(see installation report)

Update the packages# yum -y update

Unnecessary Linux Services

Stop Unnecessary Linux ServicesTo improve security level, save system resource and avoid the

performance problems, turn off unnecessary Linux services

# /sbin/service <SERVICE> stop & /sbin/chkconfig<SERVICE> off

Unnecessary services for perfSONAR-PS are belowavahi-daemon, bluetooth, cups, hidd, ipmi, irqbalance, lvm2-monitor, nfslock, pcscd, xfs, isdn, setroublesboot

Run level & TCP Wrapper

Run levelChange the run level to turn off X window.

# vi /etc/inittabid:3:initdefault:

TCP WrapperFor control the access.

# vi /etc/hosts.allowALL : < Allowed host># vi /etc/hosts.denyALL : ALL

perfSONAR-PS packages are available at CPAN. We install them by using CPAN.

So, configure the CPAN

# cpanWe have to reconfigure CPAN.pm due to following uninitialized parameters:following messages are only question. Explanation messages are snipped.Are you ready for manual configuration? [yes] CPAN build and cache directory? [/root/.cpan]<snip>
