• run the commands directly (details provided in Manual Installation Section)

Bash script

Open the terminal enter "sudo bash", press enter and specify your password. Then run the command below

bash <(curl -s https://update.viavisolutions.com/v18/ObserverGigaFlow_Install_Oracle8.4.sh)

When script is finished the installation is completed. For the verification go to the Verification Section

/usr/pgsql-16/bin/postgresql-16-setup initdb
systemctl enable postgresql-16
systemctl start postgresql-16.service
mv /var/lib/pgsql/16/data/pg_hba.conf /var/lib/pgsql/16/data/pg_hba.conf.orig
curl -o /var/lib/pgsql/16/data/pg_hba.conf https://update.viavisolutions.com/v18/ObserverGigaFlow_pg_hba.conf.txt
systemctl stop postgresql-16.service
systemctl start postgresql-16.service

If asked, Leave port as 5432, enter password as P0stgr3s_2ME, set started at boot = y

Download GigaFlow Software

curl -o ObserverGigaFlowUnixx64.tgz https://update.viavisolutions.com/latest/ObserverGigaFlowUnixx64.tgz
tar -vxzf ./ObserverGigaFlowUnixx64.tgz -C /
chown -R gigaflow:viavi /opt/ros
chmod 755 /opt/ros/resources/unix/*.sh
chmod 755 /opt/ros/resources/docs/linux/*.sh
chmod 755 /opt/ros/resources/docs/sql/*.sh
/opt/ros/resources/unix/updatepost.sh

If this is a new installation, copy the service files

cp /opt/ros/resources/unix/gigaflow.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable gigaflow
systemctl start gigaflow.service
journalctl -u gigaflow.service

Initialise the gigaflow database

chmod 755 /opt/ros/resources/docs/sql/createmyipfixdb.sh
su - postgres < /opt/ros/resources/docs/sql/createmyipfixdb.sh

Start the service GigaFlow service

 systemctl restart gigaflow.service

The installation is completed. For the verification go to the Verification item

Verification

You should now be able to access the application on http://IP_ADDRESS:7902

The default user is "admin" and the default password is "admin"

Linux Startup Settings

This is the login page for GigaFlow, the default login credentials are Username:admin and Password:admin On this page you can also see details about the current version of Gigaflow which you are accessing.

When you log in for the first time, you will be prompted for some information. Server name is the name that you want to know this server as. It doesn't have to be the servers hostname. This name will appear in the web browser title bar. Minimum Free Space tells GigaFlow what the minimum free space that it should try to maintain on the disk (before purging old data). This should typically be 10% of your total disk space.

Additional Information

If you want to move an existing data folder to a new location (i.e. to a larger partition) you can use

e.g. move existing data folder to new location (/home/postgresdata) and link back to original /var/lib/pgsql/11/data

systemctl stop gigaflow
systemctl stop postgresql-11
rsync -av /var/lib/pgsql/11/data/ /data/gigaflow
mv /var/lib/pgsql/11/data /var/lib/pgsql/11/data_old
ln -s /data/gigaflow /var/lib/pgsql/11/data
chown postgres:postgres /var/lib/pgsql/11/data
chmod 0700 /var/lib/pgsql/11/data
systemctl start postgresql-11
systemctl start gigaflow
