Perform Installation of minimal Oracle Linux 8 (https://yum.oracle.com/ISOS/OracleLinux/OL8/u4/x86_64/x86_64-boot.iso)

Once installed, update all components and restart server.

yum -y update
shutdown -r now

You can run the below commands directly or using this command to execute via a bash script

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

Install optional software components

yum -y install glibc.i686
yum -y install man
yum -y install wget
yum -y install openssh-clients
yum -y install perl
yum -y install chkconfig
yum -y install perl-CPAN
yum -y install perl-DBD-Pg
yum -y install tcpdump
yum -y install net-snmp-utils net-snmp
yum -y install net-tools
yum -y install dstat
yum -y install iotop
yum -y install sysstat
yum -y install iptraf
yum -y install rsync


Please ensure that DNS is also configured for your network.

Enable network access by running the firewalld commands from Firewall_Management_in_Linux

Make folder to hold GigaFlow and related software.

mkdir /opt
mkdir /opt/software
cd /opt/software

Download Java and link to standard location

wget http://builds.anuview.net/beta/jre-8u202-linux-x64.rpm
rpm -i jre-8u202-linux-x64.rpm
ln -s /usr/java/jre1.8.0_202-amd64/ /opt/java

Check that java has installed

/opt/java/bin/java -version

Should output

java version "1.8.0_202"

Java(TM) SE Runtime Environment (build 1.8.0_202-b08)

Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)



Install postgres

//Current
//Add Postgres Yum Repository
rpm -Uvh https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
//Disable Appstream
dnf -qy module disable postgresql 
yum install postgresql11-server postgresql11 -y
/usr/pgsql-11/bin/postgresql-11-setup initdb
systemctl start postgresql-11.service
systemctl enable postgresql-11.service
mv /var/lib/pgsql/11/data/pg_hba.conf /var/lib/pgsql/11/data/pg_hba.conf.orig
wget -O /var/lib/pgsql/11/data/pg_hba.conf http://95.85.35.209/software/build/pg_hba.conf
systemctl stop postgresql-11.service
systemctl start postgresql-11.service

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

Download GigaFlow Software

wget -p http://95.85.35.209/software/ros_unix.tgz 
tar -vxzf /opt/software/95.85.35.209/software/ros_unix.tgz -C /

If this is a new installation, copy the service files

cp /opt/ros/resources/unix/rosd /etc/init.d/
cp /opt/ros/resources/unix/start /opt/ros/resources/
chmod 755 /etc/init.d/rosd
chmod 755 /opt/ros/resources/start
chmod 755 /opt/ros/resources/docs/sql/createmyipfixdb.sh
chkconfig --add rosd
chkconfig --level 345 rosd on

Initialise the anuview database

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


//Installation now complete!!

Start the service anuview service (rosd)

/etc/init.d/rosd restart

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.

Gigaflow install login.PNG
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.

Gigaflow install initial setup.PNG

Additional Information

Scheduler

echo "cfq" > /sys/block/sda/queue/scheduler

alter/add /etc/sysctl.d/swappiness.conf and set vm.swappiness = 10

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 /opt/postgresql/pg95/data

We have to be careful here if SELinux is enbaled to allow the new location via the semanage and restorecon commands shown below.

/etc/init.d/postgresql-95 stop
cp -rp /var/lib/pgsql/10//data /home/postgresdata/
mv /var/lib/pgsql/10//data /opt/postgresql/pg95/data_orig
ln -s /home/postgresdata/data/ /var/lib/pgsql/10/data
semanage fcontext -a -t postgresql_db_t '/home/postgresdata(.*/)?'
restorecon -R /home/postgresdata
/etc/init.d/postgresql-95 start

Once the move is complete and everything is confirmed working, you can remove the copy of the data folder (i.e. /opt/postgresql/pg95/data_orig) to reclaim that disk space.
