changelog:

in mijn voorbeeld zit ik in b104
ik gebruik adres-space 10.104.222
default gateway 10.104.255.254
dns nameservers 8.8.8.8

1. maak een tekening

   

2. clone een ubuntu16-xyz
3. check MACs
4. start en pas aan: /etc/hostname & /etc/hosts
   dont forget to put the unique name before localhost ...

   user@ubu16-NET-002:~$ cat /etc/hostname
   ubu16-NET-002

   user@ubu16-NET-002:~$ cat /etc/hosts
   127.0.0.1   ubu16-NET-002 localhost
   127.0.1.1   ubu16-NET-002

5. change /etc/network/interfaces for a static address

   user@ubu16-NET-002:~$ cat /etc/network/interfaces
   # This file describes the network interfaces available on your system
   # and how to activate them. For more information, see interfaces(5).
    
   source /etc/network/interfaces.d/*
    
   # The loopback network interface
   auto lo
   iface lo inet loopback
    
   # The primary network interface
   auto enp0s3
   iface enp0s3 inet static
   address 10.104.222.102
   netmask 16
   gateway 10.104.255.254
   dns-nameservers 8.8.8.8
    
   ## this interface on intnet
   auto enp0s8
   iface enp0s8 inet static
   address 192.168.11.1
   netmask 24

6. terminal op linuxmint
7. ssh naar je tweede server
   jos@vbox01:~$ ssh 10.104.222.102 -l user
8. ssh naar je eerste server
   jos@vbox01:~$ ssh 10.104.222.101 -l user
    
   de server 101 bevat een syslog server
   de server 102 wordt een ganglia server
    
9. firefox naar tweede server:
   ip-adres van server 102 in de url balk
   ik krijg:

   Today is Thursday 25th of November 2021 10:43:23 AM
   So who do you think you are, ...?
   My name is ubu16-NET-002 but most people call me The Server ..

   ^^^ zodra ik de correcte hostname en datum zie, betekent dit dat op mijn tweede server apache2 en php werken.
    
   ik kan nu beginnen aan de installatie van ganglia op mijn ubu16-NET-002.

2. kopieer de ganglia virtual host configuratie naar sites-enabled
sudo cp /etc/ganglia-webfrontend/apache.conf /etc/apache2/sites-enabled/ganglia.conf
    
   herstart apache2 om de ganglia virtual host te activeren:
   sudo service apache2 restart
    
   kijk in je firefox op /ganglia

   

    
   Als je dit ziet werkt de ganglia server
