devstack installation - controller node

 


0. sudo hostnamectl set-hostname compute-141


1. Remove any symlik of /etc/resolve.conf and add

nameserver 8.8.8.8

nameserver 8.8.4.4


2. check df -h [ /, should have good space]


3. checl internet connectivity,


ping www.google.com


4. if possible disable Ipv6, ip allocation


/etc/netplan/50-cloud-init.yaml 



5. And host name entry in /etc/host



give root as default user and sudo priviledge


sudo useradd -s /bin/bash -d /opt/stack -m stack



echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

 RAN Elements  Antennas  convert electrical signals into radio waves. Radios  transform digital information into signals that can be sent wirelessly and ensure that transmissions are in the correct frequency bands with the right power levels. Baseband units ( BBUs )  provide a set of signal processing functions that make wireless communication possible. Traditional baseband uses custom electronics combined with multiple lines of code to enable wireless communication, typically using the licensed radio spectrum. BBU processing detects errors, secures the wireless signal and ensures that wireless resources are used effectively. RAN Radio Resources  Radio Resources Management Techniques  Power control, scheduling, cell search, cell reselection, handover, radio link or connection monitoring, and connection establishment and re-establishment. bearer selection (Master Cell Group (MCG),  bearer, Secondary Cell Group (SCG) bearer, Split bearer),   ...
