to start tmux on login add the following to your ~/.bashrc

# Start Tmux by default
# If not running interactively, do not do anything
if command -v tmux>/dev/null; then
  [[ ! $TERM =~ screen ]] && [ -z $TMUX ] && exec tmux

to automatically attach to last session or create a new if none available extend your ~/.bashrc and ~/.tmux.conf with the following

~/.bashrc

# Start Tmux by default
# If not running interactively, do not do anything
if command -v tmux>/dev/null; then
  [[ ! $TERM =~ screen ]] && [ -z $TMUX ] && exec tmux attach
fi

~/.tmux.conf

# if run as "tmux attach", create a session if one does not already exist
new-session -n $HOST
