Append the following lines of script to the end of the automatic script in ~/.bashrc (corresponding to the root user, which is the /root/.bashrc file).

# Auto add env parameter $PROMPT_COMMAND when use non-Linux tty login by ssh.
if [ "$SSH_CONNECTION" != '' -a "$TERM" != 'linux' ]; then
declare -a HOSTIP
HOSTIP=`echo $SSH_CONNECTION |awk '{print $3}'`
export PROMPT_COMMAND='echo -ne "\033]0;${USER}@$HOSTIP:[${HOSTNAME%%.*}]:${PWD/#$HOME/~} \007"'
be

Save and log out and log back in.
