You can use the preferred leader election tool to move the leadership.

AFAIK, the simplest way will be to shutdown your 2 others brokers after you
restarted your broker 1, which will force your topics to have your broker 1
as leader since it's the only one available, and then restart your brokers
2 and 3
But I can't really see why you want your leaders on broker 1...
i have 3 broker,when i restart a broker 1,then 1 can not as leader.i want to
know how i can recover broker 1 as a leader.
thanks,
