So many great points already made.
Don't be afraid to ask your team 'what can I do to make your work easier?' Your staff will probably know the systems better than you at the moment, and so they'll also be aware of the faults in the systems.
Have your team's backs. Protect them from unreasonable management. That doesn't mean being argumentative, but it does mean being assertive to your bosses about what is and isn't possible, and what is and isn't fair. The worst bosses I've had have been those who have focussed on pleasing their manager, at the expense of their team.
Don't worry about being liked. Be fair. Fir example, if your place of work has a code of conduct or dress code etc, enforce it with everyone, every time. You don't need to be heavy handed, but an impromptu quiet word out of earshot of others.
Lead by example - never ask a team member to do something you would not be willing to do yourself. Where possible, do it yourself at times where no-one else is willing/able - or if they are hesitant, work alongside them the first time.
In a nutshell, focus on being someone who makes the lives of your team easier, not harder.
