First, is having peace with God. Second, its having peace with the body of Jesus Christ. (Ephes 4:1-3) tells us very clearly that if we are to walk" worthy of the vocation wherewith ye are called," we must be " endeavoring to keep the unity of the Spirit in the bond of peace." A third thing that makes you a peacemaker is reconciliation. A key element of peacekeeping is bringing the gospel of peace to other people so that they in turn might have peace with God.
