[Lotr] What did Sauron do as the necromancer?

Did he raise any dead? I know that you cant bring back the souls of the dead, as they have left the world, but you can controll souls that are stuck in middle earth. Did he just controll them, or did he raise any soulless zombies, just corpses? Or was it just a name he picked to scare people?

Dead, no.  He's the necromancer because he bends (but doesn't break) Middle Earth's rules of mortality.  Even the ringwraiths aren't technically undead, since they never actually died; they simply had their lifespans stretched far beyond natural limits.
