Another way you could do it is by scripting this into your Gamamode:

pawn Code:

if(strcmp(cmd,"/restart",true)==0)
{
  if(IsPlayerAdmin = 1)
  {
    SendRconCommand("gmx");
    return 1;  
  }
  else
  {
    SendClientMessage(playerid,a color,"BAD NOOB! You no restart server! Go sit in corner");
    SetPlayerHealth(playerid, 0);
    return 1;
  }
}

then all you gotta do is type your rcon login command and do /restart
