Can`t start oracle instance 11gR2 on Ubuntu 10.4

Question

I noticed something that some diretories are named using my hostname (phoenixbai) while others use localhost.
e.g.
./cdata/localhost
./localhost_ora11g
./localhost_ora11g/sysman/emd/upload/localhost_host_host_configuration_old
./oc4j/j2ee/OC4J_DBConsole_localhost_ora11g
./log/phoenixbai （DIR）
when I rename localhost in ./oc4j/j2ee/OC4J_DBConsole_localhost_ora11g, ./localhost_ora11g with phoenixbai, i can start the oracle instance.
but still, I can`t start lsnrctl & emctl. here is the listener.ora, tnsnames.ora, and /etc/hosts details:
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
      (ADDRESS = (PROTOCOL = TCP)(HOST = phoenixbai)(PORT = 1522))
ADR_BASE_LISTENER = /u01/oracle
ORA11G =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = phoenixbai)(PORT = 1522))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora11g)
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
LISTENER_ORA11G =
  (ADDRESS = (PROTOCOL = TCP)(HOST = phoenixbai)(PORT = 1522))

127.0.0.1     localhost     localhost
#127.0.0.1       phoenixbai      phoenixbai

# The following lines are desirable for IPv6 capable hosts

fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
