我在 Centos 6.3 上安装了最新版本的 Oracle 11g。但由于某种原因，我无法连接到 SQL plus。这是 listener.ora 的内容：

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.104)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle

我在 shell 中输入：

[oracle@localhost bin]$ ./lsnrctl start

然后我尝试启动 SQL 加上这个：

[oracle@localhost bin]$ ./sqlplus sys@oracle AS SYSDBA

确保 $TNS_ADMIN 指向 tnsnames.ora 和 sqlnet.ora 所在的目录。
