问题分析

1./etc/hosts文件中的IP和主机名不一致
2.listener.ora中监听的主机非当前主机

解决方案

修改listener.ora文件把ip改为当前主机或127.0.0.1

vim  /opt/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

改为

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
        (GLOBAL_DBNAME = orcl)
        (ORACLE_HOME = /opt/oracle/product/11.2.0/dbhome_1)
        (SID_NAME = orcl)
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
  )
