oracle默认端口号是1521.很容易就被黑客扫描到然后天天惦记你的数据库 所以修改默认端口号就很有必要了 1、首先查看监听状态 lsnrctl status 2、关闭监听 lsnrctl stop 3、修改监听文件1521====10001 SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (ORACLE_H

oracle默认端口号是1521.很容易就被黑客扫描到然后天天惦记你的数据库

所以修改默认端口号就很有必要了

1、首先查看监听状态

lsnrctl status

2、关闭监听

lsnrctl stop

3、修改监听文件1521====>10001

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME = /u01/11g)
      (SID_NAME = pu)
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = target)(PORT = 10001))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )


ADR_BASE_LISTENER = /u01/oracle


4、登陆数据库修改local_listenner



SQL> show parameter local_listener


NAME                                 TYPE
------------------------------------ ----------------------
VALUE
------------------------------
local_listener                       string


VALUES值为空


修改local_listener参数

SQL> show parameter local_liste


NAME                                 TYPE
------------------------------------ ----------------------
VALUE
------------------------------
local_listener                       string


SQL> alter system set local_listener="(address = (protocol = tcp)(host = target)
  2  (port = 10001))";


System altered.


SQL> show parameter local_lis


NAME                                 TYPE
------------------------------------ ----------------------
VALUE
------------------------------
local_listener                       string
(address = (protocol = tcp)(ho
st = target)
(port = 10001))


5、启动监听

[oracle@target ~]$ lsnrctl start

STATUS of the LISTENER

  Instance "pu", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully

6、查看系统状态

[oracle@target ~]$ netstat -ano|grep 10001
tcp        0      0 192.168.6.152:26082         192.168.6.152:10001         ESTABLISHED off (0.00/0/0)
tcp        0      0 :::10001                    :::*                        LISTEN      off (0.00/0/0)
tcp        0      0 ::ffff:192.168.6.152:10001  ::ffff:192.168.6.152:26082  ESTABLISHED keepalive (7193.37/0/0)

已经开启10001端口号


7、验证登陆

[oracle@target ~]$ sqlplus / as sysdba@target:10001:pu
