修改oracle数据库监听端口号

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

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
