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
[[email protected] ~]$ lsnrctl start

6、查看系统状态
[[email protected] ~]$ 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)

已经开启10001端口号
7、验证登陆
[[email protected] ~]$ sqlplus / as [email protected]:10001:pu
