一、修改默認(rèn)端口1521

1、查看數(shù)據(jù)庫(kù)監(jiān)聽(tīng)狀態(tài)，并獲取監(jiān)聽(tīng)文件路徑

[root@localhost admin]# lsnrctl status

2、先停止監(jiān)聽(tīng)

[root@localhost admin]# lsnrctl stop

LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 18-MAR-2020 08:59:00

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))
The command completed successfully

3、修改listener.ora 文件里面的port設(shè)置

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=2345)))
(DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521)))

4、重啟監(jiān)聽(tīng)，可看到已修改

lsnrctl start

5、修改初始化參數(shù)local_listener

SQL> alter system set local_listener="(address = (protocol = tcp)(host = 59.42.192.216)(port = 3306))";
System altered.

至此修改完成
