Oracle修改数据库监听的端口号
先停止监听
[oracle@oracle admin]$ lsnrctl stop

修改listener.ora配置文件，将端口号1521修改为1526
[oracle@oracle admin]$ cat listener.ora
# listener.ora Network Configuration File: /oracle/11g/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.101)(PORT = 1526))
)
)
ADR_BASE_LISTENER = /oracle/11g
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl1)
(ORACLE_HOME = /oracle/11g/product/11.2.0/dbhome_1)
(SID_NAME =orcl)
)
)
登录并修改local_listener参数
[oracle@oracle admin]$ sqlplus / as sysdba
SQL> show parameter local_listener; ##查出来应该是空值
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string
##修改参数
SQL> alter system set local_listener="(address = (protocol = tcp)(host = 10.10.10.101)(port = 1526))";
System altered.
SQL> show parameter local_listener;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (address = (protocol = tcp)(ho
st = 10.10.10.101)(port = 1526
))
启动监听，查看状态
[oracle@oracle admin]$ lsnrctl start
[oracle@oracle admin]$ lsnrctl status

检查端口
[oracle@oracle admin]$ netstat -tlunp |grep 1521 ##1521不存在了
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
[oracle@oracle admin]$
[oracle@oracle admin]$ netstat -tlunp |grep 1526 ##改到1526上了
(Not all processes could be identified, non-owned process info

远程连接，注意方通1526端口的防火墙限制
[oracle@mysql-master-1003306 admin]$ cat tnsnames.ora
orcl1 =

[oracle@mysql-master-1003306 admin]$ tnsping orcl1
