1.配置监听

listener.ora

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = oracle路径\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:oracle路径\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME =oracle路径\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)

)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ip地址)(PORT = 1521))
)
)

红色部分为新加部分,然后重启oracle监听即可

为了安全性考虑，可以开启防火墙，开放端口/程序（主要是ftp）给指定ip访问。查看本地电脑外网ip(百度搜索‘ip’即可)
