Linux错误: 111:连接拒绝LSNRCTL
Linux错误: 111:连接拒绝LSNRCTL
提问于 2014-06-04 16:57:53
我在启动侦听器时遇到了问题，我正在使用CentOS6.5和Oracle 12cR1。
数据库已成功安装。
现在我的问题是，当我启动侦听器时，会显示以下错误：
LSNRCTL> service
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=gaurav)(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 111: Connection refused
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
Services Summary...

Instance "tuts", status UNKNOWN, has 1 handler(s) for this service...
Handler(s):

LOCAL SERVER
The command completed successfully我的主机名是gaurav
所以我在hosts文件中创建了一个条目
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.1 gaurav oracle此外，我还创建了一个listener.ora文件，其内容如下：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =gaurav)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
sid_list_listener=
(sid_list=
(sid_desc=
(oracle-home=/home/oracle/app/oracle/product/12.1.0/dbhome_1)
(sid_name=tuts)))我能够平平我的主机gaurav。
有人能帮我解决这个问题吗？

在我看来，你似乎没有启动侦听器，但它已经启动了。您的问题似乎是tcp连接，而不是ipc。因此，侦听器正在运行，您无法使用tcp访问它。使用telnet gaurav 1521进行测试
如果telnet不提供连接，防火墙就会阻塞您。停止/编辑防火墙。
