Linux 错误：111：连接被拒绝 LSNRCTL

  • 772

我在启动监听器时遇到问题，我使用的是 Centos 6.5 和 Oracle 12cR1。

数据库已成功安装。

现在我的问题是当我启动我的监听器时，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...
Service "tuts" has 1 instance(s).
Instance "tuts", status UNKNOWN, has 1 handler(s) for this service...
 Handler(s):
  "DEDICATED" established:0 refused:0
     LOCAL SERVER
 The command completed successfully

我的主机名是gaurav

hosts所以我在文件中创建一个条目

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
 192.168.1.1        gaurav      oracle

另外，我创建了一个 listener.ora 文件，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 ping 我的主机gaurav。

谁能帮我解决这个问题？

    对我来说，您似乎没有启动侦听器，但它已启动。您的问题似乎是 tcp 连接而不是 ipc。所以监听器正在运行，你无法使用 tcp 访问它。使用telnet gaurav 1521

    如果 telnet 没有提供连接，则防火墙正在阻止您。停止/编辑防火墙。
