前提回现

修改了主机名,由hyldb修改为hyl。

问题现象

配置监听,警告提示,如下所示:

配置监听_1521端口占用问题_第1张图片

解决方法

1、检查1521端口

[root@hyl ~]# netstat -a

--查看端口占用情况,查明1521端口并未被占用

unix  3      [ ]         STREAM     CONNECTED     4472    

2、检查hosts

[root@hyl ~]# vi /etc/hosts

修改前:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1       hyldb localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.56.101  hyl

~

~

~

--由于修改了主机名(hyldb修改为hyl),将之前配置中hyldb内容删除

修改为:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1       localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.56.101  hyl

~

~

~

~

 

3、检查network

# vi /etc/sysconfig/network

--确认添加了如下信息

NETWORKING=yes

HOSTNAME=hyl

 

4、检查ipv6是否关闭

 

查看ipv6状态,查看其是否被关闭

[root@hyl ~]# lsmod |grep ipv6

ipv6                  435105  17 cnic

xfrm_nalgo             43333  1 ipv6

 

补充:关闭ipv6方法

1) # vim /etc/modprobe.conf
在其中加入下面这一行,

install ipv6 /bin/true

保存并退出。

2)# vim /etc/sysconfig/network
在其中加入下面配置项:

NETWORKING_IPV6=no
IPV6INIT=no


 

重启后查询:

[root@hyl ~]# lsmod |grep ipv6

--没有显示ipv6相关信息,表示ipv6已经关闭

 

5、重启系统后,查看hostname

[root@hyl ~]# hostname

--查询主机名

hyl

 

6、再次执行netca

配置监听、dbca建库成功。
