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。
