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。
