安装Oracle 11gR2，报错：[INS-06101] IP address of localhost could not be determined

出现这种错误是因为主机名和/etc/hosts 文件不一致，只需要把主机名和其IP 写入/etc/hosts 文件，就ok了。

[root@localhost~]# cat /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=localhost.localdomain

[root@localhost~]# cat /etc/hosts

# Do not removethe following line, or various programs

# that requirenetwork functionality will fail.

127.0.0.1localhost

这里我们修改一下主机名，Linux 下修改/etc/sysconfig/network 里的hostname 需要重启系统才能生效。

修改network 文件之外，再使用hostname 命令指定一下主机名，就不用重启OS了。

[root@localhost~]# cat /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=dave

[root@localhost ~]# hostname

localhost

[root@localhost ~]# hostname dave

[root@localhost ~]# hostname

dave

[root@localhost ~]# cat /etc/hosts

# Do not remove the following line, orvarious programs

# that require network functionality willfail.

127.0.0.1 localhost

192.168.3.222 dave
