今天安装oracle数据库的时候一直报00600的错误，都搞崩溃了，最后才发现错的好离谱
主机名当时修改的是hhhh
-
@hhhh~]$dbca
-

（注：图片当时忘截了，这是后期在网上看到的图，报错都是一样的)
[root@hhhh ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=hhhh
[root@hhhh ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
::1 localhost6.localdomain6 localhost6
192.168.200.12 hhh
刚开始还没发现错误，百度搜好多发现网友的原因都是:/etc/hosts文件错误，
最后终于发现hosts文件主机名少了一个h，，，，，好无语。
[root@hhhh ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
::1 localhost6.localdomain6 localhost6
192.168.200.12 hhhh

"/etc/hosts" 5L, 190C written
问题解决。
在此劝诫其他朋友，给主机命名最好起个有意义一点的，避免再发生类似错误。
