CentOS 下永久修改主机名

使用hostname –v  your.hostname 修改只是临时性的，重启后无效。

修改步骤：

1. # vi   /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

#HOSTNAME=localhost.localdomain

HOSTNAME=yourhostname

2. # vi  /etc/hosts

# Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost yourhostname
