<pre>
第一
vim /etc/sysconfig/network
HOSTNAME=frgdb_guanwang
第二
hostname frgdb_guanwang && export HOSTNAME=frgdb_guanwang

#把有HOSTNAME关键字的那整行替换了
sed -i '/HOSTNAME/ s/.*/HOSTNAME=notuse/g' /etc/sysconfig/network && hostname notuse &&export HOSTNAME=notuse

以下为针对gentoo
localhost ~ #vim /etc/conf.d/hostname
hostname=”evanpc”
localhost ~ #hostname evanpc
localhost ~ #export HOSTNAME=frgdb_guanwang

要先exit 然后再login就行了

ServerIndexno=3,

/bin/sed -i ‘/ServerIndex/ s/.*/ServerIndex=’${ServerIndexno}’/’ World.txt
</pre>

=Ubuntu/Debian=
==修改/etc/hosts==
==修改/etc/hostname==


hostname myvm 临时修改一下。当下次重启系统，则真正生效
