export的declare

原[root@localhost ~]# 被修改成[root@mta54 ~]#  怎么改回来啊？
[root@mta54 ~]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=localhost

[root@mta54 ~]# cat /etc/hosts
# 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

发现都正常的。

[root@mta54 ~]# export
declare -x CLASSPATH=".:/usr/local/jdk1.6.0_38/lib/dt.jar:/usr/local/jdk1.6.0_38/lib/tools.jar"
declare -x G_BROKEN_FILENAMES="1"
declare -x HISTSIZE="1000"
declare -x HOME="/root"
declare -x HOSTNAME="mta54.customer.shangpin.com"

发现是这边的原因，但是我输入命令declare -x HOSTNAME="localhost.localdomain" 还是无效。烦请各位大哥救助下。。
