服务器两个域名一个ip做两个网站网站如何优化排名
需求
实验
vmware网络配置（企业内部一般为ESXI）
这样服务器虚拟机使用192.168.200.X网段才能与用户侧互通
vmware虚拟机配置（DHCP服务器网络配置）
- 打开网络管理页面
nmtui
-
重置一下网络连接（重启网卡）
-
检查IP地址
ip addr
清空交换机所有配置信息并重启
#
quit
reset saved-configuration
reboot
中继交换机（核心交换机）网络配置
- 根据规划，划分vlan 10-18、20、200
#
sysname DHCPrelay
vlan batch 10 to 18 20 200
- 配置vlan接口地址（网关）
#
int vlanif 10
ip add 192.168.10.254 24#
int vlanif 11
ip add 192.168.11.254 24#
int vlanif 12
ip add 192.168.12.254 24#
int vlanif 13
ip add 192.168.13.254 24#
int vlanif 14
ip add 192.168.14.254 24#
int vlanif 15
ip add 192.168.15.254 24#
int vlanif 16
ip add 192.168.16.254 24#
int vlanif 17
ip add 192.168.17.254 24#
int vlanif 18
ip add 192.168.18.254 24#
int vlanif 20
ip add 192.168.20.254 24#
int vlanif 200
ip add 192.168.200.254 24

-
在服务器交接机e 0/0/1处抓包
发现PC10 的DHCP广播报文已到达此接口
-
ping命令测试（给PC10手动设置IP 192.168.10.99）
以上可以看出只有 ARP报文，报文无法到达192.168.10.254(中继交换机vlanif 10 接口地址) -
再次用ping命令测试（给PC10手动设置IP 192.168.10.99）
测试前，配置mac-vlan
#
vlan 10
mac-vlan mac-address 5489-9884-1796#
int g 0/0/10
mac-vlan enable
正常通信
配置DHCP中继
#
int vlanif 10
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 11
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 12
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 13
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 14
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 15
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 16
dhcp select relay
dhcp relay server-ip 192.168.200.253#
int vlanif 17
dhcp select relay
dhcp relay server-ip 192.168.200.253
quit#
int vlanif 18
dhcp select relay
dhcp relay server-ip 192.168.200.253
PC10正常获取IP
PC11无法正常获取IP（因为DHCP中继是做在vlanif接口上的，而PC11无确定Vlan）
把PC10接入vlan11 的交接机获取的IP依然是vlan10 (MAC-Vlan)
与服务器正常通信

核心交接机全部配置-备份还原
华为交换机备份配置文件和还原配置文件的方法有多种，以下是一些常见的方法：
备份配置文件
使用命令行界面：
通过display current-configuration命令查看当前配置。
将显示的信息拷贝到一个TXT文本文件中，从而备份配置文件到维护终端的硬盘中。
需要注意的是，如果现实界面中有换行的命令，需要删除换行，否则当使用制作的TXT文本恢复配置时，换行的配置将无法恢复。
使用图形用户界面（GUI）：
打开GUI，登录到交换机的管理界面1。
导航到配置管理页面1。
选择要保存的配置文件，并点击保存按钮，将配置保存到指定的位置1。
使用FTP备份：
备份配置文件到交换机的flash中。
在交换机上开启FTP服务器，并配置FTP用户。
在PC端通过FTP客户端与设备建立FTP连接，并下载备份的配置文件。
还原配置文件
通过命令行界面：
使用copy命令将备份的配置文件（如TXT文本文件）恢复到交换机中。但直接通过命令行界面恢复TXT文本文件可能不是直接支持的，通常需要将文件上传到交换机的flash中，然后通过命令来加载。
使用图形用户界面（GUI）：
登录到交换机的GUI管理界面
导航到配置管理页面或相关的恢复配置选项。
选择要恢复的配置文件，并执行恢复操作。
恢复出厂设置：
登录到交换机的命令行界面。
进入系统配置模式
使用reset factory-configuration命令来恢复出厂设置。这同样会清除所有的业务配置和数据文件。
下面使用ssh及sftp方式演示：
- 登陆ssh
#
quit
dir
- 保存配置文件
#
quit
save all
-
登陆sftp
-
下载
本以为大功告成，结果…
于是尝试ftp(需要在aaa：local-user下配置)
#
ftp server enable
#
aaa
local-user admin service-type ftp
local-user admin ftp-directory flash:/
