【VMware】
设置“网络适配器”，修改“网络连接”为“桥接模式”，即直接连接物理网络。
【Ubuntu】
以Ubuntu18.04为例。
修改network-manager文件，配置相关网络参数。
root@ubuntu:~# cd /etc/netplan/ ; ls
01-network-manager-all.yaml
root@ubuntu:/etc/netplan# cp 01-network-manager-all.yaml 01-network-manager-all.yaml.ori
root@ubuntu:/etc/netplan# vim 01-network-manager-all.yaml
root@ubuntu:/etc/netplan# cat 01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:

renderer: NetworkManager
ethernets:
ens33:
dhcp4: no
dhcp6: no

gateway4: 192.168.1.1
nameservers:
addresses: [192.168.1.1, 8.8.8.8, 8.8.4.4]具体修改内容如下。

以CentOS7为例。
修改系统对应网络接口文件（一般为/etc/sysconfig/network-scripts/目录下的第一个文件），配置相关网络参数。
[root@centos ~]# cd /etc/sysconfig/network-scripts/ ; ls

①VMware网络适配器选择桥接模式。
②修改系统文件保持谨慎最好先备份再修改。
③设置的静态IP须为当前网络中的有效IP（既在网络范围内又不与其他主机IP冲突）否则配置无法生效。
