【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:
        version: 2
        renderer: NetworkManager
        ethernets:
                ens33:
                        dhcp4: no
                        dhcp6: no
                        addresses: [***.***.***.28/24]
                        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。

root@ubuntu:/etc/netplan# diff 01-network-manager-all.yaml 01-network-manager-all.yaml.ori 
3,12c3,4
<         version: 2

<                         dhcp6: no
<                         addresses: [***.***.***.28/24]
<                         gateway4: 192.168.1.1
<                         nameservers:

启用配置。

【CentOS】

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
ifcfg-ens33  ifdown-ib    ifdown-ppp       ifdown-tunnel  ifup-ib    ifup-plusb   ifup-Team         network-functions

具体修改内容如下。

[root@centos network-scripts]# diff ifcfg-ens33 ifcfg-ens33.ori

【注意事项】

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。
