1. Vmvare设置 “编辑->虚拟机网络编辑”2. 新建一个虚拟机并给它设置网卡3. 配置eth0网卡为静态IP `vim /etc/sysconfig/network-scripts/ifcfg-eth0`4、测试1. Vmvare设置 “编辑->虚拟机网络编辑”
这里设置了3个虚拟网络(两个主机模式，这两个网络其实都没用到，然后配置了一个NAT模式，默认是动态IP，可以通过DHCP配置修改动态变更范围、时间等，后续就把它改为静态IP)
如图可以看出这就是动态IP

3. 配置eth0网卡为静态IPvim /etc/sysconfig/network-scripts/ifcfg-eth0
# 默认是如下动态IP (dhcp)配置BOOTPROTO=dhcpONBOOT=yes DEVICE=eth0
现在把eth0改为静态IP，注意设置的静态IP地址 ，可取192.168.72.0~192.168.72.255 前缀同网关，192.168.72.0一般是子网IP，192.168.72.2是网关，192.168.72.255是广播IP，故静态IP的末位不能是0，2，255
DEVICE=eth0OXY_METHOD="none" BROWSER_ONLY="no" BOOTPROTO="static" # 使用静态IP地址，默认为dhcpIPADDR="192.168.72.128"# 设置的静态IP地址 ，可取192.168.72.0~192.168.72.255 前缀同网关，192.168.72.0一般是子网IP，192.168.72.2是网关，192.168.72.255是广播IP，故静态IP的末位不能是0，2，255NETMASK="255.255.255.0" # 子网掩码 GATEWAY="192.168.72.2"# 网关地址 就是上面说的那个地址DNS1="114.114.114.114"# DNS服务器,不用改DEFROUTE="yes"IPV4_FAILURE_FATAL="no"IPV6INIT="yes"IPV6_AUTOCONF="yes"IPV6_DEFROUTE="yes"IPV6_FAILURE_FATAL="no" IPV6_ADDR_GEN_MODE="stable-privacy"UUID="95b614cd-79b0-4755-b08d-99f1cca7271b" #随便ONBOOT="yes"
4、测试
使用nmcli网卡管理工具查看各网卡状态，
[root@node-1 ~]# nmcli device statusDEVICE TYPESTATE CONNECTIONeth0 ethernet 已连接 System eth0eth1 ethernet 已断开 -- docker0bridge 未托管 -- loloopback 未托管 --
可以ifconfig看到eth1的TX ,RX数据确实是有问题的，仅有一点输出流量，且 ifconfig eth0 down 之后ping 是不通的了
