An example of implementing static IP login for a virtual machine

Environment: laptop + home WIFI + company WIFI + VMware + CentOS6.8 + Xshell

Problem description: When I first learned Linux, I installed a virtual machine (single network card) on my laptop and wanted to implement Linux at home and in the company They can connect to the Internet wirelessly, but they don’t want to manually enter the IP to log in to Xshell every time after the Internet location changes.

Solution: Add a network card (eth1), set eth1 to VMnet1 (host-only mode) for Xshell login, and the original network card eth0 is VMnet8 (NAT mode)

Implementation Method:

Open the VM's "Virtual Network Editor", check the VMnet1 subnet address, and manually change it to 11.11.11.0

Start Linux and log in as root.

Modify the eth0 configuration file

# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:0C:29:97:06:BC
TYPE=Ethernet
UUID=24e72ebf-5682-4a8f-87a4-6b53b39a5e0b
ONBOOT=yes #开机启用网卡
NM_CONTROLLED=yes
BOOTPROTO=dhcp #确保启用DHCP服务来自动获取IP

Modify the eth1 configuration file

# vim /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1 #注意HWADDR（MAC地址）和UUID（通用唯一识别码Universally Unique Identifier）不能与其他网卡重复
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static #静态IP用于xshell远程登录
IPADDR=11.11.11.68  #VMnet1的子网是30段
NETMASK=255.255.255.0 #GATEWAY=11.11.11.1 我的错误点：网卡eth1不能加网关

After the configuration is completed, restart the network service and check the network connection Situation

#service network restart

#ping www.qq.com

Ping successfully proves that you can connect to the external network, this solution is feasible.
