Foreword:
Virtual machine: VMware16
System: centOS7
1. Problem
Every time I open VMware on my computer and enter Linux, I find that sometimes the IP will change, causing problems in transferring files or remote connections. It is relatively troublesome to change other files every time I change the IP.
2. Reasons
Because the ip of the virtual machine is dynamically allocated , it is possibleThere are several reasons leading to its change:
- The network the host is connected to is different. For example, last time it was connected to the hotspot of your mobile phone, this time it is connected to a network cable;
- Shut down the host and restart it;
- Uninstall VMware and re-import the virtual machine.
3. Solution (fixed IP address)
(1) Preparation work
1. Query the virtual machine IP address
# ifconfig
2. Query the gateway ip
Edit One>Virtual Network Compiler One>Change Settings One>Select at the topNAT mode, select at the bottom NAT settingsone>Gateway IP
(2) Fixed IP
- Location 1>Computer
- Enter the following location
etc/sysconfig/network-scripts
- Right-click to enter the terminal and open the virtual machine network card configuration file ifcfg-ens33
# vim ifcfg-ens33
- Changedhcp to static and let the IP be assigned The rules are static and never change
BOOTPROTO="static"
- Configure the virtual machine IP address, gateway IP, and domain name resolution server at the end of the network card configuration file.
IPADDR="own IP address"
GATEWAY="own gateway IP"NAS1="Same as gateway IP"
- Exit editing and save and exit
Esc one>:wq
- Restart the network card
# systemctl restart network
(3) Check whether the network is connected
1. View on this machine
> ping the IP of the virtual machine
2.Virtual machine viewing
#ping local IP
(4) Selection of local IP
1. Cable network card
2. Wireless network card
3. Not using VMware Network
