Linux login administrator account password

I. Virtual machine selection bridge mode

1. Open the editor in Edit-Virtual Network Editor, as shown in the following two figures, select vmnet0, select bridge in the following type, that is, bridge, network card do not select automatic (automatic), manually select the actual network card name for your current host, and then click Apply, OK.

Note that the default setting of the virtual machine is automatic bridging. Notebooks generally have 2 network cards. Be sure to bridge to the network card that is currently on the Internet to avoid errors!

How to check the network card that is surfing the Internet? Check your PC's adapter settings and find your Internet card

2. Virtual machine select bridge mode (custom vmnet0), OK.

Second, manually set static ip in the virtual machine

Check the IP address of Linux.

centos6 command: ifconfig

centos7 command: ip addr

Remember: record the name of the network card, this machine is ens33

Look at the IP of the host window.

win+r --cmd ----ipconfig/all

IP: 192.168.3.9

Step 1: Enter the terminal/etc/sysconfig/network-scripts/directory

Step 2: Modify ifcfg-eth(xxx) file

vim ifcfg-eth0

ps: ifcfg-ens33 of centos7 is the same as just recorded

If you see that your linux distribution has a different device name than mine, don't ask why, change is hope! (-)I didn't say it was ubuntu, why did I say centos? We all know that redhat is the most widely used linux distribution in enterprise applications, but redhat has to be charged, why? This is a good job! Smaller companies probably use centos the most. Why centos? This is because redhat centos to the acquisition, centos is now called community version, redhat in the service, is the first service to the community version centos, through community feedback, when the technology is mature enough, will add new technology or services to redhat, so centos is actually indirect in the use of radhat! This is the way, of course, you can go to Baidu to understand, not to mention let you Google, in heaven is really a little powerless to surf the Internet, you know good! Haha...

Do not cause conflicts like host ip gateway=192.168.230.1 #default gateway is OK like physical host netmask=255.255.255.0 #subnet mask is OK like physical host dns1=8.8.8.8 #dns, just write Google's address.
