CentOS7 network configuration under VMware virtual machine (host wireless Internet access)

This is the first time I used the CentOS7 system and I encountered many problems when doing network configuration. I wrote this blog to record the solution to the problem. I welcome your comments.

1. Virtual Machine Settings

At the top of the VMware interface, select Virtual Machine -> Settings: Change the network connection to bridge mode, as shown below:

2. Check the host DNS address

Win+R, enter cmd, start the command line interface, enter ipconfig/all, and check the host DNS server address, as shown in the following figure:

Note that since this machine is connected to the Internet wirelessly, this is the DNS server address of the wireless LAN. Write down this address as it will be useful later.

3. Modify the CentOS7 network configuration file

1. Open the terminal in CentOS7 and enter cd /etc/sysconfig/network-scripts/

2. Enter vi ifcfg-ens33 to open the network configuration file ifcfg-ens33, as shown in the following figure:

The content of the configuration file is as follows:

TYPE=Ethernet # Network card type: Ethernet PROXY_METHOD=none # Proxy mode: Disabled BROWSER_ONLY=no # Only browser: No BOOTPROTO=dhcp # Boot protocol of network card: DHCP
DEFROUTE=yes # Default route: yesIPV4_FAILURE_FATAL=no # Disable IPV4 fatal error detection: noIPV6INIT=yes # Whether IPV6 is automatically initialized: yesIPV6_AUTOCONF=yes # Whether IPV6 is automatically configured: yesIPV6_DEFROUTE=yes # Can IPV6 be the default route: yesIPV6_FAILURE_FATAL=no # Disable IPV6 fatal error detection: noIPV6_ADDR_GEN_MODE=stable-privacy # IPV6 address generation model: stable-privacy 
NAME=ens33 # Network card physical device name UUID=42773503-99ed-443f-a957-66dbc1258347 # Universal unique identifier DEVICE=ens33 # Network card device name ONBOOT=no # Whether to start the computer. You can use systemctl restart network to restart the network.

3. Modify ONBOOT=yes and add DNS1=192.168.31.1. Set this DNS address to the local DNS address (the address you wrote down earlier)

Enter Esc :wq! to exit, as shown in the following figure:

Note: If the user does not have sufficient permissions, an error message will be displayed when saving. It is recommended to log in to the root account.

4. Enter systemctl restart network to restart the network. If no information is prompted, it means that the network restart is successful, as shown in the following figure:

At this point, all settings are completed and you can surf the Internet by opening the browser.
