Linux Setup Network

Linux setup network.

The following actions are based on the NAT mode,

1. Automatically obtain an IP address in the state after login

   # dhclient

2. View your IP

# IP Addr

The Linux operating system is case-sensitive, and you can see that there are two IP addresses on this machine. The first address, 127.0.0.1, is a loopback address, and the network card name is lo, which is used for communication. The second address is 192.168.183.129 is automatically obtained automatically just the IP address, Ens33 is the name of the network card.

3. Press CTRL and ALT at the same time to release your mouse, then click "Edit" in the upper left corner of the VMware Virtual Machine menu bar, select "Virtual Network Editor", pop up the following interface

Check VMnet8 (NAT mode), below you can see the subnet IP 192.168.183.0, the subnet mask is 255.255.255.0, click on the "Nat settings" button on the right, pop up the following interface

In this interface, we see that the gateway is 192.168.183.2, please remember this gateway address, a

Then test if CentOS7 can be networked.

Next we need to manually set the IP address for the Linux system

# Vi/etc/sysconfig/network-script/ifcfg-ens33, then enter, enter the NIC configuration file,

We can use, up, down, left, right, arrow keys to move the cursor, but not directly to modify the file content, you need to press the letter I key, need to modify the content has, speak Onboot=no, changed to Onboot=yes, will bootproto=dhcp changed to bootproto= Static

and add a few lines of characters

ipaddr=192.168.183.128

netmask=255.255.255.0

gateway=192.168.183.2

dns1=119.29.29.29

Onboot is set to Yes to indicate that the NIC is started with the system, Bootproto is used to set the startup type of the network card, DHCP indicates that the IP address is automatically obtained, and static indicates that the IP address is set manually. IPAddr Specify the IP address, netmask Specify the subnet mask, gateway to specify the gateways, DNS1 specify the DNS IP address for the Internet, this 119.29.29.29 is a public DNS provided by the domestic Dnspod company, after the modification, click "ESC", Then press "Shift+enter" to enter ": Wq" and enter, exit the document, and then restart the network service

# systemctl Restart Network.service

Then look at the IP address

# IP Addr

If it's correct, ping the test network.

All the steps on these thank you!!!
