This article introduces the relevant knowledge of "how RHEL7 configures ip addresses". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Graphical interface configuration method

Click on the wired connection in the upper right corner of the desktop, and select configure ens33

Enter ip address, mask, DNS, gateway, etc.

Then select the startup to ok.

In this way, the network configuration is complete!

By modifying the configuration file

Modify the configuration ip by modifying the ifcfg-ens33 configuration file

[root@localhost] # vim / etc/sysconfig/network-scripts/ifcfg-ens33 TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=dhcpDEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6INIT=yesIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_FAILURE_FATAL=noIPV6_ADDR_GEN_MODE=stable-privacyNAME=ens33UUID=96a5f670-6b15-4711Muaf6eMur92aa92e1c66bDEVICEroomens33ONBOOTRANNON ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ "/ etc/sysconfig/network-scripts/ifcfg-ens33" 15L 279C

Change BOOTPROTO to static

Change ONBOOT=no to ONBOOT=yes

Add the IPADDR NETMASK GATEWAY DNS1 field as follows:

[root@localhost] # cat / etc/sysconfig/network-scripts/ifcfg-ens33 TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=staticDEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6INIT=yesIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_FAILURE_FATAL=noIPV6_ADDR_GEN_MODE=stable-privacyNAME=ens33UUID=96a5f670-6b15-4711-af6e-92aa92e1c66bDEVICE=ens33ONBOOT=yesIPADDR=172.16.1.115NETMASK=255.255.255.0GATEWAY=172.16.1.254DNS1=8.8.8.8

So restart the network card on it!

[root@localhost ~] # systemctl restart network

Use tool configuration

Enter the following command to specify the ip mask

[root@localhost ~] # nmcli connection modify ens33 ipv4.method manual ipv4.address 172.16.1.120 Universe 24 connection.autoconnect yes

Restart the network card
