Instead, I would like a series of specific nmcli commands that can be entered into the terminal manually, and which also can make it easier to design a bash script later. For example, the UUID line would require special handling in a script that simply copied in the config file and rebooted the machine. I am imagining lots of overly complicated scripting if we stay with the config file approach shown below. There are a number of options/methods available to do this outlined below. The four step process shown below DOES effectively configure static IP networking.īut the process below relies on config files, which might not easily lend themselves to an automated scripted approach later. This guide details howto configure a static IP on CentOS 7 or 8 on an operating system installed without a GUI. PREFIX=24 #here you can use netmask if you like, NETMASK=255.255.255.0įinally, restart the network service to insecure change takes effect.What specific sequence of nmcli commands can be used to effectively configure static IP networking in CentOS 7? Refer to the networking configuration page in the customer portal for your exact. You need to manually configure these advanced scenarios. If you have advanced networking requirements, Vultr supports multiple public IPs and up to five private networks.

A basic network configuration at Vultr consists of a single IPv4 address, configured by DHCP. To change the above setup to a static IP address configuration, replace BOOTPROTO value from dhcp to static or none as shown below. Editing /etc/sysconfig/network-scripts/ifcfg-network_interface_name.fcg ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s3īY default the configuration file will look like the block below. ~]# nmcli con show enp0s3 # here put the name of the connectionģ.
