Fedora 28 server 配置网络

1. Set static IP address to the server. ( Replace the section [ens3] to your own interface name )

# set hostname
[root@localhost ~]# hostnamectl set-hostname dlp.srv.world
# display devices
[root@localhost ~]# nmcli device 
DEVICE  TYPE      STATE      CONNECTION
ens3    ethernet  connected  ens3
lo      loopback  unmanaged  --

# set IPv4 address
[root@localhost ~]# nmcli connection mod ens3 ipv4.addresses 10.0.0.30/24 
# set default gateway
[root@localhost ~]# nmcli connection mod ens3 ipv4.gateway 10.0.0.1 
# set DNS
[root@localhost ~]# nmcli connection mod ens3 ipv4.dns 10.0.0.1 
# set manual for static setting (it's [auto] for DHCP)
[root@localhost ~]# nmcli connection mod ens3 ipv4.method manual 
# restart the interface and reload the settings
[root@localhost ~]# nmcli connection down ens3; nmcli connection up ens3 
Connection 'ens3' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1)
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2)
# show settings
[root@localhost ~]# nmcli device show ens3

2. Disable IPv6 like follows if you do not need it.

[root@localhost ~]# vi /etc/default/grub
# line 7: add
GRUB_CMDLINE_LINUX="ipv6.disable=1 resume=/dev/mapper/fedora-swap.....
# apply changes
[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg 
[root@localhost ~]# reboot
