主机名:
如果说你没有设置主机名的话,默认是localhost.localdomain
修改配置文件的主机名
# hostnamectl set-hostname
查看网卡信息
# nmcli connection
# nmcli con show
显示具体的网络接口信息
# nmcli connection show eth0
显示所有设配状态
# nmcli device status
修改配置文件执行生效
# systemctl restart network
# nmcli connection reload
显示所有活动连接
# nmcli connection show --active
删除一个网卡连接
# nmcli connection delete eth0
添加一个网卡连接
tcpdump: listening on eth0, link-type en10mb(ethernet), capture size 65535 bytes。listening on eth0, link-type en10mb (ethernet), capture size 65535 bytes。listening on eth0, link-type en10mb (ethernet), capture size 96 bytes。
网络接口的启用与停用:
停用:
# nmcli connection down eth0
启用:
# nmcli connection up eth0
给eth0添加一个IP(IPADDR)
example device address string representation for 2 usrps with ipv4 addresses 192.168.10.2 and 192.168.20.2:。在控制台中执行ifconfig eth0 192.168.0.1 netmask 255.255.255.0linux命令linux命令,设置成192.168.0.1。auto eth0iface eth0 inet dhcp#iface eth0 inet staticaddress 192.168.0.11network 192.168.0.0netmask 255.255.255.0broadcast 192.168.0.255gateway 192.168.0.1。
给eth0添加一个子网掩码(NETMASK)
# nmcli connection modify eth0 ipv4.addresses 192.168.0.58/24
IP获取方式设置成手动(BOOTPROTO=static/none)
# nmcli connection modify eth0 ipv4.method manual
添加一个ipv4
# nmcli connection modify eth0 +ipv4.addresses 192.168.0.59/24
删除一个ipv4
[root@svr7 ~]# nmcli connection modify eth0 ipv4.method auto #将ip设为自动获取。example device address string representation for 2 usrps with ipv4 addresses 192.168.10.2 and 192.168.20.2:。interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24。
