1、查看连接情况
[root@node1 ~]# nmcli connection show NAME UUID TYPE DEVICE ens33 3d2b9aad-a175-46ee-abee-ada67cd7a6c3 ethernet ens33 virbr0 ce5b08c2-eb1a-4d60-8b8d-716935662f71 bridge virbr0
2、配置ip地址
[root@node1 ~]# nmcli connection modify ens33 ipv4.addresses 192.168.8.120/24 ipv4.gateway 192.168.8.1 connection.autoconnect yes ipv4.method manual
3、启动网络服务
[root@node1 ~]# nmcli connection up ens33 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4) [root@node1 ~]#
4、查看连接状态
[root@node1 ~]# nmcli connection show ens33 connection.id: ens33 connection.uuid: 3d2b9aad-a175-46ee-abee-ada67cd7a6c3 connection.stable-id: -- connection.type: 802-3-ethernet connection.interface-name: ens33 connection.autoconnect: yes connection.autoconnect-priority: 0 connection.autoconnect-retries: -1 (default) connection.auth-retries: -1 connection.timestamp: 1569549304 connection.read-only: no connection.permissions: -- connection.zone: -- connection.master: -- connection.slave-type: -- connection.autoconnect-slaves: -1 (default) connection.secondaries: -- connection.gateway-ping-timeout: 0 connection.metered: unknown connection.lldp: default connection.mdns: -1 (default) 802-3-ethernet.port: -- 802-3-ethernet.speed: 0 802-3-ethernet.duplex: -- 802-3-ethernet.auto-negotiate: no 802-3-ethernet.mac-address: -- 802-3-ethernet.cloned-mac-address: -- 802-3-ethernet.generate-mac-address-mask:-- 802-3-ethernet.mac-address-blacklist: -- 802-3-ethernet.mtu: auto 802-3-ethernet.s390-subchannels: -- 802-3-ethernet.s390-nettype: -- 802-3-ethernet.s390-options: -- 802-3-ethernet.wake-on-lan: default 802-3-ethernet.wake-on-lan-password: -- ipv4.method: manual ipv4.dns: -- ipv4.dns-search: -- ipv4.dns-options: "" ipv4.dns-priority: 0 ipv4.addresses: 192.168.8.120/24 ipv4.gateway: 192.168.8.1 ipv4.routes: -- ipv4.route-metric: -1 ipv4.route-table: 0 (unspec) ipv4.ignore-auto-routes: no ipv4.ignore-auto-dns: no ipv4.dhcp-client-id: -- ipv4.dhcp-timeout: 0 (default) ipv4.dhcp-send-hostname: yes ipv4.dhcp-hostname: -- ipv4.dhcp-fqdn: -- ipv4.never-default: no ipv4.may-fail: yes ipv4.dad-timeout: -1 (default) ipv6.method: auto ipv6.dns: -- ipv6.dns-search: -- ipv6.dns-options: "" ipv6.dns-priority: 0 ipv6.addresses: -- ipv6.gateway: -- ipv6.routes: -- ipv6.route-metric: -1 ipv6.route-table: 0 (unspec) ipv6.ignore-auto-routes: no ipv6.ignore-auto-dns: no ipv6.never-default: no ipv6.may-fail: yes ipv6.ip6-privacy: 2 (enabled, prefer temporary IP) ipv6.addr-gen-mode: stable-privacy ipv6.dhcp-duid: -- ipv6.dhcp-send-hostname: yes ipv6.dhcp-hostname: -- ipv6.token: -- proxy.method: none proxy.browser-only: no proxy.pac-url: -- proxy.pac-script: -- GENERAL.NAME: ens33 GENERAL.UUID: 3d2b9aad-a175-46ee-abee-ada67cd7a6c3 GENERAL.DEVICES: ens33 GENERAL.STATE: activated GENERAL.DEFAULT: yes GENERAL.DEFAULT6: no GENERAL.SPEC-OBJECT: -- GENERAL.VPN: no GENERAL.DBUS-PATH: /org/freedesktop/NetworkManager/ActiveConnection/4 GENERAL.CON-PATH: /org/freedesktop/NetworkManager/Settings/1 GENERAL.ZONE: -- GENERAL.MASTER-PATH: -- IP4.ADDRESS[1]: 192.168.8.120/24 IP4.GATEWAY: 192.168.8.1 IP4.ROUTE[1]: dst = 192.168.8.0/24, nh = 0.0.0.0, mt = 100 IP4.ROUTE[2]: dst = 0.0.0.0/0, nh = 192.168.8.1, mt = 100 IP6.ADDRESS[1]: fe80::79a:9154:ad71:1b7e/64 IP6.GATEWAY: -- IP6.ROUTE[1]: dst = fe80::/64, nh = ::, mt = 100 IP6.ROUTE[2]: dst = ff00::/8, nh = ::, mt = 256, table=255
5、如何修改ip地址
nmcli connection modify ens33 ipv4.addresses 192.168.8.170/24
