現(xiàn)象1、ifconfig沒有ens160配置

[test@localhost ~]$ ifconfig?

lo: flags=73<UP,LOOPBACK,RUNNING> ?mtu 65536
? ? ? ? inet 127.0.0.1 ?netmask 255.0.0.0

virbr0: flags=4099<UP,BROADCAST,MULTICAST> ?mtu 1500
? ? ? ? inet 192.168.122.1 ?netmask 255.255.255.0 ?broadcast 192.168.122.255

? ? ? ? TX packets 0 ?bytes 0 (0.0 B)

現(xiàn)象2、使用ping或者nmcli命令提示NetworkManager is not running.

[test@localhost ~]$ ping 192.168.215.1
connect: Network is unreachable
[test@localhost ~]$ nmcli
Error: NetworkManager is not running.
先啟動網(wǎng)絡(luò)管理器

 systemctl start NetworkManager?

設(shè)置自啟動

sudo systemctl enable NetworkManager

再使用nmcli查看態(tài)為unmanaged

[test@localhost ~]$ nmcli
virbr0: unmanaged
? ? ? ? "virbr0"
? ? ? ? bridge, 52:54:00:5C:DB:27, sw, mtu 1500

ens160: unmanaged
? ? ? ? "VMware VMXNET3"
? ? ? ? ethernet (vmxnet3), 00:0C:29:D1:E7:5F, hw, mtu 1500

lo: unmanaged
? ? ? ? "lo"
? ? ? ? loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536

virbr0-nic: unmanaged
? ? ? ? "virbr0-nic"
? ? ? ? tun, 52:54:00:5C:DB:27, sw, mtu 1500
?

使用nmcli connection up ens160和nmcli device up ens160?，出現(xiàn)device is strictly unmanaged報錯

?nmcli connection up ens160?
Error: Connection activation failed: No suitable device found for this connection (device lo not available because device is strictly unmanaged).

?nmcli device up ens160?
Error: Failed to add/activate new connection: Connection 'ens160' is not available on device ens160 because device is strictly unmanaged
執(zhí)行以下命令：

nmcli device set ens160 managed yes?
nmcli device status?

DEVICE ? ? ? ? ? TYPE ? ? ?STATE ? ? ?CONNECTION?
br-1c57ae1d2940 ?bridge ? ?unmanaged ?-- ? ? ? ??
br-37a032e957ba ?bridge ? ?unmanaged ?-- ? ? ? ??
br-b365648bec89 ?bridge ? ?unmanaged ?-- ? ? ? ??
docker0 ? ? ? ? ?bridge ? ?unmanaged ?-- ? ? ? ??
ens160 ? ? ? ? ? ethernet ?unmanaged ?-- ? ? ? ??

veth5707956 ? ? ?ethernet ?unmanaged ?-- ? ? ? ??
lo ? ? ? ? ? ? ? loopback ?unmanaged ?-- ? ? ? ??
解決辦法：
查看網(wǎng)絡(luò)狀態(tài)

nmcli networking?

手動開啟接管

nmcli networking on

查看連接狀態(tài)

nmcli connection show?

nmcli device status

?

或者stop服務(wù)，再修改配置文件；最后啟動服務(wù)文章來源地址http://www.zghlxwxcb.cn/news/detail-654351.html

systemctl stop NetworkManager

vi /var/lib/NetworkManager/NetworkManager.state

[main]
NetworkingEnabled=true      //修改為true
WirelessEnabled=true
WWANEnabled=true

systemctl start NetworkManager
