问题描述：使用ifconfig命令和ip addr命令都不能够显示ip地址

回到主页

1、在开机之后，网卡没有启动起来，进行了如下操作验证

[root@df01 ~]# ifup ens33
 错误：连接激活失败：No suitable device found for this connection (device lo not available because device is strictly unmanaged).

[root@df01 ~]# systemctl start network
Job for network.service failed because the control process exited with error code.
See "systemctl status network.service" and "journalctl -xe" for details.

2、解决：先将网卡停止，然后设置为disable ，对网卡重启即可

[root@df01 ~]# systemctl stop NetworkManager    

[root@df01 ~]# systemctl disable NetworkManager  #永久关闭网络管理命令后

Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.

[root@df01 ~]# service network restart

3、输入ip addr命令后显示ip地址

[root@df01 ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:4c:9d:62 brd ff:ff:ff:ff:ff:ff
    inet 192.168.193.137/24 brd 192.168.193.255 scope global dynamic ens33

3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 52:54:00:e2:9b:de brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN group default qlen 1000
    link/ether 52:54:00:e2:9b:de brd ff:ff:ff:ff:ff:ff

4、输入ifconfig命令后显示ip地址

[root@df01 ~]# ifconfig
