今天通过NetworkManager Gui修改了网卡eth0的Gateway,后来reboot了虚拟机,然后奇怪的事情出现了.
1.ifconfig
not found eth0
2.systemctl status network
, 发现如下错误
Bringing up interface eth0: Error: Connection activation failed: No suitable device found for this connection.
3.ifup eth0
报一样的错误
google 发现 NetworkManager, network竟然可能会发生冲突. 为避免冲突可以在 /etc/sysconfig/network-scripts/ifcfg-eth* 文件 Disabling Network Manager
TYPE=Ethernet
BOOTPROTO=none
DEVICE=eth0
ONBOOT=yes
#DNS2=114.114.114.114
#DNS1=127.0.0.1
IPADDR=10.0.0.57
PREFIX=24
GATEWAY=10.0.0.1
NM_CONTROLLED=no # add this line
systemctl start network
ok
或者:
systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl start network
