CentOS7.2 network.service NetworkManager.service 冲突
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
关键字：eth0, systemctl, network, gateway
