linux弹出界面eth0/eth1错误 激活连接失败 master connection not found or invalid

原因是NetworkManager 开启导致。关闭NetworkManager服务，否则会报错master connection not found or invalid。主要是因为NetworkManager接管了网卡启动，将NetworkManager停掉，并启动 network 服务来接管网卡服务，请查看如下四条命令：

1 service NetworkManager stop
2 chkconfig NetworkManager off
3 chkconfig network on
4 service network start
