1：启动网卡报错（Failed to start LSB: Bring up/down networking ）解决办法总结
将 NetworkManager关闭，
systemctl stop NetworkManager
systemctl disable NetworkManager
然后重启：
systemctl start NetworkManager
systemctl enable NetworkManager
service network restart 或 systemctl restart network
仍然失败，但是原先那个错误已经不见了
reboot 重启，再试试 ifconfig
好了?
再次重启 service network restart
服务已启动，杀掉进程，重启成功
ifconfig查看ip,本地ping通了
