使用NAT模式的虛擬centos, 只顯示兩個(gè)網(wǎng)卡,無法連接外網(wǎng),

輸入systemctl start network后報(bào)錯(cuò)信息"

Restarting network (via systemctl): Job for network.service failed because the control process exited with error code.
See “systemctl status network.service” and “journalctl -xe” for details
禁掉系統(tǒng)自帶的NetworkManager服務(wù)就可解決

systemctl stop NetworkManager # 停止NetworkManager服務(wù)
systemctl disable NetworkManager # 設(shè)置開機(jī)不啟動(dòng)
systemctl start network # 啟動(dòng)網(wǎng)絡(luò)服務(wù)

或者

停掉NetworkManager
service NetworkManager stop
chkconfig NetworkManager off

重啟網(wǎng)絡(luò)
systemctl restart network
