CentOS7 Failed to start LSB: Bring up/down networking.解决方法

今天用CentOS7 RDO方式安装Openstack,文档上说要disable NetworkManager, 用 network服务才行。

但是我用 service network start命令启动时报错:

[root@localhost network-scripts]# service network start

Starting network (via systemctl):  Job for network.service failed. See ‘systemctl status network.service’ and ‘journalctl -xn’ for details.[FAILED][root@localhost network-scripts]# systemctl status network.servicenetwork.service – LSB: Bring up/down networking  Loaded: loaded (/etc/rc.d/init.d/network)  Active: failed (Result: exit-code) since Sat 2015-03-07 02:53:12 EST; 6s ago  Process: 8596 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE)Mar 07 02:53:12 localhost.localdomain network[8596]: RTNETLINK answers: File …Mar 07 02:53:12 localhost.localdomain network[8596]: RTNETLINK answers: File …Mar 07 02:53:12 localhost.localdomain network[8596]: RTNETLINK answers: File …Mar 07 02:53:12 localhost.localdomain network[8596]: RTNETLINK answers: File …Mar 07 02:53:12 localhost.localdomain network[8596]: RTNETLINK answers: File …Mar 07 02:53:12 localhost.localdomain network[8596]: RTNETLINK answers: File …Mar 07 02:53:12 localhost.localdomain systemd-sysctl[8913]: Overwriting earli…Mar 07 02:53:12 localhost.localdomain systemd[1]: network.service: control pr…Mar 07 02:53:12 localhost.localdomain systemd[1]: Failed to start LSB: Bring …Mar 07 02:53:12 localhost.localdomain systemd[1]: Unit network.service entere…Hint: Some lines were ellipsized, use -l to show in full.

然后网上搜是因为没加HWADDR….这个我确实给删了….

先看log里说哪个网卡没有UP起来:

[root@localhost network-scripts]# cat /var/log/messages | grep network

ip addr查看这俩网卡的MAC:

[root@localhost network-scripts]# ip addr

1: lo: mtu 65536 qdisc noqueue state UNKNOWN     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo      valid_lft forever preferred_lft forever    inet6 ::1/128 scope host       valid_lft forever preferred_lft forever2: enp1s0f0: mtu 1500 qdisc mq master br0 state UP qlen 1000    link/ether 00:25:90:64:a9:30 brd ff:ff:ff:ff:ff:ff    inet6 fe80::225:90ff:fe64:a930/64 scope link       valid_lft forever preferred_lft forever3: enp1s0f1: mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 00:25:90:64:a9:31 brd ff:ff:ff:ff:ff:ff4: enp8s0f0: mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 00:0c:bd:05:4e:cc brd ff:ff:ff:ff:ff:ff5: enp8s0f1: mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 00:0c:bd:05:4e:cd brd ff:ff:ff:ff:ff:ff6: enp8s0f2: mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 00:0c:bd:05:4e:ce brd ff:ff:ff:ff:ff:ff7: enp8s0f3: mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 00:0c:bd:05:4e:cf brd ff:ff:ff:ff:ff:ff

然后把这俩网卡的mac写到配置文件里:

/etc/sysconfig/network-scripts/ifcfg-enp8s0f0

/etc/sysconfig/network-scripts/ifcfg-enp8s0f1

添加:

HWADDR=00:0c:bd:05:4e:cc​

然后重新启动network,就OK啦!
