标题: rhel7.0下面 systemctl status network 报 Failed to start LSB: Bring up/down ne

如下：

[root@rac1 ~]# systemctl status network.service
network.service - LSB: Bring up/down networking

问题原因是：

/etc/sysconfig/network-script/ifcfg-xxx 文件中没有mac地址的原因

解决办法：

1.使用ip a 获得网卡的mac地址

        [root@rac1 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> 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
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:6c:c1:8b brd ff:ff:ff:ff:ff:ff
    inet 192.168.133.120/24 brd 192.168.133.255 scope global eno16777736
    inet6 fe80::20c:29ff:fe6c:c18b/64 scope link
       valid_lft forever preferred_lft forever
3: eno33554992: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:6c:c1:95 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.218/24 brd 192.168.0.255 scope global eno33554992
    inet6 fe80::20c:29ff:fe6c:c195/64 scope link
       valid_lft forever preferred_lft forever
4: eno50332224: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:6c:c1:9f brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.120/24 brd 192.168.0.255 scope global eno50332224

2.修改 /etc/sysconfig/network-script/ifcfg-xxx 加上

HWADDR=00:0c:29:6c:c1:95

3.重新去执行 systemctl status network.service

systemctl restart network.service

network.service - LSB: Bring up/down networking
Loaded: loaded (/etc/rc.d/init.d/network)
Active: active (exited) since 三 2015-06-10 11:30:34 CST; 1s ago

Process: 11566 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=0/SUCCESS)

已经正常。
