CentOS7 service network start命令启动时报错解决方法

简介: CentOS7 service network start命令启动时报错解决方法

service network start命令启动时报错:


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

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!

很久没更新了,其实问题不一定是MAC的问题,也有其他的可能性。下面是另一种情况:


虚拟机里边的CentOS7重启之后无法联网了,重启network发现报错。



百度了一圈,都是叫修改mac地址的说法,但是改了之后并没有什么用,最后谷歌解决了。



解决方式:禁用NetworkManager


1. systemctl stop NetworkManager


2. systemctl disable NetworkManager


然后重启网络服务,能正常联网了!
