问题:网络重启失败
如下:
[root@localhost ~]# systemctl restart network
Job for network.service failed because the control process exited with error code.
See “systemctl status network.service” and “journalctl -xe” for details.
根据提示,执行:
[root@localhost ~]# systemctl status network
● network.service – LSB: Bring up/down networking
Loaded: loaded (/etc/rc.d/init.d/network; generated)
Active: failed (Result: exit-code) since Tue 2020-01-14 10:49:23 CST; 43min ago

思路整理:
网络服务异常可能原因:
1.网络配置出错;
2. /etc/sysconfig/network-scripts路径下统一网卡,出现多个配置文件,干扰网络
3. NM服务影响(network服务启动会优先通过NM管理,其次走ip a)
排查下来,本次发现我的 /etc/sysconfig/network-scripts路径下一个网卡有多个配置文件,删除后,重新建立配置文件
重新建立:
1). 可以命令配置文件:(以下是我的网卡)
[root@localhost network-scripts]# cat ifcfg-eth0
HWADDR=00:0E:C6:54:0A:BF
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
IPADDR=10.2.30.91
PREFIX=16
GATEWAY=10.2.0.2
DNS1=223.5.5.5
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth0
UUID=3c0b2360-d585-4209-8aba-66ac59ff4645
ONBOOT=yes
2). 图形配置:
先删除图形存在的网络配置信息,重新建立(类似win,不多说)
3. 最后,重启网络,成功。
[root@localhost ~]# systemctl restart network
[root@localhost ~]#
