openEuler couldnt resolve host name

openeuler 安装后无法上网

执行yum update命令报错could not resolve host name

很多文章说是DNS域名解析问题，在/etc/resolv.conf文件末尾添加nameserver 114.114.114.114和nameserver 8.8.8.8，但是没有奏效。

通过ifconfig命令查看网卡设备为enp0s3

# sudo vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

# sudo vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

将

ONBOOT=no

更改为

ONBOOT=yes

重启即可
