```

2)编辑openEuler\_x86\_64.repo文件  
x86\_64架构

```
[root@localhost ~]# vim /etc/yum.repos.d/openEuler_x86_64.repo
[Base-OpenEuler-20.03-LTS-x86_64]
name=Base-OpenEuler-20.03-LTS-x86_64
baseurl=https://repo.openeuler.org/openEuler-20.03-LTS/OS/x86_64/
enabled=1
gpgcheck=0
```

aarch64架构

```
[root@localhost ~]# vim /etc/yum.repos.d/openEuler_x86_64.repo
[Base-OpenEuler-20.03-LTS-aarch64]
name=Base-OpenEuler-20.03-LTS-aarch64
baseurl=https://repo.openeuler.org/openEuler-20.03-LTS/OS/aarch64/
enabled=1

[root@localhost ~]# mkdir -p /var/www/html/openeuler
```

5)复制rpm包

```
[root@localhost ~]# cp -r /mnt/cdrom/Packages/ /var/www/html/openeuler/
[root@localhost ~]# cp -r /mnt/cdrom/repodata/ /var/www/html/openeuler/
```

6)编辑openEuler\_x86\_64\_local.repo文件

```
[root@localhost ~]# vim /etc/yum.repos.d/openEuler_x86_64_local.repo
[Base-OpenEuler-20.03-LTS-aarch64-local]
name=Base-OpenEuler-20.03-LTS-aarch64-local
baseurl=file:///var/www/html/openeuler

#### 5、修改主机名称

```
[root@localhost ~]# hostnamectl set-hostname openeuler100
[root@localhost ~]# hostname
openeuler100
```

#### 6、修改网络

1)修改静态IP

```
[root@openeuler100 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no

```

2)拔下ens33网卡

```
[root@openeuler100 ~]# ifdown ens33
```

3)插上ens33网卡

```
[root@openeuler100 ~]# ifup ens33
```

#### 7、配置映射

```
[root@openeuler100 ~]# vim /etc/hosts
192.168.2.100 openeuler100
```

#### 8、关闭防火墙

1)关闭防火墙

```
[root@openeuler100 ~]# systemctl stop firewalld.service
```

2)开机禁止启动防火墙

```
[root@openeuler100 ~]# systemctl disable firewalld.service
```

3)查看防火墙状态

```
[root@openeuler100 ~]# systemctl status firewalld.service
```
