一、网络配置

1、配置IP，vi /etc/sysconfig/network/ifcfg-eth0

BOOTPROTO=static

IPADDR=192.168.100.100

NETMASK=255.255.255.0

NETWORK='192.168.100.0'

2、配置路由，vi /etc/sysconfig/network/routes

default 192.168.100.2

3、配置DNS，vi /etc/resolv.conf

nameserver 223.5.5.5

nameserver 223.6.6.6

4、修改主机名，vi /etc/hostsname，vi /etc/hosts

5、重启网卡，service network restart

二、切换软件安装源

zypper mr -da

zypper addrepo -f http://mirrors.aliyun.com/opensuse/distribution/leap/15.1/repo/oss/ Aliyun-openSUSE-15.1-Oss

zypper addrepo -f http://mirrors.aliyun.com/opensuse/distribution/leap/15.1/repo/non-oss/ Aliyun-openSUSE-15.1-Non-Oss

zypper addrepo -f http://mirrors.aliyun.com/opensuse/update/leap/15.1/oss/ Aliyun-openSUSE-15.1-Update-Oss

zypper addrepo -f http://mirrors.aliyun.com/opensuse/update/leap/15.1/non-oss/ Aliyun-openSUSE-15.1-Update-Non-Oss

zypper update

三、允许root用户远程ssh

1、配置SSHD服务，vi /etc/ssh/sshd_config

将#PasswordAuthentication no的注释去掉，并将no改为yes

将#PermitRootLogin yes的注释去掉

重新启动SSH服务service sshd restart

2、配置防火墙，vi /etc/sysconfig/SuSEfirewall2.d/services/sshd

添加：TCP="22"或者TCP="ssh"

四、设置用户自动登录

Yast2 → Security and User → User and Group Management → Expert Options → Login Settings

vi /etc/sysconfig/displaymanager

DISPLAYMANAGER_AUTOLOGIN="root"
