OK1028单独使用swp0-3网口配置

1. 使用system工具创建swp0swp1swp2swp3对应的4个文件:

touch /etc/systemd/network/swp0.network

touch /etc/systemd/network/swp1.network

touch /etc/systemd/network/swp2.network

touch /etc/systemd/network/swp3.network

分别填写以下内容:

[Match]

Name=swp0

KernelCommandLine=!root=/dev/nfs

 

[Network]

#DHCP=yes

Address=192.168.0.120/24

Gateway=192.168.0.1

 

[Match]

Name=swp1

KernelCommandLine=!root=/dev/nfs

 

[Network]

#DHCP=yes

Address=192.168.1.121/24

Gateway=192.168.1.1

 

[Match]

Name=swp2

KernelCommandLine=!root=/dev/nfs

 

[Network]

#DHCP=yes

Address=192.168.2.122/24

Gateway=192.168.2.1

 

[Match]

Name=swp3

KernelCommandLine=!root=/dev/nfs

 

[Network]

#DHCP=yes

Address=192.168.3.123/24

Gateway=192.168.3.1

 

每个文件的内容和如下swp0.network内容类似,但是[Name=swp0]属性不一样,要和文件名对应。

2. 在脚本中添加重启网络服务命令(红色字体):

vim /lib/systemd/system/ifup@.service

[Unit]

Description=ifup for %I

After=local-fs.target network-pre.target apparmor.service systemd-sysctl.service

Before=network.target shutdown.target network-online.target

BindsTo=sys-subsystem-net-devices-%i.device

After=sys-subsystem-net-devices-%i.device

DefaultDependencies=no

IgnoreOnIsolate=yes

 

[Service]

# avoid stopping on shutdown via stopping system-ifup.slice

Slice=system.slice

ExecStart=/bin/sh -ec 'ifup --allow=hotplug %I; ifup --allow=auto %I; \

if ifquery %I >/dev/null; then ifquery --state %I >/dev/null;systemctl restart systemd-networkd.service;fi'

ExecStop=/sbin/ifdown %I

RemainAfterExit=true

TimeoutStartSec=5min

 

 

3. 创建swp0swp1swp2swp3对应的4个文件(此步骤是为了不连接网线ifconfig也可看到IP地址)。

 

touch /etc/network/inte**ces.d/swp0

touch /etc/network/inte**ces.d/swp1

touch /etc/network/inte**ces.d/swp2

touch /etc/network/inte**ces.d/swp3

 

分别填写以下内容:

auto swp0

iface swp0 inet static

address 192.168.0.120

netmask 255.255.255.0

gateway 192.168.0.1

broadcast 192.168.0.255

 

auto swp1

iface swp1 inet static

address 192.168.1.121

netmask 255.255.255.0

gateway 192.168.1.1

broadcast 192.168.1.255

 

auto swp2

iface swp2 inet static

address 192.168.2.122

netmask 255.255.255.0

gateway 192.168.2.1

broadcast 192.168.2.255

 

auto swp3

iface swp3 inet static

address 192.168.3.123

netmask 255.255.255.0

gateway 192.168.3.1

broadcast 192.168.3.255

 

4. 创建修改MAC地址脚本:

执行如下命令创建一个脚本文件:

root@forlinx:~#touch mac.sh

root@forlinx:~#vi mac.sh

//写入如下内容

#!/bin/sh

ifconfig swp0 hw ether c2:b6:98:52:c9:c5

ifconfig swp1 hw ether dc:b6:98:52:c9:88

ifconfig swp2 hw ether b2:b6:98:52:46:c4

ifconfig swp3 hw ether e6:02:7f:60:d1:57

修改权限:

root@forlinx:~#chmod 777 mac.sh

创建一个设置mac的服务文件

root@forlinx:~#touch /etc/systemd/system/mac.service

root@forlinx:~#vi /etc/systemd/system/mac.service

//写入如下内容

[Unit]

Description=MAC

After=basic.service X.service thermal-zone-init.service

[Service]

ExecStart=/root/mac.sh

[Install]

WantedBy=multi-user.target

其中Description一行需写入服务名,ExecStart需要写入可执行文件的绝对路径。

保存退出后,在终端上执行如下命令:

root@forlinx:~#systemctl enable /etc/systemd/system/mac.service

Created symlink /etc/systemd/system/multi-user.target.wants/mac.service/etc/systemd/system/mac.service.

此时即可将新添加的自启动服务生效,重启开发板后,此程序即可自动运行,在命令行 使用ifconfig 命令查看swp0swp1swp2swp3的网卡信息,会发现MAC地址发生了改变
