EVE-NG下安装OpenWRT x86
新建目录，在EVE-NG中以“linux-”开头，添加节点的时候就可以找到这个镜像
root@eve-ng:~# mkdir /opt/unetlab/addons/qemu/linux-openwrt 创建虚拟机的硬盘镜像文件 root@eve-ng:~# qemu-img create -f qcow2 hda.qcow2 1G Formatting 'hda.qcow2', fmt=qcow2 size=1073741824 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16 root@eve-ng:~# ll -rw-r--r-- 1 root root 42281968 Aug 12 02:23 hda.qcow2 -rw-r--r-- 1 root root 42281968 Aug 12 02:19 openwrt-koolshare-mod-v2.19-r8118-26796a2-x86-64-combined-squashfs.img.gz
解压openwrt镜像（之前已经将openwrt的镜像通过SFTP上传到EVE-NG主机中）
root@eve-ng:~# gzip -d openwrt-koolshare-mod-v2.19-r8118-26796a2-x86-64-combined-squashfs.img.gz root@eve-ng:~# ll -rw-r--r-- 1 root root 42281968 Aug 12 02:23 hda.qcow2 -rw-r--r-- 1 root root 248844387 Aug 12 02:19 openwrt-koolshare-mod-v2.19-r8118-26796a2-x86-64-combined-squashfs.img
使用Linux命令dd，将openwrt镜像写入刚才创建的空白硬盘镜像文件。这步操作相当于克隆。
root@eve-ng:~# dd if=openwrt-koolshare-mod-v2.19-r8118-26796a2-x86-64-combined-squashfs.img of=hda.qcow2

486024+1 records out
248844387 bytes (249 MB, 237 MiB) copied, 1.41203 s, 176 MB/s
将克隆好的硬盘镜像文件移动到刚才创建的目录
root@eve-ng:~# mv hda.qcow2 /opt/unetlab/addons/qemu/linux-openwrt/
在EVE-NG页面中新建一个Lab，添加一个节点，选择“linux-openwrt” 启动虚拟机时，出现如下提示
skipd[4325]: can't create table 14: unable to open database file
虚拟机中没有network这个文件，创建文件时提示没有空间

重新克隆

克隆后再使用qemu-img命令增大硬盘镜像文件的大小
root@eve-ng:~# qemu-img resize hda.qcow2 +750M WARNING: Image format was not specified for 'hda.qcow2' and probing guessed raw. Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted. Specify the 'raw' format explicitly to remove the restrictions.

启动openwrt后可以修改配置了 由于openwrt默认已经做了一些配置，如Lan口的IP为192.168.1.1/24，但这些配置跟我现有的网络不同网段，需要修改openwrt的IP
root@Openwrt:/# vim /etc/config/network config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fddc:9d6e:885b::/48' config interface 'lan' option type 'bridge' option ifname 'eth0 eth1 eth2 eth3' option proto 'static' option ipaddr '192.168.1.1' option netmask '255.255.255.0' option ip6assign '60' 默认LAN口IP为192.168.1.1/24 虚拟机中的网卡eth0与默认配置中的eth0刚好是一样的 config interface 'wan' option ifname 'eth4' option proto 'dhcp' config interface 'wan6' option ifname 'eth4' option proto 'dhcpv6' 修改为 config interface 'lan' option type 'bridge' option ifname 'eth0 eth1 eth2 eth3' option proto 'static' option ipaddr '10.55.55.25' option netmask '255.255.255.224' option ip6assign '60' option gateway '10.55.55.1' option broadcast '255.255.255.255' option dns '114.114.114.114 8.8.8.8' 在命令行下修改IP，使得可以从Web页面登录，之后可以在页面修改IP等信息 root@Openwrt:/# service network restart
测试openwrt能否连接互联网
