编译技巧

# 自用编译的镜像, 不要使用root帐户
docker pull jcleng/buildopenwrt:20.04

#根据需要选插件
make menuconfig
#记得在Target Images适当扩大系统分区和镜像大小
#系统分区，驱动或插件多的话需要适当扩大这个分区
#(128) Kernel partition size (in MB)
#文件系统分区，基本可以理解为安装后默认的/overlay分区大小
#(512) Root filesystem partition size (in MB)


#看看有没有没下完整的包，这是查看dl目录下有没有1k以下的文件，有的话建议删除重新下，很可能没下完整
find dl -size -1024c -exec ls -l {} \;
#删除
find dl -size -1024c -exec rm -f {} \;


# 压目录
7za a -m0=lzma -mx=9 -ms=on lede.7z lede/ &
/openwrt/bin/targets
# 如果要更换架构，例如要从 x86_64 换到 MediaTek Ralink MIPS 建议执行以下命令深度清理
rm -rf ./bin ./build_dir ./tmp ./staging_dir
make clean
make dirclean
# 如果分支变更,需要删除feeds
rm -rf feeds

# 如果需要对组件重新调整，则建议先删除旧配置

rm -rf .config

make -j$(nproc) || make -j1 || make -j1 V=s

# 编译插件

make package/luci-theme-rosy/luci-theme-rosy/compile V=99

# 注：V=99 表示输出详细的 de­bug 信息

# 我这里是 x86_64 架构，编译完成插件包默认存放路径：~/openwrt/bin/packages/x86_64/base 目录下

  • dl目录的文件进行手动下载,如果下载失败,可以手动下载重新编译

  • 在docker使用rootfs文件运行openwrt

# 还是存在一些问题,luci的web无法访问/ubus,还是用libvirt来操作能ok
docker image import immortalwrt-x86-64-generic-rootfs.tar.gz immortalwrt:latest
docker run -itd --name=immortalwrt immortalwrt:latest /sbin/init
docker ps|grep immortalwrt
docker exec -it immortalwrt bash

docker restart immortalwrt

  • JCG Q30 Pro刷写openwrt

# 过渡固件/底包: 在原始管理界面进行升级刷入, 获得uboot
wget https://firmware.download.immortalwrt.eu.org/237176253/mediatek/filogic/immortalwrt-mediatek-mt7981-mt7981-spim-nand-rfb-squashfs-sysupgrade.bin

# 上一步刷完固件之后，等待大约两分钟，然后断电，按住机身背部的 Reset 按键，上电开机。等待不到 10s 左右，红灯闪烁三下然后变成蓝灯，代表已进入 U-Boot 的恢复模式 WebUI。需要设置192.168.1.2段IP, 然后访问192.168.1.1
# 固件包, Factory 映像, 记得下载之后检查sha256sum
https://firmware-selector.immortalwrt.org/?version=23.05-SNAPSHOT&target=mediatek%2Ffilogic&id=jcg_q30-ubootmod

# 进入系统后有一些其他事情可以优化。目前固件默认没完全开启 WiFi 硬件转发加速，天灵修改这个配置之前，可能需要手动开启。SSH 或 TTYD 连接到路由器并执行：
opkg update && opkg install bridger
echo 'mt7915e wed_enable=Y' > /etc/modules.d/mt7915e
