Linux

问题 今天遇到个问题，Mac m1 上拉取之前java构建的程序发现跑不起来，第一反应arm平台不兼容之前在x86架构下构建的镜像。 现如今云厂商好多服务器都是arm架构的，加上window11都支持arm架构了（Windows on ARM），arm以后会越来越频繁使用了。 这时就得祭出docker出的利器 buildx，可以一次构建多个平台的镜像。废话不多，开搞。。 buildx其实是个容器工具 moby/buildkit:buildx-stable-1 # Create a new builder ➜ ~ docker buildx create --name mybuilder --bootstrap --use # 查看builder ➜ ~ docker buildx inspect mybuilder Name: mybuilder Driver: docker-container Nodes: Name: mybuilder0 Endpoint: unix:///var/run/docker.sock Status: running Buildkit: v0.11.2 Platforms: linux/arm64, linux/amd64, linux/amd64/v2, linux/riscv64, linux/ppc64le, linux/s390x, linux/386, linux/mips64le, linux/mips64, linux/arm/v7, linux/arm/v6 构建 # 一条命令搞定，会pudh到registry 区别于常规build ➜ ~ docker buildx build --platform linux/arm64/v8,linux/amd64 -t registry....

背景 家里路由器信号太差了想换一台，真好看到拼多多有活动（360RMB）就入手了一台，顺便手痒想刷下机，看看有什么好玩的软件和应用。 配置 红米 AX6000 搭载的是 MTK 2021 年发布的 Filogic 830 平台，具体型号是 mt7986a，四核 ARM A53 的架构， 512M 内存和 128M 闪存 刷机openwrt https://openwrt.org/toh/xiaomi/redmi_ax6000 官方固件还没有release 先不刷机了 https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/ 先贴一个官方刷机教材，等release再回头看看 https://github.com/openwrt/openwrt/pull/11115 Gain ssh access (see the link: https://openwrt.org/toh/xiaomi/redmi_ax6000#installation) Check current stock system COMMAND: cat /proc/cmdline sample OUTPUT: console=ttyS0,115200n1 loglevel=8 firmware=1 uart_en=1 if firmware=1, current system is ubi1 if firmware=0, current system is ubi0 Setup nvram If the current system is ubi1, please set it up so that the next time it will boot from ubi: nvram set boot_wait=on nvram set uart_en=1 nvram set flag_boot_rootfs=0 nvram set flag_last_success=0 nvram set flag_boot_success=1 nvram set flag_try_sys1_failed=0 nvram set flag_try_sys2_failed=0 nvram commit If the current system is ubi, please set it up so that the next time it will boot from ubi1:...
