初始環(huán)境

系統(tǒng)： centos 7 （ x86\_64 GNU/Linux） docker版本 ：Docker version 20.10.08

binfmt_misc 、QEMU依賴安裝

docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

驗證qemu是否安裝成功

[root@VM-187-115-centos ~]# ls  /proc/sys/fs/binfmt_misc/ 
kshcomp          qemu-arm      qemu-m68k          qemu-mips64    qemu-mipsn32el  qemu-ppc64le  qemu-sh4          qemu-sparc64   status
qemu-aarch64     qemu-armeb    qemu-microblaze    qemu-mips64el  qemu-or1k       qemu-riscv32  qemu-sh4eb        qemu-xtensa
qemu-aarch64_be  qemu-hexagon  qemu-microblazeel  qemu-mipsel    qemu-ppc        qemu-riscv64  qemu-sparc        qemu-xtensaeb
qemu-alpha       qemu-hppa     qemu-mips          qemu-mipsn32   qemu-ppc64      qemu-s390x    qemu-sparc32plus  register

可以看到qemu支持的架構(gòu)有 arm、mips ，qemu-mips64el的狀態(tài)是 enabled

[root@VM-187-115-centos ~]# cat /proc/sys/fs/binfmt_misc/qemu-mips64el
