初始环境
系统： centos 7 （ x86\_64 GNU/Linux） docker版本 ：Docker version 20.10.08
binfmt_misc 、QEMU依赖安装
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
验证qemu是否安装成功
[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支持的架构有 arm、mips ，qemu-mips64el的状态是 enabled
[root@VM-187-115-centos ~]# cat /proc/sys/fs/binfmt_misc/qemu-mips64el
