二、主要操作：
    1. # apt-get install binfmt-support qemu qemu-user-static debootstrap
    2. # mkdir debian_armhf_wheezy
    3. # debootstrap --foreign --arch armhf wheezy debian_armhf_wheezy http://ftp.debian.org/debian/
    4. # cp /usr/bin/qemu-arm-static debian_armhf_wheezy/usr/bin
    5. # DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true LC_ALL=C LANGUAGE=C LANG=C chroot debian_armhf_wheezy /debootstrap/debootstrap --second-stage
    6. # DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true LC_ALL=C LANGUAGE=C LANG=C chroot debian_armhf_wheezy dpkg --configure -a
    7. # sudo chroot debian_armhf_wheezy
    8. # vi /etc/apt/source.list
        deb http://cdn.debian.net/debian wheezy main contrib non-free
        deb-src http://cdn.debian.net/debian wheezy main contrib non-free

三、运行MySQL出错：
    1. 查看信息：
        root@aplex:/var/log/mysql# mysql_install_db --user=mysql --ldata=/var/lib/mysql/
        WARNING: The host 'aplex' could not be looked up with resolveip.
        This probably means that your libc libraries are not 100 % compatible
        with this binary MySQL version. The MySQL daemon, mysqld, should work
        normally with the exception that host name resolving will not work.
        This means that you should use IP addresses instead of hostnames
        when specifying MySQL privileges !
        Installing MySQL system tables...

        000102  9:38:54 [Warning] Ignoring user change to 'mysql' because the user was set to 'root' earlier on the command line

        000102  9:38:54 [Note] /usr/sbin/mysqld (mysqld 5.5.54-0+deb7u2) starting as process 4915 ...
        ERROR: 130  Incorrect file format 'db'
        000102  9:38:54 [ERROR] Aborting

        000102  9:38:54 [Note] /usr/sbin/mysqld: Shutdown complete

        Installation of system tables failed!  Examine the logs in
        /var/lib/mysql/ for more information.

        You can try to start the mysqld daemon with:

            shell> /usr/sbin/mysqld --skip-grant &

        and use the command line tool /usr/bin/mysql
        to connect to the mysql database and look at the grant tables:

            shell> /usr/bin/mysql -u root mysql
            mysql> show tables

        Try 'mysqld --help' if you have problems with paths.  Using --log
        gives you a log in /var/lib/mysql/ that may be helpful.

        Please consult the MySQL manual section
        'Problems running mysql_install_db', and the manual section that
        describes problems on your OS.  Another information source are the
        MySQL email archives available at http://lists.mysql.com/.

        Please check all of the above before submitting a bug report
        at http://bugs.mysql.com/

        root@aplex:/var/log/mysql#
    2. 避开权限进入：
        /usr/sbin/mysqld --skip-grant &
