1.系统centos 6的系统。 先是遇到了yum失效问题， 因为6系统已经不再支持了
参考这里去搞定源问题。 http://t.zoukankan.com/f66666-p-9834835.html
2. 在安装davfs时又遇到解决Requires: libc.so.6(GLIBC_2.14)(64bit)错误解决方法
查看已安装的 gblic 版本
strings /lib64/libc.so.6 | grep GLIBC
列表明明是 glibc-2.15g还是出错。

wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
tar xf glibc-2.14.tar.gz
cd glibc-2.14
mkdir build
cd build
../configure --prefix=/opt/glibc-2.14 --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make
make install
查看系统版本命令：
lsb_release -a
LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch
Distributor ID: CentOS
Description: CentOS Linux release 7.9.2009 (Core)
Release: 7.9.2009
Codename: Core3. 运行安装命令
yum install davfs24.挂载网络盘
mkdir /mnt/16t
写法一：
mount -t davfs http://你的ip:5007/erpdata /mnt/16t
写法二：
mount.davfs http://你的ip:5007/erpdata /mnt/16t
我用的是第二中， 第一中不好使。不懂。 可能是版本问题。5. 出现busy删除不了挂载点
使用fusermount -zu /mount/xxxx6. 祝你成功
