建议 cp eth0 eth0:0
ifup eth0:0
修改 vim/etc/hosts
cd /home/oldboy/tools
groupadd mfs
useradd -g mfs mfs -s /sbin/nologin
yum install fuser* zlib* -y
tar zxf mfs-1.6.27-5.tar.gz
cd mfs-16.27
./configure --prefix=/application/mfs-1.6.27 --with-default-user=mfs --with-default-group=mfs
make
make install
ln -s /application/mfs-1.6.27 /application/mfs
ll /aaplication/ |grep mfs
设置用户名和组
