su - root:表示人以root身份登录
just like login as root, then the shell is login shell,
which mean it will expericene a login process,
usually .bash_profile and .bashrc will be sourced
su root:表示与root建立一个链接，通过root执行命令
like you open an interactive shell in root name,
then only .bashrc will be sourced. (责任编辑：IT)
