给用户分配root权限(sudoers文件)??
RT
/etc/sudoers 文件里面:
“
## Next comes the main part: which users can run what software on
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
## user MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
”
上面的这句 配置,第1个"ALL"、第2个"(ALL)"、第3个"ALL",分别是什么意思? 还有什么别的取值?
