Sudo:無法設置使用者以避免被要求輸入密碼
我跑:
sudo visudo
並為我的使用者設置此行
myuser ALL=(ALL) NOPASSWD: ALL
但是,當我執行
sudo
命令時,我仍然被要求輸入密碼如何設置使用者以便不詢問密碼?
這是完整的 /etc/sudoers 文件:
## Sudoers allows particular users to run various commands as ## the root user, without needing the root password. ## ## Examples are provided at the bottom of the file for collections ## of related commands, which can then be delegated out to particular ## users or groups. ## ## This file must be edited with the 'visudo' command. ## Host Aliases ## Groups of machines. You may prefer to use hostnames (perhaps using ## wildcards for entire domains) or IP addresses instead. # Host_Alias FILESERVERS = fs1, fs2 # Host_Alias MAILSERVERS = smtp, smtp2 ## User Aliases ## These aren't often necessary, as you can use regular groups ## (ie, from files, LDAP, NIS, etc) in this file - just use %groupname ## rather than USERALIAS # User_Alias ADMINS = jsmith, mikem ## Command Aliases ## These are groups of related commands... ## Networking # Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig, /bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/mii-tool ## Installation and management of software # Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum ## Services # Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig ## Updating the locate database # Cmnd_Alias LOCATE = /usr/bin/updatedb ## Storage # Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/parted, /sbin/partprobe, /bin/mount, /bin/umount ## Delegating permissions # Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown, /bin/chmod, /bin/chgrp ## Processes # Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall ## Drivers # Cmnd_Alias DRIVERS = /sbin/modprobe # Defaults specification # # Refuse to run if unable to disable echo on the tty. # Defaults !visiblepw # # Preserving HOME has security implications since many programs # use it when searching for configuration files.

可能在你的線路之後有類似的東西:
%sudo ALL=(ALL:ALL) ALL
或類似的(即
%admin
,%wheel
等)。因為:
當一個使用者有多個條目匹配時,它們將按順序應用。如果有多個匹配項,則使用最後一個匹配項(不一定是最具體的匹配項)。
你應該把
myuser ALL=(ALL) NOPASSWD: ALL
在任何組指令之後。
既然你有:
#includedir /etc/sudoers.d
它必須是
/etc/sudoers.d
.刪除線條
myuser ALL=(ALL) NOPASSWD: ALL %mygroup ALL=(ALL:ALL) ALL
把你的線
myuser ALL=(ALL) NOPASSWD: ALL
之後
#includedir
並檢查它是否以這種方式工作。
