linux设置sudo不要密码

Posted 2022-02-13 xiaoliu66007

linux下，普通用户，sudo时需要密码

改成没密码，

vi /etc/sudoers

在 root ALL=(ALL) ALL后加一行

sysusr ALL=(ALL) NOPASSWD: ALL　　（92行）
并且在sysusr账号所在组：%wheel，加上组sudo不加密码的设置（102行），保存即可生效。

     81 ## Next comes the main part: which users can run what software on
     82 ## which machines (the sudoers file can be shared between multiple
     83 ## systems).
     84 ## Syntax:
     85 ##
     86 ##      user    MACHINE=COMMANDS
     87 ##
     88 ## The COMMANDS section may have other options added to it.
     89 ##
     90 ## Allow root to run any commands anywhere
     91 root ALL=(ALL) ALL
     92 sysusr ALL=(ALL) NOPASSWD: ALL
     93 
     94 ## Allows members of the ‘sys‘ group to run networking, software,
     95 ## service management apps and more.
     96 # %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS
     97 
     98 ## Allows people in group wheel to run all commands
     99 %wheel ALL=(ALL) ALL
    100 
    101 ## Same thing without a password
    102 # %wheel        ALL=(ALL)       NOPASSWD: ALL //这一行的#要放开
    103 
    104 ## Allows members of the users group to mount and unmount the
    105 ## cdrom as root
    106 # %users  ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom
    107 
    108 ## Allows members of the users group to shutdown this system
    109 # %users  localhost=/sbin/shutdown -h now
    110 
    111 ## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment)
    112 #includedir /etc/sudoers.d
