linux 普通用户切换成root免密码的实现

[root@ok ~]# vim /etc/pam.d/su

下面是/etc/pam.d/su文件的内容

#%PAM-1.0
auth      sufficient   pam_rootok.so
# Uncomment the following line to implicitly trust users in the "wheel" group.
#auth      sufficient   pam_wheel.so trust use_uid
# Uncomment the following line to require a user to be in the "wheel" group.
#auth      required    pam_wheel.so use_uid
auth      include     system-auth
account     sufficient   pam_succeed_if.so uid = 0 use_uid quiet
account     include     system-auth
password    include     system-auth
session     include     system-auth
session     optional    pam_xauth.so

将第4行的#号去掉,然后将登陆用户加入 wheel组

[root@ok ok]# usermod -G wheel ok
[ok@ok ~]$ su 
[root@ok ok]#

su直接切换成root
