[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
以上就是小编为大家带来的linux 普通用户切换成root免密码的实现全部内容了，希望大家多多支持考高分网~
