linux 添加免密su

一、在user1用户下执行： su - user2 免密登录

# vim /etc/pam.d/su
#在pam_rootok.so那一行之后添加如下两行。
auth            [success=ignore default=1]      pam_succeed_if.so user = user2
auth            sufficient      pam_succeed_if.so use_uid user = user1

 

二、user1 免密su到多个用户

auth            [success=ignore default=1]      pam_succeed_if.so uid >= 1005
auth            sufficient      pam_succeed_if.so use_uid  user = user1
