centos 7和suse11、suse12,密码复杂度设置
centos7:(添加红框处配置，位置也要固定)
cat /etc/pam.d/system-auth
password requisite pam_cracklib.so ucredit=-1 lcredit=-1 dcredit=-1
password requisite pam_pwquality.so try_first_pass local_users_only retry=3 authtok_type=
password sufficient pam_unix.so sha512 shadow nullok try_first_pass use_authtok
password required pam_deny.so
cat /etc/login.defs （口令最小长度设置）
添加：PASS_MIN_LEN 8
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
suse11:(添加红框处配置，位置也要固定)
cat /etc/pam.d/common-password
password requisite pam_pwcheck.so nullok cracklib
password requisite pam_cracklib.so minlen=8 ucredit=-1 lcredit=-1 dcredit=-1 ocredit=-1
password required pam_unix2.so use_authtok nullok
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
suse12:(添加红框处配置，位置也要固定)
cat /etc/pam.d/common-password
password requisite pam_cracklib.so minlen=8 ucredit=-1 lcredit=-1 dcredit=-1 ocredit=-1
password optional pam_gnome_keyring.so use_authtok
password required pam_unix.so use_authtok nullok shadow try_first_pass
