[root@qhfax code]# smbpasswd -a nginx
New SMB password:
Retype new SMB password:
Added user nginx.
smbpasswd 属于samba套件，能够实现添加或删除samba用户和为用户修改密码
参数：
-a：向smbpasswd文件中添加用户；
-c：指定samba的配置文件；
-x：从smbpasswd文件中删除用户；
-d：在smbpasswd文件中禁用指定的用户；
-e：在smbpasswd文件中激活指定的用户；
-n：将指定的用户的密码置空。
问题：
smbpasswd samba
New SMB password:
Retype new SMB password:
Failed to find entry for user samba.
解决方法，加参数'-a'：
# smbpasswd -a samba
New SMB password:
Retype new SMB password:
Failed to add entry for samba
解决方法：
vi /etc/samba/smb.conf 编辑smb.conf 文件
将;security = share修改为 security user
这是因为没有加相应的系统账号，所以会提示Failed to add entry for user的错误，只需增加相应的系统账号test就可以了
useradd nginx
[root@qhfax samba]# smbpasswd -a nginx
New SMB password:
Retype new SMB password:

补充：
以上设置中，smb passwd file = /etc/samba/smbpasswd文件没有生效，smbpasswd命令成功后，测试也是成功的，但是没有写入这个密码文件，最后通过查找，原来密码是存储在这里：
[root@qhfax samba]# ll /var/lib/samba/private
