htpasswd建立和更新存储用户名、密码的文本文件, 用于对HTTP用户的basic认证。
# /usr/local/apache/bin/htpasswd --help Usage: htpasswd [-cmdpsD] passwordfile username htpasswd -b[cmdpsD] passwordfile username password htpasswd -n[mdps] username htpasswd -nb[mdps] username password -c Create a new file. -n Don't update file; display results on stdout. -m Force MD5 encryption of the password (default). -d Force CRYPT encryption of the password. -p Do not encrypt the password (plaintext). -s Force SHA encryption of the password. -b Use the password from the command line rather than prompting for it. -D Delete the specified user. On other systems than Windows, NetWare and TPF the '-p' flag will probably not work. The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.
htpasswd参数
-c 创建passwdfile.如果passwdfile 已经存在,那么它会重新写入并删去原有内容. -n 不更新passwordfile,直接显示密码 -m 使用MD5加密(默认) -d 使用CRYPT加密(默认) -p 使用普通文本格式的密码 -s 使用SHA加密 -b 命令行中一并输入用户名和密码而不是根据提示输入密码,可以看见明文,不需要交互 -D 删除指定的用户
实例
1. 如何利用htpasswd命令添加用户?
# /usr/local/apache/bin/htpasswd -bc linuxeye_pd linuxeye_user linuxeye_password Adding password for user linuxeye_user # cat linuxeye_pd linuxeye_user:$apr1$Mugpp3FE$zGsi7/JfQIhFXPlgqo/Wx/
生成当前目录下生成一个linuxeye_pd文件,用户名linuxeye_user,密码:linuxeye_password,默认采用MD5加密方式
2. 如何在原有密码文件中增加下一个用户?
# /usr/local/apache/bin/htpasswd -b linuxeye_pd trustauth.cn trustauth.cn Adding password for user trustauth.cn # cat linuxeye_pd linuxeye_user:$apr1$Mugpp3FE$zGsi7/JfQIhFXPlgqo/Wx/ trustauth.cn:$apr1$/8EUOPYI$4MBxYpzotrSDcTTDZvTeT0
一定要去掉-c选项,否则覆盖密码文件再创建
3. 如何不更新密码文件,只显示加密后的用户名和密码?
# /usr/local/apache/bin/htpasswd -n linuxeye New password: Re-type new password: linuxeye:$apr1$bZ6Gclc4$zKRap.0BADzZIxLoxpDNv0 # /usr/local/apache/bin/htpasswd -nb linuxeye linuxeye_password linuxeye:$apr1$yvngdKGV$QrnlriJ.MxIu52Vmo.ROE1
4. 如何利用htpasswd命令删除用户名和密码?
# /usr/local/apache/bin/htpasswd -D linuxeye_pd linuxeye_user Deleting password for user linuxeye_user # cat linuxeye_pd trustauth.cn:$apr1$/8EUOPYI$4MBxYpzotrSDcTTDZvTeT0
5. 如何利用htpasswd命令修改密码?
# /usr/local/apache/bin/htpasswd -D linuxeye_pd trustauth.cn Deleting password for user trustauth.cn # /usr/local/apache/bin/htpasswd -b linuxeye_pd trustauth.cn linuxeye_passwd Adding password for user trustauth.cn # cat linuxeye_pd trustauth.cn:$apr1$74ZvB1vC$/b7ETmg8xhDPieYj0b0cE.
需要先利用htpasswd命令删除指定用户,再利用htpasswd添加用户命令创建用户即可实现修改密码的功能。
