Apache htpasswd命令用法詳解
htpasswd建立和更新存儲用戶名、密碼的文本文件， 用於對HTTP用戶的basic認證。
# /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參數
-c 創建passwdfile.如果passwdfile 已經存在,那么它會重新寫入並刪去原有內容. -n 不更新passwordfile，直接顯示密碼 -m 使用MD5加密（默認） -d 使用CRYPT加密（默認） -p 使用普通文本格式的密碼 -s 使用SHA加密 -b 命令行中一並輸入用戶名和密碼而不是根據提示輸入密碼，可以看見明文，不需要交互 -D 刪除指定的用戶
實例
1. 如何利用htpasswd命令添加用戶？
# /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$zGsi7/JfQIhFXPlgqo/Wx/
生成當前目錄下生成一個linuxeye_pd文件，用戶名linuxeye_user，密碼：linuxeye_password，默認采用MD5加密方式
2. 如何在原有密碼文件中增加下一個用戶？
# /usr/local/apache/bin/htpasswd -b linuxeye_pd linuxeye.com linuxeye.com Adding password for user linuxeye.com # cat linuxeye_pd linuxeye_user:$apr1$Mugpp3FE$zGsi7/JfQIhFXPlgqo/Wx/ linuxeye.com:$apr1$/8EUOPYI$4MBxYpzotrSDcTTDZvTeT0
一定要去掉-c選項，否則覆蓋密碼文件再創建
3. 如何不更新密碼文件，只顯示加密后的用戶名和密碼？
# /usr/local/apache/bin/htpasswd -n linuxeye New password: Re-type new password: linuxeye:$apr1$bZ6Gclc4$zKRap.0BADzZIxLoxpDNv0 # /usr/local/apache/bin/htpasswd -nb linuxeye linuxeye_password linuxeye:$apr1$yvngdKGV$QrnlriJ.MxIu52Vmo.ROE1
4. 如何利用htpasswd命令刪除用戶名和密碼？
# /usr/local/apache/bin/htpasswd -D linuxeye_pd linuxeye_user Deleting password for user linuxeye_user # cat linuxeye_pd linuxeye.com:$apr1$/8EUOPYI$4MBxYpzotrSDcTTDZvTeT0
5. 如何利用htpasswd命令修改密碼？
# /usr/local/apache/bin/htpasswd -D linuxeye_pd linuxeye.com Deleting password for user linuxeye.com # /usr/local/apache/bin/htpasswd -b linuxeye_pd linuxeye.com linuxeye_passwd Adding password for user linuxeye.com # cat linuxeye_pd linuxeye.com:$apr1$74ZvB1vC$/b7ETmg8xhDPieYj0b0cE.
需要先利用htpasswd命令刪除指定用戶，再利用htpasswd添加用戶命令創建用戶即可實現修改密碼的功能。
