Linux下SVN遠程web密碼修改

 Linux遠程修改使用者密碼工具

使用方法:
1、將檔案ChangePasswd.cgi和ChangePasswd.ini 放到apche安裝目錄下的cgi-bin下
2、確認ChangePasswd.cgi 程式第1行 ，prel工具的位置   （我的：#!/usr/bin/perl -w）
/usr/bin/perl
3、修改ChangePasswd.cgi 第84行 改成htpasswd所在的路徑 （我的：/project/apache/bin/htpasswd）
4、修改ChangePasswd.cgi 128行 ini檔案改成完整路徑 （我的：/project/apache/cgi-bin/ChangePasswd.ini）
5、設定檔 ChangePasswd.ini 第2行authuserfile= 密碼存放路徑 （我的：/svndata/svn-auth-file/passwd）
6、設定檔 ChangePasswd.ini 第3行logfile= 動作記錄存放路徑 （我的：/project/apache/cgi-bin/ChangPasswd.log）

注意細節：
1、用htpasswd時 切勿用-m參數 如果以前用的話，可重新輸入一次進行更新
2、ChangPasswd.log 必須有“w”寫入許可權

 

把以下內容複寫下來儲存為ini尾碼的檔案ChangePasswd.ini

[path]
authuserfile=/repository/auth/authfile
logfile=/repository/auth/ChangPasswd.log
[setup]
pwdminlen=6
[html]
title=SVN使用者密碼自助修改
description=SVN使用者密碼自助修改
yourname=使用者名稱
oldpwd=舊密碼
newpwd1=新密碼
newpwd2=確認新密碼
btn_change=修 改
btn_reset=重 置

changepwdok=成功修改密碼
changepwdfailed=修改密碼失敗
servererror=伺服器錯誤
passmustgreater=新密碼位元必須大於
twopassnotmatched=兩密碼不一致
entername=請輸入使用者名稱
enterpwd=密碼未輸入
errorpwd=你的密碼不正確
back=返回

按以上的1-6步驟修改完成後即可通過遠程web修改使用者的密碼了
