注意：

1、ChangePasswd.ini、ChangePasswd.cgi必须放在apache的cgi-bin(根据自己电脑上的路径来，我的是/var/www/cgi-bin)下。

2、修改密码文件的所有者是apache,如果不是，执行chown apache:apache passwd(密码文件)。

3、如果密码是用htpasswd -c 或-m所建，执行htpasswd -b /etc/httpd/passwd usrname password更新。

一、创建ChangePasswd.ini文件

创建一个空文件：

a.将其命名为ChangePasswd.ini并将以下内容复制到此文件中。

b.注意将以下红色部分改为你自己的路径。第一行为所建用户和密码文件的路径。第二行为修改密码的日志的路径（该文件是自己建的）。

[path]

authuserfile=/etc/httpd/passwd

logfile=/var/www/cgi-bin/ChangePasswd.log

[setup]

pwdminlen=6

[html]

title=SVN用户密码自助修改

description=SVN用户密码自助修改

yourname=用户名

oldpwd=旧密码

newpwd1=新密码

newpwd2=确认新密码

btn_change=修改

btn_reset=重置

changepwdok=成功修改密码

changepwdfailed=修改密码失败

servererror=服务器错误

passmustgreater=新密码位数必须大于

twopassnotmatched=两密码不一致

entername=请输入用户名

enterpwd=密码未输入

errorpwd=你的密码不正确

back=返回

二、创建ChangePasswd.cgi文件并设置其权限

创建一个空文件，将以下内容复制到创建的文件里并更名为ChangePasswd.cgi，设置其权限为755（可执行）

命令：chmod 755 ChangePasswd.cgi.

#!/usr/bin/perl -w

use strict;

my $time = localtime;

my $remote_id = $ENV{REMOTE_HOST} || $ENV{REMOTE_ADDR};

my $pwd_not_allchar = "密码不能全为字符";

sub Writer_Log{

my $loginfo ="[".$time."] "." [".$remote_id."] "." || ".$_[0];

open LOGFILE,">>$logfile" or die "Couldn't open LOG FILE for writing: $!";

print LOGFILE ("$loginfo\n");

close LOGFILE;

}

三、创建ChangePasswd.log文件并设置其权限。

进入目标位置（即你想创建ChangePasswd.log的位置），如： /var/www/cgi-bin(根据自己的位置定)，创建一个名为ChangePasswd.log的文件并赋予该文件写的权限：

命令：chmod 666 ChangePasswd.log

四、修改密码

通过http://ip:80/cgi-bin/ChangePasswd.cgi修改密码。

80对应自己设置的端口。

PS：只针对svn：//地址，这样的svn用户修改，如果是http的用户是识别不了的，会提示你的密码不正确。
