前阵儿公司内部配置好了subverion来做版代码管理，为了便于个人修改密码，所以网上找了很多关于自助修改密码的资料，结果发现很多都是针对windows版的，即使有针对linux版的，但还是有一些问题，不能直接拿来用，说明文字也比少。
下面是我自己用的配置文件，99%来源于网络，只有很少一点点是我根据自己的实际情况修改的。希望对大家有用。
需要俩个文件：
svnpass.ini
svnpass.cgi
svnpass.ini中的内容如下：
[path]
authuserfile=/opt/svn/svnuser
logfile=/opt/svn/changepwd.log
[setup]
pwdminlen=2
[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
说明：
关键是红颜色是三行内容：
authuserfile=/opt/svn/svnuser ：subversion用户与密码文件存放位置
logfile=/opt/svn/changepwd.log ：修改密码的日志文件存放位置
pwdminlen=2 ：密码的最小长度
以上三项，根据实际情况修改即可。
其他内容保持不变即可。
svnpass.cgi文件内容如下：
#!/usr/bin/perl -w

说明：
同样需要注意三个红颜色的地方：
system("htpasswd -b $authuserfile $User $UserNewPwd"); ：注意其中的命令htpasswd，与windows下的不同
/var/www/cgi-bin/svnpass.ini"; ：配置文件的位置，就是上面的svnpass.ini位置
<a href="https://www.linuxidc.com/cgi-bin/svnpass.cgi"> ：cgi脚本的相对位置，很重要，一般就放在apache的cgi-bin目录即可
这样就可以通过url：https://192.168.1.5/cgi-bin/svnpass.cgi
这样的方式来修改密码了。当然，如果你的apache没有配置加密http的话，可以不需要https,而直接用http即可
