Linux下Subversion自助修改密碼

前陣兒公司內部配置好了subverion來做版代碼管理，為了便於個人修改密碼，所以網上找了很多關於自助修改密碼的資料，結果發現很多都是針對windows版的，即使有針對linux版的，但還是有一些問題，不能直接拿來用，說明文字也比少。

下面是我自己用的配置文件，99%來源於網絡，只有很少一點點是我根據自己的實際情況修改的。希望對大家有用。

需要倆個文件：
svnpass.ini
svnpass.cgi

svnpass.ini中的內容如下：

[path]
authuserfile=/opt/svn/svnuser
logfile=/opt/svn/changepwd.log
[setup]
pwdminlen=2
[html]
title=SVN用戶密碼自助修改
description=SVN用戶密碼自助修改
yourname=用戶名
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=服務器錯誤
passmustgreater=新密碼位數必須大於
twopassnotmatched=兩密碼不一致
entername=請輸入用戶名
enterpwd=密碼未輸入
errorpwd=你的密碼不正確
back=返回

說明：
關鍵是紅顏色是三行內容：
authuserfile=/opt/svn/svnuser ：subversion用戶與密碼文件存放位置
logfile=/opt/svn/changepwd.log ：修改密碼的日志文件存放位置
pwdminlen=2 ：密碼的最小長度
以上三項，根據實際情況修改即可。
其他內容保持不變即可。

svnpass.cgi文件內容如下：

#!/usr/bin/perl -w

my $time = localtime;
my $remote_id = $ENV{REMOTE_HOST} || $ENV{REMOTE_ADDR};
my $admin_email = $ENV{SERVER_ADMIN};

說明：
同樣需要注意三個紅顏色的地方：
system("htpasswd -b $authuserfile $User $UserNewPwd"); ：注意其中的命令htpasswd，與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="/cgi-bin/svnpass.cgi"> ：cgi腳本的相對位置，很重要，一般就放在apache的cgi-bin目錄即可


這樣就可以通過url：https://192.168.1.5/cgi-bin/svnpass.cgi
這樣的方式來修改密碼了。當然，如果你的apache沒有配置加密http的話，可以不需要https,而直接用http即可
