由於在linux系統Apache+svn服務器，用戶需要自定義密碼怎么辦呢？
1.創建腳本目錄
mkdir -p /var/www/svn/svntools
2.創建apache配置文件
touch /etc/httpd/conf.d/alias.conf
3.輸入以下內容：
Alias /svntools "/var/www/svn/svntools"
<Directory "/var/www/svn/svntools">
Require valid-user
AuthType Basic
AuthName "svn tools"
AuthUserFile "/var/www/svn/passwd"
</Directory>
4.創建修改密碼的php腳本，當然不一定是php腳本,js腳本也可輕易做到等等
- <?php
- $username = $_SERVER["PHP_AUTH_USER"]; //獲取當前用戶名
- $authed_pass = $_SERVER["PHP_AUTH_PW"]; //獲取當前用戶密碼
- $input_oldpass = (isset($_REQUEST["oldpass"]) ? $_REQUEST["oldpass"] : ""); //輸入的原密碼
- $newpass = (isset($_REQUEST["newpass"]) ? $_REQUEST["newpass"] : ""); //輸入的新密碼
- $repeatpass = (isset($_REQUEST["repeatpass"]) ? $_REQUEST["repeatpass"] : ""); //輸入的重復密碼
- $action = (isset($_REQUEST["action"]) ? $_REQUEST["action"] : ""); //以hide方式提交到服務器的action
- if($action!="modify"){
- $action = "view";
- }
- else if($authed_pass!=$input_oldpass){
- $action = "oldpasswrong";
- }
- else if(empty($newpass)){
- $action = "passempty";
- }
- else if($newpass!=$repeatpass){
- $action = "passnotsame";
- }
- else{
- $action = "modify";
- }
- ?>

可能出現問題
(1).php文件放置位置 ? /var/www/svn/svntools/svnpass.php
(2).訪問路徑？http://ip:port/svntools/svnpass.php
(3).apache端口沖突？修改/etc/httpd/conf/httpd.conf中的端口號
(4).php文件亂碼問題？查看php文件格式是否為utf8
(5).修改passwd權限問題? chown root:root passwd chmod 777 * -R chmod -R passwd 777 chmod 777 passwd -R
(6). 如查看apache日志中有如下錯誤[Wed Jun 13 09:34:34.462360 2018] [core:notice] [pid 22132] AH00094: Command line: '/usr/sbin/httpd -D FOREGROUND'
sudo: unable to open audit system: Permission denied
sudo: pam_open_session: System error
sudo: policy plugin failed session initialization
sudo: unable to open audit system: Permission denied？
解決方法1：setenforce 0 ：用於關閉selinux防火牆，但重啟后失效。
[root@localhost ~]# setenforce 0
[root@localhost ~]# /usr/sbin/sestatus 1、關閉firewall防火牆，保證apache能夠訪問正常。2、沒有關閉selinux，時出現了如上錯誤。
解決方法2： 永久關閉修改selinux的配置文件，重啟后生效。
打開 selinux 配置文件
[root@localhost ~]# vim /etc/selinux/config
修改 selinux 配置文件
將SELINUX=enforcing改為SELINUX=disabled，保存后退出
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
此時獲取當前selinux防火牆的安全策略仍為Enforcing，配置文件並未生效。
[root@localhost ~]# getenforce
Enforcing
重啟
[root@localhost ~]# reboot
驗證
[root@localhost ~]# /usr/sbin/sestatus
SELinux status: disabled
[root@localhost ~]# getenforce
Disabled
(7)如果出現用戶權限不足？
首先 查看你的apache用戶或者nginx php-fpm用戶
可以使用 ps -ef | grep httpd 命令來查看 其他同理
經查我的apache用戶為apache用戶
然后 visudo 或者 vim /etc/sudoers 找到
## Allow root to run any commands anywhere
root ALL=(ALL) ALL這一行 在下邊追加
- apache ALL=(root) NOPASSWD:ALL
