用户svn密码自定义

由于在linux系统Apache+svn服务器，用户需要自定义密码怎么办呢？

1.创建脚本目录

mkdir -p /var/www/svn/svntools

2.创建apache配置文件

touch /etc/httpd/conf.d/alias.conf

3.输入以下内容：

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.创建修改密码的php脚本，当然不一定是php脚本,js脚本也可轻易做到等等

<?php
$username = $_SERVER["PHP_AUTH_USER"]; //获取当前用户名
$authed_pass = $_SERVER["PHP_AUTH_PW"]; //获取当前用户密码
$input_oldpass = (isset($_REQUEST["oldpass"]) ? $_REQUEST["oldpass"] : ""); //输入的原密码
$newpass = (isset($_REQUEST["newpass"]) ? $_REQUEST["newpass"] : ""); //输入的新密码
$repeatpass = (isset($_REQUEST["repeatpass"]) ? $_REQUEST["repeatpass"] : ""); //输入的重复密码
$action = (isset($_REQUEST["action"]) ? $_REQUEST["action"] : ""); //以hide方式提交到服务器的action
if($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";
}
?>

可能出现问题

(1).php文件放置位置 ? /var/www/svn/svntools/svnpass.php

(2).访问路径？http://ip:port/svntools/svnpass.php

(3).apache端口冲突？修改/etc/httpd/conf/httpd.conf中的端口号

(4).php文件乱码问题？查看php文件格式是否为utf8

(5).修改passwd权限问题? chown root:root passwd chmod 777 * -R chmod -R passwd 777 chmod 777 passwd -R

(6).
如查看apache日志中有如下错误[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？

解决方法1：setenforce 0 ：用于关闭selinux防火墙，但重启后失效。

[root@localhost ~]# setenforce 0

[root@localhost ~]# /usr/sbin/sestatus 1、关闭firewall防火墙，保证apache能够访问正常。2、没有关闭selinux，时出现了如上错误。
解决方法2：永久关闭修改selinux的配置文件，重启后生效。
打开 selinux 配置文件
[root@localhost ~]# vim /etc/selinux/config
修改 selinux 配置文件
将SELINUX=enforcing改为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
此时获取当前selinux防火墙的安全策略仍为Enforcing，配置文件并未生效。
[root@localhost ~]# getenforce
Enforcing
重启
[root@localhost ~]# reboot
验证
[root@localhost ~]# /usr/sbin/sestatus
SELinux status:                 disabled
[root@localhost ~]# getenforce

Disabled

(7)如果出现用户权限不足？
首先查看你的apache用户或者nginx php-fpm用户
可以使用 ps -ef | grep httpd 命令来查看其他同理
经查我的apache用户为apache用户
然后 visudo 或者 vim /etc/sudoers 找到
## Allow root to run any commands anywhere
root ALL=(ALL) ALL这一行在下边追加

apache ALL=(root) NOPASSWD:ALL
