在php使用redis作为session的保存工具时,遇到session被清理的问题导致用户没法登陆
请问该如何解决
我使用两种方式来定义session的保存机制
一种是
<code>php</code><code>ini_set('session.save_handler','Redis'); ini_set('session.save_path','tcp://localhost:6379'); </code>
另一种是
<code>session.save_handler = Redis session.save_path = "tcp://localhost:6379" </code>
在php5.3.28和5.5.10下均不能正常使用session
但是都不能用,请问各位大侠如何解决
ps
@woshicixide 说我写的不详细 那么我就将所有的步骤写一遍
首先是开启redis 使用脚本
redis-server.exe redis.conf
命令运行redis服务器
然后在php.ini中修改session.save_handler 为redissession.save_handler = Redis
然后在php.ini中修改session.save_path 为 "tcp://localhost:6379"session.save_path = "tcp://localhost:6379"
然后重启Apache服务,重载php.ini
打开登陆页面http://localhost/login.php 输入用户名密码 登陆
浏览器自动跳转到登录成功页面,然后自动返回到登陆页ps 在loginaction.php中将登陆的userid写入到session中来判断是否登陆

我感觉是你的配置有问题吧,我贴一下我的配置。
[Session]
; Handler used to store/retrieve data.
; http://php.net/session.save-handler
session.save_handler = redis
session.save_path = "tcp://xx.xx.xx.xx:6789?persistent=1&timeout=3&database=11&auth=d9cxa2xx67f2xxxxxxxxxxxx58exx5xfxd29"
也不知道你的redis起起来了没,亦不知你的web服务器是否也启动了,有没有异常。redis扩展呢?
楼主的问题问的太大了,就好象用户在问为什么我这个网站打不开,楼主至少把提示什么错误、你是怎么调用的等等这种东西写出来
先确定下你的redis是否需要账号密码,再试下把php配置里面的localhost改成127.0.0.1
其实我比较喜欢使用memcahced 来存储session这类数据!
原因如下:
1.无需设置密码
2.数据结构简单,且响应速度很快
3.做分布式很方便,一台机器专门放session,做共享

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
