系统Windows 7 sp1 64位,搭建32位服务器,以下软件都选择32位vc11运行时zip包,软件需要vc11运行时的支持,官方网址(vc11 update 4) http://www.microsoft.com/en-us/download/details.aspx?id=30679 下载32位版。
Apache 2.4.12
Apache Http Server 官方只提供源代码(http://httpd.apache.org/docs/current/platform/windows.html#down)下载地址 http://www.apachehaus.com/cgi-bin/download.plx
PHP 5.5.23
PHP for Windows分TS和NTS(线程安全,没有线程安全),搭配Apache的是要TS的版本。下载地址 http://windows.php.net/index.php
MySQL 5.6.23
免费的选 Community版本。下载地址 http://dev.mysql.com/downloads/mysql/
phpMyAdmin 4.3.13
通过 web 界面操作数据库的开源工具,一般都要用。下载地址 http://www.phpmyadmin.net/home_page/downloads.php
配置 Apache,配置文件 httpd.conf,Define SRVROOT "/Apache24" 改为存放 apache 的绝对地址,正常的话启动apache打开浏览器就可以看到 “it works” 的默认页面。
加载 PHP 需要在配置文件中添加一些信息
PHPIniDir "x:/xxx/xxx/php55"
LoadModule php5_module "x:/xxx/xxx/php55/php5apache2_4.dll"
配置 PHP,复制 php.ini-development 到 php.ini,修改 extension_dir 为 ext 的绝对路径,打开需要的扩展。
php_curl 有点问题无法加载,curl 依赖 openssl,php 由 apache 加载,apache 目录下有同样的 openssl 版本。估计是模块本身的设置吧,替换 php_curl.dll 文件解决,参考 http://stackoverflow.com/questions/10939248/php-curl-not-working-wamp-on-windows-7-64-bit/10977022.
php_ldap 也无法正常开启,ldap 依赖 openssl 以及 libsasl,因为 libsasl 在 php 目录下,可以指定 apache 加载,在 httpd.conf 中添加 Loadfile
"xxxxxx/php55/libsasl.dll"(libsasl.dll的绝对路径)解决,也可以拷贝 libsasl 到系统路径解决
MySQL 复制 my-default.ini 到 my.ini,修改绝对路径
basedir = mysql 的绝对路径
datadir = mysql 数据的存放路径
另外还有个 myPhpAdmin,复制 config.simple.inc到config.inc,修改 $cfg['blowfish_secret'] = 'xxx'; (任意字符)
This is needed for cookie based authentication to encrypt password in cookie
没什么问题后就可以用 phpMyAdmin 登录数据库了,新版的工具不允许 root 空密码,所以想要设置 mysql root 密码

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
