mysql-5.614-winx64安装包怎么安装
1. MySQL-5.614-Winx64无需安装，只需下载和解压缩即可。
2、将解压缩后的文件放到自己想要的地方，并配置环境变量。例如我存放的目录为：F:\mysql\mysql-5.6.14-winx64
3.修改INI配置文件的解压缩版5.6.14有一个my-default.ini文件。复制在同一级别上更名为my.ini.4。安装服务5.启动服务6.配置用户

单台服务器支持多少socket windows
Windows套接字编程，即单个服务器与多个客户端通信。从类似地说，有多少个Windows插座可以支持单个服务器，该服务器根据操作端口的限制范围而变化，因此没有准确的数量值。例如，操作系统1024的高端数量由系统保留，并且用户使用1024-65535.BESS使用它，因为每个TCP连接都占据了端口号，我们可以拥有多达60,000的并发连接。在实施中。客户端：主线程负责连接服务器，新的子线程用于从服务器接收信息，然后构建一个子线程以将信息从客户端发送到服务器。请理解，单个服务器的过程使用该服务器中的线程与多个客户端进程进行通信。-win
