PHP远程连接MySQL数据库的理论基础** PHP远程连接MySQL数据库是指在本地PHP脚本中访问位于远程服务器上的MySQL数据库。这种连接方式需要建立网络连接,并使用MySQL客户端库(如MySQLi或PDO)进行通信。 远程连接MySQL数据库涉及几个关键概念: * **客户端-服务器模型:**PHP脚本充当客户端,连接到运行MySQL数据库的服务器。 * **网络连接:**客户端和服务器通过网络(如互联网或局域网)建立连接。 * **MySQL客户端库:**PHP客户端库提供了与MySQL服务器通信的接口,允许执行SQL查询和管理数据库。 # 2. PHP远程连接MySQL数据库的实践技巧 ### 2.1 Docker容器部署MySQL数据库 #### 2.1.1 Docker容器的基本概念和安装 Docker容器是一种轻量级的虚拟化技术,它允许在单个主机上运行多个独立的应用程序。Docker容器与传统虚拟机相比,具有启动速度快、资源消耗低等优点。 要使用Docker容器,需要在主机上安装Docker引擎。可以从Docker官方网站下载并安装Docker引擎。 #### 2.1.2 创建和启动MySQL Docker容器 创建MySQL Docker容器的命令如下: ``` docker run -d --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password mysql:latest ``` 该命令将创建一个名为`mysql`的Docker容器,并将其映射到主机上的3306端口。同时,它还将设置MySQL root用户的密码为`password`。 启动容器后,可以使用以下命令连接到MySQL容器: ``` docker exec -it mysql bash ``` ### 2.2 PHP连接MySQL Docker容器 #### 2.2.1 PHP MySQL扩展的安装和配置 要使用PHP连接MySQL数据库,需要安装PHP MySQL扩展。可以使用以下命令安装扩展: ``` sudo apt-get install php-mysql ``` 安装扩展后,需要在php.ini文件中启用扩展。找到以下行并将其取消注释: ``` ;extension=mysqli ``` #### 2.2.2 PHP连接MySQL Docker容器的代码示例 连接到MySQL Docker容器的PHP代码示例如下: ```php <?php $servername = "mysql"; $username = "root"; $password = "password"; $dbname = "mydb"; // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检查连接 if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } echo "连接成功"; ?> ``` ### 2.3 远程访问MySQL Docker容器 #### 2.3.1 端口映射和防火墙配置 要远程访问MySQL Docker容器,需要在主机上映
