随着 PHP 开发环境的普及，越来越多的企业和开发者希望在 Linode 提供的虚拟专用服务器（VPS）上运行自己的 PHP 应用程序，将 PHP 应用程序部署到 Linode VPS 上时，安全性和配置的正确性至关重要，以避免潜在的漏洞和攻击风险，以下是一些关键步骤和最佳实践，帮助您在 Linode VPS 上安全地发布 PHP 应用程序。
安装 PHP 和必要的依赖项
您需要确保 Linode VPS 上已经安装了 PHP 以及必要的开发工具和依赖项，以下是操作步骤：
-
安装 PHP：
您可以通过以下命令在 Linode VPS 上安装 PHP：sudo apt-get update && sudo apt-get install php7.4
这将安装 PHP 7.4 版本，这是当前主流版本。
-
安装 PHPUnit 和 Predis：
PHPUnit 和 Predis 是 PHP 中的常用工具，用于 PHPUnit 测试框架和数据库集成，安装它们的命令如下：sudo apt-get install phptunit php-predis
-
验证安装：
安装完成后，您可以运行以下命令来验证 PHP 是否正确安装：php --version
如果输出显示安装了正确的版本（如
PHP 7.4.20），则表示安装成功。
配置 PHP 环境
在 Linode VPS 上运行 PHP 应用程序时，配置环境以确保应用能够正常运行。
-
选择 PHP 版本：
根据您的应用需求，选择合适的 PHP 版本，默认情况下，Linode VPS 可能会自动配置 PHP 版本，但您也可以手动指定：php-config --version
如果输出显示当前配置的版本,可以使用：
php-config --version | grep -i 7.4
如果没有 7.4 版本，可以重新安装并配置。
-
配置 PHP 配置文件：
您的应用程序需要根据项目的具体需求配置 PHP 配置文件，这些配置文件位于/etc/php/目录下。php.ini文件用于设置默认选项，config.php可以用于项目特定的配置。 -
启用安全选项：
为了确保应用的安全性，启用 PHP 的安全选项，在php.ini中添加以下内容：# 首行注释 # PHP.ini # 打开 php.ini # 禁用自动登录 security_start automate logon=no # 禁用 SQL 注入 security_start allow_sql injections=no # 禁用 eval security_start allow_eval=no # 禁用文件包含 security_start allow_file_includes=no # 禁用默认安全头 security_start default_headers off # 配置安全头 security_start allow_headers on security_start allow_headers all security_start
