在CentOS上配置PHP以使用SMTP发送邮件,通常需要以下几个步骤:

  1. 安装PHPMailer: PHPMailer是一个流行的PHP库,用于发送电子邮件。你可以使用Composer来安装它。

    sudo yum install php-composer
    composer require phpmailer/phpmailer
    
  2. 配置PHPMailer: 创建一个新的PHP文件来配置和使用PHPMailer发送邮件。例如,创建一个名为sendmail.php的文件:

    <?php
    use PHPMailer\PHPMailer\PHPMailer;
    use PHPMailer\PHPMailer\Exception;
    
    require 'vendor/autoload.php';
    
    mailer = new PHPMailer(true);
    
    try {
        // Server settings
        mailer->SMTPDebug = 2;                                      // Enable verbose debug output
        mailer->isSMTP();                                           // Send using SMTP
        mailer->Host       = 'smtp.example.com';                     // Set the SMTP server to send through
        mailer->SMTPAuth   = true;                                   // Enable SMTP authentication
        mailer->AuthType   = 'XOAUTH2';                              // OAuth2 authentication (if supported by your SMTP server)
        mailer->Port       = 587;                                    // TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`
        mailer->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable implicit TLS encryption
    
        // Credentials
        mailer->OAuthUserEmail = 'your-email@example.com';            // Your email address
        mailer->OAuthClientId  = 'your-client-id';                   // Your OAuth client ID
        mailer->OAuthClientSecret  = 'your-client-secret';             // Your OAuth client secret
        mailer->OAuthRefreshToken  = 'your-refresh-token';             // Your OAuth refresh token
    
        // Recipients
        mailer->setFrom('from@example.com', 'Mailer');
        mailer->addAddress('recipient@example.com', 'Joe User');     // Add a recipient
    
        // Content
        mailer->isHTML(true);                                        // Set email format to HTML
        mailer->Subject = 'Here is the subject';
        mailer->Body    = 'This is the HTML message body <b>in bold!</b>';
        mailer->AltBody = 'This is the body in plain text for non-HTML mail clients';
    
        mailer->send();
        echo 'Message has been sent';
    } catch (Exception $e) {
        echo "Message could not be sent. Mailer Error: {$mailer->ErrorInfo}";
    }
    

    请将smtp.example.comyour-email@example.comyour-client-idyour-client-secretyour-refresh-token替换为你的SMTP服务器信息和OAuth凭据。

  3. 运行PHP脚本: 在终端中运行你的PHP脚本来测试邮件发送功能:

    php sendmail.php
    

    如果一切配置正确,你应该会看到消息“Message has been sent”。

注意事项

通过以上步骤,你应该能够在CentOS上成功配置PHP以使用SMTP发送邮件。
