在CentOS上配置PHP的SMTP邮件可以通过多种方式实现,以下是使用sendmailphpMailer两种常见方法的详细步骤。

方法一:使用Sendmail配置SMTP邮件

  1. 安装Sendmail

    sudo yum install sendmail sendmail-cf mailx
    
  2. 配置Sendmail 编辑/etc/mail/sendmail.cf文件,添加SMTP服务器信息:

    sudo vi /etc/mail/sendmail.cf
    

    在文件中添加以下内容:

    define(`SMART_HOST', `smtp.yourprovider.com')dnl
    define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
    define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
    define(`confAUTH_OPTIONS', `A p')dnl
    TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
    define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
    
  3. 重启Sendmail服务

    sudo systemctl restart sendmail
    
  4. 测试Sendmail

    echo "Subject: Test Email" | sendmail -v your-email@example.com
    

方法二:使用PHPMailer配置SMTP邮件

  1. 安装PHPMailer 你可以使用Composer来安装PHPMailer:

    composer require phpmailer/phpmailer
    
  2. 编写PHP脚本 创建一个PHP文件(例如send_email.php),并添加以下代码:

    <?php
    use PHPMailer\PHPMailer\PHPMailer;
    use PHPMailer\PHPMailer\SMTP;
    use PHPMailer\PHPMailer\Exception;
    
    require 'vendor/autoload.php';
    
    mailer = new PHPMailer(true);
    
    try {
        // Server settings
        mailer->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
        mailer->isSMTP();                                            // Send using SMTP
        mailer->Host       = 'smtp.yourprovider.com';                     // Set the SMTP server to send through
        mailer->SMTPAuth   = true;                                   // Enable SMTP authentication
        mailer->AuthType   = SMTP::AUTH_LOGIN;                        // Authentication type
        mailer->Port       = 587;                                    // TCP port to connect to; use 465 for `SMTPS`
        mailer->SMTPSecure = SMTP::ENCRYPTION_STARTTLS;         // Enable implicit TLS encryption
        mailer->Username   = 'your-email@example.com';                     // SMTP username
        mailer->Password   = 'your-password';                        // SMTP password
        mailer->SMTPAutoTLS = true;                                 // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
    
        // Recipients
        mailer->setFrom('your-email@example.com', 'Mailer');
        mailer->addAddress('recipient@example.com', 'Recipient Name');     // 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}";
    }
    
  3. 运行PHP脚本

    php send_email.php
    

注意事项

通过以上步骤,你应该能够在CentOS上成功配置PHP的SMTP邮件功能。
