现象：在Windows 10里安装了 Vuze torrent downloader，添加 pthome.net 的种子下载任务后，在任务“来源”中显示 Tracker https://www.pthome.net/announce.php 错误，Offline - SSLHandshakeException: Received fatal alert: handshake_failure，无法开始下载文件。

尝试：在查看 Vuze 版本时，发现 JRE 版本是Vuze安装目录自带的 Vuze/jre 。查看Windows 10中，没有安装JRE。先到Oracle官方网站，下载安装好JRE。之后删除Vuze Torrent Downloader 软件后重新安装。Vuze 重装后首页可以显示引用的网页内容。添加pthome的任务也能正常下载文件了。

现象：运行 bin/magento module:disable Mageplaza_Smtp 命令尝试禁用Magento2模块时，提示出错：

The directory "/var/www/html/generated/code/Magento" cannot be deleted Warning!rmdir(/var/www/html/generated/code/Magento): Directory not empty

尝试：检查发现 /generated 目录及子目录都有文件所有者写权限，删除失败可能是Magento2的定时任务在删除目录的过程中又生成新文件了。可以尝试临时停止Magento2的定时任务或Web进程后再次操作。

需求：不知道哪个模块导致magento2的web进程占用CPU高。

尝试：可以通过禁用、启用模块来尝试诊断。如以下命令会禁用所有非Magento名字头的模块：

php bin/magento module:status | grep -v Magento | grep -v List | grep -v None | grep -v -e '^$'| xargs php bin/magento module:disable

参考：

• https://devdocs.magento.com/guides/v2.3/install-gde/install/cli/install-cli-subcommands-enable.html

需求：magento2程序所在的主机商主动过滤了TCP 25端口的连接，无法通过本机发出电子邮件。

尝试：可以在尝试在magento2里安装模块，通过外部（如QQ、gmail等邮局）SMTP发信。提供该功能的，有：

1. magento-2-smtp - https://github.com/mageplaza/magento-2-smtp
2. gmailsmtpapp - https://github.com/magepal/magento2-gmail-smtp-app
3. SMTP Extension - https://www.magetop.com/magento-2-smtp-extension.html
4. enhanced-smtp - https://github.com/kiwicommerce/magento2-enhanced-smtp

个人觉得在magento2.3上安装了第1、第2和第3，前两种安装成功，但可能与当前的magento2模板有冲突，php或httpd进程的CPU占用率很高。第3个安装不成功，第4个没有安装。最后是通过为本机postfix配置使用smtp relay发出电子邮件。
