这个错误提示表明在尝试通过API发送电子邮件时,出现了连接问题。具体来说,SMTP服务器没有成功地向API发送方发送问候消息。这可能是因为SMTP服务器无法访问或无响应,或者由于网络连接问题导致连接中断。
要解决这个问题,可以尝试以下步骤:
1. 检查SMTP服务器是否正常工作,并确保可以从API服务器访问它。
2. 检查网络连接是否正常,并确保API服务器可以与SMTP服务器进行通信。
3. 确认API代码是否正确配置了SMTP服务器的参数,包括服务器地址、端口号、用户名和密码等。
4. 尝试使用其他SMTP服务器进行测试,以确定是SMTP服务器本身还是API代码的问题。
如果这些步骤都没有解决问题,可以考虑查看API日志文件,以获取更多有关错误的信息,并寻求进一步的技术支持。

这段日志是一个 MySQL 集群中的一台机器(DONOR)在进行 SST(State Snapshot Transfer)时出现了错误。从日志中可以看到,xtrabackup_checkpoints 文件缺失导致 SST 失败,需要检查 DONOR 日志文件,以找到原因。因为 SST 失败,其他节点(joiner)无法接收状态,集群需要终止。最后,WSREP 进程由于遇到错误而退出。
D:\MySQL\bin>mysqld --initialize 2023-06-08T01:08:42.040878Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2023-06-08T01:08:42.043919Z 0 [ERROR] --initialize specified but the data directory has files in it.

您在执行mysqld --initialize时遇到了错误。错误信息显示数据目录中已经存在文件,因此初始化操作无法执行。您可以尝试使用以下命令创建一个空的数据目录并重新执行初始化操作:
```
mkdir D:\MySQL\data
cd D:\MySQL\bin
mysqld --initialize-insecure --datadir=D:\MySQL\data
```
注意,在上述命令中,--initialize-insecure选项将跳过密码生成步骤,直接创建一个空的MySQL实例。如果您需要设置密码,请使用--initialize选项并按照提示进行操作。
