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. Aborting. 2023-06-08T01:08:42.044499Z 0 [ERROR] Aborting

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。
