使用之前的 MySQL 8.0 的参数文件安装完成 8.0.26 之后发现数据库日志报了 The syntax ‘log_slave_updates’ is deprecated and will be removed in a future release. Please use log_replica_upda tes instead. 等一堆 Warning，具体如下：

毕竟是生产环境，数据库日志报一堆告警也是要处理下，经过查看官方文档 https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-26.html#mysqld-8-0-26-feature 发现从 8.0.26 之后，进行了一些修改。这早在 Jul 1, 2020 MySQL 的官方博客就有了说明：MySQL Terminology Updates https://dev.mysql.com/blog-archive/mysql-terminology-updates/
此 Warning 不影响任何使用，如果要避免，可以按照日志提示将相关参数用新参数替换即可。
