如果没有任何区别,为什么有两个服务器参数来实现一种行为呢?
log_slow_queries was deprecated in MySQL 5.1.29 by slow-query-log.
The MySQL 5.1 Reference Manual has more details.
从 Mysql 文件 :
The --log-slow-queries option is deprecated and is removed (along with the log_slow_queries system variable) in MySQL 5.6. Instead, use the --slow_query_log option to enable the slow query log and the --slow_query_log_file=file_name option to set the slow query log file name.
