Trying to log queries to stdout doesn't work below,

尝试将查询记录到stdout在下面不起作用，

$ mysqld --general_log=1 --general_log_file=/dev/stdout

You can't, not directly. The query logs only go to files, tables or nowhere. They don't seem to go to /dev/stdout nor honor the - convention. Don't worry, there's a much better way.

你不能，不能直接。查询日志只会转到文件，表或任何地方。他们似乎没有去/ dev / stdout，也没有遵守 - 惯例。别担心，有一个更好的方法。

If all you want to do is see the query log as it happens, you can stream the log file using various Unix utilities. tail -f is one option.

如果您只想查看查询日志，则可以使用各种Unix实用程序来传输日志文件。 tail -f是一种选择。

tail -f /path/to/query.log

I prefer opening the log with less and using the F command to keep reading as the file is added to. It's like tail -f but you can also scroll around and search the file.

我更喜欢用less打开日志，并使用F命令在添加文件时继续读取。它就像tail -f但你也可以滚动并搜索文件。

$ less /path/to/query.log
