你可以很容易地将每个查询记录到日志文件中:

mysql> SHOW VARIABLES LIKE "general_log%";

+------------------+----------------------------+
| Variable_name    | Value                      |
+------------------+----------------------------+
| general_log      | OFF                        |
| general_log_file | /var/run/mysqld/mysqld.log |
+------------------+----------------------------+

mysql> SET GLOBAL general_log = 'ON';

执行查询(在任何db上)。查看/var/run/mysqld/mysqld.log

那就别忘了

mysql> SET GLOBAL general_log = 'OFF';

否则，性能将急剧下降，磁盘将被填满!

尽管答案已经被接受，但我想提出一个可能是最简单的选择:

$ mysqladmin -u bob -p -i 1 processlist

这将每秒钟在屏幕上打印当前查询。

-u执行命令的mysql用户名 -p提示输入你的密码(这样你就不必把它保存在一个文件中或让命令出现在你的命令历史中) i以秒为单位的间隔。 使用——verbose标志显示完整的进程列表，显示每个进程的整个查询。(谢谢,nmat)

这可能有一个缺点:如果快速查询在您设置的时间间隔之间运行，则可能不会显示。IE:我的间隔设置为1秒，如果有一个查询需要0.02秒才能运行，并且在间隔之间运行，您将看不到它。

当您希望快速检查正在运行的查询而无需设置侦听器或其他任何东西时，最好使用此选项。

我一直想做同样的事情，并从各种帖子中拼凑出了一个解决方案，再加上创建了一个小的控制台应用程序来输出实时查询文本，因为它被写入日志文件。这在我的情况下是重要的，因为我使用实体框架与MySQL，我需要能够检查生成的SQL。

创建日志文件的步骤(一些其他帖子的复制，这里都是为了简单起见):

Edit the file located at: C:\Program Files (x86)\MySQL\MySQL Server 5.5\my.ini Add "log=development.log" to the bottom of the file. (Note saving this file required me to run my text editor as an admin). Use MySql workbench to open a command line, enter the password. Run the following to turn on general logging which will record all queries ran: SET GLOBAL general_log = 'ON'; To turn off: SET GLOBAL general_log = 'OFF'; This will cause running queries to be written to a text file at the following location. C:\ProgramData\MySQL\MySQL Server 5.5\data\development.log Create / Run a console app that will output the log information in real time: Source available to download here Source: using System; using System.Configuration; using System.IO; using System.Threading; namespace LiveLogs.ConsoleApp { class Program { static void Main(string[] args) { // Console sizing can cause exceptions if you are using a // small monitor. Change as required. Console.SetWindowSize(152, 58); Console.BufferHeight = 1500; string filePath = ConfigurationManager.AppSettings["MonitoredTextFilePath"]; Console.Title = string.Format("Live Logs {0}", filePath); var fileStream = new FileStream(filePath, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite); // Move to the end of the stream so we do not read in existing // log text, only watch for new text. fileStream.Position = fileStream.Length; StreamReader streamReader; // Commented lines are for duplicating the log output as it's written to // allow verification via a diff that the contents are the same and all // is being output. // var fsWrite = new FileStream(@"C:\DuplicateFile.txt", FileMode.Create); // var sw = new StreamWriter(fsWrite); int rowNum = 0; while (true) { streamReader = new StreamReader(fileStream); string line; string rowStr; while (streamReader.Peek() != -1) { rowNum++; line = streamReader.ReadLine(); rowStr = rowNum.ToString(); string output = String.Format("{0} {1}:\t{2}", rowStr.PadLeft(6, '0'), DateTime.Now.ToLongTimeString(), line); Console.WriteLine(output); // sw.WriteLine(output); } // sw.Flush(); Thread.Sleep(500); } } } }

Gibbs MySQL Spyglass

AgilData最近推出了Gibbs MySQL可伸缩性顾问(一个免费的自助服务工具)，它允许用户捕获实时查询流并上传到Gibbs。Spyglass(它是开源的)将监视MySQL服务器和客户端应用程序之间的交互。不需要重新配置或重新启动MySQL数据库服务器(无论是客户端还是应用程序)。

GitHub: AgilData / gibbs-mysql-spyglass

安装命令:

curl -s https://raw.githubusercontent.com/AgilData/gibbs-mysql-spyglass/master/install.sh | bash

除了前面描述如何启用一般日志记录的答案之外，在将任何SQL写入日志之前，我必须在我的香草MySql 5.6安装中修改一个额外的变量:

SET GLOBAL log_output = 'FILE';

默认设置为“NONE”。
