If you're already logged into the command line client try this:

<pre><code>mysql&gt; select user();
</code></pre>

It will output something similar to this:

<pre><code>+----------------+
| user() |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.41 sec)
</code></pre>

In my example above, I was logged in as <code>root</code> from <code>localhost</code>.

To find port number and other interesting settings use this command:

<pre><code>mysql&gt; show variables;
</code></pre>

For Example in my case : <code>karola-pc</code> is the host name of the box where my mysql is running. And it my local PC host name. 

If it is romote box than you can ping that host directly if, If you are in network with that box you should be able to ping that host.

If it <code>UNIX or Linux you can run "hostname" command</code> in terminal to check the host name.
if it is windows you can see same value in <code>MyComputer-&gt; right click -&gt; properties -&gt;Computer Name</code> you can see ( i.e System Properties) 

Hope it will answer your Q.

I need to find my MySQL username. When I open the MySQL command line client, it only asks me for my password. I don't remember my username. And for connectivity with JDBC, I need the URL, host and port number. Where do I find all of these?

How do I find out my MySQL URL, host, port and username?

服务器

MySQL

Linux

我需要找到我的MySQL用户名。当我打开MySQL命令行客户端时，它只要求我输入密码。我不记得我的用户名了。为了与JDBC连接，我需要URL、主机和端口号。我在哪里可以找到所有这些？
