mysql jdbc驱动下载及查看mysql的端口号

mingwjj

一:查看mysql的端口号
在你的my.ini(Windows)或my.cfg(Linux) 中啊。
或者如果已经连入MySQL可以直接
SQL code
mysql> show variables like 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)
mysql>
3306 是默认端口。
二:四种查看版本的方法1：在终端下：mysql -V。
以下是代码片段：
[shengting@login ~]$ mysql -V
mysql  Ver 14.7 Distrib 4.1.10a, for redhat-linux-gnu (i686)
    2：在mysql中：mysql> status;
以下是代码片段：
mysql> status;
--------------
mysql  Ver 14.7 Distrib 4.1.10a, for redhat-linux-gnu (i686)
Connection id:          416

Threads: 1  Questions: 584402560  Slow queries: 424  Opens: 59664208  Flush tables: 1  Open tables: 64 Queries per second avg: 107.551
    3：在help里面查找
以下是代码片段：
[shengting@login ~]$ mysql --help | grep Distrib
mysql  Ver 14.7 Distrib 4.1.10a, for redhat-linux-gnu (i686)
    4：使用mysql的函数
以下是代码片段：
mysql> select version();
+-------------+
| version()   |
+-------------+
| 3.23.56-log |
+-------------+
1 row in set (0.00 sec)
