如果已经进入到Mysql环境，办法有两个：
法一：
mysql> status; -------------- mysql Ver 14.14 Distrib 5.5.24, for osx10.6 (i386) using readline 5.1 Connection id: 471 Current database: test Current user: root@localhost SSL: Not in use Current pager: stdout Using outfile: '' Using delimiter: ; Server version: 5.5.24 MySQL Community Server (GPL) Protocol version: 10 Connection: Localhost via UNIX socket Server characterset: latin1 Db characterset: utf8 Client characterset: utf8 Conn. characterset: utf8 UNIX socket: /tmp/mysql.sock Uptime: 6 days 15 min 32 sec Threads: 2 Questions: 4008 Slow queries: 0 Opens: 189 Flush tables: 1 Open tables: 154 Queries per second avg: 0.007 --------------
法二：
mysql> select version(); +-----------+ | version() | +-----------+ | 5.5.24 | +-----------+ 1 row in set (0.06 sec)
如果还未进入工作环境，可以如下：
法一：
localhost-6:~ root$ mysql -V mysql Ver 14.14 Distrib 5.5.24, for osx10.6 (i386) using readline 5.1
法二：
localhost-6:~ root$ mysql --help mysql Ver 14.14 Distrib 5.5.24, for osx10.6 (i386) using readline 5.1 Copyright (c) 2000, 2011, Oracle and/or its affiliates. All rights reserved.
