方法一：

登录子集的mysql之后就会显示mysql版本；

***:~$ mysql -u root -p 
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 40
Server version: 5.5.41-0ubuntu0.14.10.1 (Ubuntu) #这就是版本号

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement

方法二：

　　在你登录之后输入查询语句：select version();

mysql> select version();
+-------------------------+
| version()               |
+-------------------------+
| 5.5.41-0ubuntu0.14.10.1 |

1 row in set (0.00 sec)

mysql> 

就是这么简单；

2.ubuntu下如何知道自己python的版本号：

直接运行'python'就可以查看子集的python版本号；

***:~$ python 
Python 2.7.8 (default, Oct 20 2014, 15:05:19) 
[GCC 4.9.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
