在日常项目开发过程中，我们经常要连接自己的数据库，此时不知道数据库的版本是万万不可的。今天小树懒来给大家总结一下查看mysql版本的方法。
MySQL查看版本的方法主要有以下四种
方法1：
没有连接到MySQL终端下直接使用mysql命令。打开cmd，切换至 MySQL的bin目录，运行以下命令：
[root@localhost lib]# mysql -V
mysql Ver 15.1 Distrib 5.5.47-MariaDB, for Linux (x86_64) using readline 5.1方法2：
同样在终端使用命令
[root@localhost lib]# mysql --help | grep Distrib
mysql Ver 15.1 Distrib 5.5.47-MariaDB, for Linux (x86_64) using readline 5.1方法3：
如果已经连接到了 MySQL ，则可以登陆mysql之后使用内置命令
mysql> select version();
+----------------+
| version() |
+----------------+
| 5.5.47-MariaDB |
+----------------+
1 row in set (0.00 sec)方法4：
同样登录MySQL，使用内置命令
mysql> status;

其实，在命令行连接上MySQL服务器时，其实就已经显示了MySQL的版本，如：
e:\mysql\bin>mysql -uroot -p -P3307
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 10
