当你接手某个mysql数据库管理时，首先你需要查看维护的mysql数据库版本；当开发人员问你mysql数据库版本时，而恰好你又遗忘了，那么此时也需要去查看mysql数据库的版本..............。下文总结一下Linux平台下查看mysql数据库的方法.个人觉得总结的比较全面了。
方法1：登录数据库时，你可以看到对应mysql数据库的版本信息，如下所示：
[[email protected] ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.6.19 MySQL Community Server (GPL)

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
mysql>
方法二：使用系统函数查看mysql数据库版本。
mysql> select version();
+-----------+
| version() |
+-----------+
| 5.6.19 |
+-----------+
1 row in set (0.00 sec)
mysql> select @@version;
+-----------+
| @@version |
+-----------+
| 5.6.19 |
+-----------+
1 row in set (0.00 sec)
mysql>
方法3：使用status命令查看,如下所示，查看Server version后内容。
mysql> status

方法4：使用mysql -V命令查看
[[email protected] ~]# mysql -V
mysql Ver 14.14 Distrib 5.6.19, for Linux (x86_64) using EditLine wrapper
[[email protected] ~]# mysql --version
mysql Ver 14.14 Distrib 5.6.19, for Linux (x86_64) using EditLine wrapper
方法5：在mysql --help命令内容中查找
[[email protected] ~]# mysql --help | grep Distrib
mysql Ver 14.14 Distrib 5.6.19, for Linux (x86_64) using EditLine wrapper
方法6：通过rpm命令查看安装包得知mysql数据库版本
[[email protected] ~]# rpm -qa | grep -i mysql
MySQL-client-5.6.19-1.rhel5
MySQL-server-5.6.19-1.rhel5
[[email protected] ~]#
方法7：SHOW VARIABLES 命令查看
mysql> SHOW VARIABLES LIKE "%version%";
+-------------------------+------------------------------+
| Variable_name | Value |
+-------------------------+------------------------------+
| innodb_version | 5.6.19 |
| protocol_version | 10 |
| slave_type_conversions | |
| version | 5.6.19 |
| version_comment | MySQL Community Server (GPL) |
| version_compile_machine | x86_64 |
| version_compile_os | Linux |
+-------------------------+------------------------------+
7 rows in set (0.00 sec)
mysql>
方法8： mysqladmin -uroot -p -hlocalhost version 命令查看mysql数据库版本。其实这个方法也可以归为方法1
[[email protected] ~]# mysqladmin -uroot -p -hlocalhost version;
Enter password:
mysqladmin Ver 8.42 Distrib 5.6.19, for Linux on x86_64
