當你接手某個mysql數據庫管理時，首先你需要查看維護的mysql數據庫版本；當開發人員問你mysql數據庫版本時，而恰好你又遺忘了，那麼此時也需要去查看mysql數據庫的版本..............。下文總結一下Linux平台下查看mysql數據庫的方法.個人覺得總結的比較全面了。
方法1：登錄數據庫時，你可以看到對應mysql數據庫的版本信息，如下所示：
[root@DB-Server ~]# 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)

owners.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
方法二：使用系統函數查看mysql數據庫版本。
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後內容。
mysql> status

--------------
方法4：使用mysql -V命令查看
[root@DB-Server ~]# mysql -V
mysql Ver 14.14 Distrib 5.6.19, for Linux (x86_64) using EditLine wrapper
[root@DB-Server ~]# mysql --version
mysql Ver 14.14 Distrib 5.6.19, for Linux (x86_64) using EditLine wrapper
方法5：在mysql --help命令內容中查找
[root@DB-Server ~]# mysql --help | grep Distrib
mysql Ver 14.14 Distrib 5.6.19, for Linux (x86_64) using EditLine wrapper
方法6：通過rpm命令查看安裝包得知mysql數據庫版本
[root@DB-Server ~]# rpm -qa | grep -i mysql
MySQL-client-5.6.19-1.rhel5
MySQL-server-5.6.19-1.rhel5
[root@DB-Server ~]#
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數據庫版本。其實這個方法也可以歸為方法1
[root@DB-Server ~]# mysqladmin -uroot -p -hlocalhost version;
Enter password:
mysqladmin Ver 8.42 Distrib 5.6.19, for Linux on x86_64

進入mysql後輸入 \s 查看版本信息希望這些對你有幫助。很好,2011/9/26 14:59:43
