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;
    --------------
    mysql  Ver 15.1 Distrib 5.5.47-MariaDB, for Linux (x86_64) using readline 5.1
     
    Connection id:          4
    Current database:
    Current user:           root@localhost
    SSL:                    Not in use
    Current pager:          stdout
    Using outfile:          ''
    Using delimiter:        ;
    Server:                 MariaDB
    Server version:         5.5.47-MariaDB MariaDB Server
    Protocol version:       10
    Connection:             Localhost via UNIX socket
    Server characterset:    latin1
    Db     characterset:    latin1
    Client characterset:    utf8
    Conn.  characterset:    utf8
    UNIX socket:            /var/lib/mysql/mysql.sock

或者

mysql> \s
    --------------
    mysql  Ver 14.14 Distrib 5.6.32, for Win32 (AMD64)
    
    Connection id:          9
    Current database:
    Current user:           root@localhost
    SSL:                    Not in use
    Using delimiter:        ;
    Server version:         5.6.32-log MySQL Community Server (GPL)
    Protocol version:       10
    Connection:             localhost via TCP/IP
    Server characterset:    latin1
    Db     characterset:    latin1
    Client characterset:    gbk
    Conn.  characterset:    gbk
    TCP port:               3307
    Uptime:                 4 hours 9 min 29 sec
    
    Threads: 4  Questions: 144  Slow queries: 0  Opens: 73  Flush tables: 1  Open tables: 66  Queries per second avg: 0.009

以上就是常见的四种mysql查看版本的方法。

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
    Server version: 5.6.32-log MySQL Community Server (GPL)

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