mysql - 我需要知道他们是否有 ENTERPRISE 或 COMMUNITY MYSQL 版本

Question

我正在为一家公司做一些 MYSQL 工作，我需要知道他们是否有 ENTERPRISE 或 COMMUNITY 版本。我对此进行了研究，根据 mysql 引用页，我应该可以使用“status”命令。根据该引用，“服务器版本”应该是“社区”或“企业”。我们的都没有说(数字，对吗？)，只是“5.0.77 Source Distribution”。有没有其他方法可以判断？

Answer 1

tl;dr

试试这个:

mysql> SHOW VARIABLES LIKE "%version%";

正常回答

Using a command client (mysql), the server version of the MySQL server to which you are connected is shown once you are connected. The server version information includes community or enterprise accordingly.

For example, here is the output from a MySQL Community Server edition installed on Linux:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 6
Server version: 5.0.27-standard MySQL Community Edition - Standard (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

This is an example of the output from MySQL Enterprise Server on Windows:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.0.28-enterprise-gpl-nt MySQL Enterprise Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

You may also determine the version information using the version variables. Both the version and version_comment variables contain version information for the server to which you are connected. Use the SHOW VARIABLES statement to obtain the information you want, as shown in this example:

mysql> SHOW VARIABLES LIKE "%version%";
+-------------------------+------------------------------------------+
| Variable_name           | Value                                    |
+-------------------------+------------------------------------------+
| protocol_version        | 10                                       |
| version                 | 5.0.27-standard                          |
| version_comment         | MySQL Community Edition - Standard (GPL) |
| version_compile_machine | i686                                     |
| version_compile_os      | pc-linux-gnu                             |

Straight from the documentation .

当然，STATUS 也是如此；

The STATUS command displays the version as well as version comment information. For example:

mysql> STATUS;
--------------
./client/mysql  Ver 14.12 Distrib 5.0.29, for pc-linux-gnu (i686) using     readline 5.0

所以我想知道您是否真的只是在查看提供的第一行，或者您是否正在检查下面的“服务器版本”行。

如你found out似乎他们没有在版本之间进行讨论，因为它是一个特定版本的版本，在本例中是一个社区版。因此，答案通常只有在您无法通过查找版本确定时才有效。
