+# Ruby连接 OceanBase 指南（mysql2）
+
+[English](README.md) | 简体中文
+
+本文介绍如何通过 mysql2驱动连接 OceanBase 数据库。
+
+## 快速开始
+
+在开始之前，需要先确保 mysql2已安装。
+
+安装命令
+
+```
+gem install mysql2
+```
+
+以 [example.rb](example.rb) 为例。
+
+```python
+require 'mysql2'
+
+def connect_to_oceanbase(host, port, username, password, database)
+  begin
+    # 创建数据库连接
+    client = Mysql2::Client.new(
+      host: host,
+      port: port,
+      username: username,
+      password: password,
+      database: database
+    )
+
+    puts "连接到OceanBase数据库成功"
+
+    # 执行一个简单的查询
+    results = client.query("SELECT DATABASE();")
+
+    results.each do |row|
+      puts "连接到的数据库: #{row['DATABASE()']}"
+    end
+
+    # 你可以在这里执行其他的SQL查询或操作
+
+    client.close
+    puts "MySQL连接已关闭"
+
+  rescue Mysql2::Error => e
+    puts "连接到OceanBase数据库失败: #{e.error}"
+  end
+end
+
+if __FILE__ == $0
+  connect_to_oceanbase(
+    '127.0.0.1',
+    2881,
+    'root',
+    'password',
+    'test'
+  )
+end
+
+```
+
+修改代码中的连接信息，之后你就可以直接使用命令行运行示例代码。
+
+```bash
+ruby  example.rb
+```

+# Ruby Connection OceanBase Guide (Mysql2)
+
+English | [简体中文](README-CN.md)
+
+This article introduces how to connect to OceanBase database through mysql2 driver.
+
+## Quick Start
+
+Before starting, it is necessary to ensure that mysql2 is installed.
+
+Installation command
+
+```
+gem install mysql2
+```
+
+Taking [example.rb](example.rb)  as an example.
+
+```python
+require 'mysql2'
+
+def connect_to_oceanbase(host, port, username, password, database)
+  begin
+    # 创建数据库连接
+    client = Mysql2::Client.new(
+      host: host,
+      port: port,
+      username: username,
+      password: password,
+      database: database
+    )
+
+    puts "连接到OceanBase数据库成功"
+
+    # 执行一个简单的查询
+    results = client.query("SELECT DATABASE();")
+
+    results.each do |row|
+      puts "连接到的数据库: #{row['DATABASE()']}"
+    end
+
+    # 你可以在这里执行其他的SQL查询或操作
+
+    client.close
+    puts "MySQL连接已关闭"
+
+  rescue Mysql2::Error => e
+    puts "连接到OceanBase数据库失败: #{e.error}"
+  end
+end
+
+if __FILE__ == $0
+  connect_to_oceanbase(
+    '127.0.0.1',
+    2881,
+    'root',
+    'password',
+    'test'
+  )
+end
+
+```
+
+Modify the connection information in the code, and then you can directly run the example code using the command line.
+
+```bash
+ruby  example.rb
+```
