試してみた
環境
試してみた OS は CentOS 7.2 です
# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
インストール
RedHat系OSの場合、Microsoft が提供する Yum リポジトリからインストールできます。インストール手順はInstall SQL Server on Red Hat Enterprise Linuxをご参照ください。
まずは Yum リポジトリの定義をダウンロードします。/etc/yum.repos.d/に配置します。
# curl https://packages.microsoft.com/config/rhel/7/mssql-server.repo > /etc/yum.repos.d/mssql-server.repo
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

baseurl=https://packages.microsoft.com/rhel/7/mssql-server/
enabled=1
gpgcheck=1
gpgkey=https://packages.microsoft.com/keys/microsoft.asc
yum コマンドでインストールします。

初期セットアップコマンドを実行します。セットアップは対話形式となり、ライセンスの承諾（YES）、管理者アカウントパスワード、サービス起動、自動起動を設定します。

サービスのステータスを確認します。
systemctl status mssql-server

起動していますね。
必要に応じて、firewalld のポートを開放します。SQL Server はデフォルト 1433/tcp でアクセスを受けます。
# firewall-cmd --zone=public --add-port=1433/tcp --permanent success # firewall-cmd --reload success # firewall-cmd --list-all public (default, active) interfaces: enp0s3 sources: services: dhcpv6-client ssh ports: 1433/tcp masquerade: no forward-ports: icmp-blocks: rich rules:
インストールは以上です。機能が絞られているからか Windows Server へのインストールに比べ非常に早くインストール〜起動までを行うことができます。
接続・操作
SQL Server の操作は Management Studio で操作する印象が強いですが、別途CLIツールも提供しています。こちらも Yum リポジトリからインストールできます。
まず、Yum リポジトリの定義ファイルをダウンロードします。
# curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/msprod.repo

yum コマンドでインストールします。2回ライセンスの承諾でYESを入力する必要があります。

sqlcmdコマンドを利用して、接続することができます。
# sqlcmd -S localhost -U SA -P '<YourPassword>' 1>
接続できました。
いくつかクエリを試してみます。
データベースの確認
1> select name from sys.Databases; 2> go name -------------------------------------------------------------------------------------------------------------------------------- master tempdb model msdb (4 rows affected)
データベースの作成
1> CREATE DATABASE db; 2> go 1> select name from sys.Databases 2> go name -------------------------------------------------------------------------------------------------------------------------------- master tempdb model msdb testdb (5 rows affected)
テーブル作成
1> use testdb 2> go Changed database context to 'testdb'. 1> CREATE TABLE inventory (id INT, name NVARCHAR(50), quantity INT) 2> go 1> select name from sys.tables; 2> go name -------------------------------------------------------------------------------------------------------------------------------- inventory (1 rows affected)
データ挿入
1> INSERT INTO inventory VALUES (1, 'banana', 150);
2> INSERT INTO inventory VALUES (2, 'orange', 154);
3> go
(1 rows affected)
(1 rows affected)
1> select * from inventory
2> go
id name quantity
----------- -------------------------------------------------- -----------
1 banana 150
2 orange 154
(2 rows affected)
もちろん Management Studio からも接続できます。
まとめ
いかがでしたでしょうか？
正直まだ SQL Server on Linux の使い処が見えていませんが、社会人一年目に初めて SQL Server をインストールした時は設定項目の多さに大変苦労しましたが、このインストールの容易さは SQL Server の利用の敷居は下がったように感じました。今回の「Connect();// 2016」では The Linux Foundation への加入や、Visual Studio for Mac のリリースと今までのMicrosoftにない試みがたくさん発表されたように感じました。
