1. 始める前に

以下の点を確認してください：

Ensure that your system meets the minimum requirements to run Confluence. For more information, please read the detailed System Requirements.
Have your Confluence license key ready. You can obtain a trial, free or commercial license, or retrieve your existing license key at my.atlassian.com.
コマンドプロンプトを使用して継続し、Java をインストールする必要があります。
Make sure that you use a Gnu version of zip application - Solaris and AIX are known to have problems with zip, because they use their own (old) versions instead of the Gnu version.

2. Java をインストール

Please refer to the Supported Platforms for the required version of Java. (OpenJDK is currently not supported)

Java が正しくインストールされているか分からない場合、次の操作を行って確認してください：

シェルコンソールを開く。
Type echo $JAVA_HOME in the shell console and then press Enter
結果を確認します:
- If a line is displayed such as /opt/jdk1.8.0_45 or /usr/lib/jvm/java-8-sun, then Java is installed and properly configured.
- If nothing is displayed, then you either need to install Java or set the $JAVA_HOME environment variable. You can set this environment variable in your user account's 'profile' file. Alternatively, you can set this after installing Confluence (in step 4 below) by defining this path in your Confluence installation's setenv.sh file, usually located in the Confluence bin directory.

Java のインストールが必要な場合は、次の説明にしたがってください：

Go to the Java download page and download the latest JRE or JDK that is listed on the Confluence Supported Platforms page. (Confluence works with either the JDK or the JRE.)
When the download has finished, run the Java installer. Detailed installation instructions are provided on Oracle's website.
Note: you will be asked to choose an installation directory. Make a note of this directory, you'l' need it later.

3. Confluence インストールファイルをダウンロードおよび抽出

If you have not downloaded Confluence already, download the TAR.GZ file.

Use your unzip program to unzip the installation file to a directory such as /home/jsmith/confluence-2.7.0-std/.

Most Linux/Solaris users can use any unzip program (such as GNU Tar) to extract the Confluence installer. However, Solaris users should not use the Solaris Tar program due to a known issue associated with its use in extracting Confluence. Use another application such as GNU Tar instead.

例えば、Linux でディレクトリをホームディレクトリに変更し、シェルコンソールで以下のコマンドを入力します：

- gunzip confluence-<version>-std.tar.gz
- tar -xf confluence-<version>-std.tar
  (where <version> refers to the Confluence version you downloaded.)

Linux/Solaris ベースの OS では、通常、ご利用のディレクトリパスのスペースの使用を避けます。解凍した Confluence インストールファイルの保存先となるディレクトリを Confluence インストールディレクトリと呼びます。次に、Confluence ホームディレクトリを定義します。

4. Confluence ホームディレクトリを定義します。

Now you need to define the Confluence Home directory. This is where Confluence will store its configuration information, indexes and attachments. Another term for 'Home directory' would be 'data directory'.

インストールディレクトリとホームディレクトリには別々のパスを使用することをお勧めします。アップグレードが容易になります。インストールディレクトリとホームディレクトリの例：

Installation directory: /usr/local/confluence/
If you wish to install or maintain multiple versions of Confluence, you can add a version number to the Confluence installation directory name like /usr/local/confluence-3.1-std/ and optionally, create the symbolic link /usr/local/confluence/ that points to /usr/local/confluence-3.1-std/

Home directory: /usr/local/confluence-data/

Open your Confluence Installation directory (created when you unzipped Confluence — see above).
Under the Installation directory, find this file: confluence/WEB-INF/classes/confluence-init.properties
Open the confluence-init.properties file in a text editor.
このラインまでスクロールします：
# confluence.home=c:/confluence/data
Remove the '#' and the space at the beginning of this line, so that Confluence no longer regards the line as a comment. The line should now begin with confluence.home
Confluence ホームディレクトリをデフォルトから変更する場合は、記号リンクではなく絶対パスを使用してパスとファイル名を指定します。例：
confluence.home=/home/jsmith/confluence-data/

5. ポートの確認

If you have another application running on your machine which is using the same ports that Confluence uses by default, you may need to change the port which Confluence will use. For example, if you have a JIRA application running on this machine, JIRA might be already using the port which Confluence requests by default.

デフォルトでは、Confluence はポート『8090』をリッスンします。もしこのポートがインストールディレクトリですでに使用されている場合は、以下の説明にしたがってポートを変更してください：

You will find more information on this page.

6. データベースの選定

This step is optional for users evaluating Confluence. However, if you are installing Confluence for production purposes, this step is mandatory. Please refer to the database requirements listed on our System Requirements topic for help in choosing an external database.

External databases are those listed on our Supported Platforms topic, excluding HSQLDB, which is bundled with Confluence and should not be used in production.

When you have chosen your external database, follow the appropriate database setup guide to set up your database to work with Confluence.

You can learn more about migration from an existing installation or use of the evaluation database here. You will continue to use the Database Setup Guide during the Confluence Setup Wizard. (See step 8 below.)

7. Confluence の起動

Go to your Confluence Installation directory (created when you unzipped Confluence — see above).
Under your Confluence Installation directory, open the bin directory and run the startup script: start-confluence.sh.
Once Confluence is running, open a web browser and visit http://localhost:8090/.
Hint: If you changed the port earlier, use the port you specified in step 6 above.

8. Confluence セットアップウィザード

The Confluence Setup Wizard should appear in your web browser, prompting you to enter your license key. Follow the instructions on the screens, and read more guidelines on the Confluence Setup Wizard.
