Pentaho BI Server 安裝過程簡述

        爲了安裝這個東西，可真是折騰壞了我，前前後後好幾天，終於今天安裝成功了，今天把安裝過程簡單說一下，強調一下其中遇到的問題，希望可以幫助後來的小夥伴。

        其實安裝還是很簡單的，首先在Pentaho的官方位置下載社區版的server，下載了之後，解壓到一個文件夾就可以了，之後需要安裝JDK，小夥伴注意了，這是個坑啊，java8是不支持的，所以需要安裝java7纔可以，然後就是配置環境變量PATH,JAVA_HOME, PENTAHO_HAVA_HOME,都需要配置，之後，可以在DOS下面測試一下：java -version,,如果可以看到java版本，並且和你指定的路徑是一樣的，就是安裝好了。具體的安裝步驟可以查看上面列出的參考資料，同時將資料粘貼如下。

Install Java

Your steps may vary slightly as I had an older version of the JDK installed. However, the gist is “just click Next till your done”.

1. Download the Java JDK fromhttp://www.oracle.com/technetwork/java/javase/downloads/index.html.
2. After downloading, double-click the installer, which will be named something like: (the name of your file may vary depending on which version you have downloaded)
3. Click Next.
4. Click Next. Wait for the installation to finish.
5. Click Next. Wait for the JRE installation to finish.
6. Click Continue.
7. Click Next to start the JavaFX SDK Setup.
8. Click Next.
9. Click Close.

Add Java to your PATH

You should now have the Java SDK installed into something like (your exact path may vary based on the version):

C:\Program Files\Java\jdk1.7.0_04\bin

1. Click Start.
2. Right-click on Computer, click Properties.
3. In the left pane, click Advanced system settings.
4. Select the Advanced tab, then click Environment Variables…
5. In System Variables, scroll till you find Path.
6. Select Path, click Edit…
7. Add the Java bin folder to  your path by appending ;C:\Program Files\Java\jdk1.7.0_04\bin to the end of the Path Variable Value.
8. Click OK.
9. Click New…
10. In Variable name, enter: PENTAHO_JAVA_HOME
11. In Variable value, enter: C:\Program Files\Java\jdk1.7.0_04
12. Click OK.
13. Click OK.
14. Click OK.

As last step check that your path is set correctly.

1. Open Powershell.
2. Type java -version.
3. Then type javac -version.
4. For each command above, you should see the correct Java version  (for me its 1.7.0_04)
5. Open a command prompt.
6. Type echo %PENTAHO_JAVA_HOME%
7. You should see the following as output: C:\Program Files\Java\jdk1.7.0_04

Note:

If you want to show the value of PENTAHO_JAVA_HOME in PowerShell, then enter:

Get-Childitem env:PENTAHO_JAVA_HOME

Note:

I had to reboot to get this to work.

Install Pentaho BI Server

Now that we have Java installed we can get on with our main task of installing the Pentaho BI Server.

1. Download the Pentaho BI Server fromhttp://wiki.pentaho.com/display/COM/Latest+Stable+Builds. I’m using the current stable build which is biserver-ce-4.5.0-stable.zip.
2. Open Windows Explorer and create new folder: C:\Program Files\Pentaho.
3. Unzip biserver-ce-4.5.0-stable.zip.
4. Next, copy the biserver-ce and administration-console folder into C:\Program Files\Pentaho.

Update the Permissions to allow the server to be run as a developer’s regular user (i.e. not Administrator)

1. In Windows Explorer, navigate to C:\Program Files.
2. Right-click the Pentaho folder, click Properties.
3. Select the Security tab, click Edit.
4. Click Add.
5. Enter the developer’s username, then click OK.
6. In the Allow column, check Full control.
7. Click OK.
8. Click OK.

Start the Pentaho Server

I am not going to cover automatic startup of the Pentaho Server on Windows because my assumption is that some developers choose to run Pentaho on Windows, but that product deployments

1. Open Windows Explorer to C:\Program Files\Pentaho\biserver-ce.
2. Double-click start-pentaho.bat.
3. If the Windows Security Alert dialog box pops up, then click Allow access.

Hint:

I recommend that you resize the command window that displays the Tomcat messages. This will make it easier to read messages that are output by Tomcat.

• In the top left corner of the Window, click the Java icon.
• Click Properties.
• Select the Layout tab.
• Set the Width = 120
• Set the Height = 45
• Click OK.

Login to the Pentaho User Console

1. Open a web browser to http://localhost:8080.
2. Click Evaluation Login and select a user type to login as.

Login to the Pentaho Administration Console

1. Open Windows Explorer to C:\Program Files\Pentaho\administration-console.
2. Double-click start-pac.bat.
3. Open a web browser to http://localhost:8099.
4. Enter a User Name of admin.
5. Enter a Password of password.
6. Click Log In.

That’s it. The core Pentaho BI server is installed and ready for development. However, a good next step is to change the database that Pentaho uses, but we’ll leave that for another post.

------------------------------------------------------------------------------------------------------------------------------------------

There are 3 things you have to take care of:

1. When running on windows, it is easy to run into Windows' path-length limitation. This then will break the jar-loading which in return gives you random errors as the Tomcat server cannot find the classes contained in these jars. So when you install, do not install it deep into a directory, keep it at the root of your disk. From hard experience, I now always install it in DRIVE:\Pentaho

2. The Server will not run without the system database. If your logs show you a Quartz-Error, or a Hibernate error, then your HSQL database is not running. In the download, you'll find a "data" directory. Start the "start-hypersonic.bat" before you start the main Pentaho server.

3. Pentaho does not run with Java 8. There seem to be some incompatible changes in the JDK and I have not been able to actually start it up correctly. You have to use JDK 1.7 to be successful. ALso make sure that your JAVA_HOME or PENTAHO_JAVA_HOME points to the correct JDK.

   The Pentaho bat files try to locate a Java installation automatically, and without explicitly setting these environment variables, any JDK may be picked up at random. Usually that is the last JDK that has been installed or updated. So to be safe, lock down the JDK by setting these variables (via Control Panel-> System -> Advanced System Settings -> Environment Variables)
