Flowable UI應用安裝（Flowable UI application installation）

As mentioned before, the UI application can be deployedon a Tomcat server, and to get started this is probably the easiest approachwhen additional configuration settings are used. For this installation guidewe’ll describe the installation of the application in a Tomcat server.

如前所述，UI應用程序可以部署在Tomcat服務器上，在使用其他配置設置時，這可能是最簡單的方法。對于本安裝指南，我們將描述應用程序在Tomcat服務器中的安裝。

1.? ? ?Download a recent stable version of?Apache Tomcat.

2.? ? ?Download the latest stableFlowable 6 version.

3.? ? Copy the flowable-ui.war file from the Flowable distribution?warsfolderto the Tomcat webapps folder.

4.? ? Startupthe Tomcat server by running the bin/startup.sh (Mac OS and Linux) orbin/startup.bat (Windows) script.

5.? ?Open a web browser and go to?http://localhost:8080/flowable-ui.

The Flowable UI application should now be running with anH2 in-memory database and the following login screen should be shown in yourweb browser:

1.? ? ? 下載?Apache Tomcat的最新穩定版本。

2.? ? ? 下載最新的穩定的Flowable 6版本（Flowable?6 version）。

3.? ? ? ?從Flowable 發布版的wars文件夾復制flowable-ui.war文件到Tomcat webapps文件夾。

4.? ? ? 通過運行bin/startup.sh（Mac OS和Linux）或bin/startup.bat（Windows）腳本來啟動Tomcat服務器。

5.? ? ? ?打開web瀏覽器并轉到http://localhost:8080/flowable-ui。

Flowable UI應用程序現在應該使用H2內存數據庫運行，并且web瀏覽器中應顯示以下登錄屏幕：

By default, the Flowable IDM component will create anadmin user that has privileges to all the Flowable UI apps. You can login withadmin/test and the browser should go to the Flowable landing page:

默認情況下，Flowable IDM組件將創建一個管理員用戶，該用戶對所有FlowableUI應用程序具有權限。您可以使用admin/test登錄，瀏覽器應轉到可流動的登錄頁：

Usually, you will want to change the default H2 in-memory database configuration to a MySQL or Postgres (or other persistent database) configuration. You can do this by changing the application.properties file in the?WEB-INF/classes/?directory of the application. However, it is easier to use the Spring Boot?Externalized Configuration. An example configuration can be found onGithubTo change the defaultconfiguration to MySQL the following changes are needed to the properties file:

通常，您需要將默認的H2內存數據庫配置更改為MySQL或Postgres（或其他持久數據庫）配置。你可以通過改變應用程序的WEB-INF/classes/?目錄中的application.properties文件。但是，使用Spring

Boot外部化配置（Externalized Configuration）更容易。可以在Github上找到一個示例配置，將默認配置更改為MySQL，需要對屬性文件進行以下更改：

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/flowable?characterEncoding=UTF-8

spring.datasource.username=flowable

spring.datasource.password=flowable

This configuration will expect a flowable database to bepresent in the MySQL server and the UI apps will automatically generate thenecessary database tables. For Postgres the following changes are necessary:

這種配置要求MySQL服務器中存在一個flowable數據庫，UI應用程序將自動生成必要的數據庫表。對于Postgres，需要進行以下更改：

spring.datasource.driver-class-name=org.postgresql.Driver

spring.datasource.url=jdbc:postgresql://localhost:5432/flowable

spring.datasource.username=flowable

spring.datasource.password=flowable

In addition to changing the configuration, make sure thedatabase driver is available on the classpath. Again, you could do this for theweb application by adding the driver JAR file to the WEB-INF/lib folder, butyou can also copy the JAR file to the Tomcat lib folder. For MySQL and Postgresthe database drivers can be downloaded from:

除了更改配置之外，還要確保數據庫驅動程序在classpath上可用。同樣，您可以通過將驅動程序JAR文件添加到web-INF/lib文件夾來對web應用程序執行此操作，但也可以將JAR文件復制到Tomcat lib文件夾中。對于MySQL和Postgres，可以從以下位置下載數據庫驅動程序：

MySQL:?https://dev.mysql.com/downloads/connector/j

Postgres:?https://jdbc.postgresql.org/

When running the UI as a standalone application the database driver can be added by using the?loader.pathproperty.

將UI作為獨立應用程序運行時，可以使用loader.path屬性。

java-Dloader.path=/location/to/your/driverfolder -jar flowable-ui.war
