Flowable UI應(yīng)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.

如前所述捻艳，UI應(yīng)用程序可以部署在Tomcat服務(wù)器上，在使用其他配置設(shè)置時(shí)庆猫，這可能是最簡單的方法认轨。對(duì)于本安裝指南，我們將描述應(yīng)用程序在Tomcat服務(wù)器中的安裝月培。

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(wěn)定版本嘁字。

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

3.? ? ? ?從Flowable 發(fā)布版的wars文件夾復(fù)制flowable-ui.war文件到Tomcat webapps文件夾杉畜。

4.? ? ? 通過運(yùn)行bin/startup.sh（Mac OS和Linux）或bin/startup.bat（Windows）腳本來啟動(dòng)Tomcat服務(wù)器纪蜒。

5.? ? ? ?打開web瀏覽器并轉(zhuǎn)到http://localhost:8080/flowable-ui。

Flowable UI應(yīng)用程序現(xiàn)在應(yīng)該使用H2內(nèi)存數(shù)據(jù)庫運(yùn)行此叠，并且web瀏覽器中應(yīng)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(rèn)情況下纯续，F(xiàn)lowable IDM組件將創(chuàng)建一個(gè)管理員用戶，該用戶對(duì)所有FlowableUI應(yīng)用程序具有權(quán)限灭袁。您可以使用admin/test登錄猬错，瀏覽器應(yīng)轉(zhuǎn)到可流動(dòng)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(rèn)的H2內(nèi)存數(shù)據(jù)庫配置更改為MySQL或Postgres（或其他持久數(shù)據(jù)庫）配置茸歧。你可以通過改變應(yīng)用程序的WEB-INF/classes/?目錄中的application.properties文件倦炒。但是，使用Spring

Boot外部化配置（Externalized Configuration）更容易软瞎》昊剑可以在Github上找到一個(gè)示例配置，將默認(rèn)配置更改為MySQL涤浇，需要對(duì)屬性文件進(jìn)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(wù)器中存在一個(gè)flowable數(shù)據(jù)庫鳖藕，UI應(yīng)用程序?qū)⒆詣?dòng)生成必要的數(shù)據(jù)庫表。對(duì)于Postgres芙代，需要進(jìn)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:

除了更改配置之外吊奢，還要確保數(shù)據(jù)庫驅(qū)動(dòng)程序在classpath上可用。同樣纹烹，您可以通過將驅(qū)動(dòng)程序JAR文件添加到web-INF/lib文件夾來對(duì)web應(yīng)用程序執(zhí)行此操作页滚，但也可以將JAR文件復(fù)制到Tomcat lib文件夾中。對(duì)于MySQL和Postgres铺呵，可以從以下位置下載數(shù)據(jù)庫驅(qū)動(dòng)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(dú)立應(yīng)用程序運(yùn)行時(shí)裹驰，可以使用loader.path屬性。

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