Flowable—建模设计器等环境部署搭建

Flowable部署

• Flowable-Modeler
  为所有Flowable UI应用提供单点登录认证功能，并且为拥有IDM管理员权限的用户提供了管理用户、组与权限的功能。
• Folwable-IDM
  让具有建模权限的用户可以创建流程模型、表单、选择表与应用定义.
• Flowable-Admin
  管理应用。让具有管理员权限的用户可以查询BPMN、DMN、Form及Content引擎，并提供了许多选项用于修改流程实例、任务、作业等。管理应用通过REST API连接至引擎，并与Flowable Task应用及Flowable REST应用一同部署。
• Flowable-Task
  运行时任务应用。提供了启动流程实例、编辑任务表单、完成任务，以及查询流程实例与任务的功能
• Flowable-Rest
  提供restful风格的接口共外面调用

Flowable的下载地址

下载完毕之后是一个压缩文件：flowable-版本号.zip

然后对其进行解压：
![压缩文件解压之后](https://img-blog.csdnimg.cn/20191128165202826.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE1MDIyOTcx,size_16,color_FFFFFF,t_70)
然后打开wars文件夹：

上面我们可以看到这五个war包分别对应Flowable的五个模块。
部署的方式大概有两种：

• 部署到服务器 如：Tomcat

  1.下载解压Tomcat
  2.将上面的五个war拷贝到Tomcat目录下的webapps目录里
  
  然后启动 tomcat服务器 我们会发现在webapps文件夹下我们的应用war包被解压了

  
  如果我们要查看或者更改应用配置，比如下面我们以modeler为例：按照地址栏的路径找到对应的配置文件
  
  然后我们打开看一下：

server.port=8888
server.servlet.context-path=/flowable-modeler
management.endpoints.jmx.unique-names=true

spring.jmx.default-domain=${spring.application.name}

# Expose all actuator endpoints to the web
# They are exposed, but only authenticated users can see /info and /health abd users with access-admin can see the others
management.endpoints.web.exposure.include=*
# Full health details should only be displayed when a user is authorized
management.endpoint.health.show-details=when_authorized
# Only users with role access-admin can access full health details
management.endpoint.health.roles=access-admin
# Spring prefixes the roles with ROLE_. However, Flowable does not have that concept yet, so we need to override that with an empty string
flowable.common.app.role-prefix=

# Rest API

flowable.modeler.app.rest-enabled=true

# Configures the way user credentials are verified when doing a REST API call:
# 'any-user' : the user needs to exist and the password need to match. Any user is allowed to do the call (this is the pre 6.3.0 behavior)
# 'verify-privilege' : the user needs to exist, the password needs to match and the user needs to have the 'rest-api' privilege
# If nothing set, defaults to 'verify-privilege'
flowable.rest.app.authentication-mode=verify-privilege

# Set the tenant_id 
# For the modeler this determines under which tenant_id to store and publish models
# When not provided, empty or only contains whitespace it defaults to the user's tenant id if available 
# otherwise it uses no tenant id
#flowable.common.app.tenant-id=demo

我们可以看到上面使用的数据库默认是H2这样的内存数据库，以及一些其他的配置。如果我们需要修改配置的话，就直接修改这个文件就行了。
比如我们使用Mysql那就要使用Mysql的driver，然后配置正确的url，username和password 即可，
注意：如果配置好之后再次请启动服务器的时候报如下错误： Cannot load driver class: com.mysql.jdbc.Driver

``

那你就需要导入相关驱动器到相关的应用的lib中

• 按照java -jar flowable-modeler的形势启动

  因为这些war包也是可执行的springboot项目，所以可以直接通过上面的方式执行，然后如果要是修改应用的配置的话
  就通过-Dserver.port=8888 这样的方式，来修改配置
  ```
  

当然 flowable还支持docker的方式执行：
