2. Visual development , technological process 、 Form editing WYSIWYG , The interface style supports flexible customization , Integrable Vue,React as well as Angular.

3. Nashorn engine , Support direct use JavaScript Complete service code writing and release for use .

4. Support third parties to Restful Service mode drives and manages the process , Support data interaction between the platform and third-party services .

5. Support privatization deployment 、 Intranet deployment , Support transmission encryption , Data is more secure .

6. Provide native IOS/Android application , And support WeLink、 Nail nail is integrated with enterprise wechat .

Installation and deployment ：

Server selection ：

O2OA The development platform supports public cloud , Private cloud and hybrid cloud deployment , It also supports distributed deployment under complex network structure . This paper mainly introduces O2OA Supported deployment environments and common cluster deployment architectures .

According to the official document of the minimum deployment scheme , Tencent cloud lightweight application server is selected for this installation , Configure to CPU2 nucleus 、 Memory 4G、 System disk 60G

System selection ：

O2OA Support in Windows、AIX、MacOS、Raspberrypi（ Raspberry pie ）、ReadHat、Centos、Ubuntu、Debian、Android、Solaris、 You Qilin 、 Winning Qilin 、 Wilkoren Linux、 China, Kuwait, Fangde 、 The red flag Linux、Veket Linux、 Tongxin （UOS） operating system 、 Phoenix system 、 Installation of mainstream and domestic systems such as techno German system

This minimized deployment selects TencentOS Server Install the operating system

Lightweight application server is suitable for learning and practicing basic operation and maintenance knowledge , The operation of lightweight application server is also relatively simple , More abundant images and are a big advantage , More free zones will be put into public beta , Mirror image 、 New functions such as data disk mounting will be launched gradually .

From the perspective of market positioning, lightweight application servers are not only favored by a large number of individual developers , It has also been recognized by a large number of small enterprises and organizations ,2c4g And the machines configured above are also very suitable for private deployment and use of small organizations .
