The installation of Nexcloud can be supported by DC/OS CLI and GUI of Univese. It needs some applications such as Influx, MySQL, Redis, Kafka before the installation of Nexcloud.

※ If you have already installed these apps of Influx, MySQL, Redis, Kafka on your DC/OS Clustster, you can use existing apps. However, you have to check the your app's configuration, if specificed configuration is used. ( It is not necessary, if you use still default configuration of these apps. Please check configuration of Database Name, Password, Account, Port, VIP about these apps )

< DC/OS CLI Installation > / For more information about CLI, Go to Link (Installing the CLI)
Access to DC/OS CLI installed node

• InfluxDB

  $ dcos package install influxdb

• MySQL / MySQL-admin

  $ dcos package install mysql
  $ dcos package install mysql-admin

• Redis

  $ dcos package install redis

• Kafka

  $ dcos package install kafka

Before NexCloud installation, you have to create table and input initial data in the database (Mysql) using below sql scripts. Please login your MySql app. And execute scripts of nex_notification.sql, nex_node.sql, nex_config.sql. also please change the configuration part of scretKey, uid in nex_config.sql. this configuration is your cluster information.

1. Configuration step before Nexcloud installation
   o nex_notification.sql : this sql for create table of notification.
   o nex_node.sql : this sql for create table of DC/OS Node information.
   o nex_config.sql : this sql for input initi data of Nexcloud app configuration
   ※ these scipts works on the only mysql app. please donwn load this scripts or capy sql query form sql scpirt. and run it in the MySQL app.
   

2. Select Install Type

   -> Group Installation
   it can be supported to install all apps. ( collector, workflow, nexcloudui )
   
   -> Component Installation
         it can be supported to install each apps memually. ( collector, workflow, nexcloudui )
   ※ If you are using your existing apps (Influx, MySQL, Redis, Kafka) on your DC/OS Cluster, we recommend to install the component installation way. Because you may be change the environment configuration in your apps.  

• Execute Service

All sql scripts has to be excute in your Mysql app.

1. SQL scripts All sql scripts has to be excuted in your Mysql app.
