How to install on a Linux(CentOS) server

Setting up the application server

Before starting deployment make sure you have followings installed in your up to date Linux CentOS

• Docker

• Docker Composer

• Azure CLI

Or, you can use following bash commands to update the OS and install all the required applications

#!/bin/bash

echo "Update Existing OS"
sudo yum Update -y

echo "Setting Up Repository before install Docker"
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

echo "Installing Docker Engine"
sudo yum install -y docker-ce docker-ce-cli containerd.io
sudo usermod -aG docker $(whoami)
sudo systemctl enable docker
sudo systemctl start docker

echo "Install Docker Compose"
sudo yum install -y epel-release
sudo yum install -y python-pip
sudo yum install docker-compose
sudo yum upgrade python*

echo "Install Azure Cli"
sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo sh -c 'echo -e "[azure-cli]\nname=Azure CLI\nbaseurl=https://packages.microsoft.com/yumrepos/azure-cli\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/azure-cli.repo'
sudo yum install -y azure-cli 
 

Setting up the Database server

Install Microsoft SQL Server 2019 in your database server, then download & restore following bacpac files

Here is the list of databases you get after the restorations, make sure you have everything

• flowdoh-is

• flowdoh-ne

• flowdoh-workflow

• flowdoh-scheduler

• flowdoh-settings

• flowdoh-tables

• flowdoh-workspace

• flowdoh-forms

After restoring databases, execute following SQL scripts to add some default data

declare @categorypath nvarchar(max)
set @categorypath = '{hosturl}/wfengine/images/categoryicons/'
insert into [WorkflowCategory]([Name], [Icon]) values ('Other', concat(@categorypath,'Other.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Admin', concat(@categorypath,'Admin.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Banking Finance', concat(@categorypath,'BankingFinance.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Construction Development', concat(@categorypath,'ConstructionDevelopment.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Education', concat(@categorypath,'Education.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Entertainment', concat(@categorypath,'Entertainment.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Government', concat(@categorypath,'Government.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Health', concat(@categorypath,'Health.svg'))

insert into [WorkflowCategory]([Name], [Icon]) values ('Tourism', concat(@categorypath,'Tourism.svg'))
insert into [WorkflowCategory]([Name], [Icon]) values ('Travel', concat(@categorypath,'Travel.svg'))

declare @other bigint
set @other = (select top 1 [Id] from [WorkflowCategory] where [Name] = 'Other')
update [Workflow] set CategoryId = @other
