How to Set up Small Business Infrastructure

DevOps Task Solution

As a DevOps Engineer, you have been consulted to set up the infrastructure servers of a small business. Create users, and assign them to groups. Create the Company directories and assign the right access to the right groups.

SOLUTION

Setting Up the Environment and User Accounts

1. Spin up the virtual environment:

   Navigate to the project directory and use the command:

   vagrant up

2. Create a user account for the DevOps Engineer:

   Use the following command to create a user named Chika with the comment "DevOps Engineer":

   sudo adduser -c "DevOps Engineer" chika

3. Assign a password to the user Chika:

   sudo passwd chika

4. Grant sudo privileges to Chika:

   sudo usermod -aG sudo chika

5. Log into Chika's account:

   su chika

User and Group Management

1. Create users and assign comments:

   sudo useradd -c "System Administrator" andrew
   sudo useradd -c "Legal" julius
   sudo useradd -c "Human Resource Manager" chizi
   sudo useradd -c "Sales Manager" jeniffer
   sudo useradd -c "Business Strategist" adeola
   sudo useradd -c "CEO" bach
   sudo useradd -c "IT intern" gozie
   sudo useradd -c "Finance Manager" ogochukwu

2. Assign passwords to each user:

   sudo passwd andrew
   sudo passwd julius
   sudo passwd chizi
   sudo passwd jeniffer
   sudo passwd adeola
   sudo passwd bach
   sudo passwd gozie
   sudo passwd ogochukwu

3. Create groups and add users to appropriate groups:

   sudo groupadd IT_Team
   sudo usermod -aG IT_Team gozie
   sudo usermod -aG IT_Team andrew
   sudo groupadd Legal_Team
   sudo usermod -aG Legal_Team julius
   sudo groupadd Sales_Team
   sudo usermod -aG Sales_Team jeniffer
   sudo groupadd HR
   sudo usermod -aG HR chizi
   sudo groupadd Business_Team
   sudo usermod -aG Business_Team adeola
   sudo groupadd Finance_Team
   sudo usermod -aG Finance_Team ogochukwu

4. Confirm user and group creation:

   cat /etc/passwd
   cat /etc/group

Creating Directories for Kode Camp Stores Architecture

1. Create the main directory and subdirectories:

   mkdir KodeCamp_Scores
   cd KodeCamp_Scores
   mkdir Finance_Budgets
   mkdir Contract_Documents
   mkdir Business_Projections
   mkdir Business_Models
   mkdir Employee_Data
   mkdir CompanyVision_MissionStatement
   mkdir Server_Configuration.Script

Assigning Directory Permissions

1. Assign group ownership to directories:

   sudo chown -R :Finance_Team ./Finance_Budgets
   sudo chown -R :Legal_Team ./Contract_Documents
   sudo chown -R :Sales_Team ./Business_Projections
   sudo chown -R :Business_Team ./Business_Models
   sudo chown -R :HR ./Employee_Data
   sudo chown -R :HR ./CompanyVision_MissionStatement
   sudo chown -R :IT_Team ./Server_Configuration.Script

2. Verify directory permissions:

   ls -ld Finance_Budgets/

Implementing Sticky Bits

1. Apply sticky bit to each directory to prevent users from deleting each other's files:

   sudo chmod +t ./Server_Configuration.Script/
   sudo chmod +t ./CompanyVision_MissionStatement/
   sudo chmod +t ./Employee_Data/
   sudo chmod +t ./Business_Models/
   sudo chmod +t ./Business_Projections/
   sudo chmod +t ./Contract_Documents/
   sudo chmod +t ./Finance_Budgets/

2. Verify the sticky bit setting:

   ls -ld ./Server_Configuration.Script/

Following these steps, I could set up the environment, create users, assign them to groups, create necessary directories, assign permissions, and ensure directory security with sticky bits.
