As a SysOps (Systems Operations) engineer, managing user accounts and permissions is a critical task. Ensuring that users are properly created, assigned to the correct groups, and have secure passwords is essential for maintaining the security and efficiency of the system. A script file (create_users.sh) will be created to automate the process of user and group creation, making it easier to manage large numbers of users and maintain a secure environment. This is a stage 1 DevOps task given at the HNG 11 INTERNSHIP PROGRAM.
- Basic knowledge of the Linux CLI (command line interface).
1. Automated User and Group Creation:
- The script reads from a file containing user and group information and automates the creation of users and their respective groups.
- Personal groups are created for each user, ensuring clear ownership and security. Group Assignment:
- Users can be assigned to multiple groups, facilitating organized and efficient permission management.
2. Secure Password Generation:
- Random passwords are generated for each user, enhancing security.
- Passwords are stored securely in a file with restricted access, ensuring that only authorized personnel can view them.
3. Logging and Documentation:
Actions performed by the script are logged to a file, providing an audit trail for accountability and troubleshooting.
1 Input File: The script takes an input file containing the list and users and groups they are to be added. it is formatted as user;groups
light; engineering,marketing,drama
idimma; drama,product
mayowa; hng-premium,design
2. Script file: You need to first make sure your script is executable by using this command chmod +x create_users.sh.
- Execute the script with root privileges to ensure it can create users and groups and manage passwords.
sudo bash create_users.sh <filename>
3. Output:
- Passwords are securely stored in
/var/secure/user_passwords.txt. - All actions are logged to
/var/log/user_management.log.
