   • Recommended Plugins: On the “Available” tab, you can browse through the list of recommended plugins. These are the plugins commonly used and recommended by the Jenkins community. You can select the desired plugins by checking the checkbox next to their names.
   • Filter and Search: You can also use the search box or the filter options to find specific plugins based on their names or categories.
   • Plugin Dependencies: Jenkins will automatically resolve and install any dependencies required by the selected plugins.
5. Select Plugin Installation Mode: You have two options for installing plugins:
   • Install without restart: This option allows you to install the selected plugins without restarting Jenkins. It is recommended to use this option if you plan to install multiple plugins at once.
   • Download now and install after restart: This option downloads the selected plugins but installs them after Jenkins is restarted. Use this option if you prefer to install plugins one at a time or if a plugin requires Jenkins to be restarted.
6. Confirm Plugin Installation: Click the “Install” or “Download now and install after restart” button to initiate the plugin installation process. Jenkins will download and install the selected plugins.
7. Monitor Installation Progress: You will see a progress bar indicating the installation progress of the selected plugins. Depending on the number and size of the plugins, the installation process may take a few moments.
8. Restart Jenkins (if necessary): After the plugins are installed, Jenkins may prompt you to restart the server to apply the changes. If required, click the “Restart Jenkins when installation is complete and no jobs are running” checkbox and then click the “Restart Jenkins” button.
9. Verify Plugin Installation: Once Jenkins restarts, go back to the Jenkins dashboard and navigate to the desired job or configuration page that utilizes the installed plugin. Verify that the plugin is functioning as expected.

By following these steps, you can install plugins in Jenkins to extend its functionality and add features specific to your requirements.

Making an Admin User

To create an admin user, you can follow these general steps:

1. Access User Management: Log in to the system or application where you want to create the admin user. Navigate to the user management or administration section.
2. Create a New User: Look for an option to create a new user. It may be labeled as “Add User,” “Create User,” or similar. Click on that option to start the user creation process.
3. Provide User Details: Fill in the required details for the new user. This typically includes fields such as username, full name, email address, and password.
4. Assign Administrative Role: Look for a section or checkbox that allows you to assign roles or permissions to the user. Select or check the option that grants administrative privileges. The specific label or wording may vary depending on the system or application you are working with.
5. Configure Additional Settings: Depending on the system or application, there may be additional settings or options you can configure for the admin user. This could include things like access levels, security settings, or other administrative preferences. Adjust these settings as needed.
6. Save and Confirm: Once you have entered all the necessary information and configured the desired settings, save the user profile. Some systems may require you to confirm the user creation by clicking a confirmation link sent to the provided email address.
7. Test Admin Access: Log out of the system or application and then log back in using the admin user credentials. Ensure that the admin user has the expected privileges and access to the administrative features and functionalities.

It’s important to note that the steps and options may vary depending on the specific system or application you are working with. Always refer to the documentation or user guides provided by the system or application vendor for detailed instructions on creating an admin user. Additionally, consider following any security best practices, such as using strong passwords, enabling multi-factor authentication, and regularly reviewing and updating user permissions as needed.
