剧本要求

1. Create a new playbook, /home/student/playbook-review/internet.yml and add the necessary entries to start a first play named Enable internet services and specify its intended managed host, serverb.lab.example.com. Add an entry to enable privilege escalation, and one to start a task list.
2. Add the required entries to the /home/student/playbook-review/internet.yml file to define a task that installs the latest versions of firewalld, httpd, mariadb-server, php, and php-mysglnd packages.
3. Add the necessary entries to the /home/student/playbook-review/internet.yml file to define the firewall configuration tasks. They should ensure that the firewalld service is enabled and running, and that access is allowed to the httpd service.
4. Add the necessary tasks to ensure the httpd and mariadb services are enabled and running.
5. Add the necessary entries to define the final task for generating web content for testing. Use the get_url module to copy http://materials.example.com/labs/playbook-review/index.php to /var/www/htm1/ on the managed host.
6. In /home/student/playbook-review/internet.yml, define another play for the task to be performed on the control node. This play will test access to the web server that should be running on the serverb managed host. This play does not require privilege escalation, and will run on the localhost managed host.
7. Add a task that tests the web service running on serverb from the control node using the uri madule. Check for a return status code of 200.
8. Verify the syntax of the internet.yml playbook.
9. Use the ansible-playbook command to run the playbook. Read through the output generated to ensure that all tasks completed successfully.
