It's great that you're diving into HAproxy configuration. Since you're using CentOS 9, there are some differences compared to CentOS 8, but I'll help you navigate through them. ### 1. **Sudo Privileges Issue** If you're facing issues with sudo privileges, it might be due to incorrect user permissions. Here's how you can check and fix it: - **Check if your user is in the `wheel` group**: This group typically has sudo privileges. You can check by running: ```bash groups ``` If you don't see `wheel` in the output, add your user to the `wheel` group: ```bash sudo usermod -aG wheel your_username ``` - **Ensure the `sudo` package is installed**: In some cases, the `sudo` package might not be installed by default. Install it using: ```bash sudo dnf install sudo ``` ### 2. **Opening 3 Different Machines** To work with multiple machines, you have a few options depending on your setup: - **Using Virtual Machines (VMs)**: - If you're running CentOS 9 on a host system, you can create multiple VMs using **VirtualBox**, **VMware**, or **KVM/QEMU**. - Once the VMs are set up, you can SSH into them from your host machine. - **Using Docker**: - You can run multiple containers with CentOS or other OS images and use them as separate machines. For example: ```bash docker run -it --name machine1 centos:9 docker run -it --name machine2 centos:9 docker run -it --name machine3 centos:9 ``` - This way, you have isolated environments for testing HAproxy configuration. ### 3. **Differences in Screen Outputs** CentOS 9 might have different package versions or slight variations in commands. If your output differs, consider the following: - **Check the exact version of the packages**: Run: ```bash sudo dnf info package_name ``` and compare it to what was used in the video. - **Compare Configuration Files**: Configuration paths or syntax may differ slightly, so always verify against CentOS 9 documentation. If you run into specific errors or need further assistance with commands, feel free to share them, and I'll guide you through the issues.
