This script installs and configures basic tools for running a Proxmox Server.
Following settings are made:
- Disable `pve-enterprise` repo
- Add `pve-no-subscription` repo
- Upgrade system to latest version
- Install basic tools: `sudo vim ifupdown2 net-tools dnsutils ethtool git curl unzip screen iftop lshw smartmontools nvme-cli lsscsi sysstat zfs-auto-snapshot htop mc rpl`
- Configure snapshot retention for `zfs-auto-snapshot` interactively
- `zfs_arc_[min|max]` will be calculated by size sum of all zpools in 512 MB steps
- Configure backup of `/etc` folder to new zfs dataset on `rpool/pveconf`
- Configure `vm.swappiness` interactively
- Install checkmk Agent with optional encryption and registration
- Added Support for Proxmox VE 7.0
- Added Proxmox SDN features
- Install and configure zfs-auto-snapshot
- Switch pve-enterprise/pve-no-subscription/pvetest repo
- Switch ceph repo between quincy/reef and enterprise/no-subscription/test or remove it
- Disable "No subscription message" in webinterface in no-subscription mode
- Add pve-enterprise subscription key
- Update system to the latest version
- Install common tools
- Install Proxmox SDN Extensions
- Configure automatic backup of /etc Folder
- Configure locales
- SSH server hardening
- Install checkzfs
- Install bashclub-zsync
- Create zfspool storage for swap disks if not exists
- Adjust default volblocksize for Proxmox zfspool storage
- Configure proxmox mail delivery with postfix
- Daily check (and download) for new stable virtio-win iso and prune old (unused) versions
# Usage
Just download and execute the script, all settings are made interactively.
