   1 Installing Proxmox VE
   2 =====================
   3 include::attributes.txt[]
   4
   5 {pve} ships as a set of Debian packages, so you can simply install it
   6 on top of a normal Debian installation, or download the installation
   7 CD-ROM and use that to install {pve} on your hardware.
   8
   9 Installing on top of an existing Debian installation looks easy, but
  10 it presumes that you have correctly installed the base system, and you
  11 know how you want to configure and use the local storage. Network
  12 configuration is also completely up to you.
  13
  14 In general, this is not trivial, especially when you use LVM or
  15 ZFS. This is why we provide an installation CD-ROM for {pve}. That
  16 installer just ask you a few questions, then partitions the local
  17 disk(s), installs all required packages and configures the system
  18 including a basic network setup. You can get a fully functional system
  19 within a few minutes, including the following:
  20
  21 * Complete operating system (Debian Linux, 64-bit)
  22 * Partition the hard drive with ext4 (alternative ext3 or xfs) or ZFS
  23 * {pve} Kernel with LXC and KVM support
  24 * Complete toolset
  25 * Web based management interface

  34 Using the {pve} Installation CD-ROM
  35 -----------------------------------
  36
  37 This is the preferred and recommended installation method.
  38
  39 NOTE: By default, the complete server is used and all existing data is
  40 removed.
  41
  42 Please insert the installation CD-ROM, then boot from that
  43 drive. Immediately afterwards you can choose the following menu
  44 options:
  45
  46 Install Proxmox VE::
  47
  48 Start normal installation.
  49
  50 Install Proxmox VE (Debug mode)::
  51
  52 Start installation in debug mode. It opens a shell console at several
  53 installation steps, so that you can debug things if something goes
  54 wrong. Please press `CTRL-D` to exit those debug consoles and continue
  55 installation. This option is mostly for developers and not meant for
  56 general use.
  57
  58 Rescue Boot::
  59
  60 This option allows you to boot an existing installation. It searches
  61 all attached hard disks and, if it finds an existing installation,
  62 boots directly into that disk using the existing Linux kernel. This
  63 can be useful if there are problems with the boot block (grub), or the
  64 BIOS is unable to read the boot block from the disk.
  65
  66 Test Memory::
  67
  68 Runs `memtest86+`. This is useful to check if your memory is
  69 functional and error free.
  70
  71 You normally select *Install Proxmox VE* to start the installation.
  72 After that you get prompted to select the target hard disk(s). The
  73 `Options` button lets you select the target file system, which
  74 defaults to `ext4`. The installer uses LVM if you select `ext3`,
  75 `ext4` or `xfs` as file system, and offers additional option to
  76 restrict LVM space (see <<advanced_lvm_options,below>>)
  77
  78 If you have more than one disk, you can also use ZFS as file system.
  79 ZFS supports several software RAID levels, so this is specially useful
  80 if you do not have a hardware RAID controller. The `Options` button
  81 lets you select the ZFS RAID level, and you can choose disks there.
  82
  83 The next pages just ask for basic configuration options like time
  84 zone and keyboard layout. You also need to specify your email address
  85 and superuser (root) password (must have at least 5 characters).
  86
  87 The last step is the network configuration. Please note that you can
  88 use either IPv4 or IPv6 here, but not both. If you want to configure a
  89 dual stack node, you can easily do that after installation.
  90
  91 If you press `Next` now, installation starts to format disks, and
  92 copies packages to the target. Please wait until that is finished,
  93 then reboot the server.
  94
  95 Further configuration is done via the Proxmox web interface. Just
  96 point your browser to the IP address given during installation
  97 (https://youripaddress:8006).
  98
  99 NOTE: Default login is "root" (realm 'PAM') and the root password is
 100 defined during the installation process.

 104 Advanced LVM Configuration Options
 105 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 106
 107 The installer creates a Volume Group (VG) called `pve`, and additional
 108 Logical Volumes (LVs) called `root`, `data` and `swap`. The size of
 109 those volumes can be controlled with:
 110
 111 `hdsize`::
 112
 113 Defines the total HD size to be used. This way you can save free
 114 space on the HD for further partitioning (i.e. for an additional PV
 115 and VG on the same hard disk that can be used for LVM storage).
 116
 117 `swapsize`::
 118
 119 To define the size of the `swap` volume. Default is the same size as
 120 installed RAM, with 4GB minimum and `hdsize/8` as maximum.
 121
 122 `maxroot`::
 123
 124 The `root` volume size. The `root` volume stores the whole operation
 125 system.
 126
 127 `maxvz`::
 128
 129 Define the size of the `data` volume.
 130
 131 `minfree`::
 132
 133 To define the amount of free space left in LVM volume group `pve`.
 134 16GB is the default if storage available > 128GB, `hdsize/8` otherwise.
 135 +
 136 NOTE: LVM requires free space in the VG for snapshot creation (not
 137 required for lvmthin snapshots).

 140 ZFS Performance Tips
 141 ~~~~~~~~~~~~~~~~~~~~
 142
 143 ZFS uses a lot of memory, so it is best to add additional RAM if you
 144 want to use ZFS. A good calculation is 4GB plus 1GB RAM for each TB
 145 RAW disk space.
 146
 147 ZFS also provides the feature to use a fast SSD drive as write cache. The
 148 write cache is called the ZFS Intent Log (ZIL). You can add that after
 149 installation using the following command:
 150
 151  zpool add <pool-name> log </dev/path_to_fast_ssd>

 166 Install {pve} on Debian
 167 -----------------------
 168
 169 {pve} ships as a set of Debian packages, so you can simply install it
 170 on top of a normal Debian installation. After configuring the
 171 repositories, you need to run:
 172
 173 [source,bash]
 174 ----
 175 apt-get update
 176 apt-get install proxmox-ve
 177 ----
