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
26

28 Using the {pve} Installation CD-ROM
29 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
30
31 This is the preferred and recommended installation method.
32
33 NOTE: By default, the complete server is used and all existing data is
34 removed.
35
36 Please insert the installation CD-ROM, then boot from that
37 drive. Immediately afterwards you can choose the following menu
38 options:
39
40 Install Proxmox VE::
41
42 Start normal installation.
43
44 Install Proxmox VE (Debug mode)::
45
46 Start installation in debug mode. It opens a shell console at several
47 installation steps, so that you can debug things if something goes
48 wrong. Please press `CTRL-D` to exit those debug consoles and continue
49 installation. This option is mostly for developers and not meant for
50 general use.
51
52 Rescue Boot::
53
54 This option allows you to boot an existing installation. It searches
55 all attached hard disks and, if it finds an existing installation,
56 boots directly into that disk using the existing Linux kernel. This
57 can be useful if there are problems with the boot block (grub), or the
58 BIOS is unable to read the boot block from the disk.
59
60 Test Memory::
61
62 Runs `memtest86+`. This is useful to check if your memory is
63 functional and error free.
64
65 You normally select *Install Proxmox VE* to start the installation.
66 After that you get prompted to select the target hard disk(s). The
67 `Options` button lets you select the target file system, which
68 defaults to `ext4`. The installer uses LVM if you select `ext3`,
69 `ext4` or `xfs` as file system, and offers additional option to
70 restrict LVM space (see <<advanced_lvm_options,below>>)
71
72 If you have more than one disk, you can also use ZFS as file system.
73 ZFS supports several software RAID levels, so this is specially useful
74 if you do not have a hardware RAID controller. The `Options` button
75 lets you select the ZFS RAID level, and you can choose disks there.
76
77 The next pages just ask for basic configuration options like time
78 zone and keyboard layout. You also need to specify your email address
79 and superuser (root) password (must have at least 5 characters).
80
81 The last step is the network configuration. Please note that you can
82 use either IPv4 or IPv6 here, but not both. If you want to configure a
83 dual stack node, you can easily do that after installation.
84
85 If you press `Next` now, installation starts to format disks, and
86 copies packages to the target. Please wait until that is finished,
87 then reboot the server.
88
89 Further configuration is done via the Proxmox web interface. Just
90 point your browser to the IP address given during installation
91 (https://youripaddress:8006). {pve} is tested for IE9, Firefox 10
92 and higher, and Google Chrome.
93
94 NOTE: Default login is "root" (realm 'PAM') and the root password is
95 defined during the installation process.

99 Advanced LVM Configuration Options
100 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
101
102 The installer creates a Volume Group (VG) called `pve`, and additional
103 Logical Volumes (LVs) called `root`, `data` and `swap`. The size of
104 those volumes can be controlled with:
105
106 `hdsize`::
107
108 Defines the total HD size to be used. This way you can save free
109 space on the HD for further partitioning (i.e. for an additional PV
110 and VG on the same hard disk that can be used for LVM storage).
111
112 `swapsize`::
113
114 To define the size of the `swap` volume. Default is the same size as
115 installed RAM, with 4GB minimum and `hdsize/8` as maximum.
116
117 `maxroot`::
118
119 The `root` volume size. The `root` volume stores the whole operation
120 system.
121
122 `maxvz`::
123
124 Define the size of the `data` volume.
125
126 `minfree`::
127
128 To define the amount of free space left in LVM volume group `pve`.
129 16GB is the default if storage available > 128GB, `hdsize/8` otherwise.
130 +
131 NOTE: LVM requires free space in the VG for snapshot creation (not
132 required for lvmthin snapshots).

135 ZFS Performance Tips
136 ^^^^^^^^^^^^^^^^^^^^
137
138 ZFS uses a lot of memory, so it is best to add additional RAM if you
139 want to use ZFS. A good calculation is 4GB plus 1GB RAM for each TB
140 RAW disk space.
141
142 ZFS also provides the feature to use a fast SSD drive as write cache. The
143 write cache is called the ZFS Intent Log (ZIL). You can add that after
144 installation using the following command:
145
146 zpool add <pool-name> log </dev/path_to_fast_ssd>
