32caab0e | 11 | {pve} is based on Debian. This is why the install disk images (ISO files) |
bdf0aff2 TL |
12 | provided by Proxmox include a complete Debian system as well as all necessary |
13 | {pve} packages. | |
14 | ||
15 | TIP: See the xref:faq-support-table[support table in the FAQ] for the | |
7f7446cf | 16 | relationship between {pve} releases and Debian releases. |

18 | The installer will guide you through the setup, allowing you to partition the |
19 | local disk(s), apply basic system configurations (for example, timezone, | |
20 | language, network) and install all required packages. This process should not | |
21 | take more than a few minutes. Installing with the provided ISO is the | |
22 | recommended method for new and existing users. | |
d91f8c1e | 23 | |
32caab0e AL |
24 | Alternatively, {pve} can be installed on top of an existing Debian system. This |
25 | option is only recommended for advanced users because detailed knowledge about | |
26 | {pve} is required. | |

38 | Using the {pve} Installer |
39 | ------------------------- | |
d91f8c1e | 40 | |
44ea3fd6 | 41 | The installer ISO image includes the following: |
115aef16 | 42 | |
e69c1847 DM |
43 | * Complete operating system (Debian Linux, 64-bit) |
44 | ||
7f7446cf | 45 | * The {pve} installer, which partitions the local disk(s) with ext4, XFS, |
520e3616 | 46 | BTRFS (technology preview), or ZFS and installs the operating system |
e69c1847 | 47 | |
9a6dc394 | 48 | * {pve} Linux kernel with KVM and LXC support |
e69c1847 | 49 | |
9a6dc394 TL |
50 | * Complete toolset for administering virtual machines, containers, the host |
51 | system, clusters and all necessary resources | |
e69c1847 | 52 | |
32caab0e | 53 | * Web-based management interface |
115aef16 | 54 | |
520e3616 CH |
55 | NOTE: All existing data on the selected drives will be removed during the |
56 | installation process. The installer does not add boot menu entries for other | |
57 | operating systems. | |
078924cd | 58 | |
44ea3fd6 TL |
59 | Please insert the xref:installation_prepare_media[prepared installation media] |
60 | (for example, USB flash drive or CD-ROM) and boot from it. | |
61 | ||
62 | TIP: Make sure that booting from the installation medium (for example, USB) is | |
3a175eaa AZ |
63 | enabled in your server's firmware settings. Secure boot needs to be disabled |
64 | when booting an installer prior to {pve} version 8.1. | |

2d99ce9b | 67 | |
520e3616 CH |
68 | After choosing the correct entry (for example, 'Boot from USB') the {pve} menu |
69 | will be displayed, and one of the following options can be selected: | |
d91f8c1e | 70 | |
0c6bf9f5 | 71 | Install {pve} (Graphical):: |
d91f8c1e | 72 | |
32caab0e | 73 | Starts the normal installation. |
d91f8c1e | 74 | |
32caab0e AL |
75 | TIP: It's possible to use the installation wizard with a keyboard only. Buttons |
76 | can be clicked by pressing the `ALT` key combined with the underlined character | |
77 | from the respective button. For example, `ALT + N` to press a `Next` button. | |
1a5554fc | 78 | |
6452603e | 79 | Install {pve} (Terminal UI):: |
0c6bf9f5 | 80 | |
520e3616 | 81 | Starts the terminal-mode installation wizard. It provides the same overall |
0c6bf9f5 CH |
82 | installation experience as the graphical installer, but has generally better |
83 | compatibility with very old and very new hardware. | |
84 | ||
8668bfdf | 85 | [thumbnail="screenshot/pve-tui-installer.png"] |
38df5426 | 86 | |
8668bfdf TL |
87 | Both modes use the same code base for the actual installation process to |
88 | benefit from more than a decade of bug fixes and ensure feature parity. | |
89 | ||
6452603e | 90 | TIP: The 'Terminal UI' option can be used in case the graphical installer does |
8668bfdf | 91 | not work correctly, due to e.g. driver issues. |
0c6bf9f5 | 92 | |
6452603e | 93 | Advanced Options: Install {pve} (Graphical, Debug Mode):: |
d91f8c1e | 94 | |
32caab0e AL |
95 | Starts the installation in debug mode. A console will be opened at several |
96 | installation steps. This helps to debug the situation if something goes wrong. | |
8dc994f7 TL |
97 | To exit a debug console, press `CTRL-D`. This option can be used to boot a live |
98 | system with all basic tools available. You can use it, for example, to | |
99 | xref:chapter_zfs[repair a degraded ZFS 'rpool'] or fix the | |
100 | xref:sysboot[bootloader] for an existing {pve} setup. | |
d91f8c1e | 101 | |
6452603e | 102 | Advanced Options: Install {pve} (Terminal UI, Debug Mode):: |
0c6bf9f5 CH |
103 | |
104 | Same as the graphical debug mode, but preparing the system to run the | |
6452603e | 105 | terminal-based installer instead. |
0c6bf9f5 | 106 | |
6452603e | 107 | Advanced Options: Install {pve} (Serial Console Debug Mode):: |
0c6bf9f5 | 108 | |
6452603e CH |
109 | Same the terminal-based debug mode, but additionally sets up the Linux kernel to |
110 | use the (first) serial port of the machine for in- and output. | |
0c6bf9f5 | 111 | |
7e5ca633 | 112 | Advanced Options: Rescue Boot:: |
d91f8c1e | 113 | |
32caab0e AL |
114 | With this option you can boot an existing installation. It searches all attached |
115 | hard disks. If it finds an existing installation, it boots directly into that | |
116 | disk using the Linux kernel from the ISO. This can be useful if there are | |
7c73a209 CH |
117 | problems with the bootloader (GRUB/`systemd-boot`) or the BIOS/UEFI is unable to |
118 | read the boot block from the disk. | |
d91f8c1e | 119 | |
0c6bf9f5 | 120 | Advanced Options: Test Memory (memtest86+):: |
d91f8c1e | 121 | |
32caab0e | 122 | Runs `memtest86+`. This is useful to check if the memory is functional and free |
b0e1acde CH |
123 | of errors. Secure Boot must be turned off in the UEFI firmware setup utility to |
124 | run this option. | |
d91f8c1e | 125 | |
520e3616 CH |
126 | You normally select *Install {pve} (Graphical)* to start the installation. |
127 | ||
1ff5e4e8 | 128 | [thumbnail="screenshot/pve-select-target-disk.png"] |
2d99ce9b | 129 | |
520e3616 CH |
130 | The first step is to read our EULA (End User License Agreement). Following this, |
131 | you can select the target hard disk(s) for the installation. | |
132 | ||
133 | CAUTION: By default, the whole server is used and all existing data is removed. | |
134 | Make sure there is no important data on the server before proceeding with the | |
135 | installation. | |
d91f8c1e | 136 | |
520e3616 CH |
137 | The `Options` button lets you select the target file system, which |
138 | defaults to `ext4`. The installer uses LVM if you select | |
139 | `ext4` or `xfs` as a file system, and offers additional options to | |
140 | restrict LVM space (see xref:advanced_lvm_options[below]). | |
32caab0e | 141 | |
520e3616 CH |
142 | {pve} can also be installed on ZFS. As ZFS offers several software RAID levels, |
143 | this is an option for systems that don't have a hardware RAID controller. The | |
144 | target disks must be selected in the `Options` dialog. More ZFS specific | |
145 | settings can be changed under xref:advanced_zfs_options[`Advanced Options`]. | |
32caab0e AL |
146 | |
147 | WARNING: ZFS on top of any hardware RAID is not supported and can result in data | |
148 | loss. | |

1ff5e4e8 | 150 | [thumbnail="screenshot/pve-select-location.png", float="left"] |
2d99ce9b | 151 | |
520e3616 CH |
152 | The next page asks for basic configuration options like your location, time |
153 | zone, and keyboard layout. The location is used to select a nearby download | |
154 | server, in order to increase the speed of updates. The installer is usually able | |
155 | to auto-detect these settings, so you only need to change them in rare | |
156 | situations when auto-detection fails, or when you want to use a keyboard layout | |
157 | not commonly used in your country. | |

1ff5e4e8 | 159 | [thumbnail="screenshot/pve-set-password.png"] |
2d99ce9b | 160 | |
520e3616 | 161 | Next the password of the superuser (`root`) and an email address needs to be |
32caab0e AL |
162 | specified. The password must consist of at least 5 characters. It's highly |
163 | recommended to use a stronger password. Some guidelines are: | |
2d99ce9b | 164 | |
520e3616 | 165 | - Use a minimum password length of at least 12 characters. |
2d99ce9b | 166 | |
32caab0e | 167 | - Include lowercase and uppercase alphabetic characters, numbers, and symbols. |
2d99ce9b | 168 | |
32caab0e AL |
169 | - Avoid character repetition, keyboard patterns, common dictionary words, |
170 | letter or number sequences, usernames, relative or pet names, romantic links | |
171 | (current or past), and biographical information (for example ID numbers, | |
172 | ancestors' names or dates). | |
2d99ce9b | 173 | |
32caab0e AL |
174 | The email address is used to send notifications to the system administrator. |
175 | For example: | |
2d99ce9b DM |
176 | |
177 | - Information about available package updates. | |
178 | ||
520e3616 | 179 | - Error messages from periodic 'cron' jobs. |
2d99ce9b | 180 | |
7df6cb98 TL |
181 | [thumbnail="screenshot/pve-setup-network.png"] |
182 | ||
520e3616 CH |
183 | All those notification mails will be sent to the specified email address. |
184 | ||
185 | The last step is the network configuration. Network interfaces that are 'UP' | |
186 | show a filled circle in front of their name in the drop down menu. Please note | |
187 | that during installation you can either specify an IPv4 or IPv6 address, but not | |
188 | both. To configure a dual stack node, add additional IP addresses after the | |
189 | installation. | |
d91f8c1e | 190 | |
1ff5e4e8 | 191 | [thumbnail="screenshot/pve-installation.png", float="left"] |
2d99ce9b | 192 | |
520e3616 CH |
193 | The next step shows a summary of the previously selected options. Please |
194 | re-check every setting and use the `Previous` button if a setting needs to be | |
195 | changed. | |
196 | ||
197 | After clicking `Install`, the installer will begin to format the disks and copy | |
198 | packages to the target disk(s). Please wait until this step has finished; then | |
199 | remove the installation medium and restart your system. | |
d91f8c1e | 200 | |
7df6cb98 TL |
201 | [thumbnail="screenshot/pve-install-summary.png"] |
202 | ||
520e3616 CH |
203 | Copying the packages usually takes several minutes, mostly depending on the |
204 | speed of the installation medium and the target disk performance. | |
205 | ||
206 | When copying and setting up the packages has finished, you can reboot the | |
207 | server. This will be done automatically after a few seconds by default. | |
208 | ||
209 | .Installation Failure | |
210 | ||
b9a97ca1 | 211 | If the installation failed, check out specific errors on the second TTY |
520e3616 CH |
212 | ('CTRL + ALT + F2') and ensure that the systems meets the |
213 | xref:install_minimal_requirements[minimum requirements]. | |
214 | ||
215 | If the installation is still not working, look at the | |
216 | xref:getting_help[how to get help chapter]. | |

220 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
221 | ||
222 | [thumbnail="screenshot/gui-login-window.png"] | |
223 | ||
224 | After a succesful installation and reboot of the system you can use the {pve} | |
225 | web interface for further configuration. | |
226 | ||
227 | . Point your browser to the IP address given during the installation and port | |
228 | 8006, for example: https://youripaddress:8006 | |
229 | ||
230 | . Log in using the `root` (realm 'PAM') username and the password chosen during | |
231 | installation. | |
232 | ||
233 | . Upload your subscription key to gain access to the Enterprise repository. | |
234 | Otherwise, you will need to set up one of the public, less tested package | |
235 | repositories to get updates for security fixes, bug fixes, and new features. | |
236 | ||
237 | . Check the IP configuration and hostname. | |

6b5fc47b | 245 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
d91f8c1e | 246 | |
32caab0e AL |
247 | The installer creates a Volume Group (VG) called `pve`, and additional Logical |
248 | Volumes (LVs) called `root`, `data`, and `swap`. To control the size of these | |
249 | volumes use: | |
d91f8c1e DM |
250 | |
251 | `hdsize`:: | |
252 | ||
32caab0e AL |
253 | Defines the total hard disk size to be used. This way you can reserve free space |
254 | on the hard disk for further partitioning (for example for an additional PV and | |
255 | VG on the same hard disk that can be used for LVM storage). | |
d91f8c1e DM |
256 | |
257 | `swapsize`:: | |
258 | ||
d3e2455a AL |
259 | Defines the size of the `swap` volume. The default is the size of the installed |
260 | memory, minimum 4 GB and maximum 8 GB. The resulting value cannot be greater | |
261 | than `hdsize/8`. | |
e8fe2b1b FG |
262 | + |
263 | NOTE: If set to `0`, no `swap` volume will be created. | |
d91f8c1e DM |
264 | |
265 | `maxroot`:: | |
266 | ||
fa281da6 TL |
267 | Defines the maximum size of the `root` volume, which stores the operation |
268 | system. The maximum limit of the `root` volume size is `hdsize/4`. | |
d91f8c1e DM |
269 | |
270 | `maxvz`:: | |
271 | ||
fa281da6 TL |
272 | Defines the maximum size of the `data` volume. The actual size of the `data` |
273 | volume is: | |
274 | + | |
275 | `datasize = hdsize - rootsize - swapsize - minfree` | |
276 | + | |
277 | Where `datasize` cannot be bigger than `maxvz`. | |
e8fe2b1b | 278 | + |
32caab0e AL |
279 | NOTE: In case of LVM thin, the `data` pool will only be created if `datasize` is |
280 | bigger than 4GB. | |
e8fe2b1b FG |
281 | + |
282 | NOTE: If set to `0`, no `data` volume will be created and the storage | |
283 | configuration will be adapted accordingly. | |
d91f8c1e DM |
284 | |
285 | `minfree`:: | |
286 | ||
32caab0e AL |
287 | Defines the amount of free space left in the LVM volume group `pve`. With more |
288 | than 128GB storage available the default is 16GB, else `hdsize/8` will be used. | |
d91f8c1e | 289 | + |
32caab0e AL |
290 | NOTE: LVM requires free space in the VG for snapshot creation (not required for |
291 | lvmthin snapshots). | |

293 | [[advanced_zfs_options]] |
294 | Advanced ZFS Configuration Options | |
295 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
32caab0e AL |
296 | The installer creates the ZFS pool `rpool`. No swap space is created but you can |
297 | reserve some unpartitioned space on the install disks for swap. You can also | |
5f318cc0 | 298 | create a swap zvol after the installation, although this can lead to problems. |
71280de0 SI |
299 | (see <<zfs_swap,ZFS swap notes>>). |
300 | ||
301 | `ashift`:: | |
302 | ||
32caab0e AL |
303 | Defines the `ashift` value for the created pool. The `ashift` needs to be set at |
304 | least to the sector-size of the underlying disks (2 to the power of `ashift` is | |
305 | the sector-size), or any disk which might be put in the pool (for example the | |
306 | replacement of a defective disk). | |
71280de0 SI |
307 | |
308 | `compress`:: | |
309 | ||
310 | Defines whether compression is enabled for `rpool`. | |
311 | ||
312 | `checksum`:: | |
313 | ||
314 | Defines which checksumming algorithm should be used for `rpool`. | |
315 | ||
316 | `copies`:: | |
317 | ||
318 | Defines the `copies` parameter for `rpool`. Check the `zfs(8)` manpage for the | |
319 | semantics, and why this does not replace redundancy on disk-level. | |
320 | ||
321 | `hdsize`:: | |
322 | ||
32caab0e | 323 | Defines the total hard disk size to be used. This is useful to save free space |
5f318cc0 | 324 | on the hard disk(s) for further partitioning (for example to create a |
32caab0e AL |
325 | swap-partition). `hdsize` is only honored for bootable disks, that is only the |
326 | first disk or mirror for RAID0, RAID1 or RAID10, and all disks in RAID-Z[123]. | |

329 | ZFS Performance Tips | |
6b5fc47b | 330 | ~~~~~~~~~~~~~~~~~~~~ |
d91f8c1e | 331 | |
32caab0e AL |
332 | ZFS works best with a lot of memory. If you intend to use ZFS make sure to have |
333 | enough RAM available for it. A good calculation is 4GB plus 1GB RAM for each TB | |
cdf58596 | 334 | RAW disk space. |
d91f8c1e | 335 | |
32caab0e AL |
336 | ZFS can use a dedicated drive as write cache, called the ZFS Intent Log (ZIL). |
337 | Use a fast drive (SSD) for it. It can be added after installation with the | |
338 | following command: | |
d91f8c1e | 339 | |

344 | Adding the `nomodeset` Kernel Parameter |
345 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
346 | ||
347 | Problems may arise on very old or very new hardware due to graphics drivers. If | |
348 | the installation hangs during the boot. In that case, you can try adding the | |
349 | `nomodeset` parameter. This prevents the Linux kernel from loading any | |
350 | graphics drivers and forces it to continue using the BIOS/UEFI-provided | |
351 | framebuffer. | |
352 | ||
353 | On the {pve} bootloader menu, navigate to 'Install {pve} (Terminal UI)' and | |
354 | press `e` to edit the entry. Using the arrow keys, navigate to the line starting | |
355 | with `linux`, move the cursor to the end of that line and add the | |
356 | parameter `nomodeset`, separated by a space from the pre-existing last | |
357 | parameter. | |
358 | ||
359 | Then press `Ctrl-X` or `F10` to boot the configuration. | |

379 | manually. | |
115aef16 | 380 | |
32caab0e | 381 | In general, this is not trivial, especially when LVM or ZFS is used. |
