1 | Installation |
2 | ============ | |
3 | ||
8eb27e2f TL |
4 | {pmg} is based on Debian. This is why the install disk images (ISO files) |
5 | provided by Proxmox include a complete Debian system as well as all necessary | |
6 | {pmg} packages. | |
03c03402 | 7 | |
8eb27e2f TL |
8 | TIP: See the xref:faq-support-table[support table in the FAQ] for the |
9 | relationship between {pmg} releases and Debian releases. | |
03c03402 | 10 | |
c78dc3bb | 11 | The installer will guide you through the setup, allowing you to partition the local |
8eb27e2f TL |
12 | disk(s), apply basic system configurations (for example, timezone, language, |
13 | network) and install all required packages. This process should not take more | |
14 | than a few minutes. Installing with the provided ISO is the recommended method | |
15 | for new and existing users. | |
16 | ||
17 | Alternatively, {pmg} can be installed on top of an existing Debian system. This | |
18 | option is only recommended for advanced users because detailed knowledge about | |
19 | {pmg} is required. | |

24 | Using the {pmg} Installation CD-ROM |
25 | ----------------------------------- | |
26 | ||
dfcaa012 | 27 | The installer ISO image includes the following: |
03c03402 DM |
28 | |
29 | * Complete operating system (Debian Linux, 64-bit) | |
30 | ||
b2d388d4 | 31 | * The {pmg} installer, which partitions the hard drive(s) with ext4, |
8eb27e2f | 32 | XFS or ZFS and installs the operating system |
03c03402 DM |
33 | |
34 | * Linux kernel | |
35 | ||
36 | * Postfix MTA, ClamAV, Spamassassin and the {pmg} toolset | |
37 | ||
582a64ad | 38 | * Web-based management interface for using the toolset |
03c03402 | 39 | |
b2d388d4 | 40 | |
dfcaa012 AL |
41 | Please insert the xref:installation_prepare_media[prepared installation media] |
42 | (for example, USB flash drive or CD-ROM) and boot from it. | |
43 | ||
44 | TIP: Make sure that booting from the installation medium (for example, USB) is | |
45 | enabled in your servers firmware settings. | |
46 | ||
bf99325b DW |
47 | After choosing the correct entry (for example, Boot from USB) the {pmg} menu |
48 | will be displayed, and one of the following options can be selected: | |
03c03402 DM |
49 | |
50 | image::images/installer/pmg-grub-menu.png[] | |
51 | ||
52 | Install {pmg}:: | |
53 | ||
54 | Start normal installation. | |
55 | ||
56 | Install {pmg} (Debug mode):: | |
57 | ||
bf99325b DW |
58 | Start installation in debug mode. This opens a shell console at various stages |
59 | throughout the installation, so that you can debug issues, if something goes | |
60 | wrong. You can press `CTRL-D` to exit the debug console and continue the | |
61 | installation. This option is mostly for developers and not meant for general | |
62 | use. | |
03c03402 DM |
63 | |
64 | Rescue Boot:: | |
65 | ||
66 | This option allows you to boot an existing installation. It searches | |
67 | all attached hard disks and, if it finds an existing installation, | |
68 | boots directly into that disk using the existing Linux kernel. This | |
69 | can be useful if there are problems with the boot block (grub), or the | |
70 | BIOS is unable to read the boot block from the disk. | |
71 | ||
72 | Test Memory:: | |
73 | ||
74 | Runs `memtest86+`. This is useful to check if your memory is | |
75 | functional and error free. | |
76 | ||
dc69da07 | 77 | You normally select *Install {pmg}* to start the installation. |
03c03402 | 78 | |

03c03402 | 80 | |
bf99325b DW |
81 | The first step is to read our EULA (End User License Agreement). Following |
82 | this, you can select the target hard disk(s) for the installation. | |
03c03402 | 83 | |
582a64ad OB |
84 | CAUTION: By default, the whole server is used and all existing data is removed. |
85 | Make sure there is no important data on the server before proceeding with the | |
86 | installation. | |
03c03402 | 87 | |
03c03402 | 88 | The `Options` button lets you select the target file system, which |
12908dd2 | 89 | defaults to `ext4`. The installer uses LVM if you select |
bf99325b | 90 | `ext4` or `xfs` as a file system, and offers additional options to |
03c03402 DM |
91 | restrict LVM space (see <<advanced_lvm_options,below>>) |
92 | ||
bf99325b DW |
93 | If you have more than one disk, you can also use ZFS as a file system. |
94 | ZFS supports several software RAID levels, which is particularly useful | |
03c03402 | 95 | if you do not have a hardware RAID controller. The `Options` button |
bf99325b | 96 | lets you choose the ZFS RAID level and select which disks will be used. |
03c03402 | 97 | |

98 | image::images/installer/pmg-select-location.png[] |
99 | ||
582a64ad | 100 | The next page asks for basic configuration options like your |
bf99325b DW |
101 | location, timezone, and keyboard layout. The location is used to |
102 | select a nearby download server, in order to increase the speed of updates. | |
103 | The installer is usually able to auto-detect these settings, so you only need to | |
104 | change them in rare situations when auto-detection fails, or when you want to | |
582a64ad | 105 | use a keyboard layout not commonly used in your country. |
dc69da07 DM |
106 | |
107 | image::images/installer/pmg-set-password.png[] | |
108 | ||
109 | You then need to specify an email address and the superuser (root) | |
110 | password. The password must have at least 5 characters, but we highly | |
111 | recommend to use stronger passwords - here are some guidelines: | |
112 | ||
113 | - Use a minimum password length of 12 to 14 characters. | |
114 | ||
115 | - Include lowercase and uppercase alphabetic characters, numbers and symbols. | |
116 | ||
60522152 TL |
117 | - Avoid character repetition, keyboard patterns, dictionary words, letter or |
118 | number sequences, usernames, relative or pet names, romantic links (current | |
119 | or past) and biographical information (e.g., ID numbers, ancestors' names or | |
120 | dates). | |
dc69da07 | 121 | |
aecce55c TL |
122 | It is sometimes necessary to send notification to the system administrator, for |
123 | example: | |
dc69da07 DM |
124 | |
125 | - Information about available package updates. | |
126 | ||
bf99325b | 127 | - Error messages from periodic cron jobs. |
dc69da07 | 128 | |
aecce55c | 129 | All those notification mails will be sent to the specified email address. |
dc69da07 DM |
130 | |
131 | image::images/installer/pmg-setup-network.png[] | |
03c03402 | 132 | |
aecce55c TL |
133 | The next step is the network configuration. Please note that you can use either |
134 | IPv4 or IPv6 here, but not both. If you want to configure a dual stack node, | |
bf99325b | 135 | you can easily do that after the installation. |

137 | image::images/installer/pmg-summary.png[] |
138 | ||
aecce55c TL |
139 | When you press `Next`, you will see an overview of your entered configuration. |
140 | Please re-check every setting, you can still use the `Previous` button to go | |
141 | back and edit any settings. | |
f6249b79 | 142 | |
bf99325b DW |
143 | After clicking `Install`, the installer will begin to format and copy packages |
144 | to the target disk(s). | |
dc69da07 DM |
145 | |
146 | image::images/installer/pmg-installation.png[] | |
147 | ||
bf99325b DW |
148 | Copying the packages usually takes several minutes. When this is |
149 | finished, you can reboot the server. | |
03c03402 | 150 | |
bf99325b | 151 | Further configuration is done via the {pmg} web interface: |

152 | |
153 | [thumbnail="pmg-gui-login-window.png"] | |
03c03402 | 154 | |

f03ead41 | 156 | (https://youripaddress:8006). |
b5b01ac3 | 157 | |
bf99325b | 158 | . Log in and upload your subscription key. |

bf99325b | 160 | NOTE: The default login is "root", and the password is the one chosen during the |
aecce55c | 161 | installation. |
03c03402 | 162 | |
b2d388d4 DM |
163 | . Check the IP configuration and hostname. |
164 | ||
bf99325b | 165 | . Check the timezone. |
b2d388d4 DM |
166 | |
167 | . Check your xref:firewall_settings[Firewall settings]. | |
168 | ||
bf99325b | 169 | . Configure {pmg} to forward the incoming SMTP traffic to your mail |
b2d388d4 | 170 | server ('Configuration/Mail Proxy/Default Relay') - 'Default |
09e283f2 | 171 | Relay' is your email server. |
b2d388d4 | 172 | |
09e283f2 | 173 | . Configure your email server to send all outgoing messages through |
303ee757 | 174 | your {pmg} ('Smart Host', port 26 by default). |
b2d388d4 DM |

177 | xref:chapter_deployment[Planning for Deployment]. | |
178 | ||
bf99325b DW |
179 | After the installation, you have to route all your incoming and |
180 | outgoing email traffic to {pmg}. For incoming traffic, you | |
b2d388d4 | 181 | have to configure your firewall and/or DNS settings. For outgoing |
09e283f2 | 182 | traffic you need to change the existing email server configuration. |

185 | [[advanced_lvm_options]] | |
186 | Advanced LVM Configuration Options | |
187 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
188 | ||
189 | The installer creates a Volume Group (VG) called `pmg`, and additional | |
190 | Logical Volumes (LVs) called `root` and `swap`. The size of | |
191 | those volumes can be controlled with: | |
192 | ||
193 | `hdsize`:: | |
194 | ||
582a64ad OB |
195 | Defines the total disk size to be used. This way you can save free |
196 | space on the disk for further partitioning (i.e. for an additional PV | |
197 | and VG on the same disk that can be used for LVM storage). | |
03c03402 DM |
198 | |
199 | `swapsize`:: | |
200 | ||
201 | Defines the size of the `swap` volume. The default is the size of the | |
bf99325b DW |
202 | installed memory. The minimum is 4 GB and the maximum is 8 GB. The resulting |
203 | value cannot be greater than `hdsize/8`. | |
03c03402 | 204 | |
03c03402 DM |
205 | `minfree`:: |
206 | ||
bf99325b DW |
207 | Defines the amount of free space that should be left in the LVM volume group |
208 | `pmg`. With more than 128GB storage available, the default is 16GB, otherwise | |
209 | `hdsize/8` will be used. | |
03c03402 DM |
210 | + |
211 | NOTE: LVM requires free space in the VG for snapshot creation (not | |
212 | required for lvmthin snapshots). | |
213 | ||
214 | ||
215 | ZFS Performance Tips | |
216 | ~~~~~~~~~~~~~~~~~~~~ | |
217 | ||
218 | ZFS uses a lot of memory, so it is best to add additional RAM if you | |
219 | want to use ZFS. A good calculation is 4GB plus 1GB RAM for each TB | |
220 | RAW disk space. | |
221 | ||
bf99325b | 222 | ZFS also provides the ability to use a fast SSD drive as write cache. The |
03c03402 | 223 | write cache is called the ZFS Intent Log (ZIL). You can add that after |
582a64ad | 224 | the installation using the following command: |
03c03402 DM |
225 | |
226 | zpool add <pool-name> log </dev/path_to_fast_ssd> | |

230 | Install {pmg} on Debian |
231 | ----------------------- | |
232 | ||
233 | {pmg} ships as a set of Debian packages, so you can install it | |
234 | on top of a normal Debian installation. After configuring the | |
bf99325b | 235 | xref:pmg_package_repositories[package repositories], you need to run: |
03c03402 DM |
236 | |
237 | [source,bash] | |
238 | ---- | |
3e2d2270 TL |
239 | apt update |
240 | apt install proxmox-mailgateway | |
03c03402 DM |
241 | ---- |
242 | ||
bf99325b | 243 | Installing on top of an existing Debian installation seems easy, but |
582a64ad | 244 | it assumes that you have correctly installed the base system, and you |
03c03402 DM |
245 | know how you want to configure and use the local storage. Network |
246 | configuration is also completely up to you. | |
247 | ||
248 | NOTE: In general, this is not trivial, especially when you use LVM or | |
249 | ZFS. | |

bf99325b | 253 | Install {pmg} as a Linux Container Appliance |
3fc72cc0 | 254 | -------------------------------------------- |
c13d3d4f | 255 | |
bf99325b | 256 | {pmg} can also run inside a Debian-based LXC |
c13d3d4f | 257 | instance. In order to keep the set of installed software, and thus the |
582a64ad | 258 | necessary updates minimal, you can use the `proxmox-mailgateway-container` |
bf99325b | 259 | meta-package. This does not depend on any Linux kernel, firmware, or components |
c13d3d4f | 260 | used for booting from bare-metal, like grub2. |
17a13972 | 261 | |
bf99325b DW |
262 | A ready-to-use appliance template is available through the `mail` section of the |
263 | https://www.proxmox.com/proxmox-ve[Proxmox VE] appliance manager, so if you | |
264 | already use Proxmox VE, you can set up a {pmg} instance in minutes. | |
17a13972 | 265 | |
bf99325b DW |
266 | NOTE: It's recommended to use a static network configuration. If DHCP must be |
267 | used, ensure that the container always leases the same IP, for example, by | |
268 | reserving one with the container's network MAC address. | |
5991f9eb | 269 | |
bf99325b | 270 | Additionally, you can install this on top of a container-based Debian |
3e2d2270 | 271 | installation. After configuring the |
bf99325b | 272 | xref:pmg_package_repositories[package repositories], you need to run: |

bf99325b | 285 | https://en.wikipedia.org/wiki/Advanced_Packaging_Tool[APT] as a package |
e3eaa56a DM |
286 | management tool. The list of repositories is defined in |

310 | ||
311 | ||
312 | {pmg} Enterprise Repository | |
313 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
314 | ||
315 | This is the default, stable and recommended repository, available for | |
316 | all {pmg} subscription users. It contains the most stable packages, | |
317 | and is suitable for production use. The `pmg-enterprise` repository is | |
318 | enabled by default: | |

323 | ---- |
324 | ||
325 | As soon as updates are available, the `root@pam` user is notified via | |
bf99325b | 326 | email about the newly available packages. From the GUI, the change-log of |
e3eaa56a | 327 | each package can be viewed (if available), showing all details of the |
bf99325b | 328 | update. Thus, you will never miss important security fixes. |
e3eaa56a | 329 | |
bf99325b DW |
330 | Please note that you need a valid subscription key to access this |
331 | repository. We offer different support levels, which you can find further | |
332 | details about at {pricing-url}. | |
e3eaa56a DM |
333 | |
334 | NOTE: You can disable this repository by commenting out the above line | |
bf99325b | 335 | using a `#` (at the start of the line). This prevents error messages, |
e3eaa56a | 336 | if you do not have a subscription key. Please configure the |
bf99325b | 337 | `pmg-no-subscription` repository in this case. |
e3eaa56a DM |
338 | |
339 | ||
340 | {pmg} No-Subscription Repository | |
341 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
342 | ||
343 | As the name suggests, you do not need a subscription key to access | |
344 | this repository. It can be used for testing and non-production | |
bf99325b | 345 | use. It's not recommended to use this on production servers, as these |
e3eaa56a DM |
346 | packages are not always heavily tested and validated. |
