15 - Python 3.7+ |
| 404 | 16 - Twisted >= 15.2.0: |
| 17 - Twisted Core | |
| 18 - Twisted Words | |
| 19 - Wokkel >= 0.7.1 (http://wokkel.ik.nu/) | |
| 20 - A XMPP server that supports the component protocol (XEP-0114), | |
| 21 and, to enable the micro-blogging feature, Namespace Delegation (XEP-0355) | |
| 22 and privileged entity (XEP-0356) are needed. | |
| 23 We recommend using Prosody with mod_privilege and mod_delegation modules (those modules | |
| 24 are maintained by us). | |
| 25 - SàT tmp (http://repos.goffi.org/sat_tmp) is currently needed for MAM and RSM handling | |
| 26 | |
| 27 For the PostgreSQL backend, the following is also required: | |
| 28 | |
| 29 - PostgreSQL >= 9.5 (including development files for psycopg2) | |
| 30 - psycopg2 | |
| 31 | |
| 32 Installation From Sources | |
| 33 ------------------------- | |
| 34 | |
| 35 To install SàT PubSub we'll work in a virtual environment. On Debian and derivatives you | |
| 36 should easily install dependencies with this:: | |
| 37 | |
| 409 | 38 sudo apt-get install postgresql python-dev mercurial virtualenv |
| 404 | 39 |
| 40 Now go in a location where you can install SàT Pubsub, for instance your home directory:: | |
| 41 | |
| 42 $ cd | |
| 43 | |

| 404 | 57 Post Installation |
| 58 ----------------- | |
| 59 | |
| 60 Once SàT Pubsub is installed, you'll need to create a PostgreSQL user, and create the | |
| 61 database:: | |
| 62 | |
| 63 % sudo -u postgres createuser -d -P $(whoami) | |
| 64 % createdb pubsub | |
| 65 % cd /tmp && wget https://repos.goffi.org/sat_pubsub/raw-file/tip/db/pubsub.sql | |
| 66 % psql pubsub < pubsub.sql | |
| 67 | |
| 68 | |
| 69 .. _prosody_configuration: | |
| 70 | |
| 71 Prosody Configuration | |
| 72 --------------------- | |
| 73 | |
| 74 SàT PubSub can work with any XMPP server (which supports components), but if you want to | |
| 75 use it as your PEP service, you need a server which supports `XEP-0355`_ and `XEP-0356`_. | |
| 76 | |
| 77 Below you'll find the instruction to use SàT PubSub as a PEP service with Prosody: | |
| 78 | |
| 79 - add these two lines at the end of your ``prosody.cfg.lua`` file, adapting them to your XMPP | |
| 80 server domain (virtual host) and selecting a password of your choice: | |
| 81 | |
| 82 .. sourcecode:: lua | |
| 83 | |
| 84 Component "sat-pubsub.<xmpp_domain>" | |
| 85 component_secret = "<password>" | |
| 86 | |
| 87 - there are extra steps to enable the micro-blogging feature with Prosody. Please follow | |
| 88 the installation and configuration instructions that are given on these pages: | |
| 89 | |
| 90 - https://modules.prosody.im/mod_delegation.html | |
| 91 - https://modules.prosody.im/mod_privilege.html | |
| 92 | |
| 93 To keep your modules up to date, we recommend to clone the full modules | |
| 94 repository and then to symlink them like that: | |
| 95 | |
| 96 .. sourcecode:: shell | |
| 97 | |
| 98 % cd /path/to/install_dir | |
| 99 % hg clone https://hg.prosody.im/prosody-modules | |
| 100 % cd /path/to/prosody_plugins | |
| 101 % ln -sf /path/to/install_dir/prosody-modules/mod_delegation ./ | |
| 102 % ln -sf /path/to/install_dir/prosody-modules/mod_privilege ./ | |
| 103 | |
| 104 Or course, you have to adapt ``/path/to/install_dir`` to the directory where you want to | |
| 105 install the modules, and ``/path/to/prosody_plugins`` to the directory where prosody | |
| 106 modules are installed (hint: check ``prosodyctl about`` to find the latter). The ``ln`` | |
| 107 commands may have to be run as root depending on your installation. | |
| 108 | |
| 109 Once your symlinks are set, to update the modules we just need to type this: | |
| 110 | |
| 111 .. sourcecode:: shell | |
| 112 | |
| 113 % cd /path/to/install_dir/prosody-modules | |
| 114 % hg pull -u | |
| 115 | |
| 116 Here is an example of how your ``prosody.cfg.lua`` should look like with | |
| 117 ``mod_delegation`` and ``mod_privilege`` activated: | |
| 118 | |
| 119 .. sourcecode:: lua | |
| 120 | |
| 121 [...] | |
| 122 modules_enabled = { | |
| 123 [...] | |
| 124 "delegation"; | |
| 125 "privilege"; | |
| 126 } | |
| 127 [...] | |
| 128 VirtualHost "<xmpp_domain>" | |
| 129 privileged_entities = { | |
| 130 ["sat-pubsub.<xmpp_domain>"] = { | |
| 131 roster = "get"; | |
| 132 message = "outgoing"; | |
| 133 presence = "roster"; | |
| 134 }, | |
| 135 } | |
| 136 delegations = { | |
| 137 ["urn:xmpp:mam:2"] = { | |
| 138 filtering = {"node"}; | |
| 139 jid = "sat-pubsub.<xmpp_domain>"; | |
| 140 }, | |
| 141 ["http://jabber.org/protocol/pubsub"] = { | |
| 142 jid = "sat-pubsub.<xmpp_domain>"; | |
| 143 }, | |
| 144 ["http://jabber.org/protocol/pubsub#owner"] = { | |
| 145 jid = "sat-pubsub.<xmpp_domain>"; | |
| 146 }, | |
| 147 ["https://salut-a-toi/protocol/schema:0"] = { | |
| 148 jid = "sat-pubsub.<xmpp_domain>"; | |
| 149 }, | |
| 150 ["http://jabber.org/protocol/disco#items:*"] = { | |
| 151 jid = "sat-pubsub.<xmpp_domain>"; | |
| 152 }, | |
| 153 ["https://salut-a-toi.org/spec/pubsub_admin:0"] = { | |
| 154 jid = "sat-pubsub.<xmpp_domain>"; | |
| 155 }, | |
| 156 } | |
| 157 | |
| 158 Component "sat-pubsub.<xmpp_domain>" | |
| 159 component_secret = "<password>" | |
| 160 modules_enabled = {"delegation", "privilege"} | |
| 161 | |
| 162 Of course, you still have to replace and adapt to your own settings. | |
| 163 | |
| 164 .. _XEP-0355: https://xmpp.org/extensions/xep-0355.html | |
| 165 .. _XEP-0356: https://xmpp.org/extensions/xep-0356.html | |
| 166 | |
| 167 Running SàT PubSub | |
| 168 ------------------ | |
| 169 | |
| 170 The minimal example for running sat_pubsub is: | |
| 171 | |
| 172 % twistd sat_pubsub | |
| 173 | |
| 174 This will start the service and run it in the background. It generates a | |
| 175 file twistd.pid that holds the PID of the service and a log file twistd.log. | |
| 176 The twistd utility has a fair number of options that might be useful, and | |
| 177 can be viewed with: | |
| 178 | |
| 179 % twistd --help | |
| 180 | |
| 181 When the service starts, it will connect to the XMPP server at the local machine using the | |
| 182 component protocol, and assumes the JID ``pubsub``. This assumes a couple of defaults | |
| 183 which can be overridden by passing parameters to the twistd plugin. You can get an | |
| 184 overview of the parameters and their defaults using: | |
| 185 | |
| 186 % twistd sat_pubsub --help | |
| 187 | |
| 188 In particular, the following parameters will be of interest: | |
| 189 | |
| 190 ``--jid`` | |
| 191 The Jabber ID the component will assume. | |
| 192 | |
| 193 ``--rport`` | |
| 194 the port number of the XMPP server to connect to | |
| 195 | |
| 196 ``--xmpp_pwd`` | |
| 197 the secret used to authenticate with the XMPP server. | |
| 198 | |
| 199 For example:: | |
| 200 | |
| 201 twistd sat_pubsub --jid=sat-pubsub.<your_xmpp_domain> --xmpp_pwd=<password> | |
| 202 | |
| 203 You can set your options in ``sat.conf`` which is the same file used as for Salut à Toi | |
| 204 ecosystem. Please check backend ``configuration`` section for details. The SàT PubSub | |
| 205 options must be in ``[pubsub]`` section. | |
