17 - Mercurial |
| 404 | 18 - Twisted >= 15.2.0: |
| 19 - Twisted Core | |
| 20 - Twisted Words | |
| 21 - Wokkel >= 0.7.1 (http://wokkel.ik.nu/) | |
| 22 - A XMPP server that supports the component protocol (XEP-0114), | |
| 23 and, to enable the micro-blogging feature, Namespace Delegation (XEP-0355) | |
| 24 and privileged entity (XEP-0356) are needed. | |
| 25 We recommend using Prosody with mod_privilege and mod_delegation modules (those modules | |
| 26 are maintained by us). | |
| 27 - SàT tmp (http://repos.goffi.org/sat_tmp) is currently needed for MAM and RSM handling | |
| 28 | |
| 29 For the PostgreSQL backend, the following is also required: | |
| 30 | |
| 31 - PostgreSQL >= 9.5 (including development files for psycopg2) | |
| 32 - psycopg2 | |

| 34 Installation From Sources | |
| 35 ------------------------- | |
| 36 | |
| 37 To install SàT PubSub we'll work in a virtual environment. On Debian and derivatives you | |
| 38 should easily install dependencies with this:: | |

| 42 Now go in a location where you can install SàT Pubsub, for instance your home directory:: | |
| 43 | |
| 44 $ cd | |

| 73 Prosody Configuration | |
| 74 --------------------- | |
| 75 | |
| 76 SàT PubSub can work with any XMPP server (which supports components), but if you want to | |
| 77 use it as your PEP service, you need a server which supports `XEP-0355`_ and `XEP-0356`_. | |
| 78 | |
| 79 Below you'll find the instruction to use SàT PubSub as a PEP service with Prosody: | |
| 80 | |
| 81 - add these two lines at the end of your ``prosody.cfg.lua`` file, adapting them to your XMPP | |
| 82 server domain (virtual host) and selecting a password of your choice: | |
| 83 | |
| 84 .. sourcecode:: lua | |
| 85 | |
|

|
86 Component "pubsub.<xmpp_domain>" |
| 404 | 87 component_secret = "<password>" |
| 88 | |
| 89 - there are extra steps to enable the micro-blogging feature with Prosody. Please follow | |
| 90 the installation and configuration instructions that are given on these pages: | |
| 91 | |
| 92 - https://modules.prosody.im/mod_delegation.html | |
| 93 - https://modules.prosody.im/mod_privilege.html | |
| 94 | |
| 95 To keep your modules up to date, we recommend to clone the full modules | |
| 96 repository and then to symlink them like that: | |
| 97 | |
| 98 .. sourcecode:: shell | |
| 99 | |
| 100 % cd /path/to/install_dir | |
| 101 % hg clone https://hg.prosody.im/prosody-modules | |
| 102 % cd /path/to/prosody_plugins | |
| 103 % ln -sf /path/to/install_dir/prosody-modules/mod_delegation ./ | |
| 104 % ln -sf /path/to/install_dir/prosody-modules/mod_privilege ./ | |
| 105 | |
| 106 Or course, you have to adapt ``/path/to/install_dir`` to the directory where you want to | |
| 107 install the modules, and ``/path/to/prosody_plugins`` to the directory where prosody | |
| 108 modules are installed (hint: check ``prosodyctl about`` to find the latter). The ``ln`` | |
| 109 commands may have to be run as root depending on your installation. | |
| 110 | |
| 111 Once your symlinks are set, to update the modules we just need to type this: | |
| 112 | |
| 113 .. sourcecode:: shell | |
| 114 | |

| 118 Here is an example of how your ``prosody.cfg.lua`` should look like with | |
| 119 ``mod_delegation`` and ``mod_privilege`` activated: | |
| 120 | |
| 121 .. sourcecode:: lua | |
| 122 | |
| 123 [...] | |
| 124 modules_enabled = { | |
| 125 [...] | |

| 133 roster = "get"; | |
| 134 message = "outgoing"; | |
| 135 presence = "roster"; | |
| 136 }, | |
| 137 } | |
| 138 delegations = { | |
| 139 ["urn:xmpp:mam:2"] = { | |
| 140 filtering = {"node"}; | |
| 141 jid = "sat-pubsub.<xmpp_domain>"; | |
| 142 }, | |
| 143 ["http://jabber.org/protocol/pubsub"] = { | |
| 144 jid = "sat-pubsub.<xmpp_domain>"; | |
| 145 }, | |
| 146 ["http://jabber.org/protocol/pubsub#owner"] = { | |
| 147 jid = "sat-pubsub.<xmpp_domain>"; | |
| 148 }, | |
| 149 ["https://salut-a-toi/protocol/schema:0"] = { | |
| 150 jid = "sat-pubsub.<xmpp_domain>"; | |
| 151 }, | |
| 152 ["http://jabber.org/protocol/disco#items:*"] = { | |
| 153 jid = "sat-pubsub.<xmpp_domain>"; | |
| 154 }, | |
| 155 ["https://salut-a-toi.org/spec/pubsub_admin:0"] = { | |
| 156 jid = "sat-pubsub.<xmpp_domain>"; | |
| 157 }, | |
| 158 } | |
| 159 | |
| 160 Component "sat-pubsub.<xmpp_domain>" | |
| 161 component_secret = "<password>" | |
| 162 modules_enabled = {"delegation", "privilege"} | |
| 163 | |
| 164 Of course, you still have to replace and adapt to your own settings. | |

| 169 Running SàT PubSub | |

|
174 % twistd sat-pubsub |
| 404 | 175 |
| 176 This will start the service and run it in the background. It generates a | |
| 177 file twistd.pid that holds the PID of the service and a log file twistd.log. | |
| 178 The twistd utility has a fair number of options that might be useful, and | |
| 179 can be viewed with: | |
| 180 | |
| 181 % twistd --help | |
| 182 | |
| 183 When the service starts, it will connect to the XMPP server at the local machine using the | |
| 184 component protocol, and assumes the JID ``pubsub``. This assumes a couple of defaults | |
| 185 which can be overridden by passing parameters to the twistd plugin. You can get an | |
| 186 overview of the parameters and their defaults using: | |

188 % twistd sat-pubsub --help |
| 404 | 189 |
| 190 In particular, the following parameters will be of interest: | |
| 191 | |
| 192 ``--jid`` | |
| 193 The Jabber ID the component will assume. | |
| 194 | |
| 195 ``--rport`` | |
| 196 the port number of the XMPP server to connect to | |
| 197 | |
| 198 ``--xmpp_pwd`` | |
| 199 the secret used to authenticate with the XMPP server. | |
| 200 | |

| 404 | 204 |
| 205 You can set your options in ``sat.conf`` which is the same file used as for Salut à Toi | |
| 206 ecosystem. Please check backend ``configuration`` section for details. The SàT PubSub | |
| 207 options must be in ``[pubsub]`` section. | |
