| 46 Installation From Sources | |

| 48 | |
| 49 To install SàT PubSub we'll work in a virtual environment. On Debian and derivatives you | |
| 50 should easily install dependencies with this:: | |

| 86 Prosody Configuration | |
| 87 --------------------- | |
| 88 | |
| 89 SàT PubSub can work with any XMPP server (which supports components), but if you want to | |
| 90 use it as your PEP service, you need a server which supports `XEP-0355`_ and `XEP-0356`_. | |
| 91 | |
| 92 Below you'll find the instruction to use SàT PubSub as a PEP service with Prosody: | |
| 93 | |
| 94 - add these two lines at the end of your ``prosody.cfg.lua`` file, adapting them to your XMPP | |
| 95 server domain (virtual host) and selecting a password of your choice: | |
| 96 | |
| 97 .. sourcecode:: lua | |
| 98 | |
|

99 Component "pubsub.<xmpp_domain>" |
| 404 | 100 component_secret = "<password>" |
| 101 | |
| 102 - there are extra steps to enable the micro-blogging feature with Prosody. Please follow | |
| 103 the installation and configuration instructions that are given on these pages: | |
| 104 | |
| 105 - https://modules.prosody.im/mod_delegation.html | |
| 106 - https://modules.prosody.im/mod_privilege.html | |
| 107 | |
| 108 To keep your modules up to date, we recommend to clone the full modules | |
| 109 repository and then to symlink them like that: | |
| 110 | |
| 111 .. sourcecode:: shell | |
| 112 | |
| 113 % cd /path/to/install_dir | |
| 114 % hg clone https://hg.prosody.im/prosody-modules | |
| 115 % cd /path/to/prosody_plugins | |
| 116 % ln -sf /path/to/install_dir/prosody-modules/mod_delegation ./ | |
| 117 % ln -sf /path/to/install_dir/prosody-modules/mod_privilege ./ | |
| 118 | |
| 119 Or course, you have to adapt ``/path/to/install_dir`` to the directory where you want to | |
| 120 install the modules, and ``/path/to/prosody_plugins`` to the directory where prosody | |
| 121 modules are installed (hint: check ``prosodyctl about`` to find the latter). The ``ln`` | |
| 122 commands may have to be run as root depending on your installation. | |
| 123 | |
| 124 Once your symlinks are set, to update the modules we just need to type this: | |
| 125 | |
| 126 .. sourcecode:: shell | |
| 127 | |

187 % twistd sat-pubsub |
| 404 | 188 |
| 189 This will start the service and run it in the background. It generates a | |
| 190 file twistd.pid that holds the PID of the service and a log file twistd.log. | |
| 191 The twistd utility has a fair number of options that might be useful, and | |
| 192 can be viewed with: | |
| 193 | |
| 194 % twistd --help | |
| 195 | |
| 196 When the service starts, it will connect to the XMPP server at the local machine using the | |
| 197 component protocol, and assumes the JID ``pubsub``. This assumes a couple of defaults | |
| 198 which can be overridden by passing parameters to the twistd plugin. You can get an | |
| 199 overview of the parameters and their defaults using: | |

| 206 The Jabber ID the component will assume. | |

| 211 ``--xmpp_pwd`` | |
