20 | GNU MediaGoblin is fairly new and so at the time of writing, there |
21 | aren't easy package-manager-friendly methods to install MediaGoblin. | |
22 | However, doing a basic install isn't too complex in and of itself. | |

e260065a CAW |
24 | There's an almost infinite way to deploy things... for now, we'll keep |
25 | it simple with some assumptions and use a setup that combines | |
26 | mediagoblin + virtualenv + fastcgi + nginx on a .deb or .rpm based | |
27 | GNU/Linux distro. | |

35 | There are also many ways to install servers... for the sake of |
36 | simplicity, our instructions below describe installing with nginx. | |

4e893b6e | 43 | Dependencies |
44 | ~~~~~~~~~~~~ | |
e260065a | 45 | |
4e893b6e | 46 | MediaGoblin has the following core dependencies: |
e260065a | 47 | |
4e893b6e | 48 | - Python 2.6 or 2.7 |
49 | - `python-lxml <http://lxml.de/>`_ | |
50 | - `git <http://git-scm.com/>`_ | |
775ec9e8 | 51 | - `SQLite <http://www.sqlite.org/>`_/`PostgreSQL <http://www.postgresql.org/>`_ |
4e893b6e | 52 | - `Python Imaging Library <http://www.pythonware.com/products/pil/>`_ (PIL) |
53 | - `virtualenv <http://www.virtualenv.org/>`_ | |
e260065a | 54 | |
4e893b6e | 55 | On a DEB-based system (e.g Debian, gNewSense, Trisquel, Ubuntu, and |
7798f911 | 56 | derivatives) issue the following command:: |
e260065a | 57 | |
775ec9e8 | 58 | sudo apt-get install git-core python python-dev python-lxml \ |
076bf0cf | 59 | python-imaging python-virtualenv |
e260065a | 60 | |
4e893b6e | 61 | On a RPM-based system (e.g. Fedora, RedHat, and derivatives) issue the |
7798f911 | 62 | following command:: |
4e893b6e | 63 | |
775ec9e8 | 64 | yum install python-paste-deploy python-paste-script \ |
076bf0cf WKG |
65 | git-core python python-devel python-lxml python-imaging \ |
66 | python-virtualenv | |

68 | Configure PostgreSQL |
69 | ~~~~~~~~~~~~~~~~~~~~ | |
70 | ||
71 | .. note:: | |
72 | ||
7798f911 WKG |
73 | MediaGoblin currently supports PostgreSQL and SQLite. The default is a |
74 | local SQLite database. This will "just work" for small deployments. | |
775ec9e8 | 75 | |
7798f911 WKG |
76 | For medium to large deployments we recommend PostgreSQL. |
77 | ||
78 | If you don't want/need postgres, skip this section. | |
79 | ||
80 | These are the packages needed for Debian Wheezy (testing):: | |
775ec9e8 | 81 | |
21a84362 | 82 | sudo apt-get install postgresql postgresql-client python-psycopg2 |
775ec9e8 JW |
83 | |
84 | The installation process will create a new *system* user named ``postgres``, | |
85 | it will have privilegies sufficient to manage the database. We will create a | |
86 | new database user with restricted privilegies and a new database owned by our | |
87 | restricted database user for our MediaGoblin instance. | |
88 | ||
89 | In this example, the database user will be ``mediagoblin`` and the database | |
90 | name will be ``mediagoblin`` too. | |
91 | ||
7798f911 | 92 | To create our new user, run:: |
775ec9e8 JW |
93 | |
94 | sudo -u postgres createuser mediagoblin | |
95 | ||
7798f911 | 96 | then answer NO to *all* the questions:: |
775ec9e8 JW |
97 | |
98 | Shall the new role be a superuser? (y/n) n | |
99 | Shall the new role be allowed to create databases? (y/n) n | |
100 | Shall the new role be allowed to create more new roles? (y/n) n | |
101 | ||
7798f911 | 102 | then create the database all our MediaGoblin data should be stored in:: |
775ec9e8 JW |
103 | |
104 | sudo -u postgres createdb -E UNICODE -O mediagoblin mediagoblin | |
105 | ||
106 | where the first ``mediagoblin`` is the database owner and the second | |
107 | ``mediagoblin`` is the database name. | |
108 | ||
109 | .. caution:: Where is the password? | |
110 | ||
111 | These steps enable you to authenticate to the database in a password-less | |
112 | manner via local UNIX authentication provided you run the MediaGoblin | |
113 | application as a user with the same name as the user you created in | |
114 | PostgreSQL. | |
115 | ||
116 | More on this in :ref:`Drop Privileges for MediaGoblin <drop-privileges-for-mediagoblin>`. | |

120 | ||
4e893b6e | 121 | Drop Privileges for MediaGoblin |
122 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
17c71230 | 123 | |
4e893b6e | 124 | As MediaGoblin does not require special permissions or elevated |
125 | access, you should run MediaGoblin under an existing non-root user or | |
126 | preferably create a dedicated user for the purpose of running | |
127 | MediaGoblin. Consult your distribution's documentation on how to | |
128 | create "system account" or dedicated service user. Ensure that it is | |
129 | not possible to log in to your system with as this user. | |
17c71230 | 130 | |
4e893b6e | 131 | You should create a working directory for MediaGoblin. This document |
076bf0cf WKG |
132 | assumes your local git repository will be located at |
133 | ``/srv/mediagoblin.example.org/mediagoblin/`` for this documentation. | |
134 | Substitute your prefer ed local deployment path as needed. | |
17c71230 | 135 | |
4e893b6e | 136 | This document assumes that all operations are performed as this |
7798f911 | 137 | user. To drop privileges to this user, run the following command:: |
17c71230 | 138 | |
076bf0cf | 139 | su - [mediagoblin] |
17c71230 | 140 | |
076bf0cf | 141 | Where, "``[mediagoblin]``" is the username of the system user that will |
4e893b6e | 142 | run MediaGoblin. |
143 | ||
e260065a | 144 | Install MediaGoblin and Virtualenv |
4e893b6e | 145 | ---------------------------------- |
e260065a | 146 | |
076bf0cf WKG |
147 | .. note:: |
148 | ||
7798f911 | 149 | MediaGoblin is still developing rapidly. As a result |
076bf0cf WKG |
150 | the following instructions recommend installing from the ``master`` |
151 | branch of the git repository. Eventually production deployments will | |
152 | want to transition to running from more consistent releases. | |
e260065a | 153 | |
4e893b6e | 154 | Issue the following commands, to create and change the working |
076bf0cf | 155 | directory. Modify these commands to reflect your own environment:: |
17c71230 | 156 | |
076bf0cf WKG |
157 | mkdir -p /srv/mediagoblin.example.org/ |
158 | cd /srv/mediagoblin.example.org/ | |
17c71230 | 159 | |
076bf0cf | 160 | Clone the MediaGoblin repository:: |
e260065a | 161 | |
076bf0cf | 162 | git clone git://gitorious.org/mediagoblin/mediagoblin.git |
e260065a | 163 | |
7798f911 | 164 | And set up the in-package virtualenv:: |
e260065a | 165 | |
076bf0cf | 166 | cd mediagoblin |
95ff15d6 | 167 | (virtualenv --system-site-packages . || virtualenv .) && ./bin/python setup.py develop |
e260065a | 168 | |
4e893b6e | 169 | .. note:: |
e260065a | 170 | |
4e893b6e | 171 | If you have problems here, consider trying to install virtualenv |
172 | with the ``--distribute`` or ``--no-site-packages`` options. If | |
c356dc16 | 173 | your system's default Python is in the 3.x series you may need to |
4e893b6e | 174 | run ``virtualenv`` with the ``--python=python2.7`` or |
175 | ``--python=python2.6`` options. | |
e260065a | 176 | |
4e893b6e | 177 | The above provides an in-package install of ``virtualenv``. While this |
178 | is counter to the conventional ``virtualenv`` configuration, it is | |
179 | more reliable and considerably easier to configure and illustrate. If | |
180 | you're familiar with Python packaging you may consider deploying with | |
c356dc16 | 181 | your preferred method. |
e260065a | 182 | |
076bf0cf WKG |
183 | Assuming you are going to deploy with FastCGI, you should also install |
184 | flup:: | |
99192f24 | 185 | |
076bf0cf | 186 | ./bin/easy_install flup |
99192f24 | 187 | |
4e893b6e | 188 | This concludes the initial configuration of the development |
8d9aa03f | 189 | environment. In the future, when you update your |
076bf0cf | 190 | codebase, you should also run:: |
e260065a | 191 | |
084a6190 | 192 | ./bin/python setup.py develop --upgrade && ./bin/gmg dbupdate |
e260065a | 193 | |
9d5cd0b9 CAW |
194 | Note: If you are running an active site, depending on your server |
195 | configuration, you may need to stop it first or the dbupdate command | |
196 | may hang (and it's certainly a good idea to restart it after the | |
197 | update) | |

775ec9e8 JW |
203 | Configure MediaGoblin to use the PostgreSQL database |
204 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
205 | ||
7798f911 WKG |
206 | If you are using postgres, edit the ``[mediagoblin]`` section in your |
207 | ``mediagoblin_local.ini`` and put in:: | |
775ec9e8 JW |
208 | |
209 | sql_engine = postgresql:///mediagoblin | |
210 | ||
211 | if you are running the MediaGoblin application as the same 'user' as the | |
212 | database owner. | |
213 | ||
7798f911 | 214 | |
775ec9e8 JW |
215 | Update database data structures |
216 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
217 | ||
7798f911 | 218 | Before you start using the database, you need to run:: |
775ec9e8 JW |
219 | |
220 | ./bin/gmg dbupdate | |
221 | ||
222 | to populate the database with the MediaGoblin data structures. | |
223 | ||
224 | ||
4e893b6e | 225 | Test the Server |
226 | ~~~~~~~~~~~~~~~ | |
e260065a | 227 | |
4e893b6e | 228 | At this point MediaGoblin should be properly installed. You can |
076bf0cf | 229 | test the deployment with the following command:: |
e260065a | 230 | |
076bf0cf | 231 | ./lazyserver.sh --server-name=broadcast |
e260065a | 232 | |
4e893b6e | 233 | You should be able to connect to the machine on port 6543 in your |
234 | browser to confirm that the service is operable. | |

236 | .. _webserver-config: |
237 | ||
4e893b6e | 238 | Connect the Webserver to MediaGoblin with FastCGI |
239 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
56d507b6 | 240 | |
94011579 | 241 | This section describes how to configure MediaGoblin to work via |
076bf0cf | 242 | FastCGI. Our configuration example will use nginx, however, you may |
4e893b6e | 243 | use any webserver of your choice as long as it supports the FastCGI |
244 | protocol. If you do not already have a web server, consider nginx, as | |
245 | the configuration files may be more clear than the | |
246 | alternatives. | |
247 | ||
248 | Create a configuration file at | |
249 | ``/srv/mediagoblin.example.org/nginx.conf`` and create a symbolic link | |
250 | into a directory that will be included in your ``nginx`` configuration | |
251 | (e.g. "``/etc/nginx/sites-enabled`` or ``/etc/nginx/conf.d``) with | |
076bf0cf | 252 | one of the following commands (as the root user):: |
4e893b6e | 253 | |
076bf0cf WKG |
254 | ln -s /srv/mediagoblin.example.org/nginx.conf /etc/nginx/conf.d/ |
255 | ln -s /srv/mediagoblin.example.org/nginx.conf /etc/nginx/sites-enabled/ | |
4e893b6e | 256 | |
257 | Modify these commands and locations depending on your preferences and | |
258 | the existing configuration of your nginx instance. The contents of | |
076bf0cf WKG |
259 | this ``nginx.conf`` file should be modeled on the following:: |
260 | ||

076bf0cf | 314 | } |
4e893b6e | 315 | |
316 | Now, nginx instance is configured to serve the MediaGoblin | |
317 | application. Perform a quick test to ensure that this configuration | |
318 | works. Restart nginx so it picks up your changes, with a command that | |
076bf0cf | 319 | resembles one of the following (as the root user):: |
4e893b6e | 320 | |
076bf0cf WKG |
321 | sudo /etc/init.d/nginx restart |
322 | sudo /etc/rc.d/nginx restart | |
4e893b6e | 323 | |
324 | Now start MediaGoblin. Use the following command sequence as an | |
076bf0cf | 325 | example:: |
4e893b6e | 326 | |
076bf0cf WKG |
327 | cd /srv/mediagoblin.example.org/mediagoblin/ |
328 | ./lazyserver.sh --server-name=fcgi fcgi_host=127.0.0.1 fcgi_port=26543 | |
4e893b6e | 329 | |
330 | Visit the site you've set up in your browser by visiting | |
518c5eb3 | 331 | <http://mediagoblin.example.org>. You should see MediaGoblin! |
4e893b6e | 332 | |
4e893b6e | 333 | .. note:: |
334 | ||
a085dda5 | 335 | The configuration described above is sufficient for development and |
336 | smaller deployments. However, for larger production deployments | |
337 | with larger processing requirements, see the | |
338 | ":doc:`production-deployments`" documentation. |
