4 We've tried very hard to ensure that Friendika will run on commodity hosting
5 platforms - such as those used to host Wordpress blogs and Drupal websites.
6 But be aware that Friendika is more than a simple web application. It is a
7 complex communications system which more closely resembles an email server
8 than a web server. For reliability and performance, messages are delivered in
9 the background and are queued for later delivery when sites are down. This
10 kind of functionality requires a bit more of the host system than the typical
11 blog. Not every PHP/MySQL hosting provider will be able to support Friendika.
12 Many will. But please review the requirements and confirm these with your
13 hosting provider prior to installation.
15 Before you begin: Choose a domain name or subdomain name for your server.
16 Put some thought into this - because changing it is currently not-supported.
17 Things will break, and some of your friends may have difficulty communicating
18 with you. We plan to address this limitation in a future release.
22 - Apache with mod-rewrite enabled and "Options All" so you can use a
25 - PHP 5.2+. The later the better. You'll need 5.3 for encryption of key
26 exchange conversations
27 - PHP *command line* access with register_argc_argv set to true in the
29 - curl, gd, mysql, mbstring, and openssl extensions
30 - some form of email server or email gateway such that PHP mail() works
31 - mcrypt (optional; used for end-to-end message encryption)
35 - ability to schedule jobs with cron (Linux/Mac) or Scheduled Tasks
36 (Windows) [Note: other options are presented in Section 8 of this document]
38 - Installation into a top-level domain or sub-domain (without a
39 directory/path component in the URL) is preferred. Directory paths will
40 not be as convenient to use and have not been thoroughly tested.
42 [Dreamhost.com offers all of the necessary hosting features at a
43 reasonable price. If your hosting provider doesn't allow Unix shell access,
44 you might have trouble getting everything to work.]
46 2. Unpack the Friendika files into the root of your web server document area.
48 - If you copy the directory tree to your webserver, make sure
49 that you also copy .htaccess - as "dot" files are often hidden
50 and aren't normally copied.
52 3. Create an empty database and note the access details (hostname, username,
53 password, database name).
56 4. If you know in advance that it will be impossible for the web server to
57 write or create files in your web directory, create an empty file called
58 .htconfig.php and make it writable by the web server.
60 5. Visit your website with a web browser and follow the instructions. Please
61 note any error messages and correct these before continuing.
63 6. *If* the automated installation fails for any reason, check the following:
65 - ".htconfig.php" exists
66 If not, edit htconfig.php and change system settings. Rename
68 - Database is populated.
69 If not, import the contents of "database.sql" with phpmyadmin
72 7. At this point visit your website again, and register your personal account.
73 Registration errors should all be recoverable automatically.
74 If you get any *critical* failure at this point, it generally indicates the
75 database was not installed correctly. You might wish to move/rename
76 .htconfig.php to another name and empty (called 'dropping') the database
77 tables, so that you can start fresh.

85 8. Set up a cron job or scheduled task to run the poller once every 5-10
86 minutes to pick up the recent "public" postings of your friends. Example:
88 cd /base/directory; /path/to/php include/poller.php
90 Change "/base/directory", and "/path/to/php" as appropriate for your situation.
92 If you are using a Linux server, run "crontab -e" and add a line like the
93 one shown, substituting for your unique paths and settings:
95 */10 * * * * cd /home/myname/mywebsite; /usr/bin/php include/poller.php
97 You can generally find the location of PHP by executing "which php". If you
98 have troubles with this section please contact your hosting provider for
99 assistance. Friendika will not work correctly if you cannot perform this step.
101 Alternative: You may be able to use the 'poormancron' plugin to perform this
102 step if you are using a recent Friendika release. To do this, edit the file
103 ".htconfig.php" and look for a line describing your plugins. On a fresh
104 installation, it will look like
106 $a->config['system']['addon'] = 'js_upload';
108 This indicates the "js_upload" addon module is enabled. You may add additional
109 addons/plugins using this same line in the configuration file. Change it to
112 $a->config['system']['addon'] = 'js_upload,poormancron';
114 and save your changes.

154 First check your file permissions. Your website and all contents must
155 generally be world-readable.
157 Ensure that mod-rewite is installed and working, and that your
158 .htaccess file is being used. To verify the latter, create a file test.out
159 containing the word "test" in the top directory of Friendika, make it world
160 readable and point your web browser to
162 http://yoursitenamehere.com/test.out
164 This file should be blocked. You should get a permission denied message.
166 If you see the word "test" your Apache configuration is not allowing
167 your .htaccess file to be used (there are rules in this file to block access
168 to any file with .out at the end, as these are typically used for system logs).
170 Make certain the .htaccess file exists and is readable by everybody, then
171 look for the existence of "AllowOverride None" in the Apache server
172 configuration for your site. This will need to be changed to
175 If you do not see the word "test", your .htaccess is working, but it is
176 likely that mod-rewrite is not installed in your web server or is not working.

185 you need to change either of these and can not figure out how. There is
