-XMPP/Chat Client Setup
-======================
+XMPP/Chat Setup
+===============
  
-To configure XMPP/BOSH in Noosfero you need:
+The samples of config file to configure a XMPP/BOSH server with ejabberd,
+postgresql and apache2 can be found at util/chat directory.
  
-* REST Client - http://github.com/archiloque/rest-client
-* SystemTimer - http://ph7spot.com/musings/system-timer
-* Pidgin data files - http://www.pidgin.im/
+This setup supposes that you are using Noosfero installed via Debian package
+in a production environment.
  
-If you use Debian 6.0 (squeeze):
-
-    # apt-get install librestclient-ruby pidgin-data ruby1.8-dev
-    # gem install SystemTimer
-
-The samples of config file to configure a XMPP/BOSH server with ejabberd, postgresql and apache2 can be found at util/chat directory.
-
-XMPP/Chat Server Setup
-======================
+Steps
+=====
  
 This is a step-by-step guide to get a XMPP service working, in a Debian system.
  
 ## 1. Install the required packages
  
-    # apt-get install ejabberd odbc-postgresql
+    # apt-get install ejabberd odbc-postgresql librestclient-ruby pidgin-data ruby1.8-dev
+    # gem install SystemTimer
  
 ## 2. Ejabberd configuration
  
-All the following changes must be done in config file: `/etc/ejabberd/ejabberd.cfg`
-
-### 2.1. Set the default admin user
-
-    { acl, admin, { user, "john", "www.example.com" } }.
-    { acl, admin, { user, "bart", "www.example.com" } }.
-
-### 2.2. Set the default host
-
-    { hosts, [ "www.example.com" ] }.
-
-### 2.3. Http-Bind activation
-
-    { 5280, ejabberd_http, [
-          http_bind,
-          web_admin
-       ]
-    }
-
-    (...)
-
-    { modules, [
-       {mod_http_bind, []},
-       ...
-    ] }.
-
-Ejabberd creates semi-anonymous rooms by default, but Noosfero's Jabber client needs non-anonymous room, then we need to change default params of creation rooms in ejabberd to create non-anonymous rooms.
-
-In non-anonymous rooms the jabber service sends the new occupant's full JID to all occupants in the room [[1]].
+    # cp /usr/share/noosfero/util/chat/ejabberd.cfg /etc/ejabberd/
  
-Add option "`{default_room_options, [{anonymous, false}]}`" to `/etc/ejabberd/ejabberd.cfg` in mod_muc session. See below:
+Edit the /etc/ejabberd/ejabberd.cfg file and set your domain on the first 2 lines.
  
-    { mod_muc, [
-       %%{host, "conference.@HOST@"},
-       {access, muc},
-       {access_create, muc},
-       {access_persistent, muc},
-       {access_admin, muc_admin},
-       {max_users, 500},
-       {default_room_options, [{anonymous, false}]}
-    ]},
-
-[1]: http://xmpp.org/extensions/xep-0045.html#enter-nonanon
-
-
-### 2.4. Authentication method
-
-To use Postgresql through ODBC, the following modifications must be done:
-
- * Disable the default method:
-   `{auth_method, internal}.`
-
- * Enable autheticantion through ODBC:
-   `{auth_method, odbc}.`
+## 3. Configuring Postgresql
  
- * Set database server name
-   `{odbc_server, "DSN=PostgreSQLEjabberdNoosfero"}.`
+Give permission to noosfero user create new roles, login as
+postgres user and execute:
  
+    $ psql
+    postgres=# GRANT CREATE ON DATABASE noosfero TO noosfero;
  
-### 2.5. Increase the shaper traffic limit
+Change the postgresql authentication method to md5 instead of ident,
+add the following line to the file /etc/postgresql/8.4/main/pg_hba.conf:
  
-    { shaper, normal, { maxrate, 10000000 } }.
+   # Noosfero user
+   local   noosfero    noosfero                          md5
  
+(add this line before the following line)
  
-### 2.6. Disable unused modules
+   # "local" is for Unix domain socket connections only
+   local   all         all                               ident
  
-Unused modules can be disabled, for example:
+Restart postgresql server:
  
- * s2s
- * web_admin
- * mod_pubsub
- * mod_irc
- * mod_offline
- * mod_admin_extra
- * mod_register
+    # service postgresql restart
  
+Login as noosfero user, and execute:
  
-### 2.7. Enable ODBC modules
+    $ psql -U noosfero -W noosfero < /usr/share/noosfero/util/chat/postgresql/ejabberd.sql
  
- * mod_privacy -> mod_privacy_odbc
- * mod_private -> mod_private_odbc
- * mod_roster  -> mod_roster_odbc
+(see database password in the /etc/noosfero/database.yml file)
  
-## 3. Configuring Postgresql
+This will create a new schema inside the noosfero database, called `ejabberd`.
  
-Login as noosfero user, and execute:
+Note that there should be at least one domain with `is_default = true` in
+`domains` table, otherwise people won't be able to see their friends online.
  
-    $ psql noosfero < /path/to/noosfero/util/chat/postgresql/ejabberd.sql
+## 4. ODBC configuration
  
-Where `noosfero` may need to be replace by the name of the database used for Noosfero.
+Create the following files:
  
-This will create a new schema inside the noosfero database, called `ejabberd`.
+    # cp /usr/share/noosfero/util/chat/odbc.ini /etc/
+    # cp /usr/share/noosfero/util/chat/odbcinst.ini /etc/
  
-Note `noosfero` user should have permission to create Postgresql schemas. Also, there should be at least one domain with `is_default = true` in `domains` table, otherwise people won't be able to see their friends online.
+Edit the odbc.ini file and set the password for the database user, see
+the file /etc/noosfero/database.yml to get the password.
  
-## 4. ODBC configuration
+Adjust premissions:
  
-The following files must be created:

+Setup Noosfero to use HTTPS
+===========================
+
+This document assumes that you have a fully and clean Noosfero
+installation as explained at the `INSTALL.md` file.
+
+SSL certificate
++++++++++++++++
+
+You should get a valid SSL certificate, but if you want to test
+your setup before, you could generate a self-signed certificate
+as below:
+
+    # mkdir /etc/noosfero/ssl
+    # cd /etc/noosfero/ssl
+	  # openssl genrsa 1024 > noosfero.key
+    # openssl req -new -x509 -nodes -sha1 -days $[10*365] -key noosfero.key > noosfero.cert
+    # cat noosfero.key noosfero.cert > noosfero.pem
+
+There are two ways of using SSL with Noosfero: 1) If you are not using
+Varnish; and 2) If you are using Varnish.
+
+1) If you are are not using Varnish
++++++++++++++++++++++++++++++++++++
+
+Simply do a redirect in apache to force all connections with SSL:
+
+  <VirtualHost *:8080>
+    ServerName test.stoa.usp.br
+   
+    Redirect / https://example.com/
+  </VirtualHost>
+
+And set a vhost to receive then:
+
+  <VirtualHost *:443>
+    ServerName example.com
+   
+    SSLEngine On
+    SSLCertificateFile    /etc/ssl/certs/cert.pem
+    SSLCertificateKeyFile /etc/ssl/private/cert.key
+   
+    Include /etc/noosfero/apache/virtualhost.conf
+  </VirtualHost>
+
+Be aware that if you had configured varnish, the requests won't reach
+it with this configuration.
+
+2) If you are using Varnish
++++++++++++++++++++++++++++
+
+Varnish isn't able to communicate with the SSL protocol, so we will
+need some one who do this and Pound[1] can do the job. In order to
+install it in Debian based systems:
+
+  $ sudo apt-get install pound
+
+Set Varnish to listen in other port than 80:
+
+/etc/defaults/varnish
+---------------------
+
+  DAEMON_OPTS="-a localhost:6081 \
+               -T localhost:6082 \ 
+               -f /etc/varnish/default.vcl \ 
+               -S /etc/varnish/secret \ 
+               -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
+
+Configure Pound:
+
+    # cp /usr/share/noosfero/etc/pound.cfg /etc/pound/
+
+Edit /etc/pound.cfg and set the IP and domain of your server.
+
+Configure Pound to start at system initialization:
+
+/etc/default/pound
+------------------
+
+  startup=1
+
+Set Apache to only listen to localhost:
+
+/etc/apache2/ports.conf
+-----------------------
+
+  Listen 127.0.0.1:8080
+
+Restart the services:
+
+  $ sudo service apache2 restart
+  $ sudo service varnish restart
+
+Start pound:
+
+  $ sudo service pound start
+
+[1] http://www.apsis.ch/pound
+
+Noosfero XMPP chat
+++++++++++++++++++
+
+If you want to use chat over HTTPS, then you should add the domain
+and IP of your server in the /etc/hosts file, example:
+
+/etc/hosts
+----------
+
+  192.168.1.86	mydomain.example.com

4		-To configure XMPP/BOSH in Noosfero you need:
	4	+The samples of config file to configure a XMPP/BOSH server with ejabberd,
	5	+postgresql and apache2 can be found at util/chat directory.
5	6
6		-* REST Client - http://github.com/archiloque/rest-client
7		-* SystemTimer - http://ph7spot.com/musings/system-timer
8		-* Pidgin data files - http://www.pidgin.im/
	7	+This setup supposes that you are using Noosfero installed via Debian package
	8	+in a production environment.
9	9
10		-If you use Debian 6.0 (squeeze):
11		-
12		- # apt-get install librestclient-ruby pidgin-data ruby1.8-dev
13		- # gem install SystemTimer

	10	+Steps
	11	+=====
19	12
20	13	This is a step-by-step guide to get a XMPP service working, in a Debian system.
21	14
22	15	## 1. Install the required packages
23	16
24		- # apt-get install ejabberd odbc-postgresql
	17	+ # apt-get install ejabberd odbc-postgresql librestclient-ruby pidgin-data ruby1.8-dev
	18	+ # gem install SystemTimer
25	19
26	20	## 2. Ejabberd configuration
27	21
28		-All the following changes must be done in config file: `/etc/ejabberd/ejabberd.cfg`
29		-
30		-### 2.1. Set the default admin user
31		-
32		- { acl, admin, { user, "john", "www.example.com" } }.
33		- { acl, admin, { user, "bart", "www.example.com" } }.
34		-
35		-### 2.2. Set the default host
36		-
37		- { hosts, [ "www.example.com" ] }.
38		-
39		-### 2.3. Http-Bind activation
40		-
41		- { 5280, ejabberd_http, [
42		- http_bind,
43		- web_admin
44		- ]

51		- ...
52		- ] }.
53		-
54		-Ejabberd creates semi-anonymous rooms by default, but Noosfero's Jabber client needs non-anonymous room, then we need to change default params of creation rooms in ejabberd to create non-anonymous rooms.
55		-
56		-In non-anonymous rooms the jabber service sends the new occupant's full JID to all occupants in the room [[1]].
	22	+ # cp /usr/share/noosfero/util/chat/ejabberd.cfg /etc/ejabberd/
57	23
58		-Add option "`{default_room_options, [{anonymous, false}]}`" to `/etc/ejabberd/ejabberd.cfg` in mod_muc session. See below:
	24	+Edit the /etc/ejabberd/ejabberd.cfg file and set your domain on the first 2 lines.

71		-
72		-
73		-### 2.4. Authentication method
74		-
75		-To use Postgresql through ODBC, the following modifications must be done:
76		-
77		- * Disable the default method:
78		- `{auth_method, internal}.`
79		-
80		- * Enable autheticantion through ODBC:
81		- `{auth_method, odbc}.`
	26	+## 3. Configuring Postgresql
82	27
83		- * Set database server name
84		- `{odbc_server, "DSN=PostgreSQLEjabberdNoosfero"}.`
	28	+Give permission to noosfero user create new roles, login as
	29	+postgres user and execute:
85	30
	31	+ $ psql
	32	+ postgres=# GRANT CREATE ON DATABASE noosfero TO noosfero;
86	33
87		-### 2.5. Increase the shaper traffic limit
	34	+Change the postgresql authentication method to md5 instead of ident,
	35	+add the following line to the file /etc/postgresql/8.4/main/pg_hba.conf:
88	36
89		- { shaper, normal, { maxrate, 10000000 } }.
	37	+ # Noosfero user
	38	+ local noosfero noosfero md5
90	39
	40	+(add this line before the following line)
91	41
92		-### 2.6. Disable unused modules
	42	+ # "local" is for Unix domain socket connections only
	43	+ local all all ident
93	44
94		-Unused modules can be disabled, for example:
	45	+Restart postgresql server:

102		- * mod_register
	47	+ # service postgresql restart
103	48
	49	+Login as noosfero user, and execute:
104	50
105		-### 2.7. Enable ODBC modules
	51	+ $ psql -U noosfero -W noosfero < /usr/share/noosfero/util/chat/postgresql/ejabberd.sql

	5	+installation as explained at the `INSTALL.md` file.
	6	+
	7	+SSL certificate
	8	++++++++++++++++
	9	+
	10	+You should get a valid SSL certificate, but if you want to test
	11	+your setup before, you could generate a self-signed certificate
	12	+as below:
	13	+
	14	+ # mkdir /etc/noosfero/ssl
	15	+ # cd /etc/noosfero/ssl
	16	+ # openssl genrsa 1024 > noosfero.key
	17	+ # openssl req -new -x509 -nodes -sha1 -days $[10*365] -key noosfero.key > noosfero.cert
	18	+ # cat noosfero.key noosfero.cert > noosfero.pem
	19	+
	20	+There are two ways of using SSL with Noosfero: 1) If you are not using
	21	+Varnish; and 2) If you are using Varnish.
	22	+
	23	+1) If you are are not using Varnish
	24	++++++++++++++++++++++++++++++++++++
	25	+
	26	+Simply do a redirect in apache to force all connections with SSL:
	27	+
	28	+ <VirtualHost *:8080>
	29	+ ServerName test.stoa.usp.br
	30	+
	31	+ Redirect / https://example.com/
	32	+ </VirtualHost>
	33	+
	34	+And set a vhost to receive then:
	35	+
	36	+ <VirtualHost *:443>
	37	+ ServerName example.com
	38	+
	39	+ SSLEngine On
	40	+ SSLCertificateFile /etc/ssl/certs/cert.pem
	41	+ SSLCertificateKeyFile /etc/ssl/private/cert.key
	42	+
	43	+ Include /etc/noosfero/apache/virtualhost.conf
	44	+ </VirtualHost>
	45	+
	46	+Be aware that if you had configured varnish, the requests won't reach
	47	+it with this configuration.
	48	+
	49	+2) If you are using Varnish
	50	++++++++++++++++++++++++++++
	51	+
	52	+Varnish isn't able to communicate with the SSL protocol, so we will
	53	+need some one who do this and Pound[1] can do the job. In order to
	54	+install it in Debian based systems:
	55	+
	56	+ $ sudo apt-get install pound
	57	+
	58	+Set Varnish to listen in other port than 80:
	59	+
	60	+/etc/defaults/varnish
	61	+---------------------
	62	+
	63	+ DAEMON_OPTS="-a localhost:6081 \
	64	+ -T localhost:6082 \
	65	+ -f /etc/varnish/default.vcl \
	66	+ -S /etc/varnish/secret \
	67	+ -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"
	68	+
	69	+Configure Pound:
	70	+
	71	+ # cp /usr/share/noosfero/etc/pound.cfg /etc/pound/
	72	+
	73	+Edit /etc/pound.cfg and set the IP and domain of your server.
	74	+
	75	+Configure Pound to start at system initialization:
	76	+
	77	+/etc/default/pound
	78	+------------------
	79	+
	80	+ startup=1
	81	+
	82	+Set Apache to only listen to localhost:
	83	+
	84	+/etc/apache2/ports.conf
	85	+-----------------------
	86	+
	87	+ Listen 127.0.0.1:8080
	88	+
	89	+Restart the services:
	90	+
	91	+ $ sudo service apache2 restart
	92	+ $ sudo service varnish restart
	93	+
	94	+Start pound:
	95	+
	96	+ $ sudo service pound start
	97	+
	98	+[1] http://www.apsis.ch/pound
	99	+
	100	+Noosfero XMPP chat
	101	+++++++++++++++++++
	102	+
	103	+If you want to use chat over HTTPS, then you should add the domain
	104	+and IP of your server in the /etc/hosts file, example:
	105	+
	106	+/etc/hosts
	107	+----------
	108	+
	109	+ 192.168.1.86 mydomain.example.com
	110	+
	111	+Also, it's recomended that you remove lines above from the file
	112	+`/etc/apache2/sites-enabled/noosfero`:
	113	+
	114	+ RewriteEngine On
	115	+ Include /usr/share/noosfero/util/chat/apache/xmpp.conf
