@@ -254,320 +254,348 @@ Certificate Checks : optional
 

	
 
    DEMAND
 
        A server certificate is requested and must be provided and
 
        authenticated for the session to proceed.
 

	
 
    HARD
 
        The same as DEMAND.
 

	
 
.. _Base DN:
 

	
 
Base DN : required
 
    The Distinguished Name (DN) where searches for users will be performed.
 
    Searches can be controlled by `LDAP Filter`_ and `LDAP Search Scope`_.
 

	
 
.. _LDAP Filter:
 

	
 
LDAP Filter : optional
 
    A LDAP filter defined by RFC 2254.  This is more useful when `LDAP
 
    Search Scope`_ is set to SUBTREE.  The filter is useful for limiting
 
    which LDAP objects are identified as representing Users for
 
    authentication.  The filter is augmented by `Login Attribute`_ below.
 
    This can commonly be left blank.
 

	
 
.. _LDAP Search Scope:
 

	
 
LDAP Search Scope : required
 
    This limits how far LDAP will search for a matching object.
 

	
 
    BASE
 
        Only allows searching of `Base DN`_ and is usually not what you
 
        want.
 

	
 
    ONELEVEL
 
        Searches all entries under `Base DN`_, but not Base DN itself.
 

	
 
    SUBTREE
 
        Searches all entries below `Base DN`_, but not Base DN itself.
 
        When using SUBTREE `LDAP Filter`_ is useful to limit object
 
        location.
 

	
 
.. _Login Attribute:
 

	
 
Login Attribute : required        
 
    The LDAP record attribute that will be matched as the USERNAME or
 
    ACCOUNT used to connect to RhodeCode.  This will be added to `LDAP
 
    Filter`_ for locating the User object.  If `LDAP Filter`_ is specified as
 
    "LDAPFILTER", `Login Attribute`_ is specified as "uid" and the user has
 
    connected as "jsmith" then the `LDAP Filter`_ will be augmented as below
 
    ::
 

	
 
        (&(LDAPFILTER)(uid=jsmith))
 

	
 
.. _ldap_attr_firstname:
 

	
 
First Name Attribute : required
 
    The LDAP record attribute which represents the user's first name.
 

	
 
.. _ldap_attr_lastname:
 

	
 
Last Name Attribute : required
 
    The LDAP record attribute which represents the user's last name.
 

	
 
.. _ldap_attr_email:
 

	
 
Email Attribute : required
 
    The LDAP record attribute which represents the user's email address.
 

	
 
If all data are entered correctly, and python-ldap_ is properly installed
 
users should be granted access to RhodeCode with ldap accounts.  At this
 
time user information is copied from LDAP into the RhodeCode user database.
 
This means that updates of an LDAP user object may not be reflected as a
 
user update in RhodeCode.
 

	
 
If You have problems with LDAP access and believe You entered correct
 
information check out the RhodeCode logs, any error messages sent from LDAP
 
will be saved there.
 

	
 
Active Directory
 
''''''''''''''''
 

	
 
RhodeCode can use Microsoft Active Directory for user authentication.  This
 
is done through an LDAP or LDAPS connection to Active Directory.  The
 
following LDAP configuration settings are typical for using Active
 
Directory ::
 

	
 
 Base DN              = OU=SBSUsers,OU=Users,OU=MyBusiness,DC=v3sys,DC=local
 
 Login Attribute      = sAMAccountName
 
 First Name Attribute = givenName
 
 Last Name Attribute  = sn
 
 E-mail Attribute     = mail
 

	
 
All other LDAP settings will likely be site-specific and should be
 
appropriately configured.
 

	
 

	
 

	
 
Hook management
 
---------------
 

	
 
Hooks can be managed in similar way to this used in .hgrc files.
 
To access hooks setting click `advanced setup` on Hooks section of Mercurial
 
Settings in Admin. 
 

	
 
There are 4 built in hooks that cannot be changed (only enable/disable by
 
checkboxes on previos section).
 
To add another custom hook simply fill in first section with 
 
<name>.<hook_type> and the second one with hook path. Example hooks
 
can be found at *rhodecode.lib.hooks*. 
 

	
 

	
 
Setting Up Celery
 
-----------------
 

	
 
Since version 1.1 celery is configured by the rhodecode ini configuration files.
 
Simply set use_celery=true in the ini file then add / change the configuration 
 
variables inside the ini file.
 

	
 
Remember that the ini files use the format with '.' not with '_' like celery.
 
So for example setting `BROKER_HOST` in celery means setting `broker.host` in
 
the config file.
 

	
 
In order to start using celery run::
 

	
 
 paster celeryd <configfile.ini>
 

	
 

	
 
.. note::
 
   Make sure you run this command from the same virtualenv, and with the same 
 
   user that rhodecode runs.
 
   
 
HTTPS support
 
-------------
 

	
 
There are two ways to enable https:
 

	
 
- Set HTTP_X_URL_SCHEME in your http server headers, than rhodecode will
 
  recognize this headers and make proper https redirections
 
- Alternatively, change the `force_https = true` flag in the ini configuration 
 
  to force using https, no headers are needed than to enable https
 

	
 

	
 
Nginx virtual host example
 
--------------------------
 

	
 
Sample config for nginx using proxy::
 

	
 
    server {
 
       listen          80;
 
       server_name     hg.myserver.com;
 
       access_log      /var/log/nginx/rhodecode.access.log;
 
       error_log       /var/log/nginx/rhodecode.error.log;
 
       location / {
 
               root /var/www/rhodecode/rhodecode/public/;
 
               if (!-f $request_filename){
 
                   proxy_pass      http://127.0.0.1:5000;
 
               }
 
               #this is important if you want to use https !!!
 
               proxy_set_header X-Url-Scheme $scheme;
 
               include         /etc/nginx/proxy.conf;  
 
       }
 
    }  
 
  
 
Here's the proxy.conf. It's tuned so it will not timeout on long
 
pushes or large pushes::
 

	
 
    proxy_redirect              off;
 
    proxy_set_header            Host $host;
 
    proxy_set_header            X-Host $http_host;
 
    proxy_set_header            X-Real-IP $remote_addr;
 
    proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
 
    proxy_set_header            Proxy-host $proxy_host;
 
    client_max_body_size        400m;
 
    client_body_buffer_size     128k;
 
    proxy_buffering             off;
 
    proxy_connect_timeout       7200;
 
    proxy_send_timeout          7200;
 
    proxy_read_timeout          7200;
 
    proxy_buffers               8 32k;
 
 
 
Also, when using root path with nginx you might set the static files to false
 
in the production.ini file::
 

	
 
    [app:main]
 
      use = egg:rhodecode
 
      full_stack = true
 
      static_files = false
 
      lang=en
 
      cache_dir = %(here)s/data
 

	
 
In order to not have the statics served by the application. This improves speed.
 

	
 

	
 
Apache virtual host example
 
---------------------------
 
Apache virtual host reverse proxy example
 
-----------------------------------------
 

	
 
Here is a sample configuration file for apache using proxy::
 

	
 
    <VirtualHost *:80>
 
            ServerName hg.myserver.com
 
            ServerAlias hg.myserver.com
 
    
 
            <Proxy *>
 
              Order allow,deny
 
              Allow from all
 
            </Proxy>
 
    
 
            #important !
 
            #Directive to properly generate url (clone url) for pylons
 
            ProxyPreserveHost On
 
    
 
            #rhodecode instance
 
            ProxyPass / http://127.0.0.1:5000/
 
            ProxyPassReverse / http://127.0.0.1:5000/
 
            
 
            #to enable https use line below
 
            #SetEnvIf X-Url-Scheme https HTTPS=1
 
            
 
    </VirtualHost>

Apache as subdirectory
 
----------------------
 

	
 
Apache subdirectory part::
 

	
 
    <Location /<someprefix> >
 
      ProxyPass http://127.0.0.1:5000/<someprefix>
 
      ProxyPassReverse http://127.0.0.1:5000/<someprefix>
 
      SetEnvIf X-Url-Scheme https HTTPS=1
 
    </Location> 
 

	
 
Besides the regular apache setup you will need to add the following line
 
into [app:main] section of your .ini file::
 

	
 
    filter-with = proxy-prefix
 

	
 
Add the following at the end of the .ini file::
 

	
 
    [filter:proxy-prefix]
 
    use = egg:PasteDeploy#prefix
 
    prefix = /<someprefix> 
 

	
 

	
 
then change <someprefix> into your choosen prefix
 

	
 
Apache's WSGI config
 
--------------------
 

	
 
Alternatively, RhodeCode can be set up with Apache under mod_wsgi. For
 
that, you'll need to:
 

	
 
- Install mod_wsgi. If using a Debian-based distro, you can install
 
  the package libapache2-mod-wsgi::
 
    aptitude install libapache2-mod-wsgi
 
- Enable mod_wsgi::
 
    a2enmod wsgi
 
- Create a wsgi dispatch script, like the one below. Make sure you
 
  check the paths correctly point to where you installed RhodeCode
 
  and its Python Virtual Environment.
 
- Enable the WSGIScriptAlias directive for the wsgi dispatch script,
 
  as in the following example. Once again, check the paths are
 
  correctly specified.
 

	
 
Here is a sample excerpt from an Apache Virtual Host configuration file::
 

	
 
    WSGIDaemonProcess pylons user=www-data group=www-data processes=1 \
 
        threads=4 \
 
        python-path=/home/web/rhodecode/pyenv/lib/python2.6/site-packages
 
    WSGIScriptAlias / /home/web/rhodecode/dispatch.wsgi
 

	
 
Example wsgi dispatch script::
 

	
 
    import os
 
    os.environ["HGENCODING"] = "UTF-8"
 
    os.environ['PYTHON_EGG_CACHE'] = '/home/web/rhodecode/.egg-cache'
 
    
 
    # sometimes it's needed to set the curent dir
 
    os.chdir('/home/web/rhodecode/') 
 
    
 
    import site
 
    site.addsitedir("/home/web/rhodecode/pyenv/lib/python2.6/site-packages")
 
    
 
    from paste.deploy import loadapp
 
    from paste.script.util.logging_config import fileConfig
 

	
 
    fileConfig('/home/web/rhodecode/production.ini')
 
    application = loadapp('config:/home/web/rhodecode/production.ini')
 

	
 
Note: when using mod_wsgi you'll need to install the same version of
 
Mercurial that's inside RhodeCode's virtualenv also on the system's Python
 
environment.
 

	
 

	
 
Other configuration files
 
-------------------------
 

	
 
Some example init.d scripts can be found here, for debian and gentoo:
 

	
 
https://rhodecode.org/rhodecode/files/tip/init.d
 

	
 

	
 
Troubleshooting
 
---------------
 

	
 
:Q: **Missing static files?**
 
:A: Make sure either to set the `static_files = true` in the .ini file or
 
   double check the root path for your http setup. It should point to 
 
   for example:
 
   /home/my-virtual-python/lib/python2.6/site-packages/rhodecode/public
 
   
 
| 
 

	
 
:Q: **Can't install celery/rabbitmq**
 
:A: Don't worry RhodeCode works without them too. No extra setup is required.
 

	
 
|
 
 
 
:Q: **Long lasting push timeouts?**
 
:A: Make sure you set a longer timeouts in your proxy/fcgi settings, timeouts
 
    are caused by https server and not RhodeCode.
 
    
 
| 
 

	
 
:Q: **Large pushes timeouts?**
 
:A: Make sure you set a proper max_body_size for the http server.
 

	
 
|
 

	
 
:Q: **Apache doesn't pass basicAuth on pull/push?**
 
:A: Make sure you added `WSGIPassAuthorization true`.
