Old configuration example for nginx reverse proxy configuration works only partially on version 1.6.2. Browser is able to load Gerrit's host page but for javascript files it gets 404. With this small update to configuration everything works fine. Change-Id: Ie5de667e5df0e35984db10bf00187aa3d3068b33 Signed-off-by: Dariusz Luksza <dariusz@luksza.org>

= Gerrit Code Review - Reverse Proxy
|
|
|
|
== Description
|
|
|
|
Gerrit can be configured to run behind a third-party web server.
|
|
This allows the other web server to bind to the privileged port 80
|
|
(or 443 for SSL), as well as offloads the SSL processing overhead
|
|
from Java to optimized native C code.
|
|
|
|
|
|
== Gerrit Configuration
|
|
|
|
Ensure `'$site_path'/etc/gerrit.config` has the property
|
|
link:config-gerrit.html#httpd.listenUrl[httpd.listenUrl] configured
|
|
to use 'proxy-http://' or 'proxy-https://' and a free port number.
|
|
This may have already been configured if proxy support was enabled
|
|
during 'init'.
|
|
|
|
----
|
|
[httpd]
|
|
listenUrl = proxy-http://127.0.0.1:8081/r/
|
|
----
|
|
|
|
|
|
== Apache 2 Configuration
|
|
|
|
To run Gerrit behind an Apache server using 'mod_proxy', enable the
|
|
necessary Apache2 modules:
|
|
|
|
----
|
|
a2enmod proxy_http
|
|
a2enmod ssl ; # optional, needed for HTTPS / SSL
|
|
----
|
|
|
|
Configure an Apache VirtualHost to proxy to the Gerrit daemon,
|
|
setting the 'ProxyPass' line to use the 'http://' URL configured
|
|
above. Ensure the path of ProxyPass and httpd.listenUrl match,
|
|
or links will redirect to incorrect locations.
|
|
|
|
----
|
|
<VirtualHost *>
|
|
ServerName review.example.com
|
|
|
|
ProxyRequests Off
|
|
ProxyVia Off
|
|
ProxyPreserveHost On
|
|
|
|
<Proxy *>
|
|
Order deny,allow
|
|
Allow from all
|
|
# Use following line instead of the previous two on Apache >= 2.4
|
|
# Require all granted
|
|
</Proxy>
|
|
|
|
AllowEncodedSlashes On
|
|
ProxyPass /r/ http://127.0.0.1:8081/r/ nocanon
|
|
</VirtualHost>
|
|
----
|
|
|
|
The two options 'AllowEncodedSlashes On' and 'ProxyPass .. nocanon' are required
|
|
since Gerrit 2.6.
|
|
|
|
=== SSL
|
|
|
|
To enable Apache to perform the SSL processing, use 'proxy-https://'
|
|
in httpd.listenUrl within Gerrit's configuration file, and enable
|
|
the SSL engine in the Apache VirtualHost block:
|
|
|
|
----
|
|
<VirtualHost *:443>
|
|
SSLEngine on
|
|
SSLCertificateFile conf/server.crt
|
|
SSLCertificateKeyFile conf/server.key
|
|
|
|
... same as above ...
|
|
</VirtualHost>
|
|
----
|
|
|
|
See the Apache 'mod_ssl' documentation for more details on how to
|
|
configure SSL within the server, like controlling how strong of an
|
|
encryption algorithm is required.
|
|
|
|
=== Troubleshooting
|
|
|
|
If you are encountering 'Page Not Found' errors when opening the change
|
|
screen, your Apache proxy is very likely decoding the passed URL.
|
|
Make sure to either use 'AllowEncodedSlashes On' together with
|
|
'ProxyPass .. nocanon' or alternatively a 'mod_rewrite' configuration with
|
|
'AllowEncodedSlashes NoDecode' set.
|
|
|
|
|
|
== Nginx Configuration
|
|
|
|
To run Gerrit behind an Nginx server, use a server statement such
|
|
as this one:
|
|
|
|
----
|
|
server {
|
|
listen 80;
|
|
server_name review.example.com;
|
|
|
|
location ^~ /r/ {
|
|
proxy_pass http://127.0.0.1:8081;
|
|
proxy_set_header X-Forwarded-For $remote_addr;
|
|
proxy_set_header Host $host;
|
|
}
|
|
}
|
|
----
|
|
|
|
=== SSL
|
|
|
|
To enable Nginx to perform the SSL processing, use 'proxy-https://'
|
|
in httpd.listenUrl within Gerrit's configuration file, and enable
|
|
the SSL engine in the Nginx server statement:
|
|
|
|
----
|
|
server {
|
|
listen 443;
|
|
server_name review.example.com;
|
|
|
|
ssl on;
|
|
ssl_certificate conf/server.crt;
|
|
ssl_certificate_key conf/server.key;
|
|
|
|
... same as above ...
|
|
}
|
|
----
|
|
|
|
See the Nginx 'http ssl module' documentation for more details on
|
|
how to configure SSL within the server, like controlling how strong
|
|
of an encryption algorithm is required.
|
|
|
|
=== Troubleshooting
|
|
|
|
If you are encountering 'Page Not Found' errors when opening the change
|
|
screen, your Nginx proxy is very likely decoding the passed URL.
|
|
Make sure to use a 'proxy_pass' URL without any path (esp. no trailing
|
|
'/' after the 'host:port').
|
|
|
|
If you are using Apache httpd server with mod_jk and AJP connector, add
|
|
the following option to your httpd.conf directly or included from another
|
|
file:
|
|
