XWiki
XWiki is an open-source enterprise-ready wiki written in Java, with a focus on extensibility.
Installation
Feel free to follow along on the XWiki Installation Guide. These instructions assume you will be using Tomcat and PostgreSQL. It should not be too difficult to apply these guidelines to other combinations.
- Install PostgreSQL.
- For easier PostgreSQL administration, install phpPgAdmin.
- Install tomcat. (Do not forget tomcat-native.)
- Download the XWiki WAR file.
- Rename the WAR file to
xwiki
. - Move the WAR file into the
/var/lib/tomcatn/webapps
directory. - Tomcat should automatically extract the WAR file. If not, restart Tomcat.
- At this point, you may find that a
data
directory has appeared in/var/lib/tomcatn/webapps
. Delete it. - As root:
# cd /var/lib/tomcatn # mkdir data # chown tomcatn:tomcatn data
- Inside the
/var/lib/tomcatn/webapps/xwiki/WEB-INF
directory:- Open the
xwiki.properties
file and alter theenvironment.permanentDirectory
field to read/var/lib/tomcatn/data/xwiki
. - Open the
hibernate.cfg.xml
file and:- Comment-out the section entitled "Configuration for the default database".
- Uncomment the section entitled "PostgreSQL Configuration".
- Modify the database name (in
connection.url
), username, and password as desired.
- Open the
- Create a role and database in PostgreSQL to match the hibernate configuration.
- Install postgresql-jdbcAUR from the Arch User Repository.
- As root:
# cd /usr/share/java/tomcatn # ln -s /usr/share/java/postgresql-jdbc/postgresql-jdbc41.jar
- Restart
tomcatn.service
. - Launch the XWiki application by clicking on
/xwiki
in Tomcat Manager. - The XWiki is started with XWiki Wizard Guide to finish your configuration.
Nginx proxy configuration - Solution 1
The official Nginx guide for XWiki is not correct. There is an alternative solution which works for XWiki.
- Configure nginx site
xwiki
configuration file.
/etc/nginx/sites-available/xwiki
server { listen 80 default_server; server_name xwiki.<domain-name>; return 301 https://$host$request_uri; } server { listen [::]:443 ssl; listen 443 ssl; server_name xwiki.<domain-name>; # SSL Certificate section ssl_certificate ... ssl_certificate_key ... location = / { return 301 https://$host/xwiki; } location /xwiki { proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_cache_bypass $http_upgrade; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:8080/xwiki; } }
- Activate a server block in
sites-enabled
directoryln -s /etc/nginx/sites-available/xwiki /etc/nginx/sites-enabled/xwiki
. - Restart Nginx.
Nginx proxy configuration - Solution 2
I found that instructing nginx to proxy to http://localhost:8080/xwiki/
did not work: the generated URLs were incorrect. Contrary to what is indicated in the XWiki documentation, I could not make the URLs correct through the use of HTTP headers.
The only solution I'm aware of so far is to create a new Host
element in Tomcat's server.xml
file:
- Duplicate the existing
Host
element and alter thename
attribute to readxwiki
. - Alter the
appBase
attribute to read/var/lib/tomcat7/webapps-xwiki
. - Move the
xwiki
application from/var/lib/tomcat7/webapps/xwiki
to/var/lib/tomcat7/webapps-xwiki/ROOT
. - Restart Tomcat
- Add
xwiki
as an alias to localhost in/etc/hosts
(add it to the end of the 127.0.0.1 line). - Instruct Nginx to proxy to
http://xwiki:8080/
instead.
