These are the steps that worked for me installing XWiki on Ubuntu Server 16.04.01 LTS with Jetty and Postgres. I have double checked most of these steps, but not all of them so your mileage may vary. This is my first time installing the WAR version of XWiki and I've had quite a bit of help getting this far. I'd appreciate any feedback from more experienced installers if they see issues with my process. - Jared Please note that Postgres Installed with the initial Ubuntu installation Install Java ----------- sudo apt-get update sudo apt-get install default-jdk Edit /etc/environment Add JAVA_HOME=/usr/bin/java Install Jetty ----------- sudo apt-get install jetty9 Edit /etc/default/jetty9 to set the JVM parameters JAVA_OPTIONS="-server -Xms800m -Xmx1048m -Dfile.encoding=utf-8 -Djava.awt.headless=true -XX:+UseParallelGC -XX:MaxGCPauseMillis=100" Install & Configure XWiki ------------------------ Download the current WAR wget http://download.forge.ow2.org/xwiki/xwiki-enterprise-web-8.1.war Expand the WAR to the XWiki root cd /usr/share/jetty9/webapps/root sudo rm * sudo jar -xvf <path to war>/xwiki-enterprise-web-8.1.war Configure the Permanent Directory ---------------------------------- sudo mkdir /var/local/xwiki sudo chown jetty:adm /var/local/xwiki Edit /usr/share/jetty9/webapps/root/WEB-INF/xwiki.properties Uncomment # environment.permanentDirectory=/var/local/xwiki/ Configure xwiki as the the JVM root ----------------------------------- Edit /usr/share/jetty9/webapps/root/WEB-INF/xwiki.cfg (Note that this is a different config file than xwiki.properties) Uncomment # xwiki.webapppath= Configure xwiki to use the filesystem for attachments ---------------------------------------------------- Edit /usr/share/jetty9/webapps/root/WEB-INF/xwiki.cfg Uncomment the following lines and change hibernate to file # xwiki.store.attachment.hint=hibernate # xwiki.store.attachment.versioning.hint=hibernate # xwiki.store.attachment.recyclebin.hint=hibernate New Values: xwiki.store.attachment.hint=file xwiki.store.attachment.versioning.hint=file xwiki.store.attachment.recyclebin.hint=file Edit /usr/share/jetty9/webapps/root/WEB-INF/hibernate.cfg.xml to use Postgres ------------------------------------------------------------------------------ Comment out default database Uncomment Postgres section (don't forget to remove the closing comment line from the Postgres section) Install the Postgres JDBC Driver ------------------------------- cd /usr/share/jetty9/webapps/root/WEB-INF/lib sudo wget https://jdbc.postgresql.org/download/postgresql-9.4.1208.jar Set the ownership on the xwiki directory --------------------------------------- cd /usr/share/jetty9/webapps/ sudo chown -R jetty:adm root Configure Postgres ------------------- sudo -u postgres psql psql (9.5.3) Type "help" for help. postgres=# CREATE DATABASE xwiki postgres-# WITH OWNER = postgres postgres-# ENCODING = 'UNICODE' postgres-# TABLESPACE = pg_default; CREATE DATABASE postgres=# \l List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges -----------+----------+----------+-------------+-------------+----------------------- postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres xwiki | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | (4 rows) postgres=# \connect xwiki You are now connected to database "xwiki" as user "postgres". xwiki=# CREATE USER xwiki PASSWORD 'xwiki' VALID UNTIL 'infinity'; CREATE ROLE xwiki=# \du List of roles Role name | Attributes | Member of -----------+------------------------------------------------------------+----------- postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {} xwiki | Password valid until infinity | {} xwiki=# GRANT ALL ON SCHEMA public TO xwiki; GRANT xwiki=# \q Optional - Configure redirection from 80 to 8080 ------------------------------------------------ sudo iptables -A PREROUTING -t nat -p tcp --dport 80 -j REDIRECT --to-port 8080 sudo apt-get install iptables-persistent sudo bash -c "iptables-save > /etc/iptables/rules.v4" to save future changes Restart Jetty to apply changes since the initial installation -------------------------------------------------------- sudo systemctl restart jetty9
