I found this page on installing xwiki on centos 7:
https://thishosting.rocks/how-to-build-your-own-wiki-with-xwiki-on-centos/Following that outline, I installed it on my SME server using:
yum install java
mkdir -p /root/addons
cd /root/addons
wget http://download.forge.ow2.org/xwiki/xwiki-enterprise-installer-generic-8.4.5-standard.jar
java -jar xwiki-enterprise-installer-generic-8.4.5-standard.jar
During install, I answered several simple/non-technical questions
I answered "No" only to the questions about adding xwiki to start menus and desktops
After install:
cd /usr/local/XWiki\ Enterprise\ 8.4.5/
./start_xwiki.sh
Wait a minute or so until the screen indicates that the server has started...
http://your-sme-server-lan-IP:8080/Still to do (assuming you want to use XWiki from off-site):
* Create either a
firewall rule,
domain proxypass or
alias/location proxypass.
* Configure XWiki to start automatically when your server reboots (sv / service / /etc/init.d / crontab)
* (I don't know about this one...) Configure XWiki to run as a non-privileged user...
