Hello Chris, You dropped a vital piece of information about the Linux flavor you are using so I'm assuming a Debian derivative. It's better to start a fresh Solr installation by removing the old Solr installation and following the steps you see below.
a) mkdir /build b) cd /build c) wget https://downloads.apache.org/lucene/solr/8.11.1/solr-8.11.1.tgz d) tar xzf solr-8.11.1.tgz solr-8.11.1/bin/install_solr_service.sh --strip-components=2 e) vi ./install_solr_service.sh # You need to change SOLR_USER=solr to SOLR_USER=tomcat in /etc/default/install_solr_service.sh file. tomcat is the user which has write permission over dspace folder if not replace tomcat with the user you picked for dspace. f) bash ./install_solr_service.sh solr-8.11.1.tgz g) vi /etc/default/solr.in.sh # You need to add dspace folders in Solr allowed paths. SOLR_OPTS="$SOLR_OPTS -Dsolr.allowPaths=/opt/dspace/solr/statistics,/opt/dspace/temp/solr-data" h) cp -r /opt/dspace/solr/* /var/solr/data/ # Do this step after installing dspace. You need to change /opt/dspace to the folder you installed dspace into. i) chown -R tomcat:tomcat /var/solr/data/ # You need to change the user and the group if it differs from the user and group you chose for dspace. j) systemctl enable solr k) systemctl restart solr *** You might fall into this issue at a later stage. Running /opt/dspace/bin/dspace solr-reindex-statistics for the first time will complain with the error message you see below but running it again will complete successfully ( I think the error shows up because of the existence of /opt/dspace/solr/statistics/core.properties file which gets deleted at the first run) . Maybe Tim can shed some light on this. ### error message ### Could not create a new core in /opt/dspace/solr/statistics as another core is already defined there ### end of error message ### ######## Steps to uninstall Solr on Ubuntu manually ########## systemctl stop solr rm -r /var/solr rm -r /opt/solr-8.x.x rm -r /opt/solr rm /etc/init.d/solr deluser --remove-home solr deluser --group solr update-rc.d -f solr remove rm -rf /etc/default/solr.in.sh ################################################# Mohammed On Monday, December 20, 2021 at 5:49:39 PM UTC+3 DSpace Technical Support wrote: > Hi Chris, > > The 'solr' user should be created by default when installing Apache Solr. > In any case, Apache Solr recommends *not* running Solr as root.
