DSpace 6.3 and Tomcat 9

[Marion Rupp]

Hi all,

Recently, we upgraded our DSpace testsystem (DSpace 6.3) up to Linux
Ubuntu LTS 20.04. This upgrade included Tomcat 9. Now, we have the
problem that this Tomcat version doesn´t recognize our solr index any more.

For example when I select one of our browsing categories, I get the
message "SolrException: SolrCore "search" is not available due to init
failure: Error opening new searcher..."

The reason for this seems to be the write.lock file in
dspace/solr/search/data/index (message: "File system is only readable").
I changed the write permissions, unfortunately without success.

Does anyone here has experience with Tomcat 9 and Solr?

Thank you for your feedback and kind regards,
Marion

Hi Marion,

I'm not an expert in Ubuntu but when I was trying to install DSpace 6.3 in a multi-pass instance I am taking down notes of the steps that I did. Please see below.

Install Tomcat9

sudo apt-get install tomcat9 -y

Add tomcat user to dspace user group

• sudo adduser tomcat dspace

• sudo adduser dspace tomcat

Add "ReadWritePaths=[dspace]" to the tomcat service file under the service section. For ubuntu, you can find at /lib/systemd/system/tomcat9.service. Then, please execute the following commands:

• systemctl daemon-reload

• service tomcat9 restart

For UTF-8 encoding, edit server.xml:

   <Connector port="8080" protocol="HTTP/1.1"

              minSpareThreads="25"

              enableLookups="false"

              redirectPort="8443"

              connectionTimeout="20000"

              disableUploadTimeout="true"

              URIEncoding="UTF-8"/>

Edit server.xml and change the AJP connector port:

   <Connector port="8009" UIEncoding="UTF-8" tomcatAuthentication="false"

        enableLookups="false" redirectPort="8080" protocol="AJP/1.3" secretRequired="false" />

In the portion "ReadWritePaths=[dspace]", replace it with the actual path of your dspace install directory.

Hope this helps,

Dear Euler,

Thank you for your detailed hints! Now, everything works fine with Tomcat 9 and Solr!

Kind regards,
