Alfresco Search Services 1.3.0.1 doesn't search

[davidemd]

Hello,

I have Alfresco Community - 6.1.2 (r4fe1d0d0-b205) with Alfresco Search Services 1.3.0.1 installed with the distribution zips.
I followed "Installing and configuring Alfresco Search Services" instructions but the search function doesn't work. I configured it with mutual TLS. My OS is Suse SLES 12 sp4, openJDK 11.

When I try search anything the result is always nothing. Catalina log writes this: Catalina Error 

My alfresco-global.properties:

# SOLR

Alfesco is not able to find solr. You should check solr logs to see whether it started up properly, and check solr configuration properties too.

And the logging in the console show this:

I reviewed all configuration files of solr and are ok acording the documention.

Thanks

[narkuss]

Ok, the error now looks different... Looking at solr console seems that solr is not able to see alfresco neither, but looking at the logs seems that solr is not starting properly.

I've never seen the error shown in the logs, so let's check a couple of things. 

Firts of all, check that you have properly set JAVA_HOME environment variable. After that, check that solr is correctly getting this variable. It must be set in some of the init scripts, maybe solr.in.sh.

Finally, check that alfresco.port property is correctly set in both cores, if they already exist, alfresco and archive, specially if you are running Alfresco in another port than 8080. We found a weird behaviour when trying to set a different port for Alfresco in main solrcore.properties, solr did not take the value from there for both cores, we had to set the value in specific solrcore properties file for both cores once created.

Hope it helps to troubleshoot your problem!

Hi,

Sorry for the delay but I've had other priorities these weeks... as a lot of people in IT (and real life) these days.

I think that is related with the keystore. If i try to set dir.keystore=/opt/alfresco/alf_data/keystore in alfresco-global.properties file I see the next error in catalina.out:

if I comment that line Alfresco and Share are loaded but Solr6 is unable to search anything. Searching I found that the default dir.keystore location is classpath:alfresco/keystore that is <TOMCAT_HOME>/webapps/alfresco/WEB-INF/classes/alfresco/keystore. So I created this path and I copied the alf_data/keystore files into there but I have the same bad result.

I've already checked alfresco and solr properties, ports, paths... I also regenerated the secure keys for SSL...

Any idea?

Thanks!

Regards.

Ok I think this great post by Angel Borroy could help you a lot. It explains and shows you carefully how MTLS connection works between Alfresco and Solr, and how to configure it.

Also take a look at this other post with a similar explanation.

Hope this helps

Hi,

thanks for these 2 excellent documents, I have already found several interesting documents signed by Angel. But, in this case, I couldn't solve it in this way.

I followed all the installation and configuration steps in both Alfresco.war and Alfresco Search Services. Everything seems to be fine according to Alfresco installation guides and Angel articles.

Finally, I regenerated the keystores and certificates using generate_keystores.sh script instead of alfresco-ssl-generator tool. It's important remember copying the password.properties files to solrhome/keystore and cores /conf path, at the beginning I wasn't do it and the Solr6 start was failing. However , the error in Solr log is clear and easy to solve: 

Caused by: org.apache.solr.core.SolrResourceNotFoundException: Can't find resource '/opt/alfresco/alfresco-search-services/solrhome/keystore/ssl-keystore-passwords.properties' in classpath or '/opt/alfresco/alfresco-search-services/solrhome/archive'

I hope this could help to anyone with the same issue. 

Thanks & Regards.
