In an Alfresco setup, we find important directories under
alf_data (dir.root) in a default installation :
/opt/alfresco51e /opt/alfresco51e/alf_data contentstore --> Alfresco binaries are located here contentstore.deleted --> Alfresco binaries at the final of the deletion lifecycle solr4Backup --> Alfresco Backups for SOLR indices (3 snapshots) solr4 --> SOLR indices
In most cases, these directories are reconfigured:
- contentstore is a large scalable remote NFS drive, which is better
mounted out of alf_data directory - contentstore.deleted may be deleted periodically via cron job safely
- solr4 indices should be in the fastest disk as possible for better
perfomance indexing and searching - solr4 indices folder should not be copied in a hot backup procedure
For example, a more suitable directory structure may be something
like this:
/opt/alfresco51e /opt/data contentstore contentstore.deleted /opt/solr4Backup /opt/solr4
where /opt/data is usually a NFS mount point, and /opt/solr4 a faster
local disk. For this new setup, we have to make some changes in
Alfresco configuration according to:
In
alfresco-global.properties: (in /opt/alfresco51e/tomcat/shared/classes)
dir.root=/opt/alfresco51e/alf_data # Contentstore dir.contentstore=/opt/data/contentstore dir.contentstore.deleted=/opt/data/contentstore.deleted # Backup indices solr.backup.archive.remoteBackupLocation=/opt/solr4Backup/archive solr.backup.alfresco.remoteBackupLocation=/opt/solr4Backup/alfresco
Besides, we need to modify data.dir.root variable in both solrcore.properties
- /opt/alfresco51e/solr4/archive-SpacesStore/conf/solrcore.properties
- /opt/alfresco51e/solr4/workspace-SpacesStore/conf/solrcore.properties
#data.dir.root=/opt/alfresco51e/alf_data/solr4/index data.dir.root=/opt/solr4/index
And finally in /opt/alfresco51e/tomcat/conf/Catalina/localhost/solr4.xml
<?xml version="1.0" encoding="utf-8"?> <Context debug="0" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/opt/alfresco51e/solr4" override="true"/> <!-- <Environment name="solr/model/dir" type="java.lang.String" value="/opt/alfresco51e/alf_data/solr4/model" override="true"/> <Environment name="solr/content/dir" type="java.lang.String" value="/opt/alfresco51e/alf_data/solr4/content" override="true"/> --> <Environment name="solr/model/dir" type="java.lang.String" value="/opt/solr4/model" override="true"/> <Environment name="solr/content/dir" type="java.lang.String" value="/opt/solr4/content" override="true"/> </Context>
With this configuration, we can make for example easier hot backups
at 5:30 AM for the new paths,
/opt/solr4Backup --> backups by default at 2 AM and 4 AM /opt/data/contentstore --> better an incremental or differential backup /opt/alfresco51e --> tomcat config. & modules
with the corresponding dump for the database.
Notes:
- Commented parts are related to original config
- This config is valid for Alfresco 5, with SOLR4 subsystem
