I just see that solr runs as the user solr when started by root
with service solr start. From within the console startet it runs
as user root and the creation of a core does not fail then.
I must be a permissionproblem when solr runs as the user solr
altough all the files and folders in /var/solr are owned by
the user solr.
# ll solr
insgesamt 16
drwxr-x--- 2 solr users 4096 23. Mai 00:48 data
-rw-r----- 1 solr users 977 22. Mai 13:37 log4j.properties
drwxr-x--- 2 solr users 4096 23. Mai 00:47 logs
-rw-r--r-- 1 solr users 6 23. Mai 00:47 solr-8983.pid
I get an AccessDeniedException.
In the log I see this
