Sergey Urushkin created SOLR-8101:
-------------------------------------
Summary: Installation script permission issues and other scripts
fixes
Key: SOLR-8101
URL: https://issues.apache.org/jira/browse/SOLR-8101
Project: Solr
Issue Type: Improvement
Components: scripts and tools
Affects Versions: 5.3.1
Reporter: Sergey Urushkin
Until [https://issues.apache.org/jira/browse/SOLR-7871] is fixed, I suggest to
improve current shell scripts. Provided patch:
* changes {{$SOLR_ENV}} default to {{/etc/default/solr.in.sh}} . This is
*security* issue. If {{solr.in.sh}} is placed in directory which is writable by
{{$SOLR_USER}}, solr process is able to write to it, and than it will be run by
root on start/shutdown.
* changes permissions. {{$SOLR_USER}} should only be able to write to
{{$SOLR_VAR_DIR , $SOLR_INSTALL_DIR/server/solr-webapp ,
$SOLR_INSTALL_DIR/server/logs}} . {{solr-webapp}} directory might be inspected
more. These directories should not be readable by other users as they may
contain personal information.
* sets {{$SOLR_USER}} home directory to {{$SOLR_VAR_DIR}} . As I can see
there is no need in {{/home/solr}} directory.
* adds quotes to unquoted variables
* adds leading zero to chmod commands
* removes group from chown commands (uses ":")
Tested on ubuntu 14.04 amd64, but changes are pretty system-independent.
