Description David Mulford 2018-06-28 17:20:23 UTC
Description of problem:

In order to run multiple instances of Tomcat on a single machine, the following article recommends labelling the /var/lib/tomcats directory with tomcat_var_lib_t. Without this, Tomcat cannot start due to permission denied errors.

Here is the article:

Here are the recommended commands from the article:

  $ sudo semanage fcontext -a -t tomcat_var_lib_t  "/var/lib/tomcats(/.*)?" 
  $ sudo restorecon -R -v /var/lib/tomcats

After discussing with other engineers, the tomcat_var_lib_t context may be a bit too liberal, as it allows read/write access to the directory; see below.

  allow tomcat_t tomcat_var_lib_t : file { ioctl read write create getattr setattr lock append unlink link rename open } ; 
  allow tomcat_t tomcat_var_lib_t : dir { ioctl read write create getattr setattr lock unlink link rename add_name remove_name reparent search rmdir open } ;

Note that this currently applies to scenarios where the RHEL tomcat package is used, and multiple instances need to be running on one server.

Comment 3 Zdenek Pytela 2018-07-03 15:58:53 UTC
The article referred to expects there were multiple directories serving different purpose created:


While tomcat_var_lib_t context would work for the tomcat_t domain process accessing files in this directory tree in terms of not producing AVC denials, there should be more confined context considered for the subdirectories, like tomcat_log_t for logs, tomcat_tmp_t for temp files etc., but this should rather be clarified with tomcat developers.
