<div dir="ltr">I remember running into similar issues with jboss/wildfly about a year ago where the maintainer moved folders around and created a neat little web of symlinks. The problems is that while its generally good practice to put configuration in /etc, pids in /var/run, logs in /var/log, etc. it can sometimes be problematic for for software not written this way. Java applications like jetty, tomcat, wildfly, jboss, solr, etc. are much easier to maintain and run when they are just left as is.<div><br></div><div>I've resolved to not using slackbuilds for any java programs and install I manually extract and run as my user account. (The only exception is apache-ant, that works well)</div><div><br></div><div>It might be worth playing around with /etc/profile.d/ and adding a tomcat.* set for those variables.

As i understand this is just when you want to have multiple instances of Apache Tomcat, each one sharing some directories from $CATALINA_HOME while keeping their own configuration/libraries [1] [2] [3] [4] separated. Actually, this is what Eclipse/Netbean does, it ask you for $CATALINA_HOME and create a $CATALINA_BASE directory to manage it execution ("Create a local server").<br></div><div><br> IMHO there should not be $CATALINA_BASE **globally**, but **locally** (/etc/rc.d/rc.tomcat maybe).<br><br></div><div> But remember that /etc/rc.d/rc.tomcat has hardcoded values for $PIDFILE, $LOGFILE and $USER to work with $CATALINA_BASE so i am not sure this is the case for multiple instances. Anyway these environment variable would be uniques to each instance of tomcat (if this is the case) so a better place to define them would be $CATALINA_BASE/conf/tomcat-java.conf, which brings the next question.<br><br></div><div>* Why the configuration files are keep in /etc/tomcat?. Is this some kind of "HIER or die!"? ;-)<br><br></div><div>* And finally, why the $CATALINA_HOME/bin/*.sh files are keep with 0744 as permission? It is for some kind of security?.<br><br></div><div>I hope to make clear my questions and not generate more ;-)<br></div><div><br></div><div>- Cheers<br></div><div><br>[1] <a href="http://tomcat.apache.org/tomcat-7.0-doc/RUNNING.txt" target="_blank">http://tomcat.apache.org/tomcat-7.0-doc/RUNNING.txt</a><br>[2] <a href="http://java.dzone.com/articles/running-multiple-tomcat" target="_blank">http://java.dzone.com/articles/running-multiple-tomcat</a><br>[3] <a href="http://www.ramkitech.com/2011/07/running-multiple-tomcat-instances-on.html" target="_blank">http://www.ramkitech.com/2011/07/running-multiple-tomcat-instances-on.html</a><br>[4] <a href="http://blogs.vmware.com/vfabric/2012/10/5-scenarios-and-best-practices-for-running-multiple-instances-of-tomcat-or-tc-server.html" target="_blank">http://blogs.vmware.com/vfabric/2012/10/5-scenarios-and-best-practices-for-running-multiple-instances-of-tomcat-or-tc-server.html</a><span class="HOEnZb"><font color="#888888"><br></font></span></div><span class="HOEnZb"><font color="#888888"><div><br></div><div>-- <br><div><div dir="ltr">Antonio Hernández Blas | Oaxaca, México, Mx.<br><a href="https://github.com/nihilismus" target="_blank">https://github.com/nihilismus</a> | <a href="https://bitbucket.org/nihilismus" target="_blank">https://bitbucket.org/nihilismus</a> | <a href="https://twitter.com/nihilipster" target="_blank">https://twitter.com/nihilipster</a></div></div>
