Confluence Can't Start and Doesn't Create Logfiles due to CATALINA_HOME Being Set
Confluence does not start after running startup.sh.
Confluence's startup scripts won't override the value of
CATALINA_BASE if they've already been set. Instead, they'll assume that it defines where tomcat should be running.
Unset the variable, by either running
unset CATALINA_HOME or
unset CATALINA_BASE on Unix or Linux platforms, without the backticks, or removing
CATALINA_HOME from the relevant user's profile scripts.
