hi.
1) I have removed the previous correspondence from this email, because by now it has
become pretty much unreadable anyway.
Also, there are 2 links at the bottom of your last email (to "avg"-something). I don't
know if these are supposed to provide some additional information, but they both lead to a
page asking me to install something on my laptop, which of course I am not going to do.
2) according to the paths which you show below, it does not look like there is an overlap
between the httpd DocumentRoot and the tomcat webapps directory.
(Of course that does not show if there are any symlinks anywhere which may provide such a
connection on the sly. But let's suppose there aren't, and let's for now forget about that
red warning in the documentation.)
3) I do not really remember what the stage of your problem is right now. Can you summarise
it again ?
(And remind us of the versions of Java and tomcat please, it will save us a search through
the archive.)
What I suppose is that you now have this configuration, on one host for httpd
and tomcat :
browser <- HTTP/S -> httpd + mod_jk <- AJP -> tomcat AJP Connector
|
webapps
|
your webapp
|- files (HTML, JSP)
|- WEB-INF
|- private files
(Note in the above, that the protocol between mod_jk and tomcat is AJP, not HTTP/S. In
summary, it is a binary and somewhat optimised version of HTTP, which only mod_jk and the
AJP Connector in tomcat understand. But that should be transparent as far as tomcat
webapps are concerned).
You have a "workers.properties" file somewhere which tells the mod_jk module "where" the
tomcat instance is ("name", host/IP, port), and the AJP Connector in tomcat matches that
IP and port.
You also have a mod_jk setup (in the Apache config) that tells httpd which URLs should be
forwarded to which tomcat instance. These are the "JkMount" directives.
There are also logfiles, for both httpd and tomcat, which are generally helpful to find
out what happens.
I also seem to remember that initially, you had a problem getting httpd to load the mod_jk
module, but that now this is resolved, and the command "apache2ctl -M" shows the list of
loaded modules, including mod_jk.
So wat is the remaining issue ?
Note also :
In the information below, there is mention of a
> TOMCATS_BASE="/var/lib/tomcats/"
variable and directory. This is not something that I know. It may be new in recent
versions of tomcat, or it may be something which the CentOS package managers do.
(I also do not find it in the "RUNNING.txt" file of the tomcat 9 distribution, so I guess
that it is CentOS-specific.)
There may be more things like that, which may complicate a bit our efforts to help you,
because we do not necessarily have a CentOS system like yours at hand.
