Run TomCat on port 80?

[Dundonald]

How can I get TomCat to run on port 80? I'm not interested in having
apache serve static content, I just want Tomcat to serve everything.
So I'm not too interested in mod_jk to hook Apache up with tomcat.

Thanks

Since Java provides no mechanism for altering the OS user the JVM is
running as, running Tomcat on port 80 involves allowing Tomcat to run
as root. Apache gets around this by binding to 80 as root and then
dropping to a non-privileged account based on the contents of
httpd.conf.

Running Tomcat as root should give you pause, at the very least.

Yes it does if it means having to run as root. But that sucks!

If you're running Solaris 10, you can use a non-root
account by granting it the PRIV_NET_PRIVADDR privilege.
This allows processes running under that account to bind
low-numbered ports without allowing them to do other
rootly things. "man -s5 privileges" (if applicable).

Edit server.xml and change port 8080 to 80 ...

Not all OS's have "root" and not all OS's have the <port 1024 rule.

If you're using iptables you can create a rule to redirect port 80
traffic to port 8080.

Dundonald,

it is always the best to install apache und using tomcat via connector.
Alternatively you can use iptable.

I would assume that Tomcat has a configuration file where you can set
the port. I only use Resin, so I don't know for sure. you might do a
grep on all the config files for 8080 (I assume thats the default Tomcat
port).

Good Luck,
Daniel.

There are some cases where that is a good idea. But I would say that
there are also cases where it is just a completely unnecessary
complexity.
