How to make Tomcat run on 443 instead of its default port 8080?
提问by Shivayan
We have a situation where we are required to run Tomcat and all its applications on port 443 instead of port 8080. Can anyone give a guidance on how this can be achieved? The process,its benefits and impacts.

Tomcat_home/conf/server.xml
search for
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
change 8080 to 443

Look in conf/server.xml, there will be a <Connector>element containing the attribute port="8080"- you can change that to be whatever you want.
查看 conf/server.xml，将有一个<Connector>包含该属性的元素port="8080"- 您可以将其更改为您想要的任何内容。
However, if someone's asked to to run it on 443, I'd guess what they actually want is https? In which case see http://tomcat.apache.org/tomcat-8.0-doc/ssl-howto.htmlfor how to set up ssl on tomcat.
但是，如果有人要求在 443 上运行它，我猜他们真正想要的是 https？在这种情况下，请参阅http://tomcat.apache.org/tomcat-8.0-doc/ssl-howto.html了解如何在 tomcat 上设置 ssl。

You can change Tomcat's port in the server.xml file (located in the conf directory). To change the port you have to modify the "port" attribute of the "connector" element.
您可以在 server.xml 文件（位于 conf 目录中）中更改 Tomcat 的端口。要更改端口，您必须修改“connector”元素的“port”属性。
If you want to run the Tomcat server on linux and you cannot run it as a privileged user you may use iptables to redirect the port 443 to 8080: iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8080
如果你想在 linux 上运行 Tomcat 服务器并且你不能以特权用户身份运行它，你可以使用 iptables 将端口 443 重定向到 8080： iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8080
