How change domain in jira

[SIGERI]

Hello,

I'm new to JIRA,
what porceso I must get to change the URL of my jira and also where you must make the change (I have two environments in linux and windows), these days my company will change domain for example: oranje.com:8080 to apple .com: 8080

I've been investigating the changes and they indicate that it should be changed in the URL URL of the site. so I wanted to know if I was sophisticated with that change.

for another we want to know if it is feasible to hide the port that shows as 8080 in the URL

finally I have a query.
as I indicated in the beginning I have two chiras for example as the following urls:

http://jira1.com:8080
http://jira2.com:8080

if I can configure the urls in the following way considering the ports are hidden:

http://jira1.com/jira6/
http://jira1.com/jira7/

also if it is feasible to put a single security certificate to that url.

Regards,
SIGERI

You need to run a proxy web server to do that.  A proxy can present many <server>/service:port  combinations as though it is a single site. 

I tend to use Apache to do it with "proxypass/proxypassreverse" pairs, but other web servers can do it just as well (or better!).  Nginx, Lighttpd, IIS and so-on.

A snippet of my Apache configuration here says:

    ProxyPass /crowd http://192.168.1.33:8095/crowd
    ProxyPassReverse /crowd http://192.168.1.33:8095/crowd
    ProxyPass /jira http://192.168.1.144:8081/jira
    ProxyPassReverse /jira http://192.168.1.144:8081/jira

You should be able to see from that that I am running Crowd and Jira from different servers on different port.  But when I go to my home page, I just have /crowd and /jira to go to.  No ports etc.  In this example, you could easily swap my Crowd and Jira for your Jira1 and Jira2
