Change url

[getzze]

Hi,
I installed Rocket.chat with the testing branch (6e94ffa).
I just had to comment line 147 mongo --eval "printjson(rs.initiate())" in scripts/install, but I managed to install it.

I also had another problem (introduced with the last commit I am afraid), I installed it in rocketchat.maindomain.tld with the path /, which resulted in an error 404 when opening https://rocketchat.maindomain.tld.
In the rocketchat.service files, ROOT_URL was indeed defined as ROOT_URL=https://rocketchat.maindomain.tld/:3000. Where I could find my server! But this url was not very practical so I needed to change it.
After changing it to ROOT_URL=https://rocketchat.maindomain.tld/, I was still not able to open rocket chat at this address.
Then I found this page explaining that ROOT_URL becomes stored in mongodb at the first connection, so you have to change it there also:
https://www.ryadel.com/en/rocket-chat-change-root_url-site-url-rocketchat/

The steps to change url:

> mongo
> use rocketchat
> db.rocketchat_settings.update({"_id" : "Site_Url"},{$set:{value:"<YOUR NEW URL>"}})

I thought it would be useful to implement the change_url script.

Thanks for the feedback. RocketChat should be working now.

The update to version 4.1.2 worked well, thanks!
But the change_url script is not working.
ROOT_URL is not changed in rocketchat.service and more importantly "Site_Url" is not changed in mongodb, as I described in my first message.
Maybe adding the following to the change_url script could work:

db_name=$(ynh_sanitize_dbid --db_name=$app)
new_url="https://${new_domain}${new_path}"
ynh_mongo_exec --database="$db_name" --command='db.rocketchat_settings.update({"_id" : "Site_Url"}, {$set: {value: "'${new_url}'"}});'
