Rocket Chat:Contrib

Contrib: John Crisp

	Note:
	Please note that there is also a howto on installing Rocket.Chat manually here

smeserver-rocketchat contrib

	Work in Progress:
	This page is a Work in Progress. The contents off this page may be in flux, please have a look at this page history the to see list of changes.

This contrib aims to reduce some of the setup for rocketchat and add some flexibility with settings

	Note:
	This will ONLY work up to Rocket Chat version 0.39 as they changed the required node version after that. I am working on an update to the contrib - see the end for notes

Add repos:

• epel
• Centos-sclo-rh
• reetp

yum install rh-python34-python rh-mongodb26-mongodb rh-mongodb26-mongodb-server nodejs010 GraphicsMagick --enablerepo=centos-sclo-rh,epel

scl enable nodejs010 bash
npm install -g inherits
npm install -g n
n 0.10.40
exit

	Note:
	Please be careful to only install JUST the required packages in my repo. There are various testing packages in there that will BREAK YOUR SYSTEM !

You should now be able to install the rocketchat bundle with:

yum --enablerepo=reetp install rocketchat

This may take a while on first install as it installs the npm modules for the first time.

Now you should be able to install the rocketchat contrib:

yum --enablerepo=reetp install smeserver-rocketchat

db configuration setprop rocketchat status enabled

signal-event post-upgrade;signal-event reboot

DB settings

rocketchat=service
   TCPPort=3000
   access=public
   mailPort=25
   mailURL=localhost
   status=enabled

rh-mongodb26-mongod=service
   TCPPort=27017
   access=private
   mongoURL=localhost
   status=enabled

BEFORE we login for the first time we need to set up mail settings correctly:

From bash:

mongo rocketchat --eval 'db.rocketchat_settings.update({"_id" : "SMTP_Host"}, {$set: {"value":"localhost"}});'
mongo rocketchat --eval 'db.rocketchat_settings.update({"_id" : "From_Email"}, {$set: {"value":"admin@yourdomain.com"}});'

We can check the individual values set like this:

mongo rocketchat --eval 'db.rocketchat_settings.find({"_id":"From_Email"}, {_id:0, value:1}).shellPrint();'
mongo rocketchat --eval 'db.rocketchat_settings.find({"_id":"SMTP_Host"}, {_id:0, value: 1}).shellPrint();'

All values per _id:

mongo rocketchat --eval 'db.rocketchat_settings.find({"_id" : "SMTP_Host"}).shellPrint();'
mongo rocketchat --eval 'db.rocketchat_settings.find({"_id" : "From_Email"}).shellPrint();'

Now restart rocketchat to reread the DB settings:

service rocketchat restart

Login at http://yourdomain:3000

It will first get you to create an admin user.

If you have an issue with no email sent/received then login using the email address and password you just set

Updates

If there is an update to Rocket.Chat I will add to my repo. You should just be able to run:

yum --enablerepo=reetp install rocketchat

You can also update the smeserver-rocketchat contrib in the same way

yum --enablerepo=reetp install smeserver-rocketchat

SSL

	Note:
	This is still experimental and there may be issues with SSL only for the Primary iBay and Letsencrypt. You will need a minimum version of smeserver-rocketchat-0.1-5

	Note:
	I've realised I need to re-hack the web templates for this but still trying to work it out - please ask in the forums and I can give you some tips to get it working

It is recommended to add Letsencrypt support as detailed below.

We need some extra settings to enable SSL with ProxyPass.

First install proxy pass rpm:

Add the FWS repo

• Fws

yum --enablerepo=fws install mod_proxy_wstunnel

Regenerate httpd.conf

signal-event remoteaccess-update

Now we need to setup our subdomain

db domains set chat.mycompany.local domain Description RocketChat Nameservers internet \
TemplatePath ProxyPassVirtualRocketchat ProxyPassTarget http://localhost:3000/

It should look like this:

chat.mycompany.local=domain
   Nameservers=internet
   ProxyPassTarget=http://127.0.0.1:3000/
   TemplatePath=ProxyPassVirtualRocketchat

We need to set Rocket.Chat to listen on localhost now:

config setprop rocketchat rootURL localhost
signal-event remoteaccess-update
service rocketchat restart

If you can now successfully get to Rocketchat on your subdomain https://chat.mycompany.local you can disable default access on port 3000:

config setprop rocketchat access private
signal-event remoteaccess-update

Letsencrypt support

	Note:
	26 Aug 2016 - This should now work for a subdomain

You can add letsencrypt should you wish - please see https://wiki.contribs.org/Letsencrypt

You will need to add the domain key as follows, and add your letsencrypt certificates as per the wiki page:

db domains setprop chat.mycompany.local letsencryptSSLcert enabled

Note that smeserver-rocketchat adds redirect on port 80 for the letsencrypt directory .well-known/acme-challenge

You should be able to reach:

http://chat.mycompany.local/.well-known/acme-challenge/ 

This should redirect to:

https://chat.mycompany.local/.well-known/acme-challenge/

Anything else going to chat.mycompany.local should get to Rocket.Chat

Bugs

Look for bugs :-) As the contrib is not in CVS please report them in the forum and I will try and keep an eye out.

You ay get an error on install of the rocketchat rpm as follows:

npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

This is due to the installed version of npm/node from SCL. Rocket.Chat should till work

Mongo DB examples

Example using mongo itself:

mongo

use rocketchat

db.rocketchat_settings.find({"_id" : "SMTP_Host"})
db.rocketchat_settings.find({"_id" : "From_Email"})

db.rocketchat_settings.findOne({_id : "From_Email"}, {_id:0, value: 1})
db.rocketchat_settings.findOne({_id : "SMTP_Host"}, {_id:0, value: 1})

db.rocketchat_settings.update({"_id" : "From_Email"}, {$set: {"value":"admin@reetspetit.info"}})
db.rocketchat_settings.update({"_id" : "SMTP_Host"}, {$set: {"value":"mail.reetspetit.info"}})

Rocketchat 0.40+

From Rocketchat 0.40 onwards you require a higher version of node than the one in the EPEL repos.

Setup

Add the following repos:

/sbin/e-smith/db yum_repositories set epel repository \
Name 'Epel - EL6' \
BaseURL 'http://download.fedoraproject.org/pub/epel/6/$basearch' \

EnableGroups no \
GPGCheck yes \
GPGKey http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL \
Exclude perl-Razor-Agent \
Visible no \
status disabled

/sbin/e-smith/db yum_repositories set reetp repository \
BaseURL http://www.reetspetit.com/smeserver/\$releasever \

signal-event yum-modify

yum --enablerepo=nodejs install nodejs nodejs-devel

yum --enablerepo=centos-sclo-rh,epel install scl-utils rh-python34-python rh-mongodb26-mongodb rh-mongodb26-mongodb-server \
GraphicsMagick 

You should be able to install the smeserver-rocketchat RPM now

yum --enablerepo=reetp install smeserver-rocketchat

config set rocketchat service TCPPort 3000 mailPort 25 mailURL localhost access public status enabled
config set rh-mongodb26-mongod service TCPPort 27017 mongoURL localhost access private status enabled

signal-event post-upgrade;signal-event reboot

+--------------------------------------------------+

If you have issues make sure you stop the rocket chat service

service rocketchat stop

Check your node versions:

[root@test Rocket.Chat]# node -v

v4.5.0

[root@test Rocket.Chat]# npm -v

3.10.8

Modify with

n 0.4.6

Try running main.js

/opt/Rocket.Chat
node main.js

Manual config of templates

expand-template /etc/rc.d/init.d/rocketchat
expand-template /etc/profile.d/scls-rh-mongodb26.sh
expand-template /etc/profile.d/scls-rh-python34.sh
expand-template /etc/profile.d/scls-rh-java-common.sh
expand-template /etc/opt/rh/rh-mongodb26/mongod.conf

/etc/rc.d/init.d/rocketchat start
/etc/rc.d/init.d/rh-mongodb26-mongos start

Proxy Pass

The contrib will sort out the templates. You just need some settings as follows:

[root@test e-smith]# db domains show
chat.reetspetit.info=domain
   Description=RocketChat
   Nameservers=internet
   ProxyPassTarget=http://127.0.0.1:3000/
   TemplatePath=ProxyPassVirtualRocketchat
   letsencryptSSLcert=enabled

SSL

	Note:
	This is still experimental and there may be issues with SSL only for the Primary iBay and Letsencrypt. You will need a minimum version of smeserver-rocketchat-0.1-5

It is recommended to add Letsencrypt support as detailed below.

We need some extra settings to enable SSL with ProxyPass.

First install proxy pass rpm:

yum --enablerepo=fws install mod_proxy_wstunnel

Regenerate httpd.conf

signal-event remoteaccess-update

Now we need to setup our subdomain

db domains set chat.mycompany.local domain Description RocketChat Nameservers internet \
TemplatePath ProxyPassVirtualRocketchat ProxyPassTarget http://localhost:3000/

It should look like this:

chat.mycompany.local=domain

service rocketchat restart

If you can now successfully get to Rocketchat on your subdomain https://chat.mycompany.local you can disable default access on port 3000:

config setprop rocketchat access private
signal-event remoteaccess-update
