Contrib: [1]John Crisp

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

However, due to dependencies a manual install will not work on SME

Version up to 0.61.2 will work with this contrib.

Later versions will need my newer smeserver-rocketchat-0.2.x contrib which uses docker.

smeserver-rocketchat contrib

Warning.png 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

Current version

3rd March 2018

Rocket RPM in my repo is 0.61.2

0.61.2 is likely to be the last version that can be installed direct to CentOS 6/ Koozali SME v9.x due to node module dependency requirements

I have tried to build 0.62.0 so far without success see this bug https://github.com/RocketChat/Rocket.Chat/issues/9943


Latest source is here:


Important.png Note:
Latest version is 0.61.2

This requires node 8.x and a prebuilt module which the RPM should install

I am currently looking at running Rocket 0.62 on docker in CentOS 6 which I do have working using the existing local Mongo DB

I will post a link to a new wiki page when I have it tested further and know what I am doing with Docker

Required repos

Add repos:

signal-event yum-modify
yum --enablerepo=nodejs8 install nodejs nodejs-devel

RocketChat 0.40+

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

Rocket.Chat v 60.0+ requires: node: v8.9.3 npm: v5.6.0

This can be installed from the node repo. The following is how to check and set up node versions manually - the rpm should sort this out for you.

Setup node versions:

Some of this is magic (to me!) and I still don't get the local and global stuff. Be careful with paths. See NPM Usage below for more.

The node rpm install node to /usr/bin but the npm 'n' module will install to /usr/local/bin

Check the version of node in /usr/bin

[root@test ~]# node -v

Install n version manager:

npm install -g n

Install specific node version (which will go in /usr/local/bin)

n 8.9.3

Install the LTS version

 n lts

List available versions

n ls

Install latest version of npm:

npm install -g npm

Install specific npm version:

npm install -g npm@5.6.0

Show the npm version

[root@test ~]# npm --version

Install required rpms

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

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

yum --enablerepo=reetp install smeserver-rocketchat

Don't post-upgrade yet.

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

Now we should be able to install rocketchat itself - it is better to specify a version here in case a newer version breaks anything:

yum --enablerepo=reetp install rocketchat-0.59.6

Check the progress:

tailf /var/log/rocketchat.log
System ➔ startup
|                  SERVER RUNNING                    |
|                                                    |
|       Version: 0.xx.x                              |
|  Process Port: 3000                                |
|      Site URL: http://rocketchat.local.net:3000    |
|         OpLog: Disabled                            |
|                                                    |

You should now be able to connect to your Rocket.Chat instance


Registering a new account

Because the SME mail server is fussy you may find it easier to force some settings in the Rocket.Chat DB before trying to register:

You can set your SMTP host as localhost or mail.yourdomain.com

use rocketchat
db.rocketchat_settings.update({"_id" : "SMTP_Host"}, {$set: {"value":"mail.yourdomain.com"}})
db.rocketchat_settings.update({"_id": "From_Email"}, {$set: {"value":"admin@yourdomain.com"}})

Restart Rocket.Chat to be sure:

service rocketchat restart

You should now be able to register a new account and get a confirmation email. Check /var/log/qpsmtpd/current for any errors.

If you have not set the From address you are likely to get:

Mail with no From header not accepted here


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

service rocketchat stop

Check /var/log/rocketchat.log

Try running main.js manually:

export PORT=3000
export MAIL_URL=smtp://localhost:25
export MONGO_URL=mongodb://localhost:27017/rocketchat
export ROOT_URL=http://my.smeserver.net/opt/Rocket.Chat
node main.js

SSL with Proxypass

Important.png 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 (see here for my contrib https://wiki.contribs.org/Letsencrypt)

We need some extra settings to enable SSL with ProxyPass.

Add the FWS repo:

db yum_repositories set fws repository \
BaseURL http://repo.firewall-services.com/centos/\$releasever \
EnableGroups no GPGCheck yes \
Name "Firewall Services" \
GPGKey http://repo.firewall-services.com/RPM-GPG-KEY \
Visible yes status disabled

Update the repos:

signal-event yum-modify

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 for the reverse proxy

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

It should look like this:

  Nameservers=internet (can be localhost)
  letsencryptSSLcert=enabled (with letsencrypt support)

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

config setprop rocketchat rootURL chat.mycompany.domain SSLProxy yes
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

You may find you need to clear your browser cache before it works correctly on https://chat.mycompany.local rather than http://chat.mycompany.local:3000

IF you have Letsencrypt support you can now set your main domain to SSL only:

db accounts setprop Primary SSL enabled
signal-event ibay-modify Primary


To upgrade rocketchat:

yum --enablerepo=reetp install rocketchat

To upgrade the rocketchat configurator:

yum --enablerepo=reetp install smeserver-rocketchat


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.

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

Mongod fails to start after reboot

Sometimes it appears that mongo fails to start after a reboot.

I believe that this may be caused due to rocketchat being run by the forever service which means that rocketchat tries to keep running as the server shuts down despite mongod being stopped. This leaves lock files and prevents mongod from restarting properly. I think I probably need to look at the shutdown/start order of scripts.

A simple cure is as follows:

/etc/rc.d/init.d/rh-mongodb26-mongod stop

Remove the following files if they exist:

rm /var/opt/rh/rh-mongodb26/lib/mongodb/mongod.lock
rm /var/opt/rh/rh-mongodb26/run/mongodb/mongod.pid

Restart the mongod service:

/etc/rc.d/init.d/rh-mongodb26-mongod start

Restart the rocketchat service:

service rocketchat restart

The following is simpler and appears to work:

service rocketchat stop
/etc/rc.d/init.d/rh-mongodb26-mongod restart
service rocketchat start

Mongo DB examples


Example using mongo itself:

use rocketchat

Show all collections in DB

show collections

Show all entries in a collection

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"}, {$set: {"value":"admin@yourdomain.com"}})
db.rocketchat_settings.update({"_id":"SMTP_Host"}, {$set: {"value":"mail.yourdomain.com"}})

Remove all entries in a collection (CAREFUL!!!!!!)




Some more mongo commands for reference


Directly check a specific user ID from bash:

mongo rocketchat --eval "db.users.find({'username':'usernamehere'}).forEach( function(u) { print(u._id + \" ; \" + u.username); } )"

Log into rocketchat database:

mongo rocketchat

Check out all the user IDs in the database:

db.users.find().forEach( function(u) { print(u._id + ";" + u.username); } ) 

Or just a specific user's ID:

db.users.find({'username':'usernamehere'}).forEach( function(u) { print(u._id + \" ; \" + u.username); } )

Replace specific user ID's password in the database:

db.users.update( {'_id': 'useridhere'}, {$set: {'services.password.bcrypt': 'bcryptedpasswordhere'}}, {multi:true} )

My only issue with above (only time I needed it for recovery purposes), was that I didn't know which tool to use to generate a bcrypted password. So in the hurry I copied the hash from one account I already knew (my own). If someone knows a good command for creating one directly in bash, I assume it would do.

There are bcrypt password generators online, and various libraries you can use

For listing out any passwords in the database I used:

 db.users.find().forEach( function(u) { print(u.services.password.bcrypt + " ; " + u.username); } ) 

If you have deactivated users it may fail so use this for individual accounts.

However, you can get it for an individual user with:

db.users.find({'username':'SomeUserName'}).forEach( function(u) { print(u.services.password.bcrypt + " ; " + u.username); } ) 

Set a user config item:

db.users.update( {'username': 'SomeUserName'}, {$set: {'settings.preferences.showMessageInMainThread': 'true'}} )

Find a single user:

db.getCollection('users').find( {'username':'SomeUserName'} )

Get limited information:

db.getCollection('users').find({}, {"username":1, "settings.preferences.showMessageInMainThread":1})

Database Backup

You can dump the tables to a directory of your choice:

mongodump --dumpDbUsersAndRoles -d rocketchat -o /root/rocketchatmongo

Database Restore

You can restore you database as follows:

mongorestore --restoreDbUsersAndRoles -d rocketchat -dir  /root/rocketchatmongo/rocketchat --quiet

Node usage

Use n, an extremely simple Node version manager that can be installed via npm (See http://stackoverflow.com/questions/7718313/how-to-change-to-an-older-version-of-node-js)

Say you want Node.js v0.10.x to build Atom.

npm install -g n   # Install n globally
n 0.10.33          # Install and use v0.10.33 local only


n                            # Output versions installed
n latest                     # Install or activate the latest node release
n stable                     # Install or activate the latest stable node release
n <version>                  # Install node <version>
n use <version> [args ...]   # Execute node <version> with [args ...]
n bin <version>              # Output bin path for <version>
n rm <version ...>           # Remove the given version(s)
n --latest                   # Output the latest node version available
n --stable                   # Output the latest stable node version available
n ls                         # Output the versions of node available

NPM Usage

To update your version of npm run the following

npm install -g npm

Or for a specific version:

npm install -g npm@3.10.9

DB settings

Typical standard setup:


Typical proxy subdomain setup:


Koozali SME v10

I am starting to look at running this under docker on v10

Some quick notes.

You will need

Docker https://wiki.contribs.org/Docker

Docker Compose (because it makes it easier to template) https://github.com/docker/compose/releases

Mongo (I prefer to run a full instance rather than a docker one) https://wiki.contribs.org/MongoDB

Make sure you add replicaset support in Mongo https://docs.rocket.chat/installation/manual-installation/centos

I'll add more later, and try and make a full contrib in due course

CentOS 7 notes

Setup storage engine and replication for MongoDB (mandatory for versions > 1), and enable and start MongoDB and Rocket.Chat:

They still recommend mmapv1 but it is probably better to stick with the default WiredTiger. Here's how to change if required:

sed -i "s/^#  engine:/  engine: mmapv1/"  /etc/mongod.conf

You MUST initialise a replicaset so we must add this to the conf file:

sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf

Start Mongo

systemctl enable mongod && sudo systemctl start mongod

Initiate the set:

mongo --eval "printjson(rs.initiate())"
