Rocket.Chat installation in CentOS 7

Valentine

Rocket.Chat is a Web Chat Server, developed in JavaScript, using the Meteor fullstack framework as a Slack alternative

It is a great solution for communities and companies wanting to privately host their own chat service or for developers looking forward to building and evolve their own chat platforms.

The tutorial was prepared with our "CentOS 7" template and is meant to work on our self-managed virtual private servers.

0. Preliminary requirements:
"CentOS 7" template installed on the server;
Removed Apache (yum remove httpd -y).

1. Installation of dependencies

The first thing we need to do is to install epel repository. For this enter command:

yum install epel-release nano -y && yum update -y

Now we need to add MongoDB repository. Create new file "mongodb.repo" and paste repository info in it:

nano /etc/yum.repos.d/mongodb-org-4.00.re

[mongodb-org-4.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

We are now ready to install all the necessary dependencies:
yum install -y nodejs curl GraphicsMagick npm mongodb-org-server mongodb-org gcc-c++

npm install -g inherits n

n 4.8.4

2. Rocket.Chat installation

The following commands will download and install the latest Rocket.Chat instance:

cd /opt

curl -L https://releases.rocket.chat/stable -o rocket.chat.tar

tar zxvf rocket.chat.tgz

mv bundle Rocket.Chat

cd Rocket.Chat/programs/server

npm install

3. Creating auto start

We don't want for server restart to intervene with our Rocket.Chat accessibility. For that we have to enable Rocket.Chat auto start. Just create service file:

nano /usr/lib/systemd/system/rocketchat.service

With a text:

[Unit]
Description=The Rocket.Chat server
After=network.target remote-fs.target nss-lookup.target nginx.target mongod.target
[Service]
ExecStart=/usr/local/bin/node /opt/Rocket.Chat/main.js
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=rocketchat
User=root
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat ROOT_URL=http://server-hostname/ PORT=80
[Install]
WantedBy=multi-user.target

NOTE: do not forget to change server-hostname with your server hostname.

And enable this service by running:

systemctl enable rocketchat.service

4. Launching Rocket.Chat

We are finally ready to launch our Rocket:

systemctl start rocketchat.service

Open http://server-hostname with your favorite browser and register a new account:

I did all steps and the Rocketchat service is active (running). I also changed the hostname but on my domain I only see the Apache test website. Any ideas?

Make sure you have removed Apache (step 0). Also in step 3 server-hostname should be the domain you are going to use.

Yes, I overlooked step 0.

Thank you for your very fast response!

Hey Valentine.

Can you explain how to add TLS (using Certbot / Let's Encrypt) for this tutorial?
