Configure Node.js to be installed via package manager:

yum install -y curl && curl -sL https://rpm.nodesource.com/setup_12.x | bash -

Install build tools, MongoDB, nodejs and graphicsmagick:

yum install -y gcc-c++ make mongodb-org nodejs

yum install -y epel-release && yum install -y GraphicsMagick

Using npm install inherits and n, and the node version required by Rocket.Chat:
npm install -g inherits n && n 12.18.4

Install Rocket.Chat

Download the latest Rocket.Chat version:

curl -L https://releases.rocket.chat/latest/download -o /tmp/rocket.chat.tgz

tar -xzf /tmp/rocket.chat.tgz -C /tmp

cd /tmp/bundle/programs/server && npm install

mv /tmp/bundle /opt/Rocket.Chat

Configure the Rocket.Chat service

Add the rocketchat user, set the right permissions on the Rocket.Chat folder and create the Rocket.Chat service file:

useradd -M rocketchat && usermod -L rocketchat

chown -R rocketchat:rocketchat /opt/Rocket.Chat

cat << EOF | tee -a /lib/systemd/system/rocketchat.service

Open the Rocket.Chat service file just created (/usr/lib/systemd/system/rocketchat.service) using sudo and your favourite text editor, and change the ROOT_URL environmental variable to reflect the URL you want to use for accessing the server (optionally change MONGO_URL, MONGO_OPLOG_URL and PORT):

MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01

MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01

ROOT_URL=http://chat.ijguo.com:3000

PORT=3000

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

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

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

systemctl enable mongod && systemctl start mongod

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

systemctl enable rocketchat && systemctl start rocketchat
