Deploy with CentOS

Preparation Steps
Depending on the version of Rocket.Chat you want to install, check the release notes to see the supported engine versions for MongoDB and NodeJs, and install as recommended. 
MongoDB
Please refer to the official MongoDB documentation on installing MongoDB on CentOS. 
NodeJS
Follow the official guide to install NodeJS on CentOS. You can also use third-party tools like nvm or n.
Install Rocket.Chat on CentOS
Install the required dependency packages.
sudo yum install -y GraphicsMagick
Download and extract the latest release of Rocket.Chat.
curl -L https://releases.rocket.chat/latest/download -o /tmp/rocket.chat.tgz
Extract the Rocket.Chat server files.
tar -xzf /tmp/rocket.chat.tgz -C /tmp
cd /tmp/bundle/programs/server && npm install
Move the extracted files to the /opt directory.
sudo mv /tmp/bundle /opt/Rocket.Chat
This guide uses the /opt directory. However, you can choose your preferred directory.
Configure the Rocket.Chat service
Add the Rocket.Chat user and set the proper permissions on the Rocket.Chat folder.
sudo useradd -M rocketchat && sudo usermod -L rocketchat
sudo chown -R rocketchat:rocketchat /opt/Rocket.Chat
Create the Rocket.Chat service file.
cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service

EOFash
Using sudo and your preferred text editor, open the Rocket.Chat service file just created (/usr/lib/systemd/system/rocketchat.service). Change the ROOT_URL environmental variable to reflect the URL you want to access the server with.  Optionally, you can change the MONGO_URL, MONGO_OPLOG_URL and PORT variables.
MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01
MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01
ROOT_URL=http://your-host-name.com-as-accessed-from-internet:3000
PORT=3000
Set up the storage engine and replication for MongoDB.
sudo sed -i "s/^#  engine:/  engine: mmapv1/"  /etc/mongod.conf
sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf
The MongoDB replica set is mandatory for Rocket.Chat > 1.0.0.
Enable and start MongoDB with this command:
sudo systemctl enable mongod && sudo systemctl start mongod
mongo --eval "printjson(rs.initiate())"
Enable and start Rocket.Chat using this command:
sudo systemctl enable rocketchat && sudo systemctl start rocketchat
Configure your Rocket.Chat server
To access your Rocket.Chat workspace, open a web browser and navigate to the specified ROOT URL (http://your-host-name.com-as-accessed-from-internet:3000). Follow the configuration prompts to configure your workspace.​
