Rocket.Chat in CentOS

STEP 1-  Install necessary dependency packages

  • Update package list and configure yum to install the official MongoDB packages with the following yum repository file:
     sudo yum -y check-update

cat << EOF | sudo tee -a /etc/yum.repos.d/mongodb-org-4.0.repo
[mongodb-org-4.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc
EOF


Configure Node.js to be installed via package manager:
      sudo yum install -y curl && curl -sL https://rpm.nodesource.com/setup_8.x | sudo bash -

Install build tools, MongoDB, nodejs and graphicsmagick:

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

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

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

sudo
npm install -g inherits n && sudo n 8.11.4


STEP 2- 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

Install (this guide uses /opt but feel free to choose a different directory):

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

      sudo mv /tmp/bundle /opt/Rocket.Chat


STEP 3- 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:

      sudo useradd -M rocketchat && sudo usermod -L rocketchat
      sudo chown -R rocketchat:rocketchat /opt/Rocket.Chat

cat << EOF |sudo tee -a /lib/systemd/system/rocketchat.service
[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=rocketchat
Environment=MONGO_URL=mongodb://localhost:27017/rocketchat?replicaSet=rs01 MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01 ROOT_URL=http://localhost:3000/ PORT=3000
[Install]
WantedBy=multi-user.target
EOF

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://your-host-name.com-as-accessed-from-internet:3000
PORT=3000

Setup storage engine and replication for MongoDB (mandatory for versions > 1), and enable and start MongoDB and Rocket.Chat:
     sudo sed -i "s/^#  engine:/  engine: mmapv1/"  /etc/mongod.conf
     sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf
     sudo systemctl enable mongod && sudo systemctl start mongod
     mongo --eval "printjson(rs.initiate())"
     sudo systemctl enable rocketchat && sudo systemctl start rocketchat


STEP 4- Configure your Rocket.Chat server

Open a web browser and access the configured ROOT_URL (http://your-host-name.com-as-accessed-from-internet:3000), follow the configuration steps to set an admin account and your organization and server info.
