Below a very simple way to install the free alternative to Slack or rocket.chat system Centos7

Installation is simple and make it in a few minutes.

For starters make system updates, and run packages EPEL

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

We create a repository MongoDB

nano /etc/yum.repos.d/mongodb.repo

The content:

[mongodb]
name=MongoDB Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
gpgcheck=0
enabled=1

Then we make the necessary installation packages:

yum install -y nodejs curl GraphicsMagick npm mongodb-org-server mongodb-org gcc-c++

The next step is to install above sea level

npm install -g inherits n

By default, the altitude version is installed 2.9. Rocket.chat version needs a minimum 8. We make the installation command:

n 8.9.3

Installation Rocket.Chat

Go to the / opt directory

cd /opt

Grab the latest version available rocket.chat and unpack it.

curl -L https://releases.rocket.chat/latest/download -o rocket.chat.tar.gz

tar zxvf rocket.chat.tar.gz

We move files and make installation rocket.chat

mv bundle Rocket.Chat

cd Rocket.Chat/programs/server

npm install

cd ../..

The next step is to configure mongodb spend command as below:

export PORT=3000
export ROOT_URL=http://NASZA DOMENA BĄDŹ ADRES IP:3000/
export MONGO_URL=mongodb://localhost:27017/rocketchat

introduce changes:

chkconfig mongod on

We start command mongodb:

systemctl start mongod

Now we can go to run command rocket.chat:

node main.js

If everything is ok in the console log we should see similar to the one below:

➔ System ➔ startup
➔ +---------------------------------------------------+
➔ |                   SERVER RUNNING                  |
➔ +---------------------------------------------------+
➔ |                                                   |
➔ |  Rocket.Chat Version: 0.66.0                      |
➔ |       NodeJS Version: 8.9.3 - x64                 |
➔ |             Platform: linux                       |
➔ |         Process Port: 3000                        |
➔ |             Site URL: http://OUR IP ADDRESS:3000/  |
➔ |     ReplicaSet OpLog: Disabled                    |
➔ |          Commit Hash: 5aa08cba32                  |
➔ |        Commit Branch: HEAD                        |
➔ |                                                   |
➔ +---------------------------------------------------+

Now, by using the browser: http://OUR IP ADDRESS:3000/ you should see the first registration form you make.

If the page is not displayed verify that the firewall does not block port us:3000

Clean the CentOS firewall system can be the following commands:

iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT

Virtually all, Configuration is done from the browser and does not need to be specially somehow describe the rocket.chat is in Polish.

We will create a script auto-start in the event as if there was a server restart.

create a file:

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

The content:

  [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://NASZA DOMENA BĄDŹ ADRES IP:3000/ PORT=3000
  [Install]
  WantedBy=multi-user.target

We make its launch:

systemctl enable rocketchat.service
systemctl start rocketchat.service

That's all.
