Dependencies for OnlyOffice document server are Nginx webserver, PostgreSQL database server, Node.js, Redis Server, and RabbitMQ server.

sudo apt install postgresql

Both the username and password are required to be 'onlyoffice'

Create Only Office database within PostgreSQL (Not MySQL):

sudo -i -u postgres psql -c "CREATE DATABASE onlyoffice;"

Create the OnlyOffice user.

sudo -i -u postgres psql -c "CREATE USER onlyoffice WITH password 'onlyoffice';"

Grant Permissions for the user on the OnlyOffice database:

sudo -i -u postgres psql -c "GRANT ALL privileges ON DATABASE onlyoffice TO onlyoffice;"

OnlyOffice document server requires nodejs version 8.12.0+, but the version in Ubuntu repository is outdated, so we will need to install the latest LTS version (12.13.1) of Node.js from upstream repository.

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

Install Node.js.

sudo apt install nodejs -y

Check Node.js version.

node -v

Sample output:

v12.18.0

Install Redis server and Rabbitmq

sudo apt install redis-server rabbitmq-server

Check their status.

systemctl status redis-server

systemctl status rabbitmq-server

Status should show these are active (running). If rabbitmq-server failed to start, that’s mostly because of low memory on the machine or invalid hostname. Redis server listens on 127.0.0.1:6379. RabbitMQ listens on 0.0.0.0:25672 and 0.0.0.0:4369

Add OnlyOffice repository with the following command.

echo "deb http://download.onlyoffice.com/repo/debian squeeze main" | sudo tee /etc/apt/sources.list.d/onlyoffice.list

Import OnlyOffice public key.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CB2DE8E5 

Update local package index and install OnlyOffice document server. Note that the onlyoffice-documentserver package will install nginx-extras as a dependency, so if an Apache web server is running, you need to stop it first.

sudo apt update

sudo apt install onlyoffice-documentserver

During the installation process, you will be asked to enter PostgreSQL password for onlyoffice. Enter the password:

onlyoffice

A Nginx server block will be installed as /etc/nginx/conf.d/ds.conf. (It’s actually a symbolic link to /etc/onlyoffice/documentserver/nginx/ds.conf.) The OnlyOffice document server is a nodejs web application and Nginx acts as the reverse proxy. /var/www/onlyoffice/documentserver/ is the web root directory.

Once the installation is finished, enter your server’s public IP address in web browser, you should see “Document Server is running”
