Disable SELinux

You need to disable SELinux in the /etc/selinux/config configuration file.

Open the /etc/selinux/config file using any text editor, replace the SELINUX=enforcing or SELINUX=permissive string with the SELINUX=disabled one and save the changes.

Reboot your server for the changes to take effect. Make sure that SELinux is disabled:

[root@test ~]# sestatus
SELinux status:                 disabled

Install ONLYOFFICE Docs

Execute the following command to install ONLYOFFICE Docs:

sudo docker run -i -t -d -p 80:80 --security-opt seccomp=unconfined --restart=always -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver

sudo docker run -i -t -d -p 80:80 --security-opt seccomp=unconfined --restart=always -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-ee

sudo docker run -i -t -d -p 80:80 --security-opt seccomp=unconfined --restart=always -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-de

The --security-opt seccomp=unconfined key is required to disable security profiles for the container. More details can be found here.

You can also use our custom security profile: kylin-seccomp7.json.

sudo docker run -i -t -d -p <PORT_NUMBER>:80 --security-opt seccomp=unconfined --restart=always -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver

sudo docker run -i -t -d -p <PORT_NUMBER>:80 --security-opt seccomp=unconfined --restart=always -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-ee

sudo docker run -i -t -d -p <PORT_NUMBER>:80 --security-opt seccomp=unconfined --restart=always -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-de

This will install ONLYOFFICE Docs and all the dependencies it needs (the list of what is being done by the script can be found here).

Add a firewall exception

You also need to add an exception to the firewalld.service service:

sudo firewall-cmd --zone=public --add-port=80/tcp --permanent
sudo firewall-cmd --reload

Once the configuration is finished, you can enter http://localhost in your browser address bar to open the ONLYOFFICE Docs welcome page where you will find further instructions on how to enable document examples or integrate online editors into your web application using the provided API.

All the data are stored in the specially-designated directories, data volumes, at the following location:

• /var/log/onlyoffice for ONLYOFFICE Docs logs
• /var/www/onlyoffice/Data for certificates
• /var/lib/onlyoffice for file cache
• /var/lib/postgresql for database

To get access to your data located outside the container, you need to mount the volumes. It can be done by specifying the -v option in the docker run command.

sudo docker run -i -t -d -p 80:80 --security-opt seccomp=unconfined --restart=always \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver

sudo docker run -i -t -d -p 80:80 --security-opt seccomp=unconfined --restart=always \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-ee

sudo docker run -i -t -d -p 80:80 --security-opt seccomp=unconfined --restart=always \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-de

Normally, you do not need to store container data because the container operation does not depend on its state. Saving data will be useful:

• for easy access to container data, such as logs;
• to remove the limit on the size of the data inside the container;
• when using services launched outside the container such as PostgreSQL, Redis, RabbitMQ.

sudo docker run -i -t -d -p 443:443 --security-opt seccomp=unconfined --restart=always \
-v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver

sudo docker run -i -t -d -p 443:443 --security-opt seccomp=unconfined --restart=always \
-v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-ee

sudo docker run -i -t -d -p 443:443 --security-opt seccomp=unconfined --restart=always \
-v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-de

Access to the onlyoffice application can be secured using SSL so as to prevent unauthorized access. While a CA certified SSL certificate allows for verification of trust via the CA, self signed certificates can also provide an equal level of trust verification as long as each client takes some additional steps to verify the identity of your website. Below the instructions on achieving this are provided.

To secure the application via SSL basically two things are needed:

• Private key (.key)
• SSL certificate (.crt)

So you need to create and install the following files:

/app/onlyoffice/DocumentServer/data/certs/onlyoffice.key
/app/onlyoffice/DocumentServer/data/certs/onlyoffice.crt

When using CA certified certificates (e.g Let's Encrypt), these files are provided to you by the CA. If you are using self-signed certificates, you need to generate these files yourself.

Switching ONLYOFFICE Docs to HTTPS using certbot

The easiest way to switch ONLYOFFICE Docs to HTTPS is to automatically get Let's Encrypt SSL Certificates using certbot.

Run the ONLYOFFICE Docs Docker container specifying ports 80 and 443 and setting your own values for the variables:

sudo docker run -i -t -d -p 80:80 -p 443:443 --security-opt seccomp=unconfined --restart=always \
    -e LETS_ENCRYPT_DOMAIN=yourdomain.com -e LETS_ENCRYPT_MAIL=email@example.com -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver

sudo docker run -i -t -d -p 80:80 -p 443:443 --security-opt seccomp=unconfined --restart=always \
    -e LETS_ENCRYPT_DOMAIN=yourdomain.com -e LETS_ENCRYPT_MAIL=email@example.com -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-ee

sudo docker run -i -t -d -p 80:80 -p 443:443 --security-opt seccomp=unconfined --restart=always \
    -e LETS_ENCRYPT_DOMAIN=yourdomain.com -e LETS_ENCRYPT_MAIL=email@example.com -e JWT_SECRET=my_jwt_secret onlyoffice/documentserver-de

Where:

• LETS_ENCRYPT_DOMAIN - a domain name to use for the certificate.
• LETS_ENCRYPT_MAIL - an email used for registration and recovery contact.

The letsencrypt.org CA-signed certificate will be automatically generated and installed to your server. Now your ONLYOFFICE Docs should be available at the https://yourdomain.com address.

Generation of self signed certificates

Generation of self-signed SSL certificates involves a simple 3 step procedure

STEP 1: Create the server private key

openssl genrsa -out onlyoffice.key 2048

STEP 2: Create the certificate signing request (CSR)

openssl req -new -key onlyoffice.key -out onlyoffice.csr

STEP 3: Sign the certificate using the private key and CSR

openssl x509 -req -days 365 -in onlyoffice.csr -signkey onlyoffice.key -out onlyoffice.crt

You have now generated an SSL certificate that's valid for 365 days.

Strengthening the server security

This section provides you with instructions to strengthen your server security.

To achieve this you need to generate stronger DHE parameters.

openssl dhparam -out dhparam.pem 2048

Installation of the SSL certificates

Out of the four files generated above, you need to install the onlyoffice.key, onlyoffice.crt and dhparam.pem files at the onlyoffice server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).

The default path that the onlyoffice application is configured to look for the SSL certificates is at /var/www/onlyoffice/Data/certs, this can however be changed using the SSL_KEY_PATH, SSL_CERTIFICATE_PATH and SSL_DHPARAM_PATH configuration options.

The /var/www/onlyoffice/Data/ path is the path of the data store, which means that you have to create a folder named certs inside /app/onlyoffice/DocumentServer/data/ and copy the files into it and as a measure of security you will update the permission on the onlyoffice.key file to only be readable by the owner.

mkdir -p /app/onlyoffice/DocumentServer/data/certs
cp onlyoffice.key /app/onlyoffice/DocumentServer/data/certs/
cp onlyoffice.crt /app/onlyoffice/DocumentServer/data/certs/
cp dhparam.pem /app/onlyoffice/DocumentServer/data/certs/
chmod 400 /app/onlyoffice/DocumentServer/data/certs/onlyoffice.key

And restart Docker container:

sudo docker restart {{DOCUMENT_SERVER_ID}}

You are now just one step away from having our application secured.
