## Overview
ONLYOFFICE Document Server is an online office suite comprising viewers and editors for texts, spreadsheets and presentations, fully compatible with Office Open XML formats: .docx, .xlsx, .pptx and enabling collaborative editing in real time.
## Functionality ##
* ONLYOFFICE Document Editor
* ONLYOFFICE Spreadsheet Editor
* ONLYOFFICE Presentation Editor
* ONLYOFFICE Documents application for iOS
* Collaborative editing
* Hieroglyph support
* Support for all the popular formats: DOC, DOCX, TXT, ODT, RTF, ODP, EPUB, ODS, XLS, XLSX, CSV, PPTX, HTML
Integrating it with ONLYOFFICE Community Server you will be able to:
* view and edit files stored on Drive, Box, Dropbox, OneDrive, OwnCloud connected to ONLYOFFICE;
* share files;
* embed documents on a website;
* manage access rights to documents.
## Recommended System Requirements
* **RAM**: 4 GB or more
* **CPU**: dual-core 2 GHz or higher
* **Swap file**: at least 2 GB
* **HDD**: at least 2 GB of free space
* **Distributive**: 64-bit Red Hat, CentOS or other compatible distributive with kernel version 3.8 or later, 64-bit Debian, Ubuntu or other compatible distributive with kernel version 3.8 or later
sudo docker run -i -t -d -p 80:80 onlyoffice/documentserver
Use this command if you wish to install ONLYOFFICE Document Server separately. To install ONLYOFFICE Document Server integrated with Community and Mail Servers, refer to the corresponding instructions below.
All the data are stored in the specially-designated directories, **data volumes**, at the following location:
* **/var/log/onlyoffice** for ONLYOFFICE Document Server logs
* **/var/www/onlyoffice/Data** for certificates
To get access to your data from outside the container, you need to mount the volumes. It can be done by specifying the '-v' option in the docker run command.
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, a 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:
When using CA certified certificates, these files are provided to you by the CA. When using self-signed certificates you need to generate these files yourself. Skip the following section if you are have CA certified SSL certificates.
#### Generation of Self Signed Certificates
Generation of self-signed SSL certificates involves a simple 3 step procedure.
**STEP 1**: Create the server private key
```bash
openssl genrsa -out onlyoffice.key 2048
```
**STEP 2**: Create the certificate signing request (CSR)
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](https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html).
To achieve this you need to generate stronger DHE parameters.
```bash
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.
You are now just one step away from having our application secured.
#### Available Configuration Parameters
*Please refer the docker run command options for the `--env-file` flag where you can specify all required environment variables in a single file. This will save you from writing a potentially long docker run command.*
Below is the complete list of parameters that can be set using environment variables.
- **ONLYOFFICE_HTTPS_HSTS_ENABLED**: Advanced configuration option for turning off the HSTS configuration. Applicable only when SSL is in use. Defaults to `true`.
- **ONLYOFFICE_HTTPS_HSTS_MAXAGE**: Advanced configuration option for setting the HSTS max-age in the onlyoffice nginx vHost configuration. Applicable only when SSL is in use. Defaults to `31536000`.
- **SSL_CERTIFICATE_PATH**: The path to the SSL certificate to use. Defaults to `/var/www/onlyoffice/Data/certs/onlyoffice.crt`.
- **SSL_KEY_PATH**: The path to the SSL certificate's private key. Defaults to `/var/www/onlyoffice/Data/certs/onlyoffice.key`.
- **SSL_DHPARAM_PATH**: The path to the Diffie-Hellman parameter. Defaults to `/var/www/onlyoffice/Data/certs/dhparam.pem`.
- **SSL_VERIFY_CLIENT**: Enable verification of client certificates using the `CA_CERTIFICATES_PATH` file. Defaults to `false`
## Installing ONLYOFFICE Document Server integrated with Community and Mail Servers
ONLYOFFICE Document Server is a part of ONLYOFFICE Community Edition that comprises also Community Server and Mail Server. To install them, follow these easy steps:
**STEP 1**: Create the 'onlyoffice' network.
```bash
docker network create --driver bridge onlyoffice
```
Than launch containers on it using the 'docker run --net onlyoffice' option:
Alternatively, you can use an automatic installation script to install the whole ONLYOFFICE Community Edition at once. For the mail server correct work you need to specify its hostname 'yourdomain.com'.
**STEP 1**: Download the Community Edition Docker script file
Or, use [docker-compose](https://docs.docker.com/compose/install "docker-compose"). For the mail server correct work you need to specify its hostname 'yourdomain.com'. Assuming you have docker-compose installed, execute the following command:
As a relatively new project Docker is being worked on and actively developed by its community. So it's recommended to use the latest version of Docker, because the issues that you encounter might have already been fixed with a newer Docker release.
The known Docker issue with ONLYOFFICE Document Server with rpm-based distributives is that sometimes the processes fail to start inside Docker container. Fedora and RHEL/CentOS users should try disabling selinux with setenforce 0. If it fixes the issue then you can either stick with SELinux disabled which is not recommended by RedHat, or switch to using Ubuntu.
ONLYOFFICE installation requires the presence of mono (tested for version 3.12.1 or [older](http://www.mono-project.com/docs/getting-started/install/linux/#accessing-older-releases "older")) that may cause problems for some Linux kernel versions. The full list of supported kernel versions is available [here](http://onlyo.co/1PABPEI "here").
