OpenMediaVault Install NextCloud

I. Create the configuration folder required by nextcloud

nextcloud shared folder

Access Rights Management -> Shared Folders, create a folder named nextcloud.

After OMV creates the shared folder, it will map the shared folder to a file path of /sharedfolders, so you have two paths to access the shared folder you just created, one is the path to your disk One is a path under the public /sharedfolders. The operations under both paths are valid. You can choose one at will.
For example, the shared folder of nextcloud that I just created. If I want to find it, I can find it in both paths.

Subfolders required by nextcloud

db: Database for persistent data that nextcloud depends on
html: Nextcloud resource configuration folder
data: personal sync file for nextcloud (the data of your network disk will be stored here later)
onlyoffice: log and data folders for onlyoffice office suite

II. Database Preparation

By default, NextCloud uses a SQLite database for data storage, which is only suitable for testing and lightweight single-user settings without client synchronization. When there are multiple users, multiple devices, and large amounts of data, SQLite is not suitable. NextCloud supports multiple databases such as MySQL, MariaDB, Oracle 11g, and PostgreSQL. And it is recommended to use MySQL / MariaDB. So for the sake of once and for all, use MySQL instead. MariaDB is a branch of the MySQL source code. Here MariaDB is used as the database support.

Install mariadb
Here we install mariadb using docker. Open your terminal and copy the following command to create the mariadb container.

docker run -d --name db_nextcloud \
    -p 3307:3306 \
    -e PUID=1000 \
    -e PGID=100 \
    -e MYSQL_ROOT_PASSWORD=123456 \
    -e MYSQL_DATABASE=nextcloud \
    -e MYSQL_USER=nextcloud \
    -e MYSQL_PASSWORD=123456 \
    --restart=unless-stopped \
    -v /sharedfolders/nextcloud/db:/var/lib/mysql \
     mariadb

Explanation of command parameters
(for specific parameter definitions, please see mariadb official images site ):

-p 3307:3306: Open port of the container service, the former is the port of the host machine, the latter is the port of the service inside the container

-e PUID, -e PGID: the permission set id of the user running the container

-e MYSQL_ROOT_PASSWORD: The password of the database root user

-e MYSQL_DATABASE=nextcloud: Create a database named nextcloud

-e MYSQL_USER: Create a user named nextcloud

-e MYSQL_PASSWORD: The password of the user named nextcloud

--restart=unless-stopped: restart the container when the container is stopped

-v: data volume binding The former is the address of the host machine, the latter is the location of the container machine

For example: -v /sharedfolders/nextcloud/db:/var/lib/mysql Hang the contents of the container /var/lib/mysql to the location of the host /sharedfolders/nextcloud/db

Following is the log I run

qinkangdeid@omv:~$ docker run -d --name db_nextcloud \
>     -p 3307:3306 \
>     -e PUID=1000 \
>     -e PGID=100 \
>     -e MYSQL_ROOT_PASSWORD=123456 \
>     -e MYSQL_DATABASE=nextcloud \
>     -e MYSQL_USER=nextcloud \
>     -e MYSQL_PASSWORD=123456 \
>     --restart=unless-stopped \
>     -v /sharedfolders/nextcloud/db:/var/lib/mysql \
>      mariadb

Check the docker running container and see that db_nextcloud is running under theNAMES column. You can also see the port we configured.

qinkangdeid@omv:~$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

Another way to verify the installation is using telnet

III. Install NextCloud

The installation of NextCloud is also simple. Still using docker, copy the following command to the terminal and run it. Remember that the first part of -v is the address of your host machine.

docker run -d --name nextcloud \
       -p 8088:80 \
       --restart=unless-stopped \
       -v /sharedfolders/nextcloud/html:/var/www/html \
       -v /sharedfolders/nextcloud/data:/var/www/html/data \
       nextcloud

Explanation of command parameters
(For specific parameter definitions, please see nextcloud official images site ):

-p 8088:80: The port opened by the container service, the former is the port of the host machine, and the latter is the port of the service inside the container

--restart=unless-stopped: restart the container when the container is stopped

-v: data volume binding The former is the address of the host machine, the latter is the location of the container machine

Nextcloud installation and all data (file upload, etc.) outside the database are stored in the container address /var/www/html. If you want to persist your data, you can view it without going through nextCloud, it should be mapped to the host machine Somewhere

There are still a lot of volume configurations for Nextcloud, such as config, data, themes, etc.

Some volume addresses of nextcloud:
/var/www/html home folder required for update
/var/www/html/custom_apps manually installed application location
/var/www/html/config Local configuration file location
/var/www/html/data Where your network disk data is stored
/var/www/html/themes/<YOU_CUSTOM_THEME> theme file location
For the above volume mapping, I only extracted the data here. All other configurations are placed in the location of /var/www/html by default.

Following is the log I run

qinkangdeid@omv:~$ docker run -d --name nextcloud \
>        -p 8088:80 \
>        --restart=unless-stopped \
>        -v /sharedfolders/nextcloud/html:/var/www/html \
>        -v /sharedfolders/nextcloud/data:/var/www/html/data \
>        nextcloud

Visit NextCloud

I mapped the nextcloud service port to the host’s port 8088. After nextcloud starts, the browser can enter http://your IP:8088 to access nextcloud.

The interface at the beginning is as follows:

The first configuration is to configure an administrator username and password to access nextcloud in the future
The second item is the data directory. We have specified the location when we run the container, so we do n’t need to move here.
The third item is to configure the connection information of the external database. Fill in the information we created before mariadb. In fact, you can also connect the previous mariadb container when you install nextcloud. Here you fill it in manually. It should be noted that if the service port of the database is different from the host port, the port of the host must be written here. For example, the service port 3306 of my mariadb container is mapped to the port 3307 of the host. The port is 3307.

After all the information is filled in, click Install to complete. This step will take time. Nextcloud needs to create a database table and some initial configuration information.

Click Install

After the installation is complete, the following site will be displayed automatically

There will be some default example files

At this point nextcloud has been installed, you can continue to explore the features of NextCloud.

IV. NextCloud Extended Installation Method

PS: The above installation method needs to configure the database connection and data volume address when first accessing nextcloud. The following method can reduce this step

docker can use –link to connect to the configuration of another container. Nextcloud also supports Automatic configuration via environment variables. You can pre-configure everything asked on the installation page when the nextcloud container is run for the first time. To enable automatic configuration,
Database connections can be set through the following environment variables. But only one database type can be used!

The environment variables that Nextcloud currently supports are automatically configured as follows:

Configure database environment variables
- For the parameters of the selected SQLITE_DATABASE database:
  - SQLITE_DATABASE: The name of the database when using the SQLite database (we do not use this database so we do not need to take this parameter)
- For the parameters of MYSQL / MariaDB database:
  - MYSQL_DATABASE: The name of the database to use. The database of the mariadb container created here and before has been db_nextcloud
  - MYSQL_USER: database username
  - MYSQL_PASSWORD database username password
  - MYSQL_HOST: The name of the configured database container docker run -d –name db_nextcloud The name specified by the –name parameter, which is db_nextcloud
- For the parameters of the PostgreSQL database:
  - POSTGRES_DB: the name of the postgres database
  - POSTGRES_USER: postgres database username
  - POSTGRES_PASSWORD password of the postgres database user (corresponds to the password of the username above)
  - POSTGRES_HOST: the name of the configured database container
Configure environment variables for Nextcloud administrator user password
- NEXTCLOUD_ADMIN_USER: administrator username
- NEXTCLOUD_ADMIN_PASSWORD: Administrator password
Configure environment variables for Nextcloud data file address and table name prefix
- NEXTCLOUD_DATA_DIR: Nextcloud data storage location (default path is: / var / www / html / data) If this is not set, we can also use the -v parameter to map
- NEXTCLOUD_TABLE_PREFIX: database table table name prefix that nextcloud depends on (default: "") Optional

So the way to create the nextcloud container is slightly changed. You can add it freely according to the above environment variables. The environment variables are appended with -e. I only configure the database environment variables here, as shown in the following command:

docker run -d --name nextcloud \
       --link db_nextcloud:db_nextcloud \
       -p 8088:80 \
       -p 4433:443 \
       -e PUID=1000 \
       -e PGID=100 \
       -v /sharedfolders/nextcloud/html:/var/www/html \
       -v /sharedfolders/nextcloud/data:/var/www/html/data \
       -e MYSQL_DATABASE=nextcloud \
       -e MYSQL_USER=nextcloud \
       -e MYSQL_PASSWORD=123456 \
       -e MYSQL_HOST=db_nextcloud \
       --restart=unless-stopped \
       nextcloud

My execution log:

root@omv:/sharedfolders/nextcloud# docker run -d --name nextcloud \
>        --link db_nextcloud:db_nextcloud \
>        -p 8088:80 \
>        -e PUID=1000 \
>        -e PGID=100 \
>        -v /sharedfolders/nextcloud/html:/var/www/html \
>        -v /sharedfolders/nextcloud/data:/var/www/html/data \
>        -e MYSQL_DATABASE=nextcloud \
>        -e MYSQL_USER=nextcloud \
>        -e MYSQL_PASSWORD=123456 \
>        -e MYSQL_HOST=db_nextcloud \
>        --restart=unless-stopped \
>        nextcloud

After nextcloud starts, the following screen appears when you access nextcloud for the first time:

Database and data volume configuration is gone, just need to create an administrator account

V. Install onlyoffice

onlyoffice is an online office suite that includes viewers and editors for text, spreadsheets and presentations, is fully compatible with Office Open XML formats: .docx, .xlsx, .pptx and supports real-time collaborative editing. onlyoffice official website https://www.onlyoffice.com/

ONLYOFFICE provides a complete suite of efficiency tools including Document Management, Project Management, CRM, Calendar, Mail, and Enterprise Networks.
You no longer have to switch back and forth between multiple applications to perform different tasks.
A centralized, multi-functional system will help you organize every step of your management work, thereby increasing productivity and success.

If you want to get the online preview editing function of the document, then it is recommended that you install onlyoffice online office suite.

NextCloud’s application store has integrated onlyoffice. We only need to install and configure it to connect to the specified onlyoffice document server. Now all we need to do is install onlyoffice document server.

We still install the onlyoffice document server via docker:

docker run -i -t -d --name onlyoffice \
    -p 8000:80 \
    -e PUID=1000 \
    -e PGID=100 \
    --restart=unless-stopped \
