# Installing Nextcloud from the Command Line

It is now possible to install Nextcloud entirely from the command line. This is convenient for scripted operations, headless servers, and sysadmins who prefer the command line. There are three stages to installing Nextcloud via the command line:

1. Download the Nextcloud code and unpack the tarball in the appropriate directories. (See Manual Installation on Linux.)

2. Change the ownership of your `nextcloud` directory to your HTTP user, like this example for Debian/Ubuntu. You must run `occ` as your HTTP user; see Run occ As Your HTTP User:

    $ sudo chown -R www-data:www-data /var/www/nextcloud/

3. Use the `occ` command to complete your installation. This takes the place of running the graphical Installation Wizard:

    $ cd /var/www/nextcloud/
    $ sudo -u www-data php occ  maintenance:install --database
    "mysql" --database-name "nextcloud"  --database-user "root" --database-pass
    "password" --admin-user "admin" --admin-pass "password"
    Nextcloud is not installed - only a limited number of commands are available
    Nextcloud was successfully installed

Note that you must change to the root Nextcloud directory, as in the example above, to run `occ maintenance:install`, or the installation will fail with a PHP fatal error message.

Supported databases are:

    - sqlite (SQLite3 - Nextcloud Community edition only)
    - mysql (MySQL/MariaDB)
    - pgsql (PostgreSQL)
    - oci (Oracle 11g currently only possible if you contact us at https://nextcloud.com/enterprise as part of a subscription)

See Command Line Installation for more information.

Finally, apply the correct strong permissions to your Nextcloud files and directories (see Setting Strong Directory Permissions). This is an extremely important step. It helps protect your Nextcloud installation, and ensures that it will run correctly.

## BINLOG_FORMAT = STATEMENT

If your Nextcloud installation fails and you see this in your Nextcloud log:

    An unhandled exception has been thrown: exception ‘PDOException’ with message
    'SQLSTATE[HY000]: General error: 1665 Cannot execute statement: impossible to
    write to binary log since BINLOG_FORMAT = STATEMENT and at least one table
    uses a storage engine limited to row-based logging. InnoDB is limited to
    row-logging when transaction isolation level is READ COMMITTED or READ
    UNCOMMITTED.'

See MySQL / MariaDB with Binary Logging Enabled.
