Install ownCloud on CentOS 7

This installation assumes you are starting from a fresh CentOS 7.x Installation with no other services installed.

Update your OS

yum -y update

Install Apache, SSL, PHP, MariaDB and Nano

yum -y install httpd mod_ssl openssl php php-mysql php-posix mariadb-server mariadb sqlite php-dom php-mbstring php-gd php-pdo nano

*php-posix required for ownCloud’s occ command line configuration software.

Start Apache and MariaDB

systemctl start httpd.service
systemctl start mariadb.service

Set Apache and MariaDB to autostart on boot

systemctl enable httpd.service
systemctl enable mariadb.service

Add http and https to the firewall

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Download ownCloud


Install bzip2 (Required to extract the ownCloud software)

yum install -y bzip2

Extract the software

tar -jxvf owncloud-7.0.0.tar.bz2 -C /var/www/html/

Set Apache ownership permissions

chown -R apache:apache /var/www/html/owncloud/

Database Configuration

Configure MariaDB
Running the following command and answering the associated prompts will help secure the database.


In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): Enter
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] Enter
New Password: RootDatabasePassword
Re-enter new password: RootDatabasePassword
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Enter
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Enter
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] Enter
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Enter
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Create the ownCloud database user and database

mysql -u root -p
Enter password: RootDatabasePassword
Welcome to the MariaDB monitor.  Commands end with ; or \g.

Configure Apache

IP.ADD.RE.SS/owncloud Method

Add the following lines to the Apache owncloud config file

nano /etc/httpd/conf.d/owncloud.conf
Alias /owncloud /var/www/html/owncloud

Options Indexes FollowSymLinks
AllowOverride Allubuntu 16.04 release date
Order allow,deny
allow from all

Save the file

Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Y
File Name to Write: /etc/httpd/conf.d/owncloud.conf Enter Method

Use this method if you will be accessing your ownCloud installation through a domain name vs. using an IP address as shown above.

Create the CSR (certificate signing request)

In order to add instant security before purchasing an SSL (Secure Socket Layer) certificate, you’ll need to create a self-signed certificate.

Use the following link to create the CSR.

Create the Self-Signed Certificate

*Make sure you use the same files names you created in the previous steps!

openssl x509 -req -days 365 -in -signkey -out

Move the certificate files to a secure location

mkdir /etc/httpd/conf/ssl
mv /etc/httpd/conf/ssl/
mv /etc/httpd/conf/ssl/
mv /etc/httpd/conf/ssl/

Configure Apache to use listen on Port 443

Add the following lines to the Apache configuration file:

nano /etc/httpd/conf/httpd.conf
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the
# directive.
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
Listen 80

<IfModule mod_ssl.c>
    Listen 443

Restart MariaDB

Install ownCloud and configure the Admin user

Using the Command Line

Create occ alias

Since we’ll be using the ownCloud occ (ownCloud Console), and this command must be ran as the web server user, create an alias to reduce typing.

alias occ="sudo -u apache /var/www/html/owncloud/occ"

Install ownCloud and setup the database

occ maintenance:install --database "mysql" --database-name "owncloud" --database-user "ownCloudDBUser" --database-pass "ownCloudDBPassword" --admin-user "ownCloudAdmin" --admin-pass "ownCloudAdminPassword"
ownCloud is not installed - only a limited number of commands are available
ownCloud was successfully installed

Complete Setup Using Web Interface

IP.ADD.RE.SS/owncloud Method

Type the IP address of your server directly into your browser’s address bar, followed by /owncloud
owncloudBrowser1 Method

Enter (replace “” with your actual domain) directly into your browser’s address bar.

Enter your Administrator username and password

In the “Create an admin account, enter the username and password you wish to use for your administrator.

It is strongly recommended NOT to use “admin” or “administrator” since these are easily guessed. Using other usernames adds an extra layer of security to your system.


Configure the Storage location

To access the storage and database configuration settings, click “Storage & database” located directly under the “Create and admin account” window.

The default storage path for this configuration is “/var/www/html/owncloud/data”. Leave this as it is for now. We will manually adjust it in the upcoming steps.


Configure the Database

In the “Configure the database” window, click “MySQL/MariaDB”, then enter the username, password and database name you used when you configured the database earlier. Leave “localhost” as it is to ensure remote users cannot access the database.

Save the settings

Click the [Finish setup] button at the bottom of the page.


Close your web browser. We have some more command line work to do!


Secure the data folder

By default, ownCloud installs the data folder directly on the website’s document root. This could allow access to the folder if the site’s .htaccess or folder’s index file becomes corrupt. Instead, we’ll move it to an “off-site” folder.

Move the data/ folder

mv /var/www/html/owncloud/data /home/owncloud-data

*It has been noted by other users that using “/home/owncloud/data” or other matching folder naming techniques tend to fail, so we use “/home/owncloud-data” which has proven to work.

Configure ownCloud to use the new location

nano /var/www/html/owncloud/config/config.php

Now change the following line:

'datadirectory' = '/var/www/html/owncloud/data',


'datadirectory' = '/home/owncloud-data',

Save the change

File Name to Write: /var/www/html/owncloud/config/config.php Enter

Restart Apache

systemctl restart httpd.service
