OwnCloud is a Dropbox-like solution for self-hosted file sharing and syncing. Installing OwnCloud 10 on CentOS is quite simple. Whether you want to backup, have file-syncing or just have a Google Calendar alternative, this guide is for you.

What is OwnCloud? Is it like a “cloud”?

If you stumbled here by chance and don’t know what OwnCloud is, here is an article explaining its principal features and advantages/disadvantages. In this other article you can find OwnCloud 10 new features. To tell you the truth, OwnCloud is a SaaS cloud, if you want to know more about cloud types you can read this article.

In this article we will cover the installation of the server (not the client).

Step 1: Add the repositories

Important

I take absolutely NO responsibility of what you do with your machine; use this tutorial as a guide and remember you can possibly cause data loss if you touch things carelessly.

The first step is to add the repositories to your system. You will need root access during this procedure. The following procedure will install apache as webserver. Since CentOS 7 ships with PHP 5.4 by default but OwnCloud requires at least PHP 5.6 we’ll also be installing PHP 7 from a third-party repository. The following procedure will install apache as webserver. Input the commands one by one to avoid errors! Input the commands one by one to avoid errors!

CentOS 7

If you’d rather use PHP 7.1, you can follow this tutorial: how to install PHP 7.1 on CentOS 7.

Warning!

If you decided to use PHP 7.1 rather than PHP 7.0 using the past tutorial, replace each instance of php70w with php71w in all the successive commands.

Open a terminal and input the following commands:

# yum install epel-release

# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

# yum install httpd php70w php70w-dom php70w-mbstring php70w-gd php70w-pdo php70w-json php70w-xml php70w-zip php70w-curl php70w-mcrypt php70w-pear php70w-intl setroubleshoot-server

# rpm --import https://download.owncloud.org/download/repositories/10.0/CentOS_7/repodata/repomd.xml.key

# curl https://download.owncloud.org/download/repositories/10.0/CentOS_7/ce:10.0.repo | tee /etc/yum.repos.d/owncloud_CE:10.0.repo

# yum install owncloud

These commands will add the repositories that contain the software and install it on your machine.

Step 2: Database selection

Now that you got the OwnCloud software, all that is left is to choose a database that will support the installation. You have three choices:

• SQLite: is a single-file database. It is suggested only for small installations since it will slow OwnCloud down sensibly.
• MariaDB/MySQL: are popular open source databases especially amongst web developers. It is the suggested choice.
• PostgreSQL: a popular enterprise-class database. More complicated than MySQL/MariaDB.

Now, this choice won’t really alter the functionality of OwnCloud (except if you use SQLite), so pick whatever you know best. If you’re unsure pick MariaDB/MySQL.

SQLiteMariaDB/MySQLPostgreSQL

Install the software:

# yum install mariadb-server php70w-mysql

# mysql_secure_installation

During the installation you will be prompted to choose a root password, pick a strong one.

Start (and enable at boot) the service:

# systemctl start mariadb

# systemctl enable mariadb

Now you need to enter the database (you will be asked the password you just set):

$ mysql -u root -p

Now that you are in create a database:

CREATE DATABASE owncloud;

Now you need to create the user that will be used to connect to the database:

CREATE USER 'oc_user'@'localhost' IDENTIFIED BY 'YOUR_PASSWORD_HERE';

The last step is to grant the privileges to the new user:

GRANT ALL PRIVILEGES ON owncloud.* TO 'oc_user'@'localhost';

FLUSH PRIVILEGES;

When you’re done type Ctrl-D to exit.

Step 3: Setting Apache and SELinux

In this step we’ll start (and enable) the webserver and we’ll set SELinux up. Now, many tutorials will tell you to disable SELinux (because it is a difficult component to manage). Instead, I suggest you to keep it on and add the rules for OwnCloud:

CentOS 7

Add SELinux rules:

# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/data(/.*)?'

# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/config(/.*)?'

# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/apps(/.*)?'

# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/.htaccess'

# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/owncloud/.user.ini'

# restorecon -Rv '/var/www/html/owncloud/'

If you decided to use Mariadb/MySQL/PostgreSQL, you also need to allow apache to access the database:

# setsebool -P httpd_can_network_connect_db 1

Now that you’ve configured SELinux let’s start and enable Apache:

CentOS 7

Start (and enable at boot) the service:

# systemctl start httpd

# systemctl enable httpd

Step 4: Configuring firewall

This step is essential when your firewall is enabled. If your firewall is enabled you won’t be able to access your OwnCloud 10 instance; on the other hand if it isn’t enabled you shouldn’t have any problems and you can simply skip this step. 

Tip!

Keep in mind having a firewall enabled is a good security practice and you should already have one enabled.

In order for the firewall to work, it must be enabled. This guide will not include this part. When you enable a firewall many things can go wrong, e.g. you’re using SSH, you enable the firewall and your connection is cut and can’t connect otherwise, hence you should carefully review the documentation from your distribution.

To open the ports needed by OwnCloud 10 follow these steps:

FirewallDIPtables

FirewallD is a newer firewall used to simplify firewall management. If you’re using it you can simply do:

# firewall-cmd --add-service http --permanent

# firewall-cmd --add-service https --permanent

# firewall-cmd --reload

Step 5: Install

Once you’re done with selecting the database, it’s time to install everything. Head to http://YOUR_IP_ADDRESS/owncloud/ and you will be facing the following screen:

OwnCloud 10 installation

Select an administrator username and password, then you can select the data folder, but if you don’t know what you’re doing it’s best if you leave it with the default value. Then click on “Storage & Database” to select the database you chose during step 2. Fill everything and if you’ve followed all the steps correctly you should be seeing the Files app:
