Let’s first learn what is OwnCloud? You might be aware of cloud services very well. The online storage platform which can be accessed anytime, data files can be stored and accessed remotely on any computers or even mobile phone. All you need to do id to remember the cloud ID and password.

Owncloud works on the same feature too. It’s a cloud i.e. a cloud file-sharing system. OwnCloud is a program that either installs on your own server or you can have it be hosted off-site if you don’t have a server or don’t need access to your internal file servers.

Basically, OwnCloud provides the following features:

  • It is the private cloud file storage system where the data stored is secure.
  • It keeps the synchronization between all of your computers.

I hope you have understood about OwnCloud.

OwnCloud is based upon PHP, PostgreSQL or MYSQL or Oracle. So it can run over all platforms which meet all these requirements. Let’s understand how to install OwnCloud on CentOS.

Update the repositories

The first step before you install OwnCloud on CentOS, is to refresh the repositories. For this, we will use the yum command. Basically, YUM stands for YelloDog Updater Modifier, which allows users and system administrators to easily install, update, remove or search software packages. It’s important to refresh the repositories first before installing any new packages. The command for this is as follows:

yum -y update

Install Apache, PHP, and MariaDB

These are some modules that are required to be installed before installing OwnCloud. The OwnCloud server is based on these platforms. Basically, this is called the LAMP stack. We will have a look at the command to install Apache server, MariaDB and PHP modules.

The command to install the Apache server is as follows:

sudo yum install httpd

After this, you have to make some configurations, for this follow the guide: Click Here

Install OwnCloud on CentOS Using Official Tarball

After successfully installing all the packages, we need to install the OwnCloud. We will use wget command to download the tar file. wget command is useful as it downloads the files from web servers using HTTP, HTTPS, and FTP protocols. Extract the downloaded file using tar command. Don’t forget to change its directory. Let’s have a look at the command below:

Don’t forget to extract the file in /var/www/html directory.

Grant permissions

The next step is to grant permission of the webserver to read and write the file on the cloud directory. For this, we will use chown command. Chown command is used to change the ownerships. You can have detailed knowledge of chown command here. The command for this is as follows:

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

Database Configurations

For this, it’s important to install MariaDB as the command is provided above. After installing MariaDB, you need to secure its installation i.e. to set some configurations. Use the following command to do so:


Set the password, and respond YES to all the asked questions. Now, we need to create the database and user named OwnCLoud. You can set a name according to your choice. Then, grant all the privileges to the user over the database. This can be done using the following command:

mysql -u root -p
>CREATE USER `owncloud`@`localhost` IDENTIFIED BY '1234';
>GRANT ALL ON owncloud.* TO `admin`@`localhost`;
Run Mysql Commands Step11
Run Mysql Commands

Apache Web Server Configurations

We are done with the database configurations, the next step is to set Apache Web Server configurations. For this, open the external configuration file for OwnCloud. We will use vi editor. You can use any of the editors. You can also prefer nano command. It depends on your choice. The command for this is as follows:

 sudo vim /etc/httpd/conf.d/owncloud.conf

Add the following code as given below:

Alias /owncloud "/var/www/html/owncloud/"

<Directory /var/www/html/owncloud/>
  Options +FollowSymlinks
  AllowOverride All

 <IfModule mod_dav.c>
  Dav off

 SetEnv HOME /var/www/html/owncloud
 SetEnv HTTP_HOME /var/www/html/owncloud

Configure Owncloud File Step 12
Configure Owncloud File

Folks, Don’t forget to save the changes. Press Esc command followed by “:wq!” command to exit the text editor. After saving the changes, you need to restart the apache services using the restart command. This will be done using systemctl commons. The command for this is as follows:

sudo systemctl restart httpd

After restarting the services, you can check the status of the Apache server using the following command:

sudo systemctl status httpd
Start Serivice Http Step 6
Start Service Http

You can see the status as active in the above figure shown. Here, we need to add the additional step regarding SELinux. SELinux is basically the security of the Linux which has its own database. You can have a detailed knowledge of SELinux Official Documentation. The command for this is as follows:

sudo setsebool -P httpd_unified 1
