Prerequisites

• A fresh installation of CentOS 7 with SSH enabled.
• This guide assumes that you are connected as the root user.

Prepare the Server

According to ownCloud documentation the supported environments for best performance, stability, support, and full functionality are:

First, make sure the server is up to date:

yum update -y && yum upgrade

The current installed version should be CentOS Linux release 7.8.2003 (Core).
You can check the version by issuing:

cat /etc/centos-release

Install and configure the LAMP stack

In this section, we’ll be installing the LAMP (Linux, Apache, MySQL, PHP) stack as a prerequisite for ownCloud to function properly.

Enable additional repositories

Enter the following commands in order to install and enable the EPEL (Extra packages for Enterprise Linux) and Remi repositories:

yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm

CentOS 7 ships by default with PHP 5 thus, the Remi repository is needed to retrieve and install PHP 7.
Next, using yum-config-manger, disable remi-php54 and enable remi-php73.
yum-config-manger is provided by the package yum-utils.

yum install -y yum-utils
yum-config-manager --disable remi-php54
yum-config-manager --enable remi-php73

Install Apache Web Server, MySQL(MariaDB) and php

Install the following packages:

yum install -y httpd php php-mysqlnd php-intl php-dom php-mbstring php-gd php-pdo php-json php-xml php-zip php-gd php-curl php-pecl-mcrypt php-pear unzip mariadb-server mariadb

Enable and start httpd service:

systemctl enable httpd.service
systemctl start httpd.service

Configure the Database

In this section, we enable and start the MariaDB service and create a new database and relative user for onwCloud.

Enable and start mariadb service:

systemctl enable mariadb.service
systemctl start mariadb.service

Next, configure the security settings for MariaDB issuing mysql_secure_installation. Make sure to chose a strong password:

Enter current password for root (enter for none):
Set root password? [Y/n] Y
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

Create DB and user:

Login as root to MariaDB:

mysql -u root -p

Now it’s time to create a database and relative user for ownCloud:

GRANT ALL ON owncloud_db.* TO 'owncloud_user'@'localhost' IDENTIFIED BY '<YourPassword>';
FLUSH PRIVILEGES;
EXIT;

Install onwCloud

This section explains how to install onwCloud Server from the official repository for the CentOS 7 distribution.
This is the quickest and easiest method for setting up a single standalone onwCloud server.
For large production distributed deployments, the recommended method would be to downloading and installing the tarball version.
For more information, please refer to the official ownCloud Documentation.

Add ownCloud repository

ownCloud packages repository is available at the following URL: https://download.owncloud.org/download/repositories/production/owncloud/

Use the below commands in order to enable the repository and install the owncloud-files package.

rpm --import https://download.owncloud.org/download/repositories/stable/CentOS_7/repodata/repomd.xml.key
curl -L https://download.owncloud.org/download/repositories/stable/CentOS_7/ce:stable.repo -o /etc/yum.repos.d/ownCloud.repo

Install using yum

yum clean expire-cache
yum install -y owncloud-files

Configure permissions

Configure permissions for the apache user: chown -R apache:apache /var/www/html/owncloud/

Configure Firewall and SELinux

Allow http and https traffic towards the server from outside using the firewall-cmd command:

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

Configure SELinux as follows:

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/apps-external(/.*)?'
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/'```

Should you get the error -bash: semanage: command not found, please install the policycoreutils-python package:

yum install -y policycoreutils-python

The Installation Wizard

When the ownCloud prerequisites are fulfilled and all ownCloud files are installed, the last step to completing the installation is running the Installation Wizard. This involves just four steps:

1. Point your web browser to http://onwcloud_ip/owncloud
2. Enter your desired administrator’s username and password
3. Configure the database
4. Click Finish Setup

We should be now ready to proceed with the product configuration through the web interface at http://onwcloud_ip/owncloud/.

Next steps

To configure the server to listen for http requests on http://owncloud_ip:8080 insted of http://owncloud_ip/ownCloud, see Configure a custom url and http port.
To add users to your ownCloud server, see Adding users
