Introduction
OwnCloud 9.1.4 is an open source software for file sharing and data synchronization that is very useful in the enterprise sector, with an easy to use front-end web format.
This tutorial is about installing ownCloud on CentOS 7 with Nginx as your web server.
Install Nginx and PHP
First, install Nginx. This web server is available on EPEL repository, so just add it like this:
# yum install epel-release
and then:
# yum install nginx
Next, install PHP-FPM (FastCGI Process Manager), using webtatic repository, which is added with the following command:
# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Now it is possible to install PHP with other packages required by ownCloud:
# yum install php70w-fpm php70w-cli php70w-json php70w-mcrypt php70w-pear php70w-mysql php70w-xml php70w-gd php70w-mbstring php70w-pdo
Configure PHP-FPM for Nginx
PHP-FPM configuration is done by editing the php7-fpm configuration file:
# $EDITOR /etc/php-fpm.d/www.conf
Search lines containing “user” and “group” and change with:
user = nginx group = nginx
Scroll down, looking for line “listen”, and change the content to:
listen = 127.0.0.1:9000
Next, uncomment the following lines about environment variables:
env[HOSTNAME] = $HOSTNAME env[PATH] = /usr/local/bin:/usr/bin:/bin env[TMP] = /tmp env[TMPDIR] = /tmp env[TEMP] = /tmp
Save and exit.
Now, it’s time to create a new folder in
, with the following command:
# mkdir -p /var/lib/php/session
Change its owner to nginx user:
# chown nginx:nginx -R /var/lib/php/session/
Start nginx and PHP-FPM:
# sudo systemctl start php-fpm # sudo systemctl start nginx
Add to start at boot time (required for daily usage for the machine as server) :
# systemctl enable nginx # systemctl enable php-fpm
Install MariaDB
MariaDB is available in the CentOS repository, so install it with:
# yum install mariadb mariadb-server
Configure the MariaDB root password:
# mysql_secure_installation
During the process, answer the following questions:
Set root password? [Y/n] New password: Re-enter new password: Remove anonymous users? [Y/n] Disallow root login remotely? [Y/n] Remove test database and access to it? [Y/n] Reload privilege tables now? [Y/n]
Login to the MariaDB shell to create a new database and user for ownCloud. In this example, my_owncloud_db is the database name and ocuser is its user. The password is:Â my_strong_password.
So, execute the command:
# mysql -u root -p
and then:
mysql> CREATE DATABASE my_owncloud_db; mysql> CREATE USER [email protected] IDENTIFIED BY 'my_strong_password'; mysql> GRANT ALL PRIVILEGES ON my_owncloud_db.* to [email protected] IDENTIFIED BY 'my_strong_passowrd'; mysql> FLUSH PRIVILEGES;
Generate a SSL Certificate
If none exists, create a new directory for the SSL file:
# mkdir -p /etc/nginx/cert/
Next, generate a new SSL certificate file:
# openssl req -new -x509 -days 365 -nodes -out /etc/nginx/cert/owncloud.crt -keyout /etc/nginx/cert/owncloud.key
Change the permissions with the following command:
# chmod 600 /etc/nginx/cert/*
Download ownCloud
Download ownCloud Server:
# wget https://download.owncloud.org/community/owncloud-9.1.4.zip
Extract the archive and move it to
:
# unzip owncloud-9.1.2.zip # mv owncloud/ /usr/share/nginx/html/
Go to the Nginx root directory; there, create a new
directory for ownCloud:
# cd /usr/share/nginx/html/ # mkdir -p owncloud/data/
Configure a Virtual Host in Nginx
Create a Virtual Host configuration file with the following command:
# $EDITOR /etc/nginx/conf.d/owncloud.conf
Paste the following text into the file:
 upstream php-handler {
   server 127.0.0.1:9000;
   #server unix:/var/run/php5-fpm.sock;
}
Â
server {
   listen 80;
   server_name data.owncloud.co;
   # enforce https
   return 301 https://$server_name$request_uri;
}
Â
server {
   listen 443 ssl;
   server_name storage.example.com;
Â
   ssl_certificate /etc/nginx/cert/owncloud.crt;
   ssl_certificate_key /etc/nginx/cert/owncloud.key;

       access_log off;
   }
}
Save and exit. Next, test Nginx:
# nginx -t
This should display a “Syntax OK” message.
Restart Nginx:
# systemctl restart nginx
Conclusion
The server side configuration is complete. The last thing to do is to go to your ownCloud server URL (storage.example.com in this example) with a web browser and finish the configuration with the graphical front-end. Do this by creating a new admin account, and entering database credentials created in the previous steps. Your cloud storage service is now ready for a daily usage!
