Intro :

OwnCloud is an open source file sharing and data synchronization program .

We will learn In this lesson install 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 /var/lib/, 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: my_strong_password.
So, execute the command:

# mysql -u root -p

and then:

mysql> CREATE DATABASE my_owncloud_db;
mysql> CREATE USER ocuser@localhost IDENTIFIED BY 'my_strong_password';
mysql> GRANT ALL PRIVILEGES ON my_owncloud_db.* to ocuser@localhost 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 /usr/share/nginx/html/:

# unzip owncloud-9.1.2.zip
# mv owncloud/ /usr/share/nginx/html/

Go to the Nginx root directory; there, create a new data 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;
}
 
server {
    listen 80;
    server_name data.owncloud.co;
    # enforce https
    return 301 https://$server_name$request_uri;
}
 
server {
    listen 443 ssl;
    server_name storage.example.com;
 
    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
