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 /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; # Add headers to serve security related headers # Before enabling Strict-Transport-Security headers please read into this topic first. add_header Strict-Transport-Security "max-age=15552000; includeSubDomains"; add_header X-Content-Type-Options nosniff; add_header X-Frame-Options "SAMEORIGIN"; add_header X-XSS-Protection "1; mode=block"; add_header X-Robots-Tag none; add_header X-Download-Options noopen; add_header X-Permitted-Cross-Domain-Policies none; # Path to the root of your installation root /usr/share/nginx/html/owncloud/; location = /robots.txt { allow all; log_not_found off; access_log off; } # The following 2 rules are only needed for the user_webfinger app. # Uncomment it if you're planning to use this app. #rewrite ^/.well-known/host-meta /public.php?service=host-meta last; #rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last; location = /.well-known/carddav { return 301 $scheme://$host/remote.php/dav; } location = /.well-known/caldav { return 301 $scheme://$host/remote.php/dav; } location /.well-known/acme-challenge { } # set max upload size client_max_body_size 512M; fastcgi_buffers 64 4K; # Disable gzip to avoid the removal of the ETag header gzip off; # Uncomment if your server is build with the ngx_pagespeed module # This module is currently not supported. #pagespeed off; error_page 403 /core/templates/403.php; error_page 404 /core/templates/404.php; location / { rewrite ^ /index.php$uri; } location ~ ^/(?:build|tests|config|lib|3rdparty|templates|data)/ { return 404; } location ~ ^/(?:\.|autotest|occ|issue|indie|db_|console) { return 404; } location ~ ^/(?:index|remote|public|cron|core/ajax/update|status|ocs/v[12]|updater/.+|ocs-provider/.+|core/templates/40[34])\.php(?:$|/) { fastcgi_split_path_info ^(.+\.php)(/.*)$; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param HTTPS on; fastcgi_param modHeadersAvailable true; #Avoid sending the security headers twice fastcgi_param front_controller_active true; fastcgi_pass php-handler; fastcgi_intercept_errors on; fastcgi_request_buffering off; } location ~ ^/(?:updater|ocs-provider)(?:$|/) { try_files $uri $uri/ =404; index index.php; } # Adding the cache control header for js and css files # Make sure it is BELOW the PHP block location ~* \.(?:css|js)$ { try_files $uri /index.php$uri$is_args$args; add_header Cache-Control "public, max-age=7200"; # Add headers to serve security related headers (It is intended to have those duplicated to the ones above) # Before enabling Strict-Transport-Security headers please read into this topic first. #add_header Strict-Transport-Security "max-age=15552000; includeSubDomains"; add_header X-Content-Type-Options nosniff; add_header X-Frame-Options "SAMEORIGIN"; add_header X-XSS-Protection "1; mode=block"; add_header X-Robots-Tag none; add_header X-Download-Options noopen; add_header X-Permitted-Cross-Domain-Policies none; # Optional: Don't log access to assets access_log off; } location ~* \.(?:svg|gif|png|html|ttf|woff|ico|jpg|jpeg)$ { try_files $uri /index.php$uri$is_args$args; # Optional: Don't log access to other assets 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!
Enjoy!
