<code># yum install owncloud</code>
You most likely want to install one of {{package|owncloud-httpd}} or {{package|owncloud-nginx}}, depending on the web server you wish to use, and at least one of {{package|owncloud-mysql}}, {{package|owncloud-postgresql}} and {{package|owncloud-sqlite}} depending on the database you wish to use. For example:
===SSL certificate configuration===
In order to have secure communications between host and server, you need to generate a key and a certificate


<code># yum install crypto-utils</code>
# yum install owncloud-httpd owncloud-mysql


<code># genkey ''hostname''</code>
if you wish to run ownCloud on [[Apache_HTTP_Server|Apache]] and use a [[MariaDB]] / MySQL database.


Answer "no" to the question "Would you like to send a Certificate Request (CSR) to a Certificate Authority (CA)?"
=== Enabling and starting the web server ===


To allow httpd service to use SSL, you need to install proper dependencies
You will need to enable and start the web server. For Apache:


<code># yum install mod_ssl openssl</code>
# systemctl enable httpd.service
# systemctl start httpd.service


and apply the following editings to
See the [[Apache_HTTP_Server|Apache page]] for more detailed instructions on installing and configuring Apache.


<code>/etc/httpd/conf.d/ssl.conf</code>
=== Enabling, starting and configuring the database server ===


putting at the bottom
If you choose to use SQLite, no special configuration is required. However, please be aware that SQLite is not a good choice for even moderately-sized or public deployments, and should really only be used for small private deployments or testing.
<pre>
SSLCertificateFile /etc/pki/tls/certs/hostname.crt
SSLCertificateKeyFile /etc/pki/tls/private/hostname.key
</pre>


To force SSL usage in Owncloud server:
==== [[MariaDB]] / MySQL ====


<code># nano /etc/owncloud/config.php</code>
If you use MariaDB / MySQL, you will need to enable and start the database server. It is then strongly recommended to secure the server configuration.


e modify entry
# systemctl enable mysqld.service
# systemctl start mysqld.service
$ mysql_secure_installation


<code>'forcessl' => false</code>
You should then create a database and a user for ownCloud to use.


as the following one
$ mysql -u root -p
  CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
  CREATE DATABASE IF NOT EXISTS owncloud;
  GRANT ALL PRIVILEGES ON owncloud.* TO 'username'@'localhost' IDENTIFIED BY 'password';


<code>'forcessl' => true,</code>
Set the username as you like (but 'owncloud' is always a safe choice...), and choose a strong password (it will be saved in your ownCloud configuration, so there's no need to worry about convenience in re-typing or remembering it).


For more information on MariaDB / MySQL deployment and configuration on Fedora, see [[MariaDB]]. You can also refer to the excellent [https://mariadb.com/kb/en/mariadb/documentation/ upstream documentation].


To create admin user, insert into the browser (ignoring warning about unsigned certificate)
==== [[PostgreSQL]] ====


<code>localhost/owncloud</code>
If you use PostgreSQL, you will need to initialize the server before enabling and starting it.


In case of troubles, try restarting Apache service
# postgresql-setup initdb
# systemctl enable postgresql.service
# systemctl start postgresql.service


<code># systemctl restart httpd</code>
You will also need to configure SELinux to allow the web server to connect to the PostgreSQL server via TCP/IP:


==Grant remote access to the server==
# setsebool -P httpd_can_network_connect_db on
===Firewall configuration===
You need to find out the active firewall zone


<code># firewall-cmd --list-all-zones | grep active</code>
and configure PostgreSQL to use password authentication for local TCP/IP connections. To do this, edit {{filename|/var/lib/pgsql/data/pg_hba.conf}} and change the mechanism from 'ident' to 'password' on the lines that configure TCP/IP connections from localhost, 127.0.0.1, and ::0. The line for the 'local' TYPE does not apply to ownCloud, as it does not use local socket access to PostgreSQL servers. More information on this file can be found in the [http://www.postgresql.org/docs/current/static/auth-pg-hba-conf.html PostgreSQL documentation].


in our case:
Now you will need to create a database and user for ownCloud to use.


<code>public (default, active)</code>
# su - -c "psql" postgres
  CREATE USER username WITH PASSWORD 'password';
  CREATE DATABASE owncloud TEMPLATE template0 ENCODING 'UNICODE';
  ALTER DATABASE owncloud OWNER TO username;
  GRANT ALL PRIVILEGES ON DATABASE owncloud TO username;


then we will use the following commands to allow access to http and https services
Set the username as you like (but 'owncloud' is always a safe choice...), and choose a strong password (it will be saved in your ownCloud configuration, so there's no need to worry about convenience in re-typing or remembering it).
<pre># firewall-cmd --permanent --zone=public --add-service=http
# firewall-cmd --permanent --zone=public --add-service=https
# systemctl restart firewalld</pre>


===Configuring Apache permissions===
It is also a good idea to set a password for the postgres user within PostgreSQL, which you can do with {{command|\password postgres}} from the PostgreSQL prompt.
In order to allow access to remote hosts, you need to configure Apache's


<code>/etc/httpd/conf.d/owncloud.conf</code>
For more details on PostgreSQL deployment and configuration on Fedora, see [[PostgreSQL]]. You can also refer to the excellent [http://www.postgresql.org/docs/current upstream documentation].


as the following example:
=== TLS certificate configuration ===


<pre>
See the [[Apache_HTTP_Server|Apache page]] for details on configuring Apache for TLS/SSL connections.
<IfModule mod_authz_core.c>
# Apache 2.4
#Require local
Require all granted
</IfModule>
<IfModule !mod_authz_core.c>
# Apache 2.2
Order Deny,Allow
#Deny from all
#Allow from 127.0.0.1
#Allow from ::1
Allow from all
</IfModule>
</pre>


===Configuration of exposed IP addresses===
If you wish, you can configure your ownCloud server to only use TLS/SSL connections. Create a file {{filename|/etc/owncloud/forcessl.config.php}} with these contents:
Finally you need to set into configuration file


<code>/etc/owncloud/config.php</code>
<?php
$CONFIG = array (
  'forcessl' => true,
);


at entry
Now whenever someone tries to connect to any ownCloud page without using TLS/SSL, they will be automatically redirected to the appropriate TLS/SSL URL.


<pre>array (
=== Initial ownCloud setup ===
  0 => 'localhost',
)</pre>
the IP addresses with which the server will be exposed outside (both LAN and WAN). An example of configuration with IP addresses for both LAN and WAN is:
<pre>
array (
  0 => 'localhost',
  1 => '192.168.1.100',
  2 => '200.100.1.100',
)
</pre>
 
== Troubleshooting ==


=== Dynamic IP adress ===
To perform initial ownCloud configuration, browse to http://localhost or https://localhost (adding a trust exception for your self-signed certificate, if you used one) from the server. If you wish to perform initial configuration from a browser running on a different machine, you will need to refer to [[Apache_HTTP_Server#webapp-access-control|these instructions for broadening access to ownCloud]] and [[Apache_HTTP_Server#firewall-configuration|these instructions for opening firewall ports]]. Please ensure you do not expose the initial configuration wizard to public access!


If you have a dynamic IP address you can configure a dynamic DNS client, for example [[inadyn-mt]] to update your ip for your DNS server account
In initial configuration, you will set an administrator username and password, and set your database configuration. If using MariaDB / MySQL or PostgreSQL, enter the appropriate username and password for the database you created earlier.


In case of trouble, try restarting the Apache service:

Revision as of 02:52, 29 August 2014

ownCloud is a web application that implements "cloud" services such as file storage and sharing, contact and calendar hosting and more. This page will help you set up an ownCloud server running on a Fedora system. See also the official documentation (though we advise against using upstream's ownCloud packages from the Open Build Service: this guide uses Fedora's own ownCloud packages).

Features

  • Online file storage
  • Android compatibility
  • Contacts (CardDAV) and calendar (CalDAV) synchronization
  • Music streaming
  • Many more

Installation

You most likely want to install one of owncloud-httpd or owncloud-nginx, depending on the web server you wish to use, and at least one of owncloud-mysql, owncloud-postgresql and owncloud-sqlite depending on the database you wish to use. For example:

# yum install owncloud-httpd owncloud-mysql

if you wish to run ownCloud on Apache and use a MariaDB / MySQL database.

Enabling and starting the web server

You will need to enable and start the web server. For Apache:

# systemctl enable httpd.service
# systemctl start httpd.service

See the Apache page for more detailed instructions on installing and configuring Apache.

Enabling, starting and configuring the database server

If you choose to use SQLite, no special configuration is required. However, please be aware that SQLite is not a good choice for even moderately-sized or public deployments, and should really only be used for small private deployments or testing.

MariaDB / MySQL

If you use MariaDB / MySQL, you will need to enable and start the database server. It is then strongly recommended to secure the server configuration.

# systemctl enable mysqld.service
# systemctl start mysqld.service
$ mysql_secure_installation

You should then create a database and a user for ownCloud to use.

$ mysql -u root -p
  CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
  CREATE DATABASE IF NOT EXISTS owncloud;
  GRANT ALL PRIVILEGES ON owncloud.* TO 'username'@'localhost' IDENTIFIED BY 'password';

Set the username as you like (but 'owncloud' is always a safe choice...), and choose a strong password (it will be saved in your ownCloud configuration, so there's no need to worry about convenience in re-typing or remembering it).

For more information on MariaDB / MySQL deployment and configuration on Fedora, see MariaDB. You can also refer to the excellent upstream documentation.

PostgreSQL

If you use PostgreSQL, you will need to initialize the server before enabling and starting it.

# postgresql-setup initdb
# systemctl enable postgresql.service
# systemctl start postgresql.service

You will also need to configure SELinux to allow the web server to connect to the PostgreSQL server via TCP/IP:

# setsebool -P httpd_can_network_connect_db on

and configure PostgreSQL to use password authentication for local TCP/IP connections. To do this, edit /var/lib/pgsql/data/pg_hba.conf and change the mechanism from 'ident' to 'password' on the lines that configure TCP/IP connections from localhost, 127.0.0.1, and ::0. The line for the 'local' TYPE does not apply to ownCloud, as it does not use local socket access to PostgreSQL servers. More information on this file can be found in the PostgreSQL documentation.

Now you will need to create a database and user for ownCloud to use.

# su - -c "psql" postgres
  CREATE USER username WITH PASSWORD 'password';
  CREATE DATABASE owncloud TEMPLATE template0 ENCODING 'UNICODE';
  ALTER DATABASE owncloud OWNER TO username;
  GRANT ALL PRIVILEGES ON DATABASE owncloud TO username;

Set the username as you like (but 'owncloud' is always a safe choice...), and choose a strong password (it will be saved in your ownCloud configuration, so there's no need to worry about convenience in re-typing or remembering it).

It is also a good idea to set a password for the postgres user within PostgreSQL, which you can do with \password postgres from the PostgreSQL prompt.

For more details on PostgreSQL deployment and configuration on Fedora, see PostgreSQL. You can also refer to the excellent upstream documentation.

TLS certificate configuration

See the Apache page for details on configuring Apache for TLS/SSL connections.

If you wish, you can configure your ownCloud server to only use TLS/SSL connections. Create a file /etc/owncloud/forcessl.config.php with these contents:

<?php
$CONFIG = array (
  'forcessl' => true,
);

Now whenever someone tries to connect to any ownCloud page without using TLS/SSL, they will be automatically redirected to the appropriate TLS/SSL URL.

Initial ownCloud setup

To perform initial ownCloud configuration, browse to http://localhost or https://localhost (adding a trust exception for your self-signed certificate, if you used one) from the server. If you wish to perform initial configuration from a browser running on a different machine, you will need to refer to these instructions for broadening access to ownCloud and these instructions for opening firewall ports. Please ensure you do not expose the initial configuration wizard to public access!

In initial configuration, you will set an administrator username and password, and set your database configuration. If using MariaDB / MySQL or PostgreSQL, enter the appropriate username and password for the database you created earlier.

In case of trouble, try restarting the Apache service:

# systemctl restart httpd

Grant remote access to the server

Once you have run initial configuration on your server, you can refer to these instructions for broadening access to ownCloud and these instructions for opening firewall ports in order to allow access to your server from any host. Remember that if your server is running behind a NAT router and you wish to allow access from outside your local network, you will need to configure the router to forward the HTTP and HTTPS ports to your server. Configuring DNS is outside the scope of this documentation.
