Prussian a CentOS v6.x & Nginx, OwnCloud Instance

 [Note: This was written in Jan 2014. As of Feb 2015 php v5.4 is required for owncloud v8. See remi repo]


  • A CentOS v6.x VM
    • with the time synchronised
    • a large data volume mounted as /mnt/data
  • http reverse proxy with TLS/SSL offload 

 Note: The VM already has the time synchronised.


Install Nginx from the Nginx repository and OwnCloud from the OwnCloud repository.

# rpm -Uvh
# yum install nginx

Install the EPEL repository so that OwnCloud dependencies are staisfied:

# rpm -Uvh

The CentOS OwnCloud instructions are:

# cd /etc/yum.repos.d/
# wget
# yum install owncloud

Install php-fpm:

# yum install php-fpm

The OwnCloud documentation only recommends the default database for single user installations. Migrations look to be non-trivial. Install and use MySQL server from the start:

# yum install mysql-server

Configure php-fpm

Use the default '/etc/php-fpm.d/www.conf':

listen =
listen.allowed_clients =
user = apache
group = apache
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
slowlog = /var/log/php-fpm/www-slow.log
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session

env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

Start the FPM process:

# chkconfig php-fpm on
# service php-fpm start

Configure Nginx

Move the example and deault configurations out of the way (e.g. '/etc/nginx/conf.d/default.conf'). Create a new OwnCloud Nginx configuration file '/etc/nginx/conf.d/owncloud.conf':

# OwnCloud (ssl/tls)
server {
  listen        80;

  root          /var/www/html/owncloud;

  index         index.php;
  client_max_body_size 1000M; # set maximum upload size

  # deny direct access
  location      ~ ^/(data|config|\.ht|db_structure\.xml|README) {
    deny         all;

  # default try order
  location / {
    try_files $uri $uri/ @webdav;

  # owncloud WebDAV
  location @webdav {
    fastcgi_split_path_info ^(.+\.php)(/.*)$;
    fastcgi_pass  ;
    fastcgi_param           SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param           HTTPS on;
    include                 fastcgi_params;

  # enable php
  location ~ \.php$ {
    try_files               $uri = 404;
    fastcgi_pass  ;
    fastcgi_param           SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param           HTTPS on;
    include                 fastcgi_params;

Add the Nginx user to the apache group. The distribution RPM and the php-fpm pache all assume apache (httpd) is used.

# usermod -a -G apache nginx

This configuration assumes:

  1. that the TLS/SSL offload is performed somewhere else
  2. that owncloud is the default web site (i.e. no virtual hosting)

Start the Nginx server:

# service nginx start

Configure MySQL

Change the mysql configuration '/etc/my.cnf' to only listen on the loopback interface. 

bind-address = localhost

Start mySQL server

# chkconfig mysqld on
# service mysqld start

Lock down the MySQL installation and set the root password:

# mysql_secure_installation

Create the owncloud database

# mysql -u root
mysql> CREATE USER 'owncloud'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON owncloud.* TO 'owncloud'@'localhost' IDENTIFIED BY 'password';
mysql> ^D 


Configure OwnCloud

Change the ownership of '/mnt/data' to apache so that the php process can access the data. Having a data volume out of the web hierarchy reduces the chance of data loss and allows an arbitrarly sized volume to be put into the VM.

# chown apache.apache /mnt/data

Use a web browser to view the owncloud instance, and fill in the setup information:

MySQL config

# mysql_secure_installation


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n]
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n]
 ... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!
