Enabled SSH Server Created Trailpeople Group used TrailPeople gmail account to enable email

I am getting the impression that the management engine (DSM) is running in nginx on port 5000 and that I want to use Apache to support owncloud.

Database engine of choice

I wanted to use PostgreSQL but can't get it to work with owncloud. I tried and tried and gave up. Owncloud does not appear to be sending the username to postgres. I dropped back to Mariadb

Configuration files for postgresql are in /etc/postgresql/ Use a HUP to reconfigure it. killall -1 /usr/bin/postgres

NGINX

When I first got the Syno, I touched the nginx configuration and ended up breaking the DSM app. I backed out my changes.

The file I created for owncloud is in /usr/local/etc/nginx/sites-enabled/owncloud.conf and it looks like this:

server {
  listen 443 default_server ssl;
  listen [::]:443 default_server ssl;

  server_name _;
#  ssl_certificate /etc/ssl/nginx/owncloud.crt;
#  ssl_certificate_key /etc/ssl/private/owncloud.key;

  root /volume1/web/owncloud;
  # set max upload size
  client_max_body_size 10G;
  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;

Packages

Do not install WebStation! It pulls in Apache. I don't want it hanging around. Likewise skip phpMyadmin because it pulls in WebStation.

• Synology Directory Service
• Synology VPN

Enable Synocommunity, https://synocommunity.com/

for owncloud, install

• redis -- http://www.iholken.com/index.php/2016/03/16/install-redis-server-and-phpredis-extension-into-synology-nas-running-dsm-6-without-bootstrapping/
• MariaDB
• debian chroot

I download from owncloud.org because the version in packages is outdated.

wget https://download.owncloud.org/community/owncloud-9.1.2.tar.bz2

Debian packages

sudo -s
sudo /var/packages/chroot/scripts/start_stop_status chroot
apt-get update
apt-get install locales
dpkg-reconfigure locales
dpkg-reconfigure tzdata
apt-get install php5-dev
apt-get install php5-redis

Owncloud 9

http://www.iholken.com/index.php/2016/03/15/guide-for-installing-owncloud-9-to-synology-nas-running-dsm-6/

I did get it going with nginx in spite of his comments on using Apache instead.

Optimizations: fixed because owncloud told me to--

Add /dev/urandom to open_basedir in /usr/local/etc/php56/conf.d/user-settings.ini and then send a HUP to php-fpm

cat fpm.d/env.conf 
; bwilson added this for owncloud

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

Crontab

In the Synology "Task Scheduler" I set this to run every 15 minutes. Add to /etc/crontab:

0,15,30,45 * * * *  http    /bin/php -f /volume1/web/owncloud/cron.php

User authentication

Synology has a pretty good UI in DSM for LDAP, so I enabled their Direcgtory Service package, then set up owncloud to use it.

I should be able to make Linux login (PAM) and Samba use it too. So setting up a password in LDAP should work everywhere.
