For anyone interested, I just wrote this install guide for myself
last week. It removes all the errors from owncloud except the
urandom error.

# Owncloud Setup
### requirements
- ssl certificates
- database
- php
- owncloud
- httpd
- redis
### create self-signed ssl certificate and private key for owncloud
see _create certificates.md_
### install postgresql database server
see _postgresql setup.md_
### install phpPgAdmin
see _phpPgAdmin setup.md_
### install owncloud and php PostgreSQL drivers
`$ pkg_add -iv owncloud php-pdo_pgsql redis`
When promted, pick the latest version of php. After the installation has
finished, create the symlinks as shown by `pkg_add`. Also check the
pkg-readmes
Open _php-fpm.conf_ and change the following lines:
;env[PATH] = /usr/local/bin:/usr/bin:/bin
env[PATH] = /usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:sbin
;pm.max_children = 5
pm.max_children = 10
Open `/var/www/owncloud/config/config.php` and add the following:
'datadirectory' => '/owncloud/data',
'updatechecker' => false,
'log_type' => 'syslog',
'syslog_tag' => 'owncloud',
'logfile' => '/var/log/owncloud',
'loglevel' => 2,
'memcache.locking' => '\OC\Memcache\Redis',
'memcache.local' => '\OC\Memcache\Redis',
'redis' => array(
'host' => 'localhost',
'port' => 6379,
'timeout' => 0.0,
),
Create owncloud log file
`$ touch /var/log/owncloud`
`$ chmod 640 /var/log/owncloud`
Edit `/etc/syslog.conf`, prepend the following:
!!owncloud
*.* /var/log/owncloud
!*
Setup log rotation, append the following to `/etc/newsyslog.conf`
/var/log/owncloud 640 5 30 * Z
Reload syslogd
rcctl reload syslogd
### create ownCloud database
$ psql -U postgres
$ postgres=# CREATE USER owncloud WITH PASSWORD 'password';
$ CREATE ROLE
$ postgres=# CREATE DATABASE owncloud TEMPLATE template0 ENCODING
'UNICODE';
$ CREATE DATABASE
$ postgres=# ALTER DATABASE owncloud OWNER TO owncloud;
$ ALTER DATABASE
$ postgres=# GRANT ALL PRIVILEGES ON DATABASE owncloud TO owncloud;
$ GRANT
$ postgres=# \q
### setup httpd daemon
The following files are required by owncloud and must therefore be made
available inside the chroot where owncloud resides.
`$ mkdir -p /var/www/usr/share/locale/UTF-8/`
`$ cp /usr/share/locale/UTF-8/LC_CTYPE /var/www/usr/share/locale/UTF-8/`
`$ mkdir /var/www/etc`
`$ cp /etc/{hosts,resolv.conf,localtime} /var/www/etc/`
Create httpd.conf.
`$ touch /etc/http.conf`
# set macros
ext_if="egress"
domain="www.myowncloud.com"
# Include MIME types instead of the built-in ones
types {
include "/usr/share/misc/mime.types"
}
server "default" {
listen on $ext_if port 80
block return 301 "https://www.myowncloud.com$REQUEST_URI";
}
server $domain {
listen on $ext_if tls port 443
# set certificates for owncloud
tls {
certificate "/etc/ssl/server.crt"
key "/etc/ssl/private/server.key"
}
# Enable HTTP Strict Transport Security
# set max-age as suggested by owncloud
hsts max-age 15768000
# Set max upload size to 513M (in bytes)
connection max request body 537919488
root "/owncloud"
# First deny access to the specified files
location "*/db_structure.xml" { block }
location "*/.ht*" { block }
location "*/README" { block }
location "*/data*" { block }
location "*/config*" { block }
# If it is accessed as /owncloud
location "/owncloud/*.php*" {
root { "/owncloud", strip 1 }
fastcgi socket "/run/php-fpm.sock"
}
location "/owncloud/*" {
root { "/owncloud", strip 1 }
}
# Any other PHP file
location "/*.php*" {
fastcgi socket "/run/php-fpm.sock"
}
}
### add rules to pf.conf firewall
pass in inet proto tcp from any to self port http
pass in inet proto tcp from any to self port https
### reload pf
`$ pfctl -f /etc/pf.conf`
### add cronjob
`$ crontab -u www -e`
webcron
*/15 * * * * /usr/bin/ftp -S dont -Vo -
https://myowncloud.example.com/owncloud/cron.php > /dev/null
cron
*/15 * * * * php -f /var/www/owncloud/cron.php
> /dev/null 2>&1
### add redis, php-fpm and httpd rc scripts to rc.conf.local and start
deamons
`$ rcctl enable redis php56_fpm httpd`
`$ rcctl start redis php56_fpm httpd`
