Log into DigitalOcean and create droplet.

Info supplied by DO:
server x.x.x.x -- (ssh key?)

DB - clouddb
user - clouddbuser
pass - Ist1h1s0k?

Server has been built and now to add required software to the server:
yum install httpd php php-mysql mariadb-server mariadb sqlitephp-dom php-mbstring php-gd php-pdo wget vim mod_ssl nmap mlocate

Configure SELinux
vim /etc/selinux/config (enable)​ I know most articles tell you to disable. stopdisablingselinux.com
shutdown -r now

**updatedb& (Not required but I use the locate command.)**

getenforce

For http:
setsebool -P httpd_unified 1 (http://wiki.centos.org/TipsAndTricks/SelinuxBooleans)

Set firewall:
systemctl enable firewalld
systemctl start firewalld
systemctl status firewalld

firewall-cmd --permanent --zone=public --add-service=ssh
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Setup Self signed SSL. Borrowed heavily from an article at DigitalOcean: http://bit.ly/1Ekadxh ;)

mkdir /etc/httpd/ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/httpd/ssl/apache.key -out /etc/httpd/ssl/apache.crt
vim /etc/httpd/conf.d/ssl.conf
Find #DocumentRoot "/var/www/html" and uncomment.
Set servername. Example: ServerName x.x.x.x:443

Find the SSLCertificateFile and SSLCertificateKeyFile and change to /etc/httpd/ssl.

vim /etc/httpd/conf.d/ssl.conf

SSLCertificateFile /etc/httpd/ssl/apache.crt
SSLCertificateKeyFile /etc/httpd/ssl/apache.key

systemctl restart httpd.service
systemctl status httpd.service

Now to work on Apache and start Mariadb.
cp /etc/httpd/conf/httpd.conf .
sed -i '/^[[:blank:]]*#/d;s/#.*//' /etc/httpd/conf/httpd.conf
sed -i '/^\s*$/d' /etc/httpd/conf/httpd.conf

vim /etc/httpd/conf/httpd.conf (Fix .htaccess parsing.)​

Change AllowOverride None to AllowOverride All​ *AllowOverride controls what directives may be placed in .htaccess files. 
**<Directory "/var/www/html">** If not done this causes an issue with Owncloud.

systemctl restart httpd.service
systemctl start mariadb.service
systemctl enable httpd.service
systemctl enable mariadb.service

**netstat -an | less**

mysql_secure_installation (Yes to all!)

Access DB from CLI
mysql -u root -p
myt3st0C#1

Create database clouddb;
grant all on clouddb.* to 'clouddbuser'@'localhost' identified by 'Ist1h1s0k?'; ** What did we do here?

vim /etc/my.cnf
bind-address = 127.0.0.1

Restart the DB
systemctl restart mariadb.service
systemctl status mariadb.service

**netstat -an | less**

Work on Owncloud install:

(Owncloud: Fix php.ini: This can cause major issues with non-ASCII characters in file names.)
vim /etc/php.ini
Find default_charset and change to UTF-8

Add the repo from:
http://software.opensuse.org/download/package?project=isv:ownCloud:community&package=owncloud

cd /etc/yum.repos.d/
wget http://download.opensuse.org/repositories/isv:ownCloud:community/CentOS_CentOS-7/isv:ownCloud:community.repo
yum install owncloud

Fix SELinux for Owncloud.

semanage fcontext -a -t httpd_sys_rw_content_t /var/www/html/owncloud/data​
restorecon /var/www/html/owncloud/data
semanage fcontext -a -t httpd_sys_rw_content_t /var/www/html/owncloud/config
restorecon /var/www/html/owncloud/config
semanage fcontext -a -t httpd_sys_rw_content_t /var/www/html/owncloud/apps
restorecon /var/www/html/owncloud/apps

systemctl restart httpd.service

Now to access our webserver! Example:
https://*.*.*.*/owncloud

Server Build Continued

Create admin user

Connect to DB
DB clouddbuser
DB Ist1h1s0k?
DB clouddb
localhost

Log in click around.

Demonstrate what happens without encryption.

ls -ltra /var/www/html/owncloud/data/mattd/files/

Create a file named test
Upload test

less /var/www/html/owncloud/data/mattd/files/test

Enable encryption!

Go to apps and enable encryption
Go back to admin and you will see that you need to logout.
Logout AND log back in to encrypt files.
Go to admin page to setup recovery key.

Now check the file.
less /var/www/html/owncloud/data/mattd/files/

Add apps from Owncloud?
https://apps.owncloud.com/?xsortmode=high

scp to server and unzip into: /var/www/html/owncloud/apps/
ls -ltra /var/www/html/owncloud/apps/
