Steps (see details below) :

In J:\awww\apl\dev1\zz\zz30GB\dev1_zinstalac_dok\linux\1_virtualbox :

install vbox : 2click VirtualBox-5.1.26-117224-Win.exe as admin (?)
2click Oracle_VM_VirtualBox_Extension_Pack-5.1.26-117224.vbox-extpack
install oralin_7_3_V834394-01.iso and start oralin73 in vbox
install Guest Additions for Linux guest oralin73: Devices ->Guest add.
Outputs: Uncompress.VirtualBox 5.1.26 Guest Additions for Linux.....

see http://goto-adf.blogspot.hr/2014/11/install-oracle-xe-on-oracle-linux-7.html

WHERE ARE INSTALLED :
C:\Program Files\Oracle\VirtualBox - installed VirtualBox, .iso for add ons mount in Devices ->Guest add
C:\Users\ss\VirtualBox VMs - virtual machines images: oralinux, centos, ubuntu...
Snapshot folder is C:\Users\ss\VirtualBox VMs\oralin73\Snapshots

1. Install Oracle VirtualBox-6.0.6-130049-Win.exe

on Windows 10 64 bit, MAY 2019.

Why vbox ? Before larger installations we make snapshot to return to (any previos) state-snapshot before (failed) installation. Acronis disk images are much larger and slower. Learning is simplest-fastest with virtualization. Vagrant is second step after learned virtualization described here.

Download Oracle VM VirtualBox OR https://www.virtualbox.org/wiki/Downloads
New Wizzard (automatic settings GUI) : Click "New" in vbox main screen, Choose a name for your VM eg ora11gxefedora, J:\vbox\VMs
select type of OS (operating system) Linux, version Fedora (64 bit)
Select Memory size eg 4096 + 1024= 5120 MB and click Next
Create a virtual hard disk now, expert mode VDI (VirtualBox Disk Image), Dinamically allocated, ora11gxefedora 64 GB (8 GB for swap - required by Oracle 11g DB)
New Wizzard re-directs you back to vbox main screen.
Settings -> General -> Advanced -> Enable Shared Clippboard and Drag-drop both bidirectional
Snapshot folder is J:\vbox\VMs\ora11gxefedora\Snapshots
Settings -> System -> Processor -> 2 CPU (2 for Win 10 64 bit)
Settings -> Display -> Screen -> 128 MB
Settings -> Display -> Screen -> Enable 3D acceleration

Settings -> Network -> Adapter 1
-> Atached to: -> Bridged adapter (my is cable, Realtek PCIe GBE on
Gigabyte Z68AP-D3, Intel Core i5 2500K, 16 GB DDR3 - recomended. Minimum is half this CPU and half mem. but slow.
->Promiscuous Mode: Allow all

Settings -> Shared folders -> Add -> Folder path and name, eg J:\awww\www, name: fwphp
J:\awww\apl\dev1\zz\zz30GB\dev1_zinstalac_dok\linux\2_oralinux, name: 2_oralinux.
My virt. Apache site doc.root on Win.10 is J:\awww\apl\dev1 Auto-mount check box for all Shared folders.
Settings -> Storage -> IDE controller -> Click on Empty CD icon.
On screen right side click on CD image icon for the CD/DVD drive and click on the �Choose a virtual CD/DVD disk file...� -> Find ISO eg
L:\_ISO\_ISO\Fedora-Workstation-Live-x86_64-30-1.2.iso 1,9 GB
L:\1_instalac\1_instalirano\linux\2_oralinux\7_5\V975367-01.iso 4,3 GB

2. Install Oracle Fedora 30 guest OS on Win 10 64 bit Virtual Box

Download oralinux 7.3 from http://edelivery.oracle.com/linux
(http://www.oracle.com/technetwork/server-storage/linux/downloads/)

RIGHT CTRL TO FREE MOUSE !!

Select Virtual Machine ora11g that you just created. Click on the green Start icon on the top of vbox screen.
Select 'install Oracle linux 7.5' and click Enter key. Select language to use during the installation process.
Only ora Linux: Select Server with GUI. Minimal installation option is the installation without GUI.
Select :Add ons for selected environment and choose :
File and storage server
Java platform
Network filesystem client
Performance tools
Compatibility libraries
Development tools --- at least this
not !!! KDE desktop (installs also Gnome)
Select other buttons (keyboard if not english, partitioning...)
ethernet fwphp75 enp0s3 GENERAL: Automatic conn. to network ipv4 :
during installation you will see 2 red warnings indicating that the root password is not set and no users are created - create root account and user account
When system reboots, you will be directed to perform the initial setup,
click on the checkbox to accept the license agreement
and click on the Done button on the top left corner.
Click on the FINISH CONFIGURATION button to proceed.
do not forget to remove the tick at Boot Order 'CD/DVD'.

Oracle Linux 7.3 installation is finished.
I tested also Centos 7.3 and Mint 18.2 Cinnamon - do not work for me (after OS update - problems with booting same as with oralinux 7.3). To install DB 11g XE I ended withoralinux 7.3 - works better than 7.2.

2. Install VBoxGuestAdditions for guest Oracle Linux 7.3

After installing Linux on VirtualBox we need install VBoxGuestAdditions because of not working features :
Resolution is bad, Auto-Resize (rightctrl+f), Drag-Drop, Clipboard sharing

1. to install Guest Additions for Linux guest oralin73 :2 click :
L:\1_instalac\1_instalirano\linux\1_virtualbox\Oracle_VM_VirtualBox_Extension_Pack-6.0.6.vbox-extpack

2. remove Linux .iso from IDE controller
-> Start Linux > put vbox extension iso in IDE controller -> Devices ->Guest add. from vbox oralin73
Uncompressing VirtualBox 5.1.26 Guest Additions for Linux...

or less simple :
1- With vbox is installed :
C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso

2- start Orcle VM VirtualBox Manager -> click oralin73 Virtual Machine (powered off) -> click icon Settings
-> click Button 'Storage' and add a new 'Controller: IDE' for virtual DVD device, put iso above in it

3- now you can start Oracle Linux 7.3 and right click VBoxGuestAdditions icon -> open in terminal

\===>The gcc utility was not found.- error if I did not during linux installation selected development tools !!!!!!!

2-- su -
cd /home/ssoralin73/Disk1
1. rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
You must run '/etc/init.d/oracle-xe configure' as the root user to configure the database.

3-- 2. /etc/init.d/oracle-xe configure
This will configure on-boot properties of Oracle Database 11g Express
Edition. The following questions will determine whether
database should be starting upon system boot,
ports it will use,
passwords that will be used for database accounts.
Press ENTER to accept the defaults. Ctrl-C will abort.
Specify the HTTP port that will be used for Oracle Application Express [8080]:8085
Specify a port that will be used for the database listener [1521]:
Specify a password to be used for database accounts. Note that the same
password will be used for SYS and SYSTEM. Oracle recommends the use of different passwords for each database account. This can be done after
initial configuration:
Confirm the password:
Do you want Oracle Database 11g Express Edition to be started on boot (y/n) [y]:n
Starting Oracle Net Listener...Done
Configuring database...Done
Starting Oracle Database 11g Express Edition instance...Done
Installation completed successfully.

4-- Setting the Oracle Database XE Environment Variables
Log on with root permissions is not needed.
do not exit (from root user)
DB XE provides a script that sets environment variables :
cd /u01/app/oracle/product/11.2.0/xe/bin
gedit ./oracle_env.sh

Noting to change hear:
# /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe/bin
without /bin at end !!
export ORACLE_SID=XE
export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh`
export PATH=$ORACLE_HOME/bin/$PATH

see for NLS_LANG :
https://mikesmithers.wordpress.com/2015/03/01/installing-oracle-xe-on-centos/

run it :
3. ./oracle_env.sh

cd /etc/skel
ls -la | grep .bash_profile
Edit login or profile files so that these environment variables are set each time you log in or open a new shell :
gedit .bash_profile
enter the following line at end /etc/skel/.bash_profile :
4. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh

5-- Starting Oracle Database XE
To start the database manually, run this command as root user:
5. /etc/init.d/oracle-xe start or /etc/init.d/oracle-xe stop
or :
After you have installed Oracle Database XE, DB is up and running and you can start it if it is currently stopped:
Main menu (on Gnome)->Oracle Database 11g Express Edition
or 6. Applications->Other menu (on KDE),
and then click Start Database or Run SQL Command Line or...

Connect to the database using the user name SYSTEM, and supply the password that you created during configuration.
7. conn sys/ss141 as SYSDBA (system can not)

# gedit /etc/sysctl.conf
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.

# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.

# For more information, see sysctl.conf(5) and sysctl.d(5).

Oracle 11g XE on RHEL7

December 3, 2014 https://shi2wei3.github.io/posts/2014-12-03-oracle-11g-xe-on-rhel7.html
database

The prerequisite is i assume you already got a RHEL7 installed with GNOME3

Install oracle database 11gXE

it needs swap volume at least specify space 2 x memory (12 GB)

unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
cd Disk1
sudo rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm

Install sqlplus

su -
cd /home/ssoralin73
chmod 776 oracle-xe-11.2.0-1.0.x86_64.rpm.zip
unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip
unzip instantclient-sqlplus-linux.x64-12.2.0.1.0.zip
cd instantclient_12_2
ls -l
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so

To avoid error ee to see libsqlplus.so :
./sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
export LD_LIBRARY_PATH=$(pwd)

./sqlplus sys/ss141@localhost/XE as SYSDBA (system can not)
alter user hr account unlock;
alter user hr identified by hr;
grant CONNECT,DBA,RESOURCE to hr IDENTIFIED BY hr;
or grant create table to hr; ...

ALTER USER ANONYMOUS ACCOUNT UNLOCK;

# cd /home/ssoralin73/instantclient_12_2
# ./sqlplus hr/hr@localhost/XE

Alternative: rpm instantclient installation

put all three rpm in some tmp dir and :
ls *rpm
rpm -i *rpm
ls /usr/lib/oracle/12.1/client64/lib
ls /usr/lib/oracle/12.1/client64/bin - here is sqlplus dir
export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib
/usr/lib/oracle/12.1/client64/bin/sqlplus hr/hr@localhost/XE

or :

sudo rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
sudo rpm -ivh oracle-instantclient12.1-sqlplus-12.1.0.2.0-1.x86_64.rpm

If you got the error below, you need to add library path manually: sqlplus64: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/oracle/12.1/client64/lib/

which sqlplus

Step 1: Installing Remi Repository

ls /etc/yum.repos.d
epel.repo epel-testing.repo public-yum-ol7.repo

should be like this :
epel.repo public-yum-ol7.repo remi.repo
epel-testing.repo remi-php70.repo remi-safe.repo

https://rpms.remirepo.net/ and than your local, for me :
Slovenia http://ftp.arnes.si/mirrors/remi/

On RHEL/CentOS 7/oralin7 :

# yum update && yum install epel-release (if not installed)

# rpm -Uvh http://ftp.arnes.si/mirrors/remi/enterprise/remi-release-7.rpm
or
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

[root@oralin73 ~]# ls /etc/yum.repos.d
epel.repo epel-testing.repo public-yum-ol7.repo remi-php54.repo remi-php70.repo remi-php71.repo remi-php72.repo remi.repo remi-safe.repo

------ For RHEL 7 Only ------ not found on oracle linux 7
# subscription-manager repos --enable=rhel-7-server-optional-rpms

Step 2: Enabling the Remi Repository

common dependencies are in "remi-safe"

Now you make sure that remi repository is enabled and all set to install chosen PHP version,
to do this open remi.repo file and make sure the line set to enabled=1 as instructed below,
in order to install PHP 7.2

#gedit /etc/yum.repos.d/remi.repo

[remi]
name=Remi's RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/remi/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Now if you want to install PHP 5.5 or PHP 5.6, just set the line enabled=1 in sections
[remi-php55] and [remi-php56] to install as instructed below.

[remi-php55]
name=Remi's PHP 5.5 RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/php55/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/php55/mirror

Step 3: Installing Apache, MariaDB/MySQL, and PHP

To enable the MariaDB repository on RHEL/CentOS 7 distributions, create a file named
/etc/yum.repos.d/mariadb.repo with the following contents:
....

Step 4: Installing PHP Modules
------ On RHEL/CentOS 7/6 and Fedora 18-21 ------
yum --enablerepo=remi install php-pdo php-pecl-memcache php-pecl-memcached php-gd php-xml php-mbstring php-mcrypt php-pecl-apcu php-cli php-pear
also : php-mysqlnd php-pgsql php-pecl-mongo...

sudo yum install php yum above did not all needed !?

Step 5: Enable/Start Apache and MySQL/MariaDB
On SystemD � RHEL/CentOS 7 and Fedora 23-18

------ Enable Apache and MariaDB on Boot ------
# systemctl enable httpd
# systemctl enable mariadb

------ Start Apache and MariaDB ------
# systemctl start httpd
# systemctl start mariadb

yum --enablerepo=remi install php56-php-oci8.x86_64

Step 6: Verifying PHP 5.5 or 5.6

7. Enable Remote Connection to Apache HTTP Server (httpd)

-> Open Web server Port (80) on Iptables Firewall (as root user again)

1. CentOS/Red Hat (RHEL)

1. Edit /etc/sysconfig/iptables file:
gedit -w /etc/sysconfig/iptables

2. Add following INPUT rule:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

3. Restart Iptables Firewall:
service iptables restart ## OR ## /etc/init.d/iptables restart

3. Test remote connection
http://your.domain/test.php

8a. Install MySQL 5.5 using Yum

yum --enablerepo=remi install mysql mysql-server

service mysqld start

Execute mysql_secure_installation script and follow the wizard. It will prompt for root password.
To get temporary root password check /root/.mysql_secret file

/usr/bin/mysql_secure_installation

Autostart MySQL on boot :
chkconfig mysqld on

Login to MySQL using root access and try to create a dummy db,
root user password is in /root/.mysql_secret :
mysql -u root -p

Create a dummy database using following command.

mysql> create database dummydb;
Query OK, 1 row affected (0.01 sec)

8b. Install phpMyAdmin using EPEL repository

phpMyAdmin is a free open source web interface tool, used to manage your MySQL databases. By default phpMyAdmin is not found in CentOS official repositories, so install it using EPEL repository.

To install EPEL repository, follow the below link:

- [Install EPEL Repository On RHEL/CentOS/Scientific Linux 6]
(http://www.unixmen.com/install-epel-repository-rhel-centos-scientific-linux-6/ "Install EPEL Repository On RHEL/CentOS/Scientific Linux 6")

Now install phpMyAdmin

yum install phpmyadmin -y

**Configure phpMyAdmin**

gedit /etc/httpd/conf.d/phpMyAdmin.conf

Find and comment the whole / section as shown below:

[...]
Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin

<Directory /usr/share/phpMyAdmin/>

# <IfModule mod_authz_core.c>
# # Apache 2.4
# Require local
#
# <IfModule !mod_authz_core.c>
# # Apache 2.2
# Order Deny,Allow
# Deny from All
# Allow from 127.0.0.1
# Allow from ::1
#

[...]

Open �config.inc.php� file and change from �cookie� to �http� to change the authentication in phpMyAdmin:
cp /usr/share/phpMyAdmin/config.sample.inc.php /usr/share/phpMyAdmin/config.inc.php
gedit /usr/share/phpMyAdmin/config.inc.php
[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]

service httpd restart
http://server-ip-address/phpmyadmin/ access phpmyadmin console
Enter your MySQL username and password which you have given in previous steps (eg �root� and �centos�).

Now you will able to manage your MariaDB databases from phpMyAdmin web interface.

10. Install Redis cache on CentOS and Redhat

phpredis extension provides an API for communicating with the Redis key-value store (open source BSD licensed, in-memory data structure store used as database, cache and message broker).

wget http://download.redis.io/releases/redis-2.8.6.tar.gz
tar -zxvf redis-2.8.6.tar.gz
cd redis-2.8.6
make

Once you installed it without any error move two Redis files into the /usr/local/bin/ directory...

cd src
cp redis-server /usr/local/bin/
cp redis-cli /usr/local/bin/

Now time to move default init script and configuration file's.

cd utils/
cp redis_init_script /etc/init.d/redis
cd ..
cp redis.conf /etc/

After that edit the redis.conf file and make certain changes.

gedit /etc/redis.conf

* Set daemonize yes
* Set bind to loop back ip address[127.0.0.1]
* Set logfile /var/log/redis.log default set to /dev/null
* Set pidfile /var/run/redis.pid
* Set LogLevel to Debug to debug issue
* Set the number of databases on a per connection basis. The default value is 0
* Set maxmemory as per requirement.

Now download install and configure phpredis

git clone git://github.com/nicolasff/phpredis.git
cd phpredis
phpize
./configure
make && make install

gedit /etc/php.d/redis.ini
Add extensions redis.so in file:
extension=redis.so

service httpd restart

CentOS 7 minimal and GUI

https://snapcraft.io/docs/installing-snap-on-red-hat
Canonical https://www.canonical.com/ describes Snap as a universal Linux package which can work on any distribution.

Adding EPEL repository to RHEL >=7.6, less than 8

The EPEL repository can be added to a RHEL 7 system with the following command:

1. sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel--optional-rpms" --enable "rhel--extras-rpms"
sudo yum update

Installing snapd

With the EPEL repository added to your RHEL installation, install snapd package:

2. sudo yum install snapd

Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:

3. sudo systemctl enable --now snapd.socket

Created symlink from /etc/systemd/system/sockets.target.wants/snapd.socket to /usr/lib/systemd/system/snapd.socket
which snap
/usr/bin/snap
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:

4. sudo ln -s /usr/bin/snap /snap

sudo ln -s /var/lib/snapd/snap /snap

5. log out and back in again or restart your system** to ensure snap’s paths are updated correctly.

Snap is now installed and ready to go! If you're using a desktop, a great next step is to install the Snap Store app.
https://snapcraft.io/docs/installing-snap-store-app
sudo snap install snap-store

If you use a desktop environment, snaps can be more readily discovered, installed and managed from the Snap Store desktop app.
