Building and Testing PHP 7 under DragonFlyBSD 4.0.5

DragonFlyBSD 4.0.5 is waiting for me to test it 🙂 . I love it for several factors :

  • Size; its iso file is light in size (only 200MB + in bz2 form)
  • Learning curve; no need to learn much as I’m familiar with FreeBSD 🙂

As I already try PHP7 in FreeBSD before :

  1. Install PHP 7 akan phpng on FreeBSD 10
  2. Using PHP 7 with lighttpd on FreeBSD 10

I want to test it in DragonFly BSD with nginx as web server. This time  I use virtualbox and I try Hammer File system (make sure to have minimum 50 GB in disk size to usse Hammer File System in DragonFly BSD).


With 60 GB in disk size and 2GB memory allocated to this virtual machine I’ll try PHP 7.


Installation step is no different like before.



DHCP for sure 🙂


Reboot it and change boot order to get start with next steps :

Login via ssh

$ ssh [email protected] -p 2222
The authenticity of host ‘[]:2222 ([]:2222)’ can’t be established.
ECDSA key fingerprint is bd:e0:2a:f5:44:86:8d:5a:cd:2a:56:26:6a:f1:08:ce.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘[]:2222’ (ECDSA) to the list of known hosts.
Permission denied (publickey).

Ups, I forgot to configure ssh server first after as post installation step in DragonFly BSD.

Retry login

Well. Everything is on the right place 🙂

Lets get start install PHP 7 on DragonFly BSD :

# pkg update
Updating Avalon repository catalogue…
pkg: No address record
pkg: repository Avalon has no meta file, using default settings
pkg: No address record
pkg: Unable to update repository Avalon

Ups, looks like Avalon is not available at the moment.

My bad, I find out that nameserver is not work. Add Google public dns server.

# cat /etc/resolv.conf

Retry pkg update :

How to Permanently adjust screen brightness in Peppermint OS 5

My Dell laptop that running Peppermint OS 5 getting better each day. It can detect my wifi card and purge old one and that feature brought my brother in after frustrated for days with his Windows.

Another thing that I realize still need some work is brightness level. I must adjust brightness every time I restart my computer.

My current setting

$ cat /sys/class/backlight/acpi_video0/max_brightness
$ cat /sys/class/backlight/acpi_video0/actual_brightness

Yes, 6 is my preference level.

After look around I got the solution :

sudo add-apt-repository ppa:nrbrtx/sysvinit-backlight
sudo apt-get update
sudo apt-get install sysvinit-backlight

To check current brightness level using this script :

$ sudo service sysvinit-backlight status
Current brightness level for acpi_video0 = 6
Current brightness level for intel_backlight = 55

Well, good guess 🙂

Permanently save setting :

$ sudo service sysvinit-backlight stop
Saving acpi_video0 = 6
Saving intel_backlight = 55


Try restart my computer and it work perfectly 🙂

How to configure ssh access to virtualbox guest under NAT mode

Just quick note for my own 🙂

I need to ssh to my CentOS 6.6 box that run under Virtualbox with these steps :

1. NAT

Virtualbox will create private network using these address ( Just set eth0 configuration to DHCP and everything will be set.


2.  Port forwarding setup to port 2222

Click Setting -> Network -> Port Forwarding



3. Test ssh connection

ssh [email protected] -p 2222
The authenticity of host ‘[]:2222 ([]:2222)’ can’t be established.

Install minimal CentOS 6.6 with latest PHP and Percona Server 5.6

Being FreeBSD user for years make lazy to try something new 🙂 . CentOS and Ubuntu server are two distros that brought my attention via distrowatch. Today I have time to try latest CentOS 6 release (6.6) in my virtualbox and I love minimal installation and for that reason I choose CentOS 6.6 minimal iso (CentOS-6.6-x86_64-minimal.iso).

For target installation I choose LAMP and try to use latest component (PHP 5.6, MariaDB 10 or Percona server 5.6 and stock Apache (2.2) ).

Lets get start!

1. Install CentOS 6.6

Let default installation till finished.

2. Configure network

Everything located in /etc/sysconfig/network-scripts/ and every lan card installed in server you see using “ip a” command (remove ” sign).

In most case just change these properties :

  • ONBOOT -> yes

  • BOOTPROTO -> static (change to dhcp for dynamic address)

  • IPADDR -> enter ipv4 address

  • NETMASK -> enter subnet mask

  • GATEWAY -> enter ip4 address of your gateway

If you use vps, all these information available from control panel or check your email from provider.

# service network start

To restart network

3. Install basic stuff

# yum install nano bc wget lynx

4. Update yum

# yum update

5. Install Database

For MariaDB

# cd /etc/yum.repos.d/
# nano MariaDB.repo

Enter these lines :

# MariaDB 10.0 CentOS repository list – created 2015-04-14 06:56 UTC
name = MariaDB
baseurl =

save the file.

# yum install MariaDB-server MariaDB-client

For Percona Server

# yum install

# yum install Percona-Server-client-56 Percona-Server-server-56

6. Install PHP 5.6

# rpm -Uvh
# yum install php56w php56w-opcache php56w-mysql

7. Configuration

# chkconfig httpd --add
# chkconfig httpd on --level 235
# chkconfig mysql --add
# chkconfig mysql on --level 235

# iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT
# service iptables save

8. Run the service

# service httpd start
# service mysql start

Done. Basic LAMP server is successfully installed.

9. Create phpinfo page

# cd /var/www/html/
# echo "<?php echo phpinfo();?>" > info.php

10. Test

# lynx localhost/info.php

Install Latest Corona SDK on Linux Peppermint OS 5

I want to learn create game for my daughter since she like to play game in her Acer Tablet. I don’t know much about programming for mobile phone nor tablet but I’ll learn.

After dig for internet I decide to use Corona SDK but the problem came since I use Peppermint OS 5 that not supported.

I try Wine way and document the process here for my own reference. Might be useful for others.

Wine version

$ wine --version

Checking cmd command from wine

$ wine cmd
Wine CMD Version 5.1.2600 (1.6.2)


Volume in drive C has no label.
Volume Serial Number is 0000-0000

Directory of C:\

10/02/2015 12:03 <DIR> Program Files
14/01/2015 15:17 <DIR> Program Files (x86)

Great. Wine working fine.

Corona SDK

Download latest version for Windows

I got corona sdk 2014.2511


Install it

$ wine start CoronaSDK-2014.2511.msi

I got error message :

fixme:exec:SHELL_execute flags ignored: 0x00000100
fixme:storage:create_storagefile Storage share mode not implemented.
fixme:msi:ITERATE_CreateShortcuts poorly handled shortcut format, advertised shortcut

but I ignore it.

Follow the screen to get corona sdk installed.

Run Corona SDK

Menu -> Programs -> Corona SDK -> Corona Simulator


Try to compile (build for Android)

Got error message


Well, time for JDK.

Java Development Kit

According this docs I need JDK 7


Install this version also not work.


I skip this JDK problem as I still able to code and see it from simulator.

Well, time for continue learning 🙂

Update :

I use ZeroBrane Studio

$ wget -c 

$ chmod +x

$ ./
Verifying archive integrity… All good.
