== Loading the accf_http module
On FreeBSD you must load the accf_module before you can start apache,
otherwise you are sure to get an httpready error.
# kldload accf_http
If it loaded successfully then it will not give any errors or output.
To have it load on boot
#ee /boot/loader.conf
accf_http_load="YES"
== Starting Apache
ก่อน restarting หรือ starting Apache ควรใช้คำสั่ง configtest เพื่อ check errors ใน httpd.conf
# apachectl configtest
Apache is controlled with apachectl
# apachectl start
# apachectl restart
# apachectl graceful
# apachectl stop
# /usr/local/etc/rc.d/apache22 onestart
# /usr/local/etc/rc.d/apache22 restart
== Test
# telnet localhost 80
# openssl s_client -connect localhost:443

FreeBSD: Mysql55-Server
------------------- เริ่มเลย ------
[1] ติดตั้ง
# cd /usr/ports/databases/mysql55-server
-------------------ติดตั้งแบบใช้ ตัวอักษร ภาษาไทย แบบ UTF8 ---------------
# make WITH_CHARSET=utf8 WITH_xCHARSET=all WITH_CALLATION=utf8_general_ci WITH_OPENSSL=yes BUILD_OPTIMIZED=yes WITH_FEDERATED=yes WITH_NDB=yes WITH_ARCHIVE=yes install clean
-------------------ติดตั้งแบบใช้ ตัวอักษร ภาษาไทย แบบ tis620--------------

************************************************************************
Remember to run mysql_upgrade (with the optional --datadir= flag)
the first time you start the MySQL server after an upgrade from an
earlier version.
************************** ผลการติดตั้ง ***********************************
This port has installed the following files which may act as network
servers and may therefore pose a remote security risk to the system.
/usr/local/libexec/mysqld
This port has installed the following startup scripts which may cause
these network services to be started at boot time.
/usr/local/etc/rc.d/mysql-server
If there are vulnerabilities in these programs there may be a security
risk to the system. FreeBSD makes no guarantee about the security of
ports included in the Ports Collection. Please type 'make deinstall'
to deinstall the port if this is a concern.
For more information, and contact details about the security
status of this software, see the following webpage:

1. ตรวจสอบ ว่าติดตั้ง Name Server แล้วหรือยัง (ปกติ จะมีติดตั้งมาพร้อมกับ OS)

กรณีที่ rebuild FreeBSD จาก source

Video: Component video
Definition of: component video
A video color format that maintains the three traditional TV video signals (YUV) in three separate channels. Component video provides a sharper image than composite video and S-video. See YUV, composite video and S-video.
Analog Component Video
With regard to TVs, DVD players, cable boxes, receivers and related consumer A/V equipment, component video generally refers to "analog" component video. The connection comprises three separate cables identified as Y, Pb and Pr (see YPbPr). Component video cables often come as five-wire sets: the three video and two more for left and right analog audio.
Digital Component Video
Component video may also refer to "digital" component video (YCbCr), which is the norm for videotape formats such as MiniDV, DV and Digital Betacam. The connection uses one cable, typically FireWire or SDI, and is natively supported by many nonlinear video editing programs (NLEs). Digital component video is also carried over HDMI cables, but to avoid confusion, the term "digital" is used to refer to HDMI signals, not "digital component." See YCbCr and chroma subsampling.
RGB: Digital or Analog
Sometimes, component video refers to RGB signals rather than YUV. It may refer to "digital" RGB, which is the native graphics format in the computer, and it is supported by all nonlinear video editing programs (NLEs).
Component video may also refer to "analog" RGB, especially with regard to a three-cable RGB attachment to a studio monitor or high-end video camera. See YUV.

Video:Color Space: YCbCr
Definition of: YCbCr
One of two primary color spaces used to represent digital component video (the other is RGB). The difference between YCbCr and RGB is that YCbCr represents color as brightness and two color difference signals, while RGB represents color as red, green and blue. In YCbCr, the Y is the brightness (luma), Cb is blue minus luma (B-Y) and Cr is red minus luma (R-Y). See component video.
YCbCr Is Digital
MPEG compression, which is used in DVDs, digital TV and Video CDs, is coded in YCbCr, and digital camcorders (MiniDV, DV, Digital Betacam, etc.) output YCbCr over a digital link such as FireWire or SDI. The ITU-R BT.601 international standard for digital video defines both YCbCr and RGB color spaces. See chroma subsampling.
YPbPr Is Analog
YPbPr is the analog counterpart of YCbCr. It uses three cables for connection, whereas YCbCr uses only a single cable (see YPbPr). See YUV, YUV/RGB conversion formulas and ITU-R BT.601.

Video:Color space: YPbPr Advantages
YPbPr Advantages
YPbPr is a color space encoding scheme that was developed to save on cable bandwidth requirements while separating the signal enough to provide a quality image. S-Video and composite video mix the signals together by means of electronic multiplexing, however, more often than not the signal is degraded at the display end as the display is not 100% able to separate the signals. It is possible for their multiplexed counterparts to interfere with each other (see Dot crawl). Signals that use YPbPr, like component video, offer enough separation of the signals that no multiplexing is needed, so the quality of the extracted image is generally near identical to the signal before encoding. Though not necessarily an advantage to YPbPr, component video which uses YPbPr was the only one out of the other two common analog cable standards (composite and s-video) to be able to transfer non-interlaced video and at the same time able to transfer resolutions higher than 480i/p.
Definition of: YPbPr
The designation for analog component video signals. The "Y," "Pb" and "Pr" are sets of three inputs or outputs on better video equipment and TVs. The three cables used in a YPbPr connection represent higher quality than the single-wire composite cable commonly used to hook up video equipment, because the brightness and color components of the signal are maintained separately. The YPbPr signals are derived from the red, green and blue (RGB) colors captured by a scanner or digital camera, and RGB is converted into brightness and two color difference signals (B-Y and R-Y) for TV/video. See component video.
YPbPr and YCbCr
YPbPr component video is the analog counterpart of digital component video, which is YCbCr. Whereas YPbPr uses three cables between video equipment, YCbCr uses a single cable. See Y (B-Y) (R-Y), YCbCr, YUV, YUV/RGB conversion formulas and color space.
