Project CMS finished
I have been very busy for the last 3 months, for building a CMS management system for The Smith Group. It contains 14 websites and an admin CMS system.
The system is built from scratch in PHP MYSQL Javascript AJAX in a linux box.
Project management nightmare:
The requirement was not full established at the beginning of the project, and Project Manager went on vacation for 8 weeks. During the 8 weeks, I hard coded all the CMS systems, and based on the website new template he gave me. I have all the functions coded, website integrated, modified, etc etc. But when he got back, everything I did was not he wanted. From experience, it highly depends on his input on this project during the process of building the system. Now that he is back, 3 weeks after, all the functions, website layout, hyper links, etc etc are changed. Until now, he still wants to change functions, although these functions are already been modified in the previous 3 weeks. But anyway, the project is getting to an end. I will responsible for future changes.
From this example, also as per project management studies, how important it is to have a fully established and fully understand requirement for any given project!!!
I learned from experience, especially this experience, that to work on a project or to start a new project, requirement study and feasibility study is very important, and also have the requirements and scale well established before the start is the key to have a successful project.
Although this Smith CMS project is finished, it has extended for an extra 2 weeks in an established 9 weeks project schedule, which is about 1/5 times more. It is a successful project based on customer satisfaction, functionality, and so on.

We are moving
ICN Technologies is moving office to the beautiful side of town, Mawson Lakes. To view the late, it’s much joyful to work, and more motivation to work harder as we wondered.
Anyway, the moving is about to commence on the 15th of May, 2008.

NAS File Server – HDD LAN Enclosure
NAS (Network Attached Storage) is rated the most looking forwarded technology by The PC Authorities. ICN Technologies is pleased to introducing the very compact NAS HDD LAN Enclosure.
This unit support up to 1TB Hard Drive, and works as FTP, NFS, SAMBA server, depends on configuration, all services can run at the same time.
Here is a picture of the unit in action.
Install Apache2.2 with ssl in FREEBSD
Getting Apache installed to get a web server running!
Installing Apache2.2
Make sure you update ports and then run the following commands:
# cd /usr/ports/www/apache22
# make install clean
That will install apache2.2
Configuring apache2
Lets edit the httpd.conf file:
# vi /usr/local/etc/apache22/httpd.conf
Scroll down and change the following settings. The optional settings I will put OPTIONAL before the setting:
OPTIONAL: Listen 80 – You can change this default option if you have more than one apache server running on your network
OPTIONAL: User www – Changes what user apache runs as
OPTIONAL: Group www – Changes what group apache runs as
ServerAdmin <!– var prefix = ‘ma’ + ‘il’ + ‘to’; var path = ‘hr’ + ‘ef’ + ‘=’; var addy46099 = ‘you’ + ‘@’; addy46099 = addy46099 + ‘example’ + ‘.’ + ‘com’; document.write( ” ); document.write( addy46099 ); document.write( ” ); //–> you@example.com This email address is being protected from spam bots, you need Javascript enabled to view it – change <!– var prefix = ‘ma’ + ‘il’ + ‘to’; var path = ‘hr’ + ‘ef’ + ‘=’; var addy46099 = ‘you’ + ‘@’; addy46099 = addy46099 + ‘example’ + ‘.’ + ‘com’; document.write( ” ); document.write( addy46099 ); document.write( ” ); //–> you@example.com This email address is being protected from spam bots, you need Javascript enabled to view it to your email address.
OPTIONAL: DocumentRoot “/stuff/www” – I don’t usually use the default path. I put my www documents on a seperate drive.
OPTIONAL: Directory “/stuff/www” – Change this to the same path as DocumentRoot (See above)
OPTIONAL: DirectoryIndex index.html index.html.var – add any pages you would use. For instance, add index.php if you use php pages
OPTIONAL: #CustomLog /var/log/httpd-access.log combined – I usually leave this commented unless you want to use this to track users looking at your site
OPTIONAL: ScriptAlias /cgi-bin/ “/usr/local/www/cgi-bin/” – change this to your cgi-bin path
OPTIONAL: Directory “/usr/local/www/cgi-bin”> – change this to the same path as ScriptAlias /cgi-bin above
Now lets tell apache to start:
# apachectl start
and hit Enter on your keyboard
We now need to tell Apache to run on startup. Please run the following command:
# echo ‘apache22_enable=”YES”‘ >> /etc/rc.conf
If you get no errors, apache should be running. Look at the page by opening a browser to http://localhost or replace localhost with the IP or the actual hostname of the box. If you went with the DocumentRoot defaults, You will see an apache test page until you get your site up and going. If you are behind a router or firewall, make sure you forward the apache port (Port 80) to the FreeBSD box otherwise you won’t be able to get there from here.
Configuring SSL
Let’s get SSL Configured and Installed:
(FROM http://www.bsdguides.org/guides/freebsd/webserver/apache_ssl_php_mysql.php)
# mkdir /usr/local/etc/apache22/ssl.key
# mkdir /usr/local/etc/apache22/ssl.crt
# chmod 0700 /usr/local/etc/apache22/ssl.key
# chmod 0700 /usr/local/etc/apache22/ssl.crt
Create Certificate
Now, you need to understand that one server can hold multiple certificates, but only one per listening IP address. So, if your server is listening on one IP address, you can only have one certificate for the server. Follow me so far? All of your virtual domains can share the same certificate, but clients will get warning prompts when they connect to a secure site where the certificate does not match the domain name. If your server is listening on multiple IP addresses, your virtual hosts have to be IP-based — not name-based. This is something to consider when creating your certificate.
Change to your root dir by typing in the following command. We want to save this configuration there as a backup.
# cd /root
# openssl genrsa -des3 -out server.key 1024
You will now be prompted to enter in a password. Write this down as you will need it later. We need to make a Certificate Signing Request (CSR):
# openssl req -new -key server.key -out server.csr
Enter your password when it asks for it. Make sure you enter your FQDN for the “Common Name” portion.
Self-signing your Certificate
You could always pay money to Verisign or Thawte for this but it costs $$$. Here is the way to do it:
# openssl x509 -req -days 365 -in /root/server.csr -signkey /root/server.key -out /root/server.crt
Now your cert is good for 365 days. If you want to make it longer, go right ahead and do so
If you would like more information about SSL Certs, go to http://httpd.apache.org/docs-2.0/ssl/ssl_faq.html#aboutcerts
Now we need to copy the certs to the right place:
# cp /root/server.key /usr/local/etc/apache22/ssl.key/
# cp /root/server.crt /usr/local/etc/apache22/ssl.crt/
Now to give them the right permissions as well:
# chmod 0400 /usr/local/etc/apache22/ssl.key/server.key
# chmod 0400 /usr/local/etc/apache22/ssl.crt/server.crt
We will now want to copy the default httpd-ssl.conf from the extras folder to the Includes folder:
# cd /usr/local/etc/apache22/extra
# vi httpd-ssl.conf
Now modify the following:
DocumentRoot “/usr/local/www/data” – Change the path to your httpd.conf document root.
ServerName www.example.com:443 – Change www.example.com to your domain name.
ServerAdmin <!– var prefix = ‘ma’ + ‘il’ + ‘to’; var path = ‘hr’ + ‘ef’ + ‘=’; var addy46099 = ‘you’ + ‘@’; addy46099 = addy46099 + ‘example’ + ‘.’ + ‘com’; document.write( ” ); document.write( addy46099 ); document.write( ” ); //–> you@example.com This email address is being protected from spam bots, you need Javascript enabled to view it Change this to your email address
ErrorLog /var/log/httpd-error.log – You can leave this or comment it out.
TransferLog /var/log/httpd-access.log – You can leave this or comment it out.
Now run the following:
# apachectl stop
# apachectl start
The start means it will start in ssl mode to serve both http:// and https:// addresses. This used to be apachectl sslstart but that command has been depreciated.
The URL below includes instructions on how to remove the pass phrase prompt when apache starts
http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html#removepassphrase
Configuring php for Apache
This section is pretty easy. Just run the following:
# cd /usr/ports/lang/php5
# make config
Make sure the box is checked that says Apache. If it isisn’t, put the cursor over it and then hit the Space Bar. Hit Tab and then hit Enter.
Then run the following to upgrade php5 to support Apache2.2
# make install clean
Next, we want to configure apache to use php5.
# vi /usr/local/etc/apache22/httpd.conf
and look for the first AddType section and add this to next line below the AddType section
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
Next go to DirectoryIndex and make sure index.php is part of it like so:
DirectoryIndex index.php index.html
With Apache2.2 it now wants to load an Accept Filter. If you don’t load the following module on startup, You will get an error everytime you start apache. Run the following command:
# echo ‘accf_http_load=”YES”‘ >> /boot/loader.conf
Now rather than rebooting the box, we can load the module manually by running:
# kldload accf_http
and then if you start Apache, You won’t get that error.
Now run the following command to start apache.
# apachectl stop
# apachectl start
You will now have apache with SSL and PHP support!
