Getting Ready

Here are instructions for installing the iHRIS Suite on an Linux (Ubuntu) system. If you need help installing Ubuntu you may want to take a look at these directions for installing a Server or a Desktop system.

Note: Unless specifically mentioned, all the commands below are run using a terminal. You can start this in Ubuntu by going to Applications -> Accessories -> Terminal. Any time a command begins with sudo it will prompt for your password because this will be run with administrative privileges. When you run sudo multiple times, only the first time will ask for your password.

Note: Some installation commands will prompt for inputs in the terminal window, usually with a blue background. The mouse doesn't work to click on options here. You can use Tab to move between options and the space bar to check or uncheck selections.

Note: Some commands will launch the gedit file editor. Look at the documentation if you need additional help.

We begin by install a Lamp server (You can find more help here): <source lang="bash"> sudo tasksel install lamp-server </source> If you have never used mysql on your system, you will be asked to set the 'root' password for mysql. We will refer to this password as XXXXX below.

Important: Make sure your email system is correctly configured. Under a default Ubuntu installation, you can do this with one of two commands: <source lang="bash"> sudo apt-get install postfix sudo dpkg-reconfigure postfix </source>

Follow the on-screen instructions to set up email on your system. For additional help with installing Postfix, look at these instructions. On Debian systems, the same commands can be used, but exim4 is the default MTA instead of postfix

If you are using another Linux distribution, make sure your system can send email properly before continuing.

Configuring MYSQL

Make sure you have in /etc/mysql/my.cnf the following values set: <source lang="bash"> sudo gedit /etc/mysql/my.cnf </source> <source lang="ini"> query_cache_limit = 4M query_cache_size = 64M </source> It appears that they were reduced with Karmic

Configuring PHP

Next, you'll need to increase the memory limit for PHP. You can do this by editing the /etc/php5/apache2/php.ini. <source lang="bash"> sudo gedit /etc/php5/apache2/php.ini </source>

Change the following line: <source lang="ini"> memory_limit = 32M </source> to: <source lang="ini"> memory_limit = 128M </source>

Installing Pear and PECL Packages

We need to install a few Pear and PECL packages for PHP. For the Pear packages you can do: <source lang="bash"> sudo apt-get install php-pear php-apc php-mdb2 php-mdb2-driver-mysql sudo pear install text_password console_getopt </source>

During certain activities like installation and upgrades you may need more memory than APC uses by default. The php-apc package should have installed a file in /etc/php5/conf.d/apc.ini. Edit this file:

<source lang="bash"> sudo gedit /etc/php5/conf.d/apc.ini </source>

Then add the following lines:

<source lang="ini"> apc.shm_size=100 apc.slam_defense = Off </source> See slam defense and this.

You'll need to restart Apache after making this change. <source lang="bash"> sudo /etc/init.d/apache2 restart </source>

There are two optional packages you may wish to install: <source lang="bash"> sudo apt-get install php5-gd php5-tidy </source> which are used to for inserting images into PDF output of reports and for exporting XML files in a nicely formatted manner

FileInfo

Note: If you're running Ubuntu 10.4 (Lucid Lynx) then you do not need to install Fileinfo.

The pecl package FileInfo is used to verify the validity of file types used for uploading (e.g. for uploaded images or documents) <source lang="bash"> sudo apt-get install libmagic-dev php5-dev sudo pecl install Fileinfo </source> If this doesn't work, you can also try: <source lang="bash"> sudo pear install pecl/Fileinfo echo extension=fileinfo.so | sudo tee /etc/php5/apache2/conf.d/fileinfo.ini </source>

Configuring Apache Web Server

You will see later we are using the apache rewrite module. To enable the module: <source lang="bash"> sudo a2enmod rewrite </source> Now we need to make sure we can use the .htaccess file. <source lang="bash"> sudo gedit /etc/apache2/sites-available/default </source> Change: <source lang="apache"> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </source> to: <source lang="apache"> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> </source> Save and quit.

Let us restart the Apache webserver using: <source lang="bash"> sudo /etc/init.d/apache2 restart </source>

Ubunutu 10.4 Lucid

If you are using Lucid 10.4 Ubuntu, make sure that you following these important instructions

Downloading the Main iHRIS Manage Software

To download the software you enter these commands: <source lang="bash"> sudo mkdir -p /var/lib/iHRIS/lib/4.0.10 cd /var/lib/iHRIS/lib/4.0.10 sudo wget http://launchpad.net/i2ce/4.0/4.0.10/+download/ihris-suite-4_0_10.tar.bz2 sudo tar -xjf ihris-suite-4_0_10.tar.bz2 </source>

Downloading the NC of iHRIS Qualify

Launchpad First Steps

First you should create an account on Launchpad if you not have already done so. We will refer to this account as LAUNCHPAD_USER.

Since we will want to contribute to the code, we will need to create a ssh public key on your Ubuntu machine to add to Launchpad:

sudo apt-get install openssh-client
ssh-keygen -t rsa

When prompted, press Enter to accept the default file name for your key. Next, enter then confirm a password to protect your SSH key.

Your key pair is now stored in ~/.ssh/id_rsa.pub (public key) and ~/.ssh/id_rsa (private key). Now you need to upload the public portion of your SSH key to Launchpad. To do this, open in your web browser:

https://www.launchpad.net/~LAUNCHPAD_USER

You will see a place that says SSH Keys with an exclamation point (!) in a yellow circle next to it. Click on the (!) scroll down until you see Add an SSH Key and a text box. We will paste our public key into this text box. To do so type in a terminal:

gedit ~/.ssh/id_rsa.pub

you can now copy the contents of gedit (the public key) into the text box in the web browser. Now simply click on the button Import Public Key

For every computer/account that you use you will need to repeat these steps to create and import a public key.

Bazaar First Steps

First we need to make sure the Bazaaar (bzr) version control software is installed:

 sudo apt-get install bzr bzrtools

You may wish to read the five minute tutorial at this point. You should also let bzr know how you are:

 bzr whoami "Your Name <your@email.add.ress>"

Getting the NC Customizations

To download the software you enter these commands: <source lang="bash"> sudo apt-get install bzr sudo mkdir -p /var/lib/iHRIS/NC sudo chown `whoami`:`whoami` /var/lib/iHRIS/NC cd /var/lib/iHRIS/NC bzr branch lp:~intraheath+informatics/+junk/NC_4_0 4.0 cd /var/lib/iHRIS/NC/4.0 bzr bind lp:~intraheath+informatics/+junk/NC_4_0 </source>

Setting up the NC Site and Database

Database Setup

To create the needed database you can do: <source lang="bash"> mysql -u root -p </source> Enter the password you set above (XXXXX) for MySQL. You will now be able to send commands to MySQL and the prompt should always begin with 'mysql> '. Type these commands: <source lang="mysql"> CREATE DATABASE qualify_NC_4_0; GRANT ALL PRIVILEGES ON qualify_NC_4_0.* TO ihris@localhost identified by 'PASSWORD'; SET GLOBAL log_bin_trust_function_creators = 1; exit </source>

Substitute PASSWORD with something appropriate.


If you are having trouble creating routines see this.

Setting the Password

Now we need to set the password PASSWORD in the main configuration file. Run the commands: <source lang="bash"> mkdir -p /var/lib/iHRIS/NC/4.0/pages/local/ cp /var/lib/iHRIS/NC/4.0/pages/config.values.php /var/lib/iHRIS/NC/4.0/pages/local/config.values.php gedit /var/lib/iHRIS/NC/4.0/pages/local/config.values.php </source> and the PASSWORD in the following line to what you chose above: <source lang="php"> /**

* the dsn to connect to your database
*/

$i2ce_site_dsn = 'mysql://ihris:PASSWORD@localhost/qualify_NC_4_0' ; </source> Now Save and Quit.

Making the Site Available

We make iHRIS Manage site available via the webserver: <source lang="bash"> sudo ln -s /var/lib/iHRIS/NC/4.0/pages /var/www/NC </source>

Finishing Up

Now we are ready to begin the site installation. Simply browse to:

http://localhost/NC

and wait for the site to initialize itself. Congratulations! You may log in as the i2ce_admin with the password you used to connect to the database (YYYY that you set above).

Updating Customizations

To update the customizations from launchpad, ensure that port 22 is open on the server and do:

cd /var/lib/iHRIS/NC/4.0
bzr update
