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):

sudo tasksel install lamp-server

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:

sudo apt-get install postfix
sudo dpkg-reconfigure postfix

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:

sudo gedit /etc/mysql/my.cnf
query_cache_limit       = 4M
query_cache_size        = 64M

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.

sudo gedit /etc/php5/apache2/php.ini

Change the following line:

memory_limit = 32M

to:

memory_limit = 128M

Installing Pear and PECL Packages

We need to install a few Pear and PECL packages for PHP. For the Pear packages you can do:

sudo apt-get install php-pear php-apc  php-mdb2 php-mdb2-driver-mysql 
sudo pear install text_password console_getopt

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:

sudo gedit /etc/php5/conf.d/apc.ini

Then add the following lines:

apc.shm_size=100
apc.slam_defense = Off

See slam defense and this.

You'll need to restart Apache after making this change.

sudo /etc/init.d/apache2 restart

There are two optional packages you may wish to install:

sudo apt-get install php5-gd php5-tidy

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)

sudo apt-get install libmagic-dev php5-dev
sudo pecl install Fileinfo

If this doesn't work, you can also try:

sudo pear install pecl/Fileinfo
echo extension=fileinfo.so | sudo tee /etc/php5/apache2/conf.d/fileinfo.ini

Configuring Apache Web Server

You will see later we are using the apache rewrite module. To enable the module:

sudo a2enmod rewrite

Now we need to make sure we can use the .htaccess file.

sudo gedit /etc/apache2/sites-available/default

Change:

<Directory /var/www/>
	Options Indexes FollowSymLinks MultiViews
	AllowOverride None
	Order allow,deny
	allow from all
</Directory>

to:

<Directory /var/www/>
	Options Indexes FollowSymLinks MultiViews
	AllowOverride All
	Order allow,deny
	allow from all
</Directory>

Save and quit.

Let us restart the Apache webserver using:

sudo /etc/init.d/apache2 restart

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:

sudo mkdir -p /var/lib/iHRIS/lib/4.0.7
cd /var/lib/iHRIS/lib/4.0.7
sudo wget http://launchpad.net/ihris-manage/4.0/4.0.6/+download/ihris-manage-full-4_0_7.tar.bz2
sudo tar -xjf ihris-manage-full-4_0_7.tar.bz2

Downloading the Lesotho Customizations of iHRIS Manage

To download the software you enter these commands:

sudo apt-get install bzr
sudo mkdir -p /var/lib/iHRIS/sites
sudo chown `whoami`:`whoami` /var/lib/iHRIS/sites
cd /var/lib/iHRIS/sites
bzr branch lp:~intrahealth+informatics/ihris-manage/SL-sample
cd /var/lib/iHRIS/sites/SL-sample
bzr bind lp:~intrahealth+informatics/ihris-manage/SL-sample

Setting Up The Site

Database Setup

To create the needed database you can do:

mysql -u root -p

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:

CREATE DATABASE manage_SL;
GRANT ALL PRIVILEGES ON manage_SL.* TO ihris@localhost identified by 'manage';
SET GLOBAL log_bin_trust_function_creators = 1;
exit

If you are having trouble creating routines see this.

Making the Site Available

We make iHRIS Manage site available via the webserver:

sudo ln -s /var/lib/iHRIS/sites/SL-sample/pages /var/www/ihris-SL

Finishing Up

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

http://localhost/ihris-SL

and wait for the site to initialize itself. Congratulations! You may log in as the i2ce_admin with the password manage

Updating Customizations

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

cd /var/lib/iHRIS/site/SL-sample
bzr update
