Linux (RedHat-Fedora) Installation
Getting Ready
Here are instructions for installing the iHRIS Suite on an Linux (RedHat or Fedora) system. If you need help installing a RedHat distribution, visit:
The following steps assume you have root-level access to your Linux machine. Root-level access is achieved by any of the following steps
- Login to your server directly as the root user.
- Use "su" at the command prompt to switch to the root user.
- Prepend the "sudo" command to each command listed here to execute as root.
First, if your Linux installation includes SELinux, disable it using by modifying /etc/sysconfig/selinux to read:
SELINUX=disabled
Now, install a Lamp server.
yum install httpd mysql-server php php-devel php-mysql php-xml
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.
Please ensure your system can send email properly before continuing. RedHat and Fedora typically will have a configured version of sendmail installed by default.
Installing Pear and PECL Packages
We need to install a few Pear and PECL packages for PHP. For the Pear packages you can do:
yum install php-pear php-pecl-apc pear install MDB2 MDB2#mysql text_password console_getopt
During certain activities like installation and upgrades you may need more memory than APC uses by default. To increase the memory limit, edit /etc/php.d/php.ini and change:
apc.shm_size=32
to
apc.shm_size=100
There are two optional packages you may wish to install:
yum install php-gd php-tidy
These packages are used to for inserting images into PDF output of reports and for exporting XML files in a nicely formatted manner.
The pecl package FileInfo is used to verify the validity of file types used for uploading (e.g. for uploaded images or docuemnts). You can install this with the following commands:
yum install file-devel pecl install Fileinfo echo extension=fileinfo.so >> /etc/php.ini
After installing these supplemental packages, be sure to restart apache with the following command:
apachectl restart
Database Setup
Manual Setup
To create the needed database you can do:
/etc/init.d/mysqld start mysql -u root mysql> CREATE DATABASE ihris_manage; mysql> GRANT ALL PRIVILEGES ON ihris_manage.* TO ihris_manage@localhost identified by 'PASS';
where you substitute PASS with something appropriate. If you want to install iHRIS Qualify (or iHRIS Plan) just replace everywhere you see manage with qualify (or plan).
In version 4.0.1 of iHRIS we create mysql functions. If you are having trouble creating routines see this.
On Fedora systems, you'll also need to execute these commands to ensure database connectivity functions correctly:
ln -s /var/lib/mysql/mysql.sock /var/run/mysqld/mysqld.sock
Downloading the Software
To download the software you enter these commands:
cd /var/lib mkdir iHRIS cd /var/lib/iHRIS mkdir 4.0.0 ln -s 4.0.0 4.0 ln -s 4.0 current cd /var/lib/iHRIS/4.0.0 wget http://launchpad.net/ihris-manage/4.0/4.0.0/+download/ihris-manage-full-4_0_0.tar.bz2 tar -xjf ihris-manage-full-4_0_0.tar.bz2
Creating a Site Configuration File
We are going to start by modifying the BLANK site for iHRIS Manage. If you wish to install iHRIS Qualify or iHRIS Plan, you can follow the same instructions below but change manage to qualify or plan. To copy the BLANK site:
cd /var/lib/iHRIS/ mkdir sites cp -R /var/lib/iHRIS/current/ihris-manage/sites/blank /var/lib/iHRIS/sites/manage mv /var/lib/iHRIS/sites/manage/iHRIS-Manage-BLANK.xml /var/lib/iHRIS/sites/manage/iHRIS-Manage-Site.xml
We now need to edit the site configuration file:
vim /var/lib/iHRIS/sites/manage/iHRIS-Manage-Site.xml
by changing:
<path name='modules'>
<value>./modules</value>
<!-- If this site module is not installed under the iHRIS Manage
file structure, then remember to include a path to the rest of
the modules here.
e.g. <value>..</value>
-->
</path>
to:
<path name='modules'>
<value>./modules</value>
<value>/var/lib/iHRIS/current</value>
</path>
You may choose to change the email address feedback is sent to by changing:
<configuration name='email' path='to' values='single'>
<displayName>Email Address</displayName>
<value>BLANK</value>
</configuration>
to:
<configuration name='email' path='to' values='single'>
<displayName>Email Address</displayName>
<value>my_email@somewhere.com</value>
</configuration>
You may also choose to change BLANK everywhere with your organization's name. For best results, please choose one word, possilby with a dash, such as Sample, MOH, or MOH-Taifeki. To make this change, hit the replace icon, fill in blank under Search for and MOH-Taifeki under Replace With, then hit replace all.
Making the Site Available
We will now edit the configuration to let the site know about the database user and options:
vim /var/lib/iHRIS/sites/manage/pages/config.values.php
We now need to uncomment and set the value of a few variables. They are:
| Variable Name | Value |
|---|---|
| $i2ce_site_i2ce_path | /var/lib/iHRIS/current/I2CE |
| $i2ce_site_database | ihris_manage |
| $i2ce_site_database_user | ihris_manage |
| $i2ce_site_database_password | YYYYY (the password you set above) |
| $i2ce_site_module_config | /var/lib/iHRIS/sites/manage/iHRIS-Manage-Site.xml |
Save and quit.
Finally, we make iHRIS Manage site we just created available via the webserver:
ln -s /var/lib/iHRIS/sites/manage/pages /var/www/html/manage cp /var/www/html/manage/htaccess.TEMPLATE /var/www/html/manage/.htaccess vim /var/www/html/manage/.htaccess
We need to look for the line RewriteBase and change it to the web directory we want to use we are using, /manage. You may now save and quit. You will see we are using the apache rewrite module. To enable the module:
a2enmod rewrite
Now we need to make sure we can use the .htaccess file.
vim /etc/httpd/conf/httpd.conf
Change:
<Directory /var/www/html/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
to:
<Directory /var/www/html>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
Save and quit.
Finishing up
Let us restart the Apache webserver using:
/etc/init.d/httpd restart
Now we are ready to begin the site installation. Simply browse to:
and wait for the site to initalize itself. Congratulations! You may log in as the administrator with the default password administator.
