Install OS4X on SLES11

Assumptions

• Your installation directory for OS4X is

/opt/os4x

• The web interfaces will be installed in the default document root directory of Apache:

/srv/www/htdocs

• The user running the installation is not "root", but "os4x" with limited permissions
• Firewalls and other security measurements are disabled or not installed. (If they are enabled, you have to change them on your own).

Add repository

For PHP functionality (network socket and Posix support) you need to add a new repository:

root$ zypper addrepo http://download.opensuse.org/repositories/server:/php/SLE_11/ PHP_SLE11

Install requried packages

Install all needed software (based on a minimal installation, many of these packages may already be installed):

root$ zypper install apache2-mod_php5 php-bz2 php-mysql php-xmlreader php-xsl php-zip php-zlib \
php5-sockets php5-posix mysql vim iputils zip samba-winbind yast2-kerberos-client glibc-locale glibc-i18ndata libxslt

Accept repository key (english)

After having added the new repository (see above), you will have to accept its key permanently (with selection "a" for "always"):

Change PHP configuration

Edit the file as root:

/etc/php5/apache2/php.ini

Change the following configuration values to these values:

upload_max_filesize = 128M
post_max_size = 128M

Start services

For the installation, you need Apache and MySQL up and running:

root$ service apache2 start
root$ service mysql start

Change the distribution

root$ chown os4x /srv/www/htdocs/
root$ mkdir /opt/os4x
root$ chown os4x /opt/os4x
root$ chgrp users /etc
root$ chmod g+w /etc
root$ chgrp users /var/log/apache2/

Running the installation script

Download and run the shell installer for OS4X:

os4x$ cd /tmp
os4x$ wget http://www.os4x.com/fileadmin/downloads/os4x3_full_pe_Linux-x86-64-MySQL.sh
os4x$ sh ./os4x3_full_pe_Linux-x86-64-MySQL.sh

Answer all question according to your needs (possible changed, see above), the defaults should match your environment if the default is used.

Securing distribution

The permissions, which have been changed above, can be reverted to increase security:

root$ chgrp root /etc
root$ chmod 755 /etc

Optionally, change the permissions of the Apache logs directory:

root$ chgrp root /var/log/apache2/

PAM authentification

If your OS4X Webaccess users need PAM authentification (i.e. Microsoft Active Directory), then you need to:

• change permissions of the binary:

/opt/os4x/bin/os4xclientd

Commands (executed as root):

root$ chown root /opt/os4x/bin/os4xclientd
root$ chmod +s /opt/os4x/bin/os4xclientd

• Configure PAM authentification support, as indicated here: PAM configuration for Windows Active Directory
