Install Web Server Prerequisites¶

The myamiweb files are mostly php scripts that run at the web server. PHP, PHP-devel, gd, and fftw3 packages are required before installation of myamiweb and the mrc extension that handles the display of mrc files. Some of these packages may be found on the SuSE Linux DVD or included in common package repository. MySQL and the Apache Web Server can be downloaded from their respective websites.

Extra Packages for Enterprise Linux (EPEL)¶

• http://fedoraproject.org/wiki/EPEL

Install Supporting Packages¶

• Use the installation tools available for your linux distribution.
  For example, to install gd as php extension you may use
  

  CentOS> sudo yum install php-gd
  SuSE10.2 and above> zypper install php-gd
  

  
  Likewise, use the SuSE Linux YaST2 utility or zypper (openSuSE 10.2 and above) to install.
  An older list of required CENTOS rpms and instruction can be found in the Forum.

• Use the following table to find and install the prerequisite packages required for your distribution of linux:

Notes:

• RPM.pbone.net http://rpm.pbone.net/ provides a nice interface to search for module names on RPM based systems.
• GD is usually installed with php. If you find that you can only view images as png instead of jpg, it may be that you do not have gd jpeg support installed.
