h1. Possible Computer Set-up Configurations Computer(s) used for the whole Leginon system need to support five functions: # TEM/Camera control and data output (by python-side packages of Leginon system) *Note:* The computer attached to the microscope/camera is used for this function. Therefore, it is on a Windows computer. # General Leginon operation such as target selection and image processing (processing server of Leginon system) # Image data storage. # Other meta-data storage through MySQL database (by database server of Leginon system) # Web server (using PHP-side of Leginon system). *Important:* The MRC module that is used to load mrc formatted files to the web pages is not compiled on Windows. Therefore, this function must be on a linux box unless you don't need to see the images. The five functions can be distributed to five different computers on a network or all on one single computer (with web server not viewing the images). However, since the latter minimal setup requires the use of the computer attached to the microscope for all functions, it is not advisable. Processing server of Leginion is a multi-platform software, meaning it can run on both Microsoft Windows and [[Select Linux distribution to use|Linux]], Linux, although we and others have found that Windows have trouble managing its memory for such a demanding task. MySQL used in the database server is also supported by multiple platforms. This is not true for the Web server because the custom php-MRC module used in the web viewer only compiles on linux machines. Therefore, one of the computer not part of the microscope must be a linux. The following examples show several arrangements that take advantage of distributed system. Other combinations are possible, but will basically be variations on one of the following themes. h2. Configuration A *1 Windows computer (attached to the Microscope) & 1 Linux computer (for all other functions, separate from the Microscope) (Good for single user and small-scale acquisition)* * Install the latest processing server side of Leginon release (and supporting packages) on the Windows computer controlling the microscope and on the Linux computer which is to run Leginon image acquisition and processing. * Install the additional modules needed for CCD camera and film interaction on the Windows computer controlling the microscope. * Install MySQL, PHP, the Apache Web Server, and dbem tools only on the Linux computer that will perform these functions, (i.e. NOT the computer controlling the microscope). See [[Minimum_Requirements_and_current_NRAMM_setup]] h2. Configuration B *1 Windows computer (attached to the Microscope) & 4 Linux computers (one for each function) (Good for multiple microsopes, users and large-scale acquisition)* This is the set-up at NRAMM. It has the processing server side of Leginon installed on the Windows computer attached to the microscope and on the Linux computer that is used for running Leginon. A second Linux machine is dedicated to the database while the web-based viewer is hosted by another server. * Install the python-side Leginon (and supporting packages) on the Windows computer controlling the microscope and on the Linux computer that is to run Leginon. You can make the latter installation accessable to any numbers of linux computers on your network. * Install MySQL on a Linux computer served as the database server * Install PHP, the Apache Web Server, and PHP-side of Leginon system on the third Linux computer that will serve as the web server host. * The computer hosting the data storage should be accessable by all linux boxes. The data storage may be on one of these computers that is accessable by the web and the processing computers.
