Upgrade to Leginon System version 30 from version 22 (Linux)¶

Leginon/Appion 3.0 release web image viewer will not be compatible with CentOS 5 due to prerequisites of REDUX, the new image server that is compatible with php 5.3 used in modern os. The Leginon processing server code is still compatible with python 2.4 which came with CentOS 5 but the development from now on will assume python version 2.6 along with other default yum installed packages of CentOS 6. Database server does not require upgrade.

Upgrade web server¶

Follow Complete Web Server Installation including os upgrade to CentOS 6 if you are upgrading from the non-redux version of myami 2.2¶

Other OS with php 5.3 and above should also work but we can't provide instruction for all individual cases.

Upgrade processing server¶

OS upgrade to CentOS 6 upgrade is OPTIONAL for standalone processing server¶

Download myami 3.0 source code¶

svn co http://emg.nysbc.org/svn/myami/branches/myami-3.0/

Install Appion/Leginon Packages¶

Install all the myami python packages except appion using the following script:¶

cd /your_download_area
cd myami
sudo ./pysetup.sh install

That will install each package, and report any failures. To determine the cause of failure, see the generated log file "pysetup.log". If necessary, you can enter a specific package directory and run the python setup command manually. For example, if sinedon failed to install, you can try again like this:

cd sinedon
sudo python setup.py install

Move leginon.cfg/instruments.cfg/sinedon.cfg if it was saved with the old installation.¶

Run this script to find out where it was:

 
cd /your_download_area/myami/leginion/
./configcheck.py

If the script can not find leginon.cfg, and you found a copy of leginon.cfg in $PYTHONSITEPKG/leginon/config from the last installation, move that leginon.cfg to $PYTHONSITEPKG/leginon.

Run Database Update Script¶

Running the following script will indicate if you need to run any database update scripts.

cd /your_download_area/myami/dbschema
python schema_update.py

This will print out a list of commands to paste into a shell which will run database update scripts.
You can re-run schema_update.py at any time to update the list of which scripts still need to be run.
