h1. How to Update from v16 (Linux) The changes from v1.6 requires update of all in-house components of Leginon, dbemtools (called myamiweb in the new version) and database but *not the php mrctools*. *This processing package upgrade instruction includes that for installing Appion's processing scripts and executables. They have more supporting package requirement. Therefore, if you do not plan to use Appion on this computer, you may skip it.* Don't forget that you need to also update the packages on the microscope-controlling computer since the pyScope update need to be synchronized. See [[Installation Troubleshooting]] and "Leginon Bulletin Board":http://emg.nysbc.org/boards/6 Board":http://emg.nysbc.org/bb/viewforum.php?f=2 searching for "install" if you run into problems. h2. Packages required from NRAMM All Leginon (and Appion) packages distributed from NRAMM are now under one svn control called myami. A few updates are needed for preparation of python 3.0 compatibility where the method for importing module is changed. They will still run under python 2.4 and up. Here are the packages you need to install with python installer |_.SVN subPackage Name|_.Reason for update:| |numextension|package import method change| |libcv|package import method change| |leginon|new features| |pyami|new features| |sinedon|required for updating database| |pyscope|new method for creating pythoncom modules| |imageviewer|debug| h2. Download Leginon 2.0 source code {{include(appion:Download_Appion_Files_Shared)}} h2. Perform system check if you can't remember where you have installed your Leginon before. <pre>cd /your_download_area/myami/leginon python syscheck.py</pre> You should have all the supporting packages installed for v1.6. If you see any lines like "*** Failed...", then you have something missing. Otherwise, everything should result in "OK". h2. Move your existing python processing packages to a backup directory: At the beginning of the syscheck.py output, the location of the exisiting Leginon folder is shown. Although new installation overwrite the old in most cases, problem has been observed in the past. Therefore, it is best to remove the old files from the path before new installation. Better yet, copy into a backup folder because we need some configuration files from them. For example, your Leginon folder is at /usr/lib/python/site-packages/Leginon <pre>cd /usr/lib/python/site-packages mkdir Leginon1_6_backup mv Leginon Leginon1_6_backup</pre> Be aware that in some cases the installed package name is different (capitalized) from your svn package name and that numextension amd libCV are not in its own subdirectory in the python library but just the compiled .so files {{include(appion:Install Appion Packages Shared)}} h2. Copy your Leginon1.6 sinedon.cfg to the new installation * Find your sinedon.cfg. Depending on your previous setting, look in the directories listed here in order: *your home directory as described in syscheck.py *The sinedon directory where it is called from. If unsure, start python command line and type these to find out: <pre>python> import sinedon python> sinedon</pre> * If sinedon.cfg reside in the installed sinedon subpackage, you should copy it from your Leginon1,6 backup to the new installation. <pre>cd /your_default_python_installation_path cp Leginon_1_6_backup/sinedon/sinedon.cfg sinedon </pre> h2. Copy your Leginon1.6 leginon.cfg to the new installation similarly * Find your leginon.cfg. Depending on your previous setting, look in the directories listed here in order: *your home directory as described in syscheck.py *The leginon directory where it is called from. If unsure, start python command line and type these to find out: <pre>python> import leginon python> leginon</pre> * If leginon.cfg reside in the installed leginon subpackage, you should copy it from your Leginon1,6 backup to the new installation. <pre>cd /your_default_python_installation_path cp Leginon_1_6_backup/Leginon/leginon.cfg leginon </pre> h2. Back up all your databases h3. Check your database for bad tables We've found this on two databases outside NRAMM that there are empty tables created that causes a bad database backup. Please check and correct your database first before your backup. # start mysql command line on your leginondb <pre> mysql -u usr_object your_leginon_database </pre> # display all tables <pre> mysql> show tables; </pre> # if you find both BindngSpecData and bindingspecdata, you have a problem. The former has data in there and the later does not. If you have data in both tables, please contact us. We will need to create a customized solution. You can check like this: <pre> mysql> select * from BindingSpecData; mysql> select * from bindingspecdata; </pre> # remove the empty lowercased table <pre> mysql> drop table bindingspecdata; </pre> # repeat 3-4 on launchedapplicationdata and nodespecdata h3. Backup We will be doing a database update that is not backward compatible, Make sure you back up all your current databases before performing the update * mysqldump -u usr_object your_leginon_database > leginondb_1_6_backup_today's_date * mysqldump -u usr_object your_project_database > projectdb_1_2_backup_today's_date * .... do the same to any of your processing databases if you have installed and used Appion 1.0 beta h2. Install updated Web viewers and tools *You will not need to upgrade php mrc tools*. See [[Install the Web Interface]] section in Complete Installation Chapter to put the new web tools (Now under subpackage myamiweb) to document root for the web server. The Setup Wizard will take you through the steps to create config.php and to create and initialize values for the new tables. You will be asked about whether you want to enable myamiweb user login feature that restricts individual user's access to projects and administrator features. Read about it [[appion:User Management|here]] h2. Check and modify your [[Configure_sinedoncfg|sinedon.cfg]] to be compatible to the new version All module names are now all in lower cass. h2. Run database update scripts <pre>cd /your_download_area/myami/dbschema python schema-r12857.py python schema-r13713.py python schema-r14077.py </pre> The first one updates UserData and GroupData so that new data viewing and processing privileges can be enforced The second is a wide-scale change on database schema many on appion processing databases, and some on projectdata and leginondata. The third fills in some appion data that was obtained with slow query in previous versions. ______ [[How_to_Update_from_v16_(Microscope_Windows_Computer)|How to Update from v1.6 (Microscope Windows Computer) >]] ______
