| Generally, you will want to create a user account for running emen2, e.g. 'emen2.' This has the benefit of working well with the default config file. Running as any other user also works fine, you will just have to change one or two paths in config.yml. | <<TableOfContents>> |

| If you have an existing database environment, I strongly recommend taking an additional tar backup of that directory before proceeding, in addition to normal backup procedures (log archive, db hot backup) in case you need to revert without the difficulty of performing a full recovery from archives. | = Initialize EMEN2 Environment = |

| Create a directory for the Database Environment (referred to as DB_HOME going forward. Reasonable default is /home/emen2/db/ ) Recommended: Set the DB_HOME environment variable to this path for convenience. You will also need to add the EMEN2 source directory to your PYTHONPATH environment variable Place this in your .bash_profile or similar. {{{ export DB_HOME=/home/emen2/db export PYTHONPATH=$PYTHONPATH:/home/emen2/emen2/ }}} {{{ mkdir $DB_HOME cp config/config.sample.yml $DB_HOME/config.yml }}} === 3. Create Configuration === Copy emen2/config.sample.yml to DB_HOME/config.yml Edit the various settings in config.yml. See [[EMEN2/config.yml]]. Primarily, you will want to check the path and network settings. A simple configuration will have most EMEN2 directories (db, applog, archive, db_hotbackup, emen2files, etc.) placed under the path specified by the "&root" element, which is /home/emen2/ by default. {{{ root: &root /home/emen2/ }}} === 4. Initial DB_HOME setup === After config.yml is to your liking, run {{{ python ./setup.py }}} The rest of the DB_HOME environment will be created, skeleton parameter/protocol definitions will be installed, and a root user created. You will be prompted on the shell for a root password. === 5. Test web server === {{{ python ./TwistSupport.py }}} You should be able to connect to this web server instance once it is "listening..." The default port is 8080. You may login with the root password you specified previously. === 6. Optional: Import === You may want to import the parameter and protocol definitions from the EMEN2 installation at the NCMI. In the future, these will be published in an open format, and made available by default. {{{ python ./clients/clone.py -- --defs }}} Note: the first "--" is intentional and required at the moment. Command arguments for the local database go before "--", arguments to the cloning script go after ("--defs") You will be prompted for two sets of credentials. First, an NCMI DB account, and second, the root password for the local database. If you do not have an NCMI DB account, you may specify "anonymous" as the username, and your email address as the password. === 7. Run as daemon === After you are satisfied with your setup, you can run EMEN2 in the background {{{ python ./emen2control.py --start }}} |
