Installation on MySQL
Replacing the simple SQLite database with MySQL allows greater scalability
1) The databases directory contains what web2py knows about your database
2) You need to set Migrate=True in 00_db.py before you update the code and switch back to Migrate = False later on.
3) In case of database mismatches - check the databases directory for the appropriate table ( cat the file ) and change accordingly.
Install Python support for MySQL:
apt-get install python-mysqldb
wget http://downloads.sourceforge.net/project/mysql-python/mysql-python-test/1.2.3c1/MySQL-python-1.2.3c1.tar.gz tar zxvf MySQL-python-1.2.3c1.tar.gz cd MySQL-python-1.2.3c1 python setup.py install
Create the database 1st:
mysqladmin --user=root -p create sahana mysql -p GRANT USAGE ON sahana.* TO 'sahana'@'localhost' IDENTIFIED BY 'mypassword';
Suggest to use connection pools to reuse connections in
How many pools?
whatever you choose it always starts with one and grows with the number of concurrent requests up to the value of pools (the max number of concurrent pools). So pools should be the max number of concurrent requests you expect. That is the max value of: <number of requests/second> / <average time per request in seconcds>
