* MANUAL SETUP INSTRUCTIONS
*
* 1) in /etc/gnunet.conf, set
- * <pre>
- * [datastore]
- * DATABASE = "mysql"
- * </pre>
+ * @verbatim
+ [datastore]
+ DATABASE = "mysql"
+ @endverbatim
* 2) Then access mysql as root,
- * <pre>
- *
- * $ mysql -u root -p
- *
- * </pre>
+ * @verbatim
+ $ mysql -u root -p
+ @endverbatim
* and do the following. [You should replace $USER with the username
* that will be running the gnunetd process].
- * <pre>
- *
+ * @verbatim
CREATE DATABASE gnunet;
GRANT select,insert,update,delete,create,alter,drop,create temporary tables
ON gnunet.* TO $USER@localhost;
SET PASSWORD FOR $USER@localhost=PASSWORD('$the_password_you_like');
FLUSH PRIVILEGES;
- *
- * </pre>
+ @endverbatim
* 3) In the $HOME directory of $USER, create a ".my.cnf" file
* with the following lines
- * <pre>
-
+ * @verbatim
[client]
user=$USER
password=$the_password_you_like
-
- * </pre>
+ @endverbatim
*
* Thats it. Note that .my.cnf file is a security risk unless its on
* a safe partition etc. The $HOME/.my.cnf can of course be a symbolic
* 4) Still, perhaps you should briefly try if the DB connection
* works. First, login as $USER. Then use,
*
- * <pre>
- * $ mysql -u $USER -p $the_password_you_like
- * mysql> use gnunet;
- * </pre>
+ * @verbatim
+ $ mysql -u $USER -p $the_password_you_like
+ mysql> use gnunet;
+ @endverbatim
*
* If you get the message "Database changed" it probably works.
*
* - The tables can be verified/fixed in two ways;
* 1) by running mysqlcheck -A, or
* 2) by executing (inside of mysql using the GNUnet database):
- * mysql> REPAIR TABLE gn080;
- * mysql> REPAIR TABLE gn072;
+ * @verbatim
+ mysql> REPAIR TABLE gn090;
+ mysql> REPAIR TABLE gn072;
+ @endverbatim
*
* PROBLEMS?
*
* to it, create tables, issue queries etc.
*
* TODO:
- * - implement GET
- * - remove 'size' field in gn080.
* - use FOREIGN KEY for 'uid/vkey'
* - consistent naming of uid/vkey
*/
automatically apply a LIMIT on the outermost clause, so we need to
repeat ourselves quite a bit. All hail the performance gods (and thanks
to #mysql on freenode) */
