Set a password for root user [#1]

To set a password for your mysql root user, edit the build.properties file and edit these properties as neccesary:

    #database.jar=${postgresql.jar}
    #database.type=postgresql
    #database.name=appfuse
    #database.host=localhost
    #database URL for creating other databases (doesn't work with pgsql)
    #database.admin.url=jdbc:${database.type}://${database.host}/template1
    #database.admin.username=postgres
    #database.admin.password=postgres

    #hibernate.dialect=net.sf.hibernate.dialect.PostgreSQLDialect
    #database.driver_class=org.postgresql.Driver
    #database.url=jdbc:${database.type}://${database.host}/${database.name}

You should uncomment the password line to look like this:

    database.admin.password=myrootpassword

Where myrootpassword is your root user password.

Your root account is not setup correctly [#2]

When you login to mysql there are a number of databases available to you. One of these databases is called mysql which is the 'system' database. Within the mysql database, there is a table called 'users' which holds all the mysql user information, along with their grants (their privileges).

The users table also contains a 'host' column. The root user needs a record entry in the users table for each 'host' it is going to login from. ie. 'mypc', 'localhost' and the wildcard '%'.

Both the grants, and the host columns need to be setup correctly for ant setup to run smoothly.

These instructions tell you how to setup the root user with no password. Once you have ant setup successfully, you can set a password on the root account.

(Please note: You do not have to setup the root account in this way, it is possible to perform the following steps and give the root user a password, see [1]. But the following steps should work for you.)

In this example, we will pretend your hostname is 'mypc'. Also, where ${MYSQL_HOME} is shown, please replace that with the path to your mysql installation. At the end of these steps, you should be able to login to your mysql database and see this:

    $ mysql -u root
    mysql> use mysql;
    Database changed

    mysql> select user, host, password from user where user = "root";

    +------+-----------+----------+
    | user | host      | password |
    +------+-----------+----------+
    | root | localhost |          |
    | root | mypc      |          |
    | root | %         |          |
    +------+-----------+----------+
    3 rows in set (0.00 sec)

and if you execute select * from user where user = "root"; we want to see Y's on all the grant columns within the user table, which denotes that the root user has all the neccesary grant options to be able to setup the appfuse database and give the test user privileges on it.

First we want to stop the mysql db, so execute this command:

    mysqladmin -u root -p shutdown

If mysql is still running (check the process on UNIX or use TaskManager on Windows), then kill the process:

    (UNIX) killall mysqld
    (Windows) Use task manager or stop the mysqld service

Now we want to restart mysql but bypass the authentication tables so we can go in and change the user database table, so now execute this command (UNIX command given but for Windows, leaving out the ampersand):

    ${MYSQL_HOME}/bin/mysqld_safe --skip-grant-tables &

Now log back into mysql and remove any old root entries in your user table:

    mysql -u root
    use mysql;
    delete from user where user='root';
    commit;
    FLUSH PRIVILEGES;

Now we want to setup the root user using the GRANT command, so execute the following commands (Note you should change mypc to your hostname or hostname.domainname:

    mysql -u root
    use mysql;
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
    FLUSH PRIVILEGES;
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;
    FLUSH PRIVILEGES;
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'mypc' WITH GRANT OPTION;
    FLUSH PRIVILEGES;
    quit;

Note: If you want to set a root password at this stage (and then specify it build.properties as defined in [1]), then you need to modify the GRANT commands to:

    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' 
        IDENTIFIED BY 'myrootpassword' WITH GRANT OPTION;

Replacing 'myrootpassword' to be what you want the root user password to be.

We now have the root user setup properly, lets restart mysql without bypassing the authentication stuff.. Stop mysql using the instructions above once more. Now, if you run ant setup you should be ok, if you are still getting errors, it is likely you need to perform the steps in [3]. If you are up and running, you should not set the root password as described in [4].

The grants for the test user account are not being setup properly [#3]

If you are seeing an error message that says:

    Invalid authorization specification message from server: 
        "Access denied for user: 'test@mypc' (Using password: YES)"

Then you need to change metadata/sql/mysql-create.sql to specify your hostname (along with your domain name if you have one, else just your hostname). Here is an example of what a modified file might look like if your hostname is 'mypc':

    create database if not exists appfuse;
    grant all privileges on appfuse.* to test@localhost identified by "test";
    grant all privileges on appfuse.* to test@mypc identified by "test";

Set the root password [#4]

To set the root password, type the following commands :

    $ mysql -u root
    mysql> use mysql;
    Database changed

Now we want to set the password field for any root user records in the users table. Type this command:

    UPDATE user SET Password=PASSWORD('myrootpassword')
        WHERE User='root';

    FLUSH PRIVILEGES;

Where myrootpassword is your root user password.
