## Example: Enabling the MySQL Software to Run in the Cluster

1. Start the MySQL database manually on the node where the resource group is online.

       phys-schost-1# cd /usr/local/mysql
       phys-schost-1# ./bin/mysqld --defaults-file=/global/mnt3/mysql-data/my.cnf \
       --basedir=/usr/local/mysql --datadir=/global/mnt3/mysql-data \
       --pid-file=/global/mnt3/mysql-data/mysqld.pid \
       --user=mysql >> /global/mnt3/mysql-data/logs/ha-host-1.log 2>&1 &

2. Set the password for `localhost` in MySQL to root.

       phys-schost-1# /usr/local/mysql/bin/mysqladmin -S /tmp/ha-host-1.sock -uroot \
       password 'root'

3. Add an administrative user in the MySQL database for the logical host.

       phys-schost-1# /usr/local/mysql/bin/mysql -S /tmp/ha-host-1.sock -uroot -proot
       mysql> use mysql;
       mysql> GRANT ALL ON *.* TO 'root'@'phys-schost-1' IDENTIFIED BY 'root';
       mysql> GRANT ALL ON *.* TO 'root'@'phys-schost-2' IDENTIFIED BY 'root';
       mysql> UPDATE user SET Grant_priv='Y' WHERE User='root' AND Host='phys-schost-1';
       mysql> UPDATE user SET Grant_priv='Y' WHERE User='root' AND Host='phys-schost-2';
       mysql> exit

4. Prepare the Oracle Solaris Cluster specific test database.

       phys-schost-1# ksh /opt/SUNWscmys/util/mysql_register \
       -f /global/mnt3/mysql_config

   1. Enter `root` when you are asked for the MySQL admin password.

      You set it to `root` in Step 3.

   2. Enter a password when you are prompted for the fault monitor user password.
5. Stop the MySQL database.

       phys-schost-1# kill -TERM `cat /global/mnt3/mysql-data/mysqld.pid`

6. Make the `/global/mnt3/ha_mysql_config` file available on all nodes to run the MySQL database.
7. Encrypt the fault monitor user password on all nodes to run the MySQL database.

       phys-schost-1# ksh /opt/SUNWscmys/util/ha_mysql_register \
       -f /global/mnt3/ha_mysql_config -e
       phys-schost-2# ksh /opt/SUNWscmys/util/ha_mysql_register \
       -f /global/mnt3/ha_mysql_config -e

   Enter the same password you provided in Step 4 when you are prompted for the fault monitoring user password.

8. Run the `ha_mysql_register` script to register the resource.

       phys-schost-1# ksh /opt/SUNWscmys/util/ha_mysql_register \
       -f /global/mnt3/ha_mysql_config

9. Enable the resource.

       phys-schost-1# clresource enable RS-MYS
