Example: How to Enable the MySQL Software to Run in the Cluster

1. Start the MySQL database manually on both nodes.

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

   ---

   Note - Make sure to change phys-schost-1 to phys-schost-2 on the second node.

   ---

2. Set the password for localhost in MySQL to root on both nodes.

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

   ---

   Note - Make sure to change phys-schost-1 to phys-schost-2 on the second node.

   ---

3. Add an administrative user in the MySQL database for the physical host on both nodes.

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

   ---

   Note - Make sure to change phys-schost-1 to phys-schost-2 on the second node.

   ---

4. Prepare the Oracle Solaris Cluster specific test database on both nodes.

   phys-schost-1# ksh /opt/SUNWscmys/util/mysql_register -f /local/mysql_config

5. Stop the MySQL database.

   phys-schost-1# kill -TERM 'cat /local/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 on one node.

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

9. Enable the resource.

   phys-schost-1# clresource enable RS-MYSQL
