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 administrator password.

      You set this password 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
