Sun Cluster Data Service for MySQL Guide for Solaris OS

Installing and Configuring MySQL on Local Storage in the Global Zone

The tasks you must perform to install and configure MySQL in the global zone are as follows:

ProcedureExample: Preparing the Cluster for MySQL

  1. Install and configure the cluster as instructed in Sun Cluster Software Installation Guide for Solaris OS.

    Install the following cluster software components on both nodes.

    • Sun Cluster core software

    • Sun Cluster data service for MySQL

  2. Beginning on the node that owns the file system, add the mysql user. 


    phys-schost-1# groupadd -g 1000 mysql
phys-schost-1# useradd -g 1000 -d /global/mnt3/mysql -m -s /bin/ksh mysql
phys-schost-2# groupadd -g 1000 mysql
phys-schost-2# useradd -g 1000 -d /global/mnt3/mysql -m -s /bin/ksh mysql

ProcedureExample: Configuring Cluster Resources for MySQL

  1. Register the necessary data types on one of the nodes.


    phys-schost-1# clresourcetype register SUNW.gds SUNW.HAStoragePlus

  2. Create the MySQL resource group. 


    phys-schost-1# clresourcegroup create RG-MYS

  3. Create the logical host.


    phys-schost-1# clreslogicalhostname create -g RG-MYS ha-host-1

  4. Create the HAStoragePlus resource in the RG-MYS resource group.


    phys-schost-1# clresource create -g RG-MYS -t SUNW.HAStoragePlus -p AffinityOn=TRUE \
-p FilesystemMountPoints=/global/mnt3,/global/mnt4 RS-MYS-HAS

  5. Enable the resource group.


    phys-schost-1# clresourcegroup online -M RG-MYS

ProcedureExample: Installing and bootstrapping the MySQL Software on Local Storage

These steps illustrate how to install the MySQL software in the default directory /usr/local/mysql. As long as only one node is mentioned it needs to be the node where your resource group is online.

  1. Install the MySQL binaries on both nodes.


    phys-schost-1# cd /usr/local
phys-schost-1# tar xvf mysql-max-5.0.22-solaris10-architcture_64.tar.gz
phys-schost-1# ln -s mysql-max-5.0.22-solaris10-architcture_64 mysql

  2. Change the ownership of the MySQL binaries on both nodes.


    phys-schost-1# chown -R mysql:mysql /usr/local/mysql

  3. Create your data base directories.


    phys-schost-1# mkdir -p /global/mnt3/mysql-data/logs
phys-schost-1# mkdir /global/mnt3/mysql-data/innodb
phys-schost-1# mkdir /global/mnt3/mysql-data/BDB

  4. Bootstrap MySQL.


    phys-schost-1# cd /usr/local/mysql
phys-schost-1# ./scripts/* --datadir=/global/mnt3/mysql-data

  5. Create your my.cnf config-file in /global/mnt3/mysql-data


    phys-schost-1# cat > /global/mnt3/mysql-data/my.cnf << EOF
[mysqld]
server-id=1
#port=3306
# 10.18.5.1 is the address of the logical host
bind-address=10.18.5.1 # this is the address of the logical host
socket=/tmp/hahostix1.sock
log=/global/mnt3/mysql-data/logs/log1
log-bin=/global/mnt3/mysql-data/logs/bin-log
binlog-ignore-db=sc3_test_database
log-slow-queries=/global/mnt3/mysql-data/logs/log-slow-queries
#log-update=/global/mnt3/mysql-data/logs/log-update

# Innodb
#skip-innodb
innodb_data_home_dir = /global/mnt3/mysql-data/innodb
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /global/mnt3/mysql-data/innodb
innodb_log_arch_dir = /global/mnt3/mysql-data/innodb
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
set-variable = innodb_buffer_pool_size=50M
set-variable = innodb_additional_mem_pool_size=20M
# Set .._log_file_size to 25 % of buffer pool size
set-variable = innodb_log_file_size=12M
set-variable = innodb_log_buffer_size=4M
innodb_flush_log_at_trx_commit=1
set-variable = innodb_lock_wait_timeout=50

# BDB
# uncomment the skip-bdb if you used a binary download.
# binary downloads come very often without the bdb support.
#skip-bdb
bdb-home=/global/mnt3/mysql-data
bdb-no-recover
bdb-lock-detect=DEFAULT
bdb-logdir=/global/mnt3/mysql-data/BDB
bdb-tmpdir=/global/mnt3/mysql-data/BDB
#bdb_max_lock=10000


# Replikering Slave
#server-id=2
#master-host=administerix
#master-user=repl
#master-password=repl
#master-info-file=/global/mnt3/mysql-data/logs/master.info

# MySQL 4.x
#relay-log=/global/mnt3/mysql-data/logs/slave-bin.log
#relay-log-info-file=/global/mnt3/mysql-data/logs/slave-info

  6. Change the ownership of the MySQL data directory.


    phys-schost-1# chown -R mysql:mysql /global/mnt3/mysql-data

  7. Change the permission of the my.cnf file.


    phys-schost-1# chmod 644 /global/mnt3/mysql-data/my.cnf

ProcedureExample: Modifying the MySQL Configuration Files

  1. Copy the MySQL configuration file from the agent directory to its deployment location. 


    phys-schost-1# cp /opt/SUNWscmys/util/mysql_config /global/mnt3
phys-schost-1# cp /opt/SUNWscmys/util/ha_mysql_config /global/mnt3

  2. Add this cluster's information to the mysql_config configuration file.

    The following listing shows the relevant file entries and the values to assign to each entry. 


    .
.
.
MYSQL_BASE=/usr/local/mysql
MYSQL_USER=root
MYSQL_PASSWD=root
MYSQL_HOST=ha-host-1
FMUSER=fmuser
FMPASS=fmuser
MYSQL_SOCK=/tmp/ha-host-1.sock
MYSQL_NIC_HOSTNAME="phys-schost-1 phys-schost-2"
MYSQL_DATADIR=/global/mnt3/mysql-data

  3. Add this cluster's information to the ha_mysql_config configuration file.

    The following listing shows the relevant file entries and the values to assign to each entry. 


    .
.
.
RS=RS-PGS
RG=RG-MYS
PORT=5432
LH=hahostix1
HAS_RS=RS-MYS-HAS
.
.
.
BASEDIR=/usr/local/mysql
DATADIR=/global/mnt3/mysql-data
MYSQLUSER=mysql
MYSQLHOST=ha-host-1
FMUSER=fmuser
FMPASS=fmuser
LOGDIR=/global/mnt3/mys-data/logs
CHECK=YES

  4. Save and close the file.

ProcedureExample: 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 admin 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 Sun Cluster specific test database. 


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

  5. Stop the MySQL database. 


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

  6. 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

  7. Enable the resource.


    phys-schost-1# clresource enable RS-MYS
