2.Create the volume for mysql

bash-3.00# vxassist -g datadg make mysqlvol 1500m layout=nolog

 

bash-3.00# mkdir /mysql

bash-3.00# newfs /dev/vx/dsk/datadg/mysqlvol

/dev/vx/rdsk/datadg/mysqlvol: Unable to find Media type. Proceeding with system determined parameters.

newfs: construct a new file system /dev/vx/rdsk/datadg/mysqlvol: (y/n)? y

/dev/vx/rdsk/datadg/mysqlvol: 3072000 sectors in 1500 cylinders of 32 tracks, 64 sectors

1500.0MB in 47 cyl groups (32 c/g, 32.00MB/g, 7936 i/g)

super-block backups (for fsck -F ufs -o b=#) at:

32, 65632, 131232, 196832, 262432, 328032, 393632, 459232, 524832, 590432,

2425184, 2490784, 2556384, 2621984, 2687584, 2753184, 2818784, 2884384,

2949984, 3015584

 

 

3.Install mysql

On both nodes:

groupadd mysql

useradd -g mysql mysql

 

on only one node:

cp support-files/my-medium.cnf /mysql/mysql/my.cnf

mount /dev/vx/dsk/datadg/mysqlvol /mysql

cp -r mysql-5.1.73-solaris10-x86_64 /mysql/

bash-3.00# ln -s mysql-5.1.73-solaris10-x86_64 mysql

bash-3.00# scripts/mysql_install_db –user=mysql –basedir=/mysql/mysql

Installing MySQL system tables…

OK

Filling help tables…

OK

 

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

 

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

 

/mysql/mysql/bin/mysqladmin -u root password ‘new-password’

/mysql/mysql/bin/mysqladmin -u root -h solarisB password ‘new-password’

 

Alternatively you can run:

/mysql/mysql/bin/mysql_secure_installation

 

which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

 

See the manual for more instructions.

 

You can start the MySQL daemon with:

cd /mysql/mysql ; /mysql/mysql/bin/mysqld_safe &

 

You can test the MySQL daemon with mysql-test-run.pl

cd /mysql/mysql/mysql-test ; perl mysql-test-run.pl

 

Please report any problems with the /mysql/mysql/scripts/mysqlbug script!
