WARNING: The host 'mysql01' could not belooked up with resolveip.
This probably means that your libclibraries are not 100 % compatible
with this binary MySQL version. The MySQLdaemon, mysqld, should work
normally with the exception that host nameresolving will not work.
This means that you should use IP addressesinstead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have tocopy
support-files/mysql.server to the rightplace for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER !
To do so, start the server, then issue thefollowing commands:
/usr/local/mysql//bin/mysqladmin -u rootpassword 'new-password'
/usr/local/mysql//bin/mysqladmin -u root -hmysql01 password 'new-password'
Alternatively you can run:
/usr/local/mysql//bin/mysql_secure_installation
which will also give you the option ofremoving the test
databases and anonymous user created bydefault. This is
strongly recommended for productionservers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr/local/mysql/ ;/usr/local/mysql//bin/mysqld_safe &
You can test the MySQL daemon withmysql-test-run.pl
cd /usr/local/mysql//mysql-test ; perlmysql-test-run.pl
Please report any problems with the/usr/local/mysql//scripts/mysqlbug script!
