WARNING: The host 'centos1' could not belooked up with /usr/local/mysql5.638//bin/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 addresses instead of hostnames
when specifying MySQL privileges !

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 THEMySQL root USER !
To do so, start the server, then issue thefollowing commands:
/usr/local/mysql5.638//bin/mysqladmin -u root password 'new-password'
/usr/local/mysql5.638//bin/mysqladmin -u root -h centos1 password'new-password'
Alternatively you can run:
/usr/local/mysql5.638//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/mysql5.638//bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cdmysql-test ; perl mysql-test-run.pl
Please report any problems athttp://bugs.mysql.com/

New default config file was created as/usr/local/mysql5.638//my.cnf and
will be used by default by the server whenyou start it.
You may edit this file to change serversettings
WARNING: Default config file /etc/my.cnfexists on the system
This file will be read by default by theMySQL server
If you do not want to use this, eitherremove it, or use the
--defaults-file argument to mysqld_safewhen starting the server
