Initializing MySQL database: WARNING: The host 'centos-512mb-sgp1-06'

could not be looked up with /usr/bin/resolveip. This probably means that

your libc libraries are not 100 % compatible with this binary MySQL

version. The MySQL daemon, mysqld, should work normally with the exception

that host name resolving will not work. This means that you should use IP

addresses instead of hostnames when specifying MySQL privileges !

Shutdown completed; log sequence number 1625987 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:

/usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u

root -h 127.0.0.1 password 'new-password' Alternatively you can run:

/usr/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 /usr ;

/usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-

run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems

at http://bugs.mysql.com/ The latest information about MySQL is available

on the web at http://www.mysql.com Support MySQL by buying

support/licenses at http://shop.mysql.com Note: new default config file

not created. Please make sure your config file is current WARNING: Default

config file /etc/my.cnf exists on the system This file will be read by

default by the MySQL server If you do not want to use this, either remove

it, or use the --defaults-file argument to mysqld_safe when starting the

server [ OK ]
