安装mysql出错

[root@wikilike7:10:50:03/usr/local/mysql]#mkdir -p /root/mysql/ ; chown -R mysql:mysql /root/mysql
[root@wikilike7:10:54:53/usr/local/mysql]#./scripts/mysql_install_db --user=mysql --datadir=/root/mysql
WARNING: The host 'wikilike7.centos' could not be looked up with 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 !
Installing MySQL system tables...
ERROR: 1  Can't create/write to file '/root/mysql/mysql/db.MYI' (Errcode: 13)
130725 10:55:39 [ERROR] Aborting

130725 10:55:39 [Note] ./bin/mysqld: Shutdown complete


Installation of system tables failed!  Examine the logs in
/root/mysql for more information.

You can try to start the mysqld daemon with:

    shell> ./bin/mysqld --skip-grant &

and use the command line tool ./bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> ./bin/mysql -u root mysql
    mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log
gives you a log in /root/mysql that may be helpful.

The latest information about MySQL is available on the web at
http://www.mysql.com/.  Please consult the MySQL manual section
'Problems running mysql_install_db', and the manual section that
describes problems on your OS.  Another information source are the
MySQL email archives available at http://lists.mysql.com/.

Please check all of the above before mailing us!  And remember, if
you do mail us, you MUST use the ./bin/mysqlbug script!
