新装的mysql，访问mysql数据库是遇到问题：ERROR 1044 (42000): Access denied for user ‘‘@‘localhost‘to database ‘mysql‘，
[[email protected] mysql-5.1.61]# mysql -u root -p
Enter password:

mysql> use mysql
ERROR 1044 (42000): Access denied for user ‘‘@‘localhost‘ to database ‘mysql‘
mysql>
最后发现解决方案是：
打开my.ini,在
[mysqld]
skip-external-locking
skip-name-resolve
#skip-grant-tables
其中skip-grant-tables跳过权限验证是被注释掉的，去掉注释，重新启动mysql：
[[email protected] libexec]# /usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/data0/mysqldata --user=mysql --log-error=/data0/mysqldata/mysql-error.log --open-files-limit=20000 --pid-file=/data0/mysqldata/dzwww.com-B15-5-3-36.pid
--socket=/tmp/mysql.sock --port=3306
[[email protected] mysql-5.1.61]# mysql -u root -p
Enter password:

然后重新登录 ok,成功！
