  • 遇到错误ERROR 1044 (42000): Access denied for user ''@'localhost'to database 'mysql',的解决办法

    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',

    [root@dzwww mysql-5.1.61]# mysql -u root -p
    Enter password:
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 1
    Server version: 5.1.61 Source distribution

    Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

    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:

    [root@aaa 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

    [root@dzwww mysql-5.1.61]# mysql -u root -p
    Enter password:
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 1
    Server version: 5.1.61-log Source distribution

    Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

    mysql> use mysql
    Database changed
    mysql>grant all privileges on *.* to root@localhost identified by 'mysql'

    然后重新登录 ok,成功!
