MySQL上的用户'user'@'localhost'访问被拒绝

Question

我正在尝试将我连接到数据库MySQL服务器，但控制台显示 ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) 我不知道为什么。请帮我。在我的文件my.cnf中，我有类似的内容，

[mysqld]
datadir=/var/lib/mysql
socket=/tmp/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# To allow mysqld to connect to a MySQL Cluster management daemon, uncomment
# these lines and adjust the connectstring as needed.
#ndbcluster
#ndb-connectstring="nodeid=4;host=localhost:3306"

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[ndbd]
# If you are running a MySQL Cluster storage daemon (ndbd) on this machine,
# adjust its connection to the management daemon here.
# Note: ndbd init script requires this to include nodeid!
connect-string="nodeid=2;host=localhost:3306"

[ndb_mgm]
# connection string for MySQL Cluster management tool
connect-string="host=localhost:3306"

[client]
socket=/tmp/mysql.sock

感谢。

如果你真的不记得通行证，你可以将skip_grant_tables添加到[mysqld]的{​​{1}}部分，重启服务器，它会让你进入而没有密码，然后您可以通过更新my.cnf表来更改密码，然后重新启动mysql，删除mysql.user选项。

-p标志表示密码要求。输入您键入的请求密码后应该有第二个提示。例如：

$ mysql -u root -p
$ Enter password: 

然后输入密码。
