mysql - MySQL 上的用户 'user' @'localhost' 的访问被拒绝

Question

我正在尝试将我连接到数据库 MySQL 服务器，但控制台显示错误 1045 (28000): 用户 'root'@'localhost' 的访问被拒绝(使用密码:YES)我不知道为什么。请帮我。在我的文件 my.cnf 中，我有这样的内容，

[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

谢谢。

如果您真的不记得密码了，您可以将 skip_grant_tables 添加到 my.cnf 的 [mysqld] 部分，重新启动服务器，它会让你无需密码即可进入，然后你可以通过更新mysql.user表来更改密码，然后重新启动mysql并删除skip_grant_tables选项。
