是的，另一个MySql: ERROR 1045(28000):用户“root”@“localhost”访问被拒绝(使用密码:Yes)

So I'm not sure what caused this to scramble my MySql password (upgrade to Mountain Lion, reinstalling ruby/rails (other issues), or simply just bad luck) but here we are:

因此，我不确定是什么原因导致我的MySql密码(升级到Mountain Lion，重新安装ruby/rails(其他问题)，或者只是运气不佳)出现混乱。

Logging in to mysql is fine, but I can't log into the root

登录到mysql很好，但是我不能登录到根目录。

当我试图登录到root:

Ayman$ mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Looked at the users:

看了看用户:

I've tried reinstalling MySql (not sure how to uninstall it), stopping the server instance and restarting it, and every other suggestion on the myriad of similar questions to the right. I've been on this for 3 days now and it's killing me.

我尝试过重新安装MySql(不知道如何卸载它)、停止服务器实例并重新启动它，以及对右侧大量类似问题的所有其他建议。我已经用了3天了，简直要了我的命。

Any clue?

有线索吗?

2 个解决方案

#1

You can start MySQL (the server, not the command line monitor) with --skip-grant-tables, which shuts off the permissions systems temporarily. That'll let you get in, update your accounts/passwords without those screwed up permissions getting in the way. Once things are fixed, you do a flush privileges; to re-enable the permissions system.

您可以使用—skip-grant-tables启动MySQL(服务器，而不是命令行监视器)，它临时关闭权限系统。这样你就可以进入，更新你的帐户/密码，而不需要那些搅乱你的权限。一旦事情得到了解决，你就拥有了齐平的特权;重新启用权限系统。

Ok I figured it out using the tutorial on this website:

我是通过这个网站上的教程算出来的

I had no clue how to run skip grant tables as evidenced below:

我不知道如何运作跳跳补助金表格，如下所示:

Last login: Wed Aug 22 23:10:42 on console
Ayman$ --skip-grant-tables
-bash: --skip-grant-tables: command not found
Ayman$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock'    (2)
Ayman$ --skip-grant-tables
-bash: --skip-grant-tables: command not found

Here is where I googled Skip Grant Tables and found the tutorial listed above:

在这里，我搜索了Skip Grant表，找到了上面列出的教程:

Don't think any of the initial part of the tutorial worked:

不要认为本教程的最初部分有用:

Ayman$ # vi /etc/rc.d/init.d/mysql
Ayman$ $bindir/mysqld_safe --datadir=$datadir --pid-file=$server_pid_file $other_args     >/dev/null 2>&1 &
[1] 302
Ayman$ $bindir/mysqld_safe --skip-grant-tables --datadir=$datadir --pid-  file=$server_pid_file $other_args >/dev/null 2>&1 &
[2] 303
[1]   Exit 127                $bindir/mysqld_safe --datadir=$datadir --pid-   file=$server_pid_file $other_args > /dev/null 2>&1
Ayman$ mysql start
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock'   (2)
[2]+  Exit 127                $bindir/mysqld_safe --skip-grant-tables --datadir=$datadir -  -pid-file=$server_pid_file $other_args > /dev/null 2>&1
Ayman$ # service mysql start
Ayman$ mysql -u root mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Ayman$ mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

错误2002 (HY000):无法通过socket '/tmp/ MySQL连接到本地MySQL服务器。袜子”(2)

HERE IS THE MAGIC!:

这是神奇的!
