这开始是一个根密码重置练习-但一直运行到各种错误：目前卡在3306端口的冲突。如果您想跳过前面的步骤，请参阅问题的最后几段（我只是在取得进展的同时不断更新问题和标题）。谢谢您。
我有一个安装了mysql的mac-但我记不起密码，因此我一直试图用以下方法重置密码：
https://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html (section:B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems) .
运行此命令时： mysqld --init-file=/home/me/mysql-init & 我有个错误：

`[1] 70374

因此我尝试这个命令： sudo /usr/local/mysql/support-files/mysql.server start --init-file=/usr/local/mysql/data/mysql-init 但现在我得到了一个错误： ERROR! The server quit without updating PID file (/usr/local/mysql/data/Deepaks-MacBook-Air.local.pid). 以下是日志文件的内容：

有什么问题，怎么解决？
ps：我已经提到了这两个所以，并尝试几乎所有的解决方案在所有的答案-重置权限，以删除所有的文件 /usr/local/var/mysql . 它仍然是同一个问题，我怀疑这与mysqld没有正常运行有关-是否有一种特殊的方式作为root运行它。我正在尝试在终端的根模式下运行 sudo -i . 有人能帮我调试一下吗？谢谢
mysql版本：

> mysql --version
mysql  Ver 14.14 Distrib 5.7.21, for osx10.12 (x86_64) using  EditLine wrapper

更新：我阅读了安全文档-显然你不应该以root模式运行它。所以我用 exit .
现在，我得到以下情况：

我怀疑这是由于删除了我的/usr/local/var/mysql目录，正如在另一个答案中建议的那样。我已经用这个删除了 rm -rf . 我做了一个新的目录 mkdir mysql 在 var 然后跑了 mysqld --init-file=/usr/local/mysql/data/mysql-init & ，它最初会给我一个pid，但是日志会询问我3306端口是否已被占用：

实际上我的电脑里有两个文件夹 /usr/local/ - mysql 以及 mysql-5.7.21-macos10.13-x86_64 . 整个过程到目前为止，我一直在运行的'mysql folder and haven't really touched mysql-5.7.21-macos10.13-x86\u 64。它们内部似乎有相同的目录结构。 当我这样做的时候ps aux | grep mysql` ，我得到三个过程：

Deepaks-MacBook-Air:local deepak$ ps aux | grep mysql
deepak           72071 100.0  0.0  2443044   1992 s002  S+    4:44PM   0:00.01 grep mysql

然而，当我继续杀死第二个或第三个，他们只是再次出现时，我做ps辅助。
另外，我通常使用portforwarding连接到远程mysql主机。所以，每隔一段时间我都会用本地脚本 "ssh -fNT -L 3307:localhost:3306 -i ~/key/deepak_ubuntu_16feb.pem ubuntu@ec2-AWS-HOS-TNA-ME.compute-1.amazonaws.com" 这会是一场冲突吗？
更新：好的，我忽略了另一个目录，只是简单地更改了端口，这看起来避免了冲突，但是现在有一个不同的问题：mysql.sock.lock不能被访问？

好吧，所以我去了 /tmp/ 并尝试检查文件的权限-结果如下：

Deepaks-MacBook-Air:tmp deepak$ stat mysql.sock.lock 
16777220 3413029 -rw------- 1 _mysql wheel 0 6 "May  6 16:25:35 2018" "May  6 16:25:35 2018" "May  6 16:25:35 2018" "May  6 16:25:35 2018" 4096 8 0 mysql.sock.lock

我试着从这篇文章中找出解决办法 https://stackoverflow.com/questions/34954455/mysql-daemon-lock-issue ，更改所有者的答案无效。我有点犹豫要不要解除锁定。
好的，这个帖子： https://support.rackspace.com/how-to/checking-linux-file-permissions-with-ls/ 相当简洁地解释了如何读取这些权限-显然在我的例子中，mysql user和wheel分别是所有者和组。这没道理，因为我从没见过 wheel 在a面以外的任何地方 .whl 在今天之前我还没有遇到过mysql。我已经尝试过使用 su - _mysql 我猜不出密码-不确定mysql是否默认设置了这个，在这种情况下我现在很困惑。
更新：好的，我解决了我的问题：

Deepaks-MacBook-Air:tmp deepak$ sudo chown deepak mysql.sock
Deepaks-MacBook-Air:tmp deepak$ sudo chown deepak mysql.sock.lock

但是，这会导致另一个错误： Can't open and lock privilege tables: Table 'mysql.user' doesn't exist .

好吧，通过使用将所有者从mysql更改为我的普通帐户，解决了这个问题 chown 但现在的问题是：

我是这样解决的：共享文件夹没有mysql目录，而是在英文目录下有errmsg.sys，我只是将这个文件复制到我在共享文件夹中创建的一个新目录中： mkdir mysql .
这起到了作用，但随后显示：

使用chown，我将mysql目录的所有者更改为我的常规用户帐户（奇怪的是，mysql-5.7.21-macos10.13-x86\u64目录不会将其所有者从group从root和wheel更改为anything，即使我使用了它）。
所以现在 mysqld --initialize-insecure --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --init-file=/usr/local/mysql/mysql-init --port=3308 & 命令来自 /usr/local/mysql/ 显示以下输出：

Deepaks-MacBook-Air:local deepak$ mysqld --initialize-insecure --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --init-file=/usr/local/mysql/mysql-init --port=3308 &

这看起来不错，但什么也没发生。是这个吗？我可以开始用我的sequelpro连接到'localhost:3308“现在？或者我需要解决一些其他问题，比如设置临时密码？在此之前，我是否需要进入另一个终端窗口尝试 mysql -u root 让它继续运行还是怎么样？
还有，当我不 ps aux | grep mysql 它像以前一样显示了三个过程，但没有显示 72460 我的QLD刚刚给我看的那个。这是我需要关心的吗？
这是我第一次这样做，我害怕现在做任何事，不破坏过去几个小时的努力来解决这个问题。
如何解决此问题？谢谢！

首先，以root身份运行的问题是mysqld不想拥有root权限。不过，以root用户身份运行它并没有错，因为默认情况下，数据目录应该不可写给您自己的用户。只需告诉它放弃特权并以“mysql”用户的身份运行，这是mysqld在macos上运行的默认用户，也可能是拥有数据目录的用户（注意，由于历史原因，“\u mysqld”和“mysql”在macos上指代同一个用户）。你可以通过添加 -u mysql 到mysqld的命令行。
这两个目录实际上应该只有一个目录（长名称包含版本号）和一个符号链接（/usr/local/mysql指向该目录）。mysql安装程序就是这样设置的，符号链接总是指向安装的mysql的最新版本。
您看到的另一个正在运行的mysqld是从launchd启动的mysqld。这也是mysql安装程序设置的。您可以使用mysql首选项窗格（默认情况下应该安装）将其关闭。否则，macos将继续重新启动它，因为它将停机解释为随机故障。首选项窗格应该位于系统首选项中最底行的末尾。
端口转发不应该是个问题。它只会在ssh连接启动时处于活动状态，甚至不会转发同一个本地端口。
