在macOS上安装mysql

我正在尝试在mac os 10.6上使用Homebrew by brew安装MySQL 5.1.52。

一切都很顺利，我也成功地使用mysql_install_db。然而，当我试图连接到服务器使用:

/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin -u root password 'mypass'

我得到:

/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin: connect to server at 'localhost' 
failed error: 'Access denied for user 'root'@'localhost' (using password: NO)'

我尝试访问mysqladmin或mysql使用-u root - root以及，但是有没有密码都不行。

这是全新机器上的全新安装，据我所知，新安装必须在没有根密码的情况下访问。我还试过:

/usr/local/Cellar/mysql/5.1.52/bin/mysql_secure_installation

但我也得到了

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

当前回答

如果mysql已经安装

完全停止mysql。

mysql。服务器停止<——可能需要根据您的版本进行编辑 Ps -ef | grep mysql <——列出名称中包含mysql的进程 kill [PID] <——按PID终止进程

删除文件。上面的说明很好。我将添加:

Sudo find /。mysql - name“* *” 根据你的判断，rm -rf这些文件。请注意，许多程序都有mysql的驱动程序，您不想删除它们。例如，不要删除PHP安装目录中的内容。删除它自己的mysql目录中的东西。

安装

希望你有自制的。如果没有，请下载。

我喜欢以root用户运行brew，但我认为您不必这样做。编辑2018:你不能再以root用户运行brew了

Sudo brew更新 Sudo brew install cmake <——mysql的依赖关系，有用 Sudo brew install openssl <——依赖于mysql，有用 Sudo brew info mysql <—撇过这个…它让你知道接下来会发生什么 Sudo brew install mysql -with-embedded用嵌入式服务器安装mysql。告诉你什么时候完成(我的安装花了10分钟)

后来

sudo chown -R mysql /usr/local/var/mysql/ <——mysql不为我工作，直到我运行这个命令 sudo mysql。Server start <——同样，确切的语法可能有所不同在mysql (http://dev.mysql.com/doc/refman/5.7/en/create-user.html)中创建用户。请记住为root用户添加密码。

首先，确保安装了自制程序运行brew doctor，解决任何homebrew想要你解决的问题运行brew install mysql 运行brew services重启mysql 运行mysql。服务器启动运行mysql_secure_installation

尝试授予权限命令mysql

当我使用最新版本的mysql和yosemite使用brew时，上面的答案(或者我在其他地方看到的几十个答案中的任何一个)都不适用。我最终通过brew安装了一个不同的mysql版本。

通过(例如)指定旧版本

brew install mysql56

为我工作。希望这能帮助到一些人。这是一个令人沮丧的问题，我觉得我永远被困住了。

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n

By default, MySQL comes with a database named 'test' that
