【问题描述】：

我在 Mavericks 上使用 Homebrew 安装 mysql 时遇到了严重的问题。我知道有一个类似名称的主题，但我已经尝试了那里写的所有内容以及至少 20 个站点，但没有成功尝试使其工作。我尝试根据不同的教程安装步骤，但没有任何效果。

我是这样去的：

brew update
brew doctor
brew upgrade

brew install mysql

Brew 将其安装在 /usr/local/Cellar/mysql/5.6.16 ...

我尝试按照 Brew 所说的进行连接：mysql -uroot

我创建 LaunchAgents 目录，将自制 plist 文件链接到它并启动控件：

mkdir -p ~/Library/LaunchAgents
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

之后我尝试使用 sudo mysql.server start 启动 mysql 服务器，但出现套接字错误

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

我尝试使用mysqld_safe & 启动服务器，但得到以下输出：

[1] 69187
Davids-MacBook-Air-5:~ davidsupan$ 140224 14:39:16 mysqld_safe Logging to     '/usr/local/var/mysql/Davids-MacBook-Air-5.local.err'.
touch: /usr/local/var/mysql/Davids-MacBook-Air-5.local.err: Permission denied
140224 14:39:16 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
/usr/local/bin/mysqld_safe: line 129: /usr/local/var/mysql/Davids-MacBook-Air-5.local.err: Permission denied
/usr/local/bin/mysqld_safe: line 166: /usr/local/var/mysql/Davids-MacBook-Air-5.local.err: Permission denied
140224 14:39:16 mysqld_safe mysqld from pid file /usr/local/var/mysql/Davids-MacBook-Air-5.local.pid ended
/usr/local/bin/mysqld_safe: line 129: /usr/local/var/mysql/Davids-MacBook-Air-5.local.err: Permission denied

以下命令似乎可以解决问题 sudo chmod -R 755 /usr/local/var/mysql rm -Rf /usr/local/var/mysql/Davids-MacBook-Air-5.local.err

mysql.server restart

mysql服务器成功启动

Shutting down MySQL
.. SUCCESS! 
Starting MySQL
. SUCCESS! 

其他时候，无论我做什么，我都会不断收到以下错误

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

一些页面建议这样做

unset TMPDIR
mysql_install_db --verbose --user='whoami' \\
--basedir="$(brew --prefix mysql)" \\
--datadir=/usr/local/var/mysql --tmpdir=/tmp

但我没有成功解决这个问题。

任何帮助将不胜感激。我希望我对问题的描述足够详细。如果没有，我很乐意提供更多信息。

编辑：我尝试 mysqld restart 得到更多错误：

【问题讨论】：

你能找到你的 my.cnf 文件吗？

不，我在任何文件夹中都找不到 my.cnf 文件。

你试过通过 brew 卸载 mysql 吗？ ***.com/questions/4359131/… 如果是这样，您也许可以使用 brew 重新安装它

我试过多次卸载它。它总是会出现同样的错误。

我只是能够通过从我的 /etc 目录中删除一个无关的 my.cnf 文件来解决我的问题。见***.com/questions/2482234/…

【参考方案1】：

我们昨天遇到了同样的问题。 我的错误是执行

sudo launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

第一次，但forgot 卸载它。几个线索：

一个进程mysqld_safe在root下运行 一个进程mysql 在_mysql 下运行 up 和 down 一次又一次。 错误文件/usr/local/var/mysql/*.err的所有者是_mysql 运行sudo launchctl list | grep mysql时，存在mysql服务

解决方法很简单：

sudo launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

根本原因是，homebrew 的 mysql 不假定在root 下运行，至少看起来是这样。

也许它和你的问题不一样，但我希望它会有所帮助。

【参考方案2】：

这主要看起来像一个权限问题。这两行很关键：

2014-02-25 12:35:54 34599 [ERROR] InnoDB: ./ibdata1 can't be opened in read-write mode
2014-02-25 12:35:54 34599 [ERROR] InnoDB: The system tablespace must be writable!

我可以看到您对 mysql 文件设置了权限，但您可能也应该检查所有权。使用 homebrew 通常可以安全地使用 sudo chown -R david:staff /usr/local 和 sudo chmod u+rwX /usr/local（比 0755 权限更好的选择），并且 homebrew 下的 mysql 应该像你一样运行。

在安装时，我建议您考虑使用 MySQL 的 Percona server 版本，该版本在自制软件中也可作为 percona-server 使用。您也可以考虑 MariaDB - 它们都是普通 MySQL 的直接替代品，并且具有一些优势。
