在Mavericks上使用自制程序安装MySQL时出现问题

我在Mavericks上安装MySQL时遇到了疯狂的问题。我知道有一个类似的主题，但我尝试了那里写的所有东西，以及至少20个站点，但都没有成功。我尝试根据不同的教程使用步骤进行安装，但没有任何效果

我是这样说的：

brew update
brew doctor
brew upgrade

brew install mysql

Brew将其安装在/usr/local/ceral/mysql/5.6.16

我尝试按照Brew的说明进行连接：

mysql-uroot

我创建LaunchAgents目录，将自制plist文件链接到该目录，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，我尝试用

sudomysql.server start

启动mysql服务器，但是我得到了一个套接字错误

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

我尝试使用

mysqld\u 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'.

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

/usr/local/bin/mysqld_safe: line 129: /usr/local/var/mysql/Davids-MacBook-Air-5.local.err: Permission denied

下面的命令似乎可以做到这一点 sudochmod-r755/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，我总是会出现以下错误

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

有些网页建议这样做

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

但是我没有成功地解决这个问题

任何帮助都将不胜感激。我希望我描述的问题足够详细。如果没有，我很乐意提供更多信息

编辑：我尝试mysqld重新启动，但我得到了更多错误：

这看起来主要是权限问题。这两条线至关重要：

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，通常可以安全地执行

sudo chown-R david:staff/usr/local

以及

sudo chmod u+rwX/usr/local

（比

0755

权限更好的选项），并且homebrew下的mysql应该像您一样运行

---

在安装过程中，我建议您考虑使用MySQL版本，该版本在自制的percona服务器中也可用。你也可以考虑MiRADB——它们都是香草MySQL的替代品，并且有一些优势。

< P>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，但是

忘记了卸载它。一些线索：

进程
mysqld\u safe
在
root
进程
mysql
在
\u mysql
它们一次又一次地向上

和向下

错误文件

/usr/local/var/mysql/*.err

的所有者是

\u mysql

运行

sudo launchctl list | grep mysql

时，存在一个mysql服务

解决方案很简单：

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

根本原因是，至少看起来，homebrew的mysql并不是在

根目录下运行的

也许这与您的问题不同，但我希望它能有所帮助。
您能找到my.cnf文件吗？不，我在任何文件夹中都找不到my.cnf文件。您是否尝试过通过brew卸载mysql？如果是这样，您可能可以使用brew重新安装itI。我已经多次尝试卸载它。它总是出现同样的错误。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。看见
