Question

我在使用Homebrew在Mavericks上安装MySQL时遇到了疯狂的问题。我知道有一个类似命名的主题，但我已经尝试了所有写在那里的所有内容以及至少20个网站但没有成功尝试使它工作。我尝试根据不同的教程安装步骤，但没有任何工作可以。

我是这样的：

brew update
brew doctor
brew upgrade

brew install mysql

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

我尝试连接，如Brew说：mysql -uroot

我创建LaunchAgents目录，将自制的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

之后我尝试用sudo mysql.server start启动mysql服务器，但是我收到套接字错误

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，但我得到以下输出：

[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
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

并且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，我都会收到以下错误

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

有些网页建议

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。我希望我能详细描述这个问题。如果没有，我很乐意提供更多信息。

编辑：我尝试 mysqld restart ，我得到更多错误：

Answer 1

这主要看起来像权限问题。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!

我可以看到你设置mysql文件的权限，但你也应该检查所有权。使用自制程序时，sudo chown -R david:staff /usr/local以及sudo chmod u+rwX /usr/local（比0755权限更好的选项）通常是安全的，而且自制程序下的mysql应该像你一样运行。

在您安装时，我建议您考虑使用MySQL的Percona server版本，该版本也可以作为percona-server在自制软件中使用。您还可以考虑使用MariaDB - 它们都是vanilla MySQL的替代品，并且具有一些优势。

Answer 2

我们昨天遇到了同样的问题。我的错误在于执行

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

第一次，但forgot卸载它。几条线索：

流程mysqld_safe在root
流程mysql在_mysql
他们一次又一次地up和down。
错误文件/usr/local/var/mysql/*.err的所有者为_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，自制软件的mysql不会被假定在root下运行，至少看起来如此。

也许这与你的问题不一样，但我希望它会有所帮助。
