在小牛上使用Homebrew安裝MySQL的問題

Question

我在小牛上安裝MySQL和Homebrew有瘋狂的問題。我知道有一個類似的命名主題，但我已經嘗試了與至少20個網站一起寫入的所有內容，但都沒有嘗試使其正常工作。我嘗試根據不同的教程安裝步驟，但沒有任何工作，因爲它應該。

我是這樣的：

brew update 
brew doctor 
brew upgrade 

brew install mysql 

啤酒將其安裝在/usr/local/Cellar/mysql/5.6.16 ...

我嘗試連接的釀造說：mysql -uroot

我做LaunchAgents目錄，自制的plist文件鏈接到它和發射控制：

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

之後，我試着和sudo mysql.server start啓動MySQL服務器，但我得到一個套接字錯誤

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

我試着以mysqld_safe &服務器，但我得到以下輸出：

[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 

以下命令似乎這樣的伎倆 須藤搭配chmod -R 755在/ usr /本地的/ var/mysql的 室射頻/usr/local/var/mysql/Davids-MacBook-Air-5.local.err

mysql.server restart 

和MySQL服務器成功地啓動

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

其他時候，不管我做什麼，我不斷收到以下錯誤

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

有些建議做

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

但我沒有成功修復這個問題。

任何幫助，將不勝感激。我希望我詳細描述了這個問題。如果沒有，我會很樂意提供更多信息。

編輯：我嘗試mysqld的重新啓動，我得到更多的錯誤：

Answer 1

昨天我們遇到了同樣的問題。 我的錯誤是在執行

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

在第一時間，但forgot卸載它。幾條線索：

1. 過程mysqld_safe運行下root
2. 過程mysql運行下_mysql
3. 他們都up和down連連。
4. 錯誤文件/usr/local/var/mysql/*.err的所有者是_mysql
5. 運行sudo launchctl list | grep mysql時，存在一個mysql服務

解決方法很簡單：

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

根本原因是，自制的MySQL的不假設在root下運行，至少看起來好像。

也許這不是你的問題，但我希望它會有所幫助。

Answer 2

這主要看起來像一個權限問題。這兩行很關鍵：

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! 

我可以看到你在mysql文件上設置了權限，但你也應該檢查所有權。用自制軟件做sudo chown -R david:staff /usr/local以及sudo chmod u+rwX /usr/local（一個比0755權限更好的選項）通常是安全的，而且在homebrew下的mysql應該像你一樣運行。

當你安裝，我建議你考慮使用Percona server版本的MySQL這是自制軟件也可作爲percona-server。你也可以考慮MariaDB--它們都是對於vanilla MySQL的替代品，並且具有一些優勢。
