在 mac os el capitan 上安装 mysql

Question

我正在尝试按照 this link、

中的方法在 MAC OS 版本 10.11.2 上安装 mysql

已成功执行以下命令，

brew install mysql

但是当我键入以下命令时，

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

我收到以下错误：

mysql_install_db: [ERROR] unknown variable 'tmpdir=/tmp'
2015-12-17 17:35:54 [ERROR]   Unrecognized options

请帮忙。提前致谢。

基于此 link：https://bugs.launchpad.net/mysql-sandbox/+bug/1396092 and this https://blog.omgmog.net/post/installing-mysql-on-os-x-mountain-lion/ 看起来您可能只需要在 运行 install_db 命令之前 unset TMPDIR。

Answer 2

试试 运行 这个，它对我有用。 （从找到的评论中得到它here）

mysqld -initialize --verbose --user=whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

张贴在这里以防万一有人遇到和我一样的问题。

所有功劳归于coder wall

完全删除 MySQL

1. ps -ax | grep mysql stop and kill any MySQL processes
2. brew remove mysql
3. brew cleanup
4. sudo rm /usr/local/mysql
5. sudo rm -rf /usr/local/var/mysql
6. sudo rm -rf /usr/local/mysql*
7. sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
8. sudo rm -rf /Library/StartupItems/MySQLCOM
9. sudo rm -rf /Library/PreferencePanes/My*
10. launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
11. edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
12. rm -rf ~/Library/PreferencePanes/My*
13. sudo rm -rf /Library/Receipts/mysql*
14. sudo rm -rf /Library/Receipts/MySQL*

用 Homebrew 重新安装 MySQL

3. brew install mysql
4. unset TMPDIR
5. mysqld -initialize --log-error-verbosity --user=whoami --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
6. mysql.server start
7. brew services start mysql
