mysql命令

1.执行 mysql命令，会提示 command not found，需要把mysql的命令映射到  usr/bin中。

MacBook-Pro:/ root# ln -s /usr/local/mysql/bin/mysql /usr/bin  

2.  mac 上启动mysql

sudo /usr/local/mysql/support-files/mysql.server start
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server restart

3.下载mysql,打开控制台：

　　sudo rm /usr/local/mysql

　　sudo rm -rf /usr/local/mysql*

　　sudo rm -rf /Library/StartupItems/MySQLCOM

　　sudo rm -rf /Library/PreferencePanes/My*

　　vim /etc/hostconfig and removed the line MYSQLCOM=-YES-rm -rf ~/Library/PreferencePanes/My*

　　sudo rm -rf /Library/Receipts/mysql*

　　sudo rm -rf /Library/Receipts/MySQL*

　　sudo rm -rf /var/db/receipts/com.mysql.* 最后这条很多文章都丢了，切记切记。

3. 对某个路径拥有 owner

sudo chown -R mysql /usr/local/mysql/data
