mac 安装并使用 mysql 或者 mac mysql 忘记密码，Can't connect to local MySQL server through socket homebrew

1. brew install mysql

2. 启动mysql mysql.server start

我遇到了这个error，查openstack解决，我在这粘一下

### Error：Can't connect to local MySQL server through socket homebrew

When you got the server running via

mysql.server start

you should see the socket in /tmp/mysql.sock. However, the system seems to expect it in /var/mysql/mysql.sock. To fix this, you have to create a symlink in /var/mysql:

sudo mkdir /var/mysql

sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock

3. 配置密码等 mysql_secure_installation

4. 如果忘记密码，简单点，删除再装可以吧

删除

• sudo rm /usr/local/mysql

其实这一句就够了，以防万一，所有可能的地删除一遍

• sudo rm -rf /usr/local/mysql*
• sudo rm -rf /Library/StartupItems/MySQLCOM
• sudo rm -rf /Library/PreferencePanes/My*
• edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
• rm -rf ~/Library/PreferencePanes/My*
• sudo rm -rf /Library/Receipts/mysql*
• sudo rm -rf /Library/Receipts/MySQL*
• sudo rm -rf /private/var/db/receipts/*mysql*

5.  安装mysql-python

pip install mysql-python

遇到两个error 

1）“config.h” not  found

解决办法：

　　brew install mysql-connector-c 

　　

       CFLAGS=-Qunused-arguments CPPFLAGS=-Qunused-arguments pip install MySQL-python==1.2.5

 

2）“pip install mysql-python“   fails with  ’IndexError‘

 

By finding out the information that mysql-connector-cmight come to the conclusion that the configuration by brew installation may be incorrect , open the /usr/local/bin/mysql_config script to modify some of the contents of it:

#Create options
Libs = "-L $ pkglibdir "
Libs = " $ libs   -l"

change into:

#Create options
Libs = "- L $ pkglibdir"
Libs = "$ libs -lmysqlclient -lssl -lcrypto"
