Mac can't connect to local MySQL server through socket '/tmp/mysql Sock '(2) problem

Mac solve Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2) problem

I am here mac Computer installation mysql, Found connection failed ：

MacBook-Pro:etc chenxianchong$ mysql -uroot -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

The reason is simple , Can't find /tmp/mysql.sock This file , The solution is as follows ：
1、 modify my.cnf file , Usually in /etc/my.cnf Directory

Enter this file to modify , Put the previous socket = /tmp/mysql.sock Comment out , Then change another address
2、 Assign 777 jurisdiction

sudo chmod 777 /etc/mysqlsock/mysql.sock

3、 restart mysql

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

And then we'll try again mysql -uroot -p Found that you can log in
