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

好久不用mysql，今天突然想用的時候，

mysql -uroot -p

直接報了下面的錯誤

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

mac可以在設置里面啟動mysql，設置里面啟動mysql的時候提示沒有/usr/local/mysql/data的權限，

給予權限

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

發現還是沒用，但是發現mysql當時是配置了鏈接

qiweijieMacBook-Pro:~ qiweijie$ ll /usr/local/mysql

lrwxr-xr-x  1 _mysql  _mysql  27  2 26  2016 /usr/local/mysql -> mysql-5.7.11-osx10.9-x86_64

雖然給了mysql權限，還是只是給到了鏈接的權限，沒有得到真正的mysql目錄的權限

qiweijieMacBook-Pro:~ qiweijie$ ll /usr/local/mysql-5.7.11-osx10.9-x86_64/

total 48
...
drwxr-x---  16 qiweijie  staff    544 10  7 12:18 data
....

sudo chown -R mysql:mysql  /usr/local/mysql-5.7.11-osx10.9-x86_64/

這樣就好了
