是因为我之前悲催的把之前的账户删了

现在用的是全新的账户，目前的账户没有/usr/local/var/mysql 目录的写权限：

andy:var andy$ ll

total 0

drwxr-xr-x   6 501   admin  204  6 19 10:33 ./

drwxrwxr-x  20 root  admin  680  6 11 15:51 ../

drwxr-xr-x   3 501   admin  102  6 19 10:33 db/

drwxr-xr-x   2 501   admin   68  6 19 10:33 run/

授予权限：

andy:var andy$ sudo chmod 777 mysql

andy:var andy$ ll

有了写权限之后，就成功了~~
