找到mysql sokcet的路徑
vim /etc/mysql/mysql.conf.d/mysqld.cnf
socket = /var/run/mysqld/mysqld.sock
在php.ini中關於mysql的socket路徑的地方，修改如如下
[Pdo_mysql] ; If mysqlnd is used: Number of cache slots for the internal result set cache ; http://php.net/pdo_mysql.cache_size pdo_mysql.cache_size = 2000 ; Default socket name for local MySQL connects. If empty, uses the built-in ; MySQL defaults. ; http://php.net/pdo_mysql.default-socket pdo_mysql.default_socket=/var/run/mysqld/mysqld.sock
