找到mysql sokcet的路径
vim /etc/mysql/mysql.conf.d/mysqld.cnf
socket = /var/run/mysqld/mysqld.sock
在php.ini中关于mysql的socket路径的地方,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
