升级php 7.0之后,由于php7.0不再支持mysql扩展,只好升级为pdo mysql方式。 装好php7.0新环境之后,遇到CDbConnection 无法开启数据库连线: SQLSTATE[HY000] [2002]错误 解决方式: 在centos里边,通过 find / -name mysql.sock 找到 /var/lib/mysql/mysql.sock 然后找到 php.ini 修改 pdo_mysql.default_socket= /var/lib/mysql/mysql.sock mysqli.default_socket =/var/lib/mysql/mysql.sock 解决问题。
The above introduces the YIi PDO CDbConnection cannot open the database connection: SQLSTATE[HY000] [2002], including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
