当我运行 php 在我的服务器中时，我收到此警告 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/pdo_mysql.so' - /usr/lib/php/20151012/pdo_mysql.so: undefined symbol: mysqlnd_connect in Unknown on line 0

Answer 1

我必须确保 /usr/lib/php/20151012/mysqlnd.so 存在并且我的模块已被 /etc/php/7.0/mods-available 目录启用，有多个 .ini 文件，除了 mysqlnd.ini

所以我创建了它

sudo nano mysqlnd.ini

并把这个内容：

; configuration for php common module
; priority=10
extension=mysqlnd.so

重启apache

sudo service apache2 restart
