无法链接驱动程序 rlm_sql_mysql

Question

我在使用 MySQL 时遇到问题：

freeradius -X 给出以下命令：

Could not link driver rlm_sql_mysql: /usr/lib/freeradius/rlm_sql_mysql.so: cannot open shared object file: No such file or directory
Make sure it (and all its dependent libraries!) are in the search path of your system's ld
/etc/freeradius/3.0/mods-enabled/sql[18]: Instantiation failed for module "sql

我还没有尝试安装 libmysqlclient 或 yum 或任何东西。 在我重新安装 freeradius 后，这个问题开始出现。

是否也需要以某种方式重新安装 mysql 数据库？

谢谢

就我而言，在降级 MySQL 版本后， libmysqlclient-dev库丢失了，只需要安装它即可。

apt install libmysqlclient-dev

希望，这有助于某人。
