Hi, FreeRADIUS starts with my virtual machine. Therefore Ubuntu created the file "radiusd.service" itself. I activated "radius.service" with "systemctl enable radiusd.service" so that FR starts with the virtual machine. Now the problem when FR starts with the virtual machine is that the following error message can be found in the log file: Mon Oct 22 08:45:40 2018 : Info: Debugger not attached Mon Oct 22 08:45:41 2018 : Info: rlm_sql (sql): Driver rlm_sql_mysql (module rlm_sql_mysql) loaded and linked Mon Oct 22 08:45:42 2018 : Info: rlm_sql_mysql: libmysql version: 5.7.23 Mon Oct 22 08:45:42 2018 : Info: rlm_sql (sql): Attempting to connect to database "radius" Mon Oct 22 08:45:42 2018 : Info: rlm_sql (sql): Opening additional connection (0), 1 of 32 pending slots used Mon Oct 22 08:45:42 2018 : Error: rlm_sql_mysql: Couldn't connect to MySQL server radius@localhost:radius Mon Oct 22 08:45:42 2018 : Error: rlm_sql_mysql: MySQL error: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) Mon Oct 22 08:45:42 2018 : Error: rlm_sql (sql): Opening connection failed (0) Mon Oct 22 08:45:42 2018 : Error: /etc/raddb/mods-enabled/sql[20]: Instantiation failed for module "sql" If I restart FR with "systemctl restart radiusd.service" this error does not occur. Can anyone help me? regards Lukas
