default-time_zone = '+8:00'
# 设置密码验证规则，default_authentication_plugin参数已被废弃
# 改为authentication_policy
#default_authentication_plugin=mysql_native_password
authentication_policy=mysql_native_password


#secure_file_priv=/var/lib/mysql
secure_file_priv=
init_connect='SET collation_connection = utf8mb4_0900_ai_ci'
init_connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
