MariaDB数据库安全调整

MariaDB第一次安装后，修改一些默认的配置，使数据库更加安全。

mysql -e “DELETE FROM mysql.user WHERE User=’’” mysql -e “DELETE FROM mysql.user WHERE User=‘root’ AND Host NOT IN (’localhost’, ‘127.0.0.1’, ‘::1’)” mysql -e “DROP DATABASE test;” mysql -e “DELETE FROM mysql.db WHERE Db=‘test’ OR Db=‘test\\ _%’“ mysql -e “FLUSH PRIVILEGES”
