关于日志选项配置：

        // If there is a firewall between you and nameservers you want
        // to talk to, you might need to uncomment the query-source
        // directive below.  Previous versions of BIND always asked
        // questions using port 53, but BIND 8.1 and later use an unprivileged
        // port by default.
