我试图在named.conf中找到完美的日志记录子句,这将帮助我为命名服务启用完整级别的日志.有人可以在这里举个例子吗？我现在的条款如下,但这会产生非常小的日志.

 logging {
     channel querylog{
             file "/var/log/querylog";
             severity debug 10;
             print-category yes;
             print-time yes;
             print-severity yes;
             };
     category queries { querylog;};
 };

我已经在中安装了Elasticsearch6.x Debian 7 (wheezy)。我尝试从开始service elasticsearch start但它给我一个错误信息

root@debian:~# sudo -i service elasticsearch start
[FAIL] Starting Elasticsearch Server: failed!

我尝试查看位于的elasticsearch日志文件nano /var/log/elasticsearch/elasticsearch.log，但出现此错误

是否可以将多个换行符输入到多个变量中int并一次声明它们？

为了进一步解释我要完成的工作，我知道这是我们如何使用map进行空格分隔的输入：

>>> a, b = map(int, input().split())
3 5
>>> a
3
>>> b
5

有换行符吗？就像是：

a, b = map(int, input().split("\n"))

改写：我试图一次从多行中获取多个整数输入。
