这是Ubuntu系统的ntp配置文件中默认的NTP服务器地址。这里使用了NTP Pool Project提供的NTP服务器地址,它们是由全球志愿者维护的一组公共NTP服务器,这些服务器使用相同的DNS名称(例如0.ubuntu.pool.ntp.org)进行访问。当您的系统需要进行时间同步时,它将从这些NTP服务器中选择最近的一个,并与它进行通信以更新系统时间。这种方法可以保证系统时间的准确性和稳定性。

ntp.conf标准配置
以下是常见的ntp.conf标准配置:
```
# /etc/ntp.conf
# Use servers from the NTP Pool Project. Approved by Ubuntu Technical Board
pool 0.ubuntu.pool.ntp.org iburst
pool 1.ubuntu.pool.ntp.org iburst
pool 2.ubuntu.pool.ntp.org iburst
pool 3.ubuntu.pool.ntp.org iburst
# Use Ubuntu's ntp server as a fallback.
pool ntp.ubuntu.com
# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details. The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.
# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery limited
restrict -6 default kod notrap nomodify nopeer noquery limited
# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1
# Needed for adding pool entries
restrict source notrap nomodify noquery
# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust
# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
#broadcast 192.168.123.255
# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines. Please do this only if you trust everybody on the network!
#disable auth
#broadcastclient

这个配置文件包括了常见的NTP服务器池、访问控制、本地用户访问限制以及广播等设置。
插入 id = 4,article_id=2,created=2018-12-13,ip=0:0:0:0:0:0:0:1,content=好累啊,status=approved,author=坏笑好
您可以使用以下 SQL 语句插入相关数据:
```sql
INSERT INTO comments (id, article_id, created, ip, content, status, author)
VALUES (4, 2, '2018-12-13', '0:0:0:0:0:0:0:1', '好累啊', 'approved', '坏笑好');
```
其中,comments 为您的评论表名,id、article_id、created、ip、content、status、author 分别为您的评论表中的字段名,后面的值为需要插入的具体数据。请根据您的实际情况进行修改。注意,日期类型的数据需要使用引号括起来。
