1. bind 配置
这里只是定义了一个简单的 channel 详细的日志定义请查看 https://www.cnblogs.com/zy09/p/13214902.html
channel default_syslog { syslog local0; //我们使用一个尚未使用 的local0 名称 severity dynamic; };
根据官当资料 http://web.mit.edu/darwin/src/modules/bind/bind/doc/html/logging.html
给出的建议如下：
Syntax logging { [ channel channel_name { ( file path_name [ versions ( number | unlimited ) ] [ size size_spec ] | syslog ( kern | user | mail | daemon | auth | syslog | lpr | //我们可以定义很多的syslog 发送的服务类型，在底部服务名称栏有详细描写 news | uucp | cron | authpriv | ftp | local0 | local1 | local2 | local3 | local4 | local5 | local6 | local7 ) | null ); [ severity ( critical | error | warning | notice | info | debug [ level ] | dynamic ); ] [ print-category yes_or_no; ] [ print-severity yes_or_no; ] [ print-time yes_or_no; ] }; ] [ category category_name { channel_name; [ channel_name; ... ] }; ] ... };
2.bind 服务器的 rsyslog 配置

3. 远程日志服务器配置
[root@kube data]# cat /etc/rsyslog.conf # rsyslog configuration file # For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html # If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html #### MODULES #### # The imjournal module bellow is now used as a message source instead of imuxsock. $ModLoad imuxsock # provides support for local system logging (e.g. via logger command) $ModLoad imjournal # provides access to the systemd journal #$ModLoad imklog # reads kernel messages (the same are read from journald) #$ModLoad immark # provides --MARK-- message capability # Provides UDP syslog reception #$ModLoad imudp $ModLoad imudp // 开启日志服务器的 udp 514 端口监听 #$UDPServerRun 514 $UDPServerRun 514 # Provides TCP syslog reception #$ModLoad imtcp #$InputTCPServerRun 514 #### GLOBAL DIRECTIVES #### # Where to place auxiliary files $WorkDirectory /var/lib/rsyslog # Use default timestamp format $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat # File syncing capability is disabled by default.

服务名称
syslog本身有设置一些服务，其他程序也可能设置一些，rsyslog设置的服务主要有下面这些，可以使用man 3 syslog查询到相关的信息。
|
服务类型 |
说明 |
|
auth |
pam产生的日志，认证日志 |
|
authpriv |
ssh，ftp等登录信息的验证信息 |
|
cron |
就是例行工作调度cron/at等生成信息日志的地方 |
|
daemon |
与各个daemon有关的信息 |
|
kern |
内核kernel产生信息的地方 |
|
lpr |
打印相关的信息 |
|
|
只要与邮件收发有关的信息记录都属于这个 |
|
mark（syslog） |
就是syslogd这个程序本身生成的信息 |
|
news |
与新闻组服务器有关的东西 |
|
user |
用户程序产生的相关信息 |
|
uucp |
unix to unix copy，unix主机之间相关的通讯 |
|
local 1~7 |
自定义的日志设备 |
上面谈到的都是syslog自行制定的服务名称，软件开发商可以通过调用上述的服务名称来记录他们的软件。
信息等级
|
等级 |
等级名称 |
说明 |
|
1 |
info |
一般信息的日志，最常用 |
|
2 |
notice |
除了info外还需要注意的一些信息内容 |
|
3 |
warning（warn） |
警示的信息，可能有问题，但是还不至于影响到某个daemon运行的信息；基本上info、notice、warn这三个信息都是在告知一些基本信息而已，应该还不至于造成一些系统运行困扰 |
|
4 |
err（error） |
一些重大的错误信息，例如配置文件的某些设置造成该服务无法启动的信息说明，通常通过error的错误告知，应该可以了解到该服务无法启动的问题 |
|
5 |
crit |
比error还要严重的错误信息，这个crit是临界点critcal的缩写，这个错误已经很严重了。 |
|
6 |
alert |
警告，已经很有问题的等级，比crit还要严重 |
|
7 |
emerg（panic） |
emergency/panic，急诊应急、疼痛、意指系统已经几乎要死机的状态！很严重的错误信息了。通常大概只有硬件出问题导致整个内核无法顺利运行，就会出现这样的等级的信息。 |
除了这些等级的信息外，还有两个特殊的等级，debug错误检测等级与none不需登录等级两个，当我们想要一些错误检测或者是忽略掉某些服务的信息时，就用这两个。
服务名称和信息登记之间的符号[.=!]说明
"."代表比后面还要高的等级含该等级，都被记录下来的意思，例如mail.info表示只要是mail的信息，而且该信息等级高于info含info本身时，就会被记录下来的意思
".="代表所需要的等级就是后面接的等级而已，其他不要
".!"代表不等于，即是除了该等级外的其他等级都记录。
一般说最常用的就是"."这个链接符号。
