3.2.4.4. rotatelogs - Piped logging program to rotate Apache logs

rotatelogs是一个配合Apache管道日志功能使用的简单程序。举例：

rotatelogs logfile [ rotationtime [ offset ]] | [ filesizeM ]

选项
logfile
它加上基准名就是日志文件名。如果logfile中包含’%'，则它会被视为用于的strftime(3)的格式字串；否则，它会被自动加上以秒为单位的.nnnnnnnnnn后缀。这两种格式都表示新的日志开始使用的时间。
rotationtime
日志文件回卷的以秒为单位的间隔时间
offset
相对于UTC的时差的分钟数。如果省略，则假定为0，并使用UTC时间。比如，要指定UTC时差为-5小时的地区的当地时间，则此参数应为-300。
filesizeM
指定回卷时以兆字节为单位的后缀字母M的文件大小，而不是指定回卷时间或时差。

下列日志文件格式字串可以为所有的strftime(3)实现所支持，见各种扩展库对应的strftime(3)的手册。
%A 星期名全称(本地的)
%a 3个字符的星期名(本地的)
%B 月份名的全称(本地的)
%b 3个字符的月份名(本地的)
%c 日期和时间(本地的)
%d 2位数的一个月中的日期数
%H 2位数的小时数(24小时制)
%I 2位数的小时数(12小时制)
%j 3位数的一年中的日期数
%M 2位数的分钟数
%m 2位数的月份数
%p am/pm 12小时制的上下午(本地的)
%S 2位数的秒数
%U 2位数的一年中的星期数(星期天为一周的第一天)
%W 2位数的一年中的星期数(星期一为一周的第一天)
%w 1位数的星期几(星期天为一周的第一天)
%X 时间 (本地的)
%x 日期 (本地的)
%Y 4位数的年份

CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common
此配置会建立文件"/var/logs/logfile.nnnn"，其中的nnnn是名义上的日志启动时的系统时间(此时间总是滚动时间的倍数，可以用于cron脚本的同步)。在滚动时间到达时(在此例中是24小时以后)，会产生一个新的日志。

CustomLog "|bin/rotatelogs /var/logs/logfile 5M" common
此配置会在日志文件大小增长到5兆字节时滚动该日志。

ErrorLog "|bin/rotatelogs /var/logs/errorlog.%Y-%m-%d-%H_%M_%S 5M"
此配置会在错误日志大小增长到5兆字节时滚动该日志，日志文件名后缀会按照如下格式创建：errorlog.YYYY-mm-dd-HH_MM_SS

ErrorLog "| /usr/local/apache/bin/rotatelogs /www/logs/www.example.com/error_%Y_%m_%d_log 86400 480"
CustomLog "| /usr/local/apache/bin/rotatelogs /www/logs/www.example.com/access_%Y_%m_%d_log 86400 480" common

CustomLog "|/usr/local/httpd/bin/rotatelogs /www/logs/www.example.com/access.%Y-%m-%d.log 86400 480" combined
			

86400：表示 24小时 60*60*24

480: 表示时区偏移 8 时区等于 60*8

3.2.4.8. logger

https://www.sit.auckland.ac.nz/Logging_to_syslog_with_Apache

			
Logging to syslog with Apache

First you will need to install syslog-ng. This is the logging server that will send the log data to the syslog box.

apt-get update && apt-get install syslog-ng
syslog-ng uses a socket device to accept data from apache or whatever program is creating the logs.

Use the configuration here: Syslog-ng default config.

The first part indicates what the socket will be called and where it will live. The second part tells syslog-ng where to send the collected data. The restart syslog-ng (/etc/init.d/syslog-ng restart)l.

Configure apache's logging

Add these directives to send apache's logs via a socket to syslog

CustomLog "|/usr/bin/logger -s -t 'monitor.cs.auckland.ac.nz' -p info -u /var/log/apache_log.socket" Combined
ErrorLog "|/usr/bin/logger -s -t 'monitor.cs.auckland.ac.nz' -p err -u /var/log/apache_log.socket"
Apache will then use the logger program to send data to syslog. /var/log/apache_log.socket refers to the device that syslog-ng has created. Data sent to this device is sent over the network to the main syslog box.

Troubleshooting

It seems that apache 2.0.54-5 does not like logging to a file and to a process at the same time. In this case log entries will become re-ordered or missed out. You can use the test scripts below to check if this is happening.

Testing

Here are some useful scripts that can help with testing to make sure the logging is working as expected.

You can simulate http accesses using lynx with this command:

watch lynx -source http://monitor.cs.auckland.ac.nz/
Which will make a http request every two seconds. Or, for a better test:

for i in `seq 1 100`; do lynx -source http://monitor.cs.auckland.ac.nz/$i;sleep 3;done
The result of this test is a sequence of log entires from 1 to 100. If entries are missing or in the wrong order, you know there is a problem.
