Introduction to Apache log cutting under Linux

One, Cronolog

Download Ronolog Package: wget-p/usr/lcoal http://cronolog.org/download/cronolog-1.6.2.tar.gz

1,install:

307 Customlog "|/usr/local/sbin/cronolog/alidata/server/httpd/logs/access_%w.log" combined
The logs are stored under/alidata/server/httpd/logs/, named after the Access_ and Error_, at the end of%w.log, and the%w represents a day of 0-6, from the start calculation, has been polling

Cronolog configuration:

After the Ronolog installation is complete, the default/usr/local/sbin/cronolog

In $apache.conf (or vhosts configuration file)

Error Log "|cronolog location/log store path%w cycle. Log
ErrorLog "|/usr/local/sbin/cronolog/alidata/server/httpd/logs/error%w.log"

Access Log "|cronolog location/log store path%w cycle. Log combined end

Customlog "|/usr/local/sbin/cronolog/alidata/server/httpd/logs/access%w.log" combined

When the settings are complete, the log is automatically split from the date form (daily). such as: Access_0.log, until the end of Access_6.log, the next cycle is rotation cover, only keep the latest 7 days log!

Two: Rotatelogs Division

Find Rotatelogs Position

[Root@localhost local]# Find/-name rotatelogs
/usr/sbin/rotatelogs

Modify configuration file

ErrorLog "| /usr/sbin/rotatelogs/var/log/httpd/error_%y%m%d.log 86400 480 "
Customlog "| /usr/sbin/rotatelogs/var/log/httpd/access_%y%m%d.log 86400 "Common

86,400:86,400 represents a day, that is, a new log file is generated on a daily basis.
480: The number of minutes of time difference relative to UTC. If omitted, the default is 0, and UTC time is used. For example, to specify local time for a region that has a UTC difference of 5 hours, this should be-300, Beijing time is +8, and should be set to 480. So the time in the log will be consistent with the time on the server, easy to view the log.
