2.0-apache Log Cutting

Apache will generate access logs and error logs by default under/usr/local/apache2/logs after the service is available Access_log and error_log

In particular, the access log, in the case of multiple user access, will produce a lot of records. Over time, it may turn into a few g or more than 10 g.

In order to alleviate this situation, cutting logs by day, deleting previously useless logs, is a good workaround.

First of all, the system generates the Access log format by default:

Vim/usr/local/apache2/conf/httpd.conf

<ifmodule log_config_module>

#

# The following directives define some format nicknames for use with

# a Customlog directive (see below).

#

Logformat "%h%l%u%t \"%r\ "%>s%b \"%{referer}i\ "\"%{user-agent}i\ "" combined

Logformat "%h%l%u%t \"%r\ "%>s%b" common

<ifmodule logio_module>

# need to enable MOD_LOGIO.C to use%I and%O

Logformat "%h%l%u%t \"%r\ "%>s%b \"%{referer}i\ "\"%{user-agent}i\ "%I%O" Combinedio

</IfModule>

There are three types of combined common and combinedio formats

The more commonly used are combined types

%h indicates that the source IP%u indicates that the user name%t represents the time%r represents the action, such as: GET detailed instructions, please see the official manual

Configuration steps:

1.vim/usr/local/apache2/conf/extra/httpd-vhosts.conf

Turn on the default logging feature

Errorlog "Logs/dummy-host.example.com-error_log"

Customlog "Logs/dummy-host.example.com-access_log" common

2. Modify the Access log type to combined

Customlog "Logs/dummy-host.example.com-access_log" combined

3. Add Cut command, post-cut log absolute path and custom timestamp log name Finally, add the cut condition, that is, 24 hours to cut once.

Customlog "|/usr/local/apache2/bin/rotatelogs-l/usr/local/apache2/logs/%y%m%d-access_log 86400" combined

Note: It is automatically cut on-the-go, separated by days, and it will automatically generate a new log file in the next second of 2015-01-03 23:59:59.
