1. Virtual host configuration file httpd-vhosts.conf
Modify the Web log setting CustomLog to the following format
The code is as follows:
CustomLog "|/usr/local/sbin/cronolog /www/logs/example_%Y%m%d.log" combined
Of course, the error log setting ErrorLog can also be divided by cronolog, set to
The code is as follows:
ErrorLog "|/usr/local/sbin/cronolog /www/logs/error_%Y%m%d.log"
2, if there is only one site on the server (of course, this situation is relatively rare), directly according to the above format to modify the httpd.conf file log settings.
Description:
The green part is the location of cronolog after installation. The location may not be exactly the same for different system versions. The location viewed by which command shall prevail.
The blue part is the location of the set log file, which can be modified as needed;

# DocumentRoot /www/docs/dummy-host.example.com
# ServerName dummy-host.example.com
ErrorLog /data/logs/apache/webapps.wps.cn-error_log
CustomLog "|/usr/local/sbin/cronolog /data/logs/apache/%Y%m%d/access_log.% H" combined
#This ensures that a folder every day generates a log every hour under the folder
#CustomLog "|/usr/local/sbin/cronolog /data/logs/apache/%Y%m%%Hdaccess_log" combined
Go to/etc/init.d/httpd configtest to verify that your configuration file is correct
Go to/etc/init.d/httpd restart Restart the apache server (different systems should be different to find)
