█▌ - APACHE2 LOGS - █▌
█▌ █▌
█ ▐▌
█ Once you feel your server is setup properly you can reduce the load by ▐▌
█ disabling some/all of the Apache logs. I like to keep only my error.logs ▐▌
█ for trouble shooting since I test install a variety of programs; so I'll ▐▌
█ adjust logrotate settings for it. I don't have any need for any of the ▐▌
█ other log files so I'll completely disable those (access.log, ▐▌
█ other_vhosts_access.log and ssl_access.log). Adjust to your needs. This is ▐▌
█ how I did it: ▐▌
█ ▐▌
█ DISABLING AN APACHE2 LOG: ▐▌
█ ````````````````````````` ▐▌
█ Apache2 logs are here: ▐▌
█ ls -al /var/log/apache2/ ▐▌
█ ▐▌
█ To find in your own configuration files where it is stated to log, search ▐▌
█ your relevant apache configuration files, for example: ▐▌
█ su ▐▌
█ cat /etc/apache2/apache2.conf | grep .log ▐▌
█ Or search for the name of each log, for example access.log: ▐▌
█ cat /etc/apache2/sites-available/default | grep access ▐▌
█ ▐▌
█ Or I like this method that gives me a more complete list to go through: ▐▌
█ grep -r other_vhosts_access /etc/apache2/* ▐▌
█ grep -r .log /etc/apache2/* ▐▌
█ ▐▌
█ 1) So from my output above I'll disable logs in these files: ▐▌
█ pico /etc/apache2/apache2.conf ▐▌
█ search for .log (Ctrl+w) or which ever log you want to disable. ▐▌
█ ▐▌
█ Disable it by 'commenting it out' - adding before the line a: # ▐▌
█ It has this: ▐▌
█ # Define an access log for VirtualHosts that don't define their own logfile▐▌
█ CustomLog /var/log/apache2/other_vhosts_access.log vhost_combined ▐▌
█ Change it to: ▐▌
█ # Define an access log for VirtualHosts that don't define their own logfile▐▌
█ #CustomLog /var/log/apache2/other_vhosts_access.log vhost_combined ▐▌
█ ▐▌
█ 2) Then: ▐▌
█ pico /etc/apache2/sites-available/default ▐▌
█ Comment out this line: ▐▌
█ CustomLog /var/log/apache2/access.log combined ▐▌
█ ▐▌
█ 3) Then: ▐▌
█ pico /etc/apache2/sites-available/ajaxterm ▐▌
█ Comment out both of these lines: ▐▌
█ CustomLog /var/log/apache2/access.log combined ▐▌
█ CustomLog /var/log/apache2/access.log combined env=!dontlog ▐▌
█ ▐▌
█ Note: Your changes will also show in 'sites-enabled' if you had previously ▐▌
█ created those as symbolic links (ln -s) for example: ▐▌
█ cat /etc/apache2/sites-enabled/ajaxterm ▐▌
█ ▐▌
█ 4) Then: ▐▌
█ pico /etc/apache2/sites-available/default-ssl ▐▌
█ Comment out both of these lines: ▐▌
█ CustomLog /var/log/apache2/ssl_access.log combined ▐▌
█ CustomLog /var/log/apache2/access.log combined env=!dontlog ▐▌
█ ▐▌
█ 5) Then to have the changes take affect: ▐▌
█ /etc/init.d/apache2 restart ▐▌
█ If you are running ajaxterm: ▐▌
█ /etc/init.d/ajaxterm restart ▐▌
█ ▐▌
█ 6) If you would like to test your changes, check the time stamps for the ▐▌
█ last 5 entries: ▐▌
█ tail -5 access.log ▐▌
█ Then open one of your web pages on each site you have enabled, then tail ▐▌
█ again, you shouldn't see any new entries: ▐▌
█ tail -5 access.log ▐▌
█ ▐▌
█ 7) Then to delete your logs files: ▐▌
█ Access logs: ▐▌
█ rm /var/log/apache2/access.log.*.gz ▐▌
█ Or to remove including present file: ▐▌
█ rm /var/log/apache2/access.* ▐▌
█ ▐▌
█ Error logs: ▐▌
█ rm /var/log/apache2/error.log.*.gz ▐▌
█ ▐▌
█ Other vhosts logs: ▐▌
█ rm /var/log/apache2/other_vhosts_access.* ▐▌
█ ▐▌
█ APACHE LOG ROTATION: ▐▌
█ ```````````````````` ▐▌
█ man logrotate ▐▌
█ Or you can view it HERE. ▐▌
█ Since I have left error logging enabled, I would like to rotate the log ▐▌
█ more often than its default of weekly. To do so we need to change apache2 ▐▌
█ directives in its logrotate file: ▐▌
█ ▐▌
█ pico /etc/logrotate.d/apache2 ▐▌
█ Has this: ▐▌
/var/log/apache2/*.log {
weekly
missingok
rotate 52
compress
delaycompress
notifempty
create 640 root adm
sharedscripts
postrotate
if [ -f "`. /etc/apache2/envvars ; echo ${APACHE_PID_FILE:-/var/run/apache2.pid}`" ]; then
/etc/init.d/apache2 reload > /dev/null
fi
endscript
}
█ ▐▌
█ I change these two lines so that it rotates daily and keeps no more than ▐▌
█ one file: ▐▌
█ daily ▐▌
█ rotate 1 ▐▌
█ ▐▌
█ To test changes, but NOT actually rotate your logs: ▐▌
█ logrotate --debug --force /etc/logrotate.d/apache2 ▐▌
█ ▐▌
█ To rotate the logs manually: ▐▌
█ logrotate --force -v /etc/logrotate.d/apache2 ▐▌
█ ▐▌
█ Or to test rotate all logs handled by logrotate: ▐▌
█ logrotate --debug --force /etc/logrotate.conf ▐▌
█ ▐▌
█ So in the end I now have only /var/log/apache2/error.log and its backup ▐▌
█ from the day before error.log.1 ▐▌
█ ▐▌
