Passiamo a settare Logrotate del nostro Server Proxy. Logrotate serve a rigenerare i file di log periodicamente:<\/p>\n

Per \u201cbloccare\u201d la rigenerazione dei file di log ogni sera devi effettuare una piccola modifica al file che si trova in \/etc\/logrotate.d\/ all\u2019interno trovi le personalizzazioni di compattamento e rigenerazione dei file di log per alcuni servizi.
\nSolitamente il file di configurazione generale di logrotate si trova in \/etc\/logrotate.conf (meglio non toccarlo perch\u00e9 andrebbe ad incidere su tutti i file di log
\n\u2013 io l\u00ec, ho solo aggiunto (cos\u00ec da risparmiare spazio sul disco, comprimendo i file di log vecchi):
\n# uncomment this if you want your log files compressed
\nCompress #di<\/a> default \u00e8 commentato<\/p>\n

Per personalizzare il settaggio del file di logrotate di dansguardian al fine di evitare le rigenerazione del file log basta cambiare il parametro:
\nrotate portandolo ad un valore di 400 (dovrebbe corrispondere ad un anno solare) invece che 5 (valore di serie)\u2014Almeno questo ho letto su un guida internet:
\nhttp:\/\/www.tic.fdns.net\/tic\/html\/uml-bering.html<\/a><\/p>\n

Riporto il testo del sito:
\n\u201cPer i vincoli dovuti alle norme sulla privacy occorre configurare il server proxy in modo che vengano mantenuti i file di log per almeno un anno e nel contempo attivare una procedura di backup e salvataggio degli stessi a livello trimestrale. Il programma da configurare per il salvataggio dei log si chiama logrotate che nel caso di squid sar\u00e0 configurato come segue:
\n# \/etc\/logrotate.d\/squid
\n# Logrotate fragment for squid
\n\/var\/log\/squid\/*.log {
\ndaily
\ncompress
\ndelaycompress
\nrotate 400
\nmissingok
\nnocreate
\nsharedscripts
\nprerotate
\ntest ! -x \/usr\/sbin\/sarg-maint || \/usr\/sbin\/sarg-maint
\nendscript
\npostrotate
\ntest ! -e \/var\/run\/squid.pid || \/usr\/sbin\/squid -k rotate
\nendscript
\n}
\nPer l\u2019analisi delle prestazioni del proxy tramite il programma sarg \u00e8 preferibile settare la raccolta differenziata per mese:
\n# \/etc\/cron.monthly\/squid
\n#Get<\/a> current date
\nTODAY=$(date +%d\/%m\/%Y)<\/p>\n

#Get<\/a> current date
\nTD=$(date \u2013date \u201c1 month ago\u201d +%Y-%m)<\/p>\n

#Get<\/a> one month ago today
\nYESTERDAY=$(date \u2013date \u201c1 month ago\u201d +%d\/%m\/%Y)<\/p>\n

#Get<\/a> one month ago today (4touch)
\nYD=$(date \u2013date \u201c1 month ago\u201d +%m\/%d\/%Y)<\/p>\n

touch -d $YD \/tmp\/a
\ncat \/var\/log\/squid\/access.log.1 > \/var\/log\/squid\/monthly\/squid-$TD
\nfind \/var\/log\/squid\/ -newer \/tmp\/a -name access.log\\*gz | \\
\nxargs zcat >> \/var\/log\/squid\/monthly\/squid-$TD<\/p>\n

ln -f -s \/var\/log\/squid\/monthly\/squid-$TD \/var\/4sarg
\nsarg -o \/var\/www\/squid-reports\/monthly -d $YESTERDAY-$TODAY<\/p>\n

Attenzione che i log contengono dati sensibili e quindi quelli relativi agli utenti non possono essere consultati senza infrangere la Legge Italiana sulla privacy 196\/2003.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
